Description

Technical Field

[0001] This utility model relates to the field of treatment device technology, specifically a heparin sodium extraction waste gas treatment device. Background Technology

[0002] Sodium heparin, an important anticoagulant, is mostly extracted from animal tissues such as the small intestinal mucosa of pigs. Its production process involves multiple steps, including raw material processing, enzymatic hydrolysis, adsorption, and elution. During the process, it is easy to generate malodorous gases containing ammonia and hydrogen sulfide. In order to reduce environmental pollution, the waste gas needs to be treated. For example, the authorized patent with announcement number CN210786775U (a waste gas deodorization device for the production of crude heparin sodium) includes a shell, an odorization mechanism installed inside the shell, a rotating mechanism installed on the left side of the odorization mechanism, a pipe fixed to the top left side of the shell, an opening and closing mechanism installed on the top of the pipe, and a bracket fixed to the top right end of the shell. While the aforementioned existing technologies have accelerated deodorization and shortened working time, they rely solely on activated carbon adsorption for deodorization, resulting in unstable deodorization in heparin sodium exhaust gas treatment and poor practicality. Therefore, there is an urgent market need to develop a heparin sodium extraction exhaust gas treatment device to help people solve the existing problems. Utility Model Content

[0003] The purpose of this invention is to provide a heparin sodium extraction waste gas treatment device to solve the problems mentioned in the background art, such as the inability to stably deodorize and poor practicality in the treatment of heparin sodium waste gas.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heparin sodium extraction waste gas treatment device, comprising an input pipe, a spray box fixedly installed on one side of the input pipe, a decomposition box fixedly installed above one side of the spray box, an adsorption box fixedly installed on one side of the decomposition box, a liquid distribution box fixedly installed above the spray box, the lower end of the liquid distribution box extending into the interior of the spray box, an atomizing nozzle fixedly installed below the liquid distribution box, a UV lamp fixedly installed above the interior of the decomposition box, and an activated carbon adsorption plate disposed inside the adsorption box.

[0005] Preferably, one end of the decomposition box is provided with a through hole one, and the decomposition box is connected to the spray box through the through hole one. The other end of the decomposition box is provided with a through hole two, and the decomposition box is connected to the adsorption box through the through hole two. A demister is fixedly installed inside the spray box along one side of the through hole one.

[0006] Preferably, multiple activated carbon adsorption plates are provided, and the multiple activated carbon adsorption plates are arranged at intervals in a vertical direction. Support strips are movably provided at the front and rear ends below the activated carbon adsorption plates, and the support strips are fixedly connected to the adsorption box.

[0007] Preferably, a lid is fixedly installed on one side of the adsorption box by screws, and a sealing gasket is fixedly installed on the inside of the lid.

[0008] Preferably, an alkaline solution pipe is fixedly installed at the rear end of the liquid distribution box, and a drain pipe is fixedly installed below the rear end of the spray box.

[0009] Preferably, a fan box is fixedly installed below the rear end of the adsorption box, the adsorption box is connected to the fan box, a fan is fixedly installed inside the fan box, and an output pipe is fixedly installed at the rear end of the fan box.

[0010] Preferably, a support plate one is fixedly installed below the spray box, a support plate two is fixedly installed below the adsorption box, and a base plate is fixedly installed below the support plate one.

[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model sets up a spray box, a decomposition box and an adsorption box. The atomized spray of alkaline solution in the spray box can efficiently neutralize the acidic and easily soluble odor components in the exhaust gas. The UV lamp in the decomposition box can decompose malodorous organic matter, destroy the molecular structure and reduce the odor load. The activated carbon adsorption plate in the adsorption box purifies the air and ensures that the residual odor substances are removed. In this way, the deodorization efficiency and stability are greatly improved through the composite process, and the practicality and reliability of the device are enhanced.

[0012] (2) By setting up a demister, this utility model can effectively remove droplets and mist generated during the spraying stage, prevent alkaline solutions from being carried to the decomposition box, protect the UV lamp from moisture or contamination, extend its service life and maintain photolysis efficiency, and increase its practicality.

[0013] (3) By setting up multiple vertically spaced activated carbon adsorption plates, this utility model increases the adsorption area and waste gas contact time, improves the adsorption capacity and purification effect, and is conducive to the stable treatment of the odor of heparin sodium extraction waste gas.

[0016] 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.

[0017] Please see Figure 1-4 This utility model provides an embodiment of a heparin sodium extraction waste gas treatment device, including an input pipe 1, which is externally connected to the waste gas output pipe of the heparin sodium extraction equipment. A spray box 2 is fixedly installed on one side of the input pipe 1. A decomposition box 3 is fixedly installed above one side of the spray box 2. An adsorption box 4 is fixedly installed on one side of the decomposition box 3. A liquid distribution box 7 is fixedly installed above the spray box 2 for distributing alkaline solution. The lower end of the liquid distribution box 7 extends into the interior of the spray box 2. An atomizing nozzle 14 is fixedly installed below the liquid distribution box 7. A UV lamp 17 is fixedly installed above the interior of the decomposition box 3. An activated carbon adsorption plate 19 is provided inside the adsorption box 4.

