Description

Technical Field

[0001] This invention relates to the field of industrial wastewater treatment technology, and more specifically, to a combined device and method for removing high concentrations of sulfate from industrial wastewater. Background Technology

[0002] Industrial wastewater includes production wastewater, industrial sewage, and cooling water. It refers to wastewater and waste liquid generated during industrial production processes, containing industrial raw materials, intermediate products, by-products, and pollutants lost with the water. Industrial wastewater is diverse and complex in composition. When treating industrial wastewater, the first step is to remove the high concentration of sulfate ions.

[0003] Currently, when removing high-concentration sulfate from industrial wastewater, quicklime needs to be added to the wastewater, either by equipment or manually. The high-concentration sulfate is removed through the reaction of quicklime with the sulfate. However, current sulfate removal equipment often results in excessive quicklime addition, leading to waste. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a combined device and method for removing high-concentration sulfate ions from industrial wastewater.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A combined device for removing high-concentration sulfate ions from industrial wastewater includes an upper combined chamber and a lower combined chamber. First fixing plates are fixedly installed on both outer walls of the upper combined chamber, and second fixing plates are fixedly installed on both outer walls of the lower combined chamber. The two first fixing plates and two second fixing plates correspond one-to-one. The first and second fixing plates are arranged vertically, and a central plate is provided between the first and second fixing plates. A guide rod is fixedly installed on the central plate, and both the first and second fixing plates are slidably mounted on the guide rod.

[0007] A ash storage box is fixedly installed on the top of the inner wall of the upper combination chamber, and an ash conveying pump is fixedly installed on the bottom of the outer wall of the ash storage box. The ash pump's ash suction port is connected to the bottom of the ash storage box, and the ash pump's ash discharge port is connected to the ash conveying pipe.

[0008] A lifting assembly is fixedly installed on the top of the upper combined chamber wall. The lifting assembly can be a cylinder or a hydraulic cylinder. A lifting plate is provided on one side of the lifting assembly. The lifting assembly is used to drive the lifting plate to rise and fall. A rotating tube is rotatably installed on the lifting plate. The top of the rotating tube is connected to the lower ash hopper. An ash outlet is opened on the rotating tube. Multiple stirring rods are fixedly installed on the rotating tube.

[0009] A sealing plate is fixedly installed in the lower assembly chamber, a drainage pipe is connected to the sealing plate, a filter screen is fixedly installed inside the drainage pipe, and a switch valve is fixedly installed on the drainage pipe.

[0010] A removal detection head is fixedly installed at the bottom of the lifting plate. The removal detection head includes a removal detection module, which is used to control the opening and closing of the ash conveying pump and the switching valve. Specifically, it continuously takes pictures of the industrial wastewater in the lower combination chamber at the same time interval, marks the pictures as removal pictures, uses the removal pictures as input data for the removal analysis model, obtains the image labels of the output data of the removal analysis model, and marks the image labels of the output data as removal values. It obtains n removal values ​​obtained before the current time, sorts the removal values ​​according to the shooting time of the corresponding removal pictures, marks the adjacent and earlier removal values ​​after sorting as the next-near removal value, marks the adjacent and later removal values ​​after sorting as the next-near removal value, calculates the difference between the next-near removal value and the next-near removal value to obtain the removal change value, and marks it as Tb. It sets the removal change value threshold as Ez. When the removal change value Tb ≥ the removal change value threshold Ez, no processing is performed. When the removal change value Tb < the removal change value threshold Ez, the removal detection module controls the ash conveying pump to close and controls the switching valve to open.

[0011] Furthermore, the upper and lower combination chambers are arranged vertically, and a support rod is fixedly installed on the central plate.

[0012] Furthermore, a mounting plate is fixedly installed on the top of the guide rod, and a combination assembly is fixedly installed on the mounting plate. A ball screw is provided on one side of the combination assembly. The combination assembly can be a motor or a rotary cylinder. The combination assembly is used to drive the ball screw to rotate. The threaded surfaces at both ends of the ball screw are symmetrically arranged along the middle. The two ends of the ball screw are respectively threaded to a first fixing plate and a second fixing plate.

