Description

Technical Field

[0001] The invention relates to the technical field of waste gas separation and treatment, and in particular to a waste gas filtering device and method for chemical equipment. Background Art

[0002] Chemical waste gas refers to the toxic and harmful gases discharged by chemical plants during chemical production. In the process of producing and processing chemicals or other products by industrial boilers in chemical plants, a large amount of waste gas will be generated. At this time, in order to ensure that the waste gas meets the emission standards when it is discharged, the waste gas generated needs to be separated and filtered.

[0003] The existing Chinese patent application with application publication number CN118217736A discloses an exhaust gas filter device for chemical equipment, comprising a filter box, a support leg fixedly mounted on the bottom of the filter box, a pad fixedly mounted on the bottom of the filter box, and a filter assembly arranged at the side wall of the filter box, wherein the filter assembly comprises a transport mechanism installed at the side wall of the filter box, the transport mechanism is located at the top of the filter box, a cleaning mechanism is installed on the side wall of the filter box, one end of the cleaning mechanism is connected to the side wall of the transport mechanism, and a mounting mechanism is installed at the inner wall of the filter box; the invention can effectively promote the position of the fan blade to rotate, and the fan blade can effectively brush the side wall of the filter plate under the joint action of the reciprocating screw rod, the connecting block, the cross plate and the brush, and the brush can effectively brush the side wall of the filter plate, effectively brush the dust on the surface of the filter plate, and improve the filtering effect of the filter plate.

[0004] However, the exhaust gas filter has the following defects when used: 1. When separating and filtering impurities in the exhaust gas, the existing exhaust gas filtration device needs to go through pre-treatment, deep purification and post-treatment to fully separate the impurities in the exhaust gas. At this time, the traditional solution requires a long time to separate various impurities in the exhaust gas, resulting in low efficiency and poor effect in the separation and treatment of the exhaust gas. When performing pre-treatment, deep purification and post-treatment of the exhaust gas at the same time, multiple driving parts need to be driven separately, resulting in large vibration and noise during the operation of the device, affecting the environment for exhaust gas treatment; 2. When the existing exhaust gas filter device processes organic matter in the exhaust gas, it generally uses activated carbon adsorption to adsorb organic matter. However, when the traditional method is used, the organic matter in the activated carbon will adhere to its internal channels after long-term use, affecting the effect of the activated carbon in adsorbing and separating impurities in the exhaust gas. At the same time, when separating the particulate matter in the exhaust gas to achieve the pretreatment operation of the exhaust gas, the particulate matter is easy to adhere to the surface of the screen, affecting the effect of the filter screen on separating and filtering the particulate matter in the flue gas.

In addition, through intermittent cleaning and the collision rubber block made of rubber material, the degree of damage to the filter screen caused by the collision can be reduced, effectively improving the service life of the filter screen; 2. In the waste gas filtering device and method for chemical equipment, when the waste gas generated by the industrial boiler of the chemical plant is purified and separated (through the activated carbon adsorption ball), the middle rolling rod that drives the spiral auger blades to rotate can also drive the two spiral circulation augers installed at the bottom to rotate, and drive the deodorizing balls moved to the side of the spiral circulation augers to move upward, so as to ensure that the deodorizing balls can continuously move up and down, expand the contact area between the deodorizing balls and the gas, and improve the deodorizing effect and efficiency of the deodorizing balls on the odor in the waste gas; 3. In the waste gas filtration device and method of chemical equipment, the waste gas treatment channel arranged in a Z shape ensures that the waste gas can fully flow inside each box, and effectively increases the length of the waste gas flow, thereby ensuring the effect of waste gas treatment. At the same time, when the waste gas is being treated, the gas inside the waste gas separation box can be extracted and moved to the inside of the waste gas post-treatment box through two blast blades rotating in opposite directions, thereby accelerating the flow rate of the waste gas. In addition, the operations of separating and adsorbing particulate matter, organic matter and odor in the waste gas can be carried out at the same time, thereby maximizing the efficiency of waste gas treatment; 4. In the waste gas filtration device and method of chemical equipment, when separating, filtering and purifying the waste gas generated by the industrial boiler of the chemical plant, the particulate matter, organic matter and odor in the waste gas can be separated and adsorbed in turn, fully realizing the separation of impurities in the waste gas, ensuring that when the waste gas is subsequently discharged into the atmosphere, the harmful parts in the waste gas will not pollute the atmosphere. At the same time, the separation and adsorption of particulate matter, organic matter and odor in the waste gas can be achieved through the operation of a set of driving parts (DC motor). The vibration and noise generated by the device during waste gas treatment are low, and its working environment is more comfortable. BRIEF DESCRIPTION OF THE DRAWINGS
