High performance deduster

Abstract

The invention provides a high performance deduster. The high performance deduster comprises an upper box body, the upper box body is provided with a seal cover, a lattice plate is arranged in the upper box body, a cavity between the seal cover and the lattice plate is a clean air cavity, dust-containing air cavities and a dust gravity settlement cavity are sequentially arranged at the lower portion of the clean air cavity, and clean air cavity sealing valves divide the clean air cavity into front clean air cavities and a rear clean air cavity; and a plurality of filter cylinder assemblies are arranged on the lattice plate, and are positioned in the dust-containing air cavity. The high performance deduster has the advantages of high dedusting rate, long service life and low cost.

Description

technical field [0001] The present invention relates to the field of improved filters and filtering methods specially used for separating dispersed particles from gases or vapours, in particular to a high performance dust collector. Background technique [0002] Industrial dust collection and dust purification mainly adopt filter bag filter and downflow filter cartridge filter. The filter bag dust collector uses needle-punched felt as the filter material. Due to the defects in the production of the filter material and the production method of the filter bag, the filtration accuracy of the filter bag is low. The filtration accuracy of the new filter bag is only about 90%. A layer of filter cake (dust layer) is formed on the surface, and the filtration accuracy of the filter bag can reach 99.9% only by the combination of filter material and filter cake. If the thickness of the filter cake is thin, the filtration accuracy cannot be achieved, and if the thickness of the filter ...

Problems solved by technology

[0005] 2. Due to the arrangement of the filter cartridge in the dust-laden gas chamber, the dust adsorbed in the downward folds of the upper filter cartridge flies to the lower part of the filter cartridge under the action of reverse air flow, and falls to the lower filter cartridge under the action of the dust particles’ own weight. Wrinkled upper surface, poor cleaning effect

[0007] 4. Due to the characteristics of the filter cartridge's own structure and the arrangement of the filter cartridge in the dusty gas chamber, the downflow filter cartridge dust collector is only suitable for filtering dust with large or small particle severity

Therefore, the sinking flow filter cartridge dust collector is more suitable for the dust generated in the mechanical casting sand cleaning process or the smoke generated in the tobacco processing process, and the purification effect for other industrial dust dust collection or smoke dust is poor

[0008] The dust filtration accuracy of the filter bag dust collector is low (about 98%), and it is not suitable for filtering dust or smoke with particles below 5 μm

Handling dust content 20g / m 3 The left and right flue gas must be used in series with two bag filter dust collectors to meet the dust emission concentration requirements stipulated by my country's current environmental protection standards. About 99.9%), but the purification effect of filtering industrial dust or smoke other than casting sand cleaning and tobacco treatment is poor, the scope of application is narrow, and the maintenance cost is high
