Supply Fu Hang FH100 saving sludge drying equipment

1.1 saving sludge drying equipment works After mechanical dewatering (water content of about 60%) of the sludge is placed in the greenhouse, the use of solar evaporation of sludge in the water, you can get 25-30% of the dry of dirt mud, sludge dewatering in the greenhouse there are two main drying process: (1) radiation drying. Saving sludge drying equipment to dry air as a heat carrier directly convert solar energy into thermal energy stored in air can air temperature, with hot air to the sludge temperature, its internal moisture to the surrounding air to accelerate evaporate, thereby increasing the sludge surface air humidity, and even saturated; (2) to the hot water circulation heating. Then by natural circulation and hot air scouring, the wet air temperature is discharged, so that the humidity sludge from the original surface saturated into a non-saturated, thus contributing to further internal moisture evaporation sludge into the surrounding air. In order to enhance the thermal insulation capacity of collector efficiency and greenhouse operation in the use of sludge stirring wheel flipped tile in the geothermal hot water circulation system or increase forced ventilation to improve the efficiency of evaporation. Energy-saving advantages of 1.2 sludge drying equipment (1) energy and natural drying sludge drying equipment (air dried) compared to its main advantage is that can greatly shorten the drying time and energy-saving sludge drying inside a greenhouse equipment odorous sludge drying process produces easily and effectively collect centralized treatment. The use of ground source heat pumps so that the water temperature is 1: 4.5 ratio increase water temperature, continuous heating to the bottom of the sludge. (2) Energy sludge drying equipment and drying device using conventional energy compared with the following advantages: ① to save fuel: Because the drying process basically does not consume fossil fuels. ② reduce the pollution of the environment: our air pollution, mainly from the coal, oil and other combustion gases and soot emissions, the use of energy-efficient sludge drying equipment, saving fossil fuels, it also can ease the pressure on the environment. ③ low operating costs on the initial investment, the solar geothermal energy and conventional energy Drying little difference between the two. However, the system is running, its fuel costs using conventional energy drying devices is very high. The use of energy-efficient sludge drying equipment, equipment investment (initial investment) difference between the two is small, but energy-sludge drying equipment in addition to the fan ground source heat pump consumes a small amount of power, the solar energy is free. (3) Energy sludge drying equipment belongs in various parts of the operating temperature low, simple, safe and reliable.
