Abstract
The utility model discloses a reversed and interlaced spiral rising device for direct discharge flue gas, belongs to flue gas purifying equipment, and particularly relates to a flue gas discharger of wet-type desulfuration equipment. The reversed and interlaced spiral rising device for the direct discharge flue gas comprises a chimney connected to the top of a desulfuration tower. The reversed and interlaced spiral rising device is characterized in that the chimney is internally provided with two sections of rotational flow regions of spiral guide grooves formed by spiral guide plates welded on the inner wall of the chimney, the rotation directions of the spiral guide grooves of the two sections of rotational flow regions are opposite to each other, which are respectively to be a clockwise rotational flow region and an anticlockwise rotational flow region, each section of the rotational flow region is provided with three guide grooves, a rotational flow buffer region is arranged between the two sections of rotational flow regions, and the upper-section spiral guide groove outlet is a rotational flow diffusion region provided with 4-8 pieces of vertical guide plates. The desulfured smoke flow forms into the rotational flow through the guide grooves, the larger liquid drops are thrown onto a tower wall to flow off along the tower wall under the action of the centrifugal force and gravity, and the smaller liquid drops are attached onto the wall plates of the guide grooves so as to be collected into a liquid forming film to flow off along with the wall plates, so that the effect of removing the fogdrop in the smoke can be achieved.
Description
Technical field
The utility model belongs to wet type desulfurizing equipment, the reverse interleaved spiral riser of particularly in line flue gas.
Background technology
In flue gas desulphurization system equipment, GGH flue gas heat exchange device is one of capital equipment of this system, and it is an introduction of foreign technology; Its main performance is to utilize former flue gas (130 ℃～170 ℃) to heat clean flue gas (50 ℃～60 ℃); Clean flue gas after the desulfurization is heated to about 80 ℃ by 50 ℃～60 ℃, and its purpose is exactly the evaporated water that reduces in the desulfurizing tower, improves the diffusivity of exhanst gas outlet pollutant; Reduce the visibility of plume, avoid chimney " to rain ".Through operation practice for many years, confirm many shortcomings such as this equipment inleakage is big, ash is stifled, resistance is big, fault is many, the benefit of this equipment; Do not support the negative effect that it produces; Maximum problem is exactly a poor reliability, and maintenance capacity is big, directly influences the normal operation of desulphurization system.
In view of above situation; State Environmental Protection Administration holds the meeting whether national desulfurization industry cancels GGH in May, 2004; GGH equipment is adopted in meeting decision Beijing-Tianjin area, city and the suburbs, scenic spot, and GGH can be cancelled in other areas, so the desulfurization facility of design has mostly been cancelled GGH at present.Cancelled the subject matter that GGH brings: the one, the desulphurization system water consumption increases, and the 2nd, condensed water increases in the flue gas, around chimney, forms so-called " chimney rain " in the 200m, and these raindrop have bigger corrosivity to building in the factory and equipment.
The utility model content
Around chimney, form " chimney rain " easily to factory building and the mordant deficiency of equipment in order to overcome existing desulfurizer; The utility model provides a kind of in line flue gas reverse interleaved spiral riser, the generation that the reverse interleaved spiral riser of this in line flue gas can alleviate chimney rain.
The utility model solves the technical scheme that its technical problem adopted: the reverse interleaved spiral riser of a kind of in line flue gas; Comprise the chimney that is connected the desulfurizing tower top; It is characterized in that: be provided with two sections eddy flow districts that have the spiral guide slot of the spiral guide plate composition that is welded on the inner wall of stack in the chimney; The direction of rotation of the spiral guide slot in two sections eddy flow districts is opposite, is respectively clockwise eddy flow district, counterclockwise eddy flow district, and every section is provided with three road gathering sills; Be provided with the eddy flow buffering area between two sections eddy flow districts, the eddy flow diffusion region of epimere spiral guide slot outlet for 4-8 sheet vertically-guided plate is housed.
The wide 500mm of described spiral guide plate, thickness are 5mm, make the surface for the ordinary carbon steel plate and are provided with the glass flake anticorrosive coat.
Long 3000mm～the 5000mm of described eddy flow diffusion region vertically-guided plate, wide 500mm, thickness 5mm makes the surface for the ordinary carbon steel plate and is provided with the glass flake anticorrosive coat.
The beneficial effect of the utility model is that the spiral guide slot of flowing through of the flue gas after the desulfurization forms eddy flow; Suitable tower wall flows down bigger drop on the tower wall because the effect of centrifugal force and gravity is thrown to; Flue gas fully contacts with the gathering sill wallboard in the spiral uphill process simultaneously; Flow down along wallboard attached to accumulating liquid film on the gathering sill wallboard than droplet, reach the effect of removing droplet in the flue gas.Present technique uses the effect of reverse swirl-flow devices to be: after flue gas removes the part droplet through counterclockwise eddy flow district; Carry out current stabilization at buffering area; The little droplet that does not remove in the flue gas gets into dextrorotation stream district and carries out the secondary demist after the collision polymerization; And reverse eddy flow is very little to the resistance that air-flow causes, and is little to the booster fan load influence of flue gas system.
