Abstract

The present invention discloses a whirl-stirring wet desulphurization deduster belonging to environmental protection equipment for processing flue gas pollution, and especially whirlwind dedusting equipment having a spraying apparatus. The deduster comprises a purifier main body, a desulfurizer circulating device and an air inducing apparatus. The purifier main body, of which a top is a cylindraceous purification chamber and a bottom is a cone dust storage warehouse, is mounted on a support. An involute flue gas guide cylinder having a rectangular cross section, of which a front is equipped with a desulphurization atomizer, is mounted at the lower part of the purification chamber. A desulfurizer sprayer is disposed on the desulphurization atomizer, and a desulfurizer conveyer pipe connected to the desulfurizer sprayer connects to a reaction displacement pool. An overflow water case with an overflow pipe communicating with the reaction displacement pool is mounted on one side of the dust storage warehouse. An interface of the air inducing pipe is installed on the top of the purifier. The equipment has high dedusting and desulphurization efficiency, a compact structure and a small land occupation area, and can be used for smoke prevention and dust control in various pieces of equipment such as miniature, medium-sized boilers and industrial kilns, having an obvious effect in reducing environmental pollution of flue dust especially sulfur containing flue gas.

Description

Revolve sharp wet type desulfurizing dust collector

Technical field

The invention belongs to the environmental protection equipment that is used for the smoke treatment pollution, particularly have the cyclone dust removal equipment of spray equipment.

Background technology

Cyclone dust collector is used widely in the flue gas of equipment such as boiler is handled, and the little efficient of its volume is high, but does not have desulfurizing function, does not reach environmental requirement, and common enforcement cleaner volume is big, causes the secondary pollution of acid-bearing wastewater easily.

Summary of the invention

Do not have the deficiency of desulfurizing function, the present invention that a kind of sharp wet type desulfurizing dust collector that revolves is provided in order to overcome existing cyclone type cleaner, this revolve swash wet type desulfurizing dust collector not only can dedusting, and can remove the sulfide in the flue gas, reach discharge standard.

The technical solution adopted for the present invention to solve the technical problems is: a kind ofly revolve sharp wet type desulfurizing dust collector, it is characterized in that: be made up of purifier main body, desulfurizing agent EGR, blower unit, its top of rack-mount purifier main body is columnar clean room; The bottom is the dust storage compartment of cone-shaped; The involute flue gas guide cylinder that the cross section is a rectangle is equipped with the bottom in the clean room, and the guide cylinder front end is equipped with the desulfurization atomizer, and the desulfurizing agent shower nozzle is housed on the desulfurization atomizer; The desulfurizing agent carrier pipe that connects shower nozzle connects the pH value regulating reservoir; Dust storage compartment one side is equipped with spill box, and overflow pipe communicates with the reaction displacement pool, and the induced duct interface is equipped with at the clarifier top.

The overflow adjustable pipe is equipped with in described spill box side and centrum overflow pipe its inside that joins, and the overflow adjustable pipe links to each other with overflow pipe through bolt.

Ash-valve is equipped with in the dust storage compartment bottom of described cone-shaped, and links to each other with overflow pipe through threeway.

Described desulfurizing agent carrier pipe is provided with gate valve, and desulfurizing agent carrier pipe bottom links to each other with water pump.

The sedimentation basin of Automatic Dosing device is housed between described pH value regulating reservoir and the reaction displacement pool in addition.

Operation principle of the present invention is the dust-laden of boiler or the discharge of other kiln coal combustion, when sulfur-containing smoke gas gets into deduster, at first gets into the desulfurization atomizer that desulfurizing agent forms very thin vaporific drop of particle diameter and the flue dust in the flue gas, the SO of gaseous state in atomizer ₂Fully contact makes particle flue dust humidification, weightening finish, and the granule flue dust is that core captures, condenses formation bulky grain flue dust, the SO of gaseous state each other with the drop ₂Form sulfurous acid with water,, thereby remove the SO in the flue gas with alkaline desulfurizing agent neutralization reaction ₂, along with the passing of flue gas, bulky grain flue dust and other SO that do not purify ₂Under the effect of guider, get into the purifier apparatus inward turning and swash district, at this moment flue dust, SO ₂Under the effect of air-introduced machine, revolve sharp, gas phase, liquid phase, solid phase jointly with doctor solution and become gas-liquid and mix admittedly mutually, flue dust is captured by water, falls into hypocentrum and discharges through ash-valve; SO ₂With doctor solution neutralization reaction takes place fully, clean gas gets into chimney through air inducing and enters atmosphere after the whirlwind dehydration.Reach 98% according to monitoring efficiency of dust collection of the present invention, desulfuration efficiency reaches 80-90%, 1 grade of blackness of exhaustion≤Lin Geman.

But the equipment that the invention has the beneficial effects as follows gets final product dedusting desulfurization again; Dust-removal and desulfurizing efficient height, compact conformation, floor space are little; Can be widely used in all kinds of small-sized, medium-sized boilers and Smoke Prevention and Dust Control in Industrial Furnace and use, for alleviate flue dust particularly sulfur-containing smoke gas the pollution of environment is had obvious effects.
