Description
Technical Field
[0001] The utility model relates to the technical field of etching solution circulation and regeneration, in particular to an etching solution reuse medicine preparation heat exchange energy-saving structure and device. Background Technique
[0002] During the etching solution circulation and regeneration process, it is necessary to pass cooling water through the reuse system to cool down the reuse system to ensure the normal operation of the reuse system; generally, a chiller is used to cool the reuse system. The chiller generates cooling water, and the cooling water flows through the reuse system through pipelines to take away the heat generated by the reuse system. The cooling water passing through the reuse system returns to the chiller to continue refrigeration, so that the reuse system can be continuously cooled during the working process. During the working process of the reuse system, it is necessary to keep the chiller working continuously. The continuous operation of the chiller will increase the energy consumption output and increase the production cost.
[0003] During the acid etching solution circulation and regeneration process, it is necessary to prepare the regenerated solution so that the acidity or chloride ion concentration or ammonium value of the regenerated solution meets the requirements. Generally, ammonium chloride is used as the medicine for preparation. In the acid reuse system, generally 2 to 4 tanks of regenerated solution can be prepared in a day, and about 25 - 37.5 kg of ammonium chloride is required for each tank; heat is absorbed during the dissolution process of ammonium chloride, and the heat of fusion is 14.8 kj / mol. The decrease in temperature will cause the solubility of ammonium chloride to decrease, resulting in the phenomenon that ammonium chloride is difficult to dissolve in a short time; in autumn and winter, when the ambient temperature is lower than 20°C, the solubility of ammonium chloride decreases significantly, prolonging the preparation time of the regenerated solution. Therefore, when the ambient temperature is lower than 20°C, it is necessary to heat the medicine preparation tank to shorten the dissolution time of ammonium chloride and improve the medicine preparation efficiency.
[0004] In the reuse system, the refrigeration processes of the electrolytic cell, rectifier, etc. in the reuse system and the heating process of the medicine preparation tank are independent of each other. The electrolytic cell, rectifier, etc. need to be refrigerated by a separate chiller, and the medicine preparation tank needs to be heated by a separate heating device. The refrigeration machine and the heating device have high operating power and high energy consumption, which will increase the production cost and do not conform to the concept of green production; moreover, there are certain safety hazards in heating the medicine preparation tank with a heating device; during the heating process of the medicine preparation tank, generally heating wires are arranged at the bottom of the medicine preparation tank to heat the bottom of the medicine preparation tank. The temperature at the bottom of the medicine preparation tank is high, while the temperature of the other parts is low, and there will also be problems of uneven heating.

[0030] Hot water enters the heat exchange tube 1 from the water inlet 2 and circulates in the spiral coil-structured heat exchange tube 1, uniformly transferring heat to the liquid to be heated, and can uniformly heat the liquid.
[0031] Two openings are arranged on the heat exchange tube 1, and the two openings are respectively located at the head end and the tail end of the heat exchange tube 1. Figure 1Among them, the two openings are respectively located at the top (tail end) and the bottom (head end) of the heat exchange tube 1. The bottom opening is the water inlet 2, and the top opening is the water outlet 3 (the bottom opening can also be the water outlet, and the top opening can also be the water inlet, and their positions can be interchanged).
[0032] Three openings can also be provided on the heat exchange tube 1. Among them, two openings are respectively located at the head end and the tail end of the heat exchange tube 1, and the third opening is located in the middle of the heat exchange tube 1. Refer to Figure 2 , both the top opening and the bottom opening of the heat exchange tube 1 are the water inlet 2, and the middle opening is the water outlet 3; adopting this structure can further increase the uniformity of liquid heating.

