Description

Technical Field

[0001] This invention relates to the field of waste gas absorption technology, specifically to a device and method for efficiently absorbing chemical organic waste gas. Background Technology

[0002] Chemical industry is an abbreviation for chemical process, chemical industry, chemical engineering, etc. All technologies that use chemical methods to change the composition or structure of substances or synthesize new substances belong to chemical production technology, that is, chemical process, and the products obtained are called chemical products. During the production of chemical products, a large amount of organic waste gas is generated. The emitted waste gas has a strong odor and contains a variety of pollutants with varying toxicities. In the existing technology, Chinese utility model patent CN218573273U discloses a composite chemical absorption organic waste gas treatment device. Addressing the problems of existing methods that use a single-direction spraying agent to treat waste gas, making it difficult to achieve uniform contact between the agent and the waste gas, and the inflexibility of replacing the filter media for waste gas purification, the following solution is proposed: It includes a treatment box one, a mixing connecting pipe, a treatment box two, two spraying components, and two purification components. Each of the treatment boxes one and two has mounting holes on one side. The two ends of the mixing connecting pipe are respectively fixedly installed in the two mounting holes. An air inlet pipe is fixedly installed on one side of the treatment box one. Both spraying components are located in the treatment box one, and both purification components are located in the treatment box two. This utility model's waste gas treatment equipment can fully spray the waste gas, ensure uniform contact between the agent and the waste gas, and allow for flexible replacement of the filter media for waste gas purification. In the above technology, the liquid medicine enters the rotating tube through the fixed tube and is sprayed out onto the spray plate to fully spray the organic waste gas. However, the organic waste gas contains a large amount of dust and particulate impurities. When spraying the organic waste gas containing dust and particulate impurities directly, the dust and particulate impurities will drip down with the liquid medicine, making it impossible to reuse the liquid medicine directly in the future.

A delivery pump is connected to either the first connecting pipe or the second connecting pipe.

