Abstract
The invention relates to a boiler which is used for incinerating household garbage and generating steam to be used for steam supply and electricity generation. According to the technical scheme, the waste incineration boiler with a furnace dedusting device comprises a steel frame, a boiler chamber and a fire grate, wherein the boiler chamber is composed of a hearth, a burned ash chamber and three smoke flues, and a horizontal flue and a flue with a U-shaped tail portion are arranged behind the boiler chamber. By mean of the technical scheme, the compound-type waste incineration boiler is capable of guaranteeing timely drying, full burning and burning out of the household garbage which is low in calorific value, high in moisture and high in ash specification and effectively reducing flying ash amount in smoke.
Description
Technical field
The present invention relates to a kind of boiler that steam is used for steam supply, generating that house refuse is burned and produced.
Background technology
In recent years, China's industry fast development, population is concentrated in a large number, and the city Rapid Expansion causes house refuse more and more.The improvement of rubbish has become current very urgent, the problem that can't avoid.Adopt garbage burning processing method, can effectively reduce the rubbish capacity, save the soil, be difficult for producing and pollute, and can produce steam and be used for steam supply, generating.
In view of the advantage of waste incineration on " minimizing, innoxious and resource ", now become the main flow mode of garbage disposal.The composition of the main component of flue gas of refuse burning, exhaust gas volumn and rubbish, combustion system, fume treatment auxiliary etc. are relevant.For burning domestic garbage better and effectively reduce flying dust amount in the flue gas, so completely newly developed compound garbage burning boiler.
Summary of the invention
The objective of the invention is to design a kind of house refuse of guaranteeing low heat value, high moisture content, ash-rich in time dry, fully burn and burn and effectively reduce the garbage burning boiler of the flying dust amount in the flue gas.
Realize above-mentioned purpose, the present invention adopts following technical scheme: have the garbage burning boiler of dedusting in stove device to include steelframe, furnace chamber and fire grate, wherein furnace chamber is made up of burner hearth, burning chamber and three flues; The U-shaped flue of horizontal flue and afterbody is set behind the described furnace chamber.
The further setting of the present invention is: arrange ∑ type convection tube device and high temperature superheater in described three flues, described ∑ type convection tube device includes tedge, down-comer, convection bank and recirculation pipe, wherein the two ends up and down of tedge and down-comer are connected with the collection case of drum and convection bank respectively, tedge becomes " 7 " shape, down-comer is oblique setting for one section near drum, close next part case is for one section vertically to arrange, and tedge and down-comer adopt aforesaid way to be provided with and be beneficial to the water circulation; The whole one-tenth of described convection bank " ∑ " shape, convection bank is provided with recirculation pipe along three flue lateral arrangement between the last next part case of convection bank; Medium temperature overheater and low temperature superheater are set in the described horizontal flue.
Of the present invention further the setting again is: ∑ type convection tube device and high temperature superheater are installed in described three flues, and ∑ type convection tube device adopts independently closed circuit; In the middle of the bottom ash bucket of the U-shaped flue of described afterbody the grooved separator is installed.
By adopting such scheme, the present invention/invention has the following advantages:
1, upper furnace is installed the water-cooled partition wall, and the partition wall down-comer of drawing from the drum hydrospace supplies water to the water-cooled partition wall, and the steam water interface that the heat absorption back forms enters drum from the carbonated drink fairlead of partition wall top outlet collection case.The layout of water-cooled partition wall can increase the radiation heating-surface of burner hearth, improves the boiler caloric receptivity.
2, arrange ∑ type convection tube device and high temperature superheater in three flues, take full advantage of space in three flues, shorten the length of horizontal flue effectively.∑ type convection tube device can make smoke distribution even, and reduces the superheater input gas temperature, avoids the superheater coking.∑ type convection tube device has recirculation pipe, and adopts independently closed circuit, and is safe.The whole one-tenth of convection bank " ∑ " shape can be arranged more heating surface in limited space.
3. ∑ type convection tube device and sectionalized superheater place arrange steam sootblower, and the economizer place arranges the shock-wave ash blowing device, can effectively remove the dust stratification of heating surface, improve heat exchange efficiency.
4. in the middle of the bottom ash bucket of the U-shaped flue of afterbody the grooved separator is installed.The resistance of grooved separator is little, and easily manufactured, easy layout is installed, and it is little to take up room, and the blast damage is little, and can effectively separate oarse-grained flying dust, reduces the flying dust amount in the flue gas.
5. the U-shaped flue of afterbody can reduce the back-end ductwork height, takes full advantage of the space, makes the boiler structure compactness.
Below in conjunction with accompanying drawing the present invention is further described.
