There is a bar-shaped outlet 5 on the upper box body 4 on the top side of the box body, and the inside of the bar-shaped air outlet 5 is provided with a negative electrode discharge wire 3 . A wind barrier 6 fixed on the upper box body 4 is arranged below the air outlet 5 , and the cavity between the wind barrier 6 and the upper box body 4 is filled with a sound-absorbing material 7 . The vertical electrostatic precipitating part 11 is in the insulating frame 17, and is filled with straight-through tubes 21 equal to the insulating frame 17. Each straight-through tube 21 has a discharge wire 20 and a spring 19 connected to the discharge wire 20 in a straight line. The straight cylinder 21 can be a regular hexagonal cylinder, a square cylinder, a parallelogram cylinder, or a cylinder. An inner cylinder 22 is arranged between the air outlet end of the straight-through cylinder 21 and the periphery of the discharge wire 20 in the middle. As shown in Figure 3 and Figure 4, the molecular sieve adsorption part 10 is made of a metal frame 25 and a metal mesh 26 fixed on its upper and lower sides respectively, and its built-in is filled with sodium-X type (10X) molecular sieve 23 or other special molecular sieves. The wire mesh 26 is at the same potential as the straight-through cylinder 21 through the metal frame 25, so that the smoke and dust are trapped again.

The activated carbon adsorption part 9 is formed by placing fibrous or honeycomb activated carbon 24 in a plastic frame. Ultraviolet sterilizing part 8 is to be contained on the plastic frame by ultraviolet lamp and forms. The vertical electrostatic precipitator insulating frame 17, metal frame 25, plastic frame of activated carbon adsorption part 9, ultraviolet light frame etc. have the same size in cross section.
