Organic hazardous waste harmless treatment device and method

Abstract

The invention relates to an organic hazardous wasteharmless treatment device, which comprises a crushing device for crushing medical solid waste, a reaction kettle for performing hydrothermal carbonization reaction and pyrolytic reaction on the crushed medical solid waste, a liquid storage tank for storing a metal salt solution for the hydrothermal carbonization reaction, and a gas purification device for purifying reaction waste gas, wherein the reaction kettle is used for sequentially carrying out hydrothermal carbonization reaction and pyrolytic reaction on the crushed medical solid waste to generate a carbon material, and the carbon material is used for purifying the reaction waste gas in the gas purification device. According to the invention, medical solid waste is treated in a microwave hydrothermal carbonization and pyrolysis mode, so that thorough disinfection and sterilization of the medical solid waste are achieved; and digestion, hydrothermal carbonization and pyrolysis are integrated in the same equipment, so that no contact with the outside in the whole process is realized, and the treatment process is greatly simplified while the safety of the treatment process is ensured.

Description

technical field [0001] The invention belongs to the field of medical solid waste treatment, in particular to the field of thermal carbonization treatment of solid waste water. Background technique [0002] Medical waste, also known as medical waste, refers to the polluting waste produced by the hospital in contact with the patient's blood, flesh, etc., such as used cotton balls, gauze, adhesive tape, waste water, disposable medical equipment, post-operative waste products, expired medicines, etc.; medical waste has the characteristics of space pollution, acute infection and latent pollution. Unlike domestic waste, medical waste contains a large number of bacteria, viruses and chemical agents, which are highly infectious, biologically toxic and corrosive , Untreated or incompletely treated medical waste is randomly piled up, which can easily cause water, soil and air pollution, cause direct or indirect harm to the human body, and may also become the source of epidemics; the e...

[0002] Medical waste, also known as medical waste, refers to the polluting waste produced by the hospital in contact with the patient's blood, flesh, etc., such as used cotton balls, gauze, adhesive tape, waste water, disposable medical equipment, post-operative waste products, expired medicines, etc.; medical waste has the characteristics of space pollution, acute infection and latent pollution. Unlike domestic waste, medical waste contains a large number of bacteria, viruses and chemical agents, which are highly infectious, biologically toxic and corrosive , Untreated or incompletely treated medical waste is randomly piled up, which can easily cause water, soil and air pollution, cause direct or indirect harm to the human body, and may also become the source of epidemics; the existing medical waste disinfection The structure of the equipment is simple, the performance is relatively simple, and the disinfection effect is poor. Disinfectant is usually used for disinfection during disinfection. This spray disinfection method has certain limitations and cannot thoroughly disinfect the interior of the waste. In addition, for For further treatment, medical waste is usually collected first, and then transported to a treatment point for centralized treatment. It is very inconvenient to deal with, and bacterial leakage is prone to occur during the transfer process, and it is time-consuming and laborious
