Abstract

The utility model discloses a dust removal desulphurization purifier, flue gas entrance of which is set inside a horizontal dust remover; upper side of the horizontal dust remover is provided with a spray pipe; a peripheral of a desulfurizing dust removing purifier on one side of the horizontal dust remover is provided with a front machine, wherein the front machine is composed by a cylindrical outer housing, a inner housing, an oblique dummy plate between the outer housing and the inner housing and a water spraying board set on upper end of the outer housing and the inner housing; the water spraying board is distributed with a spray pipe evenly; the flue gas rotates around the oblique dummy plate in the middle along the outer housing and the inner housing for two circles, namely 720 DEG, then raise into a main column of the purifier of the rotational flow desulphurization dust removal purifier. the utility model improves dust removal desulphurization efficiency greatly, and discharge concentration of processed SO2 is less than or equal to 200 mg/Nm<3>, while desulphurization efficiency more than or equal to 99.6%; discharge concentration of processed soot dust is less than or equal to 40 mg/Nm3; dedusting efficiency is more than or equal to 99.8%; resistance force of a desulfurizing tower is less than or equal to 1100 Pa, a draught fan takes no water, and synchronous operation rate of the desulphurization equipment and the boiler reach up to 100%, with equipment service life more than or equal to 30 years. Effect is better than now existing various desulphurization dust removal purifier.

Description

A kind of dedusting desulfurizing purifier

The utility model relates to a kind of dedusting desulfurizing purifier.

Background technology

Existing dedusting desulfurizing purifier mainly contains water dust scrubber, impacts deduster, sprays desulfurizing dust-collector, cyclone desulfuration deduster etc.; Wet-type rotational flow desulfurizing dust-collector wherein generally includes the clarifier king-tower that is made of current stabilization post, lower floor's eddy flow plate, middle level eddy flow plate, upper strata demist plate, spiral vertebral body, dehydrator, gas approach, king-tower water supply installation, secondary tower, exhanst gas outlet, ash hole etc., its smoke inlet is to enter Venturi tube, the dust-removal and desulfurizing effect of this product is still not so good, and its actual dust removing effects has only about 70%; Shortcomings such as the SO2 concentration of emission after in fact handling is usually greater than 1200mg/Nm3, and the resistance of desulfurizing tower is higher, air-introduced machine often is with water, duration of service is limited.

The utility model content

The purpose of this utility model is the improvement to the wet-type rotational flow desulfurizing dust-collector; Provide a kind of dust-removal and desulfurizing efficient fabulous,

The technical solution of the utility model is: comprise by the current stabilization post, lower floor's eddy flow plate, middle level eddy flow plate, upper strata demist plate, the spiral vertebral body, the clarifier king-tower that dehydrator constitutes, gas approach, exhanst gas outlet, the king-tower water supply installation, secondary tower, exhanst gas outlet, the cyclone desulfuration deduster that ash hole constitutes, it is characterized in that, described smoke inlet is located at horizontal deduster the inside, above horizontal deduster, be provided with sparge pipe, before being provided with, the periphery of the desulfurization dust separation device of horizontal deduster one side controls device, control the shell of device before described by round barrel shape, inner casing, oblique dividing plate in the middle of shell and the inner casing and be located at shell and the water spray plate of inner casing upper end constitutes, on water spray plate, be evenly distributed with sparge pipe, oblique dividing plate in the middle of flue gas was scratched along shell and inner casing respectively rotates two circles and amounts to 720 degree, and rising enters the clarifier king-tower of cyclone desulfuration deduster again.

Its import department of described shell and inner casing is a tangential in design, and flue gas becomes eddy current type to enter shell and inner casing respectively.

Described dehydrator is provided with filtering cover.

The utility model flue gas is by horizontal deduster, be subjected to the sparge pipe spray of horizontal deduster top earlier, control device before entering again, utilization hydrodynamics and self kinetic energy utilize the traction of eddy current to impel flue gas to produce inertia force and centrifugal force and gravity, the control flue gas separate from top to bottom go in ring in, in conjunction with the principle of roller washing machine, flue gas rises from the square horizontal deduster inlet rear screw that begins to go in ring, then formed angle, dislocation, go in ring, rotate, seethed, similar dehydrator dries and separates.And after before controlling sparge pipe on the device water spray plate and spraying again, rise again and enter the further desulfurization and dedusting of clarifier king-tower of cyclone desulfuration deduster.It is broken that whole liquid-supplying system all utilizes the flow velocity diffusion of flue gas to open by big change, forms atomizing then and gasify, further improved in the dissolving of dust and sulfur dioxide and absorption efficiency; Thereby improved dust-removal and desulfurizing efficient greatly, the SO2 concentration of emission≤200mg/Nm3 after the processing, desulfuration efficiency 〉=99.6%; Smoke dust discharge concentration≤40mg/Nm3 after the processing: its efficiency of dust collection 〉=99.8%; Resistance≤the 1100Pa of desulfurizing tower,, air-introduced machine is not with water, desulphurization plant and boiler synchronous operation rate reach 100%, duration of service 〉=30 year.Effect than existing various types of desulfurizing dust-collectors is all good.
