Dangerous chemicals tankers, as the name suggests, are tankers used to transport dangerous chemicals. Dangerous chemicals are hazardous chemicals and are toxic, corrosive, explosive, combustible, and combustible, and have properties for the human body, facilities, and the environment. Hazardous toxic chemicals and other chemicals. If leakage, residual or overflow is extremely dangerous, so the cleaning of dangerous goods tankers is very important. According to Xiaobian, a lot of car owners have a headache for this, and today Xiaobian will introduce a fixed cleaning system for dangerous chemicals tankers.
The system uses high-temperature steam cleaning. The system has a high cleaning quality for hazardous chemicals tankers. The entire system is a closed system and no steam is emitted, reducing pollution emissions. At the same time, the personnel in the cleaning process do not need to touch the interior of the tank car, which increases the safety and effectiveness of the system operation. And the discharge of cleaning solution to a designated wastewater treatment plant reduces the environmental impact. The tanker after cleaning can change the transportation product or repair.
With this system cleaning, the sewage containing hazardous chemicals at the bottom of the buffer tank does not need to be directly centrifuged to the sewage treatment plant. The waste gas containing the hazardous chemicals in the buffer tank is directly pumped by the vacuum pump to the scrubber, and the washed condensate is also pumped to the sewage treatment plant. The exhaust gas from the scrubber is filtered by activated carbon and discharged to the atmosphere.
The cleaning system is also very simple and easy to operate. When the tanker is to be cleaned, first open the opening in the lower part of the tanker, then install the special adapter flange through the steam pipe, and connect the steam pipe. At the same time, connect a pipe to the buffer tank on the adapter flange at the bottom of the tanker. The top of the buffer tank is connected to a vacuum pump and is responsible for providing a vacuum to the buffer tank to draw steam and residue from the tanker. Install oil-water separation units, oil separators, scrubbers, and filters. Connect the pipe. The time for steam cleaning depends on the type of material quality remaining in the tanker. The condition of the tanker is checked before cleaning to determine the cleaning time.
Steaming starts and steam is turned off after some time. When waiting for the tanker to cool to a certain temperature, check the tank conditions to determine if the cleaning is complete. If there is any residue, continue steam cleaning for a while. During the vacuum pumping process, an inlet port is reserved at the top of the tanker to prevent vacuum pumping from working. When cleaning dangerous goods tankers, the sewage containing hazardous chemicals at the bottom of the buffer tank does not need to be directly centrifuged to the sewage treatment plant.
This cleaning system can be said to be designed specifically for hazardous chemicals tankers. How about, is it not bad? If you are interested in this cleaning system, you are welcome to consult the staff of China Automotive Network!
Head/Drive Pulley is located at the discharge terminus of the conveyor. It provides the driving force for the conveyor. In order to increase pulley life and traction, it often has a larger diameter than other pulleys.
In the conveyor belt system, a head pulley has power applied to it and an idler is a pulley that has no power. The head pulleys will cause the belt to move toward them, while the idler pulley simply turns over and allows the belt to move. The power can be derived from a motor or can be provided by hand. The larger the materials or goods that are moved by the conveyor built the pulley is powering, the stronger the motor or other power source will need to be that drives the head pulley.
