Description

Technical Field

[0001] The utility model belongs to the technical field of tail gas purification, and particularly relates to a tail gas purification and treatment mechanism for medical waste incineration. Background Technique

[0002] Medical waste refers to waste generated by medical and health institutions in medical treatment, prevention, health care and other related activities, which has direct or indirect infectivity, toxicity and other hazards.

[0003] During the incineration of traditional medical waste, a large amount of toxic flue gas is often generated. Therefore, it is often necessary to filter and purify the discharged flue gas through a flue gas purification device. However, the flue gas generated during the incineration of medical waste often has a high temperature. When these high-temperature flue gases pass through the filtration and purification, it is easy to cause thermal corrosion to the filter layer inside the flue gas purification device. Over time, it will affect the filtration effect and service life of the filter layer. Therefore, a tail gas purification and treatment mechanism for medical waste incineration is needed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tail gas purification and treatment mechanism for medical waste incineration to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A tail gas purification and treatment mechanism for medical waste incineration, including a bottom plate, on which an incinerator is fixedly arranged. A smoke exhaust pipe is connected to the incinerator. One end of the smoke exhaust pipe is connected to a preliminary filtration frame. A heat-resistant filtration layer is arranged inside the preliminary filtration frame. The preliminary filtration frame is fixedly connected to the bottom plate. The upper surface of the preliminary filtration frame is fixedly connected to a cooling ring frame through a plurality of support rods. A section of the smoke exhaust pipe passes through the inside of the cooling ring frame. A plurality of heat conduction fins are fixedly connected to the inner surface of the cooling ring frame. Each heat conduction fin hermetically penetrates the outer surface of the smoke exhaust pipe and extends into the inside of the smoke exhaust pipe. A refrigeration body is fixedly connected to the bottom plate. The refrigeration body is communicated with the cooling ring frame through two circulation pipes.

[0006] By setting the cooling ring frame, under the operation of the refrigeration body, the coolant can be circulated and transported to the inside of the cooling ring frame through the circulation pipe. The cooling ring frame will reduce the temperature of the flue gas passing through this section of the smoke exhaust pipe through internal refrigeration and heat conduction of the heat conduction fins. During this period, the extension of the heat conduction fins inside the smoke exhaust pipe can increase the contact area of the flowing flue gas, so that the temperature of the high-temperature flue gas can drop rapidly. In addition, when the flue gas in the smoke exhaust pipe enters the preliminary filtration frame, it can be preliminarily filtered at the heat-resistant filtration layer. At the same time, the heat-resistant filtration layer can also dilute a part of the heat, thereby reducing the high temperature inside the smoke exhaust pipe, which helps to reduce the thermal corrosion effect during subsequent flue gas filtration and extend the service life of the machine.

[0007] As a preferred embodiment, one side of the preliminary filter frame is connected with an adapter pipe.

[0008] As a preferred embodiment, one end of the adapter pipe is connected with a flue gas purification processor frame.

[0009] As a preferred embodiment, a flue gas pump is arranged on the adapter pipe.

[0010] As a preferred embodiment, the flue gas pump is fixedly arranged on one side of the flue gas purification processor frame.

[0011] As a preferred embodiment, a smoke outlet pipe is connected and arranged on one side of the flue gas purification processor frame.

[0012] By arranging the flue gas purification processor, under the operation of the flue gas pump, the flue gas in the preliminary filter frame is extracted through the adapter pipe and sent into the flue gas purification processor frame for filtration and purification. Finally, the purified flue gas will be discharged into the air through the smoke outlet pipe, thereby realizing the treatment of the flue gas from medical waste incineration.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] In the present utility model, by arranging the cooling ring frame, under the operation of the refrigeration body, the coolant can be circulated and transported into the cooling ring frame through the circulation pipe. The cooling ring frame will reduce the temperature of the flue gas passing through this section of the smoke exhaust pipe through internal refrigeration and the heat conduction of the heat conduction fins. During this period, the extension of the heat conduction fins in the smoke exhaust pipe can increase the contact area of the flowing flue gas, so that the temperature of the high-temperature flue gas can drop rapidly. In addition, when the flue gas in the smoke exhaust pipe enters the preliminary filter frame, it can be preliminarily filtered at the heat-resistant filter layer, and at the same time, the heat-resistant filter layer can also dilute a part of the heat, thereby realizing the reduction of the high temperature in the smoke exhaust pipe, which helps to reduce the thermal corrosion effect during subsequent flue gas filtration and extend the service life of the machine body.

[0015] In the present utility model, by arranging the flue gas purification processor, under the operation of the flue gas pump, the flue gas in the preliminary filter frame is extracted through the adapter pipe and sent into the flue gas purification processor frame for filtration and purification. Finally, the purified flue gas will be discharged into the air through the smoke outlet pipe, thereby realizing the treatment of the flue gas from medical waste incineration.
