Abstract

The utility model relates to a device for simultaneous dust removal and desulfurization. A water sprayer is arranged in the smoke flue of a smoke exhaust valve, smoke in the smoke flue automatically dissolves in the mixture of water and physic liquor flowing at high speed and fully mixes and reacts at the mixing section and the diffused section of the water sprayer under negative pressure generated by the high-speed jetting flow of the water sprayer via a water pump, and then the mixture with the smoke is sprayed out from a pipe. Water and the smoke can be separated via an impact water and smoke separator, and dust and SO < 2 > in the smoke can be absorbed by water flow to obtain the aims of dust removal and desulfuration.

Description

Smoke-melting type dust-removing desulfurizing device

The utility model relates to a kind of flue-gas dust-removing and desulfurization device, especially a kind of dust-removing desulfurating apparatus that is directly installed in the flue.

Present flue-gas dust-removing and desulfurization device, be divided into wet type and half wet type, two big classes, the dust-remover device comprises two kinds of fountain and bubble types, fountain is that flue gas is introduced spray equipment, shower nozzle on the water distributor is towards flue gas injection, water contacts with flue gas, washs the flue dust in the flue gas on the one hand, partially absorbs SO in the flue gas on the other hand ₂, but that this mode flue gas and water contact effect is bad, so efficiency of dust collection and desulfuration efficiency are all lower; Bubble type with Japanese thousand generation field Co., Ltd. product be representative, it is that flue gas is fed the container that filler and water medicine mixture are housed, after flue gas passes through, flue dust and SO ₂Be trapped, thereby realize the purpose of dust-removal and desulfurizing, this mode effect is better, but equipment complexity, easily fouling, the operational administrative inconvenience; It is carrier that half wet type refers to the lime stone, is wetting agent with water, absorbs the SO in the flue gas ₂, be equipped with cyclone dust collectors before, because water has been humidification, thereby consumption is seldom, and under the flue-gas temperature effect, water base is evaporated, and does not therefore have the problem of follow-up water treatment, and effect is also fairly good, but equipment is numerous and jumbled, and the operation operation is complicated, the cost height.

The purpose of this utility model provides a kind of dust-removing desulfurating apparatus that is directly installed in the flue, and it is simple, convenient, practical, water is few, non-scaling, investment and expense are low and effective.

The purpose of this utility model is achieved in that water sprayer is installed in flue, one end of water sprayer links to each other by the outer water pump of pipeline and flue, flue dust in the flue enters water sprayer by the negative pressure inlet mouth of water sprayer to be mixed, reacts with water, together eject then, strike on the impact type steam separator.Require the alkaline desulfurizing agent prepare according to desulfurization, by chemicals feeder injection water pump pressure pipe and after water mixes, together through water pump lifting, and after the magnetization of the pulse magnetic field generator on water pump and the water pump tube connector, enter water sprayer, in the water sprayer nozzle, produce high-speed jet, in water sprayer, form negative pressuren zone thus, flue gas in flue stream is sucked water sprayer, mix with water jet in the water sprayer mixer, absorb, react at the diffuser of water sprayer, diffuser is long, absorb, react and all compare fully flue dust in the flue gas and SO ₂Be absorbed, gas-vapor mix penetrates from water sprayer then, is ejected on the impact type steam separator, carries out steam and separates, and flue gas is purified, flue dust and SO ₂Be sent to water treatment facilities with current, because the magnetization of the pulsating field that pulse magnetic field generator produces, the problem of fouling can not appear in whole smoke processing system.

Owing to adopted such scheme, realized simple, convenient, practical, water is few, non-scaling, investment and expense is low, purpose efficiently.

Below in conjunction with accompanying drawing the utility model is further specified.

Utilize Fig. 1 to briefly explain principle of the present utility model and process below.

Water pump (15) will be through the water after water treatment facilities (13) is handled, suck by water pump suction pipe (14), pressurization promotes, chemicals feeder (16) is injected into alkaline desulfurizing agent in the tube connector (3), pulse magnetic field generator (7) magnetizes current, then be sent to water sprayer (4), flue gas is sucked by the negative pressuren zone (5) of water sprayer, mix with water jet at water sprayer mixer (6), then can be again through further magnetization of one-level pulse magnetic field generator (7), enter water sprayer diffuser (8) subsequently, at this, the SO in the flue gas ₂Alkaline desulfurizing agent generation chemical reaction with in the current is absorbed, and flue dust is distributed in the current, after impact type steam separator (9) carries out the steam separation, and flue dust and SO ₂Be back in the slag pond (12) through receiving bucket (11) with current, slag has certain alkalescence, and a part of H can neutralize ₂SO ₃And other acid, reduce the consumption of alkaline desulfurizing agent, after handling, water treatment facilities (13) recycles again through the water after the processing of slag pond, flue gas after being purified flows away from flue, enter atmosphere, also can flow to next stage water sprayer (10), multistage water sprayer effect can reach very high dust-removal and desulfurizing efficient.

According to actual condition, the utility model can adopt multistage water sprayer (10) serial or parallel connection, to improve the dust-removal and desulfurizing effect; In use also can take traverse as required, place vertically or tiltedly put etc., to adapt to different requirements; The use of multistage ejector is simultaneously finished different functions for each ejector or every group of ejector and is created conditions.

The utility model can be applied in the gas purification occasion beyond the dust-removal and desulfurizing, derives multiple product, as the removing carbon dioxide device, remove nitrogen oxide device etc.; The occasion that can also be used to purify waste water simultaneously, therefore, the utility model is a green technology that adaptive surface is very wide.
