Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of repair devices, in particular to a repair device and method for treating surface water oil hydrocarbon pollution. BACKGROUND

[0002] In the treatment of surface water oil hydrocarbon pollution, after the initial treatment such as skimming oil and oil containment boom, there will still be a small amount of floating oil in the water. This kind of pollutant is difficult to completely remove by gravity separation, and the adsorption method can repair it by virtue of the "molecular level capture" ability.

[0003] There are many existing technologies for surface water oil hydrocarbon pollution repair devices, for example:

[0004] Chinese patent publication No. CN222099698U discloses a repair device for river surface water oil hydrocarbon pollution, which comprises a case, a water inlet pipe and a water outlet pipe are installed on the left side and the front end of the case respectively, a connecting frame is arranged on the left side of the case, a water suction pipe is communicated below the connecting frame, a bottom pipe one and a bottom pipe two are arranged on the front and rear ends below the connecting frame respectively, a lifting assembly is arranged between the bottom pipe one and the bottom pipe two and the connecting frame, a plurality of evenly distributed spray heads one are communicated above the bottom pipe one, a plurality of evenly distributed spray heads two are communicated above the bottom pipe two, a vacuum pump and an air pump are installed on the top of the case, an installation box is installed on the top of the case, the installation box is communicated with the vacuum pump, and a stirring assembly is arranged inside the installation box; the invention can suck and purify the water containing a large amount of oil hydrocarbon pollutants on the river surface water, and can effectively improve the purification and repair efficiency by purifying the lower layer of river surface water.

[0005] However, there are still some problems to be solved in actual use:

[0006] 1. Oil hydrocarbons, due to their density significantly lower than that of surface water (usually between 0.7-0.9g / cm³), will continue to float on the surface of the water body to form irregular oil films, and will be affected by water flow disturbance and wind force, and the oil film will easily spread. This dynamic and dispersed state makes it difficult to fully adsorb the oil film during collection.

[0007] 2. The mainstream method is to fix the middle part of the activated carbon at the center position of the water surface contact (such as by floating frame fixation, rope suspension and other methods), so that the whole activated carbon maintains a relatively static contact state with the water surface. This fixing mode has obvious defects: since oil hydrocarbons are mainly concentrated on the surface of the water body, and the middle part of the activated carbon directly contacts the core area of the oil film, a large amount of oil hydrocarbons will be quickly adsorbed in this part, and the adsorption saturation state will be reached in a short time; the edge and lower layer of the activated carbon do not contact the oil film sufficiently, and the adsorption capacity is not effectively utilized, forming an uneven phenomenon of "middle saturation and edge idling", which affects the service life of the modified activated carbon.

[0008] Therefore, a device and method for treating surface water oil hydrocarbon pollution remediation are provided. SUMMARY

[0015] As a further improvement of the technical solution, the modified activated carbon is provided with a base outside, the modified activated carbon is clamped at the bottom of the base, and a spacing groove is arranged on the surface of the base, the spacing grooves are arranged in an array on the surface of the base.

[0016] As a further improvement of the technical solution, the fixing assembly comprises a limiting seat arranged on one side of the base plate, hollow columns are arranged on both sides of the limiting seat, a long rod is slidably arranged on the inner wall of the hollow column, a compression spring is arranged between the hollow column and the long rod, and a clamping plate is arranged at the end of the long rod.

[0017] As a further improvement of the technical solution, the clamping plate is in the shape of a circular arc, and the clamping plate is attached to the surface of the base plate when clamping the bottom of the base plate.

[0018] As a further improvement of the technical solution, the end of the extension plate is provided with a scraper, the scraper is in the shape of a circular ring with a larger opening at the bottom than at the top, the opening size at the top of the scraper is matched with the diameter of the base plate, and the surface of the base plate is scraped when the base plate moves in the vertical direction.

[0019] The second object of the present application is to provide a processing method for the remediation device for treating surface water oil hydrocarbon pollution.

[0020] S1, control the impeller floating seat to drive the base to move to the designated repair area, and automatically gather the oil hydrocarbon floating on the water surface around the base through the gathering assembly, and pass through the modified activated carbon during the oil hydrocarbon gathering process, so as to accelerate the adsorption of the oil hydrocarbon on the surface of the surface water.

[0025] This device for treating petroleum hydrocarbon pollution in surface water involves a main gear that drives a double-headed gear set to mesh and rotate. The double-headed gear set, in turn, drives a driven gear rod to mesh and rotate. The driven gear rod, in turn, drives an eccentric wheel to rotate coaxially. As the eccentric wheel rotates, it presses against the surface of a substrate. A sliding rod at the bottom of the substrate slides inside a cylindrical column and compresses an elastic element. When the eccentric end of the eccentric wheel rotates to the surface of the substrate, the substrate height is compressed to its lowest point. The substrate then causes the modified activated carbon to reciprocate on the surface of the surface water, increasing the contact area between the modified activated carbon and petroleum hydrocarbons, thereby extending the service life of the modified activated carbon.

[0026] This device, used for the remediation of petroleum hydrocarbon pollution in surface water, allows operators to move to the vicinity of the base and slide the long rod at the end of the clamping plate against the inner wall of the hollow column. During the sliding process, the long rod compresses the compression spring, causing it to be in a compressed state. At this time, the clamping plates are separated, and the clamping force on the outer wall of the base disappears, making it easier to remove the base and replace the modified activated carbon inside, thus improving the replacement efficiency.

The scraper (104) is an annular shape with a bottom opening larger than the top opening. The top opening size of the scraper (104) is adapted to the diameter of the base (201). When the base (201) moves in the vertical direction, the scraper (104) scrapes its surface.

7. A method of using a surface water petroleum hydrocarbon pollution remediation device, implemented by the surface water petroleum hydrocarbon pollution remediation device according to any one of claims 1-6, characterized in that: Includes the following steps: S1. Control the impeller float (101) to move the base (100) to the designated repair area. The petroleum hydrocarbons floating on the water surface around the base (100) are automatically gathered to it through the agglomeration component (300). During the agglomeration of petroleum hydrocarbons, modified activated carbon (200) is passed through the modified activated carbon, thereby accelerating the adsorption of petroleum hydrocarbons on the surface of the surface water. S2. During the process of agglomerating component (300) agglomerating petroleum hydrocarbons on the water surface, the agglomerating component (300) drives the adjusting component (400) to reciprocate in the vertical direction. The surface of the adjusting component (400) is provided with modified activated carbon (200), which increases the contact area between the surface of the modified activated carbon (200) and the petroleum hydrocarbons. S3. The base (201) is fixed by the fixing component (500). When the modified activated carbon (200) inside the base (201) is saturated with adsorption, it is replaced.
