Description

Technical Field

[0001] The invention relates to an environmental protection treatment device, in particular to an integrated environmental protection treatment device for comprehensive waste liquid of oily sludge. Background Art

[0002] Oily sludge refers to sludge mixed with crude oil, various refined oils, residual oil and other heavy oils. This sludge does not exist originally in nature, but is a complex mixture formed by the leakage of crude oil and refined oil into the environment due to improper operation, equipment aging, damage or corrosion during oil field exploitation, petroleum refining, transportation, use and storage, and mixed with soil, water and other media.

[0003] Since oily sludge is very harmful to the environment, it is necessary to treat the oily sludge in an environmentally friendly manner. For example, CN118479703B involves an oily sludge pyrolysis treatment device, which includes an outer cylinder and an inner cylinder, and also includes: a heating module, which is fixedly mounted on the inner wall of the outer cylinder and fits the inner cylinder; a support portion, which includes a base and a motor; a drive differential portion, which includes a connecting gear ring fixedly mounted on a support column; a gas phase extraction portion, which includes a fixed ring fixedly mounted on the inner wall of the outer cylinder; and a discharge portion, which includes an oil discharge pipe fixedly connected to the bottom of the outer cylinder. When the oily sludge pyrolysis treatment device performs pyrolysis treatment on the oily sludge, the liquid oil therein can be directly separated and discharged intermittently, and the oil gas can be quickly extracted for condensation separation, thereby improving the treatment efficiency and the safety of the device. The problem is that the solid phase matter in the oily sludge is clay and a small amount of minerals, and the whole is a colloid with great viscosity. When the oily sludge is pyrolyzed, as the pyrolysis proceeds, a temperature gradient phenomenon occurs in the heat transfer process, that is, when the outer surface temperature has reached the set temperature, but the center temperature has not reached it, it is difficult to remove the adsorbed oil deep in the colloid, resulting in this type of device being difficult to completely remove the oil when treating the oily sludge waste liquid, and the oil removal effect is poor.

[0039] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0041] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0042] Large amounts of oily sludge will cause the petroleum substances in the soil to exceed the standard, resulting in soil compaction and vegetation destruction; at the same time, the migration and infiltration of petroleum hydrocarbons in the soil will pollute groundwater, and the open-air storage of oily sludge will cause serious waste of resources, pollute the soil and atmosphere, and cause permanent damage to the ecosystem.

[0043] Existing pyrolysis treatment devices pyrolyze oily sludge to directly separate and discharge the liquid oil therein, and can quickly extract the oil and gas for condensation separation. However, when pyrolyzing the oily sludge, as the pyrolysis proceeds, a temperature gradient phenomenon occurs in the heat transfer process, that is, when the outer surface temperature has reached the set temperature, but the center temperature has not reached it, it is difficult to remove the adsorbed oil deep in the colloid, resulting in difficulty in completely removing the oil when such devices treat oily sludge wastewater.

[0044] Therefore, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the purpose of this embodiment is to provide an integrated waste liquid environmental protection treatment device for oily sludge, including a treatment tank 1 and a sludge treatment component arranged in the treatment tank 1;

[0045] The treatment kettle 1 includes a body 11 and a mixing body 12 and a control and discharge body 13 arranged in the body 11. The mixing body 12 includes a motor 121 fixed on the body 11 and a lifting stirring member 123 located in the treatment chamber 113. The motor 121 is connected to the lifting stirring member 123 through a screw 122. The lifting stirring member 123 is used to reciprocate up and down in the body 11 to accelerate the mixing of the reagent and the waste liquid. The control and discharge body 13 is used to discharge the treatment product.

[0046] The sludge treatment component includes an oil removal body 2 and a mud scraping body 3. The oil removal body 2 and the mud scraping body 3 are both located in the mixing body 12. The mud scraping body 3 is located below the oil removal body 2. The oil removal body 2 is used to squeeze the sludge for oil removal, and the mud scraping body 3 is used to drive the movement of the sludge. The comprehensive waste liquid containing oily sludge and the agent are put into the body 11 together. The lifting stirring member 123 moves up and down along the inner wall of the body 11 to drive the flow of the liquid, thereby helping the mixing reaction of the agent and the waste liquid. During the treatment process, the oily sludge in the waste liquid will settle to the bottom. At the bottom of the main body 11, when the lifting and stirring member 123 descends to the bottom along the inner wall of the main body 11, it will drive the de-oiling body 2 and the mud scraping body 3 to move and block the bottom of the lifting and stirring member 123, so that the bottom of the lifting and stirring member 123 can squeeze the oily sludge and de-oil the sludge. The removed oil is then mixed with the reagent to react to achieve environmentally friendly treatment of the waste liquid. When the contents of the main body 11 are discharged, the lifting and stirring member 123 drives the mud scraping body 3 to move through the de-oiling body 2 to discharge the sludge accumulated at the bottom of the main body 11.

