Description

Through-flow type phase-splitting reverse-burning gas generator

Technical field

The invention belongs to a kind of coal-gas producer, particularly a kind of through-flow type phase-splitting reverse-burning gas generator.

Background technology

Existing coal-gas producer is by the producer body, is located at the fire grate of bottom in the producer body and the sealing pond that is located at below the producer body constitutes, on the producer body, be provided with blast inlet, gas exit, coal feeding hole and slag notch and explosive door, and blast inlet is located at below the fire grate, its coal-adding type is the coal at intermittence, and producer gas process is to carry out from the bottom to top.This coal-gas producer exists following drawback and hidden danger: 1, in order to ensure enough blast, the strict sealing of the air feed of coal-gas producer, because producer gas process carrying out from bottom to top, can only adopt water to seal, the fervid coal that leaks down during burning also can only fall into the water, and causes imperfect combustionly, and thermosteresis increases, thermal load sharply descends, and has a strong impact on the normal operation of equipment.2, in actual motion, interlaced, uneven between each bed in the producer body, cause the coal gas composition and the coal gas generating capacity time to time change that produce, when zone of oxidation rises to the surface, just become the naked light combustion phases, because thickness of coal seam and ventilation can not be even everywhere, thereby naked light burning is not to begin simultaneously along whole surface, always burns in some part earlier, forms fire hole, extended surface causes coal gas to interrupt then; Coal of the coal-gas producer of gap coal needs 4--5 hour ability after-flame, and gasification only accounted for for 1/3rd left and right sides times.3, equipment is cumbersome, and is bulky, and the consumption steel material is big, the cost height, and its cost even be higher than boiler body, efficiency of combustion is low, and labor strength is big when slagging tap, and therefore existing producer is used seldom in practice.

Summary of the invention

The objective of the invention is to solve the problems referred to above that prior art exists, a kind of coal burn-off rate height is provided, energy-saving effect is obvious, no flue dust, environmental protection, safe and reliable to operation, simple in structure, volume is little, the through-flow type phase-splitting reverse-burning gas generator of low cost of manufacture, applied range.

The present invention be achieved in that the producer bodies top be positioned at coal inlet around be provided with a hollow sandwich, described blast inlet is positioned at the top of producer body and communicates with hollow sandwich, the blast inlet inlet is positioned at this external surface of producer, the blast inlet outlet communicates with the producer chamber body, and the blast inlet outlet is all established along the circumferential direction of coal inlet; Slag notch is the end mouth of producer body, gas exit is positioned at the bottom of producer body, the bottom is provided with moving grate in the producer body, below moving grate, be provided with secondary air channel, be positioned in the producer body and be the combustion chamber below the secondary air channel, the respective combustion chamber place is provided with lighting-up tuyere on the sidewall of producer body, is provided with stoker fired grate in the lower end of producer body.

Above-mentioned through-flow type phase-splitting reverse-burning gas generator, described secondary air channel are to be made of a ring-shaped round pipe and the uniform ring-shaped round pipe tube head inboard and that tilt to oblique below that is welded on.

Advantage of the present invention is: 1, producer gas process is from top to bottom carried out, exactly opposite with existing coal-gas producer, the rate of combustion of coal can reach more than 98%, the heat energy utilization rate improves greatly, unburnt red-hot coke falls into the combustion chamber, the heat radiation that burns away, and kindling material is provided for later stage coal gas, run duration is with to use other gas effect identical; 2, energy-saving effect is obvious, does not have flue gas during operation, can reach the geographic environmental requirement of a class, compares with other coal-gas producer, can save energy 8-10%; 3, adopt from top to bottom through-flow to give wind, back out of service cuts off and the contacting of oxygen automatically, guarantees the generation of noresidue coal gas in the combustion chamber, and is safe and reliable to operation; 4, delicate structure is simple, and volume is little, and manufacturing process is corresponding simple, and cost is low, can be connected with heat-exchange equipment is straight-through, makes one-piece construction compact more, and steel quantity consumption descends significantly, has only about 1/3rd of existing coal-gas producer; 5, have wide range of applications, can be used for non-ferrous metal metallurgy, in various industry, the civil boiler.
