[0002] At present, hydrochloric acid, as the aqueous solution of hydrogen chloride, is an important monobasic inorganic strong acid, and has wide application in the industrial field, and the colorless transparent liquid form is accompanied by strong pungent smell and high corrosiveness, so that special attention and caution are needed in the production, storage and use process. Especially concentrated hydrochloric acid, because of its strong volatility, once the container is opened, hydrogen chloride gas will volatilize rapidly and combine with water vapor in the air to form small droplets of hydrochloric acid, thereby forming acid mist above the bottle mouth.

[0003] Among them, in the production process of hydrochloric acid, the use of cooling device is an essential link, and the production of hydrochloric acid is often accompanied by high temperature and chemical reaction. The heat generated in these processes needs to be dissipated in time to ensure the stable progress of the production process and the product quality. The role of the cooling device is to maintain the suitable temperature of the production environment by effectively absorbing and removing the heat.

[0004] And when cooling hydrochloric acid in the market, it is difficult to continuously and efficiently cool hydrochloric acid, and the cooling liquid temperature is constantly increasing, which is not easy to cool quickly, thereby reducing the cooling efficiency of hydrochloric acid. Therefore, we propose a cooling device for hydrochloric acid production, which can continuously and efficiently cool hydrochloric acid. UTILITY MODEL CONTENT

[0026] Please see Figures 1-4 This utility model provides a technical solution: a cooling device for hydrochloric acid production, including a cooling tank 1, two sets of cooling tanks 1, a connecting pipe 11 connected to the top of each of the two sets of cooling tanks 1, a cooling cover 12 connected to the top of each of the two sets of connecting pipes 11, a detachable cover 13 installed on the top of the cooling cover 12, and a cooling mechanism installed on the inner side and bottom of the cooling cover 12.

[0027] The cooling mechanism includes a water guide cover 2 fixedly installed at the bottom of the cover 13, multiple sets of equally spaced water guide holes 21 opened at the bottom of the water guide cover 2, a drip tube 22 connected to the bottom of each set of water guide holes, cooling pipes 23 connected to both sides of the cooling cover 12, a cooling fan 24 that can be detachably installed inside the two sets of cooling pipes 23, and a circulation pipe 25 connected to the top of the cover 13. The bottom end of the circulation pipe 25 is connected to the water guide cover 2. The two sets of cooling fans 24 are respectively a blower fan and an exhaust fan.

[0028] By driving the circulation pump 34 on the bottom side of the cooling tank 1, the coolant inside the cooling tank 1 can be introduced into the water guide shroud 2 through the circulation pipe 25. With the help of multiple sets of equally spaced drip tubes 22 connected to the bottom side of the water guide shroud 2, the coolant inside the water guide shroud 2 can fall in the form of water columns. At the same time, the two sets of cooling fans 24 inside the two sets of cooling pipes 23 are turned on. The blowing fan introduces cold air from the outside, and the exhaust fan exhausts the hot air. This can efficiently cool the multiple sets of water column coolant, and further ensure that the coolant cools the hydrochloric acid inside the cooling copper pipe 32.

[0029] In this technical solution, a waterproof mesh 31 is fixedly installed inside the cooling cover 12. The outer wall of the waterproof mesh 31 is in contact with the inner wall of the two sets of cooling pipes 23. Dustproof mesh 3 can be detachably installed on the outer wall of the two sets of cooling pipes 23, which has a good dustproof effect.

[0030] When the operator drives the blower and exhaust fan simultaneously, the dustproof nets 3 installed at the ports of both cooling pipes 23 can effectively prevent external dust from entering the cooling cover 12. At the same time, the blower and exhaust fan will generate a strong airflow after being driven. The waterproof net 31 installed on the inner wall of the cooling cover 12 can effectively block the coolant from being discharged from the cooling pipes 23, thus preventing coolant loss.

[0031] In this technical solution, a circulation pump 34 is fixedly installed on the bottom side of both sets of cooling tanks 1. Both sets of circulation pumps 34 are connected to the circulation pipe 25 through conduits, which can guide the coolant inside the cooling tank 1 into the cooling cover 12.

[0032] When the temperature sensor 33 detects that the temperature of the coolant inside the cooling tank 1 has reached the set value, it will send a signal to the control processor to drive the circulation pump 34 to introduce the coolant inside the cooling tank 1 into the cooling cover 12 for cooling.

[0033] In this technical solution, cooling copper pipes 32 are fixedly installed inside both sets of cooling tanks 1. The two ends of the two sets of cooling copper pipes 32 pass through the top and bottom of both sides of the cooling tanks 1 respectively, which can cool the hydrochloric acid inside the cooling copper pipes 32. Temperature sensors 33 are fixedly installed on one side of the inner wall of both sets of cooling tanks 1, and electric valves are fixedly installed on both sets of connecting pipes 11, which can detect the temperature of the coolant inside the cooling tanks 1.

[0034] When the temperature sensor 33 detects that the temperature of the coolant inside the cooling tank 1 has reached the set value, it will send a signal to the control processor. This will not only drive the circulation pump 34 to cool the coolant, but also open the mutual electric valve to introduce the cooled coolant into the cooling tank 1. At the same time, high-temperature hydrochloric acid will also be introduced into another set of cooling copper pipes 32, so that the unused coolant in the cooling tank 1 will continue to cool the hydrochloric acid inside the cooling copper pipes 32.

[0035] In use, the produced hydrochloric acid solution is first introduced into one set of cooling copper pipes 32. Since the cooling copper pipes 32 are distributed inside the cooling tank 1 containing coolant, when the high-temperature hydrochloric acid continuously flows from the cooling copper pipes 32, the low-temperature coolant absorbs the heat of the hydrochloric acid and cools it. At the same time, it drives the circulation pump 34 on the bottom side of the cooling tank 1, which can guide the coolant inside the cooling tank 1 from the circulation pipe 25 into the water guide cover 2. With the help of multiple sets of equally spaced drip tubes 22 connected to the bottom side of the water guide cover 2, the coolant inside the water guide cover 2 falls in a water column shape. Simultaneously, the two sets of cooling fans 24 inside the two sets of cooling pipes 23 are turned on. The blowing fan introduces cold air from the outside, and the exhaust fan exhausts the hot air, which can efficiently cool the multiple sets of water column coolant, further ensuring that the coolant cools the hydrochloric acid inside the cooling copper pipes 32. At the same time, through the fixed installation inside the cooling cover 12... The cooling tank 12 is equipped with a waterproof mesh 31, and dustproof mesh 3 can be detachably installed on the outer walls of both sets of cooling pipes 23. When the operator drives the blower and exhaust fan simultaneously, the dustproof mesh 3 installed at the ports of both sets of cooling pipes 23 can effectively prevent external dust from entering the cooling shroud 12. At the same time, the blower and exhaust fan will generate a strong airflow after being driven. The waterproof mesh 31 installed on the inner wall of the cooling shroud 12 can effectively block the coolant from being discharged from the cooling pipes 23, thus preventing coolant loss. Finally, when the temperature sensor 33 detects that the coolant temperature inside the cooling tank 1 has reached the set value, it will send a signal to the control processor. This will not only drive the circulation pump 34 to cool the coolant, but also open the mutual electric valves to introduce the cooled coolant into the cooling tank 1. At the same time, high-temperature hydrochloric acid will also be introduced into another set of cooling copper pipes 32, so that the unused coolant in the cooling tank 1 will continue to cool the hydrochloric acid inside the cooling copper pipes 32.
