Plasma collaborative photocatalytic air sterilizing and purifying device

The invention discloses a plasma collaborative photocatalytic air sterilizing and purifying device. The plasma collaborative photocatalytic air sterilizing and purifying device comprises a case, a fan, a plasma collaborative photocatalyst reacting part and an adsorbing layer, wherein the fan, the plasma collaborative photocatalyst reacting part and the adsorbing layer are mounted into the case from bottom to top in sequence; an air inlet is formed in the lower part of the case, and an air outlet is formed in the upper part of the case; the fan is provided with an air inlet pipeline and an air outlet pipeline; the air inlet pipeline is arranged at the air inlet, and a filter net is arranged at a port of the air inlet pipeline; the air outlet pipeline is communicated with the plasma collaborative photocatalyst reacting part through a distributing pipe; the plasma collaborative photocatalyst reacting part is communicated with an inlet of the adsorbing layer through a collecting pipe; and an outlet of the adsorbing layer is formed in the air outlet. The plasma collaborative photocatalytic air sterilizing and purifying device has the advantages of being short in sterilization time and high in sterilization effect, effectively removing hazardous substances, and being free of secondary pollution and low in energy consumption, and can be applied well to sanitary and medical services, food hygiene, entertainment venues and civilian instruments.
