Abstract

The utility model relates to a multiple pneumatic desulfurizing, dedusting and purifying tower with double barrels, which belongs to a wet desulfurizing and dedusting device. The utility model provides a multiple pneumatic desulfurizing, dedusting and purifying tower with the double barrels with high dedusting efficiency to solve the problem of low efficiency of the existing desulfurizing and dedusting device. The utility model comprises a main cylinder (1) and an auxiliary cylinder (2) vertically arranged. The main cylinder (1) and the auxiliary cylinder (2) are connected into an integral body by an ash water tank (3). The utility model is characterized in that a flue gas inlet (4), a still pressure box (5), a pre-liquid distributing pipe (6), a partition board (7) with a hole and a venturi pipe (8) are orderly arranged in the main cylinder (1) from the top to the bottom of the main cylinder; a sieve tray (10) for cross flow, a rectifying plate (11), a horizontal splashing plate (12), a post-liquid distributing pipe (13), a dewatering folded plate (14) aslant arranged and a smoke outlet (15) are arranged in the auxiliary cylinder from the bottom to the top of the auxiliary cylinder.

Description

The multiple Pneumatic desulphurization udst separation of bitubular tower

Technical field:

The utility model is to belong to wet type desulfurizing dust collector.

Background technology:

At present, the venturi tube duster that China widely applies, sieve tray desulfurizing dust-collector and impulse wet dust collector, but efficiency of dust collection is all lower.

Summary of the invention:

The utility model is exactly to solve the existing not high problem of desulfurizing dust-collector efficient, and the multiple Pneumatic desulphurization udst separation of the high bitubular of a kind of efficiency of dust collection tower is provided.

The utility model adopts following technical scheme: the utility model comprises the main tube of vertical arrangement, secondary tube, gray water tank will be led tube, secondary tube is connected in one, its structural feature is to be provided with smoke inlet, plenum chamber, preposition liquid distributor successively from the top down in the main tube, has the dividing plate in hole, Venturi tube; Be disposed with the cross-flow sieve tray from bottom to top in the secondary tube, cowling panel, level are spattered plate, rearmounted liquid distributor, tilting dehydration flap, outlet flue.

The beneficial effects of the utility model:

This purifying column desulfurization, dedusting, dewatering process flow are smooth and easy naturally, rationally and simple; Upper and lower whole process is by twice in purifying column for flue gas, and the time of staying is the twice of co-altitude purifying column, has guaranteed SO ₂Fully the finishing of absorption, absorption reaction process; Its structure fabrication is simple, and flue gas short circuit chance is few in the deduster; The floor space of external dimensions and ceramic multitube desulfurizing dust-collector, suitable highly substantially; But desulfurization, dust removing effects are splendid, reliable and stable, and total dust removal efficiency is greater than 99% (being more suitable for the high flue gas of dustiness), desulfuration efficiency＞90%; Liquid-gas ratio＜1.0L/m ³Resistance＜900Pa, resistance is little, and running cost is economized, need not be changed air-introduced machine, guarantees that boiler burns well; The deduster inner gas passage is unobstructed, and when stopping using air-introduced machine, burner hearth can malleation not occur and smolder; Tilting flap dehydrating effect is good, can not stop up, and blower fan is not had corrosion; Pore cloth liquid, recirculated water need not filter, can not stop up, and maintenance capacity is few.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

1, main tube, 2, secondary tube, 3, gray water tank, 4, smoke inlet, 5, plenum chamber, 6, preposition liquid distributor, 7, the dividing plate that has the hole, 8, Venturi tube, 9, the water surface, 10, cross-flow sieve tray, 11, cowling panel, 12, level spatters plate, 13, rearmounted liquid distributor, 14, tilting dehydration flap, 15, outlet flue, 16, the buck outlet.

The specific embodiment:

The utility model comprises the main tube 1 of vertical arrangement, secondary tube 2, and gray water tank 3 will be led tube 1, secondary tube 2 is connected in one, and is provided with smoke inlet 4, plenum chamber 5, preposition liquid distributor 6 successively from the top down in the main tube 1, has the dividing plate 7 in hole, Venturi tube 8; Be disposed with cross-flow sieve tray 10 from bottom to top in the secondary tube 2, cowling panel 11, level are spattered plate 12, rearmounted liquid distributor 13, tilting dehydration flap 14, outlet flue 15.

Hole with the dividing plate 7 in hole can be Venturi tube (being reducing pipe).

Cross-flow sieve tray 10 can be oblique setting with respect to secondary tube 2.

Below in conjunction with a description of drawings course of action of the present utility model:

Flue gas is in smoke inlet 4 enters main tube 1, after the ejection cleaning solution is atomized by flue gas in the preposition liquid distributor 6, after dividing plate through having the hole 7 produces speed speed variation (this moment, flue gas fully mixed with cleaning solution) again, through Venturi tube 8 along the water surface 9 of gray water tank 3 cross-flow sieve tray 10 until secondary tube 2, cowling panel 11, level are spattered cleaning solution, the tilting dehydration flap 14 of

plate

12,13 ejections of rearmounted liquid distributor, after further purifying, discharge through outlet flue 15; Solid particle in the flue gas falls within the gray water tank 3, discharges through buck outlet 16.