[0047] The above structure is disclosed as follows:

[0048] like Figure 3 , Figure 4 , Figure 5 As shown, the top of the body 11 is connected to a feeding pipe 111 for feeding, and a pipe top frame 112 is provided on the top of the feeding pipe 111. A processing chamber 113 for treating waste liquid is provided in the body 11, and an intracavity bracket 114 for guiding the movement of the mixing body 12 is symmetrically provided on the inner wall of the processing chamber 113. The motor 121 is fixed on the pipe top frame 112, and the lifting stirring member 123 includes a stirring plate 1231 located in the processing chamber 113. One end of the bottom of the lead screw 122 passes through the middle of the stirring plate 1231 and is reciprocatingly threadedly connected to the stirring plate 1231. Slots 1232 are provided on both sides of the stirring plate 1231. The intracavity bracket 114 is stuck in the slot 1232. The stirring plate 1231 and the inner wall of the processing chamber 113 are connected through the intracavity bracket 114. The bracket 114 and the slot 1232 are connected by sliding up and down. A plurality of openings 1233 for liquid to pass through are opened on the stirring plate 1231. The comprehensive waste liquid and flocculants, adsorbents and other chemicals are fed together and enter the treatment chamber 113 through the feeding pipe 111. Driven by the motor 121, the stirring plate 1231 reciprocates up and down along the inner wall of the treatment chamber 113. When the stirring plate 1231 is active, the liquid in the treatment chamber 113 passes through the stirring plate 1231 through the openings 1233, that is, the movement of the stirring plate 1231 drives the liquid in the treatment chamber 113 to flow, and then the flow of the liquid enables the chemicals to be fully mixed with the waste liquid, thereby ensuring the treatment effect of the waste liquid.

[0049] Taking into account that the stirring plate 1231 will cause the liquid in the processing chamber 113 to splash out from the feeding pipe 111 when it makes an up and down reciprocating motion, in order to avoid this situation, a hollow floating plate 115 is provided in the processing chamber 113, and the hollow floating plate 115 is located above the stirring plate 1231. Both ends of the hollow floating plate 115 are slidably connected to the cavity bracket 114 up and down. The hollow floating plate 115 is a disc structure with a diameter larger than the inner diameter of the feeding pipe 111. By providing the hollow floating plate 115, when feeding, the hollow floating plate 115 will rise as the liquid level in the processing chamber 113 rises, until the hollow floating plate 115 is stuck at the bottom end of the connection between the feeding pipe 111 and the body 11, blocking the bottom of the feeding pipe 111, so that when the stirring plate 1231 makes an up and down reciprocating motion, the liquid in the processing chamber 113 will not splash out from the feeding pipe 111, thereby ensuring the treatment effect of the waste liquid.

[0050] When the stirring plate 1231 reciprocates up and down to promote the mixing of the reagent and the waste liquid, the oily sludge in the waste liquid and the sediment produced by the reaction between the waste liquid and the reagent will pass through the plate opening 1233 of the stirring plate 1231 and then fall to the bottom of the processing chamber 113 and accumulate. In order to achieve effective oil removal treatment of the sediment, Figure 5 , Figure 6 , Figure 7 As shown, the de-oiling body 2 includes baffles 21 arranged in pairs in the stirring disk 1231, and a contact wedge 22 is arranged at one end of the baffle 21 away from the screw 122, and the contact wedge 22 is located in the slot 1232. The intracavity support 114 is provided with a protrusion protruding toward the center of the processing chamber 113 near the bottom end of the processing chamber 113, and a first spring is arranged on the end of the baffle 21 away from the contact wedge 22. The baffle 21 is connected to the inner wall of the stirring disk 1231 through the arranged first spring, and a first plate opening 23 and a second plate opening 24 connected to the disk opening 1233 are opened on the baffle 21.

