Problems solved by technology

[0004] The complexity of the blowpipe pipe makes it a complicated problem to determine the steam parameters in the pipe system. In addition, the steam flow rate in the pipe is very high, and the high-speed steam flow is mixed with a large amount of industrial waste such as scale, welding slag, and other sundries. To achieve a certain noise reduction effect, the design and manufacture of the muffler is very high
[0005] Although the existing muffler can reduce noise, its noise reduction effect is not ideal, and its noise reduction status cannot be observed. Under the violent impact of various industrial waste, its own structure absorbs the problem of thermal expansion and contraction caused by high temperature. Cause the muffler to be deformed or even damaged, and the service life is short

Embodiment

[0024] The blowpipe muffler is generally installed in an outdoor open area. The inlet connecting pipe 1 is connected to the incoming steam pipe. The muffler support 9 is placed flat on the prefabricated cement on the flat ground. The support 9 and the platform generally do not need to be fixed forcibly, allowing the muffler to expand freely. The four corners of the upper part of the muffler are fixed on the surrounding ground anchors or counterweights with pulleys.

[0025] After each use of the muffler, the internal sundries must be cleaned up, especially the sundries in the round hole of the main pipe. The sundries in the outer muffler chamber can be cleaned through the sundry observation hole 12 with a small tool to eliminate the noise. The debris on the chamber 10 holes must also be cleaned up for safe use next time.

[0026] After the muffler is used every time, the 5 end of the muffler with head can be raised, so that the water collected inside the muffler will be discha...

Abstract

The invention discloses a pipe blowing silencer. The pipe blowing silencer comprises a silencer shell, wherein an inlet connection tube is arranged at the left end of the silencer shell; a debris discharge observation hole is formed below the inlet connection tube; the right end of the silencer shell is provided with a shell cover; a main pipe debris discharge opening is arranged below the shell cover; two ends of the bottom of the silencer shell are provided with pedestals; silencer debris discharge openings and water drainage ports are arranged at the middle part of the bottom of the silencer shell; silencing chambers are arranged in the silencer shell; and an upper cover plate is arranged on the upper part of the silencer shell. According to the pipe blowing silencer, debris in the silencing chambers can be cleaned through the debris discharge observation hole; the debris can be effectively removed; and reusing of the next time is facilitated, so that noise reduction can be realized better.

Description

technical field [0001] The invention relates to the field of boiler noise reduction equipment, in particular to a blowpipe muffler. Background technique [0002] With the rapid development of the electric power industry, the boiler units of power plants continue to increase, and the 300-1000MW units will become the main units in the future. In order to ensure the safe and economical operation of the thermal power generation unit after installation or restorative maintenance and before it is put into operation, steam blowing must be carried out to remove scale, welding slag and other sundries inside the pipes of the superheater and reheater systems, etc. Garbage, in order to completely remove the sundries in the piping system, blow the pipe dozens or even hundreds of times, and last for several days or longer. When blowing the pipe, the powerful steam turbulence noise is the high-level aerodynamic noise generated by the high-speed airflow ejected from the nozzle, impacting a...
