Description

Technical Field

[0001] The invention belongs to the technical field of petrochemical chemical waste liquid treatment, and in particular relates to a purification treatment device for petrochemical chemical waste liquid. Background Art

[0002] Petrochemical waste liquid is mainly produced in the process of petroleum refining and chemical production. In the process of oil refining, crude oil undergoes a series of physical and chemical treatment steps such as distillation, cracking, and reforming, which will produce wastewater containing pollutants such as oil, sulfur, phenol, cyanide, COD, etc. These wastewaters come from multiple links such as oil-water separation, equipment cleaning, and condensate discharge. They are usually treated harmlessly through three stages: pretreatment, main treatment, and deep treatment. The pretreatment mainly uses flocculants to form precipitation in the wastewater to remove suspended solids and large particles in the wastewater.

[0003] In the prior art, considering that chemical waste liquid is usually harmful to the human body, in order to reduce the contact time with the chemical waste liquid, the operator will put the chemical waste liquid and flocculant into the treatment equipment together. However, this makes it difficult for the operator to control the amount of flocculant input. Excessive flocculant may cause excessive agglomeration of particulate matter and form overly large agglomerates. These agglomerates will exceed the processing capacity of the sedimentation equipment, which will be detrimental to the treatment of the waste liquid. Summary of the invention

At the same time, the operator observes the agglomeration of the waste liquid inside the treatment box through the observation window and adjusts the extended length of the protrusion to change the dripping dosage to achieve a reasonable agglomeration effect. During the process, the spiral plate drives the waste liquid at the bottom of the treatment box to flow to the top, thereby accelerating the mixing efficiency of the flocculant and the chemical waste liquid. When the suspended particles and colloids in the waste liquid are fully flocculated to form larger agglomerates, the waterproof push rod pushes the sealing plate to seal the exchange hole, and at the same time adjusts the movable plate up and down to separate the agglomeration layers on the upper and lower sides. At this time, when extracting it in layers, the interference with other liquid layers can be greatly reduced to avoid the agglomerated particles from being re-mixed into the waste liquid. When the extraction is completed, the cleaning brush can clean the contact surface between the arc groove and the agglomeration to prevent it from being blocked by particles.

DETAILED DESCRIPTION

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-Figure 6 The purification treatment equipment for petrochemical chemical waste liquid shown in the figure includes a treatment box 1, and an observation window 2 is arranged on one side of the outer wall of the treatment box 1, so that the interior of the treatment box 1 can be observed to assist the operator in judging the agglomeration situation inside, and then judging whether flocculant needs to be added. The top of the treatment box 1 is fixedly connected to a first installation frame 3, and the top of the first installation frame 3 is fixedly installed with a first motor 4, and the output end of the first motor 4 is fixedly connected to a first rotating shaft 5, and the first rotating shaft 5 is inserted and rotatably connected to the interior of the treatment box 1, and a second rotating shaft 7 is inserted and rotatably connected to one side of the first installation frame 3 through a mounting plate, and a bevel gear set 6 is arranged between the second rotating shaft 7 and the first rotating shaft 5, and a cam is arranged on the outer wall of the second rotating shaft 7, and the top of the treatment box 1 is also fixedly connected to a second installation frame 11. A double-plate plug rod 9 is inserted and rotatably connected to the top of the second mounting frame 11, and an extrusion cylinder 10 is arranged on the inner side of the second mounting frame 11. A nozzle is fixedly connected to the bottom of the extrusion cylinder 10, and the nozzle is fixedly connected and inserted into the interior of the treatment box 1. The extrusion cylinder 10 is arranged as an elastic structure. Through the connection of the bevel gear set 6, the cam can be driven to rotate after the first motor 4 is started. The protruding part of the cam is constantly in contact with the double-plate plug rod 9 and presses the extrusion cylinder 10, thereby squeezing the internal flocculant to drip into the interior of the treatment box 1, and the extrusion cylinder 10 will restore its own shape and push the double-plate plug rod 9 upward to reset it. Through this design, the extrusion cylinder 10 can repeatedly drip flocculant into the interior of the treatment box 1 in a quantitative manner, which can facilitate the user to control the dosage and prevent the formation of excessive agglomeration.

[0023] The cam includes a turntable 8 fixedly connected to the outer wall of the second rotating shaft 7, the outer wall of the turntable 8 is provided with an extension groove 32, and a protrusion 31 is inserted and slidably connected inside the extension groove 32, and a rod-type shifting plate 33 is fixedly connected to one side edge of the protrusion 31, and the rod-type shifting plate 33 is slidably connected and extends to the outer side of the turntable 8, and elastic sheets 35 are fixedly connected to both sides of the outer wall of the rod-type shifting plate 33, and a pair of uniformly distributed positioning grooves 34 are provided on one side of the outer wall of the turntable 8, and the positioning grooves 34 cooperate with the elastic sheets 35, and the elastic sheets 35 on both sides are shifted to make them disengage from the inside of the positioning grooves 34, that is, the protrusion 31 can be swung up and down to adjust its extended length. Through this design, the extended length of the protrusion 31 is adjusted to adjust the compression length of the extrusion cylinder 10, so that the extruded dosage can be controlled, and at the same time, when the protrusion 31 is completely received in the extension groove 32, the extrusion cylinder 10 can be prevented from being squeezed, and the flocculant will not drip into the inside of the processing box 1, which is convenient for the staff to control the amount of flocculant dripping.

