Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment equipment, in particular to an electroplating wastewater spray evaporation separation device driven by industrial steam. Background Art

[0002] Currently, electroplating wastewater treatment primarily utilizes physical, chemical, and biological methods. Among these, spray evaporation technology, a physical method, is widely used due to its high efficiency and ease of operation. A typical electroplating wastewater spray evaporation separation system typically consists of a wastewater storage tank, a pump, an atomizing nozzle, and an evaporation chamber. The system operates by pumping wastewater from the storage tank to the atomizing nozzle, where it forms a fine mist within the evaporation chamber. The temperature of the evaporation chamber is then controlled to evaporate the water, thereby concentrating and separating pollutants from the wastewater.

[0003] In traditional technology, the pump is usually placed directly in the electroplating wastewater to extract the wastewater and use the atomizing nozzle to form water mist in the evaporation chamber. This design has some significant problems in practical application:

[0004] First, since electroplating wastewater contains a large amount of flocculants and impurities, these substances are easily sucked into the system during the pumping process and eventually accumulate at the atomizing nozzle, causing nozzle blockage. The blockage of the nozzle not only interrupts the treatment process, but also causes unstable operation of the device.

[0005] Second, in order to prevent the nozzle from being clogged, it needs to be cleaned and replaced regularly, which not only increases the maintenance cost of the equipment, but also reduces the overall production efficiency.

[0006] Therefore, we propose an industrial steam-driven electroplating wastewater spray evaporation separation device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0028] The present application provides an industrial steam driven electroplating wastewater spray evaporation separation device, which is mainly used to solve the problem in the prior art that electroplating wastewater contains a large amount of flocculants and impurities, which are easily sucked into the system during the pumping process and eventually accumulate at the atomizing nozzle, causing nozzle blockage. The nozzle blockage not only interrupts the treatment process, but also causes unstable operation of the device. The following technical solutions are provided. Figures 1-4 Give detailed instructions:

[0029] An industrial steam-driven electroplating wastewater spray evaporation separation device, comprising:

[0030] The water storage tank 1 has a water inlet pipe 101 in the middle of one side of the water storage tank 1, and a drain pipe 102 is connected to the bottom of the water storage tank 1;

[0031] The deflector 2 is connected to the top of the water storage tank 1. The deflector 2 is conical and has a connecting pipe 3 connected to the top. The connecting pipe 3 is externally connected to the condensing equipment.

[0032] The water storage tank 4 is fixed on the side wall of the water storage tank 1 and is used to store the filtered electroplating wastewater;

[0033] The sand filter mechanism 5 is used for preliminary filtration of the electroplating wastewater. The sand filter mechanism 5 includes a mounting cylinder 501 connected to the bottom of one side of the water storage tank 1. A filter cylinder 502 is connected to the upper side of the mounting cylinder 501 away from the water storage tank 1. A guide pipe 503 is connected between the upper side of the filter cylinder 502 and the water storage tank 4. A mesh cylinder 504 is provided inside the filter cylinder 502. The interior of the mesh cylinder 504 is filled with quartz sand 505. A hydraulic cylinder 506 is installed on the side wall of the water storage tank 1. The piston end of the hydraulic cylinder 506 penetrates the bulkhead of the water storage tank 1 and is connected to a plunger 507. The plunger 507 slides and is inserted into the interior of the mounting cylinder 501.

[0034] The spray evaporation component 6 is arranged inside the water storage tank 1 and is used for spray evaporating the electroplating wastewater in the water storage tank 4 .

[0035] Workflow Description:

[0036] In the first step, the electroplating wastewater to be treated is injected into the water storage tank 1 through the water inlet pipe 101, and the equipment is checked to ensure that all the connecting pipes 3 are leak-free and the water pump 601, electric heating rod 604 and other equipment are working properly;

[0037] In the second step, the hydraulic cylinder 506 is activated to push the plunger 507 to slide inside the installation cylinder 501. The electroplating wastewater flows from the water storage tank 1 into the installation cylinder 501. It is initially filtered by the mesh cylinder 504 filled with quartz sand 505. The filtered wastewater flows into the water storage tank 4 through the diversion pipe 503 and waits for further treatment.

[0038] In the third step, the water pump 601 is turned on to transport the filtered wastewater in the water storage tank 4 to the atomizing nozzle 603 through the drainage pipe 602. The wastewater is transformed into a fine mist under the action of the atomizing nozzle 603 and evenly distributed inside the water storage tank 1.

