The detection device is used for detecting performance of pulse valve

Abstract

The invention discloses a detection device for detecting the performance of a pulse valve, and the device comprises four parts: a compressed air supply part, a pulse blowing part, a blowing airflow data collection part, and a data processing part, and the compressed air supply part consists of an air compressor, an air storage tank, a separator, and a pressure reducing valve. The pulse injection is composed of a pressure stabilizing air pocket, a detected pulse valve and an injection pipe; the blowing airflow data acquisition unit is composed of a pressure sensor, a target, an acceleration sensor and a data acquisition unit; the data processing is composed of a microcomputer controller; an air compressor, an air storage tank, a separator and a pressure stabilizing air pocket are connectedthrough an air compressing pipeline, and a pressure reducing valve is arranged on the pipeline between the separator and the pressure stabilizing air pocket. The detection content is comprehensive, complete and good in universality; the test result is accurate, stable and reliable, the operation is convenient, and the performance test, result comparison and evaluation of pulse valves of differenttypes, different structures and different sizes can be met.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for detecting the performance of a pulse valve. Background technique [0002] The bag filter is a kind of dust removal equipment that uses the filter bag made of filter cloth to filter and separate the dust in the dusty gas. It has two basic working states of filtering and dust removal. During filtration, dust is collected on the outer surface of the filter bag, and after the filtration resistance gradually increases to a certain value, it needs to be cleaned to maintain the continuous filtration capacity of the dust collector. A common and effective way of dust removal is pulse jet dust removal, that is, the compressed gas in the air bag is quickly released into the inner cavity of the filter bag by using the pulse valve to quickly open and close, and the instantaneous swelling deformation of the filter bag makes the surface of the filter bag The dust filter cake falls o...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many varieties of pulse valves on the market, with different calibers and structures. The performance parameters of pulse valves can only be estimated according to the field use effect. The lack of reliable pulse valve performance evaluation methods and devices makes it difficult to accurately and Quantitatively provide the performance parameters of the pulse valve

Therefore, in the face of many pulse valves of different sizes, structures, and manufacturers, designers have a certain degree of blindness in the configuration design of the dust removal system and the selection of operating parameters, which often results in abnormal operation of the equipment and poor dust removal effect. , waste of investment, high energy consumption for cleaning

Due to insufficient understanding of the performance parameters of the pulse valve, users also encounter obstacles in the use and management of dust removal equipment
