Absorbing and purifying method for single-fan dust absorbing purifier

Abstract

The invention discloses an absorbing and purifying method for a single-fan dust absorbing purifier, and belongs to the technical field of industrial dust removal and purification. The single-fan dust absorbing purifier comprises a dust absorbing mechanism and a dust purifying mechanism, wherein the dust absorbing mechanism comprises a fan; the fan is used for absorbing and conveying dust to the dust purifying mechanism; the dust purifying mechanism comprises a purifying chamber, a first backflush device and a second backflush device; the first backflush device is positioned inside the purifying chamber; the bottom of the first backflush device is communicated with the purifying chamber; the fan is used for conveying the dust into purification liquid inside the first backflush device; dust is repeatedly conveyed into the purification liquid inside the first backflush device through the second backflush device; gaps are formed in the outer periphery of the second backflush device and the periphery of the purifying chamber. Under the coaction of the first backflush device and the second backflush device on the dust, the dust can be repeatedly absorbed and purified by the purification liquid in the purifying chamber, so that the dust absorbing and purifying efficiency is increased greatly; moreover, the single-fan dust absorbing purifier is low in maintenance cost, is simple in structure, and is convenient to use.

Description

[0001] The patent application of the present invention is a divisional application with application number: 2015102993719. The application date of the original application is: June 3, 2015. The name of the invention is: a single-fan dust absorption purifier and its absorption and purification method. technical field [0002] The invention belongs to the technical field of industrial dust removal and purification, and more specifically relates to an absorption and purification method of a single fan dust absorption and purification device. Background technique [0003] In the mining industry, stone crushing industry, milling industry, power generation industry, smelting industry, chemical industry, and machinery manufacturing industry, a large amount of dust will be generated, which will seriously pollute the air, reduce the quality of life, and destroy the ecological environment. Working under the environment is likely to lead to narrow airway, reduced lung capacity, or diffi...

Problems solved by technology

This application uses the recoiler to solve how to make the welding fume easily enter and stay in the purification liquid in the clean room, and then through the action of the recoiler on the purification liquid, the dry smoke is absorbed and purified, thereby improving the efficiency of welding fume absorption and purification , but if the welding fume absorption purifier is used to absorb and purify dust, its shortcomings are obvious. The particles of welding fume are small. The solution of the welding fume absorption purifier is how to make it enter the purification liquid. For large particles, the problem to be solved is not only how to enter the purification solution, but the technical difficulty is how to ensure its purification effect in the atomized purification solution, and because the dust particles are larger and heavier, a larger power filter is required. The fan can ensure the absorption effect, but the larger power fan makes the dust leave quickly after contacting the atomized purification liquid, resulting in too short contact time to ensure the absorption effect, especially the contact area of ​​the dust gas with a large concentration is not enough to further reduce The absorption efficiency is high, and the filter, steel wool and sponge block at the upper end of the outlet pipe need to be replaced frequently, which will increase the purification cost virtually.
