Nitrogen generator silencer

Abstract

The invention discloses a silencer for a nitrogen generator. The silencer for a nitrogen generator comprises a casing and an air inlet pipe and an air outlet pipe arranged inside the casing. An air inlet is arranged on the upper end surface of the casing. The air pipe is connected, and the lower end surface of the shell is provided with an air outlet mesh port, and the air outlet mesh port is connected with the air outlet pipe, and an air inlet through hole is opened on the side wall of the air inlet pipe, and an air outlet through hole is opened on the side wall of the air outlet pipe , and the air inlet through hole communicates with the air outlet through hole. The invention relates to a silencer for a nitrogen generator, which has the advantages of simple structure, low cost, good noise reduction effect, and at the same time helps to improve the production efficiency of the nitrogen generator.

Description

technical field [0001] The invention relates to a muffler, in particular to a muffler for a nitrogen generator. Background technique [0002] In my country, industrial gas equipment has developed rapidly and has been widely used in metallurgy, petrochemical, fertilizer, city gas, machinery, electronics, glass, chemical fiber and other industries. [0003] During the operation of the nitrogen generator adsorber, the gas discharged from the adsorber has a certain pressure, and when it is discharged through the exhaust valve, it will generate a lot of noise, causing noise pollution in the working environment. [0004] However, the traditional nitrogen generator silencer has the following problems: [0005] 1. The traditional muffler is bulky and heavy, requires a lot of steel, is expensive, and is not easy to repair and maintain; [0006] 2. The noise of the traditional muffler is still very loud, and the noise of using the traditional muffler when the nitrogen generator is v...

AI Technical Summary

Problems solved by technology

[0005] 1. The traditional muffler is bulky and heavy, requires a lot of steel, is expensive, and is not easy to repair and maintain;

[0006] 2. The noise of the traditional muffler is still very loud, and the noise of using the traditional muffler when the nitrogen generator is vented is about 90db or more;

[0007] 3. The interior of the traditional muffler is filled with silencer cotton and other materials, resulting in large venting resistance of the nitrogen generator, slow venting, and incomplete discharge, which is not conducive to the improvement of the nitrogen production capacity of the nitrogen generator
