Medical waste innocent treatment equipment

Technical Field

The utility model belongs to the technical field of medical waste handles, in particular to medical waste innocent treatment equipment.

Background

The medical waste mainly comprises expired biochemical drugs or medical consumables which possibly contain a large amount of bacteria and viruses, and is extremely infectious and extremely easy to pollute the environment. In the prior art, the main treatment mode of medical waste is incineration treatment. The incineration treatment is a chemical process of deep oxidation, under the action of high-temperature flame, medical waste in the incineration equipment is converted into residue and gas through three stages of drying, ignition and incineration, and the infection source and harmful substances in the medical waste can be effectively destroyed in the incineration process. For example, chinese patent document CN 105333443 a discloses a harmless treatment apparatus for medical waste, which treats medical waste by incineration. And a high-temperature carbonization pyrolysis mode is adopted for treatment, such as a medical waste high-temperature carbonization pyrolysis high-temperature gasification incineration low-dioxin discharge system and a method disclosed in Chinese patent document CN 106468441A. However, a large amount of dense smoke is generated by single incineration treatment, the subsequent tail gas treatment capacity is large, and the smoke is toxic and harmful; and the single pyrolysis carbonization treatment is relatively thorough, but the energy consumption is high.

Disclosure of Invention

An object of the utility model is to overcome prior art's not enough, provide a medical waste innocent treatment equipment, combine together pyrolysis carbonization technology and incineration process, make medical waste can classification to it is more high-efficient to make the processing procedure.

In order to achieve the above purpose, the technical solution of the present invention is as follows:

medical waste innocent treatment equipment, including burning chamber, combustion chamber, flue gas processing apparatus, the combustion chamber still includes the pyrolysis chamber for burning the required heat energy of chamber provides burning, pyrolysis chamber and combustion chamber intercommunication, are provided with the pyrolysis oven in the pyrolysis chamber, and the pyrolysis oven sets pyrolysis gas processing apparatus.

The inventive concept created by the invention is as follows: the medical wastes are respectively treated according to the properties, articles polluted by blood, body fluid and excrement of a patient comprise cotton balls, cotton swabs, drainage cotton slivers, gauze, bedding and clothes and the like, and domestic wastes generated by the patient are placed in an incineration chamber for incineration treatment, and the generation amount of the wastes is very large. The culture medium of discarded antibiotics, medicines, chemical disinfectants and pathogens, plastic products and the like are pyrolyzed in the pyrolyzing furnace, the production amount of the wastes is not small, the relative water content is large, and dense smoke and toxic gas are easily produced if the wastes are directly burnt. After the two wastes are separately treated, the heat generated by the incineration cavity can partially support the heat required by pyrolysis and carbonization, no toxic gas is generated by high-temperature pyrolysis and carbonization, and the pyrolysis gas generated by high-temperature pyrolysis and carbonization also returns to support combustion, so that the treatment engineering is more scientific and efficient.

As a modification, the incineration chamber and the pyrolysis chamber are respectively arranged on two sides of the combustion chamber. The combustion chamber provides heat for the incineration chamber and the pyrolysis chamber simultaneously.

As the improvement, be provided with first air supply branch pipe in the combustion chamber, the inner wall of combustion chamber is provided with the fuel sprayer, and the fuel sprayer passes through defeated oil pipe and oil pump connection. The oil mist sprayed by the oil spray nozzle and the wind power of the first air supply branch pipe form a curtain layer, so that the oil mist can be fully combusted, and the incomplete combustion powder generated by the incineration cavity can be effectively combusted.

As an improvement, the first air supply branch pipe is provided with a plurality of groups of air outlet holes from bottom to top, so that the oil mist sprayed by the oil spray nozzle can be distributed in the whole combustion chamber, and the combustion is more sufficient.

As the improvement, the incineration chamber is provided with a second air supply branch pipe, and the second air supply branch pipe is positioned at the bottom of the incineration chamber. The second air supply branch pipe supplies air to the incineration chamber.

As an improvement, ash cleaning cavities are arranged below the incineration cavity and the pyrolysis cavity.

As an improvement, the pyrolysis gas treatment device is a cyclone dust collector provided with a spraying device.

To sum up, the utility model discloses combine together pyrolysis carbonization technology and incineration process, with medical waste classification, make the course of treatment more high-efficient.
