Description
Technical field
The utility model relates to a kind of boiler of steam 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 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 way 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 the flying dust amount in flue gas, therefore completely newly developed compound garbage burning boiler.
Summary of the invention
The purpose of this utility model be 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 flue gas.
Realize above-mentioned purpose, the utility model adopts following technical scheme: have the garbage burning boiler of internal dust-removing device for furnace to include steelframe, furnace chamber and fire grate, wherein furnace chamber is comprised of burner hearth, burning chamber and three flues; The U-shaped flue of horizontal flue and afterbody is set after described furnace chamber.
Further setting of the present utility model 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 header of drum and convection bank respectively, tedge becomes " 7 " shape, down-comer is oblique setting near one section of drum, near one section of lower header, be vertically to arrange, tedge and down-comer adopt aforesaid way to be provided with and are beneficial to water circulation; The whole one-tenth of described convection bank " ∑ " shape, convection bank, along three flue lateral arrangement, is provided with recirculation pipe between the upper lower header of convection bank; Medium temperature overheater and low temperature superheater are set in described horizontal flue.
Of the present utility model 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, groove profile segregator is installed.
By adopting such scheme, the utility model/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 formed after heat absorption enters drum from the carbonated drink fairlead of partition wall top outlet header.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, effectively shorten the length of horizontal flue.∑ type convection tube device can make smoke distribution even, and reduces the superheater input gas temperature, avoids the superheater coking.∑ type convection tube device is with recirculation pipe, and adopts independently closed circuit, 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 shock wave soot blower, 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, groove profile segregator is installed.The resistance of groove profile segregator is little, and easily manufactured, easy layout is installed, and takes up room little, and the blast damage is little, and can effectively separate oarse-grained flying dust, reduces the flying dust amount in flue gas.
5. the U-shaped flue of afterbody can reduce the back-end ductwork height, takes full advantage of space, makes the boiler structure compactness.
Below in conjunction with accompanying drawing, the utility model is further described.
