Abstract

This invention relates to a boiler flue gas dust collector using an alkaline spraying method. It comprises an outlet pipe (1), an inlet pipe (2), a first nozzle (3), a second nozzle (4), a housing (5), a third nozzle (6), a filter screen (7), a baffle plate (8), a drain pipe (9), and an air vent (10). The outlet pipe (1) and inlet pipe (2) are located on the left side of the housing (5), and the drain pipe (9) is located at the bottom of the housing (5). A baffle plate (8) is located inside the housing (5), and a filter screen (7) is located on the right side of the baffle plate (8). The first nozzle (3), second nozzle (4), and third nozzle (6) are located at the inlet of the inlet pipe (2), above the left side of the drain pipe (9), and above the filter screen (7), respectively. The air vent (10) is located at the outlet of the outlet pipe (1). It has a simple structure, is easy to manufacture, and can effectively remove dust and desulfurize, purifying the flue gas and reducing atmospheric pollution.

Description

Spray alkali lye formula dust remover capable of eliminating smoke and desulphation

Technical field:

The utility model relates to a kind of boiler exhaust gas deduster, especially relates to a kind of injection alkali lye formula dust remover capable of eliminating smoke and desulphation that can reduce deleterious acidic gases such as sulfur dioxide in flue gas and flue dust.

Background technology:

The fume extractor of present coal-burning boiler, mostly directly enter the high-altitude by increasing chimney height, or establish an air-introduced machine and centrifugal dust collector at the outlet of chimney place, the flue gas that comes out from chimney enters centrifugal dust collector through air-introduced machine, the bulky grain flue dust in centrifugal dust collector because the effect of self gravitation sinks down into the deduster bottom discharges from the dust mouth, but still have a large amount of granule flue dust to be discharged in the air contaminated environment with pernicious gases such as flue gas and sulfur in smoke.

The utility model content:

The purpose of this utility model provides sprays alkali lye formula dust remover capable of eliminating smoke and desulphation, and it can remove the flue dust in the flue gas, particularly fine flue dust, and reduce deleterious acidic gas content such as sulfur dioxide.

In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is by pipe, smoke-intake pipe, first nozzle, second nozzle, housing, the 3rd nozzle, filter screen, water fender, blow-off pipe and bleed mouth are formed, the left side of housing is provided with pipe and smoke-intake pipe, the bottom of housing is provided with blow-off pipe, be provided with water fender in the housing, the right side of water fender is provided with filter screen, the smoke-intake pipe porch, the left side, top and the filter screen top of blow-off pipe are respectively arranged with first nozzle, second nozzle and the 3rd nozzle, the bleed mouth is arranged on the pipe exit.

Described filter screen is a del, and two summits on triangle base link to each other with the madial wall of water fender and housing respectively.

Operation principle of the present utility model is: when flue dust together enters in the housing flue dust humidification and impinging upon on the water fender gradually with the alkali lye of mouth of pipe place nozzle ejection, part flue dust is hunted down and injected liquid sweeps away, do not have captive fine particle flue dust in company with the alkali lye of the nozzle ejection of lower end, smoke-intake pipe porch together the flue through the water fender below enter the opposite side of water fender, the further humidification of some flue dust again, the up chance filter screen of tiny flue dust stops, and the alkali lye that is arranged on the nozzle ejection of filter screen top sweeps away, through injection repeatedly, collision, humidification, purify, particle flue dust wherein is washed elimination, and deleterious acidic gases such as sulfur dioxide are neutralized by alkaline jetting fluid; In order to increase the filter area of filter screen, improve filter dirt effect, said filter screen is a del; In order to simplify working process, the place does not re-use air-introduced machine at the smoke mouth of pipe, and the smoke mouth of pipe is established a bleed mouth.

The utility model simple structure is easy to make, and effectively dedusting, desulfurization are purified flue gas, reduce the pollution to atmosphere.

Description of drawings:

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

The specific embodiment:

With reference to Fig. 1, this specific embodiment is by the following technical solutions: it is by pipe 1, smoke-intake pipe 2, first nozzle 3, second nozzle 4, housing 5, the 3rd nozzle 6, filter screen 7, water fender 8, blow-off pipe 9 and bleed mouth 10 are formed, the left side of housing 5 is provided with pipe 1 and smoke-intake pipe 2, the bottom of housing 5 is provided with blow-off pipe 9, be provided with water fender 8 in the housing 5, the right side of water fender 8 is provided with filter screen 7, smoke-intake pipe 2 porch, the left side, top and filter screen 7 tops of blow-off pipe 9 are respectively arranged with first nozzle 3, second nozzle 4 and the 3rd nozzle 6, bleed mouth 10 is arranged on pipe 1 exit.

Described filter screen 7 is a del, and two summits on triangle base link to each other with the madial wall of water fender 8 with housing 5 respectively.

The operation principle of this specific embodiment is: when flue dust together enters in the housing 5 flue dust humidification and impinging upon on the water fender 8 gradually with the alkali lye of mouth of pipe place nozzle ejection, part flue dust is hunted down and injected liquid sweeps away, do not have captive fine particle flue dust in company with the alkali lye of the nozzle ejection of lower end, smoke-intake pipe 2 porch together the flue through water fender 8 belows enter the opposite side of water fender 8, the further humidification of some flue dust again, the up chance filter screen 7 of tiny flue dust stops, and the alkali lye that is arranged on the nozzle ejection of filter screen 7 tops sweeps away, through injection repeatedly, collision, humidification, purify, particle flue dust wherein is washed elimination, and deleterious acidic gases such as sulfur dioxide are neutralized by alkaline jetting fluid; In order to increase the filter area of filter screen 7, improve filter dirt effect, said filter screen is a del; In order to simplify working process, the place does not re-use air-introduced machine at the smoke mouth of pipe, and the smoke mouth of pipe is established a bleed mouth 10.

This specific embodiment simple structure is easy to make, and effectively dedusting, desulfurization are purified flue gas, reduce the pollution to atmosphere.
