With the rapid development of the power industry and the continuous expansion of power plant boiler units,300-1000MW units will become the main units in the future. Before the installation or restoration maintenance of thermal power generation units is completed and put into operation, in order to ensure the safe and economical operation of the units, steam blowing must be carried out to remove industrial waste such as rust, welding slag, and other debris inside the pipes of the superheater and reheater systems. To completely remove the debris inside the pipes, blowing can be carried out dozens or even hundreds of times, lasting for several days or longer. The powerful steam turbulence noise during pipe blowing is the aerodynamic noise with high sound level generated by high-speed airflow blowing out from the pipe mouth, impacting and shearing the surrounding static air, causing severe gas disturbance near the nozzle. The noise value generated is as high as 130dB (A) or above. The larger the unit capacity, the greater the aerodynamic noise generated. The jet noise is a continuous medium to high bandwidth noise, which seriously affects the life, work, and study of residents within a radius of more than ten square kilometers, especially causing serious harm to human physical and mental health. In order to eliminate the serious noise hazards caused by the unit blowing pipe, it is necessary to install a blowing pipe silencer at the end of the blowing pipe pipeline. The PG type power plant boiler blowing pipe muffler can be regarded as an integral part of the pipeline for pipe blowing. After acoustic treatment inside, it can reduce the generation and propagation of noise, and is an effective noise reduction device to solve the serious noise hazards caused by pipe blowing in the above-mentioned units.Boiler blowing in power plants is to eliminate impurities in the pipelinesandA quick method for dealing with engineering debris is to use a blowpipe muffler to meet the requirements of high temperature and high pressure steam during steam blowing of the unithaveAt the same time as silencing, it must also be reusable and ensure safety. To ensureblowpipeSilencers must be designed and meet strength requirements for safe useexpansionMeasures and requirements for displacement, drainage, rust allowance, and protection against block debris damage.Pipeline blowingThe quality of muffler manufacturing should be supervised and inspected by professionals from the design and regulatory agencies.
2、 Characteristics of blow pipe muffler:
1. The inlet part of the blow pipe muffler and the first stage throttle cylinder are made of alloy steel 12Cr1MoV, the second stage throttle cylinder is made of 1Cr18Ni9Ti, and the outer shell is made of 20g material.
2. Suitable for harsh working environments, the working medium may contain water, iron impurities (particle size up to)∮30mm）Engineering remnants.
3. The noise reduction can reach 20dB to 40 dB (A). Suitable for (blowing method): pressure stabilizing blowing tube, pressure reducing blowing tube, oxygen adding blowing tube.
4. When designing and manufacturing, it is necessary to refer to the technical regulations of GB150-1998 "Steel Pressure Vessels".
3、 Ordering parameters for blow pipe muffler：
