[0015] Beneficial Effects

[0016] The present invention provides an interception and oil removal device for condensate water of an ethylene device. Compared with the prior art, it has the following beneficial effects:

[0017] (1) By setting up a separation mechanism, the collected condensed water is added into the storage tank for storage. During the storage process, the water and oil are separated into layers due to the different densities of water and oil. The thickness of the oil layer is detected by a sonar detector, and the water and oil are discharged separately through the oil pipes and water pipes set up above and below. By treating the two separately, on the one hand, the overall filtration efficiency is improved, and on the other hand, the front-end filtration pressure is reduced, thereby delaying the service life of the filtration measures and reducing the overall recycling cost.

[0018] (2) By setting up a sub-filtration component and using a driving motor to drive the filter cartridge to rotate, the centrifugal force is used to increase the water pressure during the filtration process to improve the overall filtration efficiency. The liquid water filtered out of the oil layer can be collected through the connection between the two filter tanks to improve the quality of condensed water recovery. The connection between the sleeve and the sliding sleeve not only ensures the stability of the filter cartridge during filtration, but also facilitates the disassembly of the filter cartridge to facilitate the cleaning of impurities.

[0019] (3) By setting a limit unit and utilizing the connection between the fixing strip and the filter cartridge, the filter cartridge can be easily positioned during installation, thereby improving its installation efficiency. At the same time, the filter cartridge can be fixed in place by utilizing the contact between the pin rod and the filter cartridge. The centrifugal force exerted on the pin rod during rotation can enhance the contact effect with the filter cartridge, thereby further improving the stability of the filter cartridge.

[0020] (4) By setting up a fine filtration unit, the atomizer can be used to atomize the filtered condensed water through high-frequency vibration, and the filter element can filter it through the flow of atomized water vapor to further filter out fine impurities carried in the water. At the same time, by reducing the amount of liquid water, larger impurities can be retained inside the liquid tank, thereby further improving the purification effect and efficiency, thereby improving the recovery efficiency and quality of the condensed water.

[0021] (5) By setting up a debris removal component and utilizing the combination of the screw sleeve and the screw ring, the loading and unloading of the magnetic rod is facilitated, and the iron filings in the condensate water can be removed through the magnetic rod. At the same time, the sliding of the folding bar in the slide groove and the inside of the fixed sleeve can push the slip ring to slide along the magnetic rod, so that the iron filings adsorbed by the magnetic rod can be quickly removed, thereby improving the overall filtering processing efficiency.

[0048] After the grease and condensed water enter the two filter cartridges 31 respectively, the driving motor 36 drives the filter cartridge 31 to rotate at a high speed through the support plate 33 and the fixing strip 341, thereby utilizing the centrifugal force and the filtering measures provided inside the filter cartridge 31 to filter the water in the oil and enter the lower filter cartridge 31 through the connecting pipe 4. At the same time, the lower filter cartridge 31 filters out the condensed water through the centrifugal force and corresponding filtering measures and discharges it into the liquid tank 321 through the discharge pipe 11. When all the condensed water is recovered into the liquid tank 321, firstly tighten the nut 312 to make it rise along the bolt 311 and break away from the contact with the connecting plate 310, and then The connecting plate 310 is pushed upward, so that the sliding sleeve 39 moves from the inside of the annular groove 38 to the outside, thereby escaping from the limit of the sleeve 37, and then the connecting rod 346 is pushed into the inside of the fixed strip 341 through the adhesive film 347, so that the abutment plate 344 follows the movement to abut obliquely, so that the ladder plate 345 drives one end of the pin rod 342 to slide into the inside of the fixed strip 341, so that the other end of the pin rod 342 is flush with the surface of the fixed strip 341 to escape from the limit of the filter cartridge 31, and then the filter cartridge 31 is pushed horizontally along the fixed strip 341 to be disassembled, and then the oil and impurities filtered out of the filter cartridge 31 are cleaned, and the installation of the filter cartridge 31 is completed by repeating the above steps in reverse.

[0049] When the filtered condensed water enters the liquid tank 321, it is atomized into water droplets through contact with the atomizing sheet 322. Then, the fan 327 works to make the air inside the liquid tank 321 carry water vapor and enter the inside of the circulation pipe 323. The water vapor is filtered in sequence through the stacked filter elements 324 to filter the fine impurities carried in the water vapor. At the same time, the shaft end of one side of the fan 327 drives the eccentric plate 328 to rotate reciprocally, so that it squeezes the filter element 324 through the filter screen 325 on one side, so that the water vapor adsorbed in the filter element 324 is squeezed out and condensed to form water droplets. The water droplets are discharged from the other end of the circulation pipe 323 through the flow, and the air flows back to the inside of the liquid tank 321 from the other end of the air pipe 326. At the same time, when the condensed water inside the liquid tank 321 is completely evaporated through atomization, the larger volume of impurities contained therein are accumulated in the liquid tank 321. Then, by cleaning the inside of the liquid tank 321 and replacing the filter element 324, it can be used continuously.