[0024] A connecting pipe 13 is inserted and fixedly connected to the outer wall of the extrusion cylinder 10, and a feeding hopper 12 is fixedly connected to one side of the outer wall of the first mounting frame 3 through a mounting plate, and the feeding hopper 12 is communicated with the connecting pipe 13. Through this design, flocculant is fed and replenished into the interior of the extrusion cylinder 10 through the feeding hopper 12. At the same time, when the feeding hopper 12 is closed, the flocculant can be prevented from entering the interior of the processing box 1 through the nozzle on the extrusion cylinder 10.

[0025] The interior of the processing box 1 is provided with a partition assembly, a pair of partition assemblies arranged up and down and facing each other, the partition assembly includes a plug rod 20 that is inserted and rotatably connected to the four corners of the outer wall of the processing box 1, the outer wall of the plug rod 20 is sleeved with a slide-out tube 21, the two ends of one of the plug rods 20 are respectively fixedly connected with a threaded block 30 and a second motor 14, the threaded block 30 is screwed inside the slide-out tube 21, the second motor 14 is fixedly installed on the outer wall of the processing box 1 through a mounting frame, the outer wall of the slide-out tube 21 is fixedly connected with a movable plate 22, and the movable plate 22 is slidably connected to the processing box 1. Inside the box 1, arc grooves 23 are provided on both sides of the outer wall of the movable plate 22, and the outer wall of the arc groove 23 is provided with evenly distributed communication holes 24. The movable plate 22 can separate the agglomerated particles to prevent them from being re-mixed into the waste liquid when being pumped. The second motor 14 drives the threaded block 30 to rotate, thereby driving the slide-out tube 21 to move up and down along the outside of the insertion rod 20, and then synchronously drives the movable plate 22 to slide up and down along the outer wall of the partition tube 18, thereby adjusting the upper and lower positions of the movable plate 22, so that agglomerates of different thicknesses can be adapted and separated.

[0026] Waterproof push rods 25 are fixedly installed on both sides of the outer wall of the movable plate 22 through a mounting frame, and a sealing plate 26 is fixedly connected to the output end of the waterproof push rod 25. A first liquid outlet pipe 15 is inserted and fixedly connected to one side of the outer wall of the treatment box 1, and a third liquid outlet pipe 17 and a second liquid outlet pipe 16 are inserted and fixedly connected to one side of the inner wall of the treatment box 1 from top to bottom. When the liquid inside the treatment box 1 is respectively extracted through the second liquid outlet pipe 16, the third liquid outlet pipe 17 and the first liquid outlet pipe 15, the waterproof push rod 25 drives the sealing plate 26 to press against the movable plate 22 and form a seal on the arc groove 23 to prevent the liquid from flowing through the exchange hole 24. At this time, when layered extraction is performed, it can avoid affecting other layers of chemical waste liquid.

[0027] The interior of the treatment box 1 is fixedly connected to the partition cylinder 18 through a mounting frame, and the movable plate 22 is inserted and slidably connected to the outer wall of the partition cylinder 18, a spiral plate 27 is fixedly connected to the outer wall of the first rotating rod 5, and a pair of holed connecting rings 28 are also fixedly connected to the outer wall of the double-plate inserting rod 9, and the two holed connecting rings 28 are respectively located on the upper and lower sides of the partition cylinder 18, and a cleaning brush 29 is fixedly connected to the outer wall of the holed connecting ring 28, and the cleaning brush 29 is set as a disc structure. The first rotating shaft 5 drives the spiral plate 27 to rotate inside the partition cylinder 18, so that the liquid at the bottom is drawn to the upper part, thereby enhancing the mixing effect of the flocculant and the chemical waste liquid. At the same time, the rotating cleaning brush 29 can also clean the arc groove 23 to prevent it from being blocked by particles.

[0028] The outer wall edges of the partition 18 are both provided with evenly distributed liquid holes 19. Through this design, the interior of the partition 18 is connected with the processing box 1. When the liquid is extracted from the processing box 1, the liquid filling the interior of the partition 18 will also be extracted.

[0029] Working principle:

[0030] When in use, the double-plate plug rod 9 periodically squeezes the extrusion cylinder 10 to drip a quantitative amount of flocculant into the interior of the treatment box 1, so that the flocculant can be stably supplied to the interior of the treatment box 1. At the same time, the operator observes the agglomeration of the waste liquid in the treatment box 1 through the observation window 2 and adjusts the extension length of the protrusion 31, so as to change the dripping dosage to achieve a reasonable agglomeration effect. During the process, the spiral plate 27 drives the waste liquid at the bottom of the treatment box 1 to flow to the top, thereby accelerating the mixing efficiency of the flocculant and the chemical waste liquid. When the suspended particles and colloids in the waste liquid are fully flocculated to form larger agglomerates, the waterproof push rod 25 pushes the sealing plate 26 to seal the exchange hole 24, and at the same time, the movable plate 22 is adjusted up and down to separate the agglomeration layers on the upper and lower sides. At this time, when it is extracted in layers, the interference with other liquid layers can be greatly reduced to avoid the particles after agglomeration from being mixed into the waste liquid again. When the extraction is completed, the cleaning brush 29 can clean the contact surface between the arc groove 23 and the agglomeration to prevent it from being blocked by particles.
