Problems solved by technology

[0005] Such a filter element can only block, isolate, and absorb harmful substances in the air. However, the harmful substances filtered from the air still remain on the filter element, which not only cannot cure indoor air pollution but also easily causes secondary pollution.

Abstract

The invention discloses a graphene biological compound enzyme virus removal filter element and a preparation method of the filter element. The filter element comprises an active carbon filter layer, and a coarse filter screen and further comprises an HEPA (high efficiency particulate air) filter screen, a graphene biological compound enzyme solution and an adhesive. The invention further providesthe preparation method of the graphene biological compound enzyme virus removal filter element. The method comprises the steps of preparing a graphene biological compound enzyme solution, adding the adhesive into the graphene biological compound enzyme solution to prepare coating slurry containing graphene and a bio-enzyme, coating the HEPA filter screen with the graphene biological compound enzyme coating slurry, and compounding the graphene biological compound enzyme HEPA filter screen, the coarse filter screen and active carbon to prepare the filter element. According to the graphene biological compound enzyme virus removal filter element and the preparation method, the graphene biological compound enzyme is added into the filter element to prepare the purification filter element with excellent antibacterial and virus killing effects.

Description

technical field [0001] The invention relates to a purification filter element and a preparation method thereof, in particular to a graphene biological compound enzyme virus removal filter element and a preparation method thereof. Background technique [0002] Filter element is a professional term for filtration and purification function. In order to purify the resources of the original fluid and separate the resources easily, the filter element is mainly used in oil filtration, air filtration, water filtration and other filtration industries. [0003] The filter element separates solid particles in liquid or gas, or fully contacts different material components to speed up the reaction time, which can protect the normal operation of the equipment or the cleanliness of the air. When the fluid enters the filter element with a certain specification filter, its impurities are blocked. , while clean fluid exits through the filter element. The liquid filter element makes the liqui...
