Abstract
The invention is a gas control device for pulp pool of smoke desulphurizing absorption tower. It relates to a device applied to limestone-plaster humidity smoke method desulphurizing device or for upgrading the efficiency of the pool. The device uses the pulp pool as main-body, a isolating board arranged in the pool, the pulp pool is divided into two parts with high pH value and low pH value, there has spray circular pump inlet and limestone pulp inlet on the wall of pool with high pH value, the inlet of limestone pulp is above the circular pump interface; there has disturber and plaster outlets on the wall of pool with low pH value, according to the rotation direction of the absorbing tower in the pulp pool, the plaster outlet is at the downstream of the pool with low pH value.
Description
Technical field
The present invention relates to a kind of device that is used for limestone-gypsum wet flue gas desulfurizer (WFGD) or similar field raising absorbent slurry pond usefulness, belong to the technical field of environmental protection equipment.
Background technology
In recent years, collection dedusting cooling, absorption, oxidative function are that the tower WFGD of list of one finds broad application the absorbent slurry pond collection CaSO on its absorption tower
3Oxidation, gypsum crystallization, lime stone dissolving and provide function such as absorbent slurry for all over the body to the spray absorption system.But these several functions are inconsistent for the requirement of slurries pH value: in order to improve CaSO
3The efficient of oxidation, gypsum crystallization and lime stone dissolving wishes that the pH value of slurries is lower, and in order to improve absorbent slurry to SO
2Absorbability then require the pH value of slurries higher.The method of the above-mentioned contradiction of present known solution is to seek compromise between two kinds of requirements, and the result must be the requirement that has only met two aspects to a certain extent simultaneously, but two aspects have been made sacrifice again simultaneously.
Summary of the invention
Technical problem; In order to overcome the problem that existing method exists, the present invention has designed a kind of fume desulfurating absorption tower slurries pond atmosphere control device, this device can be controlled slurries atmosphere in slurries pond, absorption tower in the requirement according to flue gas desulphurization system technology, provides to satisfy the slurries atmosphere that above-mentioned two aspects require simultaneously.
Technical scheme: the technical solution adopted for the present invention to solve the technical problems is: this device is with absorption tower slurries tank main body, inside in slurries pond, absorption tower is provided with division board, slurries pond, absorption tower is divided into high pH value pond and low pH value pond two parts, on the wall in high pH value pond, be provided with circulating pump interface and lime slurry import, according to the direction of rotation of the inner slurries in slurries pond, absorption tower, the lime slurry import is positioned at the upstream of spray pump inlet; Be provided with agitator and gypsum slurries outlet on the wall in low pH value pond, according to the direction of rotation of the inner slurries in slurries pond, absorption tower, the gypsum slurries outlet is positioned at the downstream in low pH value pond.Make that on the slurries direction of rotation of inside, slurries pond, absorption tower lime slurry import, spray pump inlet, gypsum slurries outlet are arranged in proper order.
On division board, have intercommunicating pore, make the rotation slurries in the slurries pond, absorption tower can pass through division board, to be communicated with high pH value pond and low pH value pond two parts.
Beneficial effect: the present invention is on the slurries direction of rotation that is caused by agitator, reasonably arrange the position of lime slurry import, spray pump inlet, gypsum slurries outlet, arrange that at lime slurry import, spray pump inlet place division board distributes, guides the diffusion and the mixing of fresh lime slurry simultaneously, make to form the special area that atmosphere is different, to satisfy the requirement of absorbent to pH value in this part.Slurries space outside should the zone then still keeps the lower atmosphere of pH value, to satisfy CaSO
3The needs of oxidation, gypsum crystallization, lime stone dissolving.
The difference in functionality that this device can be respectively the slurries pond provides suitable atmosphere, and there is higher production capacity in general slurries pond, cuts down the consumption of energy.Can be CaSO
3Oxidation, gypsum crystallization and lime stone dissolving provide pH value lower slurry environments, can provide pH value higher absorbent slurry again simultaneously.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a general structure schematic diagram of the present invention.
Have among Fig. 1: lime slurry import 1, spray pump inlet 2, division board 3, agitator 4, gypsum slurries outlet 5, slurries pond, absorption tower 6, high pH value pond 61, low pH value pond 62.
The specific embodiment
Fig. 1 is the crosscut section on absorption tower 6.The layout of lime slurry import 1, spray pump inlet 2 and gypsum slurries outlet 5 as shown in the figure.In lime slurry import 1 and spray pump inlet 2 places division board 3 is housed, its material is FRP, has some intercommunicating pores above.Totally 4 in agitator 4 can make slurries turn clockwise during work.Fume desulfurating absorption tower slurries of the present invention pond atmosphere control device is with slurries pond, absorption tower 6 main bodys, inside in slurries pond, absorption tower 6 is provided with division board 3, slurries pond, absorption tower 6 is divided into high pH value pond 61 and low pH value pond 62 two parts, on the wall in high pH value pond 61, be provided with spray pump inlet 2 and lime slurry import 1, according to the direction of rotation of slurries pond, absorption tower 6 inner slurries, lime slurry import 1 is positioned at the upstream of spray pump inlet 2; Be provided with agitator 4 and gypsum slurries outlet 5 on the wall in low pH value pond 62, according to the direction of rotation of slurries pond, absorption tower 6 inner slurries, gypsum slurries outlet 5 is positioned at the downstream in low pH value pond 62.
On division board 3, have intercommunicating pore, make the rotation slurries in the slurries pond, absorption tower 6 can pass through division board 3, to be communicated with high pH value pond 61 and low pH value pond 62 two parts.
Lime slurry import 1 is arranged in the upstream of spray spray pump inlet 2, after fresh lime slurry enters slurries pond, absorption tower 6, under the retardance and guiding of division board 3, the overwhelming majority at first enters behind the spray circulating pump adherence pressure by the spray system atomizing spray by the spray pump inlet, and droplet is absorbing SO
2After get back to slurries pond, absorption tower, proceed lime stone dissolving, CaSO again
3Process such as oxidation and gypsum crystallization.Gypsum slurries is finally discharged by gypsum slurries outlet 5.
Because the existence of division board 3 makes the slurries pond be divided into two partly: in lime slurry import 1 and the continuous adding of spray pump inlet 2 places owing to lime slurry, pH value is higher, has improved absorbent slurry to SO
2Absorbability; And other most of slurries still keep lower pH value, help lime stone dissolving, CaSO
3Oxidation and gypsum crystallization.
