Rotating filter cartridge dust remover with ashing suction nozzle

Abstract

The invention relates to the technology of dust removal of industrial gases and recycling of particles, comprising a shell body of a dust collector, a gas distributor arranged in the shell body, a filter cylinder, a diaphragm, sealing parts of the diaphragm and the filter cylinder, an ash removal suction mouth positioned at the lateral side of the rotating filter cylinder, and an air outlet, a directional valve and an external dust removal gas dust collector that are sequentially connected together. The invention is characterized in that the filter cylinder is a rotating filter and provided with a filter cylinder rotation mechanism which is connected with the filter cylinder; the gas distributor, the suction mouth, the sealing parts of the diaphragm and the rotating filter cylinder and the air outlet are fixed. Or the filter cylinder is fixed and the suction mouth rotates in the filter cylinder. The suction dust removal can be divided into a single segment or a plurality of segments according to the length of the filter cylinder so as to form a suction mouth or a plurality of suction mouths of cyclic suction. The invention separates the filtration process of the dust collector from the dust removal process of the dust collection, which improves the reliability of the dust removal equipment, filters the gas with dusts continually and stably, collects dusts together and simplifies the operation process of the equipment.

Description

technical field [0001] The invention relates to the technology of industrial gas dust removal, in particular to a rotary filter cartridge dust collector with multi-stage suction nozzles for dust removal. Background technique [0002] Industrial gas dust removal can be divided into high-temperature dust removal and low-temperature dust removal. The methods include: cyclone dust removal (single-tube, multi-tube), wet dust removal, bag dust removal, electrostatic dust removal and granular layer dust collector. Due to the limitation of the dust removal principle, the dust-containing gas after dust removal by the cyclone dust collector cannot meet the dust removal requirements of the process or meet the discharge requirements in some occasions; the electrostatic precipitator has special requirements for dust characteristics, gas temperature and moisture content; bag dust collector In addition to the requirements on the temperature and humidity of the dust-laden gas, the bag in th...

AI Technical Summary

Problems solved by technology

Due to the limitations of the dust removal method (air knife dust removal) and the internal dust removal structure of the existing filter cartridge dust collector, the operational performance of the dust collector is affected: the dust removal performance is reduced, the gas processing capacity is reduced, and the reliability of the dust discharge mechanism is poor

Because, the air knife dust cleaning is that the high-pressure gas forms a tangential air knife airflow on the surface of the filter cartridge (two filter cartridges in one set), and the dust on the surface of the filter cartridge is entrained. After the entrained dust leaves the surface of the filter cartridge, it is large and heavy. The particles fall into the bottom of the dust collector under the action of gravity, and the rest of the small and light particles are still wandering in the dust collector. The initial concentration of the airflow is artificially increased. Even if the dust removal efficiency is improved, the emission concentration of the airflow will also increase significantly; The amount of ash gas is large (and changes with the length of the filter cartridge), resulting in a decrease in the effective processing capacity of the dust collector; in addition, the dust collector works under negative pressure, and the unsealed ash discharge mechanism of the dust collector makes it difficult to discharge ash. Long-term operation affects the equipment. The reliability of the filter cartridge is driven by the purified airflow, but the speed cannot be controlled, the reliability is poor, and the rotation speed cannot be adjusted to achieve the purpose of controlling the dust removal efficiency
