Description
Technical field: the utility model relates to vapourizing furnace, particularly a kind of novel no tar discharging stalk gasifier.
Background technology: stalk gasifier furnace bottom air feed deficiency of the prior art, inhomogeneous, insufficient so burn, unstable, furnace bottom often occurring burns empty, burn, aerogenesis is not died, and is flame-out, reduced the result of use of fuel, the gasifying stalk combustion gas contains a large amount of gaseous state tar, vaporous water solves tar at present, water mainly adopts washing, spray, biomass are filtered three kinds of methods, the coke discharging of lowering the temperature exactly of the principle of these methods, tar is separated from gas, as waste discharge, both waste the energy of tar itself then, seriously caused secondary pollution again.
Summary of the invention: the purpose of this utility model is to provide a kind of novel no tar discharging stalk gasifier, this vapourizing furnace utilizes the charcoal of vapourizing furnace self output as catalyzer, the heat that self produces is as heating source, realize the high-temperature catalytic cracking by the physical structure in the stove, this stove in using continuously, the gas production rate abundance, coke tar cracking is abundant, no longer include secondary pollution discharging, both saved the energy, real again environmental protection.
Formation of the present utility model: by urceolus, thermal insulation layer, compressing rod, feeding pressure mechanism, the charging opening sealing cover, sealing-ring, base, the deslagging flap, ash discharging hole, an inlet mouth, the secondary oxygen supply port, eddy flow tray, venting port is formed, in the urceolus the inside is thermal insulation layer, venting port and deslagging flap are arranged on urceolus, compressing rod one end is a screw mandrel, the other end is installed handle, screw mandrel lower end at compressing rod is a feeding pressure mechanism, on compressing rod, charging opening sealing cover and sealing-ring are installed by the silk mouth, at the top of compressing rod the binder handle is arranged, feeding pressure mechanism places in the urceolus, the charging opening sealing cover is installed on the charging opening by the fastening card of sealing cover, eddy flow tray is installed on base below the burner hearth, in eddy flow tray one side the secondary oxygen supply port is arranged, the secondary oxygen supply port is communicated with an inlet mouth of base one side, the air outlet opening that distributes on the blade at eddy flow tray top has ash discharging hole and ash discharge lid below base.
The spiral vane that epirelief is arranged in the middle of the eddy flow tray, the angle between each blade are 85 degree.
Compared with the prior art, the utility model uses 85 degree eddy flow tray air feed, is provided with ash discharging hole in the eddy flow tray bottom, is convenient to ash discharge, and the whole bottom of vapourizing furnace air feed is even, sufficient combustion, and gas production rate is good and stable.Thermal insulation layer can improve temperature in the stove, the charcoal that utilizes vapourizing furnace self output is as catalyzer, the heat that self produces is as heating source, realize the high-temperature catalytic cracking by the physical structure in the stove, experimental results show that: this stove in using continuously, the gas production rate abundance, coke tar cracking is abundant, no longer include the secondary pollution discharging, both saved the energy, realized environmental protection again.