[0033] During the application process, a double-layer heat exchange tube 1 can also be adopted. Refer to Figure 3 , in the radial direction of the installation of the heat exchange tube 1, the spiral radius of the second-layer heat exchange tube 1 is not greater than that of the first-layer heat exchange tube 1 ( Figure 3 In, the spiral radii of the first-layer heat exchange tube and the second-layer heat exchange tube are equal, and they are staggered in the height direction), the first-layer heat exchange tube 1 and the second-layer heat exchange tube 1 are coaxial, and the first-layer heat exchange tube 1 and the second-layer heat exchange tube 1 are connected by a connecting rod 5 to improve the structural stability of the first layer and the second layer of heat exchange tubes. For the second-layer heat exchange tube 1, its top opening and bottom opening are the water inlet 2, and the water outlet 3 is arranged in the middle of the second-layer heat exchange tube 1. For the first-layer heat exchange tube 1, its top opening and bottom opening are the water outlets 3, and the water inlet 2 is arranged in the middle of the first-layer heat exchange tube 1 (the water inlet positions and water outlet positions of the first-layer heat exchange tube and the second-layer heat exchange tube can be swapped; the water inlet arrangement positions of the first layer and the second layer of heat exchange tubes can also be the same, and the water outlet arrangement positions can also be the same).

[0036] The present utility model also provides an etching solution recycling, medicine preparation, heat exchange and energy saving device. Referring to Figure 4 、 Figure 5 , this energy saving device includes the heat exchange tube 1 in Embodiment 1, and also includes a medicine preparation cylinder 6. The medicine preparation cylinder 6 is cylindrical. The heat exchange tube 1 is coaxially arranged inside the medicine preparation cylinder 6. The heat exchange tube 1 is fixedly connected to the inner wall of the medicine preparation cylinder 6 through a connecting rod (not shown) to ensure the stability of the connection between the heat exchange tube 1 and the medicine preparation cylinder 6.
[0037] Referring to Figure 4 , the heat exchange tube 1 extends from the bottom to the top of the medicine preparation cylinder 6. The heat exchange tube 1 can evenly transfer heat into the medicine preparation cylinder 6. Compared with the method of setting a resistance wire for heating inside the medicine preparation cylinder 6, the heat exchange tube 1 can make the solution inside the medicine preparation cylinder 6 receive heat evenly, and can also avoid potential safety hazards during the heating process of the medicine preparation cylinder 6. The water inlet of the heat exchange tube 1 is connected to the water inlet of the medicine preparation cylinder, and the water outlet of the heat exchange tube 1 is connected to the water outlet of the medicine preparation cylinder.
[0038] A cylinder cover 8 is arranged on the top of the medicine preparation cylinder 6. A stirring column 9 is also arranged inside the medicine preparation cylinder 6. A motor 10 (which can be a servo motor or a stepper motor) is installed on the cylinder cover 8. The motor 10 is connected to the stirring column 9 to stir the solution inside the medicine preparation cylinder 6, accelerate the dissolution rate of the medicine, thereby improving the medicine preparation efficiency and production efficiency; during the stirring process, the solution can also be dispersed to various parts of the medicine preparation cylinder 6, improving the heat exchange efficiency between the heat exchange tube 1 and the solution.
[0039] Stirring blades 11 are also arranged on the outer surface of the stirring column 9. Multiple groups of stirring blades are arranged along the height direction of the stirring column 9. The stirring blades 11 can increase the contact area between the medicine and the solution, and make the medicine and the solution mix evenly.
