Description
Technical Field
The invention relates to an oil sludge cleaning device, in particular to an oil sludge cleaning device for an underground water sealed cave depot.
Background
With the rapid development of Chinese economy, the demand of petroleum is increasing. For China, the storage of petroleum strategic reserves plays an important role in ensuring the national safety and the sustainable development of national economy. The underground water-sealed cave depot has the advantages of safety, economy, high efficiency, large storage capacity and the like, so the underground water-sealed cave depot is greatly developed in recent decades and is widely applied to the national petroleum strategic reserve.
When crude oil is collected in a crude oil well, part of slime inevitably seeps into the natural environment of the crude oil well and is produced along with the crude oil. When crude oil is stored in the oil tank, the easily condensable substances in the crude oil precipitate at the bottom of the tank to form high-viscosity oil sludge. If the oil sludge is accumulated, the crude oil quantity loss, the oil tank reserve capacity reduction, the continuous corrosion of the water and the salt in the oil sludge on the tank bottom and other problems can be caused. One method for solving the problem of deposit of the oil tank slime is to carry out periodical desilting, and the other method is to install a stirrer in the tank. Since 80 to 90% of the sludge component is reusable oil and wax, and a large amount of the available crude oil component is removed as waste by means of periodic dredging, a stirrer is generally installed in the crude oil tank to prevent the above-mentioned problems. The ground oil tank is of a circular structure, a central rotary-spraying stirrer is mostly adopted, and the conventional equipment and analysis method are mature. However, the underground water-sealed cave depot is cuboid in shape and 300-600 m in length, and a stirring system of the ground oil tank is not suitable for the underground water-sealed cave depot.
Therefore, it is necessary to design a sludge cleaning device for underground water sealed cavern.
Disclosure of Invention
The invention provides an underground water-sealed cave depot oil sludge cleaning device for overcoming the defects in the prior art, which can solve the problem of the deposition of the oil sludge in the underground water-sealed cave depot and can avoid the removal of a large amount of available crude oil components as waste materials.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides an underground water seal cave storehouse fatlute cleaning device, is including setting up a plurality of row's shower nozzles in underground water seal cave storehouse bottom, and every row of shower nozzle has a plurality of rows, the nozzle orientation of shower nozzle is unanimous, the shower nozzle is connected with the transmission pump, the oil inlet setting of transmission pump is on the upper portion in underground water seal cave storehouse and is located the crude oil liquid level under. The size of the crude oil ejection amount is controlled by selecting and using nozzles with different calibers.
Before oil is delivered, a transmission pump absorbs upper oil from an upper oil inlet and then sprays the upper oil in a bottom spray head of a cavern of an underground water seal cavern to drive bottom oil and oil sludge to move to the tail end of the cavern, the bottom oil and the oil sludge move upwards after meeting the cavern wall at the tail end of the cavern and move to the front end of the cavern along the upper layer after meeting the liquid level upwards, and finally the oil and the oil sludge in the whole cavern form a cycle to stir the oil sludge. After the oil and the oil sludge are stirred for a period of time, the oil and the oil sludge are uniformly stirred, and then the transmission pump is connected to the oil pumping system to pump oil, so that the oil sludge is sent out along with the oil, and the deposition of the oil sludge is avoided.
As a preferred technical scheme of the invention, the width of the underground water seal cave is 15-25m, two rows of spray heads are arranged at the bottom of the cave, and the distance from each row of spray heads to the cave wall is 3-6 m.
As a preferred technical scheme of the invention, the length of the underground water-sealed cavern is 400-600m, 6 rows of spray heads are arranged at the bottom of the cavern, and the distance between every two rows of spray heads is 80-100 m.
As a preferable technical scheme of the invention, the spray head comprises a spray pipe and a circular truncated cone-shaped spray nozzle connected with the spray pipe.
As a preferable technical scheme of the invention, the diameter of the small end of the nozzle is 160mm, the diameter of the spray pipe is 300mm, and the length of the spray head is 600 mm.
Compared with the prior art, the invention has the following beneficial effects:
the invention uses the fluid injection method to blow the oil sludge sediment at the bottom of the underground water-sealed cave depot, because of the uneven pressure generated by the fluid injection, the oil product in the underground depot generates integral circulation, so that the oil sludge sediment is mixed with the oil product at the upper layer again, and then is conveyed out by the oil delivery pump together with the oil product, thereby eliminating or reducing the oil sludge sediment in the underground depot, and the high-speed jet flow emitted by the spray head can break the accumulated sludge in the cave depot to dissolve the sludge.
The invention can solve the problem of slime deposition of the underground water-sealed cave depot and can avoid removing a large amount of available crude oil components as waste materials.
