[0035] like Figure 3 As shown: a discharge cathode 9 is independently fixedly installed in the inner middle part of the dust collecting anode 3, and a high voltage electric field is used to ionize the dust gas. The dust in the airflow is charged and separated from the airflow under the action of the electric field. The dust is adsorbed on the inner wall of the dust collecting anode 3, thereby filtering the dust in the air.

A plurality of openings 15 are also provided at the bottom end of the side wall of the dust collecting anode 3 to improve air circulation. A dust collecting box 10 is provided at the bottom end of the dust collecting anode 3. The dust collecting box 10 is detachably installed inside the housing 1. The top of the dust collecting box 10 is open, vertically corresponding to the dust collecting anode 3, and the open dust collecting box 10 can fully cover the dust collecting anode 3 in the vertical direction. The dust collecting box 10 is used to collect the dust adsorbed on the dust collecting anode 3 by scraping the scraper 11. The dust collecting box 10 is installed in a pull-out manner. The dust collecting box 10 can be directly pulled out from the outside of the housing 1, which is convenient for collecting dust. The design of the scraper 11 and the matching dust box 10 can regularly scrape away the dust adsorbed on the dust collecting anode 3 to ensure the adsorption efficiency of the electrostatic dust removal, thereby improving the dust removal efficiency. In addition, this cleaning method adopts mechanical cleaning, which can operate independently when powered on, does not require other consumables, is easy to use, and solves the disadvantages of existing methods such as water washing that requires an external water source.

[0037] like Figure 3 and 7 As shown: two or more induced draft fans 16 are installed at the bottom of the adsorption chamber 4 for induced air, and an adsorption cylinder 17 is detachably installed on the upper part of the adsorption chamber 4. The induced draft fan 16 is arranged at the rear end of the dust collecting anode 3 to prevent the induced draft fan 16 from contacting a large amount of dust and affecting its use efficiency. The induced draft fan 16 is arranged at the front end of the adsorption cylinder 17 to maximize the suction force of the induced draft fan 16 without being affected by dust, and to prevent the resistance of the adsorption cylinder 17 filtering air from affecting the air input efficiency. The adsorption cylinder 17 adopts formaldehyde-removing activated carbon to adsorb harmful gases in the air. The adsorption cylinder 17 is installed in a plug-in manner. The top of the adsorption chamber 4 is open, and the top cover 2 can be disassembled to replace it. A handle 25 is fixedly installed on the top of the adsorption cylinder 17 to facilitate its installation. The inner wall of the adsorption cylinder 17 is provided with a limiting groove 24 along its height direction, corresponding to the sealing cover 13, to ensure the installation of the adsorption cylinder 17 and the sealing cover 13 limits the adsorption cylinder 17, thereby ensuring the stability of the installation of the adsorption cylinder 17.

[0038] like Figure 3 , 4 , 5 and 8: an air compressor 18 and a semiconductor refrigeration sheet 21 are fixedly installed on the inner top of the condensing chamber 5, a serpentine pipe 19 is laid inside the condensing chamber 5, an electromagnetic valve 23 is installed at the input end of the air compressor 18, the input end of the electromagnetic valve 23 passes through the through hole 7 and is connected to the adsorption chamber 4 but does not cover the through hole 7, the input end of the serpentine pipe 19 is connected to the output end of the air compressor 18, a butterfly valve 20 is installed at the output end of the serpentine pipe 19, and the output end of the butterfly valve 20 passes through the air outlet 8 through the pipe but does not cover the air outlet 8; The air compressor 18 extracts the air in the adsorption chamber 4 that has been adsorbed and purified by the adsorption cylinder 17 into the serpentine pipe 19 and compresses the air to form high-pressure gas. The cold end of the semiconductor refrigeration plate 21 is placed inside the condensation chamber 5, and the semiconductor refrigeration plate 21 is placed on the upper part of the condensation chamber 5. The air entering the condensation chamber 5 passes through the semiconductor refrigeration plate 21 to form cold air and flows to the air outlet 8. The cold air contacts the serpentine pipe 19 to achieve condensation. After the air in the serpentine pipe 19 is condensed at high pressure and low temperature, gaseous pollutants such as toluene, phenol and dimethylaniline in VOCs can be liquefied to reduce the content of gaseous pollutants in the air, thereby achieving air purification. The high-pressure condensation purification time of the air in the serpentine pipe 19 is set at 10-30 minutes. After the purification is completed, the air compressor 18 and the butterfly valve 20 are both opened to discharge the purified air and pass the air to be purified. In the process of high-pressure condensation purification of air, the air that has not entered the serpentine pipe 19 can enter the condensation chamber 5 through the through hole 7 and then be directly discharged from the air outlet 8, which does not affect the dust removal of the device and the continuous adsorption of the adsorption cylinder 17. A temperature sensor 22 is installed inside the condensing chamber 5 for detecting the temperature inside the condensing chamber 5. An independent cavity is also opened at the inner bottom of the shell 1, and a main control system 34 is arranged in the independent cavity. The main control system 34 includes a control center (such as a PLC main control system) and a power supply, which are respectively used to receive data transmitted by all electrical appliances of the device, control the operation of the electrical appliances, and supply power to the electrical appliances of the device.

