Classification of stainless steel silencers:




铂莱娱乐场Classification of stainless steel mufflers (steam emission stainless steel mufflers, steam emission stainless steel mufflers, exhaust stainless steel mufflers, exhaust stainless steel mufflers, boiler fire exhaust stainless stel mufflers, boiler fire exhaust stainless steel mufflers, small hole stainless steel mufflers, small hole stainless steel mufflers, safety valve stainless steel mufflers, etc.) is used to eliminate steam pipeline venting The noise generated by pipelines (such as steam drum safety valve, fire exhaust, safety valve venting, and pressure relief of the autoclave) can be installed between pipelines, at the end of the pipeline venting, and outdoors.


Steam stainless steel muffler is a type of stainless steel muffler developed for steam emissions.


Installation and usage instructions for steam stainless steel muffler:


铂莱娱乐场1. Steam stainless steel silencers and exhaust pipes should be connected by welding or flanges.


铂莱娱乐场2. The lifting process of steam stainless steel muffler should prevent deformation or collision of the shell.


Several forms of steam stainless steel silencers:


铂莱娱乐场1. Boiler - Fire exhaust stainless steel silencer (TB) type


铂莱娱乐场To suppress the noise emitted by high-pressure steam flow, there are already various forms of stainless steel silencers that use throttling and pressure reduction. Due to their complex structure, large quantity, and difficulty in disassembly and repair, their application scope is limited. The stainless steel muffler of this type of structure overcomes the above shortcomings. This type of exhaust stainless steel muffler is designed in accordance with a reasonable sound reduction principle. High pressure steam enters the pressure reducing body through a large volume expansion after passing through a controlled flow in the exhaust stainless steel muffler, forming low-pressure steam that is then sprayed out. During this process, the internal energy of the steam flow is partially converted into sound energy of a certain frequency. Although the noise power is greatly reduced, it often remains above the standard value due to reasons such as deviation from the design value of the exhaust. For this purpose, a double-layer junction sound barrier was designed outside the pressure reducing body, which is based on the spectrum of residual noise emitted by the pressure reducing body, to effectively absorb residual noise. After the user installs according to the requirements, the total noise reduction should reach 36-42 decibels.


2. Stainless steel silencer for steam safety door (TA type)


-As is well known, for the safety valves of boilers and other thermal devices, excessive noise should be avoided during steam exhaust, and the steam flow should be smoothly discharged. Therefore, the commonly seen sound-absorbing methods for throttling and small hole injection should not be used. This limitation is not only the difficulty in designing stainless steel silencers for safety doors, but also the reason for the poor sound-absorbing performance of stainless steel silencers for safety doors. The stainless steel muffler used for safety doors in this model also adopts the principle of resistance, spray, and resistance to noise reduction. It replaces the smaller diameter control hole with a large hole expansion, strengthening the resistance, spray, and resistance to noise reduction mechanism in structure, and achieving the desired sound reduction effect.


铂莱娱乐场3. Low pressure steam stainless steel muffler (TD type)


铂莱娱乐场Various industrial and mining enterprises use a large number of low-pressure boilers with a pressure of 01.3MPa and below, and there are also a large number of low-pressure thermal devices in the power plant thermal system, such as backpressure steam turbines, deaerators, auxiliary air heaters, steam turbine oil pumps, continuous boiler discharge, and periodic discharge expansion devices. The exhaust pipe of the above equipment requires a stainless steel muffler that is lightweight and easy to install. Our factory designs a series of useful deaerator, backpressure steam turbine, and other series for different noise reduction objects, which can meet the requirements of users. The above-mentioned exhaust stainless steel muffler can meet the requirements of the Industrial Enterprise Noise Hygiene Standard and has been applied internally. Used for N3 type steam turbine, 20T/H low-pressure boiler superheater steam discharge. The boiler pressure is 13at, with a evaporation rate of 20T/H and an exhaust capacity of 10T/H.


