Abstract

The utility model relates to a water-fog desulfurizing dust remover which is used for the desulfurization and the dust removal of the smoke of a coal-burning furnace, increasing the rate of desulfurization and dust removal and overcoming the defect that the smoke processed by the dust remover of the same type still has much pollutants. The water-fog desulfurizing dust remover comprises an internal cylinder connected with a boiler smoke exhausting port and provided with a downward opening, an external cylinder enclosing the internal cylinder, a water tank enclosing the external cylinder, and a blasting pipeline connected with the water tank. The improvement is as follows: the upper part in the external cylinder is provided with a spraying nozzle, and a rotary blade wheel covering the gap of the internal cylinder and the external cylinder is arranged on the combined part of the upper end of the external cylinder and a chimney. The utility model has the advantages that the spraying nozzle which is additionally arranged enlarges the mixing space of smoke and water, increases the absorbing rate of water on the pollutants and improves the coagulation of smoke and dust, and the blade wheel which is additionally arranged prevents the discharge of the water fog and reduces the amount of the pollutants dispersed into the atmosphere with the water fog.

Description

A kind of fog desulfurizing duster

Technical field

The utility model belongs to technical field of heating, is specifically related to combustion products removing, treating apparatus in the combustion apparatus.

Background technology

The existing device for eliminating smoke and dust that is used for the coal-burning boiler smoke discharging pipe mostly is fog desulfurizing duster, its structure comprise connect the boiler exhaust gas mouth, Open Side Down advances the cigarette inner core, surround the urceolus of inner core, the water tank that surrounds the urceolus bottom and be tightly connected with urceolus, the water atomization blowing line of connection water tank bottom.In the flue gas after this kind desulfurizing dust-collector is handled, still can be easier to detect sulphur and dust, illustrate that its operating efficiency awaits improving.

Summary of the invention

The purpose of this utility model provides a kind of fog desulfurizing duster, is used for the coal burning flue gas desulfurization dedusting, improves desulfurization dust-removing efficiency, overcomes flue gas that existing this type of deduster handles and still has deficiency than multi-pollutant

The utility model comprises being connected with the boiler exhaust gas mouth in the existing fog desulfurizing duster, Open Side Down advances the cigarette inner core, surrounds the urceolus of inner core, and the water tank that surrounds the urceolus bottom and be tightly connected with urceolus connects the water atomization blowing line of water tank bottom.The improvement of being done is: establish the trickle shower nozzle at the urceolus internal upper part, in the upper end of urceolus and the joining place of chimney the rotary blade that covers inside and outside tube gap is arranged.

The course of work of the present utility model is: flue gas is after inner core imports deduster, mix through the water smoke that air blast produces with outer tube bottom earlier, carry out desulfurization, dedusting, flue gas is in the ring set rising of prolonging between the inside and outside tube, water with the shower nozzle spray mixes again, further desulfurization and dedusting, and condense into larger particles, fall the deduster bottom.The impeller that water smoke is rotated is blocked in the deduster, and clean flue gas rises to chimney by deduster, is discharged into atmosphere.

Good effect of the present utility model is the blending space that the trickle shower nozzle set up strengthens the cigarette G﹠W, has improved the absorptivity of water to pollutant in the flue gas, and has improved condensing, falling of flue dust.The impeller that increases in urceolus upper end stoped the discharge of water smoke, reduced pollutant and has been diffused into the quantity of atmosphere with water smoke, increased substantially the clean level of the boiler waste gas that is discharged into atmosphere.

The specific embodiment

Consult Fig. 1, Fig. 2, employing comprises connection boiler exhaust gas mouth, the inner core 1 that Open Side Down, surround the urceolus 2 of inner core opening portion, the water tank 3 that surrounds the urceolus bottom and be tightly connected with urceolus, the blowing line 4 that connects water tank bottom, on urceolus top Shower tap 5 is installed, injection flow rate is a benchmark as if the urceolus with diameter 400mm, is 1.6 liters/minute.In the inner core on urceolus and the gap of urceolus impeller 6 is installed.Consult Fig. 3, impeller is made up of outer cylinder 6-1 and the blade 6-2 that is fixed on the radial arrangement on the outer cylinder.

Claims

1, a kind of fog desulfurizing duster, comprise with the boiler exhaust gas mouth be connected, Open Side Down advances the cigarette inner core, surround the urceolus of inner core, the water tank that surrounds the urceolus bottom and be tightly connected with urceolus, the water atomization blowing line that connects water tank bottom, the improvement of being done is: establish the trickle shower nozzle at the urceolus internal upper part, in the upper end of urceolus and the joining place of chimney the rotary blade that covers inside and outside tube gap is arranged.
