Abstract

The invention discloses a petrol station buried tank cleaning system. The petrol station buried tank cleaning system comprises a buried tank, a cleaning recycling device, a cleaning machine, an oil-water separation device, a sludge dewatering machine, a reaction tank, an air flotation machine, a filtering device, a cleanser adding device, an inert gas generator and a vacuum pump, wherein the lower portion of the buried tank is provided with a water discharging valve and an outlet which are connected in the cleaning recycling device through recycling pipelines. According to the petrol station buried tank cleaning system, cleaned oil products can be reused, waste of oil products is prevented, and the resource reutilization rate is greatly improved. Sewage is recycled, the whole cleaning system becomes a closed cycle system, consumption of cleaning water is reduced, cleaning efficiency is high, and the environment is protected.

Description

technical field [0001] The invention relates to the field of cleaning, in particular to a cleaning system for buried tanks in gas stations. Background technique [0002] In the prior art, manual cleaning is generally used when cleaning the underground tank machinery at the gas station. There are following defects in this cleaning method: [0003] Workers need to go down into the tank, which has certain safety hazards; it is not environmentally friendly, and the crude oil tank is heated during the cleaning process, causing a large amount of volatilization of light oil, causing air pollution, and the sewage output during the tank cleaning process is high; and the utilization of sewage Low, can not achieve recycling; in the process of tank cleaning, there are dead corners that cannot be cleaned manually, and the cleaning effect is poor; it takes a long time, the cleaning efficiency is low, and there may be a secondary tank cleaning process. In the cleaning of buried tanks, ma...
