Description

Directly the burning faggot the Multifunctional high-efficiency civil air-conditioner

Technical field

The utility model is a kind of Multifunctional high-efficiency civil air-conditioner of direct burning faggot.

Background technology

Coal, oil, natural gas are non-renewable conventional energy resources, and reserves on earth reduce day by day, and its price is more and more expensive, cause many countries that the energy security of self is more and more paid attention to; Its main manifestations is to utilize new energy technology, exploitation straw, branch, the agriculture and forestry organic waste materials such as weeds of growing thickly, these fuel and conventional coal ratio, its advantage is to regenerate every year, and various places are easy to get, and is cheap, it is little to use the process environmental pollution, and shortcoming is that phosphorus content is less, and calorific value is low; Volatile component is high, and lower temperature is separated out, and easily ignites, and not anti-burning need frequently be dosed fuel, and the available loss of energy is large, and thermal effect is low; Density is little, and is lightweight, and volume is large, gives transportation, stores and bring certain difficulty.Burning produces a large amount of tar, is difficult for removing and utilizing etching apparatus, contaminated environment; The general cooking stove of problem that above-mentioned biomass fuel exists is difficult for solving.

The purpose of this utility model is, solves above-mentioned existing existing problem, and a kind of Multifunctional high-efficiency civil air-conditioner of direct burning faggot is provided.

The utility model is achieved in that in the bottom of host housing and connects main machine base, host housing is provided with the ash door, connect fire bars in the host housing in the middle of bottom connecting partition, the dividing plate, is connected lower heat exchanger tube between dividing plate and the orifice plate, thus formation lower combustion chamber, hot air chamber, grey chamber; Hot air chamber is provided with hot-blast outlet; Form upper combustion chamber between orifice plate and the up-hole plate, orifice plate and up-hole plate are connected with air heating pipe, heat exchanger tube, consist of airflow path between host housing and the heat exchanger tube, upper combustion chamber is communicated with what transfer the cigarette valve and enters a heatable brick bed smoke pipe, the upper and lower part of upper combustion chamber is connected with the backflow heat exchanger tube, in the host housing, top is connected with feeding tube, water seal urceolus, top installation loam cake, consists of tank between feeding tube and the water seal urceolus; The feeding tube middle part communicates with upper combustion chamber, forms the passage that feeds intake, and consists of cold air chamber between feeding tube and the host housing, and cold air chamber is provided with cold air inlet.Be connected with heat exchanger tube and communicate with upper combustion chamber with the upper smoke tube of transferring the cigarette valve; Be connected with flame retardant coating in upper heat exchanger tube, lower heat exchanger tube inboard; Combustion chamber installation smoke barrier suitable for reading, fire bars is connected with secondary wind inleting tube.

The utility model has the advantages that, adopt smoke barrier, backflow heat exchanger tube syndeton, fundamentally changed traditional combustion mode and the heat exchange mode of general fuel; The fuel gas such as CO of the latent heat of vaporization of water vapour, tar, not combustion are all recycled, and then improve the thermal efficiency, energy-saving and emission-reduction.Function is many: hot wind supply, and burn simultaneously a heatable brick bed, remove loam cake, smoke barrier, make pot and can heat up water, cook; Fuel is selected face width, and the various combustibles such as rice husk, sawdust, bagasse reach the stock things such as corn stalk, branch as long as brachymemma just can directly be used, and time saving and energy saving, cost is low.
