With the rapid development of China's national economy, the demand for oil has increased extremely; With the development of the railway transportation industry, especially after the gradual acceleration of the railway, the volume of petroleum products transported by rail is increasing. At present, most of the railway tank cars are manually cleaned, and there are the following problems in manual cleaning
i) Manual cleaning is labor-intensive, which increases the cost of car washing.
2) Poor operating environment and high danger are not conducive to normal safety production.
3) The residual oil stain cannot be completely removed, and the car washing time is long, and the quality is difficult to guarantee.
4) It is easy to suffer from a variety of occupational diseases, and it is easy to cause operators to suffer from a variety of occupational diseases, such as diseases, arthritis and respiratory diseases, which cause great harm to the physical and mental health of operators.
In order to improve the safety and environmental protection of railway tank car cleaning, the industry's automatic cleaning system based on high-pressure water jet cleaning technology to clean tankers has gradually attracted attention, which is mainly composed of high-pressure water cleaning mechanism, waste liquid residue pumping mechanism, wastewater treatment mechanism, etc., which can replace manual completion of a series of cleaning operations such as tanker residue pumping, cleaning, and drying, so as to realize the efficient and low-pollution cleaning of the inner wall of railway tankers.
The railway tank car automatic cleaning system is mainly composed of high-pressure water cleaning system, sewage treatment system, drying system and hoisting positioning system, etc., which can realize automatic cleaning and drying of railway tank cars, which can be washed in a closed environment throughout the process, and the waste solid after cleaning is treated, which fundamentally improves the working conditions of workers, protects the health of workers, improves the efficiency and quality of car washing, and greatly reduces the pollution to the environment.
Before cleaning: automatic residue pumping device replaces manual completion of automatic residue pumping operation inside the tanker, without manual tank operation, reducing potential safety hazards and improving operation efficiency;
Cleaning: the use of high-pressure water jet technology equipped with three-dimensional rotating nozzle, the nozzle continues to rotate, so as to constantly change the striking point with its strong impact force to clean the tanker, the nozzle jet to the tank wall at the same time tangential and radial angle, the formation of a water wedge, strengthen the peeling effect at the same time, the inside of the tanker 360 ° without dead angle cleaning.
After cleaning: The drying system can automatically dry the inside of the tanker, so that the inside of the tanker is dry and clean, and the cleaned waste solid is treated, and the entire cleaning process is carried out in a closed environment, which can effectively improve the cleaning efficiency and quality of the tanker and reduce the pollution to the environment.
Railway tank car automatic cleaning system, automatic cleaning equipment PLC control, cleaning process can be eradicated from the actual situation to flexibly adjust cleaning time, pressure and other parameters, and can be stopped at any position, into the tank, pumping or cleaning any tank car, the system operation is simple and the degree of automation is high, the whole process does not need to be manually into the tank, you can complete the cleaning, 40min for a tanker, 70min for a tanker, all the loose rust in the tank can be cleaned off, and the rust of the tight layer can also be cleaned up 96% Above, the cleaned tank will not return to rust for at least 5 to 10 days, which is a set of high-efficiency and low-pollution automatic cleaning solutions for railway tank cars.
