Description

Technical Field

[0001] This utility model relates to a brine electrolysis device, and more particularly to the structure of a brine electrolysis device for hydrochloric acid synthesis. Background Technology

[0002] Hydrochloric acid is an aqueous solution of hydrogen chloride. It is a colorless, transparent liquid with a strong, pungent odor and is highly corrosive. It is widely used in the dye, pharmaceutical, food, and metallurgical industries. Hydrochloric acid is primarily produced by electrolyzing brine to generate chlorine and hydrogen gas, which are then used to directly synthesize hydrochloric acid.

[0003] Existing brine electrolysis devices for hydrochloric acid synthesis generate impurities during the electrolysis process. With prolonged use of the electrode plates, bubbles, dirt, and impurities accumulate on their surfaces, affecting the electrolysis efficiency and effectiveness. Cleaning requires filling the equipment with a large amount of water until the water level exceeds the electrode plates before impurities can be removed, wasting a significant amount of water resources.

[0004] Moreover, in the existing brine electrolysis device for hydrochloric acid synthesis, the brine can only flow and be stirred horizontally when the rotating rod drives the stirring blades to rotate. The brine is not stirred sufficiently, resulting in uneven stirring of the brine above and below the stirring blades, which affects the electrolysis efficiency.

[0005] In addition, impurities are easily generated during the electrolysis process. In order to improve the electrolysis efficiency and save water resources, the electrolyzed brine is filtered out of impurities and reused. However, the existing filter structure is prone to clogging, requiring staff to manually clean the impurities from the filter structure. The cleaning process is very troublesome, time-consuming and labor-intensive, and affects normal production.

[0006] The purpose of this invention is to solve the problems of impurities easily adhering to the electrode plates of the brine electrolysis device for hydrochloric acid synthesis, uneven stirring of brine, and easy clogging of the filter structure, which affect the electrolysis efficiency.

A cathode plate 15 and an anode plate 16 are disposed inside the tank 1. The cathode plate 15 and the anode plate 16 are arranged opposite each other on the inner wall of the tank 1. The stirring device 2 includes a stirring motor 21, a stirring shaft 22, and stirring blades 23.

A drive wheel 58 is provided on the output shaft of the cleaning motor 54. The drive wheel 58 and the driven wheel 57 are connected by a transmission belt 52.

[0060] When there are many impurities on the filter plate 42, the cleaning motor 54 drives the cleaning plate 53 to rotate, so that the cleaning plate 53 scrapes along the outer side of the filter plate 42, and sweeps the impurities adhering to the filter plate 42 to the drain outlet for discharge, so as to prevent the impurities from affecting the filtration effect and filtration efficiency of the filter plate 42.

[0061] The rinsing device 6 includes a vertical pole 61, a support rod 62, and a water pump 63.

The water pump 63 is turned on and sprays the filter plate 42 thoroughly through the nozzles 65 on the spray pipe 64, thereby washing away the impurities in the filter holes and improving the filtration efficiency.

[0063] In use, brine is added to tank 1 through inlet 11. Power is then switched on, and electrolysis of the brine begins through cathode 15 and anode 16, producing hydrogen and chlorine. A certain proportion of nitrogen is continuously added to tank 1 through gas inlet 19, causing the nitrogen to mix with the hydrogen and chlorine to form a mixed gas.

Simultaneously, the scraping plate 33 on the scraping device 3 scrapes away impurities generated on the electrode plates.

[0064] When there are many impurities on the filter plate 42, the cleaning motor 54 is turned on, which drives the cleaning plate 53 to rotate, causing the cleaning plate 53 to scrape along the outer side of the filter plate 42, sweeping the impurities adhering to the filter plate 42 to the drain outlet for discharge.

When impurities are generated on the cathode plate 15 and the anode plate 16, the cleaning motor 54 drives the scraping plates 33 on the scraping device 3 to scrape the impurities generated on the electrode plates, thereby removing the impurities generated on the electrode plates, thereby improving the electrolysis efficiency and solving the problem that the electrolysis efficiency is affected by the adhering impurities on the electrode plates of the existing brine electrolysis device.

[0066] A cleaning device 5 is installed. When there are many impurities on the filter plate 42, the cleaning motor 54 drives the cleaning plate 53 to rotate, so that the cleaning plate 53 scrapes along the outer side of the filter plate 42 to remove the impurities adhering to the filter plate 42, preventing the impurities from affecting the filtration effect and filtration efficiency of the filter plate 42.

[0067] A rinsing device 6 is installed, and the upright 61 is fixedly connected to the connecting plate 56.
