One.blowpipe muffler
With the rapid development of power industry and the increasing number of boiler units in power plants, 300-1000MW units will become the main unit in the future. Before the thermal units are installed or restored and put into operation, in order to ensure the safe and economic operation of the units, steam blowing must be carried out to remove the rust, welding slag and other industrial wastes in the pipes of superheater and reheater systems. In order to completely remove the impurities in the pipeline system, the number of pipe blowing is as many as dozens or even hundreds, and it lasts for several days or longer.
When blowing a pipe, the powerful steam turbulence noise is the aerodynamic noise with high sound level caused by the high-speed air jet from the nozzle, which impacts and shears the surrounding static air, causing severe gas disturbance near the nozzle. The noise value is as high as 130dB(A) and above.

The complexity of the blowpipe pipeline makes it a complicated problem to determine the steam parameters in the pipeline system. In addition, the steam velocity in the pipeline is very high, and the high-speed airflow contains a lot of rust, welding slag and other industrial garbage. In order to achieve a certain noise reduction effect, the design and manufacture of the muffler are required.
After years of research and practical production experience, the blow pipe muffler produced by our company is a mature product and has obtained the national patent (patent number; 201520536437.7).
It can withstand the violent impact of various industrial wastes and discharge them smoothly.

FOUR. Introduction of Box Blowpipe (JSTX) Muffler
Box-type blow pipe muffler is a patented muffler developed by our company (patent number; 201520536437.7), based on the tubular muffler, the second-stage muffler and the upper muffler fence are added, and a layer of shell is added, which not only improves the muffler effect, but also greatly improves the safety performance of the muffler. Principle: After the steam passes through the flow control and pressure control, it is depressurized by the internal secondary muffler, and a plurality of air streams are effectively silenced by the side sound absorption device.It is suitable for places with high requirements for sound elimination effect of blowing pipe.
Advantages:
(1) Good noise elimination effect;
(2) Low resistance and high safety.
(3) Convenient installation and long service life.