[0051] The diameter of the first plate opening 23 matches the diameter of the plate opening 1233, and the second plate opening 24 is a small hole that limits the passage of liquid. When the stirring plate 1231 reciprocates up and down along the intracavitary support 114, the end of the contact wedge block 22 continues to contact the surface of the intracavitary support 114. Fig.10The middle arrow a indicates the moving direction of the stirring plate 1231. Under normal circumstances, the first plate opening 23 is connected to the bottom of the plate opening 1233. When the stirring plate 1231 moves, the liquid can flow through the plate opening 1233 and the first plate opening 23. When the stirring plate 1231 moves down to the bottom end of the processing chamber 113 close to the sediment, the end of the contact wedge 22 just contacts the protrusion of the cavity support 114, and under the action of the inclined surface of the protrusion, the baffle 21 overcomes the elastic force of the first spring and moves away from the cavity support 114 until the second plate opening 24 is connected to the bottom of the plate opening 1233. At this time, the bottom of the stirring plate 1231 contacts the sediment and squeezes the sediment, so that the oil-containing liquid in the sediment is squeezed out and reaches the position above the stirring plate 1231 in the processing chamber 113 through the second plate opening 24 and the plate opening 1233, and can be fully mixed with the reagent in the liquid to remove oil. When the stirring plate 1231 moves up, the end of the contact wedge block 22 does not contact the protrusion. Under the action of the first spring, the baffle 21 is reset. At this time, the first plate opening 23 is connected to the bottom of the plate opening 1233, as shown in FIG. Fig.10 The middle arrow b shows the moving direction of the baffle 21 during the movement of the impeller 1231. For the sediment, the sediment will be squeezed once in each up and down movement cycle of the impeller 1231, so that the oil-containing substances in the sediment are fully removed, thereby achieving effective oil removal of the oily sludge waste liquid.

[0052] After a certain period of treatment, the liquid in the treatment chamber 113 that has been degreased needs to be discharged. Fig. 9As shown, the bottom of the body 11 is connected to a discharge pipe 116 for discharging liquid, the bottom of the processing chamber 113 is connected to a discharge chamber 117, the bottom end of the discharge chamber 117 is connected to the top of the discharge pipe 116, and a drainage groove 118 is symmetrically opened on the inner wall of the body 11. The top of the drainage groove 118 is connected to the side wall of the processing chamber 113 near the bottom, and the bottom end of the drainage groove 118 is connected to the discharge chamber 117. A filter screen 1131 is provided at the connection between the processing chamber 113 and the drainage groove 118. The control and discharge body 13 includes a control shaft 131 and a plug 132 located in the discharge chamber 117. The bottom end of the plug 132 is threadedly connected to the top end of the control shaft 131, and the bottom end of the control shaft 131 is connected to a turning handle 133. One end of the turning handle 133 passes through the discharge pipe 116, and the top of the plug 132 blocks the processing chamber 1 13, a discharge port at the bottom of the plug 132, second connecting frames 134 are provided at both ends of the plug 132, and an inner plate 135 is provided on the top of the second connecting frame 134, which is located on the side of the filter 1131 away from the processing chamber 113. After the degreasing treatment of the waste liquid is completed, the control shaft 131 is driven to rotate by turning the handle 133, and the control shaft 131 drives the plug 132 downward away from the discharge port at the bottom of the processing chamber 113, and when the plug 132 moves downward, it will drive the inner plate 135 to move downward synchronously through the second connecting frame 134, so that the liquid in the processing chamber 113 can enter the discharge chamber 117 through the discharge port of the processing chamber 113, and enter the drainage trough 118 through the filter 1131, and then enter the discharge chamber 117 from the drainage trough 118, so that the liquid can be discharged through the discharge pipe 116.

[0053] It is worth noting that when the liquid is discharged, some sediments will adhere to the bottom of the processing chamber 113 and cannot be discharged through the discharge port. In order to prevent the sediments from accumulating in the processing chamber 113, the attached sediments need to be processed, such as Figure 8 , Fig.10As shown in the figure, the bottom of the processing chamber 113 is concave downward, and the discharge port at the bottom of the processing chamber 113 is located at the lowest point. The mud scraping body 3 includes a pressure structure arranged on the stirring plate 1231 and a mud scraping plate 31 horizontally slidably connected to the bottom of the stirring plate 1231. The pressure structure is used to control the synchronous movement of the baffle 21 and the mud scraping plate 31. When discharging the liquid, the liquid level in the processing chamber 113 is lowered, so that the hollow floating plate 115 moves down and presses on the stirring plate 1231. The pressure structure arranged on the stirring plate 1231 is pressed down by the hollow floating plate 115, and the pressure structure fixes the baffle 21 and the mud scraping plate 31. When the agitator 1231 moves down to the bottom end of the processing chamber 113 and is close to the sediment, the end of the contact wedge 22 contacts the protrusion of the intracavity bracket 114, and under the action of the inclined surface of the protrusion, the baffle 21 overcomes the first spring force and moves away from the intracavity bracket 114, thereby driving the bottom mud scraper plate 31 to move synchronously, contacting the sediment and driving the sediment to move toward the discharge port. Driven by the mud scraper plate 31, the sediment can slide down along the concave surface of the bottom of the processing chamber 113 to the discharge port, thereby realizing the treatment of the sediment and avoiding the sediment from accumulating in the processing chamber 113.

