The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In an embodiment, referring to fig. 1 to 3, a first chute 12 is disposed inside the electric control outer frame 1, the primary net 3 includes an outer frame 31 and a net surface 32, and the outer frame 31 is slidably connected to the first chute 12.

In an embodiment, referring to fig. 1 to 3, the dust removing section 22 is at least one of a honeycomb high-voltage electrostatic module, a plate high-voltage electrostatic module, a stationary electrode module and a fiber filtering module, the chemical pollutant removing section 23 is at least one of a photocatalytic module, a cold catalyst module and an activated carbon module, and the modules in the chemical pollutant removing section 23 are sequentially arranged.

The operation principle is as follows: firstly, the dust removal section comprises a honeycomb high-voltage electrostatic module, a plate-type high-voltage electrostatic sterilization dust removal module, a stationary electrode filtering module and a fiber filtering module, and then at least one of the modules is selected according to the advantages of each module;

the honeycomb high-voltage electrostatic module: the honeycomb type high-voltage electrostatic sterilization and dust removal section is required to produce two electric fields, wherein one electric field charges dust in the air and is called as a charged electric field; the other electric field separates and collects the charged dust particles and is called as a separation electric field. The discharge electrode (metal needle) of the charge field is connected with the positive electrode of the high-voltage direct-current power supply, and the dust collecting electrode (honeycomb shape) of the separation field is grounded as the negative electrode. Upon application of power, a non-uniform electric field is established between the cathode and the anode, with the electric field surrounding the anode being at a maximum. When the air surrounding the discharge electrode is fully ionized, a corona is generated. The corona range of the discharge electrode (metal needle) is usually only a few millimeters around. Because the range of the corona area is very small, only negative ions enter the corona inner area, and a small amount of dust particles pass through the corona inner area to obtain negative charges which are deposited on the corona electrode. The positive ions enter the corona outer zone and collide with the corona outer zone through dust particles, so that the dust particles in the air are positively charged and are captured on the dust collecting plate, and the purpose of purifying the air is achieved.

The plate-type high-voltage electrostatic sterilization and dust removal module comprises: when gas containing dust particles in the air passes through the purification device, firstly large particles can be intercepted and filtered by the primary filter, and continue to move to a high-voltage electric field formed between an anode wire (discharge anode) connected with a high-voltage direct-current power supply and a grounded cathode plate (cathode plate), the gas can be quickly ionized due to corona discharge generated by the anode, at the moment, according to the positive and negative attraction principle, positively charged particles collide against the cathode plate under the action of strong electric field force and are adsorbed and precipitated on the cathode plate, and due to the fact that a tiny potential difference exists between cell nucleuses and cell membranes of bacteria in the movement process, the positively charged particles can be caught and killed by energy instantaneously released by high-voltage charges, biological activity is lost, and the gas is thoroughly killed, and the purposes of dust removal and sterilization are achieved.

The electret filter module: the trapping force is mainly the coulomb force and the induced force of the charged fiber to the particles (charged or uncharged particles). The electrostatic reinforced fiber filtration adopts pre-charge or external electric field to realize the purposes of enhancing efficiency and reducing resistance, but if the external electric field is removed, the time for the fiber to keep the charge is very short, or the residual charge quantity is attenuated quickly. While the electret filter material is capable of long-term storage of space charge. By applying an electric field to the dielectric material and adopting a certain physical and chemical method to make the charge or electric polarization state stay on the electrolyte for a long time, a long-life electrode can be made.

The fiber filtration module: the fiber filtration technology mainly adopts a filtration and separation method: through setting up the filter of different performance, remove the suspended dust particle and the microorganism in the air, promptly through the filter material with dust particle entrapment. The filtering material used by the dust collector is fiber with a smaller diameter, so that the air flow can smoothly pass through the dust collector, and the dust collector can effectively collect dust particles

The cold catalyst module, cold catalyst, also known as natural catalyst, is a new kind of air purification material after photocatalyst deodorization air purification material, can play catalytic reaction under the normal atmospheric temperature condition, make multiple harmful odorous gas decompose into harmless tasteless substance under normal atmospheric temperature and normal pressure, change into chemical adsorption by simple physical adsorption, decompose while adsorbing, get rid of harmful gas such as formaldehyde, benzene, xylol, toluene, TVOC, generate water and carbon dioxide, in the catalytic reaction process, cold catalyst itself does not directly participate in the reaction, the cold catalyst does not change after the reaction and does not lose, play a role for a long time. The cold catalyst is non-toxic, non-corrosive and non-combustible, the reaction product is water and carbon dioxide, no secondary pollution is generated, and the service life of the adsorption material is greatly prolonged.
