During the use of tank trucks, in order to ensure product quality, it is necessary to regularly inspect and maintain the internal facilities of the tank trucks, and provide conditions for re-testing the tanks and re-compiling the volume meter. Cut tanks will have residues inside during long-term operation, which will inevitably cause product contamination during replacement. Therefore, cleaning of tank trucks is very important during their operation.
It is not very difficult to clean light oils and oil tanks with less sedimentary residue (commonly known as sediment), or small-volume oil tanks. However, for crude oil storage tanks with more sediments and larger volumes, waxy crude oil and its mixture of hydrocarbons and non-hydrocarbon compounds have a more complex composition. It contains both liquid hydrocarbons at room temperature and solid paraffin, microcrystalline wax, and colloidal asphaltene at room temperature. Cleaning is very difficult, so how to quickly and effectively clean the inside of the tanker?
At present, steam cleaning, chemical cleaning and high-pressure water cleaning are commonly used for oil tank cleaning. On the one hand, high-temperature steam cleaning is mostly open steaming tanks. After steaming, manual cleaning is required, which will cause certain safety hazards to the surrounding environment and labor, and the cleaning quality is seriously affected by labor. On the other hand, chemical agents and petrochemical products transported by tank trucks are very easy to react, which increases the risk factor. The wastewater after cleaning needs special treatment, otherwise it will cause environmental pollution. At present, this cleaning method is gradually being eliminated. Therefore, the mainstream cleaning method with high water jet cleaning technology has gradually become the darling of the industry.
The common ways of being affected by substances are high pressure and low pressure. You can choose according to the different objects to be cleaned. High-pressure water jets are used to strike, erode, cut and remove the inner wall of the tank. Water as the cleaning medium has the advantages of high efficiency, environmental protection, non-corrosiveness and pollution-free. High-pressure water jet cleaning technology has the advantages of easy mechanization and automation. In order to reduce the impact of manual cleaning, automated high-pressure water cleaning technology is widely used in tank truck cleaning, and is combined with environmentally friendly configurations such as sewage treatment systems to recycle and treat wastewater in the cleaning process, thereby achieving green and safe tank truck cleaning.
Guangyuan Cleaning Equipment's tanker high-pressure water automatic cleaning system is mainly composed of a high-pressure water cleaning system, a sewage treatment system, a drying system, and a hoisting positioning system. It can replace manual work to complete the extraction, cleaning, and drying of tanker cleaning, and recycle the wastewater after cleaning. The entire cleaning process only requires manual assistance, reducing manual intervention, reducing labor intensity, and effectively improving the efficiency, quality, and safety of tanker internal cleaning.
The railway tanker automatic cleaning system is controlled by a remote control, and can stop, enter the tank, pump out or clean any tanker at any position. The lifting and opening and closing mechanism completes the tank cleaning at a close distance, which can effectively ensure the intensity of the strike, and most of the rust is cleaned by pressure water. The inner wall of the oil tank is cleaned point by point using high-pressure water jet three-dimensional cleaning technology. The cleaning of each position in the oil tank is controllable, and each position can be cleaned repeatedly separately; the pumping motion actuator can collect, summarize, and suck away the cleaning sewage and a large amount of rust cleaned up in time, and basically no one needs to go down the tank; after cleaning, the inside of the tanker can be quickly dried. If the user needs it, a robot can be selected to enter the tank for inspection.
This set of high-pressure water automated tanker cleaning system can automatically control the entire cleaning process through the control system. It can clean the inner wall of the oil tank point by point and can repeat the cleaning of each position individually. The system can perform a general cleaning of a tanker for 40 minutes and a special cleaning of a tanker for 70 minutes. After cleaning, the interior of the trailer is dry and clean and will not rust for 10 days, which provides convenience for daily cleaning, maintenance and cleaning of tankers.
