Single-fan dust absorbing purifier and absorbing and purifying method of single-fan dust absorbing purifier

Abstract

The invention discloses a single-fan dust absorbing purifier and an absorbing and purifying method of the single-fan dust absorbing purifier and belongs to the technical field of industrial dedusting and purifying. The single-fan dust absorbing purifier comprises a dust absorbing mechanism and a dust purifying mechanism, the dust absorbing mechanism comprises a fan, the fan absorbs dust and delivers the 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, a gap is formed between the periphery of the second backflush device and the periphery of the purifying chamber, and the dust is delivered into purifying liquid in the first backflush device via the fan and delivered into the purifying liquid in the first backflush device repeatedly via the second backflush device. The single-fan dust absorbing purifier and the absorbing and purifying method of the single-fan dust absorbing purifier have the advantages that through combined action of the first backflush device and the second backflush device, the dust can be absorbed and purified by the purifying liquid in the purifying chamber repeatedly, so that dust absorbing and purifying efficiency is improved greatly, and the single-fan dust absorbing purifier is low in maintenance cost, simple in structure and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of industrial dust removal and purification, and more specifically relates to a single-fan dust absorption purifier and an absorption and purification method thereof. Background technique [0002] 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 difficulty in breathing. It can cause pneumoconiosis in the long run and cause short-term and long-term harm to people. Therefore, dust must be controlled to prevent it from polluting the environment and endangering human health. [0003] Existing dust purifiers generally adopt a circuitous air path to achieve th...

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.
