Description

Technical Field

[0001] This invention relates to the field of waste liquid treatment, and more specifically, to a chemical waste liquid recycling and treatment device. Background Technology

[0002] In the process of chemical production, a large amount of high-temperature waste liquid is generated. This waste liquid usually contains corrosive, toxic or high-concentration organic components. If it is discharged directly without effective treatment, it will cause serious harm to the environment and human health. Therefore, the recycling and cooling treatment of waste liquid is one of the key links in industrial wastewater management. Among them, cooling, as an important pretreatment step, not only affects the efficiency of subsequent treatment processes, but also directly relates to the safe operation of equipment and energy consumption control.

[0003] Traditional waste liquid cooling methods often employ simple natural cooling or single water-cooled piping systems. These methods generally suffer from low heat exchange efficiency, slow cooling speed, and uneven temperature distribution. Especially when treating waste liquids with high heat loads, traditional devices struggle to achieve rapid and uniform heat exchange, resulting in long processing cycles, high energy consumption, and even potential safety hazards due to localized overheating. Furthermore, in actual operation, the poor fluidity of the waste liquid also affects heat transfer, further reducing overall cooling efficiency. Simultaneously, most existing equipment lacks effective gas-liquid interaction design, failing to fully utilize the auxiliary cooling effect of air convection, thus limiting the improvement of the system's overall performance. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention aims to provide a chemical waste liquid recycling and treatment device. This device uses spray holes to evenly disperse circulating cooling water into the main body, significantly increasing the contact area between the water and the waste liquid and improving heat exchange efficiency.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 7 A chemical waste liquid recycling and treatment device includes a main body 1. A water outlet pipe 11 is provided on one side of the bottom of the main body 1, and a water inlet pipe 12 is provided on the top of the main body 1. A cooling mechanism 2 is provided inside the main body 1 for cooling the circulating waste liquid. The cooling mechanism 2 includes a sealing cover 21 that rotates on the top of the main body 1. An installation plate 22 is fixed on the surface of the sealing cover 21 near the main body 1. A connecting groove 23 is opened inside the installation plate 22, and a spray hole 24 communicating with the connecting groove 23 is opened on the outer circular surface of the installation plate 22. A rotating motor 25 is fixedly installed on the surface of the sealing cover 21 away from the main body 1, and an electric telescopic rod 26 is fixedly installed at the output end of the rotating motor 25.

[0020] like Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the cooling mechanism 2 also includes a synchronization block 27 fixed to the output end of the electric telescopic rod 26. A rotating rod 28 is rotatably connected inside the main body 1. Multiple cleaning blocks 210 are fixedly installed at equal intervals on the surface of the rotating rod 28. A synchronization groove 211 is opened on the surface of the rotating rod 28 near the sealing cover 21. An air blower 212 is fixedly installed at the bottom inside the main body 1. Air blowing holes 213 are evenly opened on the surface of the air blower 212 near the sealing cover 21. An air supply component 214 is fixedly installed at the bottom of the main body 1. A cooling mechanism 29 is provided on the surface of the main body 1.

[0021] It should be noted that one-way valves are installed in multiple air holes 213. The one-way valves can block water in the main body 1 so that water will not enter the air holes 213 and thus will not affect the operation of the air holes 213.

[0022] like Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the plurality of cleaning blocks 210 are preferably four, and the bottom of the four cleaning blocks 210 and the opposite side connected to the rotating rod 28 are respectively slidably connected to the upper surface of the air blower 212 and the inner circular surface of the main body 1.

[0023] like Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the synchronization block 27 and the synchronization groove 211 are equilateral polygons, and the synchronization block 27 and the synchronization groove 211 are adapted to each other. The synchronization groove 211 is located below the synchronization block 27. One end of the water inlet pipe 12 is fixedly connected to the upper surface of the mounting plate 22. The middle part of the mounting plate 22 is hollow.

