Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically a wastewater treatment device used in petrochemical production processes. Background Technology

[0002] Wastewater treatment equipment used in petrochemical production processes is diverse, aiming to effectively remove organic matter, suspended solids, oils, and other pollutants from wastewater to meet environmental protection requirements and reuse standards. In treating wastewater from petrochemical production processes, large particulate impurities are typically filtered through a screen first, followed by flocculation and sedimentation, then secondary filtration to remove oily substances. Finally, the wastewater is passed through an activated carbon system, where it contacts the activated carbon to absorb harmful substances. However, the following drawbacks still exist:

[0003] During the process of sewage flowing through activated carbon, some sewage does not come into contact with the activated carbon. The probability of sewage coming into contact with activated carbon is low, resulting in poor adsorption of harmful substances. Utility Model Content

[0004] In view of the above situation and to overcome the shortcomings of the prior art, this utility model provides a wastewater treatment device for petrochemical production processes, which effectively solves the problems of low contact probability between wastewater and activated carbon and poor adsorption effect on harmful substances.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wastewater treatment device for petrochemical production processes, comprising a lower treatment tank, an upper treatment tank above the lower treatment tank, a support frame fixedly installed between the lower treatment tank and the upper treatment tank, a sedimentation and filtration assembly installed inside the upper treatment tank, and an impurity adsorption assembly installed inside the lower treatment tank.

[0006] The impurity adsorption assembly includes a sliding frame located inside the lower treatment box. The sliding frame has mounting slots equidistantly spaced on it. A treatment cylinder is installed inside the mounting slot. The inside of the treatment cylinder is used to hold activated carbon. A fixing sleeve is installed at the top of the treatment cylinder. The bottom wall of the fixing sleeve is in contact with the top wall of the sliding frame.

[0007] Preferably, the outer wall of the treatment cylinder is provided with uniformly distributed connecting holes, which are connected to the inner cavity of the treatment cylinder, allowing wastewater to come into contact with the activated carbon inside the treatment cylinder through the connecting holes.

[0008] Preferably, a positioning rod is installed at an equal angle on the top of the fixing sleeve, and a top cover is provided above the fixing sleeve. A positioning groove is opened at an equal angle on the top cover, and the positioning rod is inserted into the positioning groove.

[0009] Preferably, the two ends of the sliding frame are slidably installed inside the two sliding grooves, which are symmetrically opened on the inner wall of the lower processing box. A screw is rotatably installed inside one of the sliding grooves. The screw is threadedly connected to the sliding frame, and one end of the screw is fixedly connected to the output shaft of the motor. The motor is fixedly installed on the lower processing box.

[0010] Preferably, the sedimentation filtration assembly includes a drain pipe fixedly installed at the bottom of the upper treatment box, the drain pipe being connected to the upper treatment box, and a baffle being movably installed on the inner side of the upper treatment box. When the bottom wall of the baffle is in close contact with the inner bottom wall of the upper treatment box, the baffle seals the top of the drain pipe, and filter holes are evenly provided on the baffle.

[0011] Preferably, vertical rods are symmetrically installed on the top of the baffle, and horizontal plates are fixedly installed on the top of the vertical rods. Cylinders are symmetrically arranged on both sides of the upper processing box, and the output ends of the cylinders are fixedly connected to the horizontal plates.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1, by Figure 1-4 The present invention relates to a wastewater treatment device for petrochemical production processes, comprising a lower treatment tank 1, an upper treatment tank 2 above the lower treatment tank 1, a support frame 3 fixedly installed between the lower treatment tank 1 and the upper treatment tank 2, a sedimentation and filtration assembly 4 installed inside the upper treatment tank 2, and an impurity adsorption assembly 5 installed inside the lower treatment tank 1.

