Coal drying refers to the process and process of drying and upgrading the coal with a large water content such as coal or coal slurry, or raw coal or blue carbon. The final moisture content is at the customer's request. As a standard, various water contents such as 5% or 10% can be used. The current technology of wet coal drying has developed relatively mature.
Coal drying in the past, mainly based on coal burning, although the cost of this type of wet coal drying is lower, but the pollution problem caused by the current ecological civilization construction caused the production line to be stopped, the project rectification And the corresponding penalties bring unpredictable losses to the company. Thus, wet coal slurry drying is achieved in a more environmentally friendly and low-cost manner.
Dingli started from the two sources of pollution sources and pollution control, clean heating and multi-stage dust removal and purification, launched an energy-saving and environment-friendly wet coal dryer. This type of wet coal drying prevention has quickly gained favor from the market, and it has also promoted the expansion of its overseas export business.
Compared with the traditional tumble dryer, the energy-saving and environment-friendly wet coal dryer has obvious upgrades and technical improvements in the heat source equipment and exhaust gas discharge equipment, and the drying structure of the tumble dryer is also slightly adjusted, mainly Improvements have been made in sealing and insulation technology, and the heat utilization rate has increased by 13%; while the heat source is mainly based on clean energy, such as natural gas, gas and other fuels, and customers with steam resources are recommended to use steam as the coal drying machine. The cost is lower and more environmentally friendly; while the exhaust emission system is mainly based on multi-stage dust removal and purification devices, and the exhaust gas with high dust content is purified and treated to meet the requirements of environmental impact assessment.
