Abstract
The invention relates to a direct-fired half-gasification downdraft type full-gasification multifunctional straw furnace, belonging to the technical field of cooking and warming equipment. The furnace is innovatively characterized by the invention of a duplex circulative purification device, wherein the device comprises a horizontal slope cross board, a vertical cross board, a staggered round hole and a round disk-type drier purifying mechanism. The furnace is further innovatively characterized by the design of a triple ash cleaning device which can clean furnace ash thoroughly, conveniently and fast. The straws of crops are utilized to produce a combustible gas, the combustible gas is circularly purified and filtered to remove impurities and tar and further enhance the quality of fuel gas and improve cooking and warming effects, thus, the environmental pollution is reduced, and the problems of the traditional gasification furnaces that the quality of the produced gas is poor, the emission of waste gas is too much, the furnace is not available during power failure and in case that the straw is wet, the tar is difficult in processing and the combustible gas has peculiar smell are solved. The straw furnace of the invention realizes stable gas production, good availability during power failure and in case that the straw is wet, good quality of fuel gas, no peculiar smell in the combustible gas, no pollution and the like, can be extensively applied to household cooking, water heating, warming and the like in urban and rural areas, and has extremely wide market prospect.
Description
One, technical field
The present invention relates to a kind of direct combustion full gasification multifunctional stalk furnace of downdraft that partly gasifies, belong to cooking, heating system technical field, can be used for that town-dweller-rural-family cooks, heats up water, heating etc.
Two, background technology
At present, the operation principle of China's family expenses stalk gasifier is updraft type and downdraft and direct combustion half gasification.Above stove using method and function singleness, though having carried out small lot in some areas promotes the use of, but because of this stalk gasifier unreasonable structure, can not use thereby aerogenesis instability, poor, the moist fuel of combustion gas quality have in use occurred, incomplete combustion, easily produce tar and exhaust emission environment, it is big that peculiar smell is easily revealed in combustion gas, power failure can't be used, and has had a strong impact on applying of this technology.Thereby cause stalk gasifier slower development in the popularization process, have quite a few and stopped use, thereby caused worse influence socially.
Three, summary of the invention
The objective of the invention is to solve the existing existing problem of stalk gasifier technology, improve the gasifying stalk effect, solve the problem that toxic emission is many and the tar processing is difficult and the calm function of moist stalk fuel is used.The invention provides a kind of novel direct combustion downdraft stalk furnace that gasifies entirely that partly gasifies, by to furnace binding, the innovation and creation of suction and furnace bottom cleaning mechanism have changed the flow direction of fuel gas, and have purified in cyclic process under decontamination cycle, the combustion gas, improved combustion gas quality, automatically separate tar and moisture in the fuel gas, do not need the bell sealing, the fuel gas free from extraneous odour, there is no waste gas and discharge, can on a stove and accessory, realize the course of work of full gasification or half gasification.Stove and accessory is provided with water tank, can make full use of waste heat, output hot water used in everyday automatically, and can be used as heating and use.In the furnace bottom innovative design pull out apparatus for ash, can make ash discharge convenient, fast, reliably reduce the labour.Therefore, this stove can be realized cooking, heat up water, multinomial functions such as heating.
Research and design of the present invention a kind of novel direct-fired half gasification and full gasification using downdraft furnaces tube, adopted the pot type structure, under when inhaling full gasification mode and using, aditus laryngis place, burner hearth bottom fire grate top is the Pintsch process combustion zone, charge door is an air inlet, utilizes induced-draught fan to make gas downflow be transported to burner combustion.
Direct combustion half gasification mode uses, stove can normally use under power failure and stalk material humidity, fuel is in the burner hearth internal combustion, the air that the up fresh air inlet with the charge door burner port below of fuel gas that produces enters fully mixes directly in the burning of charge door burner port, and stalk gasifies entirely or the function of half-gasification oven thereby have.
Research and design of the present invention a kind of novel gas purifier, adopted horizontal slope cross board, square crossing plate, disk cross bore, bottom that the water surface and paddle dryer treatment facilities are arranged, thereby combustion gas is filtered through multistage purification, can purify tar in the fuel gas and moisture filter clean, in addition in whole gas-purification route, airtight sealing, thus the leakage of combustion gas and waste gas avoided, and treatment facilities mechanism is installed in and produces daily hot water when using in the water tank simultaneously.When using, direct combustion half gasification also can produce daily hot water simultaneously when using because water tank links to each other with burner hearth.
Research and design of the present invention novel downdraft gas circuit, the gas of stalk gasifier output, under the air-breathing effect of induced-draught fan, combustion gas is through a S undulation, through moving both vertically several times and water surface collision, through once intensive circular hole formula formula motion, pass through the filler Filter dryer at last, thereby improved the gas-purification effect.
Research and design of the present invention a kind of novel furnace bottom ash discharging gear, adopt three times the ash discharge structure, be provided with drawing and pulling type deashing bar at the fire grate place, pull can be removed part ashes in the burner hearth back and forth, fire grate connection handle can thoroughly be cleared up lower floor to the inner of the boiler chamber ash smoothly by turning handle and deposit the ash place, lower floor adopts circular hole formula deashing pull plate, below the pulling pumping board can be fallen ashes in the hole outside the stove by Da Yuan on the pumping board, ash accepting box is arranged below the stove, simple to operate, minimizing labour, quick and easy, deashing is thorough.
The invention has the beneficial effects as follows: this direct combustion full gasification multifunctional stalk gasifier of downdraft that partly gasifies, novel structure, creativity and innovation gas-purification EGR, downdraft combustion gas closed circuit, furnace bottom ash-clearing structure and half gasification of collection direct combustion and the seamless entire combination of the full gasification of downdraft.Has purity simple to operate, as to have improved fuel gas, removed tar and the moisture in the fuel gas, and can realize safe and reliable pollution-free, do not choose material, there is electric power or not can both use, use stalk to be raw material, improve the straw utilization rate, help reducing the environmental pollution that crop straw burning causes, can be widely used in family's cooking, heat up water and heating etc.Have higher promotional value, market prospects are wide, still find no or similar techniques identical with the present invention at present at home and abroad.
