Abstract

The utility model relates to a wet spiral boiler smoke-removing devulcanizer which comprises an air inducing pipe (1), a smoke gas branch pipe (13) and a purifying cavity barrel (2). A water tank (7) which contains alkaline doctor solution (8) is arranged below the purifying cavity barrel. A bottom opening of the purifying cavity barrel is below the liquid level of the doctor solution. The bottom opening of the smoke gas branch pipe is provided with a smoke gathering cavity. The lateral wall of the smoke gathering cavity is provided with a downward inclined smoke spouting pipe (11). A flue which can enable smoke gas to rotate in a spiral form is arranged in the purifying cavity barrel. A flow deflecting plate (6) is arranged at the lower part of the flue. The utility model has the advantages of small area of occupied land and lower manufacturing cost. The rate of desulfurization is over 70%.

Description

The spiral boiler smoke abatement devulcanizer of wet method

The utility model relates to a kind of purifier of boiler smoke, the spiral boiler smoke abatement devulcanizer of particularly a kind of wet method.

At present, improvement boiler emission cigarette, sulphur are a China and a global important environmental protection problem to the pollution of environment, domestic and international existing device for eliminating smoke and dust mainly contains dry method and wet method two classes, dry-method dust-removal device as: cyclone dust collectors, electrostatic precipitator etc. have certain effect to removing flue dust, but molecule is difficult to remove, and the removal of pernicious gases such as sulfur in smoke is difficulty more; Wet dedusting has impingement washing scrubber, two sharp side exciting type boiler fume purifier, water to wash one's hair formula flue gas cleaner etc., and the effect of smoke elimination desulfurization is all arranged, but complicated on its structure, floor space is many, the cost height, and inconvenience is applied.

The purpose of this utility model provide a kind of simple in structure, floor space is little, cost is relatively low, the spiral boiler smoke abatement devulcanizer of wet method of being more convenient for applying.

The utility model is realized by following scheme:

The spiral boiler smoke abatement devulcanizer of a kind of wet method, comprise induced duct, bifurcated smoke pipe and purification chamber tube, purify under the tube of chamber the water tank that fills alkaline doctor solution is arranged, the end mouth that purifies the chamber tube has smoke converging cavity under the end mouth of bifurcated smoke pipe under water tank alkalescence desulfurization liquid level, the smoke converging cavity sidewall has the smoke nozzle under being tilted to, purify to have in the tube of chamber and can make the spiral rotating flue of flue gas, the baffling dividing plate is arranged under it, and horizontal water fender and upright water fender are arranged at its top, and slag extractor is arranged in the water tank;

The above-mentioned spiral rotating flue of flue gas that can make comprises suspension rod, several meniscus and several the vertical partition plates that cooperate with meniscus horizontal by certain angle;

Slag extractor in the above-mentioned water tank is a scraping plate type eliminator.

Operation principle of the present utility model is: form certain negative pressure by air-introduced machine in purifying the chamber tube, contact with alkaline doctor solution gas, liquid in the water tank by the smoke nozzle on the smoke converging cavity from the flue gas of bifurcated smoke pipe, pernicious gases such as sulfur dioxide dissolve each other with it liquefy or aerosol, purify the purpose that reaches dedusting, desulfurization by several steps that purify in the tube of chamber, clean gas is discharged from induced duct.

When the utility model was used for 4 tons of steam boilers, the purifying rate of its flue dust was greater than 90%, desulfurization degree＞70%, and its floor space has only 4m ², height 3.8m, cost only accounts for about 10% of boiler cost.

Fig. 1 is the utility model schematic diagram;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is the B-B view of Fig. 1;

Fig. 4 is that the C of Fig. 1 is to view.

Below in conjunction with accompanying drawing structure of the present utility model is described in more detail.

As shown in Figure 1, the utility model comprises induced duct 1, induced duct connects boiler induced-draft fan, after drawing, boiler smoke is divided into the two-way pipe from stove, be called bifurcated smoke pipe 13, bifurcated smoke pipe inserts smoke converging cavity 16 downwards, smoke converging cavity is positioned on the water tank 7, smoke nozzle 11 under being tilted to is arranged on its sidewall, alkaline doctor solution 8 is housed in the water tank, be to purify chamber tube 2 on the water tank, purifying the chamber tube vertically sets up, its end mouth submerges in the doctor solution, purify to have in the tube of chamber and can make the spiral rotating flue of flue gas, four meniscus 4 and corresponding vertical partition plate 12 are arranged in this flue, make the flue gas spiral escalation, meniscus and vertical partition plate are suspended in by a suspension rod 5 and purify in the tube of chamber, and baffling dividing plate 6 is arranged at the bottom that purifies the chamber tube, and its structure as shown in Figure 4, horizontal water fender 3 is arranged at its top, its structure such as Fig. 2, shown in Figure 3, shut by baffle plate 15 with conplane another semicircle of horizontal water fender, also have upright water fender 14 on the horizontal water fender, its structure and horizontal water fender are approximate, also have scraping plate type eliminator 10 in the water tank, be used to remove the dust and the sulfide precipitation of sedimentation, water tank bottom has a tilt prop 9.
