Problems solved by technology

The application uses the recoil device to solve how to make the welding fume easily enter and stay in the purification liquid in the clean room, and then through the recoil device on the purification liquid, the dry smoke is absorbed and purified repeatedly, thereby improving the absorption of welding fume The efficiency of 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 welding fume absorption purifier solves how to make it enter the purification liquid. For large particles such as dust, 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. Only a high-power fan can ensure the absorption effect, but a large-power fan makes the dust leave quickly after contacting the atomized purification liquid, resulting in too short a contact time to ensure the absorption effect, especially the contact area of ​​the dust gas with a large concentration is not enough Further reduce the absorption efficiency, and the filter, steel ball and sponge block at the upper end of the outlet pipe need to be replaced frequently, which will increase the purification cost virtually

Embodiment 1

[0038] combine figure 1 and figure 2 , a dual-fan dust absorption purifier in this embodiment can not only absorb and purify dust, but also absorb odors. The dual-fan dust absorption purifier includes a dust absorption mechanism and a dust purification mechanism. The dust absorption mechanism is used to absorb dust And delivered to the dust purification mechanism, the dust absorption mechanism includes a dust cover 13, a dust suction hose 14, a fan inlet pipe 15, a first fan outlet duct 12-1 and a second fan outlet duct 12-2, The first fan 11-1 and the second fan 11-2 (such as figure 2 shown), the first blower 11-1 and the second blower 11-2 absorb the dust and transport it to the dust purification mechanism, the dust suction cover 13 is connected with the blower air inlet pipe 15 through the dust suction hose 14, and the blower intake The air duct 15 is in a "U" shape, and the fan suction port of the first fan 11-1 communicates with one end of the fan inlet pipe 15, and t...

Embodiment 2

[0048] A dual-fan welding fume absorption purifier in the comparison patent is used to absorb and purify the dust, and the test is carried out in the workshop. The test environment conditions are: temperature 12 ° C, humidity 35% rh, the specific instructions are as follows: 1# sampling position is not In the dust absorption workshop, the average height of the operators is 1.7m, the height of the mouth, nose and other respiratory organs from the ground is 1.5m, and the total dust concentration is 150mg / m 3 ; In the workshop for dust absorption at the 2# sampling position, the average height of the operators is 1.7m, the height of the mouth and nose and other respiratory organs from the ground is 1.5m, and the dust concentration at the smoke hood of the dry smoke absorption purifier is 150mg / m 3 , the dust concentration outside the filter at the upper end of the outlet pipe of the dry smoke absorption purifier is 30mg / m 3 ; In the workshop after dust absorption at the 3# sampli...

Abstract

The invention discloses a dual-fan dust absorption purifier and an absorption and 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 first blower fan and a second blower fan. The first blower fan and the second blower blower absorb and transport the dust to the dust purification mechanism. The dust purification mechanism includes a clean room and a second blower fan. A recoiler and a second recoiler, the bottom of the first recoiler communicates with the clean room, the above-mentioned first fan and the second fan convey the dust to the purification liquid inside the first recoiler, through the second recoiler The second recoiler repeatedly conveys the dust to the purification liquid inside the first recoiler, and there is a gap between the outer periphery of the second recoiler and the periphery of the purification room. 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 relates to the technical field of industrial dust removal and purification, and more specifically relates to a dual-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 the ...
