How to drain oil from gas station oil tank

After using the double-layer oil tank in the gas station for a period of time, it needs to be cleaned. Regarding the cleaning problem, especially how to remove the bottom oil of the pressure vessel, as a professional pressure vessel manufacturer, let the editor take everyone to understand. How to remove the bottom oil when cleaning the oil tank of the gas station.

The specific method of using pad water to drain the bottom oil of the oil tank:
1. After the double-layer oil tank is emptied, the oil stored at the bottom must be accurately measured and recorded to determine the height of the pad water and the running time of the pump.

2. When padding water, select the appropriate opening and use a hose with electrostatic lead-out line to extend to the bottom of the oil tank. After the padding is completed, pull out the water inlet hose from the oil tank, and use the oil pipeline or temporarily laid hose to connect Put up the bottom oil into the empty tank or the oil-water separation tank.

After confirming that the bottom oil of the oil tank has been drained for 30 minutes, test and record the concentration of oil and gas in the pressure vessel through the oil measuring hole of the double-layer oil tank. The specific method of using mechanical suction to discharge the bottom oil:
1. Pass the oil tank drain valve to drain the oil by itself, then remove the oil inlet pipeline valve, cut off the passage with other oil pipelines or oil tanks, and seal the pipeline flanges separated from the oil tank with blind plates.

2. Insert the rubber hose from the other end of the oil inlet pipeline into the bottom of the double-layer oil tank, pump the bottom oil with a hand pump or vacuum pump, and then put it into the empty tank, oil-water separation tank or oil drum, etc. Thirty minutes after these are completed, the oil and gas concentration in the tank should be tested and recorded through the oil metering hole, oil drain hole, etc.

3. After the bottom oil is drained, it is recommended to use a hand pump or vacuum pump to pump the water stored in the bottom of the oil tank to the sewage tank, etc., and it is prohibited to directly drain it into the sewer.
