Description

Technical Field

[0001] This utility model relates to the technical field of oil pollution treatment equipment, and in particular to a device for controlling the spread of oil pollution and harmlessly disposing of residual oil. Background Technology

[0002] During oil extraction activities, it is inevitable that some residual oil will flow into the water bodies and other environments where the oil extraction equipment is located. Common oil spills, residual oil, and oil pollution include three forms: solid, liquid, and gas. Therefore, it is necessary to take certain measures to prevent the spread of this residual oil and to treat it harmlessly. In existing technologies, some treatment methods involve using a powder spraying gun to draw in dry powder and spray it into the water body to be treated. The dry powder then adsorbs the residual oil, preventing its spread, and solidifies the residual oil for harmless treatment and recycling.

[0003] However, when using existing powder spray guns, the dry powder used to treat oil stains needs to undergo a hydration reaction in the presence of water in order to quickly adsorb the oil stains. However, on soil or water surfaces contaminated with oil, moisture is often blocked by the oil stains. Therefore, it is necessary to design a device to add water vapor before or after blowing the dry powder onto the oil stains. Utility Model Content

[0022] To facilitate understanding of this utility model, it will be described more comprehensively and in detail below with reference to the accompanying drawings and preferred embodiments. However, the scope of protection of this utility model is not limited to the following specific embodiments.

[0023] It should be noted that when a component is described as being "fixed to, attached to, connected to or connected to" another component, it can be directly fixed to, attached to, connected to or connected to the other component, or it can be indirectly fixed to, attached to, connected to or connected to the other component through other intermediate connectors.

[0024] Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by those skilled in the art. The technical terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the scope of protection of this invention. Example

[0025] A device for controlling the spread of oil pollution and rendering residual oil harmless includes a blower 1 and a humidification assembly 2 or a powder spraying assembly; the humidification assembly 2 includes a water bottle 21, a water outlet pipe 22, and a nozzle 23; the air inlet of the nozzle 23 is connected to the nozzle 11 of the blower 1 or the air outlet of the extension pipe 4 via a connecting assembly 3. Figure 2 and Figure 3 As shown, the nozzle 23 has a threaded opening in the middle for connecting to the water bottle 21. One end of the water outlet pipe 22 is located inside the water bottle 21, and the other end is located at the air outlet end of the nozzle 23. The water outlet pipe 22 is connected to the inner wall of the air outlet end of the nozzle 23 via a bracket 24. Figure 1As shown, the air inlet end of the nozzle 23 is connected to the nozzle 11 of the blower 1 via the connecting assembly 3; Figure 5 As shown, the air inlet of nozzle 23 is connected to the air outlet of extension pipe 4 via connecting component 3.

[0026] In this embodiment, the water bottle 21 is a common mineral water bottle 21, and the threaded opening in the middle of the nozzle 23 for connecting the water bottle 21 matches the threaded opening of the mineral water bottle 21, which facilitates use on the construction site.

[0027] In this embodiment, the inner diameter of the air inlet end of the nozzle 23 is larger than the inner diameter of the air outlet end; this can maintain a certain pressure inside the nozzle 23. Since the water bottle 21 is connected to the nozzle 23, the water in the water bottle 21 can flow out through the water outlet pipe 22 under pressure; thereby reaching the air outlet end of the nozzle 23, and being dispersed into water vapor under the action of wind.

[0028] In this embodiment, the device for controlling oil pollution and rendering residual oil harmless is used when the airflow blowing towards the oil or dry powder to be treated carries moisture. This allows the dry powder to hydrate with the moisture, thus rapidly adsorbing the oil. When the dry powder comes into contact with water, the silicon-oxygen bonds and metal-oxygen bonds on its surface combine with water molecules, undergoing a hydration reaction. Millions of these reactions form chemical bonds and new charges on the solid surface.

