Abstract

The invention discloses a large crude oil storage tank sludge cleaning device, and provides an economical and efficient cleaning device for preventing deposition of crude oil sludge of large crude oil storage tanks. The large crude oil storage tank sludge cleaning device comprises a device body; the device body is arranged at the bottom of a crude oil storage tank; a rail is arranged in the crude oil storage tank; the device body can move on the rail; the device body is of a semi-closed structure with opened bottom surface and front surface; multiple nozzles and oil outlets are formed in one side surface of the device body; the nozzles are arranged below the side surface for spraying oil into the device body; and the oil outlets are formed above the side surface.

Description

technical field [0001] The invention relates to the field of sludge cleaning of crude oil storage tanks, in particular to a large crude oil storage tank sludge cleaning device. Background technique [0002] With the rapid development of China's economy, the demand for oil is increasing day by day. For China, strategic oil reserves play a very important role in ensuring national security and sustainable development of the national economy. [0003] When extracting crude oil from crude oil wells, in the natural environment of crude oil wells, it is inevitable that some ore mud will seep into and be produced together with crude oil. When crude oil is stored in crude oil storage tanks, the condensable substances in it settle at the bottom of the tank to form high-viscosity sludge. If the sludge accumulates, it will cause the loss of crude oil, the reduction of the storage capacity of the oil tank, and the water and salt in the sludge will continue to corrode the bottom of the ...
