Integrated large oil storage tank mechanical cleaning system main skid device

Abstract

The invention provides a main skid device of an integrated mechanical cleaning system for a large oil storage tank, and relates to the technical field of cleaning mechanical devices. The invention includes a negative pressure filter, a vacuum tank, a centrifugal pump, a vacuum pump, a gas-liquid separation tank, a positive pressure filter, an oil skimmer and a filter. The negative pressure filter is connected to one end of the vacuum tank, the other end of the vacuum tank is connected to the centrifugal pump, the other end of the centrifugal pump is respectively connected to the oil skimmer, the positive pressure filter, and the external flange, and the vacuum tank is connected to the input end of the vacuum pump , the output end of the vacuum pump is connected to the gas-liquid separation tank, and the oil skimmer and the filter are respectively connected to the bottom of the vacuum tank. The invention realizes easy operation and management, integration of management and control, and at the same time increases the gas online monitoring function, which is more conducive to the safety monitoring and optimization of the cleaning process in the mechanical cleaning process; the new process and new equipment have the function of automatic slag discharge, It can complete the solid-liquid separation for better cleaning of the oil tank.

Description

technical field [0001] The invention relates to a cleaning mechanical device, in particular to a main skid device of an integrated large-scale oil storage tank mechanical cleaning system. Background technique [0002] The existing mechanical cleaning equipment for oil storage tanks, when pumping high-viscosity liquids, the main centrifugal pump is prone to cavitation and weak suction capacity; there is no automatic slag discharge function; the booster scheme has high power consumption, low head, and small flow rate; oil skimming It adopts gravity separation, open operation, a lot of oil and gas volatilization, poor safety and environmental protection; gas online detection is a separate system; and only detects oxygen and combustible gas LEL%. [0003] Therefore, a technical problem that needs to be solved urgently is: how to innovatively propose an effective measure to meet the needs of practical applications. Contents of the invention [0004] In view of the deficiencies...
