Abstract

The utility model provides an externally-communicated vertical type three-return-stroke smoke-eliminating dust remover. The smoke-eliminating dust remover is characterized in that: an inner pipe barrel is coaxially arranged at the upper part of the dust remover, a stroke-guide spiral sheet is arranged at the upper part in the inner pipe barrel, the inner pipe barrel is coaxially butt-jointed with a barrel cover by an inner flange at the upper opening position, and a plastic hollow spherical filler is contained in an interlayer between an outer barrel body and the inner pipe barrel; a right-angle bent pipe barrel and at least one stroke-guide spiral sheet are arranged in a round barrel at the lower part, one end of the right-angle bent pipe barrel stretches out from the rim of the upper part of the barrel body and is used as a dustless gas output pipe, and the other end coaxial with the barrel body is used as a spiral core barrel; and a gas communicating pipe for communicating gas in upper and lower barrels is arranged on the corresponding axle line of the dustless gas outlet pipe. Dust-contained smoke is completely heat-exchanged and mixed with water after the processes of spraying dust removal, centrifugal cyclone dust removal, impact dust removal, washing dust removal and core filtering dust removal are carried out on the dust-contained smoke at the upper part of the dust remover; at the moment, damp and hot water-contained smoke is more beneficial for the function exerting of a cyclone gas-water separator at the lower part; therefore, the smoke-eliminating dust remover is suitable for carrying out wet-method smoke eliminating and dust removing on small/medium-sized coal-fired furnaces and kilns.

Description

The vertical three backhaul device for abatement of smoke and dust of outer connection

Affiliated technical field

The utility model relates to a kind of utensil of smoke abatement and dust control, particularly to the utensil of middle-size and small-size coal furnace, kiln wet method smoke prevention and dust control.

Background technology

The utility model is to I on March 23 2009 applying date, the patent No. 200920009280.7, utility model title: the moisture trap of " ball packing smoke washer " and its underpart, the application that proposes after technological improvement.

Summary of the invention

The purpose of this utility model to provide exactly a kind of after technological improvement efficiency of dust collection higher, the better drum type of smoke effect is outer to be communicated with vertical three backhaul device for abatement of smoke and dust.

The technical scheme that the utility model adopted is: by two isometrical can not contour drum, upper and lower butt joint is as the external form agent structure, it is characterized in that: the top concentric is provided with interior socket, interior socket internal upper part is provided with the flight of a helical pitch, interior socket relies on the inner flange at place suitable for reading to dock with the bung concentric, and polymer hollow ball-shape filler is housed in the interlayer of exterior bowl and interior socket; In the drum of bottom, be provided with the flight of quarter bend socket and at least one helical pitch, one end of right-angle elbow pipe stretches out from staving upper edge edge, as dustless gas outlet pipe, the other end and staving concentric are as the helix core tube, and the air communicating pipe that gas is communicated with in the bucket is located on the corresponding axis of dustless gas outlet pipe up and down.

The beneficial effects of the utility model are: after ash-laden gas is subjected to the process of spraying and dedusting, centrifugal force cyclone dust removal, impact dedusting, cleaning dust, filter element filtering dedusting on the top of this deduster, flue gas with water abundant heat exchange takes place to be mixed, at this moment, moisture damp and hot flue gas more helps the performance of bottom whirlwind moisture trap (I improve design according to the tubular cyclone dust collectors) function, therefore efficiency of dust collection is higher, and smoke effect is better.

Description of drawings (schematic diagram)

Below in conjunction with accompanying drawing the utility model is described in further detail.In the accompanying drawings: 1 ash-laden gas enters pipe; 2 dustless gas outlet pipes; 3, spray feed pipe (with buck or the recycling desulfurization and dedusting of doing of limewash); 4 sewage overflow pipes; 5 upper barrel bodies; 6 lower barrel bodies; 7 bungs; The bucket end on 8; At the bottom of 9 times buckets; Socket in 10 (how many mouth entry is the key of smoke abatement and dust control situation at the bottom of the interior socket, also is the factor of coupling blower fan power); Socket flights in 11 (flight can cause flue gas and water to make helical flow, can guarantee that tube wall do not tie black dirt, and the water bottom impacting rotates, and impels the filler pivoting friction, can guarantee that the gap of filler is not stopped up by black dirt); 12 helix core tubes; 13, flight; 14 air communicating pipes (can be rectangular tube, also can be round tube); 15 top overflow pipes (can be hidden in air communicating pipe); 16 polymer hollow ball-shape fillers); 17 water blockings (the draining scale removal is used when stopping using); 18 lid mouthful flanges; 19 abutted flanges; 20 supporting legs; 21 blocks (block can prevent that filler from ringing off with air-flow); 22 communicating pipe the mating interface pipe.Arrow is represented flue gas flow direction among the figure, and intermittent line is represented water.

The specific embodiment

1, rolls isometrical exterior bowl (5,6) that can be not contour, with the radius of exterior bowl (5,6) diameter, again with 1/3rd diameters of exterior bowl (5,6) diameter as dustless gas outlet pipe (2) as interior socket (10); 1.25 times of diameters with dustless gas drain (2) diameter as helix core tube (12).

2,, feed pipe (3), ash-laden gas are entered pipe (1), bung (7) composition one on top; Staving (5) the bucket end (8) and ring flange (19) are formed one; Interior socket (10) is formed one with flight (11).

3, in the bottom, after staving (6), the bucket end (9), overflow pipe (4), water blocking (17), flight (13) composition one, concentric fixedly helix core tube (12) inserts dustless gas outlet pipe (2) and fixing.

4, open on the corresponding axis of dustless gas outlet pipe (2) in the upper and lower hole that air communicating pipe (14) is corresponding.

5, with ring flange (9) upper and lower staving (5,6) is docked, behind the filler of packing into (16), the butt tube of sealing bung (7) and air communicating pipe (14).

Claims

1. vertical device for abatement of smoke and dust of tubbiness, by two isometrical can butt joints up and down by not contour drum, as the external form agent structure, it is characterized in that: the top concentric is provided with interior socket, interior socket internal upper part is provided with the flight of a helical pitch, interior socket relies on the inner flange at place suitable for reading to dock with the bung concentric, polymer hollow ball-shape filler is housed in the interlayer of exterior bowl and interior socket, in the drum of bottom, be provided with the flight of quarter bend socket and at least one helical pitch, one end of quarter bend socket stretches out from staving upper edge edge, as dustless gas outlet pipe, the other end and staving concentric are as the helix core tube, and the air communicating pipe that gas is communicated with in the bucket is located on the corresponding axis of dustless gas outlet pipe up and down.
