Abstract

Structure of the cracking furnace includes following parts: gas outlet in top of furnace body installed on base; entrance port in one side of furnace body, and air inlet in other side, and arched fire grate on bottom part; knives on rotational knife rack installed on principal axis possible to be raised to above the fire grate; in upper part of barrier bed, chained kick plates for remove out dregs. In operation, gas containing 60% oxygen through air inlet enters into furnace. Under condition of sultriness, the cracking of garbage is carried out. In operation cycle, following procedures are processed: feeding garbage, automatic drying dehydration, down to gasification layer to be gasified, gasified garbage lowered to layer of carbon removed out by slag tap mechanism. Gas generated from cracking is reclaimed.

Description

The pyrolysis furnace of heating in the rubbish
Technical field
The present invention relates to the device of garbage disposal, a kind of specifically rubbish is implemented the pyrolysis furnace of heating in the rubbish that cracking handles.
Background technology
At present, the processing of application of city life garbage mainly contains methods such as landfill, separation and burning.Landfill is land occupation not only, and pollutant exists forever, and can cause nonvolatil influence to the environment such as water source of landfill periphery; Separation is a kind of very elaboration, promptly needs with machinery, again must be by manually carrying out compounding practice, and also the land occupation area is big, engineering is also big, some refuses still need to handle; Burning is the good method that solves refuse pollution, but its investment is big, and new pollution the such as the flue gas that produces in the burning, waste water, noise, stench, residue is difficult to solve, and particularly the dioxin that produces in the burning process etc. is threatening seriously pollutedly that people's is healthy.
Show that from the domestic and international interrelated data retrieval that comprises Chinese patent at present rubbish being implemented the cracking processing is following main direction, but do not see the report of its maturation.Chinese patent application has " domestic garbage cracking treatment device and technology " (application number: 01139744.6) in openly announcing, " cracking furnace and corollary apparatus thereof " (application number: 02131325.3) all introduced the rubbish cracker, but all be horizontal pyrolysis furnace.It is big that horizontal equipment has a floor space, defectives such as equipment complexity.
Summary of the invention
Adopt horizontal equipment in order to overcome conventional garbage processing cracking, the big and complex structure and other problems of floor space the invention provides the pyrolysis furnace of heating in a kind of novel vertical garbage.
The technical solution adopted for the present invention to solve the technical problems is: the pyrolysis furnace of heating in a kind of novel vertical garbage is characterized in that: a pedestal is arranged, the waste cracking furnace body is installed on the pedestal, described waste cracking furnace body is made up of shell and internal layer; The top is heat-insulation layer on the described body of heater, and the heat-insulation layer top of body of heater is provided with the gas outlet, and body of heater is provided with a charging aperture at the place, side by the top, and body of heater is provided with air inlet at the place, side by pedestal, and the bottom of body of heater is equipped with an arch fire grate; Centre bottom is fixed with a vertical spindle in the pedestal, and the main shaft skin is with the refractory material cover, is with the cast iron cover between main shaft and the refractory material cover, and the side of main shaft is equipped with motor and chain; The upper end of main shaft rises up into the fire grate top of body of heater and a rotating turret is installed, and knife is installed on the rotating turret; Pedestal is at the interlayer that is provided with a sealing by the upper end of body of heater, and the upper end of interlayer is equipped with the deslagging device that chain scraper drives.Described support and body of heater can be circle, quadrangle, pentagon, hexagon, octagonal; Described fire grate endoporus is square, rectangle, hexagon and circular net formula; Described body of heater shell is that steel are made; Described body of heater internal layer is that refractory material is made; Closure insulation is made for the perlite material on the described body of heater; Described rotating turret is two kinds on an oblique frame peace frame; Described knife is two kinds of barbed knives of sheet cutter and pole.The gas that contains 60% oxygen during work from the air inlet input, rubbish promptly can produce cracking under sultry state, rubbish enters through automatic drying from charging aperture and dewaters when entering working cycles, after drop to gasification layer gasification, drop to the cracking zone cracking again, then drop to layer of carbon, the carbon slag is discharged by deslagging device by the fire grate hole.The gas that the rubbish cracking produces in working cycles promptly can reclaim as pipe gas, generates electricity Application in Chemical Engineering, synthetic ammonia application etc.Described its temperature of rubbish cracking is controlled within 1000~1300 degree; The described circular treatment time that at every turn enters rubbish is 40~80 minutes.
The invention has the beneficial effects as follows: because the present invention has adopted vertical unit, therefore, floor space is little, and simple and practical, also therefore cracking process has formed a kind of benign cycle from top to bottom naturally, therefore, can be divided into drying layer in this device, the gasification layer, cracking zone, fire bed and layer of carbon.In addition, the present invention need not fuel, is to utilize input to contain the gas of 60% oxygen, utilize rubbish heat of vexed in stove, carries out the nature cracking.Secondly, the gas of the present invention's generation is that alkane hydrogen class can be used in industry and civilian fully; Carbon slag of the present invention also can be used to do brick or fill out road etc.Therefore, the present invention is a kind of rubbish processing to be harmless, realizes a kind of good method of zero-emission.
Description of drawings
The present invention is described in more detail below in conjunction with drawings and Examples.
Fig. 1 is the pyrolysis furnace structural representation of heating in the rubbish of 240 tons of day disposals of refuse of the present invention.
1 pedestal among the figure, 2 bodies of heater, 3 shells, 4 internal layers, 5 heat-insulation layers, 6 gas outlets, 7 charging apertures, 8 fire grates, 9 main shafts, 10 refractory material covers, 11 cast iron covers, 12 motors, 13 chains, 14 rotating turrets, 15 knives, 16 interlayers, 17 deslagging devices, 18 drying layers, 19 gasification layers, 20 cracking zones, 21 fire beds, 22 layer of carbons, 23 air inlets.