[0024] like Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the air supply component 214 includes an air supply pipe that is fixedly connected to and communicates with the air blower 212. A first air blower is fixedly installed at one end of the air supply pipe, and a filter screen is fixedly installed on the suction pipe of the first air blower.

[0025] In actual use, the cooling effect on the waste liquid is not good, which in turn affects the cooling effect of the waste liquid on the coolant. Based on this, a cooling mechanism 2 is set up. When it is necessary to cool the waste liquid, the used waste liquid is first transported to the connecting groove 23 inside the mounting plate 22 through the water inlet pipe 12, and then sprayed out in all directions from the inside of the spray hole 24. Part of the sprayed waste liquid will contact the inner wall of the main body 1 to achieve initial cooling of the waste liquid. After the waste liquid falls into the interior of the main body 1, the output end of the rotating motor 25 is controlled to rotate by the control switch. The rotation of the output end of the rotating motor 25 will drive the electric telescopic rod 26 to rotate, and the rotation of the electric telescopic rod 26 will drive the synchronous block 27 to rotate, thereby... Under the action of the synchronization block 27 and the synchronization groove 211, the rotating rod 28 and the cleaning block 210 are driven to rotate. The rotation of the cleaning block 210 increases the fluidity of the water and allows the cleaning block 210 to fully contact the waste liquid, thereby improving the removal effect of impurities in the water. At the same time, the air supply component 214 blows air into the air blower 212, allowing the air to enter the interior of the main body 1 through the air blowing hole 213. This increases the fluidity of the water inside the main body 1. When the air flows in the waste liquid, it can also cool the waste liquid to a certain extent. Furthermore, when the air flows upward, it comes into contact with the waste liquid dispersed in all directions by the spray hole 24, which can further cool the waste liquid and optimize the cooling rate of the waste liquid.

[0026] In the above process, in order to ensure that the waste liquid sprayed from the spray hole 24 is not affected when it spreads in all directions, the highest water level inside the main body 1 cannot exceed the spray hole 24. The cleaning block 210 is made of activated carbon, and filter holes that penetrate both sides are opened inside the cleaning block 210. When the cleaning block 210 rotates, it can push the waste liquid while ensuring the normal flow of the waste liquid. When the cleaning block 210 needs to be replaced or cleaned, first control the output end of the electric telescopic rod 26 to retract. The retraction of the output end of the electric telescopic rod 26 will cause the synchronization block 27 to no longer be located inside the synchronization groove 211. Then, by releasing the limit on the sealing cover 21, the sealing cover 21 is rotated so that the sealing cover 21 no longer seals the top of the main body 1. Then the cleaning block 210 can be taken out for replacement or cleaning. The sealing cover 21 is provided with an exhaust hole to discharge the air inside the main body 1.

[0027] like Figures 2-4As shown, the cooling mechanism 29 includes a water storage tank 291 fixed to the bottom of the main body 1. A partition plate 292 is fixed to the inner surface of the water storage tank 291. A diversion tube 293 is fixedly installed on the outer circular surface of the main body 1 above the partition plate 292. A water outlet 294 is opened on one side of the surface of the diversion tube 293. An installation tube 295 is fixedly installed on the outer circular surface of the main body 1 at the top of the main body 1. Flow ports 296 are evenly opened on the lower surface of the installation tube 295 near the main body 1. A water pipe 297 is fixedly installed on the lower surface of the installation tube 295. A water pump 298 is fixedly installed at the bottom end of the water pipe 297. A cooling pipe 299 is fixedly installed in the middle of the water storage tank 291. Cooling holes 2910 are opened on both sides and the top surface of the cooling pipe 299. A second blower 2911 is fixedly connected to the bottom of the cooling pipe 299 through the installation tube. A protective plate 2912 is provided on one side of the water outlet 294.

