Mechanical cleaning technology of oil tank will be cleaning the bottom of the tank is transferred to the mobility of the oil receiving tank, cleaning oil supply tank in oil by heating and pressurizing by cleaning machine stirring and dissolving tank residual oil after solidification, filter to remove impurities after transferred to the receiving tank, at the end of each part of the storage tank for cleaning cycle with warm water, in order to achieve the conditions of hot pot. Continuous injection of inert gas to the tank to be cleaned in the cleaning process, so that the internal oxygen concentration remained below 8VoL%, to prevent the occurrence of explosion danger; equipped with oxygen and combustible gas detection device, time monitoring of cleaning oxygen and combustible gas in the tank concentration, to ensure safe operation of mechanical cleaning.
Cleaning process 1 equipment installation
Use light pipeline and valve to quickly complete the installation of the equipment and connection of the pipeline, and test the overall tightness of the system.
2 oil transfer
The flow of oil in the oil tank is transferred to the receiving oil tank through the transfer module.
3 the same kind of oil cleaning
The cleaning module will clean the oil supply tank in oil by heating and pressurizing, the cleaning machine is arranged in the tank wall of the tank or a single disk access hole on the break, the tank cleaning oil solidification dissolved, which has good fluidity, and through the transfer of the filtered transferred to the receiving module oil tank;
4 warm water cleaning
To add to the advance of oil-water separation module in water for heating and pressurizing by cleaning module, through various parts of machine cleaning tank, the oil-water oil-water separation module separation warm water cleaning cycle in the mixture, the separated oil transferred from the pump to the receiving tank recovery, separated water to warm water cleaning cycle homework.
Comparison of technical advantages
The storage tank operating personnel manual cleaning from the tank wall cleaning ladder manhole Jinren tank, tank space, air circulation, combustible gas concentration is high, prone to poisoning and explosion accidents, the construction work environment is bad, serious harm to the health of workers; on the other hand, a large number of sewage removal from the tank of oil pollution caused by the environment and cleaning the tank and the surrounding area pollution, at the same time cleaning cycle (mean two months) reduced the reservoir storage adjustment ability, directly affect the normal production of the reservoir area, a large number of waste oil tank bottom also caused the waste of resources and environmental pollution. Compared with traditional tank cleaning methods, mechanical cleaning technology achieves closed storage tank cleaning process, which has the characteristics of short cleaning time, health, safety, high recovery rate of tank bottom oil, remarkable social and economic benefits.
