Abstract
The incinerator, the gasifying pyrolysis stove as well as the dust removal and fume extractor are utilized in the invented equipment. The incinerator, the pyrolysis gasifying stove and the collector for cracked gas are integrated as whole body. The furnace body of the gasifying pyrolysis oven is divided into a stove chamber and a cracking chamber. The exit of the chain on the bottom of the cracking chamber is connected to the incinerator through a channel. Cracked coke can pass through two windshields in the channel, but fume and frame produced in the incinerator cannot enter into the stove. Thus, gasifying pyrolysis effect is happened in the stove without burning on. Garbage is decomposed into cracked coke, which will be burning in the incinerator, and cracked gas, which will be filtered out. The beneficial effect is that if burning these gases, dioxin will be produced. The combustible gas generated in the stove is as the fuel for the incinerator.
Description
Technical field
The invention belongs to garbage incineration equipment.
Background technology
In recent years along with environmental protection requirement, the development of garbage combustion device and production have been subjected to the great attention of domestic and international many scientific research institutions and enterprise, it burns effect, purification efficiency, automaticity etc. and all is greatly increased, as rotary burning disposal complete set of equipments, self-burning type incinerator etc.The operation principle of incinerator is roughly at present: rubbish drops into Burning Room by feeding mouth, sends into air and auxiliary high-grade fuel simultaneously.Organic substance generation vigorous oxidation heat release burning in the rubbish is being arranged under the condition of abundant oxygen.The characteristics of this class incinerator are that drying, pyrolysis, gasification and the combustion process of rubbish all finished in same reactor.Aspect the processing of tail gas and slag: the gas after the producer that has is designed to burn through a cyclone dust collectors dedusting after directly the discharging, slag discharges automatically by slag notch; Gas after also having some producers to be designed to burn with burn once more after the secondary wind that blasts (generally being cold air) mixes, and after discharge after the cyclone dust collectors dedusting.But for medical waste, the combustible component in the rubbish all is an organic matter basically, and contains a large amount of carbon, hydrogen, oxygen, nitrogen, sulphur, phosphorus and halogen etc., therefore removes in combustion process and can produce CO
2, outside the steam, also will be with hydrogen halide, SOx, NOx etc.This shows that the smoke components during the medical waste burning has certain difference with the flue gas composition that general fuel combustion is produced, and shows that mainly the concentration ratio of S, HCl and O is higher.And S, Cl and O and other composition will produce the extremely toxic substance dioxin at a certain temperature, and in a single day well-known dioxin produces and will be difficult to remove.Present burning process is not if adopt new method, even tail gas has been done purified treatment, the emission problem of dioxin extremely toxic substance can not obtain basic solution so, and this type of burning process needs extraneous fuel supply in addition, and operating cost is also higher.
Summary of the invention
The purpose of this invention is to provide a kind of novel medical waste pyrolyzing, gasifying and incinerating device that can effectively stop the discharging of dioxin extremely toxic substance and save operating cost.
Concrete structure of the present invention as shown in Figure 1, 2.Medical waste pyrolyzing, gasifying and incinerating device has: incinerator (1), pyrolysis gasification furnace (2), dedusting fume extractor (3), heat hot water system (4) etc.The main distinction of the present invention and traditional burning method is: the pyrolyzing, gasifying and incinerating method has adopted two type of furnaces: pyrolysis gasification furnace and incinerator, finish drying, pyrolysis and the high temperature incineration process of rubbish respectively.Being about to incinerator (1) and pyrolysis gasification furnace (2) and cracking gas gatherer (5) organically is connected as a single entity.Rubbish carries out drying, pyrolytic and gasification in pyrolysis gasification furnace, and is broken down into cracking Jiao and cracking gas.The body of heater of pyrolysis gasification furnace (2) is divided into burner hearth (6) and cracking room (7), is provided with adjustable plate (8) and feeding gate (9) between burner hearth (6) and cracking room (7), and having on the adjustable plate (8) can rotating blades.The top of pyrolysis gasification furnace (2) is provided with charging aperture (10) and cracking gas outlet (11).Cracking room (7) bottom is provided with the chain (12) that can rotate, the chain outlet is provided with a passage (13) and communicates with incinerator (1), passage (13) lining is provided with twice deep bead (14) makes cracking Jiao can enter incinerator (1), and flue gas and flame can not enter pyrolysis gasification furnace (2) in the incinerator, thereby guarantee that pyrolysis gasification furnace is the pyrolytic gasification effect that only takes place under anoxia condition, and do not burn.Combustion chamber (15) is arranged between incinerator (1) and the pyrolysis gasification furnace (2).Medical waste enters pyrolysis gasification furnace from charging aperture (10), rubbish in the burner hearth enters the chain (12) of cracking room bottom by feeding gate (9) and adjustable plate (8), under the heat effect of combustion chamber (15), the garbage decomposition that is distributed on the chain is become cracking Jiao and cracking gas.Cracking Jiao after the cracking delivers to boiling burning in the incinerator (1) by chain (12) via twice deep bead (14), reaches the effect of abundant burning.The product of cracking Jiao after boiling is burned has lime-ash and flue gas in the incinerator, and lime-ash is discharged through self-skimming.Flue gas enters combustion chamber (15) by gas approach (28) and carries out second-time burning.The cracking gas that produces in the pyrolysis gasification furnace contains combustible gas component, as: CO, H
2, CH, HS compound etc., but HCl is also arranged, SO
2Sour gas, water and lime-ash etc., sour gas not only can etching systems, and also are the main sources that produces dioxin.Cracking gas gatherer (5) is made up of heat exchanger (16), filtering tank (17) and air accumulator (18) three parts, and the absorbed layer (21) of filter course (19), drainage layer (20) and absorption sour gas is set in the filtering tank (17).Cracking gas is behind the gas collection of pyrolysis gasification furnace top, enter heat exchanger (16) and cold air heat exchange, then through gas filtration, process such as deacidify, dewater, remove pernicious gas, fuel gas is sent to air accumulator (18) through the booster fan (22) of setting between filter tank (17) and the air accumulator (18).Incinerator (1) is provided with water-cooling wall (23) with the furnace wall of pyrolysis gasification furnace (2), and the flue (24) between pyrolysis gasification furnace (2) and the water-cooling wall (23) constitutes the dry kiln (25) of burner hearth (6).Combustion chamber (15) is provided with fuel nozzle (26), secondary wind air intlet (27) and from the gas approach (28) of incinerator (1).
Beneficial effect of the present invention and advantage are: removed pernicious gas 1., in pyrolysis gasification furnace, the pernicious gas gasification is separated, remove without burning directly to cause outside the stove, these pernicious gases are the main sources that produce dioxin, significantly reduce the source and the generation condition that produce dioxin like this.2. the combustible gas that gasification produces in the pyrolysis gasification furnace will be as the fuel of incinerator, when igniting with a small amount of extraneous fuel, behind the incinerator for thermal decomposition steady operation, to replace extraneous fuel with cracking gas, and also have rich tolerance to use for extraneous, therefore, compare, saved the spending of fuel cost greatly with traditional incinerating method.