4. Backpressure steam turbine exhaust stainless steel muffler (TDb series)


5. High pressure deaerator exhaust stainless steel muffler (TDy)


铂莱娱乐场Steam stainless steel silencer -:


1. Large noise reduction, - fire exhaust noise reduction ≥ 42dBA, safety valve exhaust noise reduction ≥ 39dBA, fan noise reduction ≥ 28dBA, high-pressure deaerator noise reduction ≥ 35dBA


铂莱娱乐场2. Steam stainless steel muffler has a small volume, light weight, and convenient installation.


铂莱娱乐场3. Steam stainless steel silencers - types, including small hole type, through hole type, small hole with sound barrier type, through hole with sound barrier type.


铂莱娱乐场4. The steam stainless steel muffler can last for up to 30 years. The ZXP, ZXA, and GZF series steam stainless steel silencers produced by the factory can meet the noise reduction and noise reduction requirements of various parameter boiler exhaust to the air, safety valve exhaust, and boiler supply fan. They are also used for boiler steam emissions and other gas noise reduction emissions in industries such as petroleum, chemical, metallurgical, and textile, making them meet the noise standards of industrial enterprises.


Steam stainless steel silencer -:


铂莱娱乐场1. Adopting - noise reduction, with a large amount of noise reduction, the exhaust stainless steel muffler can reach 35-40 decibels; The safety valve stainless steel muffler can reach 25 decibels or more; The stainless steel muffler of the fan can reach 30-40 decibels or more.


2. Small in size, lightweight, easy to install, and easy to maintain.


3. The cylinder body is made of high-quality stainless steel, which has sufficient strength and corrosion resistance.


4. This series of steam stainless steel silencers can fix and absorb the vertical and horizontal thermal displacement of the exhaust pipeline, so that the exhaust pipeline is not subjected to additional loads due to the installation of stainless steel silencers, ensuring the safety of the exhaust pipeline under thermal energy operation. They are mainly used for noise reduction of equipment such as steam emissions from boilers and fans in power, chemical, metallurgical, mining, and textile industries.


铂莱娱乐场Steam stainless steel silencer - outlet:


铂莱娱乐场Steam stainless steel silencers are mainly used for noise reduction of boiler steam emissions and other gas emissions in industries such as power, petroleum, chemical, metallurgy, and textile. It is an important measure to eliminate steam emissions and noise. Various types of boiler exhaust steam not only have high temperature and high pressure, but also discharge frequency bandwidth, which measures the damage of stainless steel silencers for steam emissions


The steam stainless steel muffler mainly considers the following three aspects:


1. The noise reduction capacity of stainless steel silencers for boiler steam can meet the requirements of the Industrial Enterprise Noise Standard.


2. Stainless steel silencers can adapt to different frequencies, high temperatures, and pressures (low high pressure, high pressure, subcritical, and critical).


铂莱娱乐场3. The structure of stainless steel muffler - (reasonable size, high strength, long length, easy installation). The steam stainless steel muffler is developed based on the principle of composite noise reduction with resistance, spray, and resistance. It has the advantages of large noise reduction, small volume, light weight, and easy installation.


铂莱娱乐场Working principle of steam stainless steel muffler:


The steam stainless steel muffler mainly adopts the principles of finite combination and internal absorption, completing the heat exchange between steam and the heated liquid inside. After passing through the stainless steel muffler, all steam is converted into hot water, avoiding strong vibration and noise caused by the free combination of steam and water (liquid) (such low-frequency vibration and strong noise can cause significant damage to equipment, buildings, and human health). After installing a static stainless steel muffler, the noise can be reduced to below 65 decibels, and external noise can be reduced to below 60-45 decibels depending on the situation, achieving non quiet results.


铂莱娱乐场The steam stainless steel muffler is mainly based on the theory of 银行卡small hole injection银行卡 combined with the principle of impedance expansion sound absorption. The boiler steam discharge has a general flow rate, high airflow noise, and needs to be expanded through a through-hole. After passing through a through-hole, the steam is depressurized and reduced in flow in the anti expansion chamber. The airflow is then sprayed out through a small hole, and the sound power of each octave band has been reduced after spraying, while the frequency of sound pressure is raised to above 20000Hz, greatly weakening the noise, However, some frequencies of secondary noise still need to be further silenced. We have installed a sound-absorbing cotton structure outside the expansion room, which is designed based on the spectrum of residual noise emitted by the pressure reducing body, to effectively absorb the residual noise. When the user installs according to the requirements, the noise reduction can reach 30-42 decibels. Make it meet the requirements of industrial enterprise noise standards.

