Abstract
The utility model discloses a combined wet dust catcher, comprising a tower body, a pipeline, a blower, a water bath tank which is arranged in the tower from bottom to top, an air inlet pipe, two stories sieve plates, a spray shower head, a rotational flow plate and a clean shower head. The utility model has the advantages of simple structure, small occupation area, easy maintenance and no blocking. By testing, the dust concentration is from 10 grams / m+[3] to 45 grams / m+[3] which through primary treatment of the utility model all can reach national discharge standard of smoke and dust. The systemic resistance is from 90 mmh-[2]o to 130 mmh-[2]o, and water consumption of circulation is from 10 m+[3]/m+[2]h to 15 m+[3]/m+[2]h.
Description
The utility model relates to a kind of dust arrester in a kind of environmental protection smoke and dust treatment.Particularly a kind of combined wet scrubber.
Administering at present industrial fumes has multiple mode, and one of them is a wet dust removal, because wet dust removal has efficient height, simple in structure, advantage that maintenance cost is low, thereby is widely used.But existing wet scrubber generally is that a kind of deduster only adopts a kind of dust removal process method.For example: impact water bath formula deduster, be that the shower nozzle of dust-contained airflow through aiming at the water bath water surface sprayed at a high speed, flue dust is under the impact of the water surface, the part flue dust is hunted down because of the collision of inertia and water, foam that portion gas is then evoked and spray purify, its efficiency of dust collection is about 85%, and resistance is about 60～80mmH
2O.Also have gravity spraying and dedusting formula, it is when the liquid formed drop space of dusty gas by the shower nozzle ejection, and grit is collided, interception and cohesion, and lean on the gravity effect to settle down, together discharge with cleaning solution, its efficiency of dust collection is about 70%, and resistance is about 25mmH
2O has spray type sieve-plate tower deduster again, and the shower nozzle that it is installed by sieve plate and top thereof is formed, when dusty gas contacts with liquid on the plate by the sieve plate hole, form and spatter aqueous liquid layer, through the gas-liquid contact, flue dust is taken away by liquid, and its efficient is about 90%, and resistance is about 60mmH
2O, also has a kind of rotating stream tray scrubber formula in addition, it is the blind plate of liquid by the eddy flow plate to be assigned on each blade form liquid film, in the ascending motion of air-flow, liquid film is sprayed into drop, forms along the pendular ring of tower wall rotation, and adhered to the grit in the gas, finally be thrown toward the tower wall with the dirty discharge of liquid, its efficient is about 90%, and resistance is about 60mmH
2O.More than these several dedusters because all have only a kind of mode of dedusting, so only be applicable to the dust treatment of low concentration.For eliminating 10 gram/m
3During the flue dust of above high concentration, then must just can reach the standard-required of country through two stage treatment (promptly increasing one-level dry dust removal etc.) to soot emissions.Yet the use two-stage dust removal correspondingly will increase a large amount of equipment investments, and takies more place.
The purpose of this utility model is that proposition is a kind of with multiple wet scrubber structure, is combined into the technical scheme of a deduster, to realize eliminating with the primary dust removing device purpose of high concentration flue dust, overcomes weak point of the prior art.
The purpose of this utility model is to realize like this.
Combined wet scrubber is made up of water bath 1, sieve plate 4, eddy flow plate 6 and shower nozzle in tower body 3, pipeline 10, blower fan 12 tower bodies.Its feature is the bottom that the outlet of the water bath 1 and the air inlet pipe 2 of joining with the water bath water surface is positioned at tower body, and water bath one side has deltiod overfall 13; The two-layer sieve plate 4 that supports with gripper shoe is arranged on air inlet pipe, a spray nozzle 5 is arranged on sieve plate; An eddy flow plate 6 is arranged on shower nozzle; On the eddy flow plate, there is one to clean shower nozzle 7; Also has a pipeline rotational flow plate 9 in the exit of the elbow 8 that is connected with the tower body top.
Below in conjunction with drawings and Examples the utility model is described in detail.Fig. 1 is the schematic diagram of combined wet scrubber.
The plate thickness of combined wet scrubber is 6～8mm; The aperture is that φ 8.5mm percent opening is 30%～40%.
The eddy flow plate thickness 6～8mm of combined wet scrubber; The blade elevation angle is 25 °～30 °; The number of blade is 24, and percent opening is 30%.
The purification process of combined wet scrubber is: dusty gas at first enters impact water bath section in the tower by pipeline, the last water surface one side of water bath has the flat-square-shaped overfall, under leakage fluid dram is arranged, dust-laden liquid is mainly from leakage fluid dram discharge down, partially liq is discharged from overfall, and maintenance liquid level, after the water-bath section, dusty gas mixes with the foam liquid that splashes, gas further purifies, then gas passes through sieve plate, gravity sprays the liquid that gets off purifies gas again on sieve plate, then enter eddy flow plate 6 in the tower by spray section again, make liquid be thrown toward the tower wall with dirt and flow down along wall, last gas further separates gas-liquid through pipeline rotational flow plate 9 again.Dusty gas has reached the purpose of high-effective dust-removing by above these steps.In order to obtain moderate efficiency of dust collection and resistance, it is 8mm that this example is selected plate thickness, and the aperture is 8.5mm; Selecting the eddy flow plate thickness is 8mm, and the blade elevation angle is 27 °, and the number of blade is 24.According to the clean-up performance of recirculated water, shower nozzle 5 can be selected plate-making type or screw type or bowl-type shower nozzle for use.
The utlity model has following advantage:
1. the efficiency of dust collection height is processed the high concentration flue dust, and efficient can reach more than 98%; And resistance suitably is 90～13mmH2O, cycling use of water amount 10～15m3／m
2H gets final product. For example record in frying the test of oil machine tail gas clean-up: inlet concentration is 47.6 grams/mark, dried, rice3 Exit concentration is 0.2 gram/mark, dried, rice3 Processing tolerance is 2870 marks, dried, rice3/ hour; Recirculated water consumption 15m3／m
2, h; Resistance is 100mmH2O; Efficiency of dust collection reaches 99.6%.
2. deduster is simple in structure, takes up an area littlely, easy to maintenance, can not stop up.
