[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-4The utility model provides an embodiment: an energy-saving low-temperature plasma VOCs waste gas treatment device, including a treatment box 1, an air intake box 2 is fixedly installed above the treatment box 1, a partition 6 is fixedly installed in the middle of the air intake box 2, and the interior of the air intake box 2 is symmetrically provided with filter boxes 8 along both sides of the partition 6. There are two filter boxes 8 on each side of the partition 6, and a square gasket frame 9 is provided below the filter box 8 to support the filter box 8. The square gasket frame 9 is fixedly connected to the air intake box 2, and the interior of the air intake box 2 is symmetrically rotatably provided with adjustment plates 7 along both sides above the partition 6.

[0024] During use, a dual-channel exhaust gas flow path is formed inside the air intake box 2 by setting a partition 6 and two rotatable adjustment plates 7, and a filter box 8 is set in each channel, so that the VOCs exhaust gas can be filtered before low-temperature plasma treatment to remove impurities in the VOCs exhaust gas, so as to reduce the burden of subsequent low-temperature plasma treatment and improve energy saving. The dual-channel setting in the air intake box 2 can use a single-channel circulation method to filter when the VOCs exhaust gas flows through the filter. When the filter box 8 in one channel accumulates too many impurities and needs to be cleaned, the channel can be closed and the other channel can be started. At this time, the filter box in the channel can be cleaned, and then through the alternating use of the dual channels, the VOCs exhaust gas can be circulated while the filter box 8 is cleaned, which is beneficial to the continuous treatment of VOCs exhaust gas and increases practicality.

[0025] Furthermore, the filter box 8 includes a surrounding frame 801, an annular top plate 802, a conical filter plate 803 and a collection frame 804. The conical filter plate 803 is fixedly installed on the outside of the annular top plate 802, the collection frame 804 is fixedly installed on the outside of the conical filter plate 803, the surrounding frame 801 is fixedly installed on the outside of the collection frame 804, and an arc-shaped groove 8041 is provided on the upper end surface of the collection frame 804. Through the conical setting of the filter plate, during the VOCs exhaust gas filtration process, the flow impact of the exhaust gas can conveniently blow the impurities on the surface of the conical filter plate 803 to the bottom, which is beneficial to the collection of impurities on the collection frame 804 and increases practicality.

[0026] Furthermore, a column 12 is fixedly installed below the annular top plate 802, and a square platform 13 is fixedly installed below the column 12. Mounting rods 14 are fixedly installed at the front end, rear end and both sides of the square platform 13. The end of the mounting rod 14 away from the square platform 13 is fixedly connected to the frame 801. The arranged columns 12, square platform 13 and mounting rods 14 can support the annular top plate 802 to increase the structural strength.

[0027] Furthermore, sealing plates 5 are symmetrically provided on both sides of the air intake box 2. One end of the sealing plate 5 is inserted into the interior of the air intake box 2 and contacts with the partition 6. The sealing plate 5 is movably provided and can be pulled out from the air intake box 2. A pad 10 is provided under the sealing plate 5, and the pad 10 is fixedly connected to the partition 6. The two sealing plates 5 provided facilitate the opening and closing of the two exhaust gas channels inside the air intake box 2, thereby increasing practicality.

[0028] Furthermore, a plurality of covers 4 are fixedly installed at the lower part of the front end of the air intake box 2. The covers 4 correspond to the positions of the filter box 8, which makes it convenient to remove the covers 4 and take out the filter box 8 for cleaning. An electric motor 3 is fixedly installed above the front end of the air intake box 2, and two electric motors 3 are provided. The output ends of the two electric motors 3 are respectively fixedly connected to the two adjustment plates 7, so that the electric motor 3 can drive the adjustment plates 7 to rotate, which facilitates the adjustment of the opening and closing of the two exhaust channels inside the air intake box 2, thereby increasing practicality.

[0029] Furthermore, a plasma processing chamber 15 is provided inside the processing box 1, and a pole plate 16 is fixedly installed above the inside of the plasma processing chamber 15, and a pole plate 2 17 is fixedly installed below the inside of the plasma processing chamber 15. The pole plate 16 is a positive pole plate, and the pole plate 2 17 is a negative pole plate. The pole plate 16 and the pole plate 2 17 are both electrically connected to the control terminal of the VOCs waste gas treatment, so as to facilitate the regulation of the voltage of the pole plate 16 and the pole plate 2 17 after being energized. A fan 18 is fixedly installed along one side of the plasma processing chamber 15 inside the processing box 1, so that by energizing and applying voltage to the pole plate 1 16 and the pole plate 2 17 inside the plasma processing chamber 15 respectively, the gas between the pole plates is broken down to generate micro-discharges. These micro-discharges are randomly distributed to form a low-temperature plasma area to treat the circulating VOCs waste gas.

[0030] Furthermore, organic waste gas detectors 11 are symmetrically fixedly installed below both sides of the partition 6, which can detect the pollution concentration of the input VOCs waste gas. Organic waste gas detectors 19 are symmetrically fixedly installed at the rear end and front end inside the plasma treatment chamber 15, which can detect the pollution concentration of the output VOCs waste gas to detect whether it meets the standard. By setting up two organic waste gas detectors, it is convenient to detect the pollution concentration before and after the VOCs waste gas treatment, and the control terminal of the VOCs waste gas treatment can adjust the voltage of the electrode plate 16 and the electrode plate 2 17 after power is turned on according to the needs of the treatment, thereby increasing the energy saving of the treatment equipment and improving practicality.

[0031] Working principle: When in use, VOCs waste gas is input into the air inlet box 2, flows through a channel on the side of the partition 6, and is filtered and treated by the conical filter plate 803 in the filter box 8 to remove impurities, reduce the burden of subsequent low-temperature plasma treatment, and improve energy saving. Then the VOCs waste gas enters the treatment box 1, and voltage is applied to the electrode plate 1 16 and the electrode plate 2 17 inside the plasma treatment chamber 15 respectively. The gas between the electrodes is broken down and micro-discharges are generated. These micro-discharges are randomly distributed to form a low-temperature plasma area to treat the circulating VOCs waste gas, and then the waste gas is output under the operation of the fan 18.
