Embodiment Construction

[0034] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0035] like figure 2 and image 3 As shown: the medical waste in the present invention is put into the hopper 10 at the top of the pyrolysis gasification furnace, stirred evenly by the agitator 20, scattered to the bottom of the pyrolysis gasification chamber 11, pyrolyzed and gasified at 600-800°C, and produced The combustible gas enters the condenser 13 through the outlet 23 to remove water vapor and tar, and enters the combustion chamber 12 through the combustion nozzle 22 for combustion at 800-1000 ° C. The high-temperature flue gas after combustion is discharged from the flue gas outlet 25 at the top of the combustion chamber After the tar and water vapor removed in the condenser 13 entered the oil-water separator 15, the separated condensed water was sent to the air-water delivery equipment 21 at the bottom of the pyrolysis gasification ...

Abstract

The invention relates to the devices and method of controling harmful exhaust gas of refuse by pyrolytic vaporization processing technique, uses pyrolytic vaporization to dispose waste device, said thermal dissociation method is that refuse enters the reactor through main pyrolytic stove to take pyrolytic reaction and generate mixture gas, said gas enters the mixture gas retort with the rubbish carbon together, steam generator provides steam to enter the mixture gas retort with the high-heat hot smoke gas together, and the combustion gas generated in the retort enters the main pyrolytic stove and heats the retort in the oven, the clean waste gas generated by burning is discharged out of the oven. The application of controlling chloridate vaporization in the invention is based on root, which means preventing the vaporization of the chloridate during the handling process to avoid the occurrence in theory, therefore, could abbreviate the complicated exhaust gas handling largely and no need to handle the secondary substance for exhaust gas handling again, which is just the superiority of the invention.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a device and a method for suppressing harmful substances in garbage tail gas by using pyrolysis and gasification treatment technology. Background technique [0002] From the perspective of environmental protection and resource recycling, the ideal treatment method for solid waste with calorific value is to adopt comprehensive treatment technology. Composting technology eliminates waste through the action of microorganisms, but it has strict requirements on the composition of waste, and it is difficult to treat non-food chain components; solid waste with high calorific value can be treated by incineration technology, but the treatment of incineration tail gas The equipment is huge, the operation technology is complex and the resource consumption is large. The use of pyrolysis gasification technology is an ideal treatmen...