[0025] The impurity adsorption assembly 5 includes a sliding frame 502 located inside the lower treatment tank 1. The sliding frame 502 has equidistant mounting grooves 505. A treatment cylinder 506 is installed inside the mounting grooves 505, and the interior of the treatment cylinder 506 is used to hold activated carbon. A fixing sleeve 507 is installed at the top of the treatment cylinder 506, and the bottom wall of the fixing sleeve 507 contacts the top wall of the sliding frame 502. Uniformly distributed connecting holes 508 are formed on the outer wall of the treatment cylinder 506, communicating with the inner cavity of the treatment cylinder 506. Wastewater contacts the activated carbon inside the treatment cylinder 506 through the connecting holes 508. A positioning rod 509 is installed at equal angles at the top of the fixing sleeve 507. A top cover 510 is located above the fixing sleeve 507, and positioning rods 509 are formed at equal angles on the top cover 510. The positioning rod 509 is inserted into the positioning groove. The two ends of the sliding frame 502 are slidably installed inside the two sliding grooves 501. The sliding grooves 501 are symmetrically opened on the inner wall of the lower treatment box 1. A screw 503 is rotatably installed inside one of the sliding grooves 501. The screw 503 is threadedly connected to the sliding frame 502. One end of the screw 503 is fixedly connected to the output shaft of the motor 504. The motor 504 is fixedly installed on the lower treatment box 1. The top of the treatment cylinder 506 is provided with a top cover 510 for easy storage of activated carbon. When replacing, the treatment cylinder 506 is taken out from the installation groove 505, and then the top cover 510 is removed. The activated carbon in the treatment cylinder 506 is poured out and replaced with new activated carbon, which facilitates the replacement of activated carbon and facilitates subsequent adsorption.

[0026] The sedimentation filter assembly 4 includes a drain pipe 401 fixedly installed at the bottom of the upper treatment box 2, the drain pipe 401 being connected to the upper treatment box 2. A baffle 402 is movably installed on the inner side of the upper treatment box 2. When the bottom wall of the baffle 402 is in close contact with the inner bottom wall of the upper treatment box 2, the baffle 402 seals the top of the drain pipe 401. Filter holes 403 are evenly distributed on the baffle 402. Vertical rods 404 are symmetrically installed on the top of the baffle 402. A horizontal plate 405 is fixedly installed on the top of the vertical rods 404. Cylinders 406 are symmetrically arranged on both sides of the upper treatment box 2. The output end is fixedly connected to the horizontal plate 405. Mounting brackets 407 are symmetrically installed on both sides of the upper treatment box 2. The cylinder 406 is installed on the mounting bracket 407. A drain pipe 401 is installed at the bottom of the upper treatment box 2. A baffle 402 is provided inside the upper treatment box 2. When the baffle 402 is in close contact with the bottom wall of the upper treatment box 2, it can seal the top of the drain pipe 401, which facilitates the flocculation and sedimentation of sewage. After the baffle 402 is lifted, water can enter the lower treatment box 1 from the filter hole 403 and the drain pipe 401, which facilitates the filtration of sewage and subsequent adsorption treatment.

[0027] Working principle: During operation, first ensure that the bottom wall of the baffle 402 is in close contact with the inner bottom wall of the upper treatment tank 2. The baffle 402 seals the top of the drain pipe 401. The sewage to be treated is put into the upper treatment tank 2. Flocculant and treatment agent are added into the upper treatment tank 2. After the sewage reacts with the flocculant and treatment agent and settles, the sediment in the sewage settles to the top of the baffle 402. Then, the output end of the control cylinder 406 extends and pushes the baffle 402 to move upward. Since the sediment is blocked by the baffle 402, the water that has removed the sediment enters below the baffle 402 through the filter hole 403 and then enters the lower treatment tank 1 through the drain pipe 401.

[0028] After the sewage enters the lower treatment tank 1, the harmful substances in the sewage are adsorbed. The motor 504 is turned on, which makes the screw 503 rotate back and forth, driving the sliding frame 502 to move laterally back and forth inside the lower treatment tank 1. The treatment cylinder 506 is filled with activated carbon. When the treatment cylinder 506 moves with the sliding frame 502, the sewage continuously comes into contact with the activated carbon through the connecting hole 508, so that the activated carbon adsorbs the harmful substances in the sewage.

[0029] When the activated carbon needs to be replaced after a long period of adsorption, the treatment cylinder 506 is pulled out from the installation slot 505, and then the top cover 510 is opened to pour out the activated carbon in the treatment cylinder 506 and then fill it with new activated carbon for easy replacement.
