Description

A kind of steady flame slide materials device

Technical field

The present invention relates to a kind of steady flame slide materials device.

Background technology

Coal slime oven dry industry flourish along with in recent years, for providing good development, the energy development strategy of country supports, solved the stacking of coal washing industry coal slime, pollution problem, and exchanged the regeneration of a large amount of waste resources for less cost, coal slime drying plant industry also is flourish in recent years, but the problem that exists on the structure, equipment performance is uneven, configuration varianceization is big, use not fully up to expectations, the producer gas self-ignition temperature is 650 degrees centigrade, if the front portion does not install fixed combustion chamber similar device additional, in the course of the work, dryer is anterior because the appearance of water vapour and the reason of kiln tail air inducing, can not guarantee that there is high-temperature region more than 650 degrees centigrade in the dryer front portion, then producer gas is very easily because of reasons such as coal mechanically actuated or gas quality instabilities, cause under the duty frequently flame-out, in addition, build by laying bricks or stones with refractory brick because of the traditional combustion chamber is many, exist volume big, quality is heavy, heat insulation effect is not good, it is slow to heat up during start, cooling is slow during shutdown, and civil engineering is many, difficulty of construction is big, and be difficult for and problems such as roller drier docks, the stoving process of high moisture material, usually adopt co-current mode, just flame sprays into cylinder from feed end, tremie pipe is as slipping the necessary device of expecting so, its refractoriness just goes through one's facings greatly, tremie pipe has the material of employing to have now: stainless steel, heat resisting steel, earthenware, common A3 steel or the like, wherein earthenware is not suitable for the operating mode of gas generator, the work characteristics of producer gas is a quick heating, cooling is fast, as easy as rolling off a log causing of suddenly cold and hot bursts concerning pottery, damage very fast, stainless steel, cost is too high again with the heat resisting steel material, and scaling loss is still kept away unavoidably, only can how with several days than common iron, the slide material pipe of 12 millimeters thick A3 steel matter is exposed in the flame of producer gas, only just can wholely burn fully in 20 days, service time is very short, though cost is low, but change difficulty, thus improvement and innovate imperative.

Summary of the invention

At above-mentioned situation, for overcoming the prior art defective, the present invention's purpose just provides a kind of steady flame slide materials device, can effectively solve under the duty frequently flame-out, life-span is short, and volume is big, quality is heavy, heat insulation effect is poor, intensification is slow when starting shooting, cooling slowly when shutting down, difficulty of construction is big and difficult problem of docking with roller drier.

The technical scheme that the present invention solves is; the protective layer that the useful refractory concrete of the front end of stack shell is made; inlet plenum is arranged in the protective layer; the interior heat-resistant layer that useful ceramic fibre is made on the stack shell inwall; in the interior heat-resistant layer is hot room; hot room and inlet plenum are connected, and the material of slide pipe is arranged in the rear portion of stack shell, and the periphery of expecting pipe of slipping is enclosed with the outer heat-resistant layer made from ceramic fibre.

The present invention is in light weight, high insulating effect, and it is fast to heat up, lower the temperature, and the life-span is long, efficiently solves frequent flame-out problem under the duty.

Description of drawings

Fig. 2 is a structure right view of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated.

Provide by Fig. 1-Fig. 2; structure of the present invention is; the protective layer 2 that the useful refractory concrete of the front end of stack shell 5 is made; inlet plenum 4 is arranged in the protective layer; in the interior heat-resistant layer 1 that useful ceramic fibre is made on the stack shell inwall, interior heat-resistant layer is hot room 6, and hot room and inlet plenum are connected; the material of slide pipe 8 is arranged in the rear portion of stack shell, and the periphery of expecting pipe of slipping is enclosed with the outer heat-resistant layer made from ceramic fibre 9.

There is the feeding mouth 7 that stretches out stack shell the upper end of described slide material pipe 8, and the rear portion that hot room places stack shell is passed through stack shell in the lower end of slide material pipe; Described feeding mouth 7 is small top and big bottom infundibulate; The shape of described protective layer 2, size and stack shell match and answer, and reinforcement 3 is arranged on the front end of protective layer; Described reinforcement 3 has 3, on the front end face that is fixed on protective layer triangular in shape; Described inlet plenum 4 is big hood-like in the little rear end of front end; Described stack shell 5 is the cylinder of hollow; Described ceramic fibre also can select for use mullite firebrick, mullite pouring material, high alumina refractory casting material to replace.

During use, the inlet plenum front end places on the gas vent of mixed gas burner 11, the size of the gas vent of the size of inlet plenum front end and mixed gas burner is complementary, the rear end of slide material pipe places in the front end of dryer 10, install the steady flame slide of the present invention materials device additional, can form high-temperature region more than 800 degrees centigrade in the cylinder front portion of dryer, prevent that coal gas is frequent down in working order flame-out, even if it is flame-out in short-term, also can be because of the existence self-ignition at once of high-temperature region, in of the present invention, outer heat-resistant layer also can adopt standard HLGX-289 type aluminum silicate ceramic refractory fibre module masonry (also available mullite firebrick, mullite pouring material, refractory ceramic fibre waters material feeding, indefinite form high alumina refractory casting material, high-purity type ceramic fibre module, high alumina type ceramic fibre module, containing zirconium type ceramic fibre module replaces), gross weight of the present invention is no more than 2.5 tons, can before dispatching from the factory, finish equipment assembling, only need hoisted in position to on-the-spot back, significantly reduced the engineering time, the present invention is the ceramic fiber blanket parcel of the slide of A3 steel matter being expected effective ceramic fibre system, toast with the bonding back of HLHG-20 high-temperature agglomerant that flue company in Jinan produces, avoided the oxygen enrichment high-temperature flue gas directly to contact with the slide material pipe of steel, the outer heat-resistant layer of ceramic fibre system (claiming integument again) plays adiabatic and muffle effect, and the inner core of slide material pipe temperature under the dual-cooled of cold air and band water wet stock is difficult to bring up to more than 500 degrees centigrade, the scaling loss of the slide materials device that this just reduces greatly, and then its life-span is improved more than 6 times, prolonged the conventional maintenance time interval of equipment.