[0013] Furthermore, a lime feed hopper is fixedly installed on the top of the outer wall of the upper assembly room, and the bottom of the lime feed hopper is connected to the top of the ash storage box.

[0014] Furthermore, a lifting rod is fixedly installed on the top of the upper combined interior wall, and the bottom of the lifting rod is fixedly connected to the top of the lifting plate.

[0015] Furthermore, a rotating assembly is fixedly installed on the lifting plate. The rotating assembly may be a motor or a rotary cylinder. A first gear is provided on one side of the rotating assembly, and the rotating assembly is used to drive the first gear to rotate. A second gear is fixedly installed on the rotating tube, and the first gear and the second gear mesh with each other.

[0016] Furthermore, a wastewater inlet pipe is connected to one side of the outer wall of the lower assembly chamber, and a wastewater outlet pipe is connected to the other side of the outer wall of the lower assembly chamber.

[0017] Furthermore, the removal analysis model is obtained through the following steps: obtaining multiple removal photos, labeling the removal photos as training images, assigning image labels to the training images, dividing the training images into training and validation sets according to a set ratio, constructing a neural network model, iteratively training the neural network model using the training and validation sets, determining that the neural network model has completed training when the number of iterations exceeds the iteration threshold, and labeling the trained neural network model as the removal analysis model. The larger the image label value, the more sediment is found in the removal photo.

[0018] Furthermore, a combined method for removing high-concentration sulfate ions from industrial wastewater includes the following steps:

[0019] Step 1: Add quicklime into the quicklime feed hopper. The quicklime enters the ash storage box through the quicklime feed hopper. Industrial wastewater enters the lower combined chamber above the sealing plate through the wastewater inlet pipe. Then, start the lifting assembly. The lifting assembly drives the lifting plate to descend. The lifting plate drives the lifting rod to extend, and then the lifting plate descends into the lower combined chamber. The industrial wastewater is placed between the lifting plate and the sealing plate.

[0020] Step Two: Turn on the ash pump. The ash pump draws quicklime from the ash storage box. The quicklime enters the lower ash hopper through the ash conveying pipe. The quicklime in the lower ash hopper enters the rotating tube. Start the rotating assembly. The rotating assembly drives the first gear to rotate. The first gear meshes and drives the second gear to rotate. The second gear drives the rotating tube to rotate. The rotating tube drives the stirring rod to rotate. The stirring rod stirs the industrial wastewater. During the rotation of the rotating tube, quicklime is thrown out from the ash outlet. The quicklime reacts with the high concentration of sulfate in the industrial wastewater, producing precipitate. After the high concentration of sulfate in the industrial wastewater is removed, the removal detection head controls the ash pump to shut off and controls the switch valve to open. The industrial wastewater after the high concentration of sulfate is removed flows into the bottom of the lower combined chamber through the diversion pipe. Then, the industrial wastewater flows out through the wastewater outlet pipe. Finally, start the combined assembly. The combined assembly drives the ball screw to rotate. The ball screw drives the first fixed plate and the second fixed plate to move in opposite directions. Then, the upper combined chamber and the lower combined chamber move in opposite directions. Finally, the precipitate can be removed from the sealing plate.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The upper and lower combination chambers are set up to facilitate the combination and separation of the entire sulfate removal device. This not only makes it easier to clean the inside of the device, but also makes it easier to remove the precipitate after the reaction. This avoids the precipitate remaining in the device and affecting the removal of high-concentration sulfate in the subsequent industrial wastewater. The device is equipped with a rotating tube and stirring rod that can be raised, lowered and rotated, so that quicklime can be added while stirring, ensuring that the quicklime can fully react with the high-concentration sulfate in the industrial wastewater.

[0023] 2. A removal detection head is installed, which can determine whether the high concentration of sulfate in industrial wastewater has reacted sufficiently by observing changes in the precipitate. Once the reaction is complete, the addition of quicklime is stopped in time, ensuring efficient removal of high concentrations of sulfate in industrial wastewater while avoiding waste of quicklime.

