Description
Technical field:
The invention belongs to the biomass garbage process field, particularly a kind of is main biomass garbage pyrolyzer system in order to handle domestic refuse.
Background technology:
The biomass resource storage is very abundant, as a kind of renewable energy source, its reasonable use, not only can alleviate environmental pressure, also can avoid the transition of traditional coal, fossil fuel is relied on, cracking technique can be converted to inflammable gas with biomass and biomass garbage, as replenishing of the energy, generate electricity, comprehensive utilization such as heat supply, also be the at present main direction of utilizing.
Moreover process of urbanization when having improved people's living standard, has also increased the burden of domestic refuse, and this also is global a great problem.The mode of tradition landfill is still also being used, and there is obvious defects in emerging incineration treatment of garbage, and the dioxin gas of its generation can't thoroughly be eliminated, and combustion processes also needs certain fuel combustion supporting.At present, though the test subject that various places have the rubbish cracking to burn all is that some experimental exploration shapes are.And another kind of biomass garbage burning disposal promptly is the mode that adopts Pintsch process.
As patent announcement CN100338396C, be called the pyrolyzer of heating in the rubbish, its structure is by pedestal, body of heater is installed on the pedestal, the top of body of heater is provided with the air outlet, the place, side of body of heater is provided with an opening for feed, and the place, another side of body of heater is provided with inlet mouth, and the inquiry bottom of body of heater is equipped with the arch fire grate; The pedestal inner bottom part is fixed with main shaft, and the upper end of main shaft rises up into the fire grate top of body of heater and rotating turret is installed, and knife is installed on the rotating turret; Pedestal is at the interlayer that is provided with 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.During work from the inlet mouth input air, rubbish promptly can produce cracking under sultry state, rubbish enters through automatic drying from opening for feed and dewaters when entering working cycle, after drop to gasification layer gasification, drop to the zone of cracking cracking again, then drop to layer of carbon, the carbon slag is discharged by deslagging device by the fire grate hole.This patent has provided the notion of a waste cracking furnace, but each link is all perfect inadequately, and such as opening for feed, the encapsulation process that there is no need causes gas leak; The arch fire grate of bottom of furnace body can play a supportive role to rubbish, but only designs one deck fire grate, can't support the rubbish weight in the whole body of heater, to such an extent as to rubbish is closely knit in the body of heater, is unfavorable for the burning of the garbage carbonized thing of bottom; Moreover aspect deslagging, design also lacks perfect.
Patent announcement CN201196486Y, be called and the supporting gas emission processing system of domestic refuse pyrolyzer, its structure is that heat in the rubbish top of pyrolyzer is provided with collection chamber, the side of collection chamber is connected with vapor pipe, the other end of vapor pipe is connected to oil, gas separates the resorption jar, oil, gas separate resorption jar upper end and are provided with the combustion gas vent pipe, and the lower side is provided with oil exit pipe; The other end of combustion gas vent pipe is connected to the combustion gas storage cabinet, and the other end tracheae of combustion gas storage cabinet directly is connected to the combustion gas internal combustion engine generator; The centre of oil exit pipe is connected with oil sump and oil pump, and the other end pipeline of oil pump directly is connected to the lower end, cracking furnace side of heating in the rubbish.The characteristics of this patent promptly are by an oil, gas separating treatment, and oil is as the combustion-supporting oil of reignition, and cracked gas can make full use of the renewable energy resources as the fuel of gas electricity generator.This patent just provides a generalities design, and the possibility of realization is not high, and by the high-temperature gas mixture that pyrolyzer gives off, directly enters oil, gas separation, also is difficult to reach the ideal purpose.
The technical schemes of also open many relevant waste cracking furnaces mostly are exploratory scheme greatly in the patent gazette, and poor operability is difficult to satisfy the need of actual production.It is reasonable how to invent a kind of scheme, and the comprehensive pyrolyzer that structure is feasible promptly becomes the object that the present invention studies.
Summary of the invention:
The objective of the invention is to invent that a kind of furnace sealing feed, blanking can evenly be supported, sufficient combustion, produce clean inflammable gas, reduce the biomass garbage cracking system that produces secondary pollution in the production process.
Technical solution of the present invention is achieved in that a kind of biomass garbage pyrolyzer system, comprises body of heater, feed mechanism, connects the slag container, scrubber tower, gas-oil separation tower and gas collection tower; Upper of furnace body is provided with feed mechanism, top and connects that scrubber tower, middle part are provided with fire grate, the bottom is provided with paddle, goes out wind apparatus and scum pipe; Fire grate and paddle is characterized in that respectively by power wheel drive:
A) body of heater: the middle part is provided with the above fire grate of one deck, and every grate furnace row is formed side by side by the fire bars of an above hollow structure, and the intravital fire bars of stove surface becomes the spiricle structure at least, and this spiricle offers breach, and breach is to offer along the axis parallel direction; Bottom center is movably equipped with power shaft, power shaft stove inner end is fixed with the paddle of selecting a structure of cross section triangulation shape or semicircle arcuation, wherein the bottom surface of paddle is parallel with furnace bottom, power shaft and paddle are hollow structure, offer the downward-sloping production well of outlet on paddle two central planes or the semicircle cambered surface;
B) feed mechanism: comprise hopper, feed bin and the feed opening that is communicated with body of heater from top to bottom successively, this feed bin upper/lower terminal is respectively equipped with movable flashboard;
