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

1. Technical field [0001] The invention relates to a direct-fired semi-gasification downdraft full-gasification multifunctional straw stove, which belongs to the technical field of cooking and heating equipment and can be used for cooking, heating water and heating in urban and rural families. 2. Background technology [0002] At present, the working principles of domestic straw gasifiers in my country are updraft, downdraft and direct combustion semi-gasification. The use method and function of the above stoves are single. Although they have been popularized and used in small batches in some areas, due to the unreasonable structure of this kind of straw gasification furnace, the gas production is unstable, the gas quality is poor, and the wet fuel cannot be used during use. , Incomplete combustion, easy to produce tar and waste gas to pollute the environment, easy to leak gas and have a strong odor, and cannot be used in a power failure, which has seriously affected the pop...
