Technical Field

[0002] Chemical raw materials refer to the basic raw materials used in the chemical industry to synthesize various chemical products. They can be natural or artificial, and usually exist as the basic substances for chemical reactions. They are used to manufacture various chemical products such as fertilizers, plastics, pharmaceuticals, coatings, and daily chemical products. In the process of chemical production, harmful organic waste gases may be generated due to the processing of raw materials, chemical reactions, and the use of solvents. If these waste gases are discharged directly without treatment, they will harm the environment and human health. Therefore, it is necessary to purify and treat organic waste gases.
[0003] For example, a Chinese patent discloses an organic waste gas purification device for chemical raw material production (authorization announcement number CN219713385U). This patented technology solves the problem that existing waste gas treatment devices mainly rely on spraying and purification mechanisms to treat waste gas, which cannot reasonably recycle and reuse organic waste gas, resulting in excessive energy waste. It improves the resource recycling rate of organic waste gas and at the same time improves the purification effect of organic waste gas.
[0004] However, most existing methods for purifying organic waste gas from chemical raw materials involve combustion or immersion in acid or alkali solutions. The high temperature of the waste gas after combustion can interfere with the proper use of acid or alkali solutions and negatively impact purification efficiency. For example, the aforementioned prior art uses combustion to purify the organic waste gas. Therefore, those skilled in the art have provided an organic waste gas purification device for chemical raw material production processes to address the problems mentioned in the background section.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 This utility model provides a technical solution for an organic waste gas purification device in the production process of chemical raw materials: It includes a spray purification box 1, a condenser box 2 installed on one side of the spray purification box 1, an air inlet pipe 21 on one side of the condenser box 2, a condenser pipe 23 inside the condenser box 2, an air outlet pipe 22 penetrating through the upper surface of the condenser box 2, a first partition 11 at the middle position inside the spray purification box 1, a second partition 12 installed at the inner end of the spray purification box 1, a liquid pump 3 installed on the upper surface of the spray purification box 1, a second connecting pipe 32 and a first connecting pipe 31 arranged from left to right on the front surface of the spray purification box 1, a third connecting pipe 33 connected to the outlet end of the liquid pump 3, and a lower... The end is connected to a spray pipe 34. An adsorption box 4 is installed on one side of the condensation box 2. The adsorption box 4 is equipped with two sets of adsorption plates 53. A sealing plate 5 is installed on the upper surface of the adsorption box 4 by bolts. Two sets of baffles 52 are installed on the lower surface of the sealing plate 5. An exhaust pipe 41 is installed on one side of the adsorption box 4. This configuration uses the air inlet pipe 21 to allow organic waste gas to be introduced into the condensation pipe 23 inside the condensation box 2 for condensation. After condensation, it enters the spray purification box 1 through the air outlet pipe 22. After entering, the organic waste gas is efficiently neutralized and purified by entering the acid and alkali solution and spraying. Finally, it enters the adsorption box 4 and is adsorbed by the two sets of adsorption plates 53. This can improve the purification effect of organic waste gas from chemical raw materials.
[0023] like Figure 2 As shown, one end of the condenser pipe 23 is connected to one end of the inlet pipe 21, and the other end of the condenser pipe 23 is connected to one end of the outlet pipe 22. This arrangement uses the condenser pipe 23 to connect the inlet pipe 21 and the outlet pipe 22. In this way, after the organic waste gas enters the condenser pipe 23 through the inlet pipe 21, it is condensed and then enters the spray purification box 1 through the outlet pipe 22 to achieve its spray purification.
[0024] like Figure 1As shown, the inlet end of the pump 3 is connected to one end of the first connecting pipe 31 and the second connecting pipe 32. One end of the first connecting pipe 31 and the second connecting pipe 32 is connected to the interior of the spray purification box 1. This arrangement allows the acid and alkali solutions inside the spray purification box 1 to be extracted using the first connecting pipe 31 and the second connecting pipe 32. Valves are provided on the outside of the first connecting pipe 31 and the second connecting pipe 32 to open and close them. The pump 3 can be configured with two sets to achieve simultaneous operation according to actual usage.
[0025] like Figure 4 As shown, one end of the exhaust pipe 22 extends into the interior of the spray purification box 1. A second partition 12 is connected through one side of the first partition 11. A through pipe 121 is provided through the outside of the second partition 12. This arrangement uses the first partition 11 to divide the space inside the spray purification box 1, while the second partition 12 can prevent acid and alkali solutions inside it from entering the adsorption box 4. The exhaust gas after spray purification can be introduced into the adsorption box 4 through the through pipe 121 to achieve the purpose of purification.
[0026] like Figure 3 As shown, a frame 531 is symmetrically arranged on the inner side of the adsorption box 4, and the adsorption plate 53 is slidably installed inside the frame 531. This arrangement allows the adsorption plate 53 to slide inside the frame 531, thus enabling quick installation and removal of the adsorption plate 53 for easy maintenance.
[0027] like Figure 3 and Figure 4 As shown, a sealing gasket 51 is also provided on the lower surface of the sealing plate 5. The height of the adsorption box 4 is higher than the height of the baffle 52. This arrangement can achieve the sealing between the sealing plate 5 and the adsorption box 4 by using the sealing gasket 51, and the flow rate of organic waste gas can be reduced by the baffle 52, thereby achieving better adsorption and purification. The adsorption plate 53 can be made of activated carbon material.
[0028] The working principle of this utility model is as follows: In use, the organic waste gas purification device in the chemical raw material production process of this utility model introduces the organic waste gas to be purified into the condenser pipe 23 inside the condenser box 2 through the inlet pipe 21. The condenser box 2 is filled with condensing water. This reduces the temperature of the waste gas as it enters the condenser pipe 23, causing the organic solvents and gases to condense into liquid, thus removing organic matter. It should be noted that a pipe for liquid discharge can be installed outside the condenser pipe 23. After condensation, the organic waste gas enters the spray purification box 1 through the outlet pipe 22 and connects with the first partition 11. Acidic liquid is contacted on one side for acid neutralization. When the gas rises, the acidic liquid is drawn by the pump 3 and sprayed out through the spray pipe 34 on the lower surface of the third connecting pipe 33 to achieve acid neutralization again. The neutralized waste gas will enter the other side of the first partition 11 through the fixed pipe 13 for alkaline neutralization. The same spraying method is used to improve its purification. After purification, the waste gas will enter the adsorption box 4 through the through pipe 121. After entering, the gas will be blocked by the baffle 52 to reduce the flow rate. This allows the waste gas to slowly pass through the adsorption plate 53 for adsorption. Finally, after purification, it will be discharged to the outside through the exhaust pipe 41.
[0029] All electrical components used in this invention are existing known electrical devices, all of which are connected to an external main controller and external power supply, and all of which can be purchased and used directly on the market. Their structure, circuit, and control principle are all existing known technologies. The appropriate model is selected according to actual use. Therefore, the structure, circuit, and control principle of the device are not described in detail here.
[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
