Abstract

The invention discloses a filter used for a ventilation system. The filter comprises a filter screen, wherein a ceramic composite material is coated on the filter screen; the ceramic composite material consists of the following ingredients in percentage by weight: 45 to 54 percent of polar mineral tourmaline with the particle size of 0.1 to 1.5 microns, 3 to 9 percent of rare earth nitrate or rare earth oxide and 43 to 52 percent of transition metal oxide. In the filter, the filter screen is coated by adopting the ceramic composition material which can generate negative ions so as to ensure that the air enters a house through the filter screen keeps enough oxygen, enhance air filtering capacity and protect the ventilation system at the same time. A filter material is a metal composition screen material, which has the characteristics of high strength, wind erosion resistance, rust resistance, washability and the like.

Description

technical field [0001] The invention relates to a filter, in particular to a filter for ventilation and exhaust systems. Background technique [0002] Ventilation and exhaust systems are generally used in workshops, factories, laboratories and clean operating rooms with high cleanliness. With the improvement of living standards, people also perform corresponding ventilation and exhaust for the air in the home, such as range fume extraction devices and air conditioners. For the ventilation and exhaust system of air conditioners, which not only supply air to the room but also exhaust it to the outside, it is necessary to filter the passing air. There is a corresponding air filter device on this ventilation system. [0003] At present, the air filter device uses silk mesh as the filter layer, such as filter cloth, which mainly prevents the passage of dust with larger particle sizes in the air. It has the characteristics of large filter area, low resistance, and long service lif...
