Intelligent deashing ash-discharging system for cartridge filter

Abstract

The invention discloses an intelligent deashing ash-discharging system for a cartridge filter. The intelligent deashing ash-discharging system comprises a high-pressure air pocket (1), a pressure difference control system (2), a pulse-jet control system (3), a pulse-jet system (4), a deashing ash-discharging system (5) and a dust collector box (6), wherein the high-pressure air pocket is used forrespectively supplying air to the pulse-jet control system, the pulse-jet system and the deashing ash-discharging system through the pressure difference control system. According to the invention, thehigh-pressure air pocket can be opened / closed by the pressure difference control system according to the condition of cartridge dust deposition, so as to control the running of the whole system; pulse valves are opened / closed in turn by the pulse-jet control system; the pulse-jet system is used for realizing jetting and deashing of cartridges in turn; the deashing ash-discharging system is used for discharging ash out of the cartridge filter; all the systems cooperatively work, so as to finish intelligent deashing for a plurality of cartridges in turn. The intelligent deashing ash-dischargingsystem for the cartridge filter has the advantages of excellent sealing property, less space usage, simple structure, convenience in operation and suitability for deashing system of various dry cartridge filters.

Description

technical field [0001] The invention belongs to the technical field of dust removal devices, and in particular relates to an intelligent dust removal system for a filter cartridge dust collector. Background technique [0002] Cartridge dust collector is a high-efficiency dust removal equipment widely used in mines, tunnel excavation and chemical industry. It intercepts the dust in the dusty gas through the interception of the filter cartridge, so that the gas passing through the filter cartridge can be purified, and it can be used for operation. Provide a clean working environment for personnel. The dust removal system is the main component of the filter cartridge dust collector, which directly affects the performance of the dust collector. At present, for some workplaces with low electrical explosion-proof requirements, an automatic ash removal system composed of PLC, electromagnetic pulse valve, screw ash unloading valve and other electrical equipment is generally used; b...

AI Technical Summary

Problems solved by technology

At present, for some workplaces with low electrical explosion-proof requirements, an automatic ash removal system composed of PLC, electromagnetic pulse valve, screw ash unloading valve and other electrical equipment is generally used; but for mines, tunnels and other working environments where there is gas In gas workplaces, the risk of gas explosion is high, and there are potential safety hazards in the use of electrical equipment. Therefore, the relatively backward manual cleaning method is still generally used at present, which is time-consuming and laborious, and there are problems of untimely and incomplete cleaning. Seriously affect the use effect of the dust collector

[0003] When the filter cartridge dust collector is cleaning dust, since the amount of compressed air stored in the high-pressure air bag is limited, and the number of filter cartridges that need to be cleaned is relatively large, if all the filter cartridges are cleaned at the same time in an instant, it will inevitably cause high-pressure air. The compressed air supply in the bag is insufficient, so that the amount of dust removal air that can be distributed by a single filter cartridge is relatively small, and it is difficult to meet the needs of filter cartridge dust removal
