Abstract
Description
Technical Field
[0001] This utility model relates to the field of formaldehyde application technology, specifically a purification structure. Background Technology
[0002] Traditional medical device sterilization is mainly achieved through steam sterilizers. Steam sterilizers use high-temperature, high-pressure steam to kill bacteria and viruses on medical devices, thus ensuring the safety of their use and preventing patients from contracting bacteria or viruses during use. However, with the continuous emergence of new medical devices, sterilization at high temperatures can easily affect the performance and lifespan of some devices. Therefore, low-temperature steam formaldehyde sterilization equipment has been vigorously promoted and developed.
[0003] Formaldehyde has a highly effective sterilization effect on various microorganisms, including vegetative bacteria, spores, mycobacteria, fungi, and viruses. Its sterilization mechanism involves formaldehyde acting as an alkylating agent, which denatures the active genes of bacterial proteins, enzymes, and nucleic acids through alkylation. It can also react with amino, hydrogen sulfide, hydroxyl, and carboxyl groups on protein molecules to form methylene derivatives, thereby destroying bacterial proteins (especially enzymes) and leading to microbial death. However, some existing low-temperature formaldehyde sterilizers have shortcomings. For example, they typically directly release the formaldehyde-containing gas mixture or collect it for later treatment. These existing methods pose certain safety hazards, and the collection and reprocessing are time-consuming. Utility Model Content
[0004] The present invention provides a purification structure that addresses the safety hazards and time-consuming nature of existing methods for collection and reprocessing.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A purification structure includes a first purification chamber and a second purification chamber. The first purification chamber has a connection port for communicating with a vacuum pump, and the second purification chamber has an exhaust port. The first and second purification chambers are connected. Both the first and second purification chambers can treat formaldehyde to a certain extent, thereby reducing the formaldehyde content in the mixed gas. In use, the mixed gas enters the first purification chamber through the connection port for purification, then enters the second purification chamber for further purification, and finally exits through the exhaust port. This structure significantly reduces the formaldehyde content in the mixed gas through two purification processes, directly eliminating potential safety hazards, and is simple and practical.
[0007] Furthermore, both the first and second cleanrooms are equipped with an oxidation catalyst, a cleanroom heating assembly, and a cleanroom temperature sensor. In use, the cleanroom heating assembly heats both the first and second cleanrooms, allowing the formaldehyde in the mixed gas to react more effectively with the oxidation catalyst. Simultaneously, the cleanroom temperature sensor detects the indoor temperature.
[0008] Furthermore, it includes an exhaust fan, which is connected to the exhaust port. This structure, when used in conjunction with the formaldehyde purification structure, allows for better exhaust of the mixed gas.
[0009] Furthermore, a pipe insulation connector is installed on the connection port. This structure prevents the pipes connected to the connection port from being damaged by the high temperatures of the first and second cleanrooms.
[0010] Beneficial effects: During use, the mixed gas enters the first purification chamber through the connecting port for purification, then enters the second purification chamber for purification, and finally exits through the exhaust port. This structure, through two purification processes, significantly reduces the formaldehyde content in the mixed gas, directly eliminating and reducing safety hazards. Furthermore, the structure is simple and practical. Attached Figure Description

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0016] like Figure 1 , Figure 2As shown, this embodiment of a purification structure includes a first purification chamber 1 and a second purification chamber 2. The first purification chamber 1 has a connection port 3 connected to a vacuum pump, and the second purification chamber 2 has an exhaust port 4. The first purification chamber 1 and the second purification chamber 2 are connected. An oxidation catalyst 5, a purification chamber heating component 6, and a purification chamber temperature sensor 7 are installed in both the first purification chamber 1 and the second purification chamber 2. An exhaust fan is included, and the exhaust fan is connected to the exhaust port 4. A pipe heat-insulated connector 8 is installed on the connection port 3. In use, the mixed gas enters the first purification chamber 1 through the connection port 3 for purification, then enters the second purification chamber for purification, and finally exits through the exhaust port 4. Using this structure, the formaldehyde content in the mixed gas can be greatly reduced through two purification processes, directly eliminating and reducing safety hazards. The structure is simple and practical.
