103 First air of gasification furnace is that the flue gas generation certain pressure of high-temperature blower extraction incinerator 104 blasts gasification furnace 103 In the corresponding air compartment 107 in 105 lower section of stoker fired grate formula moving hearth, then by an air holes spray on moving hearth 105 Rubbish is shot through, is gasified, wind supply quantity is adjusted by the first regulating valve 207 on each arm of correspondence.103 Secondary Air of gasification furnace Be high-temperature blower extract incinerator 104 flue gas produce certain pressure blast 103 burner hearth of gasification furnace, its spray-hole is arranged on gasification On 103 face arch of stove and rear arch.Secondary confession air port 115 is provided with forward and backward arch, gasification efficiency is improved, strengthen macromolecule in flue gas Substance decomposition.Igniting combustion supporting hole 114 is had on rear arch, and in furnace lifting, baker and stable gasification furnace 103, temperature is used, by correspondence The first regulating valve 207 on each arm adjusts wind supply quantity.The air inlet of second blower fan 203 and material pit atmosphere, the The air that two blower fans 203 are blasted can be cold wind or the hot blast after heating.The gas outlet connection the of second blower fan 203 The house steward of two manifolds 205, the arm of second manifold 205 each First air respectively with 104 moving hearth of incinerator, 105 lower section The inlet end of room 107 and dust arrester 201, outlet side connection, are respectively provided with second on each arm of second manifold 205 Regulating valve 208.104 First air of incinerator is that air blast blasts the air of certain pressure under stoker fired grate formula moving hearth 105 In the corresponding air compartment 107 in side, then by an air holes spray penetration residue on moving hearth 105, residual burning is carried out, Wind supply quantity is adjusted by the first regulating valve 207 on each arm of correspondence.The inlet end of dust arrester 201, the air intake of outlet side are Temperature adjustment air feed, temperature adjustment air feed are that the air of certain pressure is blasted incinerator 104 and exports (i.e. cyclone inlet) by air blast Temperature adjustment is carried out, meanwhile, Cyclone outlet (i.e. high-temperature blower entrance) blasts further temperature adjustment, by each arm of correspondence First regulating valve 207 adjusts wind supply quantity.

Circulation air feed system to the waste disposal method after stoker fired grate formula refuse gasification incinerator air feed, the method press with Lower step is carried out：

Step A, closing stoker fired grate formula refuse gasification incinerator 1 and the gate of atmospheric vent, start mechanical grate-type rubbish Rubbish incinerator 1, garbage raw material is put into feed hopper 102, and the pusher back and forth of garbage pusher device 106 will be from feed hopper 102 The garbage raw material for falling pushes the windrow seal section 108 between feed hopper 102, gasification furnace 103, is formed windrow seal section 108 Windrow sealing state, unnecessary rubbish fall into the moving hearth 105 of gasification furnace 103, and the moving hearth 105 of gasification furnace 103 works, Rubbish is conveyed into transition fall slag section 109, the pusher back and forth of residue pusher 110, the transition rubbish in slag section 109 that falls is pushed away Enter in incinerator 104, the work conveying garbage of moving hearth 105 of incinerator 104, until rubbish is in gasification furnace 103, incinerator 104 moving hearth 105 is accumulated to required thickness：0.6-0.8m, during baker, the rubbish that is piled up can protect mobile stove Bed 105, prevents scaling loss siege 105.Stop feeding intake to feed hopper 102, the moving hearth 105 of gasification furnace 103 and incinerator 104 stops Only work, then, with start-up burner by the igniting combustion supporting hole 114 of gasification furnace 103 and incinerator 104 respectively with gasification furnace 103 and the burner hearth of incinerator 104 communicate, in the presence of start-up burner, gasification furnace 103 and incinerator 104 are carried out furnace lifting, Baker, treats that this process stabilization is completed, and makes gasification furnace 103 and 104 burner hearth of incinerator reach 600-700 DEG C of predetermined temperature；Baker Purpose be in order to remove the Natural Water in lining and the crystallization water, in order to avoid when going into operation as furnace temperature rises too fast, moisture content is a large amount of Expansion causes body of heater spalling, bubbling or deformation even furnace wall to collapse, and affects intensity and the service life of heating furnace furnace wall.

Step B, startup adjust circulation air feed system 2, adjust gasification furnace 103, incinerator 104 and circulation air feed system 2 Technological parameter (pusher speed, fire grate speed, wind-warm syndrome, blast and an air quantity, secondary air temperature, blast and air quantity, furnace temperature, Negative pressure, thickness of feed layer etc. in stove), feed intake to feed hopper 102, the work conveying garbage of moving hearth 105 of gasification furnace 103, rubbish Burning is proceeded by the burner hearth of gasification furnace 103, and rubbish residue is piled up at transition falls slag section 109 to form windrow sealing, makes The stove chamber inner combustion state temperature of gasification furnace 103 is stabilized to more than 850 DEG C, the work output combustion of moving hearth 105 of incinerator 104 Rubbish residue after cinder.

Step C, each technological parameter for adjusting gasification furnace 103, incinerator 104 and circulating air feed system 2 (pusher speed Negative pressure, thickness of feed layer in degree, fire grate speed, wind-warm syndrome, blast and an air quantity, secondary air temperature, blast and air quantity, furnace temperature, stove Deng), gasification furnace 103 gradually gasifies to rubbish, and gasification temperature is stable between 700-800 DEG C, so that gasification furnace 103 is stably produced The raw high-temperature flue gas containing 10%-20% synthesis gas, it is equal that 103 vaporized state of gasification furnace stably carries out low temperature, middle temperature or high-temperature gasification Can.Make 104 fired state temperature stabilization of incinerator to more than 850 DEG C, realize rubbish continuous gasification burning disposal；Need to adjust simultaneously Each technological parameter of cyclone dust removal room 3, makes 304 temperature stabilization of the 3rd exhanst gas outlet of cyclone dust removal room 3 to more than 850 DEG C.

Step D, need to overhaul or during blowing out, stop feeding intake, adjust gasification furnace 103, incinerator 104 and circulation air feed system 2 technological parameter, makes gasification furnace 103 be gradually restored to fired state, after rubbish and rubbish residue burn, closes stoker fired grate Formula refuse gasification incinerator 1 and circulation air feed system 2.Each technological parameter of cyclone dust removal room 3 need to be adjusted simultaneously, make gasification furnace 103 are gradually restored to fired state.

Finally illustrate, preferred embodiment above is only unrestricted in order to the technical solution of the utility model to be described, to the greatest extent Pipe is described in detail to the utility model by above preferred embodiment, but those skilled in the art should manage Solution, can make various changes, in the form and details without departing from the utility model claims institute to which The scope of restriction.