[0029] Taking common magnesium silicate as an example: MgSiO3 + H2O → Mg 2+ + H2SiO4 2- When magnesium silicate is added to water, it produces silicate anions and simultaneously forms Mg. 2+ Ions. When the oil-water boundary is within the special pore size environment of the adsorbent, and under the catalytic effect of rare earth elements, free H+ ions will form. + And oil-water combined negative ions, ROH - R represents various hydrocarbons in petroleum. Multiple ions form a relatively stable bonded state in a special pore size environment, which is called chemisorption.

[0030] This invention relates to a dry powder micro-water control (removal) oil method, which requires only a small amount of water to be effective. The atomization of this invention is based on Bernoulli's principle. Compared with other principles such as pressure, centrifugation, and ultrasound, it can produce extremely fine water mist. Ultrasonic mist is clearly visible, while pressure and centrifugation mists, when applied to dry powder or oil contaminants, show clearly visible water droplets rolling, requiring a large amount of water and having low portability and efficiency.

[0031] In this embodiment, as Figure 4As shown, the connecting assembly 3 includes a first connecting pipe 32 and an elastic sealing ring 31; the front section of the elastic sealing ring 31 is folded back to form a double-layer part 311 and a single-layer part 312; the connecting end of the first connecting pipe 32 is connected to the nozzle 11 or the air outlet end of the extension pipe 4, the air outlet end of the nozzle 11 or the extension pipe 4 is disposed in the through hole of the first connecting pipe 32, and the air outlet end of the nozzle 11 or the extension pipe 4 together with the first connecting pipe 32 to compress the double-layer part 311; the single-layer part 312 is attached to the inner wall of the connecting end of the first connecting pipe.

[0032] In this embodiment, a second connecting pipe 33 is provided on the first connecting pipe 32, and the inner diameter of the second connecting pipe 33 is larger than the inner diameter of the first connecting pipe 32; the second connecting pipe 33 is connected to the air outlet end of the nozzle.

[0033] In this embodiment, a through hole is provided on the first connecting pipe 32 at the position corresponding to the single-layer part 312. A top pin 35 and an elastic gasket 36 are provided in the through hole. The elastic gasket 36 is located between the top pin 35 and the single-layer part 312. The top end of the top pin 35 extends out of the through hole. A first hose clamp 34 is provided on the first connecting pipe 32 at the position of the top pin 35. The first hose clamp 34 presses against the top pin 35, thereby completing the fixed connection between the first connecting pipe 32, the single-layer part 312 and the air outlet end of the nozzle 11 or the extension pipe 4.

[0034] In this embodiment, the connection structure between the extended tube 4 and the nozzle 11 can adopt the connection structure of patent CN220295023U; or it can adopt a conventional pipe snap-fit ​​structure.

[0035] In this embodiment, as Figure 6 and Figure 7 As shown, the powder spraying assembly includes a mesh bucket 5, which comprises a mesh bucket body 51, a connecting rod 52, and a threaded connecting collar 53. The mesh bucket body 51 is fixedly connected to the connecting rod 52, and the connecting rod 52 is fixedly connected to the threaded connecting collar 53 via a second hose clamp 54. Two second hose clamps 54 can be provided. The threaded connecting collar 53 is threadedly connected to the air outlet end of the extension pipe 4. In this embodiment, the thread on the threaded connecting collar is an external thread, and the air outlet end of the extension pipe 4 is provided with an internal thread. In this embodiment, the dry powder for treating oil stains is placed inside the mesh bucket body 51; the air outlet end of the extension pipe 4 faces the mesh bucket body 51, thereby blowing the dry powder inside the mesh bucket body 51 towards the location of the oil stains.

[0036] In this embodiment, the humidification component 2 and the powder spraying component are not used simultaneously. That is, powder spraying is not performed while humidification is in use to prevent the dry powder from being unable to disperse after being humidified. During use, the dry powder for treating oil stains can first be sprayed onto the oil stain using the powder spraying component. When there is no water at the oil stain location, the humidification component 2, under the action of wind, disperses the water into water vapor, which is then blown onto the dry powder surface of the oil stain. The dry powder for treating oil stains undergoes a hydration reaction in the presence of water, thereby achieving rapid adsorption of the oil stain.
