Description

Technical Field

[0001] This utility model relates to the technical field of exhaust gas treatment devices, and in particular to an exhaust gas treatment device for disinfectant production. Background Technology

[0002] With increasing global awareness of public health and increasingly stringent requirements for hygiene, the production scale of disinfectants continues to expand. The production process of disinfectants generates a large amount of complex exhaust gases. Common disinfectant production processes, such as the preparation of chlorine-containing disinfectants, release harmful gases such as chlorine and hydrogen chloride.

[0003] Traditional exhaust gas treatment devices have revealed many shortcomings when dealing with exhaust gases from disinfectant production. Most traditional devices only use a single treatment process, such as simple water washing. Although this can remove some water-soluble hydrogen chloride gas, the water washing method does not perform acid-base adjustment when recycling the sprayed water. As a result, the water used in subsequent recycling will be acidic, which will reduce the treatment effect on the exhaust gas. Utility Model Content

[0023] In the specific design,

[0024] The spray treatment assembly includes multiple sets of eighth pipes 15 fixedly connected inside the first treatment box 1 and nozzles 16 fixedly connected to the bottom of the eighth pipes 15. A seventh pipe 14 is fixedly connected to the outside of the eighth pipes 15. A filter screen 17 is also fixedly connected inside the first treatment box 1. The nozzles 16 are used to spray atomized water to react with the exhaust gas.

[0025] In a further design, an air inlet pipe 2 is fixedly connected to the outside of the first processing box 1, and a reaction assembly is provided inside the second processing box 3;

[0026] The reaction assembly includes a three-dimensional mesh plate 18 fixedly connected within the second treatment chamber 3, with a catalyst loaded on its surface. An electric heating rod 20 is also fixedly connected within the second treatment chamber 3. The catalyst is a precious metal catalyst, such as platinum (Pt) or palladium (Pd). After the exhaust gas is washed with water, the electric heating rod 20 heats it to a suitable reaction temperature, typically 250-350℃. Under the suitable temperature and with the action of the catalyst, the hydrocarbons in the organic waste gas undergo a catalytic oxidation reaction with oxygen, producing harmless carbon dioxide and water.

[0027] In a further design, an adsorption assembly is provided in the third treatment box 5. The adsorption assembly is an activated carbon adsorption plate 19 fixedly connected in the third treatment box 5. A first pipe 4 is fixedly connected between the first treatment box 1 and the second treatment box. A second pipe 6 is fixedly connected between the second treatment box 3 and the third treatment box 5. A reflux mechanism is provided outside the first treatment box 1. An acid-base adjustment assembly is provided in the reflux mechanism.

[0028] The reflux mechanism includes a third pipe 7 fixedly connected to the bottom of the first treatment tank 1, a filter box 8 fixedly connected to the outside of the third pipe 7, a mixing box 9 fixedly connected to the output end of the filter box 8, and a water pump 11 installed outside the mixing box 9. The input end of the water pump 11 is fixedly connected to a fourth pipe 10, which is fixedly connected to the inside of the mixing box 9. The output end of the water pump 11 is fixedly connected to a fifth pipe 12, one end of which is fixedly connected to a seventh pipe 14. Through the water pump 11, the water accumulated at the bottom of the first treatment tank 1 can be pumped into the mixing box 9. An alkaline solution, such as sodium hydroxide, can be added into the mixing box 9 through the storage cylinder 22, thereby adjusting the water to acid and alkali. The adjusted water is then transported again through the cooperation of the fifth pipe 12 and the seventh pipe 14 and sprayed out through the nozzle 16, which saves water resources and ensures the stability of the treatment effect.

[0029] The acid-base mixing component includes a fixed frame 21 fixedly connected to the top of the mixing tank 9 and a storage cylinder 22 fixedly connected to the outside of the fixed frame 21. An electric valve is fixedly connected to the bottom output end of the storage cylinder 22. The electric valve can be controlled by a controller to open and close at regular intervals, thereby releasing the alkaline solution in the storage cylinder 22 at regular intervals.

[0030] To accelerate the reaction between the alkaline solution and the aqueous solution, a motor 23 is fixedly connected to the outside of the mixing tank 9, and a stirring rod 24 is rotatably connected inside the mixing tank 9. The motor 23 is fixedly connected to the stirring rod 24, and the motor 23 is used to drive the stirring rod 24 to rotate, thereby accelerating the reaction between the alkaline solution and the aqueous solution.

[0031] As another embodiment, a sixth pipe 13 is fixedly connected to the outside of the fifth pipe 12. The sixth pipe 13 is connected to an external water pipe for outputting new water into the nozzle 16 for spraying.

[0032] The method of using this utility model is as follows:

[0033] The exhaust gas is transported to the first treatment tank 1 through the intake pipe 2. After the water sprayed by the nozzle 16 comes into contact with the exhaust gas, it can efficiently remove most of the water-soluble pollutants in the exhaust gas, such as hydrogen chloride. The water pump 11 can pump the water accumulated at the bottom of the first treatment tank 1 to the mixing tank 9. An alkaline solution, such as sodium hydroxide, can be added to the mixing tank 9 through the storage cylinder 22, so as to adjust the acid and alkali of the water. The adjusted water is then transported again through the fifth pipe 12 and the seventh pipe 14 and sprayed out through the nozzle 16, which saves water resources and ensures the stability of the treatment effect.

[0034] The exhaust gas treated by the first treatment box 1 enters the second treatment box 3, and after being heated by the electric heating rod 20, it is generally 250-350℃. Under the action of temperature and catalyst, the hydrocarbons in the organic waste gas undergo catalytic oxidation reaction with oxygen to produce harmless carbon dioxide and water.

[0035] After being treated by the second treatment box 3, the exhaust gas enters the third treatment box 5, where it is adsorbed by the activated carbon adsorption plate 19 before being discharged.
