Description
Affiliated technical field
The utility model relates to the agricultural crop straw comprehensive utilization, is with farming, woods, herds discarded living beings are converted into fuel gas by the reaction of limit oxygen combustion and pyrolysis a kind of gasification furnace.Especially updraft type household gasification furnace.
Background technology
At present, updraft type gasification furnace of the prior art is simple in structure because of it, cheap, stalk resource is extensive, because of global concern energy crisis with because of atmosphere polluting problems that agricultural wastes caused such as seasonal crop straw burnings, party and state pays much attention to the development and use of regenerative resource again, encourages and advocate the stalk energy, to alleviate China's energy shortage situation, strive for not only energy-conservation but also environmental protection; But, also, apply thereby restricted it often because of the condensed water spill and leakage causes secondary pollution because gasification furnace of the prior art is handled unclear blocking pipe and kitchen range because of tar; The a large amount of experiments of inventor by for many years, having submitted application number on August 10th, 2008 is 200810210412.2 patent document, has now made breakthrough improvement and raising again on its basis by development test repeatedly.
Summary of the invention
A kind of monoblock type non-coke tar stalk gasification furnace, comprise body of heater, ash hole, smoke evacuation tube, the blower fan of updraft type gasification furnace, it is characterized in that: kitchen range is arranged at that the combination of upper furnace and body of heater is in aggregates, heat up cracking Burning stove hole, closed pot frame, roof of the furnace one side is provided with that the combustion gas releasing tube that leads to the smoke evacuation tube and relief valve, body of heater middle and upper part one side are provided with charge door, burner hearth bottom is provided with manual rotation and drives grey blanking and air-intake device certainly.
After adopting minute body device to purify more, existing gasification furnace is delivered to kitchen range for burning structures by pipeline for overcoming again, thereby cause combustion gas on the way gradually the cooling make wherein tar and the deficiency of steam condensation deposition blocking pipe and kitchen range, the technical scheme that the utility model adopted is: kitchen range is arranged at upper furnace and the body of heater combination is in aggregates, make the interior vaporific combustion gas of high temperature of burner hearth need not to export burner hearth and under the hot environment of being cooled off as yet, directly enter the kitchen range burning, reached the purpose of no longer stopping up because of the condensation deposition.
The abundant cracking of tar causes the thermal efficiency lower when burning because of its kitchen range in order to overcome existing gasification furnace, on the kitchen range and on every side the tar along with the burned flame ejection spatters to such an extent that black mark is full of stains or spots, the deficiency that stink is pungent, the technical scheme that the utility model adopted is: be provided with from heating up the cracking Burning stove hole, it is that a barrel made from metal material divides tar and moisture being heated up of inside and outside multilayer to be cracked into the burner system of fuel gas, enter its structure of order by combustion gas and can be divided into first road air admission hole → combustion gas intensification cracking room → second road air admission hole → hybrid combustor, kitchen range core position is provided with combustion-supporting blast pipe → air intake intensification chamber → spray hot wind hole → hybrid combustor, show that by testing repeatedly this structure can be cracked into fuel gas with the intensification of the tar in the combustion gas, steam can be cracked into hydrogen, again with heat up after hot blast (combustion air) mixed combustion, combustion gas intensification cracking room and mixed combustion room temperature all reach more than 1000 ℃ when being in normal operating conditions, thoroughly solve the outlet of tar and condensed water, improved the thermal efficiency.
When burning, can produce a part of waste gas and not clean-burning pernicious gas in order to overcome its kitchen range of existing gasification furnace, cause room air to be got dirty and influence health, the technical scheme that the utility model adopted is: closed pot frame is set, can select for use metal material or refractory material to become the support that is used to shelve frying pan that exceeds range panel of a circle at kitchen range upper end position circle, one side or many sides are provided with one or more toxic emission holes that lead to the smoke evacuation tube, when burning, kitchen range frying pan can be held on the closed pot frame, being closed state so between the two can not leak, the pernicious gas that the combustion chamber that forces kitchen range and closed pot frame to be combined into produces when burning drains into outdoor towards the smoke evacuation tube from the toxic emission hole, guarantee that room air is not contaminated.
Cause the deficiency of room air pollution in order to overcome existing gasification furnace when reinforced in the burner hearth outside the combustion gas meeting ejection stove taking off lid, the technical scheme that the utility model adopted is: be provided with combustion gas releasing tube and the relief valve that leads to the smoke evacuation tube in roof of the furnace one side, when need are reinforced if open earlier relief valve with burner hearth in combustion gas drain into outdoorly through the smoke evacuation tube, and then take off lid and feed in raw material and just do not polluted.
The beneficial effects of the utility model are by kitchen range directly is arranged at upper furnace, have reached no longer the purpose because of condensation deposition blocking pipe and kitchen range eye; Be provided with from the cracking Burning stove hole that heats up can thoroughly solve tar and condensed water pollution problem, improved the thermal efficiency, eliminated pungent smell; Closed pot frame can force pernicious gas to discharge outdoor from the smoke evacuation tube; Be provided with the combustion gas of leading to smoke evacuation tube in roof of the furnace one side and discharge releasing tube and relief valve, can solve and take off lid and do not have combustion gas when reinforced and spray, guaranteed that room air is not contaminated, ensured to use safely and do not influence health; By being set at burner hearth bottom, manual rotation drives grey blanking and air-intake device, from then on do not reburn the sky cutoff, can drive grey blanking, guarantee normal combustion aerogenesis easily, eliminated trouble and worry, by improving, make product ripe more, help applying of energy-saving and emission-reduction and new socialist countryside construction.
