Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, in particular to a purification treatment device for boiling point organic compound waste gas. Background Technique

[0002] Volatile organic compounds refer to organic compounds with a saturated vapor pressure greater than 70 Pa at normal temperature and a boiling point below 260 °C under normal pressure, or all organic compounds with a vapor pressure greater than or equal to 10 Pa and volatility at 20 °C. With the increasing amount of organic compounds entering the atmosphere along with production waste gas, such as benzene, alcohols, polycyclic aromatic hydrocarbons, aldehydes, ketones, etc., these substances not only have a stimulating effect on the human senses, but also many substances have certain toxicity, which will not only pollute the environment, but also seriously damage people's health. Therefore, the control of such pollutants has been increasingly emphasized by people.

[0003] In the patent document with the publication number of CN220214431U, a waste gas treatment device for organic compounds is disclosed. Before the waste gas treatment device is put into operation, the cover plate can be opened, and activated carbon can be added into the adding pipe. The filter screen plate can increase the contact area between the waste gas and the activated carbon, and the design of multiple adding plates further increases the contact area between the activated carbon and the waste gas. This design can increase the adsorption reaction efficiency. In the process of implementing this technical solution, the inventor found that there are at least the following problems in the prior art:

[0004] When the above device is actually used, the organic matter in the waste gas is adsorbed and treated by activated carbon, and then the pollutants in the waste gas are oxidized and decomposed by a CO furnace. However, the pretreatment of components such as particulate matter and oil mist contained in the waste gas is lacking, which will seriously affect the service life and purification effect of the activated carbon. Although it is convenient to replace the activated carbon, during the process of treating waste gas, the activated carbon is easily saturated by adsorption, and frequent replacement will cause an increase in use cost and waste of resources, and the use effect is not good. Content of the Utility Model

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] In this boiling point organic waste gas purification and treatment device, the water sprayed by the atomizing nozzles forms water mist to preliminarily filter the odor and particulate matters in the waste gas in the spray cavity. The filter plate filters the water vapor and oil mist in the waste gas, pre-treating the waste gas before the activated carbon adsorption, and avoiding the influence of components such as particulate matters and oil mist in the waste gas on the adsorption effect of the activated carbon.

[0025] Please refer to Figures 1-3 , a boiling point organic waste gas purification treatment device, including an adsorption box 1.

[0026] In the specific implementation process, as Figure 1 , Figure 2 and Figure 3 shown, one side of the adsorption box 1 is communicated with a first pipeline 2, one end of the first pipeline 2 is provided with a filtering component 3, the other side of the adsorption box 1 is communicated with a second pipeline 4, one end of the second pipeline 4 is communicated with a CO furnace 5, one side of the filtering component 3 is provided with an air inlet pipe 6, one side of the CO furnace 5 is provided with an exhaust pipe 7, the top of the exhaust pipe 7 is communicated with a third pipeline 8, an electric control valve 9 is arranged on the third pipeline 8, and one end of the third pipeline 8 is communicated with the top of the adsorption box 1.

[0027] The filtering component 3 includes a filtering tank 31 arranged at the bottom end of the first pipeline 2, a partition plate 32 is fixedly connected to the inner wall of the filtering tank 31, the top of the filtering tank 31 is communicated with a water delivery pipe 33, one end of the water delivery pipe 33 is communicated with a spray pipe 34, a plurality of atomizing nozzles are arranged at the bottom of the spray pipe 34, a filter plate 35 is fixedly installed on the inner wall of the filtering tank 31, and one side of the filtering tank 31 is communicated with a drain pipe 36.

