No matter coal slime, raw coal, washing and dressing coal, brewer's grain, liquor's grain, Chinese medicine dregs, bean dregs, sweet potato dregs, cassava dregs, wood chips, sawdust and other high wet material drying projects have all taken a leading position in environmental protection management in terms of public opinion and policy. At present, the common problem is how to solve the heat source? How is the exhaust treated? How does the project pass the eia?

  This paper mainly aims at answering the questions about heat source and dust removal in slime drying. In terms of the relevant requirements of slime drying production line for plant area and structure, the specific requirements shall be based on the daily treatment amount of slime drying, the initial moisture content of slime and the specific requirements of dry material moisture content. The equipment model shall be provided after calculation.
  Q: What is the heat source for the slime dryer?Coal is no longer allowed.
  A: At present, the new type of coal slime dryer uses the heat source belongs to clean energy, natural gas, steam, biomass fuel can be used as heat source. If there is steam, steam drying coal slime is more environmentally friendly, and the cost is lower.
  Q: Can a slime dryer pass an eia?
  A: At present, the wet and dry mixed multi-stage dust removal system adopted by the slime dryer has high dust removal efficiency, and dust and carbon and sulfur oxide pollution can be effectively controlled to ensure the environmental impact assessment.
  Zhengzhou Dingli will be based on the existing resources of customers or convenient resources for slime drying production line equipment configuration, its basic foothold and starting point is efficient heating and lower fuel costs. If the customers have cheaper natural gas resources, the configuration of gas-fired hot blast furnace or gas producer;If the customer has a wealth of steam preheating resources, planning for the customer column type steam dryer, recovery of steam and so on.
  Zhengzhou Dingli adopts the multi-stage dust removal system of wet and dry, cyclone dust collector + bag-type dust collector + wet dust collector, cooperate with the clean heat source system, improve the dust removal efficiency, reduce the cost of tail gas treatment, ensure that the project has passed the environmental assessment, high efficiency, energy saving and continuous production.
