Electric heating air filtration element and low-energy-consumption high-temperature disinfection and sterilization device for air

Abstract

The invention provides an electric heating air filtration element and a low-energy-consumption high-temperature disinfection and sterilization device for air. The electric heating air filtration element comprises high-temperature-resistant primary filter cotton, a metal aluminum net, an insulating electric heating wire and a high-temperature-resistant efficient air filtration element, wherein themetal aluminum net is mounted at an air inlet of the high-temperature-resistant efficient air filtration element and is attached to an aluminum-foil paper partition plate of the air filtration element; the insulating electric heating wire is fixed on the metal aluminum net, and the primary high-temperature-resistant filter cotton covers the surface of the metal aluminum net; and two ends of the insulating heating wire are connected with a working power supply. The insulating electric heating wire in the electric heating air filtration element can heat the primary filter cotton and the high-temperature-resistant efficient air filtration element at the same time in a power-on stage, and bacteria and viruses attached to the primary filter cotton and the high-temperature-resistant efficient air filtration element are subjected to high-temperature disinfection and sterilization; and the sterilization device achieves low-energy-consumption high-efficiency air sterilization and purification effects through filtering and sterilization control at different time periods.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an electric heating air filter element and a low-energy-consumption air high-temperature sterilization device using the filter element. Background technique [0002] Traditional air purification equipment mostly uses filtration technologies such as activated carbon filters and HEPA (high-efficiency particulate air filters). Virus disinfecting function, or even though it has the active disinfecting function, the killing is not complete due to the dead corners of the pleated filter element, so that when the filter is replaced, the bacteria and viruses attached to the filter will spread again and cause secondary pollution. endanger people's health. [0003] In terms of air disinfection, the commonly used disinfection methods are ultraviolet disinfection, ozone disinfection and so on. Both UV and ozone disinfection require a long air residence time for complete disinfection. In addit...

Problems solved by technology

At present, the air high-temperature antivirus device mainly has two working modes. One is to heat the air flow, such as the scheme disclosed in the publication number CN 2627394A. The power consumption required to instantly heat the airflow temperature to the virus disinfecting temperature is large

In addition, this type of method also needs to consider the cooling problem of the exhausted air at the same time, such as the solution disclosed in the publication number CN107525170A, which solves the cooling problem but increases the complexity of the device; Heating, such as the disclosed scheme of Publication No. CN 109556207A, which utilizes air to take away part of the heat of the filter element through convective heat exchange, but the method leads to a large increase in the power required to maintain the filter element at the virus killing temperature, which lacks practicability
