Embodiment Construction

[0021] Attached below figure 1 The specific embodiment of the present invention is described further:

[0022] The present invention comprises the following steps:

[0023] 1. Classify medical waste as combustible medical waste and non-combustible medical waste;

[0024] 2. Crushing and drying combustible medical waste;

[0025] 3. The combustible medical waste after crushing and drying is filled into the boiler for incineration, and the steam generated by the boiler during the incineration process is transported to the steam accumulator;

[0026] 4. Smash and disinfect non-combustible medical waste.

[0027] The flue gas generated during the incineration process of the combustible medical waste described in step 3 needs to be purified and discharged after reaching the emission standard, so as to avoid secondary pollution of medical waste.

[0028] The steam released by the steam accumulator described in step 3 can also be input into the hospital heating system or other d...

Abstract

The invention discloses a medical waste treatment method with an afterheat recovery heat accumulator. The problem that the environment is polluted because of improper daily medical waste treatment is solved. The method comprises the following steps of: firstly classifying the medical wastes into combustible medical wastes and incombustible medical wastes; pulverizing, drying and burning the combustible medical wastes; performing tail gas purification treatment; pulverizing and sterilizing the incombustible medical wastes; and finally, turning the burned furnace slag and the sterilized medical wastes into harmless trashes. Steam generated by the boiler in the burning process is delivered to a steam heat accumulator; high-temperature steam released by the steam heat accumulator is input to the sterilization step of sterilizing the incombustible medical wastes, and also can be input to a medical heat supply system or sterilizing equipment for heating or sterilizing; the combustible medical wastes are subjected to harm-free treatment and reduction treatment by burning; and the tail gas generated after burning is purified, so that secondary pollution of the medical wastes is avoided.

Description

technical field [0001] The invention relates to a method for treating medical waste, in particular to a method for treating medical waste with a waste heat recovery accumulator. Background technique [0002] At present, medical waste is seriously involved in environmental pollution. Most hospitals in my country generally adopt two methods for the treatment of medical waste. One is to mix medical waste and domestic waste, and the other is to use small incinerators in various hospitals for incineration. Among them, the treatment method of mixing medical waste and domestic waste will cause secondary pollution to the surrounding environment. Incineration is an effective means of harmless and reduction treatment of medical waste, but the exhaust gas treatment equipment of small incinerators in hospitals is not perfect, and the exhaust gas is directly discharged into the atmosphere, causing serious secondary pollution to the environment. If the medical waste is sent to the outdoo...
