Description
The present invention is to be that on 02 10th, 2012, application number are 201210029448.7, invention and created name is divided an application for " closed incinerator " original application day.
Technical field
The present invention relates to the incinerator technical field, particularly a kind of closed incinerator.
Background technology
Discarded rubbish comprises: town pavement sweeping rubbish, domestic garbage, food garbage, medical waste, processing of farm products discarded object, organic sludge, ight soil, waste or used plastics and tire etc. are referred to as discarded rubbish.The conventional garbage processing mode generally takes landfill or landfill to reclaim marsh gas power generation and direct burning electricity generation; These methods only are to have utilized few partial heat energy of rubbish; But fume emission is always arranged in the burning electricity generation process; Cause the secondary pollution problem still to fail to solve, for example: the secondary pollution that the penetrating fluid of garbage loading embeading pollutes and flue gas of refuse burning discharges etc.
At present, the incinerator that is used for discarded garbage disposal mainly contains mechanical kiln grate furnace, fluidized bed incinerator, swinging incinerator, static pyrogenation incinerator etc.Mechanical kiln grate furnace the most commonly used generally is divided into three phases, i.e. dryer section, burning zone and burning segment.Fluid bed is mainly by keeping coal body flow air dispersal device, incombustible discharger, incombustible screening coal body EGR etc. to form.The revolution cellar for storing things is the cylinder interior at steel; Install refractory liner additional and porose steel plate is welded into tubular; With the rubbish direction of transfer is the axle center, is the equipment of small angle inclination rotation, is with two groups of ring-type steel wheel rims and several roller outside it and supports; Cylinder is rotated slowly, and rubbish is stirred and is fed forward.The common trait of these stoves is: (1), ignition temperature are in 800-900 ℃ of scope, and ignition temperature is low, and combustion efficiency is poor, is easy to generate pernicious gases such as dioxin; (2), combustion process is wanted heavenwards to discharge a large amount of flue gases (like nitrogen oxide, carbon dioxide, sulfur dioxide and unburnt pernicious gas dioxin etc.) and is caused secondary pollution; (3), combustion process need add auxiliary fuel (like coal, wet goods) and cause the burning cost up, consumes a large amount of energy, causes the wasting of resources; (4), the combustion adjuvant that uses of combustion process is air because nitrogen is not participate in combustion reaction and absorb great amount of heat again in the air, the heat waste consumption is big, the thermal efficiency is low thereby cause.This shows that there is following weak point in these stoves: furnace binding is complicated, combustion space is big, the bubbling air amount is big, smoke discharge amount is big, ignition temperature is low, dust is many, the heat waste consumption is big, neither energy-conservation also not environmental protection.
Flue gas pollutant all is to atmosphere through smoke stack emission in existing incinerator.Owing to reason such as flue gas treatment operating costs height or treatment system be difficult in maintenance; Cause a large amount of flue gases to contain poisonous pernicious gas (as: sulfur dioxide, carbon monoxide, nitrogen oxide, dioxin etc.) and fly ash emission; Surrounding air, water source and soil are caused severe contamination, and the discharging for a long time of these flue gases can seriously jeopardize existent environment of people.Still unresolved in the existing incinerator to flue gas secondary pollution problem.
Owing to there is a large amount of flue gases constantly to discharge, the heat of waste incineration can be pulled away a part of heat along with fume emission descends furnace temperature in the existing incinerator; And because rubbish contains the moisture height and calorific value is low, be difficult to burning, dry these rubbish need consume a large amount of hot-airs, and the heat that waste incineration produces also causes furnace temperature decline because of adding the hot-air part that is depleted again; In addition, because the furnace volume of incinerator is big, the surface of burner hearth area of dissipation is big, radiating rate is fast and heat dissipation capacity is big, and the heat that waste incineration produces constantly dispels the heat and the part that is depleted along with surface of burner hearth, and furnace temperature is descended.Consequently existing various waste incineration furnace thermal efficiencies are low, can not reach energy-saving and cost-reducing effect.
The combustion adjuvant of combustion oxidation reaction all is to adopt airborne oxygen in existing incinerator; Because the composition of rubbish is comparatively complicated; The calorific value unstability causes furnace temperature unstable; Calorific value generally can add exotic fuels such as diesel oil or coal when low and keep furnace temperature, that is to say to consume the furnace temperature that the part energy can be stablized incinerator.Having under the oxidant condition, the plastics in the rubbish burn when insufficient, cause the generation of toxic and harmfuls such as dioxin easily and cause serious pollution.Waste incineration need strengthen air capacity usually to increase turbulivity, lets air and rubbish in burner hearth, form fluidized state, can cause like this that the flying dust amount increases in the flue gas, the gas cleaning intractability is increased and causes the processing cost increase.Effectively do not solved yet improving pollutants controls such as furnace temperature, minimizing energy use amount and flue gas and dust in the existing incinerator.
