Abstract
An incinerator of medical garbage based on gasfying-oxidizing combustion technology is composed of two one-stage incinerators, one two-stage incinerator, an afterheat boiler and other auxiliary units including burners, blower, draught fan, control cabinet and chimney, and features feeding once, synchronous gasification,drying and combustion oxidation, and no secondary pollution.
Description
The present invention relates to a kind of incinerator, particularly a kind of incinerator for medical garbage.
Medical waste is a kind of rubbish with special harm, mainly adopt incinerating method traditional incinerator for medical garbage of taking care of oneself to adopt the mode of continuous feed or intermittent feeding to burn away the refuse basically for a long time, medical waste need be deposited a period of time in burning workshop or feeding warehouse, very easily environment is on every side caused secondary pollution, not only unhygienic but also dangerous.
The purpose of this invention is to provide the novel incinerator for medical garbage that can effectively overcome the problems referred to above generation, it is by gasification-mode of oxidizing burning disposal medical waste, and free from environmental pollution, tail gas need not to handle and gets final product qualified discharge.
The object of the present invention is achieved like this: it comprises two primary reformers, and a secondary reformer and supporting burner, air blast, air-introduced machine, switch board and chimney are formed; Two primary reformer structures are identical, and link to each other with secondary reformer respectively, and one, be provided with valve between the secondary reformer; But the primary reformer top has the upper-turn-type feeding gate, the bottom is provided with the lower turning type skimming door, the uniform ventilating opening of primary reformer cylinder the latter half and tapered segment, and communicate with last lower air duct respectively, its top is provided with thermocouple and negative pressure hole, bottom periphery is provided with three fire holes, the shared air blast of two primary reformers, and each primary reformer windward deferent and lower air duct tube inlet are equipped with butterfly valve; Secondary reformer is a cylinder, horizontal positioned, an end is equipped with burner, the other end is an outlet flue, advance mouth and enter from horizontal side, overfiren air port with advance mouth and converge mutually at secondary reformer.
Use when of the present invention, at first, then it is closed, can effectively avoid medical waste like this second environmental pollution with disposable the packing into of upper-turn-type feeding gate of pending medical waste from the primary reformer top; Valve closing with one, between secondary reformer is lighted secondary reformer then; After about one hour, will prepare the valve open of that primary reformer of burning, and by its base point fire hole igniting; Quantitative air feed behind the primary reformer bottom formation fire bed; The burning fire temperature of primary reformer is more than 800 ℃, and the gasification section temperature is 300～500 ℃, and the drying layer temperature is 100～300 ℃; The furnace temperature of secondary reformer is 900～1100 ℃, and gas residence time is about 1.5 seconds; Burning the back residue is discharged by the lower turning type skimming door of primary reformer bottom.
The present invention is owing to adopt the primary reformer have the upper-turn-type feeding gate to load material, the generation of secondary pollution in the time of therefore can overcoming medical waste effectively and deposit in burning process; Primary reformer burns the tail gas of back generation by secondary reformer high-temperature gasification-oxidizing fire in addition, therefore in the final tail gas institute contain hazardous substance and dust few, it meets atmospheric emission standard (its concrete parameter such as following table) substantially, can directly discharge and can not pollute surrounding environment.

As shown in the figure, the present invention includes 1, one secondary reformer 2 of two primary reformers and supporting burner 4, air blast 5, air-introduced machine 6, switch board 7 and chimney 8 compositions, the volume of each primary reformer 1 of present embodiment is 20M
3, the volume of secondary reformer 2 is 3M
3, its body of heater is double-layer structure: shell and liner, the shell of primary reformer 1 and secondary reformer 2 all adopts A
3Steel is made, and primary reformer 1 liner is a lightweight high alumina casting material, and secondary reformer 2 liners are the phosphate casting material; Two primary reformer 1 structures are identical, and link to each other with secondary reformer 2 respectively, and one, be provided with valve 13 between the secondary reformer 2; But primary reformer 1 top has upper-turn-type feeding gate 22, the bottom is provided with lower turning type skimming door 21, primary reformer 1 cylinder the latter half and the uniform ventilating opening 15 of tapered segment, and communicate with upper and lower air channel 17,20 respectively, also be provided with peephole 18 near the ventilating opening 15, primary reformer 1 top is provided with thermometer hole 16 and negative pressure hole 14, thermocouple is installed in the thermometer hole, bottom periphery is provided with three fire holes 19, two primary reformers, 1 a shared air blast 5, each primary reformer 1 windward deferent 11 and leeward deferent 12 inlets are equipped with butterfly valve 10; Secondary reformer 2 is a cylinder, horizontal positioned, an end is equipped with burner 4 by burner inlet 23, the other end is an outlet flue 24, advance mouth 26 and enter from horizontal side, overfiren air port 25 with advance mouth 26 and converge mutually at secondary reformer 2.In order to make full use of the heat that produces in the medical refuse burning process, be parallel with waste heat hot-water boiler 3 on the flue collector, be separately installed with butterfly valve 9 between the outlet flue 26 of the smoke inlet of waste heat hot-water boiler 6, chimney 8 and secondary reformer 2.
