Description

Exhaust hood for waste gas after high-temperature sterilization of medical waste

Technical Field

The utility model relates to a waste gas treatment technical field specifically is a cover is induced drafted to medical waste material high temperature sterilization back waste gas.

Background

The medical waste is pushed into a sterilization chamber by a container, a cabin door of the sterilization chamber is closed, high-temperature steam is introduced to sterilize the medical waste, the cabin door is opened after the steam treatment is finished, and then the material is crushed, destroyed or compressed. The advantages of the process form compared with the process form of crushing and then steam treatment are as follows: the medical waste after the high-temperature steam treatment meets the high-degree sanitary standard, the operation risk of a subsequent crushing section can be reduced, if bacteria-carrying dust cannot be generated in the crushing process, the problem that workers are infected and pathogenic due to germs remaining in the crushing equipment during the overhaul of the crushing equipment does not exist, and the crushing equipment does not need extra chemical disinfection measures usually.

But some waste gas is generated in the crushing process after the medical waste is treated and sterilized at high temperature. The bacteria can be completely carried and retained by the treatment of the tail gas system, and the retention rate reaches 99.99 percent. However, the waste gas after high-temperature sterilization has high water content and high specific gravity, so that the phenomenon of incomplete absorption exists, and meanwhile, the water vapor in the tail gas is condensed and stays in the air pipe due to the high water content of the tail gas, and when the water amount is large, the water vapor is dropped out through the pipe seams. Therefore, the exhaust hood for waste gas treatment after high-temperature sterilization is improved, tail gas is better absorbed, and a large amount of condensed water in the tail gas is collected and treated.

Thereby preventing the CN filter from clogging while filtering the liquid.

Compared with the prior art, the beneficial effects of the utility model are that: through in two exhaust fans increase again in the middle of the fan housing can absorb tail gas entering tuber pipe better, also can block the comdenstion water simultaneously and fall from this place, after tail gas through behind the exhaust fan gets into the tuber pipe simultaneously, touch behind the condensation stick, behind a large amount of vapor condensation, in the water catch bowl drips along the condensation stick, the water catch bowl rear end is connected with the drain pipe, can be with the water drainage of most condensation in the blind ditch. The utility model discloses can reform transform exhaust-gas treatment's the cover that induced drafts behind the high temperature sterilization, better absorption tail gas collects the processing with a large amount of comdenstion water in the tail gas simultaneously.