[0018] After the waste gas is introduced through the input pipe 1, it first passes through the spray box 2, where an alkaline solution is distributed by the liquid distribution box 7 and sprayed through the atomizing nozzle 14 for preliminary treatment. Then it enters the decomposition box 3, where harmful substances in the waste gas are decomposed by the UV lamp 17. Finally, it enters the adsorption box 4, where activated carbon adsorption plates 19 further adsorb and purify the waste gas. This multi-stage synergistic treatment method can effectively improve the treatment effect of heparin sodium waste gas, achieve stable deodorization, and enhance the practicality of the device.

[0019] Please see Figure 3 One end of the decomposition box 3 is provided with a through hole 16, through which the decomposition box 3 is connected to the spray box 2. The other end of the decomposition box 3 is provided with a through hole 18, through which the decomposition box 3 is connected to the adsorption box 4. A demister 15 is fixedly installed inside the spray box 2 along one side of the through hole 16.

[0020] The design of through-hole 16 and through-hole 2 18 allows the exhaust gas to pass through the spraying, decomposition and adsorption treatment stages in sequence, ensuring the continuity and orderliness of the treatment process. At the same time, the demister 15 can effectively remove the mist droplets carried by the exhaust gas after spraying treatment, increasing its practicality.

[0021] Please see Figure 3 and Figure 4 Multiple activated carbon adsorption plates 19 are provided, and the multiple activated carbon adsorption plates 19 are arranged vertically at intervals. Support strips 20 are movably provided at the front and rear ends below the activated carbon adsorption plates 19, and the support strips 20 are fixedly connected to the adsorption box 4.

[0022] The multi-layer activated carbon adsorption plate 19 can more thoroughly adsorb odors and harmful substances in the exhaust gas, thereby significantly improving the adsorption and purification effect.

[0023] Please see Figure 3 and Figure 4 A cover 10 is fixedly installed on one side of the adsorption box 4 by screws, and a sealing gasket 21 is fixedly installed on the inside of the cover 10.

[0024] The cover 10 provides a convenient access point for inspection, maintenance, and replacement of activated carbon adsorption plates inside the adsorption box. The sealing gasket 21 can fit tightly against the opening edge of the adsorption box 4, effectively preventing waste gas from leaking out from the connection between the cover and the adsorption box during the treatment process.

[0025] Please see Figure 2 An alkaline solution pipe 8 is fixedly installed at the rear end of the liquid distribution box 7. The alkaline solution pipe 8 is connected to an alkaline solution supply device. A drain pipe 9 is fixedly installed at the lower rear end of the spray box 2.

[0026] During the waste gas treatment process, the alkaline solution pipe 8 can deliver alkaline solution to the liquid distribution box 7, ensuring that the atomizing nozzles 14 in the spray box 2 can spray alkaline solution normally to perform preliminary treatment of the waste gas, while the drain pipe 9 is used to discharge the waste liquid generated after the spray treatment in a timely manner.

[0027] Please see Figure 2 A fan box 5 is fixedly installed at the lower rear end of the adsorption box 4. The adsorption box 4 and the fan box 5 are connected. A fan is fixedly installed inside the fan box 5. An output pipe 6 is fixedly installed at the rear end of the fan box 5.

[0028] When the fan is running, it can generate negative pressure, which causes the exhaust gas to pass through the spray box 2, the decomposition box 3 and the adsorption box 4 in sequence from the input pipe 1 for treatment, ensuring the smooth flow of exhaust gas in the device.

[0029] Please see Figure 1 A support plate 12 is fixedly installed below the spray box 2, a support plate 2 13 is fixedly installed below the adsorption box 4, and a base plate 11 is fixedly installed below the support plate 12.

[0030] The installation of support plate 12, support plate 2 13 and base plate 11 provides stable support for the spray box and adsorption box, increasing the stability of the device.

[0031] Working principle: During use, the exhaust gas enters through the inlet pipe 1 and first reaches the spray box 2. The alkaline solution pipe 8 delivers alkaline solution to the liquid distribution box 7, which is then evenly sprayed through the atomizing nozzle 14, making full contact with the exhaust gas for preliminary treatment. The demister 15 in the spray box 2 removes the mist droplets carried by the exhaust gas. Afterward, the exhaust gas enters the decomposition box 3 through the first through-hole 16. The UV lamp 17 decomposes the harmful substances in the exhaust gas. The decomposed exhaust gas then enters the adsorption box 4 through the second through-hole 18. Multiple activated carbon adsorption plates 19 arranged vertically at intervals in the adsorption box 4 further adsorb and purify the exhaust gas, which can more thoroughly remove odors and harmful substances. The box cover 10 fixed to one side of the adsorption box 4 with screws facilitates internal maintenance and replacement of activated carbon adsorption plates. The treated exhaust gas is discharged through the outlet pipe 6, which increases its practicality.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
