Affiliated technical field

The utility model relates to and a kind of organic substance is carried out the device of gasification process, and especially a kind of can the gasification to propellant combinations such as straw, xylogen and a certain proportion of domestic refuses produces the vertical organic matter gasification stove of inflammable gas.

Background technology

At present, organic waste material is carried out environmental protection treatment and efficiently utilizes is a global problem, the method that organic waste material is effectively handled mainly includes landfill, compost, gasification, pyrolysis etc., wherein gasification, pyrolysis treating method are to the comparatively thorough and efficient a kind of effective way utilized of organic waste disposal, the principle of its gasification is under the insufficient condition of oxygen supply, organism is at combustion processes generation incomplete combustion, thereby produces the thermochemical process of flammable composition and fugitive constituent.Existing its structure of straw gasification stove is to add straw in a cylindrical burner hearth, light straw from below, seal fire door then, allow straw in burner hearth, carry out incomplete combustion, thereby produce flammable compositions such as a large amount of carbon monoxide, methane, tar and in burner hearth, discharge burning, there is structural defective in this straw gasification stove, and the one, easy and mix dust blocking pipe such as the tar of discharging, the 2nd, continuously long-time result of use is poor.

Summary of the invention

Too simple in order to overcome existing gasification furnace structure, operation inconvenience, deficiency difficult in maintenance, the utility model provides a kind of vertical organic matter gasification stove, and not only compact construction is reasonable for it, and operation is reliable, safeguard simple and easyly, and can effectively handle organic domestic waste and hospital refuse.

The technical scheme that its technical problem that solves the utility model adopts is: an inlet pipe is set in the bottom of vapourizing furnace, one end of inlet pipe passes body of heater and is connected with blower fan, the other end passes body of heater and links to each other with secondary oxygen supply pipe, be provided with the gasification point inlet mouth that raises up at the middle part of inlet pipe, be provided with an on limits ash discharge plug with secondary oxygen supply pipe coupling end, upper interior portion at the vapourizing furnace body of heater has one section skirt shape inner bag, between the inwall of skirt shape inner bag and vapourizing furnace certain clearance is arranged, the interface of vapor pipe and gas line and vapourizing furnace is positioned at the furnace wall, top that is with skirt shape inner bag, the vapourizing furnace upper opening is an opening for feed, sealing cover covers opening for feed, is provided with tank between sealing cover and the opening for feed and is used for airtight opening for feed.

The beneficial effects of the utility model are, can be at full speed and the organic waste material of gasification process expeditiously, and compact construction is reasonable, operation is reliable, safeguard simple and easyly, can effectively handle crop stalk, organic domestic waste and hospital refuse, part solves the fuel problem of life, boiler etc.
