Pipeline muffler is used to eliminate the noise generated by dynamic transmission, make gas and air flow through the pipeline, and prevent environmental noise from polluting human and livestock. The exhaust and vent system is composed of multi-stage different body, porous loose principle and metal sound-absorbing material.

Especially, it is widely used in chemical enterprises and thermal power plants. The structure of pipeline muffler is relatively compact. The muffler is made of stainless steel, which has the advantages of small volume, light weight, high strength and venting of the device;

Fixed separately, it can meet the requirements of thermal displacement of the pipe, at the same time, it can absorb the thermal displacement of vertical and horizontal exhaust pipe at the same time.

To ensure the safety of hot operation of exhaust pipe is an effective silencing equipment to control exhaust and vent noise. The muffler device does not affect the production of safety valve, the displacement of muffler and the jump of safety valve can also be quantitatively calculated in acoustics.

High temperature and high pressure steam and low pressure steam are used in the muffler to enter the secondary pressure reducing body after one-time capacity expansion and depressurization. The low-pressure steam or ultra-low-pressure steam is ejected through large capacity expansion and pressure reduction, and then it is combined with a multi-material composite structure sound barrier and sound-absorbing cover after one-time capacity expansion and pressure reduction, and then discharged into the atmosphere.

High temperature and high pressure steam and low pressure steam are used in the muffler after one-time capacity expansion and pressure reduction, and then enter the secondary pressure reducing body. After the large capacity expansion muffler is refitted to depressurize, the low-pressure or ultra-low-pressure steam is formed. After the muffler is ejected, the multi-material composite structure sound-absorbing cover outside the muffler is expanded and depressurized once again, and then discharged into the atmosphere.

The utility model has the advantages of high safety coefficient, large noise reduction value, small equipment size, light weight, convenient installation, etc., and can be used for industrial noise reduction.

According to the principle of large orifice jet type depressurization and noise elimination, after optimization design, the noise reduction index, safety performance and service life of the boiler are much better than those of the similar products on the market. It can better meet the requirements of industrial low pressure, medium pressure, sub high pressure, high pressure, ultra-high pressure, subcritical and other parameters of boilers, the discharge of exhaust gas from pressure vessels and their safety valves, and the noise reduction requirements of boiler exhaust gas 。

Boiler small hole muffler, also known as small hole muffler, its sound elimination principle is: under the condition of maintaining the same exhaust volume, many small holes are used to replace a larger nozzle, so as to make the high frequency sound move to the ultrasonic area which is not sensitive to human ears, so as to achieve the purpose of reducing noise.
