Automatic sand flushing device for upper electric field water discs

Abstract

The invention relates to an automatic sand flushing device for upper electric field water discs. The automatic sand flushing device for the upper electric field water discs comprises automatic sand removing plates, a back flushing inlet pipe, multiple back flushing water pipes, multiple spray nozzles and downpipes, the automatic sand removing plates are arranged on the upper sides of the bottom faces of the corresponding water discs, the water discs are each in a V shape, and correspondingly, a water groove is formed in the bottom of each water disc; the back flushing water pipes are arranged above the automatic sand removing plates, the spray nozzles are evenly distributed on the back flushing water pipes, the back flushing inlet pipe is communicated with the back flushing water pipes to supply water to the back flushing water pipes, and the downpipes are communicated with the water grooves in the bottoms of the water discs. By means of the automatic sand flushing device for the upper electric field water discs, the defect that sediments and mechanical impurities cannot be removed automatically through original double-oil-taking and double-electric-field electric desalting and dewatering equipment in the crude oil desalting and dewatering process of upper electric fields is overcome.

Description

technical field [0001] The invention relates to the field of electric desalination tanks, in particular to an automatic sand flushing device for an upper electric field water tray. Background technique [0002] Double oil inlet double electric field electric desalination and dehydration technology In the space above the center line of the electric desalination tank 1, several square or rectangular semi-closed water pans 2 are arranged, and each water pan 2 is equipped with an upper electric field unit 3 ( see figure 1 ). Since the crude oil contains more sediment and mechanical impurities, it will settle to the bottom of each water pan 2 during the desalination and dehydration process of crude oil. Although the bottom of the water pan 2 has been designed as a sloping plate, some sediment and mechanical impurities It can be taken away with the discharge of salty sewage, but there is still a part of stubborn silt and mechanical impurities deposited on the sloping plate at th...

AI Technical Summary

Problems solved by technology

Due to the fact that the current equipment in the petrochemical industry is inspected after three years of operation, after three years of operation, the stubborn sediment and mechanical impurities accumulated on the sloping plate at the bottom of the water pan 2 gradually form a higher accumulation layer, occupying the bottom of the water pan 2 The limited space affects the normal operation of the upper electric field
