Description

Technical Field

[0001] The utility model relates to the field of sterilization equipment in purification engineering, in particular to a special fresh air sterilization device for purification engineering. Background Art

[0002] Purification engineering refers to controlling the cleanliness, temperature and humidity of the atmosphere that the product is exposed to, so that the product can be produced and manufactured in a good environment. The application fields of purification engineering are very wide, including industrial production, medical and health, biomedicine, laboratories and other fields. In these fields, purification engineering ensures the cleanliness of production, research or medical environment by removing or reducing pollutants in air, water and the surface of objects, thereby ensuring the quality and safety of products and the health of patients. The basic principle of purification engineering is to purify air, water and the surface of objects through a series of physical, chemical and biological methods such as filtration, adsorption, sedimentation, oxidation, etc. Among them, air filtration technology is one of the most important key technologies in purification engineering. Commonly used filters include high-efficiency filters and filters. In addition, positive and negative pressure control technology, temperature and humidity control technology, electrostatic control technology, cleaning and disinfection technology, process control and monitoring technology, and building materials and equipment selection are all indispensable key technologies or aspects in purification engineering. In existing purification engineering, a fresh air sterilization device is usually set up.

[0003] In the existing fresh air sterilization device, it generally includes a sterilization box, a fan, an air inlet pipe and an air outlet pipe. The air inlet pipe is generally arranged on one side of the sterilization box, and the fan is arranged inside the sterilization box. The external air is extracted by the fan. A first filter is usually arranged between the air inlet pipe and the fan to perform preliminary filtration on the extracted air. A sterilization module is arranged on the side of the fan relative to the first filter, which is mainly used for the sterilization effect. The sterilization module is a photohydrogen ion sterilization module, and the air after passing through the sterilization module will eventually be discharged from the air outlet pipe to complete the sterilization process. However, in the existing process of air entering from the air inlet pipe, the existing air inlet pipe is generally set to a columnar shape, and its pipe diameter is set to a fixed shape, so that in the process of extracting air, the air flow speed is fixed. If the air intake is slow or even long-term, it may cause dust accumulation or damage to the internal components of the fresh air sterilization device, thereby affecting its overall performance, which will not only reduce the filtering and sterilization effects of the device, but also affect the service life of the overall device.

[0004] Therefore, it is necessary to provide a new fresh air sterilization device dedicated to purification engineering to solve the above technical problems. Utility Model Content
