Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen peroxide purification, in particular to a purification distillation tower with a water cooling function. Background Art

[0002] Hydrogen peroxide is an aqueous solution of hydrogen peroxide, which is widely used. When the content is high, it is an explosive chemical. Depending on the user, it is often necessary to purify the relatively stable low-concentration hydrogen peroxide. Generally, a distillation tower is used for distillation, purification and impurity removal. However, during the distillation process, the decomposition rate of hydrogen peroxide will be accelerated due to heating, which may cause explosion under improper operation. In addition to condensing steam, traditional distillation towers lack corresponding cooling functions and cannot quickly cool down the hydrogen peroxide with improved purity, which poses a great safety hazard. Therefore, we propose a purification distillation tower with water cooling function to solve the above problems. Utility Model Content

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a purification distillation tower with water cooling function, comprising a distillation tower body and a cold water pool, a reaction barrel is arranged at the inner bottom of the distillation tower body, the outer wall of the reaction barrel is fitted with the inner wall of the distillation tower body, the distillation tower body and the cold water pool are fixedly connected, a hydraulic cylinder is fixedly installed at the inner bottom of the cold water pool, an adapter is fixedly connected to the upper end of the hydraulic cylinder, a connecting seat is rotatably connected to the middle of the lower end of the reaction barrel, the hydraulic cylinder is rotatably connected to the connecting seat through the adapter, a slave gear is fixedly sleeved on the outer side of the connecting seat, the right end of the slave gear is meshed with a main gear, the output end of the driving motor is fixedly plugged at the axis of the main gear, a stirring blade is rotatably installed at the middle of the interior of the reaction barrel, and the lower end of the stirring blade passes through the reaction barrel and is fixedly connected to the connecting seat.

[0006] Preferably, six groups of bonding plates arranged in a circular array are fixedly connected to the inner bottom of the cold water pool, and the inner walls of the bonding plates are in contact with the reaction barrel.

[0008] Preferably, the condenser is provided with a water delivery pipe near the inlet, and the condenser is provided with a return pipe near the outlet, and the lower ends of the water delivery pipe and the return pipe both penetrate and extend into the interior of the cold water pool.

[0009] Preferably, a feed inlet is provided at the left end of the distillation tower body at the upper side of the reaction barrel.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. By starting the hydraulic cylinder to lower its telescopic end, the reaction barrel can be driven down. When most of the hydrogen peroxide in the reaction barrel is immersed in the cold water of the cold water pool, the purpose of cooling can be achieved. This fast water cooling method can ideally prevent the hydrogen peroxide from continuing to decompose or explode under the action of residual heat.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-Figure 4 As shown, a purification distillation tower with a water cooling function comprises a distillation tower body 1 and a cold water pool 3, a reaction barrel 2 is arranged at the inner bottom of the distillation tower body 1, the outer wall of the reaction barrel 2 is fitted with the inner wall of the distillation tower body 1, the distillation tower body 1 and the cold water pool 3 are fixedly connected, a hydraulic cylinder 4 is fixedly installed at the inner bottom of the cold water pool 3, an adapter 5 is fixedly connected to the upper end of the hydraulic cylinder 4, a connecting seat 6 is rotatably connected to the middle of the lower end of the reaction barrel 2, the hydraulic cylinder 4 is rotatably connected to the connecting seat 6 through the adapter 5, a slave gear 7 is fixedly sleeved on the outer side of the connecting seat 6, a main gear 8 is meshed and connected to the right end of the slave gear 7, the output end of the driving motor 9 is fixedly plugged at the axis of the main gear 8, a stirring blade 11 is rotatably installed at the inner middle of the reaction barrel 2, and the lower end of the stirring blade 11 passes through the reaction barrel 2 and is fixedly connected to the connecting seat 6;

[0021] When most of the hydrogen peroxide in the reaction barrel 2 is immersed in the cold water of the cold water pool 3, the purpose of cooling can be achieved, and it is safe and fast. This fast water cooling method can ideally prevent the hydrogen peroxide from continuing to decompose or explode under the action of residual heat. In addition, by turning on the drive motor 9, the output end of the drive motor 9 drives the main gear 8 to rotate, and the rotation of the main gear 8 drives the rotation of the slave gear 7. The rotation of the slave gear 7 can drive the connecting seat 6 to rotate. Through the setting of the adapter 5, when the connecting seat 6 rotates, it will not affect the hydraulic cylinder 4, ensuring the rationality of the structure. The rotation of the connecting seat 6 can drive the stirring blade 11 to rotate, and the rotation of the stirring blade 11 can achieve the purpose of stirring and mixing, accelerate the fusion of hydrogen peroxide and the catalyst or organic solvent, improve the purification efficiency and the safety of distillation, and this solution has a simple structure, a reasonable design, and a low cost.

