Abstract
The utility model relates to an environment-friendly smoke discharging device of a boiler. The smoke discharging device consists of a chimney and a water-smoke mixing chamber. The water-smoke mixing chamber is arranged outside the chimney connected with the boiler. The top part of the water-smoke mixing chamber is connected with the chimney. The smoke discharging device can generate a natural extraction force to continuously burn coal and effectively prevent the discharge of dust, without any increase of installation cost and occupied area or any environment pollution.
Description
Technical field
The utility model relates to a kind of boiler environmental protection fume extractor.
Background technology
At present, the vertical boiler chimney directly is contained on the impact tube, and dust and sulfide after the coal burning directly drain into atmosphere from chimney, pollute very serious.For vertical boiler, existing cleaner is installed come what may, has all influenced the natural draft of boiler chimney, and then the influence burning, and cost and floor space are installed and used in increase.
Summary of the invention
The purpose of this utility model provides a kind of boiler environmental protection fume extractor, and this device can produce the nature draft, makes the coal continuous burning, stops dust to be discharged effectively, does not increase installation cost and floor space, and is free from environmental pollution.
The purpose of this utility model is achieved in that this device device is made up of chimney and shredded tobacco for water pipes gas mixing chamber.The outside of the chimney that links to each other with boiler is a shredded tobacco for water pipes gas mixing chamber, the chimney top is the smoke backflow cover fixedly, micropore current endless tube is arranged in the smoke backflow cover, and the dedusting feed pipe penetrates shredded tobacco for water pipes gas mixing chamber and communicates with the micropore current endless tube that passes the smoke backflow cover, and shredded tobacco for water pipes gas mixing chamber top is connected with chimney.
Chimney of the present utility model can produce the nature draft, makes the coal continuous burning.Dedusting feed pipe and micropore current endless tube can be continuously or are supplied with shredded tobacco for water pipes gas mixing chamber running water intermittently, and water drenches behind the smoke backflow cover, form cascade, make dust sink to shredded tobacco for water pipes gas mixing chamber, stop dust to be discharged effectively, and simultaneously, aqueous vapor is dissolved a large amount of sulfide.The dust that the smoke backflow cover forms coal burning back falls into shredded tobacco for water pipes gas mixing chamber after the smoke backflow cover stops.Shredded tobacco for water pipes gas mixing chamber is used to be filled with water, and preferably adds lime water, well dissolved sulfide.Airtight overflow pipe can be discharged unnecessary water, makes shredded tobacco for water pipes gas mixing chamber horizontal plane remain at same plane, and air tight.The cigarette ash sewage draining exit can be got rid of the lime-ash that sinks.
Describe concrete structure of the present utility model in detail below in conjunction with accompanying drawing, but structure of the present utility model is not limited to shown in the accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Among Fig. 1, device of the present utility model is made up of chimney 3 and shredded tobacco for water pipes gas mixing chamber 4.The outside of the chimney 3 that is connected by ring flange with boiler is shredded tobacco for water pipes gas mixing chambers 4, the sidepiece of shredded tobacco for water pipes gas mixing chamber 4 has airtight overflow pipe 2, side bottom that cigarette ash blow-off pipe 1 is arranged, chimney 3 tops are smoke backflow cover 5 fixedly, micropore current endless tube 6 is arranged in the smoke backflow cover 5, dedusting feed pipe 8 penetrates shredded tobacco for water pipes gas mixing chamber 4 and communicates with the micropore current endless tube 6 that passes smoke backflow cover 5, and shredded tobacco for water pipes gas mixing chamber 4 tops connect chimney by ring flange 7 screws.
