Dingli's new low-temperature steam slime dryer technology is an environmentally friendly and water-saving technology. It is also an ideal clean coal mud technology project in China's water-poor areas and ecologically fragile areas.

  China's coal resources and water resources are reversed. The areas with abundant coal resources are also underdeveloped areas with fragile ecological environment and lack of water resources. Due to the difficulty in transportation, the construction of coal mines with power plants has become a trend, and the utilization of coal slurry drying technology has been completed. The steam drying is fully in line with the integration and large-scale construction of national coal conversion projects, coal chemical projects and washing and by-products. Technical environmental friendliness and water saving characteristics are industrial policy requirements that take precedence over economic considerations. The low-temperature coal slurry drying process involves only physical drying and mechanical extrusion.The steam drying process does not require process water, nor does it produce chemical waste water or waste gas. It is a typical water-saving and environmental protection project. The low temperature slime drying project is also an environmentally friendly project, which is characterized by environmental protection in production processes and environmental protection of products. There is no solid waste discharge during the production process. No dust or noise is emitted during the drying process, and the discharge requirements are met. Evaporation of water can collect water for heating or coal washing plant. The water after steam condensation is returned to the power plant through the return pump to achieve recycling. Achieving zero emissions, producing products --- type coal as a fuel combustion, its NOX, SO2 emissions are reduced, and thermal efficiency is improved. Therefore, the use of steam coal slurry drying technology in ecologically fragile, water-stressed, and re-construction is an ideal technology. It is an important project to realize diversified energy in the coal industry and develop the industry upstream and downstream.