[0035] Example 2

[0036] Reference Figure 7Based on Example 1, a removal detection head 114 is fixedly installed at the bottom of the lifting plate 106. The removal detection head 114 includes a removal detection module, which is used to control the opening and closing of the ash conveying pump 103 and the switching valve 205. Specifically, at the same time interval, the industrial wastewater in the lower combination chamber 200 is continuously photographed. The photographs are marked as removal photographs, and the removal photographs are used as input data for the removal analysis model. The image labels of the output data of the removal analysis model are obtained, and the image labels of the output data are marked as removal values. The values ​​obtained before the current time are obtained. Given n removal values, sort the removal values ​​according to the shooting time of the corresponding removal photos. Mark the adjacent and earlier removal value after sorting as the next-next removal value and the adjacent and later removal value as the next-next removal value. Calculate the difference between the next-next removal value and the next-next removal value to obtain the removal change value, and mark it as Tb. Set the removal change value threshold to Ez. When the removal change value Tb ≥ the removal change value threshold Ez, no processing is performed. When the removal change value Tb < the removal change value threshold Ez, the removal detection module controls the ash conveying pump 103 to close and controls the switch valve 205 to open. The removal analysis model is obtained through the following steps: Multiple removal photos are acquired, labeled as training images, and image labels are assigned to the training images. The training images are divided into training and validation sets according to a set ratio. A neural network model is constructed, and the neural network model is iteratively trained using the training and validation sets. When the number of iterations exceeds a threshold, the neural network model is considered to have completed training. The trained neural network model is then labeled as the removal analysis model. A higher image label value indicates more precipitate in the removal photo. A removal detection head 114 is installed to determine whether the high-concentration sulfate in the industrial wastewater has reacted sufficiently based on changes in the precipitate. Once the reaction is complete, the addition of quicklime is stopped promptly, ensuring efficient removal of high-concentration sulfate from the industrial wastewater while avoiding waste of quicklime.

[0037] Working principle:

[0038] Step 1: Add quicklime into the quicklime feed hopper 101. The quicklime enters the ash storage box 102 through the quicklime feed hopper 101 for storage. Industrial wastewater enters the lower combined chamber 200 above the sealing plate 203 through the wastewater inlet pipe 201. Then, start the lifting assembly 105. The lifting assembly 105 drives the lifting plate 106 to descend. The lifting plate 106 drives the lifting rod 1051 to extend. Then the lifting plate 106 descends into the lower combined chamber 200. The industrial wastewater is placed between the lifting plate 106 and the sealing plate 203.

[0039] Step 2: Turn on the ash pump 103. The ash pump 103 draws quicklime from the ash storage box 102. The quicklime enters the lower ash hopper 111 through the ash conveying pipe 104. The quicklime in the lower ash hopper 111 enters the rotating tube 107. Start the rotating assembly 108. The rotating assembly 108 drives the first gear 109 to rotate. The first gear 109 meshes and drives the second gear 110 to rotate. The second gear 110 drives the rotating tube 107 to rotate. The rotating tube 107 drives the stirring rod 113 to rotate. The stirring rod 113 stirs the industrial wastewater. During the rotation of the rotating tube 107, the quicklime is thrown out from the ash outlet 112. The quicklime reacts with the high concentration of sulfate in the industrial wastewater. The reaction proceeds, producing precipitate. Once the high-concentration sulfate in the industrial wastewater is removed, the removal detection head 114 controls the ash conveying pump 103 to shut down and the switch valve 205 to open. The industrial wastewater after the removal of the high-concentration sulfate flows into the bottom of the lower combined chamber 200 through the drainage pipe 204. Then, the industrial wastewater flows out through the wastewater outlet pipe 202. Finally, the combined assembly 305 is activated, driving the ball screw 306 to rotate. The ball screw 306 drives the first fixed plate 300 and the second fixed plate 301 to move in opposite directions, thereby causing the upper combined chamber 100 and the lower combined chamber 200 to move in opposite directions. Finally, the precipitate can be removed from the sealing plate 203.
