Correlative judgment method between the pressure change of the air distribution box and the working state of the pulse valve of the intelligent self-inspection and dust removal device

Abstract

The invention discloses an intelligent self-inspection dust removal device and a method for determining the correlation between the pressure change of the gas distribution box and the working state of the pulse valve. The pulse valve on the blowing pipe and the control unit for controlling the work of the bag filter, the gas distribution box pressure sensor for detecting the gas pressure in the gas distribution box, and the control unit includes a pressure sensor for recording the gas pressure on each blowing pipe. The signal collector of the opening and closing time of the pulse valve. Combined with the signals of the pressure sensor and the signal collector, the specific fault of the pulse valve assembly can be judged, and the fault information can be transmitted to the mobile terminal or computer, so that the operator or manager can know the working status of the bag filter in time.

Description

technical field [0001] The invention relates to an intelligent self-checking and dust-cleaning device and a method for determining the correlation between the pressure change of an air distribution box and the working state of an electromagnetic pulse valve. Background technique [0002] With the country's emphasis on air pollution control and the requirements for energy conservation and emission reduction, dust removal systems have been widely used in various industries. The bag filter is a dry dust filter device. After the filter material is used for a period of time, a layer of dust accumulates on the surface of the filter bag due to effects such as screening, collision, retention, diffusion, and static electricity. This layer of dust is called the first layer. During the subsequent movement, the first layer becomes The main filter layer of the filter material depends on the effect of the first layer, and the filter material with a larger mesh can also obtain higher filt...

AI Technical Summary

Problems solved by technology

The number of electromagnetic pulse valves has increased significantly with the increase in the size of the bag filter; at the same time, the injection sequence of the electromagnetic pulse valves is usually not arranged according to the natural sequence number, but a "jump" plus "discrete" arrangement, two adjacent The injection electromagnetic pulse valves are often far apart, and it is difficult to artificially perceive the injection situation of each electromagnetic pulse valve

The purpose of the present invention is to provide an intelligent detection method that can judge the working condition of the electromagnetic pulse valve according to the pressure change of the gas distribution box, and solve the difficult problem of manual inspection of the electromagnetic pulse valve
