Embodiment 1

[0036] Further explanation in conjunction with accompanying drawings: figure 1 It is a structural diagram of the internal view of the medical waste classification treatment device of this embodiment, including a mixing chamber, a high-pressure hydrolysis unit, a sewage treatment unit and a mixing treatment unit.

[0037] like figure 1 As shown, the mixing chamber includes a mixing chamber inlet 101, a stirring shaft 102, a stirring blade 103, a stirring motor 104, a mixing chamber water inlet 105 and a mixing chamber outlet 106; The feed port is arranged on the top wall of the mixing chamber for discharging medical waste into the mixing chamber, the stirring shaft is vertically arranged in the mixing chamber, the stirring blades are evenly distributed on the stirring shaft, and the stirring motor It is arranged outside the mixing chamber and connected with the stirring shaft through a coupling to drive the rotation of the stirring shaft. The water inlet of the mixing chamber ...

Embodiment 2

[0046] A method for graded treatment of medical waste, which is carried out using the device for graded treatment of medical waste in Example 1, specifically comprising the following steps:

[0047] 1) Put the medical waste into the mixing chamber through the material inlet of the mixing chamber, and at the same time open the water inlet of the mixing chamber to discharge tap water, start the stirring motor, and open the outlet of the mixing chamber after 5 minutes to discharge the materials.

[0048] 2) Put the material discharged from the discharge port of the mixing chamber into the high-pressure tank through the feed port of the high-pressure tank. When the material in the high-pressure tank reaches 10% of the total volume, open the horizontal inlet pipe and start the booster pump for the high-pressure tank, adjust the air temperature in the gas heating chamber to 115°C, and open the exhaust port of the high-pressure tank at the same time.

[0049] 3) When the material in ...

Abstract

The invention relates to a medical waste staged treatment device and method. The medical waste staged treatment device comprises a mixing chamber, a high-pressure hydrolysis component, a sewage treatment component and a mixed material treatment component. Through the specific settings of all the components, the staged treatment method comprises the following steps of: performing high-pressure andhigh-temperature steam treatment on materials added with water for hydrolyzing medical waste, thereby completely killing harmful microorganisms in the medical waste and meanwhile hydrolyzing and breaking organic matters in the medical waste into high-quality organic matters, then performing air bubble treatment, filtration, flocculation, adsorption and other steps on the water body having specificcomponents, realizing the screening of solid matters by a specific screening method of the solid matters, and thus, the subsequent treatment is facilitated.

Description

technical field [0001] The invention relates to the field of medical waste treatment, in particular to a medical waste classification treatment device and treatment method. Background technique [0002] Due to its complex composition, medical waste not only contains various conventional wastes such as fabrics, glass, plastics, and metals, but also contains toxic and harmful liquids, heavy metal elements, blood, human tissues, and harmful microorganisms. At present, the treatment of medical waste is mainly incineration, and there is still landfill in a small number of areas. However, the incineration process will not only cause secondary pollution of the gas, but also cause unnecessary waste of a large amount of useful materials. At present, there are also some other recycling methods, mainly through the disinfection process to kill harmful microorganisms, and then through classified recycling and subsequent treatment. However, this treatment process not only consumes a lar...
