Water seal scraper conveyor can be used for ash transportation in waste incineration power plants. The following is the relevant explanation:
### Working Principle
- The water seal scraper machine is mainly composed of closed water trough, scraper chain and driving device. The scraper chain runs in the water tank, the ash enters the water tank from one end, and is pushed by the scraper chain to move along the bottom of the water tank, in the process of moving, the ash is always in the water-sealed state, and finally discharged from the other end.
### Advantages for ash transportation
- **Efficient and stable**: It can continuously and stably convey ash, adapting to the characteristics of waste incineration power plants that produce ash in continuous operation, ensuring that ash is conveyed in a timely and effective manner without blockage or flow breakage, and helping to maintain the normal operation of the entire power generation system.
- **Good sealing**: The water seal structure can effectively prevent dust from being generated during the ash transportation process, avoiding pollution of the environment caused by dust outward, and also preventing the leakage of hazardous gases, which is crucial for the environmental protection requirements of waste incineration power plants.
- **Good cooling effect**: the ash after waste incineration has a high temperature, the water in the water seal scraper machine can cool the ash and reduce the temperature of the ash, which is conducive to the subsequent processing and transportation, but also reduces the thermal damage to the equipment, prolonging the service life of the equipment.
- **Less wear and tear**: under the lubrication of water, the friction between the ash and the scraper and trough body is reduced, compared with other dry conveying equipment, the water seal scraper has a lower degree of wear and tear, which reduces the cost of maintenance and replacement frequency of the equipment, and improves the reliability and operational efficiency of the equipment.
### Application Scenarios
- In waste-to-energy power plants, the water seal scraper is usually used to convey the high-temperature ash discharged from the incinerator to the ash storage silo or subsequent processing equipment. It can be installed at the bottom of the incinerator and connected to the slag discharge port of the incinerator to transport the ash away in time to ensure the normal slag discharge of the incinerator.
Overall, because of its many advantages, it has been widely used in ash transportation in waste incineration power plants.