[0022] The lower end of the driving motor 9 is fixedly connected to a fixing frame 10 , and the upper end of the fixing frame 10 is fixedly connected to the reaction barrel 2 , which provides a fixing and supporting function for the driving motor 9 and ensures the rationality of the structural design.

[0023] Six groups of bonding plates 12 arranged in a circular array are fixedly connected to the inner bottom of the cold water pool 3. The inner wall of the bonding plate 12 is in contact with the reaction barrel 2. By starting the hydraulic cylinder 4 to lower its telescopic end, the reaction barrel 2 can be driven down. In this process, the bonding plate 12 provides a certain limit and support for the reaction barrel 2 to avoid tipping.

[0024] An air outlet pipe 13 is fixedly connected to the middle of the upper end of the distillation tower body 1, and the right end of the air outlet pipe 13 is connected to and fixedly connected to a condenser 14. A water supply pipe 15 is provided near the inlet of the condenser 14, and a reflux pipe 16 is provided near the outlet of the condenser 14. The lower ends of the water supply pipe 15 and the reflux pipe 16 penetrate and extend to the interior of the cold water pool 3. In the process of distilling hydrogen peroxide through the distillation tower body 1, the rising steam will enter the interior of the condenser 14 through the air outlet pipe 13, and the steam in the condenser 14 can be condensed repeatedly through the water supply pipe 15 and the reflux pipe 16. At the same time, the cold water pool 3 can maintain a low temperature effect of the clean water in the cold water pool 3 by using an external refrigeration equipment such as a chiller, and there is no need to add an additional device to cool the condensed water, thereby reducing costs.

[0025] A feed inlet 17 is provided at the left end of the distillation tower body 1 on the upper side of the reaction barrel 2 , through which hydrogen peroxide with a low content can be poured into the reaction barrel 2 at the bottom of the distillation tower body 1 .

[0026] Working principle:

[0027] When in use, hydrogen peroxide with a low content can be poured into the reaction barrel 2 at the bottom of the distillation tower body 1 through the feed port 17. In the process of distilling hydrogen peroxide through the distillation tower body 1, the rising steam will enter the interior of the condenser 14 through the outlet pipe 13. The steam in the condenser 14 can be condensed repeatedly through the water pipe 15 and the reflux pipe 16. At the same time, the cold water pool 3 can maintain a low temperature effect by connecting an external refrigeration device such as a chiller. Further, when the temperature of the hydrogen peroxide in the reaction barrel 2 is too high, or after the distillation is completed, the residual heat is prevented from continuing to decompose the hydrogen peroxide, and the reaction barrel 2 can be driven to descend by starting the hydraulic cylinder 4 to lower its telescopic end. In this process, the bonding plate 12 provides a certain limit and support for the reaction barrel 2 to avoid tipping. When most of the hydrogen peroxide in the reaction barrel 2 is immersed in the cold water of the cold water pool 3, it can reach a low temperature. The purpose of cooling is achieved safely and quickly. This fast water cooling method can ideally prevent hydrogen peroxide from continuing to decompose or explode under the effect of residual heat. In addition, in order to make the heating of hydrogen peroxide more stable and to better separate impurities during distillation, some organic solvents or catalysts are often needed to be added. By turning on the drive motor 9, the output end of the drive motor 9 drives the main gear 8 to rotate, and the rotation of the main gear 8 drives the rotation of the slave gear 7. The rotation of the slave gear 7 can drive the connecting seat 6 to rotate. Through the setting of the adapter 5, when the connecting seat 6 rotates, it will not affect the hydraulic cylinder 4, ensuring the rationality of the structure. The rotation of the connecting seat 6 can drive the stirring blade 11 to rotate. The purpose of stirring and mixing can be achieved by rotating the stirring blade 11, which accelerates the fusion of hydrogen peroxide and the catalyst or organic solvent, improves the purification efficiency and the safety of distillation, and the scheme has a simple structure, a reasonable design, and a low cost.
