Specific embodiment
With embodiment, the concrete structure of the present invention, operation method and implementation are discussed in detail below in conjunction with the accompanying drawings
State.
As shown in figure 1, the present invention includes vaporizer 1, sealing feeder 2, gas exit 7 and streamlined air-distribution device 3.Close
Envelope feeder 2 is two-stage sealed feeder unit, and positioned at the top of vaporizer 1, the coal after granulation enters vaporizer 1 from top.Gas
Change room 1 and arrange air-distribution device more than two from top to bottom, to be passed through oxidant and gasifying agent.The top of vaporizer 1 is mainly heat
Xie Qu, by adjusting the amount of oxidant (air or oxygen-enriched) or gasifying agent (air/oxygen-enriched+vapor), makes pyrolysis zone temperature control
System is at 300-600 DEG C.The bottom of vaporizer 1 is then gasification zone, and the vaporizer surrounding of gasification zone is refractory material, is stored with more preferable
Heat, passes through to adjust the quantity delivered of gasifying agent simultaneously, makes gasification zone temperature be 600-1000 DEG C.Coal first vaporizer 1 top with
There is pyrolytic reaction in oxidant or gasifying agent, generate pyrolysis gas and tar.Tar or part are pyrolyzed gas and carry descending, or part
Stick to carbon residue or not completely on the coal of pyrolysis, be persistently pyrolyzed in the presence of oxidant/gasifying agent.Pyrolysis gas are walked downwards,
There is gasification reaction with the gasifying agent being passed through vaporizer 1 bottom, the tar of adhesion also continues to cracking, gasification.Gasify in vaporizer 1
Coal gas afterwards and carbon residue are all advanced into down grit chamber 6, gasify further and are completely gasified as far as possible with reaching, and slag indoor temperature is
1000-1100℃.The gas exit 7 from grit chamber side for the reacted coal gas enters subsequent purification collection system, and slag then passes through
Water sealed tank 6 discharges.To ensure the seal of system under the liquid level of grit chamber's outlet at bottom insertion water sealed tank.In order to prevent cinder with coal
Gas discharges gas exit 7 together, arranges baffle plate 4 before gas exit 7, angle γ < 45 ° of baffle plate 4 and vertical direction.For preventing gas
Road blocks, and baffle length l is that is, lateral projection's height of baffle plate is less than gas exit height with the relation of gas exit height h
Half.
Air-distribution device is streamlined air-distribution device 3.As shown in figure 3, streamlined air-distribution device 3 by wind-distributing pipe 8 and with cloth wind
Manage tangent streamlined upper cover 9 to form, because air-distribution device is arranged on vaporizer 1 space, for preventing coal on air-distribution device
Pile up, streamlined upper cover 9, by outside Mechanical Driven, can be axle around wind-distributing pipe centrage, turn clockwise or revolve counterclockwise
The angle turning is 0-15 °.It is provided with more than 2 groups air holes groups along tube length direction, every group of air holes group is by two wind on wind-distributing pipe 8
Hole 10 forms, and two air holes 10 are located at the same cross section of wind-distributing pipe 8, with the vertical line through wind-distributing pipe 8 center of circle for axis of symmetry offside
It is arranged in the both sides of the same cross section of wind-distributing pipe 8, angle β < 90 ° of two air holes 10 centrages.Oxidant/gas through configuration
Agent is sent into vaporizer 1 from wind-distributing pipe, is more uniformly provided and delivered by air holes 10, air holes gas speedwFor 0.5-2m/s.Vaporizer 1 is empty
Between the vertically streamlined air-distribution device of flow setting least one set 3, every group of streamlined air-distribution device 3 comprise more than 2 same height
The streamlined air-distribution device 3 of degree arrangement, so can farthest realize cloth wind uniformity and good gas-solid mixing.Air holes
10 are arranged under streamlined upper cover 9 blocks, and can avoid coal grain blocking aperture, affect uniform air distribution.
Vaporizer 1 bottom crimp forms grit chamber 5, arranges grate plate 11 in contraction place, grate plate 11 lower section is grit chamber 5.Grate plate 11
It is made up of the waveform furnace roller 12 of more than 2.Furnace roller 12 includes furnace roller central canal 13 and waveform outside plate 14.Furnace roller 12 central canal
13 is water-cooled or forced air cooled tube, and water or air flow in furnace roller central canal 13 to reach the purpose of cooling furnace roller 12, and furnace roller 12 is with stove
The centrage of roller center pipe 13 is axle, is becoming with furnace roller horizontal plane to do counterclockwise or up time in the range of 0 ~ 45 ° under Mechanical Driven
Pin rotates.Adjacent two furnace roller 12 direction of rotation are contrary, in relative motion, make the cinder in grate plate 11 in the stone roller of adjacent furnace roller 12
Drop to grit chamber 5 under pressure and turning effort, prevent bonding in grate plate 11 for the cinder from piling up.Cinder in grit chamber 5 plays cleanser
Effect, coal gas pass through cinder when, the dirt carrying can be intercepted.