[0039] The fourth step is to turn on the electric heating rod 604 to heat the water mist in the water storage tank 1 to promote water evaporation;

[0040] In the fifth step, as the water evaporates, the generated water vapor flows upward, passes through the guide cover 2 and enters the connecting pipe 3. The water vapor is cooled in the condensation equipment and converted into liquid water, completing the condensation process;

[0041] Step 6: Open the drain pipe 102 to discharge the concentrated wastewater for further treatment and recycling.

[0042] The industrial steam-driven electroplating wastewater spray evaporation separation device performs preliminary filtration on the electroplating wastewater by setting up a sand filter mechanism 5, effectively removing flocculants and impurities in the wastewater, preventing these substances from being sucked into the system during the pumping process and eventually accumulating at the atomizing nozzle 603, thereby preventing the nozzle from clogging. Since the occurrence of nozzle clogging is effectively reduced, the maintenance frequency and cleaning cost of the equipment are reduced, and the overall production efficiency is improved.

[0043] like Figure 4 As shown, in some embodiments, the spray evaporation component 6 includes a water pump 601 installed in the water tank 4, and the water outlet end of the water pump 601 is connected to the drainage pipe 602. The other end of the drainage pipe 602 extends to the interior of the water storage tank 1, and an atomizing nozzle 603 is installed at its end. Electric heating rods 604 are installed at equal intervals above the atomizing nozzle 603 inside the water storage tank 1. More specifically, when the system starts working, the water pump 601 is first started to extract the filtered wastewater in the water storage tank 4 and transport it to the drainage pipe 602. The wastewater flows to the atomizing nozzle 603 under the guidance of the drainage pipe 602, and forms tiny water mist under the action of the nozzle. These water mists are evenly distributed in the water storage tank 1, increasing the contact area between water and air. At the same time, the electric heating rod 604 is energized for heating, and the generated heat is transferred to the water mist through convection and radiation. As the temperature rises, the water begins to evaporate and transform into water vapor. The generated water vapor flows upward, enters the connecting pipe 3 through the guide cover 2, and is finally cooled into liquid water by the condensing equipment.

[0044] like Figure 4 As shown, in some embodiments, the specifications of the heating rod 604 gradually increase from bottom to top, and its shape is annular. More specifically, the annular heating rod 604 has a larger heating area than the linear or point-shaped heating rod 604, which means that under the same power, the annular heating rod 604 can more effectively transfer heat to the water mist. When multiple annular heating rods 604 are arranged according to a certain pattern, a mesh-like structure will be formed between them. This structure not only increases the heating area, but also promotes the uniform distribution of heat in space.

[0045] like Figure 4 As shown, in some embodiments, the top of the filter cartridge 502 is an open structure, and is threadedly connected to a cartridge cover 5021, and the mesh cartridge 504 is slidably inserted into the interior of the filter cartridge 502. More specifically, the threaded connection method can ensure a tight fit between the cartridge cover 5021 and the filter cartridge 502, preventing wastewater leakage and entry of external impurities. The mesh cartridge 504 is installed inside the filter cartridge 502 in a sliding and interlaced manner without the use of additional tools or fasteners. This design makes the installation and disassembly of the mesh cartridge 504 very simple and quick, greatly saving time and effort.

[0046] like Figure 4 As shown, in some embodiments, a limiting plate 508 is fixedly provided at the connection between the filter cylinder 502 and the mounting cylinder 501, and a lifting plate 5041 is fixedly provided at the upper end of the mesh cylinder 504. More specifically, the main function of the limiting plate 508 is to support the mesh cylinder 504, and the lifting plate 5041 enables the operator to easily lift or move the mesh cylinder 504.

[0047] like Figure 4 As shown, in some embodiments, a triangular notch 5071 is constructed at the bottom of one end of the plunger 507 located inside the mounting cylinder 501. More specifically, the design of the triangular notch 5071 can significantly reduce the flow resistance of wastewater when entering the mounting cylinder 501, and the wastewater can smoothly enter the interior of the mounting cylinder 501 through the notch. In addition, the design of the triangular notch 5071 makes it easier for the plunger 507 to enter and exit the mounting cylinder 501.

[0048] like Figure 2 As shown, in some embodiments, a transparent observation window 103 is provided on the front of the water storage tank 1. More specifically, the transparent observation window 103 can intuitively display the water level and wastewater treatment status in the water storage tank 1, so that the operator can understand the current water level without opening the tank cover or performing other complicated operations. This helps to promptly discover and deal with abnormal water level problems and prevent equipment failures caused by excessively high or low water levels.

[0049] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