[0013] Furthermore, the method for efficiently absorbing chemical organic waste gas includes the following steps: Filtration of organic waste gas: Connect the organic waste gas inlet to the organic waste gas outlet. The organic waste gas is discharged into the interior of the organic waste gas treatment box through the organic waste gas inlet. During discharge, the first filter screen inside the organic waste gas inlet filters the organic waste gas. Cleaning of the first filter: When organic waste gas is discharged into the organic waste gas treatment box through the first filter, the organic waste gas drives the second connecting plate to rotate through the cooperation of the fan blades and the rotating shaft. At this time, the elastically set first scraper cleans the dust and impurity particles filtered out by the first filter. Dust and impurity particle collection: When the first scraper cleans the surface of the first filter screen, dust and impurity particles will accumulate on the surface of the first scraper and be transported to the inside of the collection box through the first and second channels under the conveying of organic waste gas. Cleaning dust and impurities inside the collection box: When it is necessary to clean the dust and impurities inside the collection box, remove the first filter screen from the organic waste gas inlet using the fixing plate, and then remove the collection box from the placement chamber. During removal, the squeezing plate is no longer squeezed, and the gas inside the second gas storage bladder can be discharged into the first gas storage bladder. The baffle extends under the action of the second return spring, blocking the second passage to prevent dust and impurities from leaking out during the removal process. After removing it to a suitable position for dumping dust, squeeze the squeezing plate again to raise the baffle, at which point the dust and impurities inside the collection box can be discharged from the second passage. Absorption of organic waste gas: The filtered organic waste gas is discharged into the organic waste gas treatment box through the organic waste gas inlet. During discharge, the liquid medicine inside the collection box is transported to the spray plate through the cooperation of water pump and delivery pipe, and sprayed out by nozzles, so that the liquid medicine mixes with the organic waste gas and treats the organic waste gas. During the spraying process, the motor is started, and the motor drives the spray plate to rotate, increasing the spraying area and making the liquid medicine come into closer contact with the organic waste gas. Filtration of the sprayed medicine: The sprayed medicine is collected in a collection tank. To prevent impurities from entering the sprayed medicine, a second filter screen is installed inside the collection tank. The medicine is filtered through the second filter screen. At the same time, a sliding first connecting plate is installed on the second filter screen. Through the cooperation of a transmission screw and an output motor, a second scraper, which is elastically connected to the first connecting plate, moves along the surface of the second filter screen to clean the impurities filtered out by the second filter screen. Heating of organic waste gas: The organic waste gas mixed with the liquid medicine is transported to the interior of the organic waste gas inlet through the heating plate. When passing through the heating plate, the organic waste gas is heated and some toxic gases are released by heating. Absorption of toxic gases: Organic waste gas that has been heated and decomposed into toxic gases can be adsorbed by the adsorption plate, and then discharged through the organic waste gas inlet.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention filters organic waste gas through a first filter screen. When the organic waste gas is discharged into the organic waste gas treatment box through the first filter screen, the organic waste gas drives the second connecting plate to rotate through the cooperation of the fan blades and the rotating shaft. At this time, the elastically set first scraper cleans the dust and impurity particles filtered out by the first filter screen. When the first scraper cleans the surface of the first filter screen, the dust and impurity particles will accumulate on the surface of the first scraper and be transported to the collection box through the first channel and the second channel under the transport of the organic waste gas. 2. Organic waste gas is discharged into the organic waste gas treatment box through the organic waste gas inlet. During discharge, the liquid medicine inside the collection box is transported to the spray plate through the cooperation of water pump and delivery pipe, and sprayed out by nozzles, so that the liquid medicine mixes with the organic waste gas to treat the organic waste gas. The sprayed liquid medicine is collected through the collection box. A second filter screen is set inside the collection box to filter the liquid medicine. At the same time, a sliding first connecting plate is set on the second filter screen. Through the cooperation of transmission screw and output motor, the second scraper elastically connected to the first connecting plate moves along the surface of the second filter screen to clean the impurities filtered out by the second filter screen. 3. Spiral heat exchange tubes are installed inside both the organic waste gas inlet and outlet, and are connected through the first and second connecting pipes. When the organic waste gas heated by the heating plate passes through the outlet, the spiral heat exchange tubes inside the outlet exchange heat with the heated organic waste gas. With the cooperation of the spiral heat exchange tubes inside the organic waste gas inlet, the organic waste gas entering the organic waste gas treatment box is preheated, so that the water vapor in the organic waste gas is evaporated, preventing the water in the organic waste gas from adhering to the surface of the first filter screen and causing dust and water to mix and form mud.

In this embodiment: the filtered organic waste gas is discharged into the organic waste gas treatment box 1 through the organic waste gas inlet 2. During discharge, the liquid medicine inside the collection box 13 is transported to the spray plate 18 through the cooperation of the water pump 8 and the delivery pipe 9, and is sprayed out by the nozzle 43, so that the liquid medicine mixes with the organic waste gas to treat the organic waste gas. During the spraying process, the motor 7 is started, and the motor 7 drives the spray plate 18 to rotate, increasing the spraying area and making the liquid medicine and organic waste gas come into closer contact.

