Abstract
Description
Technical Field
[0001] This utility model relates to the field of petrochemical circulating water oil removal technology, specifically a petrochemical circulating water oil removal and purification device. Background Technology
[0002] Petrochemical circulating water is a water circulation system widely used in industries such as petrochemicals, chemicals, pharmaceuticals, and metallurgy. In these industrial production processes, water is recycled to meet various process requirements, such as cooling and heating. During the recycling process, oily substances will inevitably be mixed in due to problems such as pipeline leaks. If the water is directly replaced, it will cause a lot of waste of resources. Therefore, it is necessary to regularly remove oil from the cooling water.
[0003] The petrochemical circulating water oil removal and purification device disclosed in CN213924284U has a relatively low oil content in the water after treatment in the primary tank, which can better ensure the effect of subsequent fine filtration. At the same time, the primary tank of this application avoids the re-mixing of oil and water after separation, improves the thoroughness of oil-water separation, improves the oil filtration effect, and strengthens the recycling of resources.
[0004] This petrochemical circulating water oil removal and purification device can treat petrochemical circulating water through its filter tank. However, the device does not have a structure for neutralizing and purifying the petrochemical circulating water. Relying solely on filtration, it can only handle some suspended oil or larger oil droplets, and its removal effect on emulsified oil and dissolved oil is limited. Therefore, it needs improvement.

[0029] This utility model provides the following technical solution: Example 1
[0030] Please see Figure 1-6 This utility model provides a technical solution: a petrochemical circulating water oil removal and purification device, including a base 1, a stirring tank 2 fixedly connected to the top left side of the base 1, a stirring and filtering mechanism 3 provided at the back end of the stirring tank 2, and an auxiliary mechanism 4 provided on the top right side of the base 1.
[0031] The stirring and filtering mechanism 3 includes a stirring component 31 and a filtering component 32. The stirring component 31 is located at the back end of the stirring tank 2, and the filtering component 32 is located at the top center of the base 1.

[0035] Please see Figure 1-6 Furthermore, based on Embodiment 1, the filter assembly 32 further includes a fixing frame 325, which is fixedly connected to the top center of the base 1. A filter box 324 is fixedly connected to the top of the fixing frame 325. A filter plate 326 is slidably connected inside the filter box 324.

[0036] Furthermore, there are four bolts 327, which are threaded onto the inner side of the sealing plate 323. The bolts 327 can be used to fix the sealing plate 323, making the filter plate 326 more stable during use. Example 3
[0037] Please see Figure 1-6Furthermore, based on Embodiment 1, the auxiliary mechanism 4 includes an oil removal tank 42, which is fixedly connected to the top right side of the base 1. A water outlet plate 43 is fixedly connected to the top of the oil removal tank 42, and a connecting pipe 44 is fixedly connected to the top of the water outlet plate 43. The connecting pipe 44 is fixedly connected to the right side of the filter box 324, and an activated carbon plate 41 is fixedly connected to the inside of the filter box 324. A water outlet pipe 46 is fixedly connected to the right side of the oil removal tank 42, and a second water pump 45 is fixedly connected to the outside of the water outlet pipe 46. The second water pump 45 is fixedly connected to the right side of the oil removal tank 42.
[0038] Furthermore, a fixing hole corresponding to the position of the connecting pipe 44 is provided at the top of the oil removal tank 42, and the outer wall of the connecting pipe 44 is in contact with the inner wall of the fixing hole. Through the fixing hole, the connecting pipe 44 can be inserted into the oil removal tank 42, so that the filtered petrochemical circulating water can be sprayed out through the water outlet plate 43.
[0039] In actual operation, when this device is used, petrochemical circulating water is introduced into the mixing tank 2, and the degreasing agent is poured into the mixing tank 2. The drive motor 317 is turned on by the PLC controller, so that the drive motor 317 drives the mixing plate 314 to rotate through the rotating shaft 315, so that the mixing plate 314 can stir the petrochemical circulating water in the mixing tank 2. After stirring, the petrochemical circulating water is allowed to stand, and the solid waste can fall to the top of the fixed plate 312. The first water pump 321 is turned on by the PLC controller, so that the first water pump 321 can introduce the degreased petrochemical circulating water in the mixing tank 2 into the transmission pipe 322, so that the petrochemical circulating water can enter the filter box 324 and be filtered by the filter plate 326.
[0040] The filtered petrochemical circulating water is transmitted to the inside of the water outlet plate 43 through the connecting pipe 44. The petrochemical circulating water is sprayed out through the water outlet plate 43. The sprayed petrochemical circulating water undergoes secondary oil removal through the activated carbon plate 41. The oil-removed petrochemical circulating water falls to the bottom of the oil removal tank 42. The second water pump 45 is turned on to discharge the oil-removed petrochemical circulating water from the bottom of the oil removal tank 42 for recycling.
[0041] After the petrochemical circulating water inside the mixing tank 2 is discharged, the PLC controller turns on the rotating motor 318, which drives the threaded rod 3191 to rotate. The threaded rod 3191 drives the connecting plate 311 to move upward through the threaded plate 3192. The connecting plate 311 drives the sealing cover 316 to move upward, and the sealing cover 316 can drive the fixed plate 312 to move upward through the linkage plate 313. The fixed plate 312 moves to the top of the mixing tank 2, making it convenient for the staff to clean the solid waste remaining on the top of the fixed plate 312.
[0042] When the filter plate 326 inside the filter box 324 becomes clogged, the operator rotates the bolt 327 to move the bolt 327 away from the inside of the filter box 324, making it easier for the operator to disassemble the sealing plate 323 and the filter plate 326, and making it easier for the operator to clean the filter plate 326, so that the device can better filter oil from petrochemical circulating water.
