The environment-friendly double-body biomass boiler has the advantages of being simple in structure, free of smoke, friendly to the environment, sufficient in combustion and the like.

Description

Binary environment friendly biological matter boiler

Technical field

The utility model relates to a kind of boiler, particularly relates to a kind of binary environment friendly biological matter boiler with multi-layer rotating heat exchange flue.

Background technology

At present, the following problem of ubiquity in various small-sized stove and accessorys: 1, can only burn coal, be difficult to utilize a lot of low-calorie fuel, limit fuel source, make many solid-state combustibles not only can not utilize simultaneously, become on the contrary the rubbish of contaminated environment; 2, due to for once wind entrance of plain cylindrical furnace, fuel when use in burner hearth can not fully burn, and not only causes a large amount of black smokes, and the thermal efficiency is not high; 3, flue gas flow is too short and cause the excessive problem of flue gas resistance in order to increase flue gas flow, and flue gas rises too fast, and heat transfer effect is bad; 4, smoke evacuation air-introduced machine is in the past to be all operated under the condition of high temperature, exists cost high, and maintenance rate is high, the disadvantage that spoilage is high.

Utility model content

There is defect and deficiency for solving above-mentioned prior art in the purpose of this utility model, and a kind of biomass boiler of the technology with multi-layer rotating heat exchange flue and the reverse burning of multiple spot air distribution is provided exactly.

The technical scheme adopting is:

Binary environment friendly biological matter boiler, comprise main furnace body and secondary body of heater, bottom in described main furnace body is provided with burner hearth, middle part in burner hearth is equiped with fire grate, the top that is positioned at fire grate in burner hearth is fuel chambers, the below that is positioned at fire grate is combustion chamber, the top of body of heater has main furnace body water jacket, it is characterized in that: the top that described main furnace body middle part is positioned at fire grate is equipped with multiple ventilation ducts that pass main furnace body and main furnace body water jacket, the top of described main furnace body is connected with secondary body of heater by water pipe, and be structure as a whole, the bottom of main furnace body is connected with secondary body of heater by flue tube, and be structure as a whole, the top of secondary body of heater is equiped with smoke evacuation cylinder, in secondary body of heater, be provided with Multi-layer thermal exchange rotation inner bag, between Multi-layer thermal exchange rotation inner bag and secondary body of heater, it is secondary furnace water jacket, described main furnace body water jacket is connected with secondary furnace water jacket by described water pipe, and be connected, orlop heat exchange rotation inner bag is connected with the combustion chamber of main furnace body bottom by described flue tube, and be connected, the heat exchange rotation inner bag of the superiors is connected with the smoke evacuation cylinder of secondary upper of furnace body, and be connected, each heat exchange rotation inner bag between orlop heat exchange rotation inner bag and the superiors' heat exchange rotation inner bag is all connected with fume inlet passage pipe and smoke-outlet flue pipe, and fume inlet passage pipe divides and is located at the both sides that heat exchange rotation inner bag is relative with smoke-outlet flue pipe.

Major advantage of the present utility model:

1, the utility model adopts the anti-burning technology of multiple spot air distribution, and boiler can fully be burnt, again can smokeless environment-friendly.

2, the utility model has adopted rotating heat transfer technology, has realized the heat exchange mode that fire is walked in water, and meanwhile, rotation courage heat transfer technology maximizes boiler smoke flow process, greatly reduces the exhaust gas temperature of boiler.

3, the utility model has adopted smoke evacuation spraying technique, and chimney height is significantly reduced.

4, due to abundant burning, the tar content in flue gas is very low, adds that rotation courage space is larger, and boiler seldom needs deashing in running, even if deashing is also very simple, convenient.

5, because the anti-burning technology ignition temperature of multiple spot air distribution is moderate, solved the coking problem in indivedual biomass fuel combustion processes.

Brief description of the drawings

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