Description

A kind of wet type flue gas desulphurization device
The utility model relates to a kind of wet type flue gas desulphurization device, is applicable to station boiler, the gas cleaning of Industrial Boiler and Industrial Stoves.
The flue gas ash removal of the present medium and small boiler of China is used gallet water curtain dust collector more, and it mainly is made up of king-tower, secondary tower, water supply installation, import and export flue and sewage draining exit etc.To entering, particle is concentrated into the inner wall of tower near zone to this smoke eliminator flue gas from the tower undercutting, is supplied water by the tower circumference and catches and dedusting at the moisture film of inwall formation.Flue gas and water are short time of contact, effectively desulfurization, and exhaust band water is serious, jeopardizes the air-introduced machine security of operation.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of while high-effective dust-removing, desulfurization are provided, and the wet type flue gas desulphurization device of the good demist of energy.
For achieving the above object, the technical solution adopted in the utility model is, on king-tower, have gas approach and sewage draining exit, the pillar feed pipe is set in king-tower, the eddy flow plate, above the eddy flow plate, nozzle is set, nozzle and feed pipe communicate, and have exhanst gas outlet and leakage fluid dram on secondary tower, on secondary tower top the eddy flow plate are set, in the secondary tower bottom gas-water separation jacketed tower is set, splitter column and scrubbing tower are installed between king-tower and secondary tower, many tubules are set in splitter column, the feed pipe that has a plurality of apertures is set in scrubbing tower, step plate washer, leakage fluid dram and eddy flow plate.
Advantage of the present utility model is:
1. two-stage dedusting: the multistage monoblock type eddy flow plate of configuration in the king-tower, strengthen the swirling motion of air-flow, strengthen centrifugal action, form primary dust removing efficiently, flue gas is shunted by multitube, embathe through cleaning solution in scrubbing tower, further improve efficiency of dust collection, the employing of two-stage dedusting makes the efficiency of dust collection of this utility model be higher than other water dust scrubber.
2. two-step desulfurization: cleaning solution disseminates by around the middle mind-set in the king-tower, flue gas all can effectively contact in the whole space of tower with liquid film, liquid pearl and liquid mist, the carrying out that helps desulphurization reaction, the flue gas that disperses in the scrubbing tower fully contacts with cleaning solution, prolong the reaction time, finish further sweetening process, the utlity model has higher desulfuration efficiency thereby make.
3. twice demist: first order monoblock type eddy flow plate demister is arranged on scrubbing tower top, arranged second level monoblock type eddy flow plate demister at secondary tower, and gas-water separation jacketed tower is set in the secondary tower bottom, avoid the secondary of liquid mist to carry, guarantee the aridity of outlet flue gas and the safety in operation of upstream device.
4. two-stage dedusting, two-step desulfurization, twice demist are organically combined, realized the best of breed of device, brought into play the maximum efficiency of device.
5. the utility model integrated apparatus also can be placed on multitube knockout tower, scrubbing tower and secondary tower power plant electrostatic precipitator back, effectively desulfurization.
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, on king-tower I, have door 5, gas approach 1 and sewage draining exit 15, door 5 also can be opened on other tower.Pillar feed pipe 2 is set in king-tower I, and eddy flow plate 3 is provided with nozzle 4 above eddy flow plate 3, nozzle 4 can be arranged ringwise and feed pipe 2 communicates, and has exhanst gas outlet 12 and leakage fluid dram 13 on secondary tower IV, on secondary tower IV top eddy flow plate 10 is set, the bottom is provided with gas-water separation jacketed tower 11.Splitter column II and scrubbing tower III are installed between king-tower I and secondary tower IV, many tubules 6 are set in splitter column II, can make by anti-corrosion material.Feed pipe 8, step plate washer 7, leakage fluid dram 14 and the eddy flow plate 9 that has a plurality of apertures is set in scrubbing tower III.
Under the effect of eddy flow plate 3, the flue gas that the bottom tangentially enters all keeps strong rotatablely moving in whole king-tower height, and the solid particulate matter in the flue gas is concentrated into king-tower inwall near zone.The cleaning solution that pillar feed pipe 2 provides is therefrom disseminated around the mind-set by nozzle 4, forms liquid pearl, liquid mist in the space through eddy flow plate 3 bump backs, at eddy flow plate 3 surfaces and king-tower inwall formation liquid films, catches thereby grit pounced on.Flue gas is also owing to carrying out desulphurization reaction with effective contact of cleaning solution.Dust-laden (solid grit and CaSO 3, CaSO 4Particle) waste liquid is discharged from the sewage draining exit 15 of king-tower bottom.King-tower top links to each other with splitter column, and this tower and subsequent washing tower all can be made by anticorrosive material.Enter scrubbing tower through the flue gas after multitube 6 shunting, by feed pipe 8 feed fluids, form a plurality of trapezoidal rinsing district of certain liquid level in the tower, further finish dedusting and desulfurization by fluid-tight plate washer 7.Liquid level can be shown by liquid level gauge.The small amount of drop that rinsing is taken out of to the motion of scrubbing tower inwall, forms liquid film through 9 effects of eddy flow plate, flows back to scrubbing section, and the waste liquid after rinsing is discharged through leakage fluid dram 14.The clean flue gas of scrubbing tower enters secondary tower, moves downward through eddy flow plate 10 back eddy flows.Flue gas is drawn from the cover tower 11 that is positioned at the secondary tower center, avoids dry flue gas reentrainment drop, thereby makes the unlikely band liquid of flue gas after being purified and influence equipment operation.
Above-mentioned eddy flow plate 3,9 and 10 is a monoblock type eddy flow plate, can be supported by inner wall of tower.Above-mentioned eddy flow plate 3,9 and 10 be set to one-level or more than the one-level.
This device can be in-line and arrange or the layout that is square according to field condition.
Splitter column II, scrubbing tower III and secondary tower IV three can organic assembling, are placed on station boiler high-efficiency dust remover back, make the usefulness of desulfurization separately.
