A single-fan dust absorption purifier and its absorption and purification method

Abstract

The invention discloses a single-fan dust absorption purifier and an absorption purification method thereof, belonging to the technical field of industrial dust removal and purification. The present invention includes a dust absorption mechanism and a dust purification mechanism. The dust absorption mechanism includes a fan, and the fan absorbs and transports the dust to the dust purification mechanism. The dust purification mechanism includes a clean room, a first recoil device and a second recoil device. A recoiler is located inside the clean room, and the bottom of the first recoiler is connected to the clean room. The above-mentioned fan transports the dust to the purification liquid inside the first recoiler, and the dust is repeatedly discharged through the second recoiler. There is a gap between the outer periphery of the second recoiler and the periphery of the purification chamber in the purified liquid delivered to the interior of the first recoiler. The present invention utilizes the combined effect of the first recoiler and the second recoiler on the dust, so that the dust can be repeatedly absorbed and purified by the purification liquid in the purification chamber, which greatly improves the efficiency of dust absorption and purification, and has low maintenance cost and simple structure. Easy 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.