[0040] The stirring column 9 is of a cylindrical structure, with an opening coaxially provided at its bottom. The opening extends from the bottom to the top of the stirring column 9 to form a medicine discharge channel 12. A second feed port 13 is provided at the top of the stirring column 9; a connecting column 16 is coaxially provided at the bottom of the cylinder head 8. An installation channel is provided in the middle of the connecting column 16. The top of the stirring column 9 passes through the installation channel and is connected to the motor 10; a feed channel is provided between the installation channel of the connecting column 16 and the outer wall of the connecting column 16. The bottom of the feed channel is open. A third feed port is also provided on the outer wall of the connecting column 16. A first feed port 14 is provided on the cylinder head 8. The first feed port 14 and the third feed port are connected by a feed pipe 15; without opening the cylinder head 8, medicines can be added to the medicine preparation cylinder 6 (medicines can also be added by opening the cylinder head 8). The medicines enter the feed channel of the connecting column 16 through the feed pipe 15, pass through the opening at the bottom of the feed channel and the second feed port 13 at the top of the stirring column 9, enter the interior of the stirring column 9, and enter the solution from the opening at the bottom of the stirring column 9. Further, one or more discharge ports 17 are provided in the height direction of the stirring column 9 (refer to Figure 4 , Figure 6 ). The discharge ports 17 communicate with the discharge channel 12. During the rotation of the stirring column 9, the medicines can enter the solution from the discharge ports 17 on the stirring column 9, improving the uniformity of medicine addition; when the discharge ports 17 are provided on the stirring column 9, the bottom of the stirring column 9 can also be closed with a bottom cover.
[0041] Baffles 7 are also provided on the inner wall of the medicine preparation cylinder 6 (refer to Figure 4 , Figure 5 ). During the stirring process of the stirring column 9, the baffles 7 can increase the turbulence degree of the solution, change the fluid motion into axial and radial flows, reduce the generation of vortex phenomena, so that the medicines are fully contacted with the solution, the medicines are evenly mixed in the solution, and the solubility and dissolution rate of the medicines are improved. A plurality of baffles 7 are circumferentially provided on the inner wall of the medicine preparation cylinder 6.
[0042] The energy-saving device further includes a dilution cylinder, which is connected to the medicine preparation cylinder 6 (not shown). In the medicine preparation cylinder 6, the concentration of medicine preparation can be increased, and the prepared medicines can be used as a standby. When medicines with the required concentration are to be obtained, the medicines in the medicine preparation cylinder 6 can be introduced into the dilution cylinder and diluted with water to obtain the required medicine concentration; compared with single-time medicine preparation, the method of dilution with water improves the medicine preparation efficiency and speeds up the production efficiency.
[0043] The etching solution recycling, chemical preparation, heat exchange and energy saving device of the utility model can be used in combination with a recycling system (which can be an acidic recycling system or an alkaline recycling system) to reduce energy consumption. The recycling system includes a chiller 20, an electrolytic cell 18 and a rectifier 19; the outlet of the cooling pipe of the electrolytic cell 18 is connected to the inlet of the chemical preparation tank 6, the outlet of the cooling pipe of the rectifier 19 is connected to the inlet of the chemical preparation tank 6, and the outlet of the chemical preparation tank 6 is connected to the chiller 20.
[0044] During the operation of the electrolytic cell 18 and the rectifier 19, heat will be generated. During the cooling process of the electrolytic cell 18 and the rectifier 19 by the cooling water, the cooling water will be heated into hot water. The hot water enters the chemical preparation tank 6. Under the action of the heat exchange pipe, the hot water spirally moves along the chemical preparation tank 6 in the chemical preparation tank 6 to heat the chemical preparation tank 6 (the heating temperature is not less than 20 °C), which speeds up the dissolution rate of the medicine in the chemical preparation tank 6. The medicine in the chemical preparation tank 6 is ammonium chloride. Ammonium chloride absorbs heat during dissolution. During the heating process of the hot water on the chemical preparation tank 6, ammonium chloride cools down the hot water. Thus, the water flowing into the chemical preparation tank 6 is hot water, and the water flowing out of the chemical preparation tank 6 is cold water, realizing the heat exchange of the energy saving device. Under the action of the chemical preparation, heat exchange and energy saving system, not only the dissolution rate of ammonium chloride is accelerated, but also the chemical preparation efficiency is accelerated; moreover, the cold water can be generated not only by the chiller 20, but also by the energy saving device. Under the action of the energy saving device, the refrigeration output of the chiller is reduced, and the working energy consumption of the chiller is reduced.

Various substitutions, modifications and improvements made by those skilled in the relevant technical fields without departing from the principle and scope of the utility model shall be included within the protection scope of the utility model.
