[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0020] Combine Figure 1-Figure 3 The utility model provides a 4-CN crystallization kettle device, comprising a crystallization kettle body 1 and a condensed water storage device 2. The output end of the condensed water storage device 2 is connected to the crystallization kettle body 1 through a delivery pipe 21. The condensed water storage device 2 collects the condensed water of the high-pressure steam in the workshop and adds it to the crystallization kettle body 1. This can solve the water required for the crystallization process and the large amount of heat energy required for the dissolution process, while also avoiding the problem of waste of resources.

[0021] The upper end of the condensed water storage device 2 is provided with a condensed water inlet 22. Although the condensed water is pure distilled water, it may be contaminated during the transmission process. Therefore, a filter component 23 is provided in the condensed water storage device 2. The filter component 23 performs multiple filtrations on the condensed water to remove particles and bacteria so that the condensed water can meet the needs of use. Specifically, the filter component 23 includes a metal mesh filter layer 231, a quartz sand filter layer 232, an activated carbon filter layer 233 and a ceramic filter layer 234. The condensed water passes through the metal mesh filter layer 231, the quartz sand filter layer 232, the activated carbon filter layer 233 and the ceramic filter layer 234 in sequence. 232, activated carbon filter layer 233 and ceramic filter layer 234 filter, the metal mesh filter layer 231 removes large particles of impurities with a diameter greater than 100 microns, the quartz sand filter layer 232 serves as the second layer of filter medium to remove particles with a diameter between 50-100 microns, the activated carbon filter layer 233 is used to adsorb organic matter and some chemical substances in the water to improve water quality, and the ceramic filter layer 234 further removes particles smaller than 50 microns. A backwash pipe 24 is provided below the ceramic filter layer 234 and is connected to a backwash pump to regularly remove accumulated impurities.

[0022] The condensed water storage device 2 below the filter assembly 23 has a storage space, and the filtered condensed water is collected here. A water delivery pump 25 is provided on the outer wall of the lower end of the condensed water storage device 2. The water delivery pump 25 outputs the condensed water through the insulation pipe 251 connected to the output end. At the same time, one end of the insulation pipe 251 is connected to a continuous U-shaped pipe 26. Both ends of the continuous U-shaped pipe 26 pass through the side wall of the condensed water storage device 2, and one end of the continuous U-shaped pipe 26 is fixedly connected to the delivery pipe 21. The continuous U-shaped pipe 26 is located in the filter assembly 2 inside the condensed water storage device 2. The condensed water entering the condensed water storage device 2 above the component 23 is first stored in the space above the filter component 23, and gradually passes through the filter component 23 and enters the bottom of the condensed water storage device 2. The temperature of the condensed water just entering the condensed water storage device 2 is high, and part of the condensed water will vaporize and rise again, contacting the continuous U-shaped tube 26, heating the condensed water in the continuous U-shaped tube 26, and increasing the temperature of the condensed water entering the crystallization kettle body 1. At the same time, the vaporized water vapor contacts the continuous U-shaped tube 26 with a lower temperature and can condense when it is cold.

[0023] A flow meter 211 for controlling the flow of condensed water is provided on the delivery pipeline 21 , and a water inlet valve 212 is provided at the connection between the delivery pipeline 21 and the crystallization kettle body 1 , through which the inlet of condensed water is controlled.

[0024] The crystallization kettle body 1 is a conical kettle body with an interlayer. A motor 11 is installed at the upper end of the crystallization kettle body 1. The output end of the motor 11 passes through the top of the crystallization kettle body 1 and is connected to a stirring paddle 12. A thermometer 13 and a feed port 14 are provided on the crystallization kettle body 1 on both sides of the motor 11. A discharge port 15 is provided at the lower end of the crystallization kettle body 1, and lifting ears 16 are also provided on both sides of the crystallization kettle body 1.

[0025] Working process: The condensed water is loaded into the condensed water storage device 2, filtered in sequence through the metal mesh filter layer 231, the quartz sand filter layer 232, the activated carbon filter layer 233 and the ceramic filter layer 234 to remove solid particles and pollutants in the condensed water, and stored at the bottom of the condensed water storage device 2. When the new 4-CN crystallization reactor device is needed, the water inlet valve 212 is opened first, and the water pump 25 adds a certain amount of condensed water into the crystallization reactor body 1. During the process, the condensed water is heated through the continuous U-shaped tube 26 to maintain a high temperature, and then the feed port 14 is opened to add a certain amount of mixed cyanopyridine. The motor 11 is driven to drive the stirring paddle 12 to stir, cool down and crystallize, and the thermometer 13 monitors the temperature inside the crystallization reactor body 1. The discharge port 15 is opened and the material is centrifuged.