铂莱娱乐场Example 4: TDb series: 银行卡TDb-5-20银行卡 type


Used for steam discharge during start-up and shutdown of low-pressure backpressure steam turbines, as well as manual control or safety door discharge during accident conditions. Exhaust pressure of 4-6 at and exhaust volume of 20T/H.


铂莱娱乐场The steam emissions of a back pressure steam turbine are divided into two categories: exhaust emissions and back pressure emissions. The one is superheated steam, with the word (over) marked after the model, while the latter can basically be regarded as saturated steam, with the word (full) marked after the model.


铂莱娱乐场Example 5: TDy series: 银行卡TDy-6-220/8银行卡 type


Used for the high-pressure deaerator of N50 type steam turbine - partial discharge steam - gas combination. Deaeration pressure of 6at, boiler evaporation of 220T


/H. The exhaust steam volume of the deaerator is 8T/H.


Instructions for ordering and selecting steam stainless steel silencers:


The exhaust stainless steel muffler series produced by our factory is designed according to the user's steam emission target and emission requirements. Therefore, only when the production meets the emission target, steam parameters, and emission amount can reasonable noise reduction results be achieved. Therefore, when ordering stainless steel silencers, the following parameters must be provided:


① For thermal power plants, the turbine model, boiler capacity, steam pressure, and temperature should be provided;


铂莱娱乐场② Object of use (such as for boiler overheat discharge or steam drum safety valve discharge, etc.);


③ Emissions T/H;


④ The original outer diameter and wall thickness of the exhaust pipe;


⑤ If it is necessary to commission our factory to carry out installation design, the original exhaust pipeline installation diagram should be provided.


For models not listed in the product manual, users can provide the relevant information mentioned above, and our factory will select them on their behalf.


铂莱娱乐场Installation instructions for steam stainless steel silencers:


铂莱娱乐场① The steam stainless steel muffler should be installed perpendicular to the factory building, as shown in Figure 3. The steam stainless steel muffler base should be fixed to the factory building using a steel bracket.


铂莱娱乐场② To increase the wind resistance of the factory building at high altitudes, the steam stainless steel muffler body adopts a supporting support. Therefore, the exhaust pipe of the steam stainless steel muffler should have an expansion bend to absorb heat expansion. If the original exhaust pipe has a drainage plate installed in the vertical direction, the expansion bend should be installed.


铂莱娱乐场③ The bottom of the steam stainless steel muffler body is designed with drainage pipes or drainage holes, and the holes should be checked to ensure they are unobstructed.


铂莱娱乐场④ The opening of the exhaust pipe passing through the factory building platform should have a rainproof cover made of thin steel plate (as shown in Figure 3).


⑤ For safety doors, in principle, only safety doors are equipped with stainless steel silencers. There are two types of safety doors: single seat and double seat. For double seat safety doors, the exhaust pipe can be merged into a main pipe and connected to the stainless steel silencer during installation. However, for double seat safety doors with large exhaust volume, two stainless steel silencers can also be installed.


⑥ For small displacement steam stainless steel silencers used for deaerator, steam jet extractor exhaust, etc., the external design is tubular, making installation more convenient. The installation method is shown in Figure 4, where the steam stainless steel muffler is installed vertically along the walls and columns of the main factory building. Install steel sliding brackets on walls and columns, and install steam stainless steel silencers and pipelines on them. The exhaust outlet of the steam stainless steel silencers should face the direction of the house. It should be noted that this type of steam stainless steel muffler is already equipped with a fixed support when leaving the factory. When using a sliding support installation, the fixed support can be omitted. As shown in Figure 4.
