Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection, and specifically relates to a device for dehydrating and de-solidifying oily sludge. Background Art

[0002] Generally, the oily sewage and oily sludge in refineries come from various processes of crude oil processing, including the initial water cutting of crude oil storage tanks, water cutting of crude oil electro-de-salting, condensed separation water and washing water of oil gas and oil products, etc., and also the washing water of refining equipment and oily sewage cleaned from the bottom of tanks generated during maintenance. After the oily sewage is pretreated by oil separation, coalescence forms oily sludge. The composition of the oily sludge is extremely complex, containing not only a large amount of aged crude oil, wax, asphaltene, colloid, etc., but also various chemical agents such as demulsifiers and corrosion inhibitors added during the production process.

[0003] After retrieval, a document with the publication number (CN210367413U) discloses a device for dehydrating and de-solidifying oily sludge, which includes an oily sludge collection and heating unit, a full-automatic dosing and mixing reaction unit, and an oily sludge heat preservation and dehydration unit. The oily sludge collection and heating unit includes an oily sludge heater, a filter, an oily sludge pump, and a flow meter connected in sequence.

[0004] By processing the oily sludge with a relatively high water content through the above three units, namely the oily sludge collection and heating unit, the full-automatic dosing and mixing reaction unit, and the oily sludge heat preservation and dehydration unit in the above device, the separation of oil, water, and sludge in the oily sludge can be achieved, and the effects of dehydration and purification treatment can be achieved.

[0005] The above device separates oil, water, and sludge from oily sludge through multiple units, and needs to separately separate oil, water, and sludge from oily sludge through multiple steps. The separation steps are too many. At the same time, after the oil sludge separation device separates, there will be a large amount of oil sludge in the device, and if it exists for a long time, it will cause the oil sludge to solidify and occupy the space in the device.

[0006] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0013] As a preferred embodiment of the present invention, the first stirring rod is a drooping sheet-like structure with a flat upper part and a convex lower part, and the lower side of the first stirring rod is an arc-shaped fan.

[0016] The present invention has the following beneficial effects compared with the prior art:

[0017] 1. For this oily sludge dewatering and de-solidifying treatment equipment, after the device is used up, the first motor drives the movable block to rotate through the output shaft. The movable block drives the diversion block to rotate and rub the inner wall of the first treatment tank, and the excess oil flows to the bottom of the first treatment tank through the diversion block and the guiding grooves on the diversion block, and is discharged through the pipeline at this time, avoiding the qualitative change of the oil accumulated in the first treatment tank for a long time and polluting the oil separated from the oil and water subsequently.

[0018] 2. For this oily sludge dewatering and de-solidifying treatment equipment, the oil, water and mud are separated through the cooperation between the first treatment tank and the second treatment tank, reducing the operation steps of this device.

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0030] Please refer to Figures 1-5, a waste oil sludge dehydration and desolidification treatment equipment, including a first treatment box 1, a columnar cavity is opened in the first treatment box 1; a second treatment box 2, a columnar cavity is opened in the second treatment box 2, the second treatment box 2 is connected to the first treatment box 1 through a pipeline, and the bottom end of the second treatment box 2 is fixedly connected to a sewage pipe 22; a feeding pipe 21, the feeding pipe 21 is arranged at the upper end of the second treatment box 2, and the feeding pipe 21 is fixedly connected to the second treatment box 2; a feeding pipe 11, the feeding pipe 11 is arranged at the upper end of the first treatment box 1, and the feeding pipe 11 is fixedly connected to the first treatment box 1; a centrifugal assembly, the centrifugal assembly is respectively arranged in the first treatment box 1 and the second treatment box 2; a cleaning assembly, the cleaning assembly is arranged in the first treatment box 1 and the cleaning assembly is used to clean the inner wall of the first treatment box 1, and the cleaning assembly includes a servo motor and a guide block 5, the servo motor is fixedly connected to the top of the first treatment box 1, and the guide block 5 is connected to the servo motor The guide block 5 is connected by transmission and rubs against the inner wall of the first treatment box 1 to scrape and clean. The cleaning component also includes a movable block 51, which is rotatably connected to the inner wall of the cavity of the first treatment box 1. One end of the guide block 5 is fixedly connected to the movable block 51, and the movable block 51 is fixedly connected to the output shaft of the servo motor. The movable block 51 is provided with a plurality of fan-shaped grooves. The other end of the guide block 5 is fixedly connected with a circular ring, which is rotatably connected to the inner wall of the first treatment box 1. The guide block 5 is a symmetrical spiral blade, and a plurality of guide grooves are provided on the blades of the guide block 5. A heating device is installed in both the first treatment box 1 and the second treatment box 2. The dirty oil sludge is fed into the first treatment box 1 through the feed pipe 11. At this time, the heating device continuously cools the first treatment box 1 and keeps the temperature of the dirty oil sludge at a suitable temperature, so that the dirty oil sludge is further effectively separated. Normally, as the temperature rises, the evaporation rate of water in the liquid will increase. In the dehydration of waste oil, high temperature helps to accelerate the evaporation of water in the oil, thereby achieving the purpose of dehydration. However, too high temperature may cause oil decomposition and reduce the desolidification effect, so the heating device always maintains a suitable temperature. When the device is used up, the first motor 4 drives the movable block 51 to rotate through the output shaft, and the movable block 51 drives the guide block 5 to rotate and rub the inner wall of the first processing box 1, and the excess oil flows to the bottom of the first processing box 1 through the guide block 5 and the guide groove on the guide block 5. At this time, it is discharged through the pipeline to avoid the oil from accumulating in the first processing box 1 for a long time and causing quality change, which will cause pollution to the oil separated from the subsequent oil and water.