[0054] The above-mentioned pressing structure is specifically disclosed as follows:

[0055] The pressing structure includes a disk top ring 1234 plugged with the top of the stirring disk 1231, a second spring is arranged at the bottom of the disk top ring 1234, and the disk top ring 1234 is connected to the top of the stirring disk 1231 through the second spring arranged at the bottom, and one end of the disk top ring 1234 is connected to the first connecting frame 1235, and a slider 1236 is arranged at the bottom of the first connecting frame 1235. A movable block 221 that moves up and down is arranged in the middle of the contact wedge block 22, and the slider 1236 is horizontally slidably connected to the top of the movable block 221, and an upper hook claw 32 is arranged at a corresponding position on the upper surface of the mud scraping plate 31. When the liquid in the processing chamber 113 is discharged, as the liquid level decreases, the hollow floating plate 115 moves down. The top ring 1234 of the disc 1234 is pressed against the surface of the agitator 1231, so that the top ring 1234 overcomes the elastic force of the second spring and moves downward, driving the first connecting frame 1235 and then driving the slider 1236 to move downward, and the slider 1236 drives the movable block 221 to move downward, so that the bottom of the movable block 221 contacts the upper hook 32 and is stuck by the upper hook 32. When the agitator 1231 moves down to the bottom end position in the processing chamber 113 and is close to the sediment, under the action of the inclined surface of the protrusion, the baffle 21 overcomes the elastic force of the first spring and synchronously drives the scraper plate 31 to move away from the bracket 114 in the cavity, and the scraper plate 31 contacts the sediment and drives the sediment to move toward the discharge port. Fig.10As shown by the middle arrow c, further, a plurality of lower hook claws 33 for hooking the sediment are provided on the bottom of the scraper plate 31 and the contact surface with the sediment. By providing the lower hook claws 33, the sediment can be hooked by the shape of the hook claws and then driven to move the sediment, thereby avoiding the situation where the sediment cannot be driven to move due to insufficient friction, thereby ensuring the discharge and treatment of the sediment.

[0056] In summary, the activity state of the lifting and stirring member 123 can be divided into the following three stages:

[0057] Stage 1, such as Fig.11 As shown, when the agitator 1231 reciprocates up and down along the intracavitary support 114, the end of the contact wedge 22 continues to contact the surface of the intracavitary support 114. At this time, the top of the first plate opening 23 is connected to the bottom of the plate opening 1233, and the mud scraper plate 31 is connected to the bottom of the first plate opening 23. When the agitator 1231 moves, the liquid can flow through the mud scraper plate 31, the plate opening 1233, and the first plate opening 23.

[0058] Phase 2, such as Fig.12 As shown, when the agitator 1231 moves down to the bottom position in the processing chamber 113 close to the sediment, the end of the contact wedge 22 just contacts the protrusion of the intracavity bracket 114, and under the action of the inclined surface of the protrusion, the baffle 21 overcomes the first spring force and moves away from the intracavity bracket 114. At this time, the first plate opening 23 is no longer connected to the plate opening 1233, but the second plate opening 24 is connected to the bottom of the plate opening 1233, and the mud scraping plate 31 is connected to the bottom of the second plate opening 24. The bottom of the agitator 1231 and the bottom of the mud scraping plate 31 contact the sediment and squeeze the sediment, so that the oil-containing liquid in the sediment is squeezed out and reaches the position above the agitator 1231 in the processing chamber 113 through the mud scraping plate 31, the second plate opening 24, and the plate opening 1233, and can be fully mixed with the agent in the liquid for oil removal.

[0059] When the impeller 1231 moves upward, the end of the contact wedge 22 does not contact the protrusion, and under the action of the first spring, the baffle 21 is reset. At this time, the first plate opening 23 is connected to the bottom of the disk opening 1233, and the stage one is repeated. For the sediment, the sediment will be squeezed once in each up and down movement cycle of the impeller 1231, so that the oil-containing substances in the sediment are fully removed, thereby achieving effective oil removal of the oil-containing sludge waste liquid.

[0060] Stage three, such as Fig.13As shown, when the liquid in the processing chamber 113 is discharged, as the liquid level drops, the hollow floating plate 115 moves down to the surface of the stirring plate 1231 and squeezes the top ring 1234, so that the top ring 1234 overcomes the elastic force of the second spring and moves down, driving the first connecting frame 1235 and then driving the slider 1236 to move down, and the slider 1236 then drives the movable block 221 to move down, so that the bottom of the movable block 221 contacts the upper hook 32 and is stuck by the upper hook 32. When the stirring plate 1231 moves down to the bottom end position in the processing chamber 113 close to the sediment, under the action of the inclined surface of the protrusion, the baffle 21 overcomes the elastic force of the first spring and synchronously drives the scraper plate 31 to move away from the intracavity bracket 114. The scraper plate 31 then contacts the sediment and drives the sediment to move toward the discharge port, ensuring the discharge of the sediment.
