An integrated control system and method for mine dry dust collector

Abstract

The invention discloses an integrated control system and an integrated control method for a mining dry dust remover. An air inlet device is arranged on one side of a dry dust removal box, a connecting cylinder, a fan and an integrated controller are sequentially connected to the other side of the dry dust removal box, a dust discharging box is arranged at the bottom of the dry dust removal box, and a filter cartridge is arranged in the dry dust removal box, wherein a pulse valve is connected to the upper part of the filter cartridge in the dry dust removal box; a blowing controller is connected to the upper end of the pulse valve; a dust concentration sensor is arranged at an inlet of the air inlet device; an air speed sensor is arranged at an outlet of the dry dust removal box; a frequency converter is arranged on the fan; the blowing controller is connected with the pulse valve; the dust concentration sensor and the air speed sensor are connected with the integrated controller through a wire, and transmits monitoring data to the integrated controller in real time. The system and the method have the advantages that the frequency of the fan can be automatically adjusted according to the dust concentration of an underground dust production operating site, the dust suction air inflow is optimized, and whether blowing dust removal operation is started is analyzed according to the air speed of the outlet of the dry dust removal box, so that the dust filtering efficiency of the filter cartridge is improved.

Description

technical field [0001] The invention relates to an integrated control system of a dust collector, in particular to an integrated control system and a method for a mine dry dust collector. Background technique [0002] The annual death cases of pneumoconiosis in my country's coal industry have exceeded twice that of production safety accidents. The westward shift of coal mining strategy is the general trend, and the contradiction between the increase of mine dust intensity and the drought and water shortage in the west has become increasingly prominent. Dust control is transforming from wet method to dry method. For this reason, engineers and technicians in this field have designed "explosion-proof dust collector for mine" (ZL201010248827.6) and a mobile jet filter cartridge dust collector (ZL201110183007.8). In the mine explosion-proof dust collector, the filter cartridge is used to filter the dust and the dust is cleaned manually by pulse jet, which requires manual operat...

AI Technical Summary

Problems solved by technology

The mine explosion-proof dust collector uses a filter cartridge to filter the dust and then manually pulses the dust to clean it. It requires manual operation, which is time-consuming and laborious.

A mobile jet filter cartridge dust collector adopts a mobile jet to remove dust after filtering dust in the filter cartridge. Although it has a control system to control the injection of the mobile pulse valve, but in what state the filter cartridge is in the state, the pulse valve will spray , could not specify
