Embodiment Construction

[0024] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0025] The medical waste pyrolysis treatment device of the present invention comprises a pyrolysis furnace 1, ancillary equipment 2, and an induced draft fan 3, and the three parts are connected through pipelines. The furnace body is equipped with a feeding device 4 on the top of the furnace body. The feeding device 4 is a double-layer feeding port, which is divided into an upper layer feeding port a and a lower layer feeding port b. A flue gas channel 5 is arranged around the furnace body, and the flue gas The passages 5 communicate with each other at the upper part of the furnace body, and are arranged at intervals in the middle of the furnace body. The first heating wires 13 are arranged between the flues, and the flues 5 at the bottom of the pyrolysis furnace 1 communicate with each other. A pyrolysis gas pipeline 6 is arranged on the side of the furnace body, and...

Abstract

The invention discloses a pyrolysis-gas-recyclable medical waste pyrolysis treatment device which comprises a pyrolysis furnace, accessory equipment and an induced draft fan. The pyrolysis furnace comprises a furnace body, a feed device, a flue gas passage, a pyrolysis gas pipeline, an ash discharging gear and temperature measurement and control systems, and each temperature measurement and control system mainly comprises a temperature sensor, a temperature display instrument and an automatic controller. The accessory equipment comprises a half-dry type scrubber and a bag type dust collector. By reasonable design of the furnace body structure, automatic measurement and control of the furnace hearth temperature is realized, generated pyrolysis gas enters the furnace bottom to be combusted through the pipeline designed specially, and efficiency of the pyrolysis furnace is improved; meanwhile, the problem of inherent tar in pyrolysis equipment is solved, flue gas generated by combustion of the pyrolysis gas is purified prior to being discharged, and harmlessness, reduction and stabilization of treatment of medical waste are realized. In-situ treatment of the medical waste is realized, and secondary pollution caused by transportation is also avoided.

Description

technical field [0001] The invention belongs to the technical field of high-temperature pyrolysis treatment of solid combustible waste, and specifically relates to a small-sized high-efficiency medical waste pyrolysis treatment device which uses electric heating as an auxiliary driving heat source and generated pyrolysis gas as a main heat source. Background technique [0002] As special waste, medical waste is generally defined as directly or indirectly infectious, toxic and other hazardous waste produced by medical institutions in medical treatment, prevention, health care and other related activities. It is mainly derived from medical supplies such as surgery, laboratory tests, and disposable injections. It often contains a variety of infectious pathogens. A large amount of organic matter is extremely perishable, breeding mosquitoes and flies, and easily causing disease transmission. It has full-space pollution, acute infection, and latent Pollution and other characterist...
