Abstract
The invention provides a double-bed sludge gasification furnace, which comprises a screw extrusion forming device, a drying chamber and a gasification chamber. The double-bed sludge gasification furnace is characterized in that: the upper part of the drying chamber is provided with a feeding inlet and a gas outlet, wherein the feeding inlet is connected with the screw extrusion device; baffles with a downward slope are arranged in the drying chamber; the baffles are staggered opposite to each other; the lower part of the drying chamber is connected with a feeder; rotatable feeding vanes are arranged in the feeder; an outlet of the feeder is connected with the upper feeding inlet of the gasification chamber; a tower type multipolar grate is arranged in the gasification chamber; the lower part of the tower type multipolar grate is provided with an air inlet; a lateral part of the gasification chamber is provided with a working hole, and the lower end of the gasification chamber is provided with an soot door; and a gas pipeline is arranged between the upper part of the gasification chamber and the lower part of the drying chamber. The double-bed sludge gasification furnace has the advantage of converting discarded municipal domestic sludge to be processed as trashes serving as raw materials into usable energy. The double-bed sludge gasification furnace works based on the theory that drying and dry distillation and gasification are performed on separate beds. The gasification process has a high gas yield; tar generated by burning a fuel is a light tar, has a good flowability and complete combustion; and a carbocoal fuel has a good gasification condition and little loss of incomplete combustion.
Description
Technical field
The invention belongs to a kind of gasifier section, particularly a kind of with the municipal sludge gasification process make its be converted into the cleaning inflammable gas double-bed sludge gasification furnace.
Background technology
The city all can produce a large amount of domestic sludges every day, because mud moisture content complexity, great majority are combination water in the cell, and free-water is few, and mud is stacked for a long time, and the place should not solve, and the foul smelling smell.Can make it produce geseous fuel by the processing of existing fixed bed gasification furnace, the problems referred to above have not only been solved, simultaneously geseous fuel is present stage widely used cleaning, an eco-friendly power source, in heating, metallurgy, steel rolling, forging, thermal treatment and various Industrial Stoves irreplaceable effect is arranged.The conventional fixed bed gasification furnace in gasification because processes such as raw material drying, destructive distillation, gasification are all finished gasification in same gasification equipment, this gasifying process is because pyrogenous temperature height, make the fugitive constituent in the fuel when Pintsch process, generate heavy tar, this tar is mobile poor, easy blocking pipeline, the equipment of burner influences works better production.
Summary of the invention
The purpose of this invention is to provide a kind of double-bed sludge gasification furnace, the discarded municipal sludge that needs to work as refuse treatment as raw material, is converted into the available energy.
Summary of the invention
Technical scheme provided by the invention is as follows: it comprises the screw extruding briquetting device, drying shed, vaporizer, it is characterized in that: the top of drying shed is provided with opening for feed and gas exit, opening for feed connects helix extrusion device, baffle plate with downward-sloping gradient is set in drying shed, baffle plate is crisscross arranged relatively, the bottom of drying shed connects material feeder, the feed blade that can rotate is set in the material feeder, the material feeder outlet connects the upper end opening for feed of vaporizer, tower multipole grate is set in the vaporizer, the bottom of tower multipole grate is provided with blast inlet, the sidepiece setting operation mouth of vaporizer, and the lower end is provided with ash output hole; Between the bottom of the top of vaporizer and drying shed, be connected gaspipe line.
At the outer setting water jacket of vaporizer, water jacket connects the carbonated drink refrigerating unit.
Every grade of grate of above-mentioned tower multistage grate is a umbrella body, and each umbrella body is ascending successively from top to bottom, forms tower, has ventilation opening to communicate with ventilator below every grade of grate.
Advantage of the present invention is: will discard the municipal sludge that needs when refuse treatment as raw material, and be converted into the available energy.Adopt principle work dry, destructive distillation divides the bed gasification with gasification.This gasifying process gas yield is big, and the tar that fuel generates is tar light oil, and the good fluidity burning is complete, and the fuel gasification condition of semicoke state is good, and incomplete combustion loss is few.

Embodiment
See Fig. 1-4, concrete structure is as follows: the top of drying shed 11 is provided with opening for feed and gas exit 14, and opening for feed connects helix extrusion device 12 by taking over, and helix extrusion device 12 adopts existing installation, and helix extrusion device 12 front portions are provided with mud input port 13.Baffle plate 20 with downward-sloping gradient is set in drying shed 11, gradient is 45 degree, baffle plate 20 is crisscross arranged relatively, be beneficial to break up when sludge bulking falls, the bottom of drying shed 11 connects material feeder 9 by taking over, the feed blade 22 that can rotate is set in the material feeder 9, and the blades axes 21 that is evenly distributed with six feed blades 22 is by driving (not shown) by motor-driven retarding mechanism.Material feeder 9 outlets connect the upper end opening for feed of vaporizer 4, tower multistage grate 18 is set in the vaporizer 4, every grade of grate is a umbrella body, each umbrella body is ascending successively from top to bottom, forms tower, has ventilation opening 3 to communicate with ventilator 19 below every grade of grate, the ventilator bottom is provided with blast inlet, the external gas blower of blast inlet, the sidepiece setting operation mouth 17 of vaporizer, the lower end is provided with ash output hole 1; At the water jacket 16 that the outer setting of vaporizer 4 is made of inwall 6 and outer wall 5, the upper and lower ends of water jacket 16 connects cooling back installations 10 by carbonated drink pipe 7, and refrigerating unit 10 is a bucket formula container.Top in gasification Room 4 is connected gaspipe line 15 with the bottom of drying shed 11.
Equipment work principle: enter drying shed 11 by opening for feed after 12 compactings of mud raw material process screw extruding briquetting device, the moulding, when falling through staggered relatively sloping baffle 20, can make circuitous entering about material, can directly not fall device bottom and lose original geometrical shape, stick to each other and influence high-temperature gas circulation.The sludge bulking raw material is filled it up with drying shed, the fugitive constituent in the mud is volatilized under lower temperature to the greatest extent, enter into after raw material drying, the destructive distillation in the vaporizer 4, sludge bulking enters gasification, and combustion in the vapourizing furnace with the semicoke state.Materials such as the moisture in the fuel, fugitive constituent can fully be separated out like this.350~400 ℃ of high-temperature flue gas that produce in the gasification return by gaspipe line 15 that drying shed 11 recycles and from gas exit 14 outputs.The lime-ash of after-flame is discharged through vaporizer ash output hole 1, drops in the ash-pan 2.
