Low-Cost and Efficient Coke Oven Waste Heat Recovery System Hot Product 2021 Provided Energy Saving

      Comprehensive Utilization of Waste Heat Drying System     System IntroductionAt present, the direct emission of high temperature flue gas, steam occurs in lots of printing and dyeing factories, power plants,which is a great waste of thermal energy. At the same time, there is a need for the drying of sewage sludge or other materials, which will consume a lot of fuel to supply heat. It will have great significance to reduce the environmental pollution and to alleviate economic pressure of enterprises by making effective use of the waste heat to dry the wet materials. Different factories are with different tail gas temperature, most of them is from 120ºC to 500ºC.   Process FlowThe scheme for maximizing the utilization of system thermal energy can be designed as per different material, waste heat temperature and waste heat flow.Cases 1: 200T/D Sludge Processing Project for one of Dalian Petrochemical Companies, and exhaust flow: 750000 Nm³/h; exhaust temperature: 135ºC; Our design is to use three sets of VS 4 x 32m dryer, which have been put into production.Case 2: 4T/D Sludge Processing Project for one of Shanghai dyeing factories, exhaust flow: 10000Nm³/h, exhaust temperature:180ºC; Our design is to use VS 2 x 5m intermittent dryer, which has been put into production.
