The problem that will solve is, provides a multistage spiral -flow type water -bath deduster, firstly sets up spiral flow deflector at the water -bath deduster inner tube, secondly sets up annular spraying pipe respectively with the inner tube between water -bath deduster's urceolus and inner tube to at the decurrent shower nozzle of a plurality of nozzles of shower circular, improve water -bath deduster's dust collection efficiency, and improve the throughput to fine particle. The problem of should is solved the scheme set up in the spiral flow deflector of inner tube unanimously with the dust absorption air current direction of rotation of dust absorption fan, spiral flow deflector's helical pitch is 200mm, totally four sections. 8 decurrent shower nozzles of nozzle are installed at the circumference equipartition to the shower that sets up between urceolus and inner tube, set up and install 6 decurrent shower nozzles of nozzle in the annular spraying pipe of inner tube at the circumference equipartition to at horizontal shower nozzle of water -bath deduster entrance installation.

Description

A kind of Multi-stage spiral formula wet dust collector

Technical field

This utility model relates to a kind of Multi-stage spiral formula wet dust collector, it is adaptable to the pollution that improvement flue gas and dust cause and the recovery to dust.

Background technology

Cleaner unit is the requisite equipment of the pollution control such as flue gas, dust, and including the known spiral-flow water-bath cleaner unit being medium with water, its operation principle is, wet dust collector is by outer inner barrel, shower, swirl vane, moisture trap, water distribution mechanism, from overflow tank, the part composition such as automatically control, after automatic control cabinet provides enabled instruction, flue gas or the gas containing dust suck the outer tube inner chamber of cleaner unit by tangential direction under the suction of dust absorption fan, under the nebulization of centrifugal force and shower, dust granules and water are thrown toward barrel and form moisture film on cleaner unit outer tube inner wall, discharge pipe is flowed into in overflow tank under gravity along barrel, then, still inner core is entered by tangential direction by the dust-contained airflow of primary purification, again it is thrown toward inner tube wall and forms moisture film, water tank is entered from discharge pipe by gravity, water smoke entrained in air-flow falls into from overflow tank through separation and the stop of swirl vane and water retaining cover, clean air drains into air through dust absorption fan outlet, all dust of being captured enter and drain into specific bit through pipeline after overflow tank and put and be focused on. this kind of known wet dust collector there is a problem that, after dust-contained airflow enters inner core, centrifugal force is decayed, though through spray, but reduce the ability catching dust, making a considerable amount of fine dust be discharged along with dust absorption fan, efficiency of dust collection significantly reduces, and has been not suitable with current discharge standard.

Summary of the invention

This utility model provides a kind of Multi-stage spiral formula wet dust collector. One is arrange spiral flow deflector at wet dust collector inner core, and two is between the urceolus and inner core of wet dust collector and inner core is respectively provided with circular spray tube, and at the downward shower nozzle of the multiple nozzle of shower circumference.

The scheme that this utility model adopts is: the spiral flow deflector being arranged at inner core is consistent with the dust-absorbing airflow direction of rotation of dust absorption fan, and the helical pitch of spiral flow deflector is 200mm, totally four joints. The shower being arranged between urceolus and inner core installs, at circumference uniform distribution, the shower nozzle that 8 nozzles are downward, and the circular spray tube being arranged at inner core installs, at circumference uniform distribution, the shower nozzle that 6 nozzles are downward, and installs a horizontal shower nozzle in wet dust collector porch.

Effect of the present utility model is, when flue gas or dust-contained airflow enter wet dust collector, the water smoke of the transverse jet capitiform one-tenth being first arranged at wet dust collector entrance catches and enters wet dust collector urceolus with air-flow, the dust of dusty gas is caught again and gets rid of outside barrel with the centrifugal force of air-flow generation and forms moisture film by the water smoke that the shower nozzle of the circular spray tube circumference being arranged between urceolus and inner core is formed, remaining dust is pressed tangent line side with air-flow and is entered inner core, it is subject to guiding of spiral flow deflector to continue to rotate with bigger centrifugal force, the water smoke that dust is formed by the circular spray tube shower nozzle of inner core again catches, get rid of inside barrel with air-flow and form moisture film, inner/outer tube moisture film enters from overflow tank by gravity, and the water smoke entrained by air-flow separates with water retaining cover through swirl vane and stops that inflow is from overflow tank, clean air drains into air through dust absorption fan outlet. thus improve the efficiency of dust collection of wet dust collector, improve the disposal ability to fine dust simultaneously.

Detailed description of the invention

In FIG, after wet dust collector is started by electrical control cubicles follow procedure, dust absorption fan and water distribution mechanism 12 and simultaneously enter duty from overflow tank 13. wet dust collector outlet 5 is connected with dust absorption fan, under the swabbing action of dust absorption fan, flue gas or dusty gas enter wet dust collector from wet dust collector entrance 1 with tangential direction, dust granules in dusty gas is caught by the water smoke first sprayed by the inlet nozzle 17 in Fig. 2, dusty gas enters the cavity between wet dust collector urceolus 6 and inner core 8 afterwards, dust granules in dusty gas is caught by the water smoke of eight shower nozzle 2 ejections of urceolus circular spray tube, and get rid of to urceolus 6 inwall formation moisture film under the influence of centrifugal force, flow through outer discharge pipe 14 by gravity and enter from overflow tank 13, then dusty gas still enters the cavity between inner core 8 and inner prop 10 with tangential direction through inner core air flow inlet 11, the rotary orientation of the spiral flow deflector 9 being arranged in this cavity is consistent with flow rotation direction, after dusty gas enters under the guiding of spiral flow deflector 9, centrifugal force is strengthened and is rotated with bigger centrifugal force, the water smoke that remaining dust granules is sprayed by six shower nozzles 7 of circular spray tube of inner core again thoroughly catches, the barrel being thrown toward inner core 8 forms moisture film, flow through interior discharge pipe 15 by gravity and enter from overflow tank 13, all of dust granules enters and forms mud after overflow tank 13, by blow-off pipe follow procedure dispatch to specifying position to focus on or reclaim.The air-flow helically state after dust that removes rises to air-purifying chamber 3 from inner core 8, water smoke entrained in air-flow is separated when the swirl vane 16 in Fig. 2, flow into from overflow tank 12 after stop then through water retaining cover 4, and clean air exports 5 through wet dust collector and discharged by dust absorption fan. The start and stop of wet dust collector and operation are all by the programme-control set in advance.

In fig. 2,16 is swirl vane, and 17 is inlet nozzle.

In figure 3, spiral flow deflector 9 direction of rotation is consistent with flow rotation direction, helical pitch 200mm, totally four joints, and inner prop 10 is hollow body, diameter 300mm, is used for installing spiral stream guidance blade 9.

In the diagram, inner core air flow inlet 11 is two, is arranged symmetrically with, and air-flow can be made tangentially to enter inner core.
