Abstract
The utility model relates to a low-suction type organism-gasifying furnace, which is a gasifying device for organism containing carbon. The utility model can generate large amounts of combustible gas. The low-suction type organism-gasifying furnace is composed of an upper-section burning chamber, a middle-section gasifying chamber, a lower-section sealed ash-removing chamber, etc. The lower-section sealed ash-removing chamber uses a non-water sealing structure, and a shell body uses a water jacket type for preventing the corrosion of the high-temperature flammable gas to the shell body. The lower part of the shell body is provided with a sealing door for removing the ash regularly. The utility model has the advantages of compact structure, convenient operation, no tar and waste water and environment protection. The generated flammable gas can be sent to gas cabinets and pipe networks after being purified by a gas cleaning device.
Description
The utility model belongs to biomass gasification device, particularly from wood chip, straw, contain the device that obtains a large amount of inflammable gass the solid biomass such as carbonaceous industrial waste.
Chinese patent CN902108433 discloses a kind of novel biomass gasifying device, and its compact construction is convenient to advantages such as installation, transportation, long working life, but because its vapourizing furnace hypomere adopts hydrolock, waste water contains the easy contaminate environment of tar.
The object of the present invention is to provide a kind of operation, intermittent dust removal, downdraft biomass gasification device of no tar and waste water be convenient to.
The related downdraft biomass gasifying furnace of the utility model in general each cross section is garden shape, by epimere combustion chamber (3), stage casing vaporizer (2) and hypomere sealing dedusting chamber (1) three part are formed, connect with bolt between each section, top, downdraft biomass gasifying furnace epimere combustion chamber (3) is provided with opening for feed (6) and lighting door (5), and feeder is sent into the carbon containing biomass material in the gasifier by opening for feed.Epimere combustion chamber (3) is a chuck of being made up of shell (8) and interior cover (7), on shell (8) top several gas inlets and valve (4) are set evenly radially, be disposed radially several nozzles (9) in interior cover (7) bottom, make the air admission chuck give the heat back and enter downdraft biomass gasifying furnace epimere combustion chamber for the material burning by nozzle (20).Downdraft biomass gasifying furnace stage casing vaporizer (2) is a metal shell (10), and the outer casing inner wall bottom is welded with a loop bracket (13), and loop bracket has mesh, and the vaporizer inwall of being made by refractory materials (11) is set on carriage.Vaporizer inwall bottom has a ring-like chamber of hollow (12) to communicate with air outlet (17).Downdraft biomass gasifying furnace hypomere (1) has housing and the fire grate (14) that is fixed on the housing, and fire grate can be other fire grates in fixed grate, the manual fire grate.The utility model downdraft vapourizing furnace housing is made by steel plate, in order to prevent the corrosion to housing of high-temperature combustible gas that vaporizer (2) produces, shell is set to water jacket formula (15) with preliminary cooling inflammable gas in downdraft biomass gasifying furnace hypomere sealing dedusting chamber (1).Housing is one and is water jacket (15) with steel welding; it in the housing dedusting chamber (11) with external world's sealing; be provided with a hermatic door (16) in its underpart; instantly absorbing biomass gasification furnace is in when moving under the negative pressure state; biomass are constantly fallen into sealing dedusting chamber (12) by the last a small amount of ash quarrel of gasification, and open hermatic door and remove institute's dust stratification and be cut when accumulating to shut down when a certain amount of.Removed and shut the hermatic door operation of starting shooting again after the ash quarrel, assurance downdraft gasifying biomass furnace bottom is in the strict seal state, and inflammable gas is leaked.The high-temperature combustible gas body that the utility model stage casing vaporizer (2) produces concentrates on the ring-like chamber in the refractory materials after air outlet (17) are sucked out through the carriage mesh, sends into gas holder and pipe network after gas purifying equipment purifies.
The utility model has the advantages that hypomere adopts water jacket sandwich type element high-temperature corrosion resistance, the life-span is long, and is dry ash removal, does not contain tar and waste water, and is easy and simple to handle.