[0028] Water is guided to one side of the partition plate 292 through the diversion tube 293 and the outlet 294, while the water pump 298 is on the other side of the partition plate 292. The purpose is to maximize the water flow path and thus improve the cooling effect of the water. The protective plate 2912 installed at the outlet 294 blocks the water discharged from the inside of the outlet 294 to prevent the water flow from being too large and thus preventing the water from entering the inside of the water storage tank 291.

[0029] like Figures 2-4 As shown, the pumping end of the water pump 298 is located inside the water storage tank 291, and the water pump 298 and the outlet 294 are located on both sides of the partition plate 292, respectively. The radius of the diversion tube 293 is smaller than the radius of the water storage tank 291.

[0030] like Figures 2-4 As shown, the flow port 296 is in contact with the main body 1, the water pipe 297 and the mounting cylinder 295 are interconnected, the protective plate 2912 is fixedly connected to the diversion cylinder 295, and one end of the protective plate 2912 is located below the water outlet 294.

[0031] In actual use, cooling the main body 1 using only one method is not very effective. Therefore, a cooling mechanism 29 is set up. When it is necessary to cool the surface of the main body 1, the water pump 298 is first controlled by the control switch to run, so that the water pump 298 draws water from the water storage tank 291. Then, the water enters the installation cylinder 295 through the water pipe 297, and then flows out from the flow port 296 at the bottom of the installation cylinder 295. The water flowing out of the flow port 296 flows down along the surface of the main body 1, cooling the surface of the main body 1 as it flows. Then, the water flows into the water storage tank 291. After the water enters the water storage tank 291, the second blower 2911 blows air into the cooling pipe 299. The air entering the cooling pipe 299 flows through the cooling hole 2910. Part of the exhaust air enters the water, increasing the water flow and improving the cooling speed of the water. The other part blows onto the surface of the main body 1. The cooling speed of the surface of the main body 1 is optimized by the cooperation of water flow and air.

[0032] It should be noted that a one-way valve is installed on the cooling hole 2910 to block water from entering the cooling hole 2910 and affecting its operation.

[0033] The cooling pipe 299 is installed inside the water storage tank 291. The downward flowing water first contacts the cooling pipe 299, which raises the surface and inner surface temperature of the cooling pipe 299. The continuous blowing of the second blower 2911 allows some air to enter the water, increasing the water's fluidity. It also increases the airflow inside the cooling pipe 299 as it flows, thereby reducing the instability of the inner surface of the cooling pipe 299 and further improving the cooling effect on the circulating water.

[0034] Instructions for use: When in use, firstly, the waste liquid after use is transported to the connecting groove 23 inside the mounting plate 22 through the water inlet pipe 12, and then sprayed out in all directions from the inside of the spray hole 24. Some of the sprayed waste liquid will contact the inner wall of the main body 1 and fall into the interior of the main body 1. After that, the output end of the rotating motor 25 is rotated by the control switch, which can drive the cleaning block 210 to rotate. The rotation of the cleaning block 210 increases the flow of water and makes the cleaning block 210 and the waste liquid fully contact each other. At the same time, the air supply component 214 blows air into the air blower 212, which increases the flow of water inside the main body 1. At the same time, the air flowing in the waste liquid can also cool the waste liquid to a certain extent. When it is necessary to cool the surface of the main body 1, the water pump 298 is first controlled to operate, so that the water pump 298 draws water from the water storage tank 291, and then flows out from the flow port 296 at the bottom of the mounting cylinder 295. The water flowing out of the flow port 296 flows down along the surface of the main body 1 to cool the surface of the main body 1. Finally, it flows into the water storage tank 291. Then, the second blower 2911 blows air into the cooling pipe 299, so that the air entering the cooling pipe 299 flows through the cooling hole 2910. Part of the exhaust air enters the water to increase the water flow and improve the cooling speed of the water, and the other part blows onto the surface of the main body 1. The cooling speed of the surface of the main body 1 is optimized by the cooperation of water flow and air.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
