Description

Rotary exciting wet desulfurizing and dust-removing equipment

The utility model belongs to the technical field of mechanical engineering combustion products or the clearance or the treatment facility of burning dregs.

The wet dust-removing and desulfurizing equipment used for various industrial boilers (kilns) has low efficiency, high resistance, large water consumption, easy abrasion and easy blockage of a circulating injection system, short service life and dust and sulfur dioxide (SO) in the flue gas₂) The emission concentration of the smoke is high and can not meet the requirements of national emission standards, SO that the atmospheric environment of large and medium cities is continuously deteriorated, the health of people is endangered, and SO in the smoke gas₂Can cause respiratory diseases of people, atmospheric pollution can form acid rain, destroy soil and harm the growth of crops, can cause certain acid corrosion to articles, can also influence the product quality of industries such as chemical industry, medicine, textile, printing and dyeing and the like, and causes great loss to national economy.

The utility model aims at developing and designing a rotary wet desulphurization and dust removal integrated device, which enables the emission of flue gas to reach the national standard, and has the advantages of high efficiency, low resistance, simple operation, long service life and no secondary pollution.

The utility model discloses by box (1), install at least one in box (1) and revolve sharp monomer (2), revolve sharp monomer (2) well cylinder upper portion smoke exhaust core pipe (5), whirl dehydrator (4) at middle part, toper bucket (6) and around the cylinder lower part water conservancy diversion piece (3), dress in box (1) lower part receipts ash bucket (7) and box (1) outside lower part make-up water tank (8), the flue gas import (16) and the smoke outlet (17) on upper portion of middle part and box (1) and receive water level gauge (9) between ash bucket (7), adorn in water inlet (10) and the moisturizing mouth (11) in receiving ash bucket (7) upper portion make-up water tank (8) outside still have overflow mouth (15) and flushing mouth (12) of lower part, arrange ash mud mouth (13), arrange moisturizing import (14) and lower part and receive ash bucket (7) on moisturizing case (8) upper portion in and put up water tank (14), A pipe (18) connected with the water replenishing port (11), and the like.

The integrated equipment for desulfurization and dust removal by rotary-excitation wet method has the advantages that the alkaline liquid is used as the medium, and the dust and SO in the flue gas generated by the industrial boiler (kiln) are efficiently collected and treated₂The harmful substances are reacted to generate harmless salt substances ( ) And discharging into a sedimentation tank, wherein the clarified water can be reused, and the residue is dug and conveyed away. Thus, the desulfurization and dust removal can be realized; the device can purify the atmospheric environment to reach the emission standard, can save the operation cost, and has huge social benefit, economic benefit and good environmental benefit.

The embodiments of the present invention are described in detail below with reference to the accompanying drawings:

FIG. 4 is a structure view of a spiral-flow plate of the spiral-flow dehydrator

As shown in the figure, when the utility model is operated, firstly, alkaline liquid is injected from the water inlet (10) to the mark position of the water level gauge (9), along with the alkaline liquid entering the ash collecting water gauge (7) and gradually filling the water level, the liquid level rises to the control water level specified by the conical water bucket (6) at the lower part of the rotary excitation monomer (2), and then the industrial boiler is discharged to contain dust and SO₂The harmful flue gas enters the box body (1) from a flue gas inlet (16), then the harmful flue gas respectively passes through a flow deflector (3) in each rotary excited monomer (2), under the action of the flow deflector, the flue gas rotates at a high speed into the alkaline liquid in the conical water bucket (6), so that the alkaline liquid in a static state in the conical water bucket (6) also rotates under the action of centrifugal force and system pressure difference, at the moment, the liquid level is parabolic, the liquid level of the side wall is lifted to have the tendency of sealing the flue gas inlet (16), the flue gas only has the only inlet, under the condition, the rotating flue gas rushes into the alkaline liquid, the gas and the liquid move relatively and rotate together to achieve dynamic balance, the gas-liquid two-phase flow is changed into gas-liquid mixed-phase flow, the excited water drops collide under the action of the centrifugal force, and a water film is formed on the inner wall of the rotary excited monomer (2). The flue gas can be fully processed under the action of various mechanisms such as rotary excitation, centrifugal water film and the likeChemical reaction and high-efficiency purification, thereby achieving the aims of desulfurization and dust removal, purified flue gas is subjected to rotary dehydration by a cyclone plate in a cyclone dehydrator (4), is converged by a flue gas exhaust core pipe (5) and is discharged from a flue gas outlet (17), and desulfurization products (CaSO) in liquid₄) Dust and dust are collected in the side wall of the equipment in a rotating mode and are discharged into a dust collecting hopper (7) from a conical hopper (6) after being concentrated, products and dust are accelerated to settle due to the fact that the rotating speed of the dust collecting hopper is slowed down, the products and the dust are discharged through a mortar discharging port (13), water in mortar enters a supplementary water tank (8) to be recycled after being treated by adding chemicals (alkaline liquid). Because the temperature of the flue gas is higher, the water is promoted to evaporate faster, and the water is automatically supplied by a supply tank (8) so as to ensure the normal operation of the desulfurization and dust removal equipment.

The flow deflectors (3) in the rotary-excited single body (2) are uniformly distributed along the periphery of the lower part of the cylinder body, and the flow deflectors are arc curves. The rotational flow plates in the rotational flow dehydrator (4) are also distributed uniformly and obliquely in a plurality of pieces, and the included angle between the rotational flow blades and the plane is 10-40 degrees.
