Abstract
The utility model provides a combined type efficient smoke eliminating and desulphurizing device which is composed of a gas mist mixing section (1) which is provided with a swirl spraying device (4), a gas and liquid collision section (2) which is composed of an umbrella-shaped baffle plate (5) and an impeller (6), a gas and liquid separating section (3) and a liquid flow regeneration system, wherein, the angle of the nozzle of the swirl spraying device (4) is determined according to the number of spraying heads, the impeller has a plurality of sets of blades, and the angles of the blades are determined according to smoke gas contained sulfur content. The combined type smoke eliminating and desulphurizing device for boilers of the utility model has the advantages that the occupation space is little, the dust eliminating effect is good, the desulphurizing efficiency can reach about 90%, no secondary pollution is generated, and no water is consumed. The utility model is suitable for various boilers.
Description
The utility model belongs to industry and civil boiler apparatus field, particularly the smoke elimination desulphurization plant of boiler smoke.
Present employed boiler smoke smoke elimination desulphurization plant can be divided into wet type and dry type two classes.The wet dust desulfurization equipment effect is better than dry type equipment, but investment is big, the operating cost height, and occupation area of equipment is big, water consumption is big, corrosion is big, also has secondary pollution problems, and desulfuration efficiency is not very good yet.The dry collector volume is little, and is easy to operate, non-secondary pollution and corrosion, but dedusting is not thorough, can not solve desulphurization problem.
The purpose of this utility model provides a kind of compound efficient smoke elimination desulphurization plant of being made up of aerosol mixer, gas-liquid collision section and gas-liquid segregation section etc., reaches not only to eliminate smoke but also the purpose of desulfurization.
According to the utility model, in the air-introduced machine upstream of boiler flue, establish aerosol mixer, gas-liquid collision section and gas-liquid segregation section successively, and pipeline and liquid stream regenerative system are formed.Aerosol mixer porch is established one and is revolved the snail spray thrower, establishes gas-liquid collision section at the downside of aerosol mixer, is made up of umbrella-shaped baffle and impeller, and impeller is arranged by some groups of blades and formed.Being connected on the following gas-liquid separation section of gas-liquid collision section is made up of two groups of cylinders and the umbrella-shaped baffle that is contained on this cylinder periphery, the lower end of gas-liquid separation section joins by an elbow-shaped section and air-introduced machine, and regenerated reactor is again by a pump pipeline with revolve the snail spray thrower and join.
According to composite boiler smoke elimination desulphurization plant of the present utility model, the nozzle angle that revolves the snail spray thrower that is adopted is decided on shower nozzle quantity, and nozzle quantity depends on the size of boiler.For example for 1～10 ton of boiler, shower nozzle quantity is 3～5, and nozzle angle is 100～140 degree.
According to combined type smoke elimination desulphurization plant of the present utility model, how many blade angles of respectively organizing of impeller can selecting between 30～60 degree according to coal-fired sulfur content.Blade angle is big, collides effectively, but the resistance of air-flow is increased; Otherwise blade angle is little, and to the resistance minimizing of air-flow, the collision effect also reduces.
Load onto according to behind the combined type smoke elimination desulphurization plant of the present utility model, flue gas at first enters the aerosol mixer, and through the spray film that overwinding snail spray thrower is ejected by multi-angle, liquid mist and flue gas form and revolve vortex flow and fully mixed and contact the SO in the part of smoke
2Molecule is absorbed by the liquid mist, and remainder enters gas-liquid collision section with smog, and the surface of gas-liquid collision section is because the temperature difference forms liquid film.Flue gas at first with umbellate form baffle plate collision, carry out gas liquid reaction with baffle surface, again through impeller, the liquid film with impeller surface fully collides again, secondary response again, collision, cooling have all promoted liquid to remaining SO in the flue gas
2Absorption.Blade on the impeller to each other at an angle, flue gas forms the stronger snail motion of revolving by the back, enters the gas-liquid separation section.Under action of centrifugal force, absorbed SO
2Drop and the weight that absorbed water strengthened smokeshade and entered liquid phase region, the liquid after fluid flow tube is got back to regenerated reactor regeneration recycles.Clean gas after gas-liquid separation repeatedly enters flue through air-introduced machine and enters in the atmosphere.
Be installed in the flue position of dry collector according to composite boiler smoke elimination desulphurization plant of the present utility model, do not take additional space; Doctor solution recycles, and does not produce secondary pollution; Except that the low amounts of water evaporation, no water consumption; Desulfuration efficiency can reach about 90%; Remove the smokeshade in the flue gas more up hill and dale.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
As shown in Figure 1, the composite boiler smoke elimination desulphurization plant of the present utility model aerosol mixer (1) that connects successively, gas-liquid collision section (2), gas-liquid separation section (3) and the liquid that are installed in air-introduced machine (7) upstream of flue (8) flows regenerative system and forms:
1) aerosol mixer porch is established and is revolved snail spray thrower (4);
2) gas-liquid collision section is made up of umbrella-shaped baffle (5) and impeller (6), and impeller is rearranged by 2～4 groups of blades;
3) gas-liquid separation section is made up of two groups of cylinders and the umbrella-shaped baffle that is contained on this cylinder periphery;
The lower end of 4) gas-liquid separation section (3) joins by an elbow-shaped section (9) and air-introduced machine (7);
5) with pipeline (11) gas-liquid separation section (3) and regenerated reactor (10) are joined;
6) regenerated reactor (10) is by a pump pipeline with revolve snail spray thrower (4) and join.
Revolve snail spray thrower (4) and formed by a plurality of shower nozzle, shower nozzle quantity difference, the inclination angle of nozzle also has nothing in common with each other, the nozzle angle that promptly revolves snail spray thrower (4) is decided on shower nozzle quantity, for 1～10 ton of boiler, shower nozzle quantity is 3～5, and spray angle is 100～140 degree.
The blade angle of impeller is big more, and the collision effect is just good more, but gas-flow resistance increases.Otherwise blade angle is more little, the collision deleterious, but gas-flow resistance reduces.How many angles of blade can selecting between 30～60 degree according to coal-fired sulfur content.
According to composite boiler smoke elimination desulphurization plant of the present utility model, the desulfuration efficiency height, good dedusting effect is applicable to the smoke elimination desulfurization of the boiler of various capacity.
