Description
Technical Field
[0001] The utility model belongs to the technical field of chemical silencers, and in particular relates to a simple medium-pressure steam purge silencer. Background Art
[0002] In the synthetic ammonia process, silencers are mainly used in various steam venting pipelines. Their main function is to reduce the noise pollution generated during the steam venting process.
[0003] After the construction of the chemical plant is completed, the steam pipeline needs to be purged to ensure that there are no impurities, rust and other substances in the steam pipeline to ensure the safe operation of the turbine pump. During the steam purging process, the noise pollution generated is large, which is easy to affect the on-site operation communication and the living environment of the surrounding residents. Therefore, during steam purging, a steam purging silencer must be installed in accordance with the requirements of the competent department and the company. Because there are multiple steam purging ports in the device, multiple silencers need to be installed, which greatly increases the construction cost. Summary of the invention
[0004] In view of the above problems of high purge noise, many impurities and high cost, the utility model provides a simple medium-pressure steam purge silencer, and its technical solution is as follows:
[0005] A medium-pressure steam purge silencer comprises an inner cylinder arranged inside an outer cylinder, the inner cylinder and the outer cylinder are arranged concentrically to form a surrounding annular gap, the bottom of the inner cylinder is connected to the bottom of the outer cylinder, a lower mesh grille is arranged at the upper position of the outer cylinder to seal the inner cylinder, the upper part of the lower mesh grille is filled with fillers, the upper part of the bulk fillers is paved with multiple layers of screens, and the upper mesh grille is arranged on the screen.
[0006] A medium-pressure steam inlet pipe and a drain port are arranged at the bottom center of the outer cylinder, and a steam outlet is arranged at the top.
[0007] A drainage port is arranged at the bottom of the outer cylinder, and an opening is also arranged at the bottom of the annular gap of the cylinder.
[0008] The middle wall of the inner cylinder is porous, the hole specification is 5-8mm round hole, and the number of holes is equal to the cross-sectional area of the inlet pipe / total hole area, so as to achieve the purpose of pressure reduction and silencing.
[0009] The inner cylinder and the outer cylinder are concentrically arranged, and the surrounding annular gaps are evenly arranged, so as to ensure that the inner cylinder and the outer cylinder of the equipment are evenly stressed and prevent the cylinder from being damaged by high temperature stress changes.
[0010] The mesh number of the sieve is smaller than the average size of the bulk filler, and the sieve is laid in 3-5 layers and is resistant to high temperatures.
[0011] The legs are evenly arranged on the outer wall of the lower part of the outer cylinder and form an equal triangle of 120° for fixing the medium-pressure steam purge silencer.
[0012] The bulk filler filling thickness should achieve the purpose of noise reduction.
[0013] Beneficial effects of the utility model:
[0014] 1. Effectively reduce the noise hazard caused by medium-pressure steam purging;
[0015] 2. Effectively prevent the damage caused by splashing of rust residues generated by the purging of medium-pressure steam pipelines;
[0016] 3. Effectively prevents condensate shock caused by medium-pressure steam impact condensation.
[0017] 4. The medium-pressure steam purge silencer is made of local materials, including the inner and outer cylinders, legs, bulk fillers and upper and lower grilles, which reduces procurement and construction costs, reduces noise and achieves the purpose of waste recycling.
