Description

Technical Field

[0001] This utility model relates to the field of sodium hypochlorite technology, and in particular to a sodium hypochlorite production equipment. Background Technology

[0002] Sodium hypochlorite is a common chemical substance, usually found in aqueous solution, and widely used for disinfection and bleaching. It is a product of the reaction between chlorine gas and sodium hydroxide. Sodium hypochlorite has strong oxidizing properties and can effectively kill bacteria, viruses, and fungi, therefore it is commonly used for drinking water disinfection, swimming pool water treatment, and the cleaning and disinfection of medical devices. In addition, it is widely used in household cleaning, laundry bleaching, and some industrial fields such as pulp bleaching and textile dyeing.

[0003] Sodium hypochlorite is a commonly used disinfectant and bleaching agent with wide applications in industrial production. Currently, sodium hypochlorite is typically produced by reacting chlorine gas with a sodium hydroxide solution. However, in existing production equipment, the uneven mixing within the sodium hydroxide solution after chlorine gas is introduced results in insufficient contact between the chlorine gas and the sodium hydroxide solution, leading to a slow reaction rate and low absorption rate. This, in turn, affects the production efficiency and quality of sodium hypochlorite. Utility Model Content

[0020] 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.

[0021] Reference Figure 1-4A sodium hypochlorite production device includes a reaction vessel 1. The reaction vessel 1 is equipped with a stirring mechanism to agitate the sodium hydroxide solution through which chlorine gas is introduced, thus facilitating sodium hypochlorite production. A striking mechanism is located on the side of the reaction vessel 1 to promote contact between the chlorine gas and the sodium hydroxide solution during the stirring operation, thereby increasing the absorption rate and reducing chlorine residue in the tail gas. The stirring mechanism includes a rotating pipe 33 rotatably connected to the reaction vessel 1. A housing 34 is fixedly installed at the bottom end of the rotating pipe 33, serving to support the installation of a nozzle 38. The nozzle 38 is located at the bottom end of the housing 34 and is used to introduce chlorine gas into the sodium hydroxide solution. In the reactor, a stirring rod 35 is fixedly installed on the rotating tube 33. The stirring rod 35 is used to stir and mix chlorine gas and sodium hydroxide solution, thereby facilitating the production of sodium hypochlorite. The top end of the rotating tube 33 penetrates the top end of the reactor 1. The rotating tube 33 is used to support the installation of the stirring rod 35. A toothed ring 32 is provided on the surface of the rotating tube 33. The toothed ring 32 is used to mesh with a gear 37. A motor 36 is fixedly installed at the top end of the reactor 1. The motor 36 is used to drive the gear 37 to rotate. The gear 37 is fixedly installed on the shaft end of the motor 36. The gear 37 meshes with the toothed ring 32. By setting up the gear 37 and the toothed ring 32, the rotating tube 33 is driven to rotate when the motor 36 is working.

[0022] The striking mechanism includes a vertical plate 27, which is fixedly installed at the top of the reactor 1. The vertical plate 27 is designed to support the sliding of the slide rod 24. The slide rod 24 is slidably mounted on the vertical plate 27. The slide rod 24 is square in shape and is used to support the installation of the mounting plate 21. It also serves to limit the movement of the mounting plate 21. The mounting plate 21 is fixedly mounted on one end of the slide rod 24. The mounting plate 21 is designed to support the installation of the striking rod 22. The striking rod 22 is mounted on the mounting plate 21 and is used to strike the reactor 1. The other end of the slide rod 24 is equipped with a roller 26, which is used to roll on the eccentric wheel 23.

[0023] In detail, the rotating tube 33 is cylindrical in shape and connects to the box body 34. The rotating tube 33 is designed to support the installation of the stirring rod 35.

[0024] Furthermore, a gas supply pipe 31 is rotatably connected to the inner wall of the rotating pipe 33. The gas supply pipe 31 is used to input chlorine gas into the rotating pipe 33. The stirring rod 35 is cylindrical in shape and is used to stir and mix chlorine gas and sodium hydroxide solution, thereby facilitating the production of sodium hypochlorite.

[0025] Furthermore, a spring 25 is fixedly installed on the side of the vertical plate 27. One end of the spring 25 is fixedly connected to the mounting plate 21. The spring 25 is designed to apply force to the slide bar 24 on the side of the mounting plate 21, so that the roller 26 at one end of the slide bar 24 is tightly attached to the eccentric wheel 23.

[0026] More specifically, an eccentric wheel 23 is fixedly installed on the gear 37, and the roller 26 rolls on the eccentric wheel 23. The eccentric wheel 23, in conjunction with the roller 26, is used to drive the slide bar 24 to move back and forth in a straight line along the through hole between it and the vertical plate 27. This facilitates the repeated striking of the reactor 1 by the striking rod 22 driven by the mounting plate 21, which promotes the contact between chlorine gas and sodium hydroxide solution, improves the absorption rate, and reduces chlorine residue in the tail gas.

[0027] In general, the vertical plate 27 is square in shape and is used to support the sliding of the slide bar 24. The mounting plate 21 is square in shape and is used to support the installation of the striking bar 22.

[0028] Finally, the reactor 1 is equipped with a feed pipe at the top and a discharge pipe at the bottom. The feed pipe and discharge pipe facilitate the feeding and discharging of materials.

[0029] Operating Procedure: During operation, sodium hydroxide solution is fed into reactor 1 through the feed pipe, and then chlorine gas is introduced into the rotary tube 33 through the gas supply pipe 31. The motor 36 is then started, driving gear 37 to rotate. Gear 37 meshes with gear ring 32, causing gear ring 32 to rotate. As gear ring 32 rotates, it drives rotary tube 33 to rotate. Rotation of rotary tube 33, through housing 34, causes nozzle 38 to rotate in a circular motion. Chlorine gas enters housing 34 through rotary tube 33 and then enters the sodium hydroxide solution through nozzle 38, facilitating mixing of chlorine gas and sodium hydroxide solution. Simultaneously, the rotation of rotary tube 33... At the same time, the rotating gear 37 will also drive the stirring rod 35 to rotate, further improving the mixing effect of chlorine gas and sodium hydroxide solution. Simultaneously, when the gear 37 rotates, it will also drive the eccentric wheel 23 to rotate. Due to the setting of the spring 25, the roller 26 is in close contact with the eccentric wheel 23. Therefore, when the eccentric wheel 23 rotates, it will drive the slide rod 24 to move back and forth in a straight line along the through hole between the slide rod 24 and the vertical plate 27 through the roller 26. When the slide rod 24 moves back and forth in a straight line, it will drive the striking rod 22 to repeatedly strike the reaction vessel 1 through the mounting plate 21. Through the above settings, the purpose of promoting the contact between chlorine gas and sodium hydroxide solution is achieved, thereby improving the absorption rate.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
