Technical Field
The utility model belongs to the technical field of medical waste handles, in particular to medical waste full-class heat treatment equipment.
Background
The medical wastes are separated according to the materials, and mainly comprise metal, glass, rubber, fiber, medicine reagents, human tissues and the like. Among them, heat treatment is a common means for disposing of medical waste. For example, Chinese patent documents CN205026690U, CN206989210U and CN 106468441A all adopt a heat treatment mode to dispose medical waste. For the medical waste made of metal and glass, the separation from the medical waste made of other materials is an essential step, or the separation is carried out before the treatment, such as pyrolysis or incineration; or the medical waste is separated after the disinfection is finished, for example, the method for thoroughly treating the medical waste disclosed in the chinese patent document CN 103480636 a includes the steps of immediately sterilizing the medical waste on site, separating the medical waste according to the material by using three-stage vibrating winnowing separation sieves after the medical waste is transported to a factory, connecting a first-stage vibrating winnowing separation sieve in the three-stage vibrating winnowing separation sieves to a fiber collecting device, connecting a second-stage vibrating winnowing separation sieve to a plastic collecting device, connecting a third-stage vibrating winnowing separation sieve to a glass collecting device and a metal collecting device respectively, and recycling according to the material after the separation. Although the treatment mode enables various medical wastes to be recycled to the maximum extent, the treatment cost is high, and the ideal and all-round sterilization effect is difficult to achieve due to the fact that metal and glass are mutually supported and erected.
Disclosure of Invention

The inventive concept created by the invention is as follows: medical waste is classified into two types, incineratable waste and non-incineratable waste. The non-incineratable wastes such as metal, glass and the like are placed in the pyrolysis furnace to finish heat disinfection, the metal and the glass are mutually supported and erected, the mutual gap is large, and the metal and the glass are most suitable for high-temperature disinfection. The pyrolysis furnace is horizontally arranged, the pyrolysis sterilizer is firstly pulled out of the pyrolysis furnace before use, metal and glass are placed in the pyrolysis sterilizer and then pushed into the pyrolysis furnace, the furnace door is closed, and the metal and the glass are transported outside after being sterilized. Other wastes such as bedding and clothing, gauze, cotton swabs, human tissues and household garbage which are used by a patient are all placed in the pyrolysis gasification cavity for incineration treatment, and heat generated by incineration is a first heat supply source of the pyrolysis cavity. The combustion chamber has three functions: the second heat supply source is used as a pyrolysis cavity, and fuel oil is sprayed in a combustion chamber when the hot flue gas generated by burning is insufficient or the temperature does not reach the standard, so that a sufficient heat source is provided for the pyrolysis furnace; secondly, supporting the combustion of the incineratable waste in the pyrolysis gasification cavity; and thirdly, combustible flue gas generated in the pyrolysis gasification cavity is combusted to be converted into heat, so that the burden of the flue gas treatment device is reduced. The cooperation of the pyrolysis gasification cavity, the combustion chamber and the pyrolysis cavity ensures that the treatment process of the medical waste is scientific and efficient, and the general county-level hospital can finish the treatment of all the medical waste in the hospital.
As a modification, the pyrolysis gasification cavity and the pyrolysis cavity are respectively arranged on two sides of the combustion chamber. The combustion chamber provides heat for pyrolysis gasification chamber and pyrolysis chamber simultaneously. When the hot smoke generated by the pyrolysis gasification cavity is enough, fuel oil does not need to be sprayed into the combustion chamber in the treatment process. When the quantity of the articles to be incinerated in the pyrolysis gasification cavity is less and the generated hot smoke is insufficient or the temperature does not reach the standard, the combustion chamber sprays fuel oil, so that a sufficient heat source is provided for the pyrolysis furnace.
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 insufficiently combusted smoke generated by the pyrolysis gasification cavity can be effectively combusted.
As an improvement, the first air supply 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 nozzle can be distributed in the whole combustion chamber, and the combustion is more sufficient.
As a further improvement, the pyrolysis and gasification cavity is provided with a second air supply branch pipe, and the second air supply branch pipe is positioned at the lower part of the pyrolysis and gasification cavity.
As an improvement, ash removal cavities are arranged below the pyrolysis gasification cavities.
As a further improvement, a guide rail for the sliding of the pyrolysis sterilizer is arranged in the pyrolysis furnace.
To sum up, the utility model has the advantages of simple structure, reasonable in design, make ordinary medical site just can accomplish the processing of full type medical waste, the processing is more high-efficient moreover.
