Steam emission muffler (XSQ-ZQ)

Steam emission mufflers are mainly used to reduce the noise emitted by steam emissions from thermal equipment such as steam boilers. This type of noise far exceeds the values specified in China's "Industrial Enterprise Noise Health Standards". The steam emission muffler produced by Glee has the advantages of large noise reduction, small size, light weight, and easy installation based on the principle of anti spray and resistance composite noise reduction. Mainly used for effective noise reduction of steam emissions from thermal equipment such as boilers and turbines in industrial sectors such as power generation, chemical, metallurgical, and textile industries. Its working principle is that high-temperature and high-pressure steam or low-pressure steam enters the muffler, undergoes primary expansion and pressure reduction, and then enters secondary pressure reduction. After large volume expansion and pressure reduction, low-pressure or ultra-low pressure steam is formed and sprayed out. Then, it passes through a composite structure of multiple materials to reduce noise again and is discharged into the atmosphere, thereby achieving the effect of noise reduction.

Classification of steam emission mufflers:

1. Steam safety valve silencer (ZA type)
Suitable for safety valves of power plant boilers (power release valves), drum safety valves, superheater safety valves, reheater safety valves and other pressure devices. The steam venting should not only avoid excessive noise, but also allow the steam flow to be smoothly discharged without affecting the displacement, jumping, and reseating of the safety valve. Therefore, the commonly used multi-stage throttling and small hole injection noise reduction methods in the past should not be used. This limitation has always been a design difficulty for safety valve mufflers and the reason for the poor noise reduction effect of safety door mufflers. The new type of safety valve exhaust muffler from Glee adopts a composite noise reduction principle of spray, resistance, and resistance. The larger hole expansion replaces the smaller diameter control hole, which further strengthens the resistance and resistance noise reduction mechanism in structure, achieving a more ideal noise reduction effect.
2. Low pressure steam muffler (ZD type)
Due to the use of a large number of low-pressure boilers with a capacity of 0.13Mpa and below in safety production by enterprises, there are also a large number of low-pressure thermal devices in the power plant thermal system, such as back pressure steam turbines, deaerators, auxiliary air extractors, steam turbine oil pumps, continuous and periodic boiler discharge, etc. According to the exhaust pipe requirements, the above equipment should be equipped with a lightweight structure and a more convenient installation muffler. Gree has designed specialized back pressure turbine exhaust silencers, deaerator silencers, and other series of noise reduction products for different noise reduction targets, which can meet the requirements of users.
3. Ignition exhaust muffler (ZP type)
The high-pressure steam formed by boiler ignition enters the pressure reducing body after a flow control in the muffler, and is further expanded and depressurized by a large volume to form low-pressure steam, which is then sprayed out. During this process, some of the internal energy in the steam flow is converted into sound energy of a certain frequency. Although the noise power is greatly reduced, the exhaust noise is often higher than the standard value due to various reasons such as deviation from the design value. For this purpose, a composite structure of multiple materials was designed as a sound blocking and absorbing cover outside the pressure reducing body. The composite sound blocking and absorbing cover is designed based on the spectral characteristics of the residual noise emitted by the pressure reducing body to effectively absorb the residual noise. After the user installs it as required, the total noise reduction can reach 36-42 decibels.