[0031] It is worth noting that the heating device can perform continuous low-temperature heating on the first processing box 1. The heating device includes an air flow channel, a heating module for accommodating the material to be heated, a switch module, and an external interface for connecting external equipment. The water level controller body has been disclosed in an external low-temperature heating device (CN211353920U) in the prior art and will not be repeated here.

[0032] Among them, the centrifugal component includes a first motor 4 and a first stirring rod 41. Each first motor 4 is fixedly connected to the bottom of the corresponding first treatment tank 1 and the second treatment tank 2. The first stirring rod 41 is fixedly connected to the output shaft of the first motor 4. The first stirring rod 41 is a drooping sheet-like structure that is flat on the top and convex on the bottom. The lower side of the first stirring rod 41 is an arc-shaped fan. The first motor 4 drives the first stirring rod 41 to rotate and drives the waste oil sludge to rotate to generate centrifugal force, which is a device for physically separating water as the continuous phase from oil and water and mud as the dispersed phase. The greater the density difference between the dispersed phase and the continuous phase, the easier it is to separate the two phases. Similar to the situation in the gravitational field, under the condition that the density difference between the two phases is constant, the larger the particle diameter of the dispersed phase, the greater the velocity difference of the reverse movement between the two phases when reaching the equilibrium state in the gravitational field, so as to achieve rapid separation.

[0033] Among them, a drain pipe 12 is provided between the first treatment tank 1 and the second treatment tank 2. The drain pipe 12 is fixedly connected to the first treatment tank 1 and the second treatment tank 2 respectively. One end of the first treatment tank 1 is connected with a sludge discharge pipe 3 and a connecting pipe 32 through a pipeline. One end of the sludge discharge pipe 3 and the oil discharge pipe 31 are connected with a connecting pipe 32 through a pipeline. Valves are provided on the feed pipe 11, the drain pipe 12, the sewage discharge pipe 22, the sludge discharge pipe 3 and the oil discharge pipe 31. Oil, water and mud are discharged respectively through the corresponding drain pipe 12, sewage discharge pipe 22, sludge discharge pipe 3, oil discharge pipe 31 and connecting pipe 32. The separated water is discharged through the drain pipe 12. At this time, the reaction reagent is sent into the second treatment tank 2 through the feeding pipe 21, and the water is treated by the centrifugal component. The treated water is discharged through the sewage discharge pipe 22, thereby reducing the operation steps of the device, quickly separating oil, water and mud, reducing the separation steps, and improving the work efficiency.

[0034] Working principle: The waste oil sludge is fed into the first treatment tank 1 through the feed pipe 11. At this time, the heating device continuously cools the first treatment tank 1 and keeps the temperature of the waste oil sludge at an appropriate temperature, further enabling the effective separation of the waste oil sludge, etc. Generally, as the temperature rises, the evaporation rate of water in the liquid will increase. In waste oil dehydration, high temperature helps to accelerate the evaporation of water in the oil, so as to achieve the purpose of dehydration. However, too high a temperature may cause the decomposition of the oil quality and reduce the solid removal effect. Therefore, the heating device always maintains an appropriate temperature. The first motor 4 drives the first stirring rod 41 to rotate and drives the waste oil sludge to rotate along with it to generate centrifugal force, which is a device for physically separating water as the continuous phase from oil and water and mud as the dispersed phase. The greater the density difference between the dispersed phase and the continuous phase, the easier it is to separate the two phases. Similar to the situation in the gravitational field, under the condition that the density difference between the two phases is certain, the larger the particle diameter of the dispersed phase, the greater the velocity difference between the reverse operations of the two phases when reaching the equilibrium state in the gravitational field, so as to achieve rapid separation. Then, the oil, water and mud are discharged respectively through the corresponding drain pipe 12, sewage discharge pipe 22, sludge discharge pipe 3, oil discharge pipe 31 and connecting pipe 32. The separated water is discharged through the drain pipe 12. At this time, the reaction reagent is fed into the second treatment tank 2 through the feeding pipe 21, and the water is treated by the centrifugal component. The treated water is discharged through the sewage discharge pipe 22. The separated water is treated and discharged to reduce the impact on the environment, thereby reducing the operation steps of this device, quickly separating the oil, water and mud, reducing the separation steps, and improving the working efficiency. When the device is used up, the first motor 4 drives the movable block 51 to rotate through the output shaft. The movable block 51 drives the guide block 5 to rotate and rub the inner wall of the first treatment tank 1, and the excess oil flows to the bottom of the first treatment tank 1 through the guide block 5 and the guiding groove on the guide block 5, and is then discharged through the pipeline at this time, avoiding the quality change of the oil caused by long-term accumulation in the first treatment tank 1 and polluting the oil separated from the oil and water subsequently.
