Abstract

The utility model discloses a negative pressure-type wet dust collector, comprising a vertical washing tower and a fan, wherein the vertical washing tower is connected with the fan through a pipeline; the vertical washing tower is orderly provided with a plurality of whirlwind plates from top to bottom at intervals, so as to form a plurality of spraying zones; each spraying zone is provided with a shunt pipe; each shunt pipe is provided with a plurality of spray headers at intervals; the shunt pipe is connected with a pump through a battery tube; a demisting layer is arranged at the upper end of the vertical washing tower; an outfall is arranged at the lower end of the vertical washing tower; and the outfall is communicated with the water tank. By adopting the negative pressure-type wet dust collector, the vertical washing tower is divided into the plurality of spraying zones by the whirlwind plates to spray once; and the clean gas processed once is sprayed and washed for the second time through a second layer of the whirlwind plate, enters the fan through the demisting layer after being thoroughly washed, and is finally discharged. The destructive substances in the gas containing dust are prevented from directly damaging the fan in the process; and the service life of the fan is greatly prolonged.

Description

A kind of negative-pressure type wet scrubber
Technical field
The utility model relates to cleaner, particularly a kind of negative-pressure type wet scrubber.
Background technology
At present, wet scrubber generally adopts positive pressure type, the dusty gas that namely need process be after first being sucked by blower fan again air-out enter wet dedusting tower, carrying out the water spray processes, this is designed with following shortcoming: owing to containing a large amount of dust in dusty gas, simultaneously also with a certain amount of bulky grain thing, and the bulk object that causes because of improper use, or house refuse enters (having destructive material).At this moment, blower fan when carrying dusty gas to enter washer box, these dust, bulk object, and the direct shock impeller of blower of house refuse cause coup injury to fan blade.The long-term use causes blower fan to damage, and system can't normally move.
The utility model content
The purpose of this utility model is for the defects of prior art, to provide a kind of negative-pressure type wet scrubber.
for solving the above-mentioned deficiency of prior art, technical scheme to be solved in the utility model is: a kind of negative-pressure type wet scrubber, comprise a vertical scrubbing tower and a blower fan, vertical scrubbing tower is connected with blower and pipeline, described vertical scrubbing tower from top to bottom is interval with the polylith spiral board successively, form a plurality of sprays districts, each spray is provided with isocon in distinguishing, be interval with a plurality of spray heads on every isocon, described isocon is connected with water pump by DC tube, described vertical scrubbing tower upper end is provided with the demist layer, institute washes vertical scrubbing tower lower end and is provided with discharge outlet, described discharge outlet is communicated with water tank.
As a kind of improvement of the utility model negative-pressure type wet scrubber, described vertical scrubbing tower is separated by two spiral boards, forms two sprays and distinguishes.After dusty gas enters spraying box by air inlet, distinguish through evenly rising to spray after the spiral board shunting, once spray, that passes through single treatment passes through two layers of spiral board again than clean gas, carry out again the secondary spraying washing, thoroughly after washing, by the demist layer, enter blower fan through pipeline, discharge at last.This process directly avoided in the dusty gas with have destructive material to the direct injury of blower fan, greatly extended the service life of blower fan.
As a kind of improvement of the utility model negative-pressure type wet scrubber, be respectively equipped with observation port outside described spray district and demist floor.Can observe the situation of gas scrubbing in spray district and demist floor by observation port, the convenient blower fan of controlling.
Compared with prior art, the utility model has the advantages that: the utility model adopts spiral board that vertical scrubbing tower is divided into a plurality of sprays districts, after dusty gas enters vertical scrubbing tower by air inlet, distinguish through evenly rising to spray after the spiral board shunting, once spray, that passes through single treatment passes through two layers of spiral board again than clean gas, carry out again the secondary spraying washing, thoroughly after washing, by the demist layer, enter blower fan through pipeline, discharge at last.This process directly avoided in the dusty gas with have destructive material to the direct injury of blower fan, greatly extended the service life of blower fan.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below just with reference to the accompanying drawings the utility model is further described.
As shown in Figure 1, a kind of negative-pressure type wet scrubber, comprise a vertical scrubbing tower 1 and a blower fan 2, vertical scrubbing tower 1 is connected by pipeline 3 with blower fan 2, vertical scrubbing tower 1 from top to bottom is interval with polylith spiral board 4 successively, form a plurality of sprays district 5, each spray is distinguished in 5 and is provided with isocon 6, be interval with a plurality of spray heads 7 on every isocon 6, isocon 6 is connected with water pump 9 by DC tube 8, vertical scrubbing tower 1 upper end is provided with demist layer 10, and vertical scrubbing tower 1 lower end is provided with discharge outlet 11, and discharge outlet 11 is communicated with water tank 12.
Wherein, vertical scrubbing tower 1 is separated by two spiral boards 4, forms two sprays and distinguishes 5.After dusty gas enters vertical scrubbing tower 1 by air inlet 13, distinguish 5 through evenly rising to spray after spiral board 4 shuntings, once spray, that passes through single treatment passes through two layers of spiral board 4 again than clean gas, carry out again the secondary spraying washing, thoroughly after washing, by demist layer 10, enter blower fan 2 through pipeline 3, discharge at last.This process directly avoided in the dusty gas with have destructive material to the direct injury of blower fan 2, greatly extended the service life of blower fan 2.
Spray district 5 and demist floor 10 outside are respectively equipped with observation port 14.Can observe the situation of spray district 5 and the 10 interior gas scrubbing of demist floor by observation port 14, the convenient blower fan 2 of controlling.
Operation principle of the present utility model is: after opening blower fan 2, blower fan 2 is by constantly siphoning away the air in vertical scrubbing tower 1, the interior formation negative pressure state of vertical scrubbing tower 1, force atmospheric pressure that the dusty gas of control of dust entrance is compressed into pipeline, enter vertical scrubbing tower 1 by pipeline and wash, distinguish 5 through evenly rising to spray after spiral board 4 shuntings, after twice spray district's 5 washing, clean air enters blower fan 2 by pipeline 3 again, discharges at last.Avoided blower fan to suffer the shock of the materials such as dust, stopped blower fan 2 and damaged because containing destructive material in dusty gas.
