Background technology
Boiler miscellaneous in the market, its mechanism is generally arrange specific flue, and then the place of flue approach arranges water tank, thus is heated by water, utilizes water, object that vapour reaches heating.Boiler in the market take coal as the more of fuel.The coal-burning boiler had a large capacity and a wide range will consume a large amount of coal, the coal-smoke pollution source that Ye Shi China is main simultaneously.General vertical fire coal normal-pressure hot-water boiler, primarily of shell end socket, flue, flue top, lower seal, impact tube and horizontal water tube composition, combustion chamber placement is in flue, fuel burns on fixed grate, gravity-flow ventilation, flue gas is transversal flow horizontal water tube in flue, enters air through impact tube, chimney.The heat utilization efficiency of general boiler is relatively low, there is the problems such as the heating surface area water yield that is not enough, heating is few of the too high waste energy of smoke temperature, water.In addition, the dedusting of boiler is directly be discharged in air mostly, and coal ash dust wherein causes brokenly ring to neighbouring environment, and air quality is declined, also cannot cycling and reutilization.
Summary of the invention
The object of the present invention is to provide a kind of energy-saving dedusting boiler, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of energy-saving dedusting boiler, comprise support, water inlet pipe and dust arrester, on described support, side is provided with boiler body, boiler body is provided with the first water tank, combustion chamber and coal ash collecting room, coal ash collecting room is arranged at the below of combustion chamber, on combustion chamber, side is connected with smoke exhaust pipe, smoke exhaust pipe runs through the second water tank, the inside that smoke exhaust pipe is positioned at the second water tank is multiple-way duct structure, the upper end of smoke exhaust pipe is connected with dust arrester by flue gas exit pipe, described dust arrester comprises interior pipe, outer tube, blast pipe, pond and air-introduced machine, interior pipe is provided with in described outer tube, interior pipe connects blast pipe, blast pipe is through outer tube wall, exhaust outlet is placed in air, one end of described inner and outer tubes is closed, the other end is placed in pond and interior pipe is provided with an air inlet in position at surface of water, described flue gas exit pipe is connected with outer tube, flue gas exit pipe is provided with air-introduced machine.
As the further scheme of the present invention: described first water tank is different from the volume of the second water tank.
As the further scheme of the present invention: described smoke exhaust pipe is positioned at the second water tank and is at least 3 road pipelines.
As the further scheme of the present invention: described basin bottom is provided with slag-drip opening.
Compared with prior art, structure of the present invention is simple, reasonable in design, by smoke exhaust pipe being run through in the second water tank, the heat of smoke exhaust pipe can be made full use of like this, the water yield of this boiler heating can also be improved simultaneously, coal resource is utilized more fully, save coal resource, in addition, flue gas burning produced is input to the inside of dust arrester by flue gas exit pipe, the waste residue that dust arrester can will produce in boiler combustion process, dust carries out precipitation process, due to waste residue, the precipitated process of dust, the coal ash dust being discharged into air is considerably less, ring is not formed brokenly to neighbouring environment, air quality is up to standard, and the cinder after precipitation can be carried out cycling and reutilization.
