Pulse valve performance detecting device and method

Abstract

The invention relates to a impulse valve impulse valve detection device and method, whose apparatus is consisted of air compressor, air container, water-oil separator, pressure reducing valve, voltagestabilizing air pocket, inspected pulse valve, blowing pipe, pressure sensor, target, acceleration transducer, data collection card and computer and, detecting and measuring acceleration and voltagestabilizing air pocket of impulse valve by measuring pressure of shell of pipe of blowing pipe, acceleration created by target and pressure change of voltagestabilizing air pocket property. The content tested by the invention is overall, complete, with good versatility, which can supply scientific foundation for designing and choosing impulse valve, avoiding economic lose caused by incorrect choice and doing good to impulse bag dust catcher reaching the best effect of ash removal.

Description

1. Technical field [0001] The invention relates to a performance detection device for a pulse valve and a method for detecting the performance of a pulse valve using the device. The pulse valve of the present invention is a diaphragm valve for rapid release of compressed gas used in environmental protection for pulse jet cleaning of bag filters. powered off. 2. Technical background [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...

AI Technical Summary

Problems solved by technology

There are significant differences in the injection performance of different structures and models of pulse valves. At present, there are many types 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. Lack of reliable pulse valve performance evaluation means and devices, it is difficult to accurately and quantitatively provide pulse valve performance parameters

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
