Description
technical field:
The utility model relates to environmental technology field, is specifically related to a kind of dangerous waste incinerator arranging device.
background technology:
Along with the fast development of China's economy, industrial prosperity, creates a large amount of hazardous wastes, causes serious pollution to environment, and country also increases pollution control dynamics.In Hazardous Waste Burning Dispose Processes, the research of dangerous waste incineration technology and improve most important.
Domestic dangerous waste incineration technology mainly adopts the incineration technology of " rotary kiln+dual firing chamber ", experiences drying, pyrolysis successively, burn and burn four-stage in incinerator.Hazardous waste enters in rotary kiln, along with the rotation of rotary kiln ceaselessly rotates rolling and moves forward in kiln, fully mix with First air, dried rapidly and generating gasification of burning in oxygen debt environment, thus enter dual firing chamber and burn under secondary wind action, the lime-ash after burning is got rid of through slag remover.But there is certain defect in the incineration technology of " rotary kiln+dual firing chamber ", require that hazardous waste composition is kept in balance, calorific value keeps stable, and require can not be too large into stove volume of material, air distribution is reasonable, otherwise in stove, refuse easily burns the problem of not cinder and coking.
For above problem, my company is through studying for many years, in conjunction with foreign technology, the basis of " rotary kiln+dual firing chamber " incineration technology is improved, fire grate device has been set up at rotary kiln afterbody, add the air distribution that reasonably burns, the problem of not cinder and slagging is fired in effective solution, reaches the code requirement of slag clinker ignition loss < 5%.
utility model content:
For the problems referred to above, the technical problems to be solved in the utility model be to provide a kind of reasonable in design, easy to operate, safe and reliable, can meet continuous effective run dangerous waste incinerator arranging device.
A kind of dangerous waste incinerator arranging device of the present utility model, it comprises housing, push rod, wind isolation board, connecting rod, ash bucket, adjustablely to take turns, steel bracket, fixed grate bar, moving grate bar, fluid pressure drive device, billy gate, fire grate balladeur train; One end of described outer frame bottom is provided with steel bracket, the opening part of housing is provided with fire grate balladeur train, the bottom of housing is provided with ash bucket, and is provided with wind isolation board between ash bucket, and push rod activity is plugged in the sidewall of housing, push rod front end is connected with billy gate, billy gate is connected with fluid pressure drive device, and the front side of billy gate is provided with connecting rod, and connecting rod is connected with fire grate balladeur train, be provided with adjustable wheel between connecting rod and fire grate balladeur train, fire grate balladeur train is provided with fixed grate bar, moving grate bar.
As preferably, described fixed grate bar, moving grate bar interval laminate into stepped arrangement, and angle of inclination is 15 ~ 20 degree.Moving grate bar is front-rear reciprocation movement under the drive of balladeur train, and the residue promoted on fire grate travels forward.The special heat-resisting alloy cast steel of fire grate strip adoption is closely poured into a mould and is formed, and having corrosion-resistant and resistant to elevated temperatures performance, being equipped with the installation accuracy through strictly controlling, fire grate bar energy long-time steady operation.
As preferably, the fire grate segment of described fixed grate bar, moving grate bar adopts heat-resisting alloy steel, and fire grate set temperature test point, by the independent air feed of fire grate blower fan, can ensure that fire grate segment works at a suitable temperature, guarantee the service life of fire grate.
Described ash bucket is formed by Plate Welding, and centre arranges wind isolation board, guarantees sealing; Be provided with insulation material in ash bucket, condense to prevent lime-ash.
During the utility model operation, add fire grate incinerator in rotary kiln afterbody, dual firing chamber bottom, and configure independent combustion air for fan.On the one hand unburnt residue in rotary kiln is burnt away on fire grate, extend material burning time, until burn; Effectively can prevent slagging on the one hand.
Fire grate selects inclination reciprocating fire grate.Hazardous waste residue falls from rotary kiln, and along grate surface by front upper place slowly movement to the back lower place, air is then upwards supplied by below fire grate.In reciprocal grate running, fire grate and material have relative motion.When moving grate forwards promotes, part does not burn material and is pulled to the top that ignite material, impels the material do not burnt still to have an opportunity to burn.When moving grate rearward returns, taking back again the bottom that a part of material that ignite returns the material not yet burnt, heating not burning material.Material, being pushed in process, is constantly squeezed, thus destroys material block and grey shell, and fiery core is had an effect burning.Simultaneously material slowly rolls again, and what make to catch fire is material bedly loosened fully, has enough burning times, and prepares to meet next fire grate to move back and forth.Unburnt residue, under the double action of movable furnace grate plate and fire grate wind, can burn fast, add the burning time, reach the object burnt.
Material burns on fire grate, and combustion air supply is supplied separately by fire grate blower fan, and fire grate fan frequency conversion controls, and regulates combustion air quantity delivered with the Incineration circumstances according to material on fire grate.Owing to adding fire grate, be gasified totally in rotary kiln without requiring material, only need control material and burn at fire grate tail end just passable." rotary kiln+dual firing chamber " burning process is for ensureing that material often can just provide enough combustion airs at kiln tail in rotary kiln, flue-gas temperature >=1100 DEG C in rotary kiln, arrive rotary kiln afterbody due to equipment and sealing problem has been installed, cold air in air enters kiln tail, contacting with high-temperature flue gas and reduce kiln exit gas temperature on the contrary, just easily there is coking phenomenon in lime-ash.After fire grate is set, control the supply of First air and fire grate wind, control the combustion share of rotary kiln and fire grate well, ensure that flue gas controls at about 950 DEG C at rotary kiln temperature, at this temperature there is not coking phenomenon in lime-ash substantially, also ensure that dual firing chamber has enough fuel gas to make flue gas continue to burn, flue-gas temperature controls more than 1100 DEG C, without the need to adding auxiliary fuel.
The beneficial effects of the utility model: it is rationally distributed, compact conformation, simple to operate, safe and reliable, can meet the requirement that continuous effective is run; Residue is moved, fall, roll, contact completely with air, Thorough combustion; The residual clinker ignition loss < 5% pounded; The use of fire grate device, can increase the control measures of Incineration circumstances in rotary kiln, effectively can reduce the generation of hazardous waste coking in rotary kiln, combustion residue is discharged out of the furnace smoothly.Better control the process of material pyrolytic gasification in rotary kiln, ensure that enough imflammable gas burn in dual firing chamber, ensure flue-gas temperature >=1100 DEG C in dual firing chamber, be conducive to CIU dioxin emission and control.
