Description

Technical Field

[0001] This invention belongs to the technical field of waste gas treatment equipment, specifically relating to a VOCs waste gas treatment equipment for green island construction. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life, especially those emitted by chemical plants, steel plants, pharmaceutical plants, coking plants, and oil refineries. These waste gases have strong odors and seriously pollute the environment and affect human health.

[0003] VOCs, as an important component of waste gas, refer to organic compounds that have high saturated vapor pressure, low boiling point, small molecular weight under standard conditions, and are easily volatilized at room temperature. Furthermore, volatile organic compounds are important precursors to secondary pollutants such as fine particulate matter and ozone, thereby contributing to atmospheric environmental problems such as haze and photochemical smog.

[0004] Therefore, there is an urgent need for a VOCs waste gas treatment device for green island construction to treat the VOCs in the waste gas.

[0005] A patent with publication number CN117619143A discloses a VOCs waste gas treatment device and method for green island construction. It includes a circulating lifting belt, a guide pipe, a mixing catalytic mechanism, an atomizing box, an atomizer, an atomizing plate, a filter frame, a second drive motor, and a cam. In operation, the circulating lifting belt and guide pipe circulate and transport the catalyst, ensuring it is transported along with the waste gas to the mixing catalytic mechanism for reaction. The reacted waste gas enters the atomizing box, where the atomizer is activated, spraying water mist through the atomizing plate. This water mist combines with particulate matter in the reacted waste gas and, together with the filter screen on the filter frame, adsorbs and filters it, allowing the purified gas to be discharged through the outlet pipe. Furthermore, the second drive motor can be activated to rotate the cam, causing the filter frame to vibrate for a cleaning effect.

[0006] However, the above solution requires not only an atomizer to spray water mist into the atomization box when treating exhaust gas, but also a second drive motor to drive the filter frame to shake. The above process requires the use of more drive sources, which not only increases production and maintenance costs, but also increases the difficulty of constructing the control system, and the practical effect is generally average. Summary of the Invention

One end of the connecting rod 24 is fixedly connected to the extrusion plate 27, and the other end of the connecting rod 24 is fixedly mounted with an arc-shaped block 26. A first spring 25 is sleeved on the outer surface of the connecting rod 24. One end of the first spring 25 is fixedly connected to the support plate 37, and the other end is fixedly connected to the arc-shaped block 26. The outer surface of the rotating tube 19 is fixedly sleeved with the cam 23, and the cam 23 and the arc-shaped block 26 are in contact transmission engagement.

[0046] The second transmission component includes a first arc plate 32, which is fixedly sleeved on the outer surface of the rotating tube 19. A second arc plate 36 is fixedly installed on the filter plate 34, and the first arc plate 32 and the second arc plate 36 are in contact transmission cooperation. A second spring 33 is provided between the filter plate 34 and the atomizing box 13. One end of the second spring 33 is fixedly connected to the filter plate 34, and the other end is fixedly connected to the inner wall of the atomizing box 13.

[0047] Furthermore, an air outlet pipe 15 is fixedly installed on the atomizing box 13;

[0048] Furthermore, a collection chamber 35 is slidably inserted into the atomizing box 13, and the collection chamber 35 is located below the filter plate 34.

[0049] Working principle: When in use, start the fan and conveyor 5. The fan will transport the exhaust gas to the closed box 2. The conveyor 5 will transport the catalyst in the receiving box 17 to the closed box 2 in sequence through the conveying cylinder 4 and the conveying pipe 6. The exhaust gas and the catalyst will enter the rotating cylinder 9 together through the feeding pipe 7, thereby catalyzing the VOCs exhaust gas and converting the harmful gases.

[0050] Subsequently, the first motor 14 is started, and the output shaft of the first motor 14 drives the rotating drum 9 and the stirring rod 11 inside the rotating drum 9 to rotate, so that the catalyst is stirred in the rotating drum 9 to fully catalyze the VOCs waste gas to react. Since the inner wall of the rotating drum 9 is inclined, excess catalyst enters the discharge pipe 12. When the discharge pipe 12 is connected to the circulation pipe 16, the catalyst will enter the receiving box 17 through the circulation pipe 16 for recycling.

[0051] The waste gas after the reaction is discharged through the vent 10, and then enters the atomizing box 13 through the funnel 18 and the rotating tube 19.

[0052] Subsequently, the second motor 21 is started, and the output shaft of the second motor 21 drives the second gear 22 to rotate. The second gear 22 drives the first gear 20 to rotate, so that the rotating tube 19 rotates synchronously, and the exhaust gas is evenly filtered from the surface of the filter plate 34.

[0053] At the same time, the rotation of the rotating tube 19 will also drive the cam 23 to rotate. During the rotation of the cam 23, it will contact the arc block 26, thereby pushing the connecting rod 24 to slide in the direction of squeezing the first spring 25 through the arc block 26. Then, with the help of the squeezing plate 27, the air bag 28 is squeezed, so that the water in the air bag 28 enters the atomizing plate 38 through the connecting tube 30 and sprays water mist from the atomizing nozzle 31 on the atomizing plate 38. The water mist combines with the particulate matter in the VOCs waste gas after the reaction, and works with the filter plate 34 to adsorb and filter. The purified gas is discharged through the exhaust pipe 15.

[0054] When the cam 23 disengages from the arc block 26, the connecting rod 24 slides back to its original position under the elastic action of the first spring 25, and the airbag 28 resets under its own elastic action and the pull of the squeezing plate 27, so that the water in the water tank 29 enters the airbag 28 through the connecting pipe 30 for the next spraying operation.

[0055] In addition, the rotation of the rotating tube 19 will also drive the first arc plate 32 to rotate. Through the cooperation of the first arc plate 32 and the second arc plate 36, and with the help of the elasticity of the second spring 33, the filter plate 34 will shake up and down repeatedly, thereby dropping the dust and other impurities on the surface of the filter plate 34 into the collection chamber 35.

[0056] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
