Abstract
The utility model relates to a desulfurizing and dusting device with a water film, which is used for desulfurizing and dusting smoke and is composed of a preliminary desulfurizing device, a venturi, a drop catcher, etc., wherein the preliminary desulfurizing device has a smoke inlet; a water seal tank and a funnel-shaped oblique tank are arranged at the bottom of the preliminary desulfurizing device; the front and the back ends of the venturi are respectively connected with the preliminary desulfurizing device and the drop catcher; a sprayer is arranged in a cavity; a water-smoke separation device and a one-stage and a two-stage vortex sieve plates are arranged in the drop catcher; a flowing water film is arranged on the inner wall of the utility model; the top of the utility model has a smoke outlet. The utility model has the advantages of simple structure, easy fabrication, low investment, convenient operation, high desulfurizing and dust removing efficiency, stable operation and long busy period and solves the water carrying problem of a fan.
Description
The utility model relates to a kind of flue gas desulfur device, especially a kind of water desulfurizing-dusting device.
The desulfurization and dedusting of flue gas includes multiple flue gas desulfurization techniques such as wet method, dry method and semidry method, but up to the present, still with the most use in actual applications with wet desulfurizing process, and wherein use lime, lime stone---the sulfur removal technology that the gypsum wet washing is technical comparative maturity, practicality is maximum, operation conditions is the most stable.Ripe sulfur method also need dispose advanced equipment, and the existing Wet-type desulfurize and dust removing equipment that uses, more or less also exist the aspect of some shortcomings,, haptoreaction time low as desulfurization dust-removing efficiency is short, equipment investment is many, complicated operation, equipment operation troubles are many, easily produce problems such as secondary pollution, operating cost height.
The purpose of this utility model is to provide that a kind of process equipment is simple, easy to manufacture, haptoreaction time length, reduced investment, easy to operate, efficiency of dust collection is high, do not produce secondary pollution, stable water desulfurizing-dusting device.
The purpose of this utility model is achieved in that a kind of water desulfurizing-dusting device, by the pre-devulcanizer of rectangle, formations such as two ends flare Venturi tube and cylindrical shape drop catcher, its pre-devulcanizer front side wall is provided with gas approach, follow the Venturi tube front end on the rear wall, the sidewall of rear end and drop catcher then, pre-devulcanizer, Venturi tube and drop catcher internal upper part are provided with spray equipment, pre-devulcanizer inner bottom part is provided with and is connected to the infundibulate skewed slot on water sealed tank and the inwall, Venturi tube rearward end tube wall is provided with door to access, the pre-portion of drop catcher is provided with exhanst gas outlet, on spray equipment, be provided with moisture separator, be provided with one-level eddy flow sieve plate and secondary eddy flow sieve plate below, the moisture film that has one deck evenly to flow on the inwall from top to bottom, bottom sidewall are provided with the ash door that overflows.Its operation principle is as follows: flue gas is entered in the pre-devulcanizer by the flue gas mouth, contact with the absorption liquid that spray equipment sprays into, and the cooling dedusting, the absorption liquid of band dirt falls in the water sealed tank along the infundibulate skewed slot, finishes the first grade desulfurizing dedusting; Flue gas enters Venturi tube then, its Venturi throat cigarette speed is the highest, flue gas is strong turbulent motion, the press water that sprays at trunnion porch and spray equipment is the vaporific whole throat that is covered with, the moving grit of flue gas high speed breaks through the air film around the globule and is attracted on the globule, the grey water droplet of coacervating large particle is finished the secondary desulfurization and dedusting; Subsequently flue gas by drop catcher lower tangential or snail to introducing, by one-level and secondary eddy flow sieve plate, rise at the drop catcher inside spin, contact absorption with the water that spray equipment sprays into, the buck that forms and soot particle separate by moisture film with flue gas under action of centrifugal force and adsorb, deliver to the bottom ash bucket by moisture film, discharge, finish three, the level Four desulfurization and dedusting from ash discharging hole; Clean flue gas is introduced chimney by air-introduced machine from outlet after through the moisture separator on top and is discharged, and has reached the purpose of flue gas desulfurization and dedusting.
The utility model is simple in structure, reduced investment, easy to operate, desulfurization dust-removing efficiency is high, stable, long service life, has overcome the problem of fan belt water, non-secondary pollution has practical reference value.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Shown in Fig. 1-2, a kind of water desulfurizing-dusting device, by the pre-devulcanizer of rectangle (4), two ends flare Venturi tubes (5) and cylindrical shape drop catcher formations such as (12), its pre-devulcanizer (4) front side wall is provided with gas approach (3), follow Venturi tube (5) front end on the rear wall, the sidewall of Venturi tube (5) rear end and drop catcher (12) then, pre-devulcanizer (4), Venturi tube (5) and drop catcher (12) internal upper part are provided with spray equipment (9), pre-devulcanizer inner bottom part is provided with and is connected to infundibulate skewed slot (2) on water sealed tank (1) and the inwall, Venturi tube rearward end tube wall is provided with door to access (6), the drop catcher top is provided with exhanst gas outlet (7), on spray equipment (9), be provided with moisture separator (8), be provided with one-level eddy flow sieve plate (10) and secondary eddy flow sieve plate (11) below, the moisture film (13) that has one deck evenly to flow on the drop catcher inwall from top to bottom, bottom sidewall are provided with the ash door (14) that overflows.
