Abstract
Description
Technical field
The present invention relates to a kind of sludge incinerator, relate in particular to the sludge incinerator of the wet mud of a kind of direct burning.
Background technology
Municipal sewage treatment produces a large amount of mud, in the enterprise production process such as papermaking, food, chemical fibre, also produces a large amount of mud, and rubbish Anaerobic Treatment can produce a large amount of mud equally.In mud, contain a large amount of bacteriums, worm's ovum, heavy metal and organic matter etc., if dealt with improperly, can cause new pollution.
A large amount of mud in reality are without processing by outdoor placement, severe contamination environment, and taken a large amount of soils.The common processing method of mud is to adopt landfill method, and the method causes secondary pollution to soil and groundwater again.Sludge Composting is also a kind of method of lignin-sludge, but cost is higher, thereby the heavy metal in mud can be absorbed by plants harmful to human, at west most countries, has forbidden using sludge manure in agricultural.
Along with scientific and technical progress, sludge incineration method becomes Treatment of Sludge method the most thoroughly.A difficult problem for sludge incineration is that moisture percentage in sewage sludge is high and mud hydrophily is stronger, moisture is difficult to remove, and no matter adopts natural seasoning, mechanical dehydration method or static evaporation, and treatment effeciency is extremely low, cannot meet the processing demands of mud at all, greatly limit applying of sludge incineration method.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of drying sludge and burning is carried out simultaneously, the wet sludge incineration stove of sufficient combustion.

As the improvement to technique scheme, relatively described frame is also installed with auxiliary material and adds auger conveyor, the feed end that described auxiliary material adds auger conveyor is positioned at outside, described tubular body of heater upper end, and the discharge end that described auxiliary material adds auger conveyor stretches to described tubular body of heater inner and upper.
As the improvement to technique scheme, the discharging opening that described auxiliary material adds auger conveyor is communicated with the upper end of described mud granulizing conveying worm inner chamber.
As preferred technical scheme, described fume extractor comprises the set chimney being fixedly mounted in described frame, the lower ending opening of described set chimney also stretches to the inner chamber of described tubular body of heater, the outer end sealing of described set chimney, and the blind end of described set chimney is provided with smoke exhaust pipe.
As the improvement to technique scheme, described upper sealing device is the stuffing seal being arranged between described set chimney and described tubular body of heater.
As preferred technical scheme, described air-intake device comprises and is fixedly mounted in described frame and the cloth air duct of closed at both ends, the lower end of described cloth air duct is positioned at outside described tubular body of heater, the described cloth air duct being positioned at outside described tubular body of heater is provided with air intake joint, the upper end of described cloth air duct stretches to the inner chamber of described tubular body of heater, and the position of the corresponding described burner hearth of described cloth air duct is provided with the wind distributing hole being communicated with described burner hearth.
As the improvement to technique scheme, described lower sealing device is the stuffing seal being arranged between described cloth air duct and described tubular body of heater.
As the improvement to technique scheme, described air-intake device also comprises the swivel joint being sleeved on described cloth air duct outer wall, described cloth air duct outer wall is provided with the air vent being communicated with described swivel joint inner chamber, described swivel joint is connected with auxiliary blast pipe, and the outlet air end of described auxiliary blast pipe passes described tubular body of heater and is communicated with described burner hearth from outside.
As preferred technical scheme, described riding wheel apparatus comprises and is arranged in described frame and at least two pair support rollers corresponding with described tubular body of heater, and described tubular body of heater outer surface is installed with the annular holder rail corresponding with described support roller.
As preferred technical scheme, described frame is provided with at least one pair of top wheel, and described top wheel is resisted against described annular holder trackside face.
As preferred technical scheme, described body of heater rotating driving device comprises the motor being fixedly mounted in described frame, described motor power is connected with gearbox, the clutch end of described gearbox is provided with driving gear, is installed with the gear ring with described driving gear engagement on described tubular body of heater.
As preferred technical scheme, described ash exhauster comprises openable ash-draining gate.
Owing to having adopted technique scheme, wet sludge incineration stove, comprises frame, and described frame tilts tubular body of heater is installed, and riding wheel apparatus and body of heater rotating driving device are installed between described tubular body of heater and described frame, in described frame, be installed with the fume extractor coordinating with described tubular body of heater upper end, between described fume extractor and described tubular body of heater, be provided with upper sealing device, in described frame, be installed with the air-intake device coordinating with described tubular body of heater lower end, between described air-intake device and described tubular body of heater, be provided with lower sealing device, the sidewall of described tubular body of heater lower end is provided with ash exhauster, in described frame, be installed with mud granulizing conveying worm, it is outside that the feed end of described mud granulizing conveying worm is positioned at described tubular body of heater lower end, the discharge end of described mud granulizing conveying worm stretches to described tubular body of heater inner and upper, described mud granulizing conveying worm upper end is provided with steam discharger, and the discharging opening place of described mud granulizing conveying worm is provided with granulation discharge opening, between the inwall of described tubular body of heater lower end and described mud granulizing conveying worm outer surface, be provided with burner hearth, the upper end of described mud granulizing conveying worm is fixedly connected with described fume extractor, described mud granulizing conveying worm stretches to described tubular body of heater inner chamber, in the course of conveying of mud, mud is concentrated, semiarid mud is by granulation discharge opening extruding pelletization, mud granule continuous tumble dry moving to burner hearth place under the tubular body of heater of rotation drives, to burner hearth place, become incendivity particle, thereby realize the burning of mud, it is concentrated for mud that the heat of sludge incineration partly offers mud granulizing conveying worm, the flue gas producing after burning carries part heat and by fume extractor, is transferred to energy utilization and smoke eliminator together with water vapour, extract the energy clean discharge, compact conformation of the present invention, mud concentrate drying efficiency is high, does not waste energy, and sludge incineration is thorough, has thoroughly solved the technical bottleneck of sludge incineration, has great economic and social benefits and application value.