[0022] like Figure 2 As shown, the equipment and method for efficiently absorbing chemical organic waste gas disclosed in Embodiment 5 of the present invention have a structure that is basically the same as that in Embodiment 4, except that: A heating plate 16 is installed inside the organic waste gas treatment box 1 on one side corresponding to the collection box 13, and an adsorption plate 17 is provided inside the exhaust port 3 on one side corresponding to the heating plate 16. Both the organic waste gas inlet 2 and the exhaust outlet 3 are equipped with spiral heat exchange tubes 6. The inlet and outlet ends of the two sets of spiral heat exchange tubes 6 are connected through the first connecting pipe 4 and the second connecting pipe 5, respectively. A delivery pump is connected to the first connecting pipe 4 or the second connecting pipe 5. In this embodiment: the organic waste gas mixed with the drug solution is transported to the interior of the organic waste gas inlet 2 through the heating plate 16. When passing through the heating plate 16, the organic waste gas is heated by the heating plate 16, and some toxic gases are heated and decomposed. Absorption of toxic gases: The organic waste gas that has been heated and decomposed into toxic gases can be adsorbed by the adsorption plate 17, and after adsorption, it is discharged through the organic waste gas inlet 2. When the organic waste gas heated by the heating plate 16 passes through the inside of the exhaust port 3, the spiral heat exchange tube 6 inside the exhaust port 3 exchanges heat with the heated organic waste gas. With the cooperation of the spiral heat exchange tube 6 inside the organic waste gas inlet 2, the organic waste gas entering the organic waste gas treatment box 1 is preheated, so that the water vapor in the organic waste gas is evaporated, preventing the water in the organic waste gas from adhering to the surface of the first filter screen 12, causing dust and water to mix and form mud.

[0023] Specifically, this solution involves connecting the organic waste gas inlet 2 to the organic waste gas discharge end, allowing the organic waste gas to be discharged into the interior of the organic waste gas treatment box 1 through the organic waste gas inlet 2. During discharge, the first filter screen 12 inside the organic waste gas inlet 2 filters the organic waste gas. When the organic waste gas is discharged into the organic waste gas treatment box 1 through the first filter screen 12, the organic waste gas drives the second connecting plate 21 to rotate through the cooperation of the fan blade 19 and the rotating shaft 20. At this time, the elastically set first scraper 24 cleans the dust and impurity particles filtered out by the first filter screen 12. When the first scraper 24 cleans the surface of the first filter screen 12, dust and impurity particles will accumulate on the surface of the first scraper 24 and be transported to the inside of the collection box 25 through the first channel 27 and the second channel 30 under the transport of organic waste gas. Cleaning of dust and impurities inside the collection box 25: When it is necessary to clean the dust and impurities inside the collection box 25, the first filter screen 12 is removed from the organic waste gas inlet 2 through the fixing plate 11, and then the collection box 25 is removed from the placement cavity 50. When it is removed, the squeezing plate 36 is no longer squeezed. At this time, the gas inside the second air storage bag 40 can be discharged into the first air storage bag 35. The baffle 32 extends under the action of the second return spring 33 to block the second passage 30, preventing the dust and impurities inside the collection box 25 from leaking out during the removal process. After removing it to a suitable position for dumping dust, squeezing the squeezing plate 36 again will raise the baffle 32. At this time, the dust and impurities inside the collection box 25 can be discharged from the second passage 30. The filtered organic waste gas is discharged into the organic waste gas treatment box 1 through the organic waste gas inlet 2. During discharge, the liquid medicine inside the collection box 13 is transported to the spray plate 18 through the cooperation of the water pump 8 and the delivery pipe 9, and is sprayed out by the nozzle 43, so that the liquid medicine mixes with the organic waste gas and treats the organic waste gas. Start motor 7, which drives spray plate 18 to rotate, increasing the spray area and making the liquid medicine come into closer contact with the organic waste gas; The sprayed medicine is collected in the collection box 13. To prevent impurities from entering the sprayed medicine, a second filter screen 14 is installed inside the collection box 13. The medicine is filtered through the second filter screen 14. At the same time, a sliding first connecting plate 15 is installed on the second filter screen 14. Through the cooperation of the transmission screw 49 and the output motor, the second scraper 45, which is elastically connected to the first connecting plate 15, moves along the surface of the second filter screen 14 to clean the impurities filtered out by the second filter screen 14. The organic waste gas mixed with the drug solution is transported to the interior of the organic waste gas inlet 2 through the heating plate 16. When passing through the heating plate 16, the organic waste gas is heated by the heating plate 16, and some toxic gases are heated and decomposed. The organic waste gas that releases toxic gases after being heated can be adsorbed by the adsorption plate 17, and then discharged through the organic waste gas inlet 2.