[0039] like Fig.10 As shown: the hot end of the semiconductor refrigeration sheet 21 is fixedly installed with a heat sink 32, and the outer end of the heat sink 32 is fixedly installed with a heat dissipation fan 33. The output end of the heat dissipation fan 33 is connected to the outside of the housing 1 for heat dissipation. According to the principle of fixed temperature difference between the hot and cold ends of the semiconductor refrigeration sheet 21, the heat dissipation fan 33 reduces the hot end temperature of the semiconductor refrigeration sheet 21 to reduce the cold end temperature of the semiconductor refrigeration sheet 21. The cold end temperature of the semiconductor refrigeration sheet 21 is regulated to achieve condensation temperature regulation in the condensation chamber 5. The semiconductor refrigeration sheet 21 and the heat dissipation fan 33 are adapted to the temperature sensor 22 through the main control system 34. The temperature sensor 22 monitors the temperature in the condensation chamber 5, and the cooling fan 33 starts, shuts down or changes the wind speed to adjust the temperature of the cold end of the semiconductor refrigeration plate 21, so as to keep the temperature in the condensation chamber 5 stable. According to the boiling point of toluene of about 110°C and the condensation and liquefaction temperature below 10°C, the boiling point of phenol of about 182°C and the condensation and liquefaction temperature below 30°C, the boiling point of dimethylaniline of about 193°C and the condensation and liquefaction temperature below 30°C, and formaldehyde liquefies below -19.5°C, the temperature in the condensation chamber 5 is set to be maintained below -20°C to liquefy the main pollutants such as toluene, phenol, dimethylaniline and formaldehyde in the air, so as to purify the harmful air.

[0040] like Fig. 9As shown: a sealing cover 27 is placed on the top of the dust box 10, and the sealing cover 27 is independently set to seal and cover the top opening of the dust box 10, and also includes a rotating shaft 28, the axis of the rotating shaft 28 is vertically set, and is independently rotatably installed inside the housing 1, the side of the sealing cover 27 is fixedly connected to the rotating shaft 28, and a small gear 29 is coaxially fixedly connected to the rotating shaft 28, and the small gear 29 is meshedly connected to the large gear 30, and the large gear 30 is coaxially connected to the motor 31, and the motor 31 is independently fixed, and the rotating shaft of the valve plate of the butterfly valve 20 is vertical and coaxially connected to the large gear 30; The motor 31 starts to drive the large gear 30 to rotate to open or close the butterfly valve 20, and drives the small gear 29 meshing with the large gear 30 to rotate to rotate the sealing cover 27, so as to open or seal the top opening of the dust box 10. The drive mechanism 26 composed of the rotating shaft 28, the small gear 29, the large gear 30 and the motor 31 is adapted to realize that the butterfly valve 20 and the sealing cover 27 on the top of the dust box 10 are driven by the same motor 31, thereby reducing the use of driving components. When the butterfly valve 20 is opened to discharge the condensed and purified air, the sealing cover 27 is driven to open, and the electric linear slide 12 is adapted to realize the synchronous self-cleaning of the dust collected in the dust collecting anode 3, and multiple operating mechanisms work together and connect in the same time period, thereby reducing the use of timing components and the design of independent programming.

[0041] like Figure 1 As shown: the housing 1 is provided with a plurality of heat dissipation openings 36, which correspond to the air compressor 18, the heat dissipation fan 33 and the main control system 34 respectively, for heat dissipation.

[0042] The operation process of the filtering device is as follows: the equipment is started, the dust collecting anode 3 and the discharge cathode 9 continue to work to absorb dust, the induced draft fan 16 starts to induce air, the semiconductor refrigeration sheet 21 and the cooling fan 33 start cooling, the air compressor 18 starts to exhaust air, the motor 31 starts to drive the butterfly valve 20 and the sealing cover 27 to open, the butterfly valve 20 opens for 1-2 minutes, and the opening time of the butterfly valve 20 is determined according to the length of the serpentine pipe 19, so that the drawn air flows from the input end of the serpentine pipe 19 to the output end, the butterfly valve 20 is closed after opening for a specified time, and the sealing cover 27 is closed accordingly, and the air compressor 18 continues to work to pass air into the serpentine pipe 19 to form high-pressure gas and then closes, and the high pressure is set at 0.5 to 2.0 MPa, the high-pressure air in the serpentine pipe 19 is condensed and purified for 10-30 minutes. During the condensation process, the induced draft fan 16 continuously induces air, and the air that has not entered the serpentine pipe 19 is dusted by the dust collecting anode 3 and adsorbed and purified by the adsorption cylinder 17, and then enters the condensation chamber 5 and is directly discharged from the air outlet 8. After the condensation time is reached, the induced draft fan 16 stops running, the motor 31, the air compressor 18, and the electric linear guide 12 are started, the motor 31 drives the butterfly valve 20 and the sealing cover 27 to open, the air compressor 18 introduces fresh air, and the condensed and purified air is discharged by the butterfly valve 20, and the fresh air enters the serpentine pipe 19, and the electric linear guide 12 is started. The linear slide 12 drives the scraper 11 to move from top to bottom to scrape the dust adsorbed on the dust collecting anode 3 and drop it into the dust collecting box 10 for collection. After the butterfly valve 20 is opened for 1-2 minutes, the motor 31 starts to control the butterfly valve 20 and the sealing cover 27 to close, and the induced draft fan 16 continues to run. The electric linear slide 12 drives the scraper 11 to move upward to the top, and the air compressor 18 continues to work to introduce air into the serpentine pipe 19 to form high-pressure gas and then closes to form a circulating working state, thereby realizing dust removal, adsorption purification, high-pressure condensation to remove harmful gases in the air of the indoor air, and realizing self-cleaning of air dust removal.
