Abstract

The invention provides an integrated main skid device of a mechanical cleaning system for a large-scale oil storage tank, and relates to the technical field of mechanical cleaning devices. The main skid device comprises negative pressure filters, vacuum tanks, centrifugal pumps, a vacuum pump, a gas-liquid separation tank, a positive pressure filter, an oil skimmer and a cleaning strainer. Each negative pressure filter is connected with one end of the corresponding vacuum tank, and the other end of each vacuum tank is connected with the corresponding centrifugal pump. The other end of each centrifugal pump is connected with the oil skimmer, the positive pressure filter and an external flange. Each vacuum tank is connected with the input end of the vacuum pump. The output end of the vacuum pump is connected with the gas-liquid separation tank. The oil skimmer and the cleaning strainer are connected with the bottoms of the vacuum tanks respectively. By means of the main skid device, operation and management are simple, convenient and easy to implement, and integration of management and control is achieved; meanwhile, the on-line gas monitoring function is added, safety monitoring in the mechanical cleaning process can be more facilitated, and the cleaning process can be better optimized. The novel process and device have an automatic deslagging function, solid-liquid separation can be realized, and therefore the oil tank can be better cleaned.

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] Existing oil storage tank mechanical cleaning equipment, when pumping high-viscosity liquid, the main centrifugal pump is prone to cavitation, and the suction capacity is weak; there is no automatic slag discharge function; the boost scheme has high power consumption, low lift and small flow; oil skimming It adopts gravity separation, open operation, a large amount of oil and gas volatilize, and the safety and environmental protection are poor; the gas online detection is a separate system; and it only detects oxygen and combustible gas LEL%. [0003] Therefore, a technical problem that needs to be solved urgently is how to creatively propose an effective measure to meet the needs of practical applications. Summary of the invention [0004] In view of the deficiencies...