[0028] It should be noted that: the waste gas enters the filter tank 31 through the intake pipe 6. The partition plate 32 divides the interior of the filter tank 31 into a spray chamber and a filter chamber. The water delivery pipe 33 delivers water to the spray pipe 34, and the water is sprayed out through the atomizing nozzles at the bottom of the spray pipe 34. The sprayed water forms a water mist to preliminarily filter the odor and particulate matter in the waste gas in the spray chamber. Then, the waste gas enters the filter chamber through the ventilation holes in the middle of the partition plate 32, and the water vapor and oil mist in the waste gas are filtered by two filter plates 35 to pre-treat the waste gas before activated carbon adsorption, avoiding the influence of components such as particulate matter and oil mist in the waste gas on the adsorption effect of the activated carbon. The waste water in the spray chamber can be discharged through the drain pipe 36. The pre-treated waste gas enters the adsorption box 1 through the first pipe 2, and the organic components in the waste gas are adsorbed and filtered by the activated carbon in the adsorption box 1, and then enter the CO furnace 5 through the second pipe 4 for high-temperature combustion to decompose the pollutants in the waste gas by combustion. The purified air is discharged into the outside through the discharge pipe 7. By opening the electric control valve 9, a part of the high-temperature gas in the discharge pipe 7 enters the adsorption box 1 through the third pipe 8. The high-temperature gas can desorb and regenerate the activated carbon after adsorbing the waste gas, not only making the activated carbon reusable, but also utilizing the waste heat of the high-temperature waste gas, achieving the pre-treatment of the waste gas before adsorption by the activated carbon, improving the purification effect of the activated carbon, saving the use cost, and improving the resource utilization rate.

[0029] A motor 10 is fixedly connected to the bottom inside the adsorption box 1. The output end of the motor 10 is fixedly connected to a lead screw 11. A lifting plate 12 is screwed on the lead screw 11. The motor 10 is bolted to the bottom inside the adsorption box 1. By starting the motor 10 through an external controller, the motor 10 drives the lead screw 11 to rotate, realizing the lifting effect of the lifting plate 12.

[0030] Three placing mesh cylinders 13 are bolted to the top of the lifting plate 12. Activated carbon is added into the placing mesh cylinders 13. The placing mesh cylinders 13 are bolted to the top of the lifting plate 12 for storing the activated carbon. The rising of the lifting plate 12 facilitates the addition and replacement of the activated carbon.

[0031] A sealing door 14 is rotatably arranged on the top of the adsorption box 1. A support rod 15 is inserted into one side of the lifting plate 12. By opening the sealing door 14, the placing mesh cylinder 13 rises above the adsorption box 1, and the support rod 15 guides and limits the lifting plate 12 to improve the stability of the lifting plate 12 and the placing mesh cylinder 13 during movement.

[0032] A water pump 16 is arranged on one side of the filter tank 31. One end of the water pump 16 is connected to a water tank 17 through a water suction pipe, and the water discharge end of the water pump 16 is connected to one end of the water delivery pipe 33. The water pump 16 pumps the water source in the water tank 17 into and conveys it to the water delivery pipe 33 to supply water to the spray pipe 34.

[0033] The working principle of the boiling point organic waste gas purification and treatment device provided by the present utility model is as follows:

[0034] During use, the waste gas enters the filtering tank 31 through the intake pipe 6. The water sprayed by the atomizing nozzle forms a water mist to preliminarily filter the odor and particulate matter in the waste gas in the spraying cavity. Then, the water vapor and oil mist in the waste gas are filtered through the filter plate 35 to pre-treat the waste gas before activated carbon adsorption, avoiding the influence of components such as particulate matter and oil mist in the waste gas on the adsorption effect of the activated carbon. The pre-treated waste gas enters the adsorption box 1 through the first pipe 2, and the organic components in the waste gas are adsorbed and filtered by the activated carbon in the adsorption box 1. Then, it enters the CO furnace 5 through the second pipe 4 for high-temperature combustion to burn and decompose the pollutants in the waste gas. The electric control valve 9 is opened to enable a part of the high-temperature gas in the discharge pipe 7 to enter the adsorption box 1 through the third pipe 8. The high-temperature gas can desorb and regenerate the activated carbon after adsorbing the waste gas, not only enabling the activated carbon to be reused, but also utilizing the waste heat of the high-temperature waste gas, achieving the pre-treatment of the waste gas before adsorption by the activated carbon, improving the purification effect of the activated carbon, saving the use cost, and improving the resource utilization rate.

[0035] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
