Said ventilation venthole 06 is preferably circle, ellipse, square, rectangle, triangle or fillet rectangle, can also be other figure.
The hole direction of principal axis of said ventilation venthole and said body of heater axially be the 30-60 degree.
Advantage of the present invention:
The present invention has three big advantages: minimizing, and innoxious, resource.
Minimizing: can reduce to about 10% of former water-containing sludge quality.
Innoxious: as, to utterly destroy the possible environmentally hazardous pathogen of institute through burning; Thoroughly elimination also farthest reduces the land resource consumption that produces because of landfill because of landfill mud to the potential pollution that underground water brings; Thoroughly eliminate and behind improper processing mud, go back the potential harm that the field comes for the food chain belt.
Resource: the application of the invention is to the processing of mud, and its energy demand can be closed circulation, and the unnecessary heat that system produces can be used for generating electricity, and is used for the need for electricity of Sewage Plant.
A kind of under-oxygen heat of the present invention is separated annular sludge incinerator when sludge incineration, need not to add other disposable energy substance, and like coal, oil, natural gases etc. only need a spot of electric energy, can reach mud and independently burn.After mud came out from dewater unit, dehydration reached 50%-40% from 80% water content once more, gets into incinerator of the present invention then.Application of the present invention fundamentally solves mud besieged city quagmire.Mud does not go out the sewage-farm and can properly be disposed in principle, has save the Environmental costs that other processing modes such as mud cost of transportation and landfill cause.After project is built up, the operation cost of sewage treatment plant be can practice thrift greatly, environmental pollution and cost of transportation that the mud transportation brings reduced.Floor space of the present invention is little, and disposable input is low, and efficient is high.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
A kind of under-oxygen heat is separated annular sludge incinerator, comprises body of heater 02, also comprises furnace bottom 28; Condenser 19 and blower fan 21, the top of said body of heater is provided with bell 01, and the middle part of said body of heater is provided with ventilation venthole 06; The bottom of said body of heater is provided with air vent 10; The periphery of the middle and upper part of said body of heater is surrounded with toroidal combustion chamber 05, and the top of said toroidal combustion chamber is provided with exhaust opening 03, and the bottom of said toroidal combustion chamber is provided with dust stratification feeder 29; Said dust stratification feeder is provided with ash disposal mouth 07; Outer wall at toroidal combustion chamber is provided with at least one air feed tuyere 15, and said blower fan is connected with said air feed tuyere through air feed pipe 16, and said air feed pipe is provided with first air-valve 17;
Said furnace bottom comprises loop vent chamber 08 and tubular draft chamber 11; Said loop vent chamber is around the periphery of the bottom that is arranged on said body of heater; Said tubular draft chamber be arranged on said loop vent chamber below, fire grate 12 is arranged on the middle part of said tubular draft chamber, the bottom of said tubular draft chamber is provided with slag notch; Be provided with fire grate carriage release lever 13 below the said fire grate, said fire grate carriage release lever is connected with fire grate mobile device 14;
Periphery in top, toroidal combustion chamber, loop vent chamber and the tubular draft chamber of said body of heater is provided with insulating layer of furnace body 04;
The top of said condenser links to each other with the top of said body of heater through pipeline, and said condenser is connected with said blower fan through backwind tube 24, and said backwind tube is provided with second air-valve 23; The bottom of said condenser is provided with condenser discharge outlet 20;
Said blower fan is connected with said tubular draft chamber through furnace bottom air feed pipe 25, and said furnace bottom air feed pipe is provided with the 3rd air-valve 18.
Said ventilation venthole 06 is preferably circle, ellipse, square, rectangle, triangle or fillet rectangle, can also be other figure.
The hole direction of principal axis of said ventilation venthole and said body of heater axially be the 30-60 degree.
When the toroidal combustion chamber air feed, the angle of air feed tuyere setting can make air feed be the rotation shape to blower fan through air feed pipe and air feed tuyere, and rotating air feed can increase combustible in the indoor time of staying of annular firing, makes burning more abundant.The pressure reduction that the rotation air feed produces between the inside and outside wall of toroidal combustion chamber, the flue gas entering toroidal combustion chamber that helps in the body of heater burns, and the gas that the burning back produces is discharged from exhaust opening.
The present invention operates for the first time: open bell; Successively matches such as timber, coal briquette are filled into body of heater, fill sludge ball or the mud granule (following general designation mud granule) that contains quality 40%-50% then, light timber; Burning along with following timber and coal briquette; Top mud granule toward moving down, is treated the coal briquette afterburnt under the effect of gravity, is all filled by mud granule in the body of heater; Temperature in the body of heater reaches (through temperature control system) behind the system requirements, under the effective control to air feed and temperature, can keep continuation in the device of the present invention and burn.In the stove material---the mud granule moving process is following: mud granule slowly gets into the middle and upper part (oven dry bringing-up section) of body of heater, middle part (volatilization pyrolysis section) along with following timber, coal briquette burning; Middle and lower part (carbonization pyrolysis section); Furnace bottom (dust stratification section) starts the fire grate mobile device, moves fire grate; Through removing the cinder notch slagging-off, accomplish a combustion process.Through in body of heater, supplying mud granule continuously, keep the continuation of burning.
Blower fan is given tubular draft chamber and loop vent chamber air feed through furnace bottom air feed pipe, and part wind is carried under one's arms flue gas from ventilation venthole entering toroidal combustion chamber, and some continues upwards to get into the middle and upper part of body of heater; Large quantity of moisture in the mud is evaporated; Water vapour gets in the condenser, and condensed water is exhausted from system and returns sewage treatment plant, and remaining air gets into blower fan through backwind tube; Form one and close circulation, avoid the diffusion of smell.
Toroidal combustion chamber has dust and produces, and the dust stratification feeder that the bottom through toroidal combustion chamber is provided with is collected dust, again through the regular dedusting of ash disposal mouth.
Be positioned at body of heater of the present invention toroidal combustion chamber the middle and lower part the position an observation window can also be set, be beneficial to observe the situation of material burning in the body of heater.
Under-oxygen heat of the present invention is separated annular sludge incinerator and is mainly used in municipal wastewater treatment plant and part trade effluent treatment plant, and a large amount of mud that sewage treatment plant produces every day is handled and disposed to occasions such as soot through the method for thermal decomposition.The present invention also can be applicable to handle organic matter and other suitable organic matters of disposing through thermal decomposition in the municipal refuse with the method for thermal decomposition.It is a kind of heat utilization method of brand-new organic waste.
