The invention discloses a sludge dewatering and drying integrated device, comprising an outer grid, a drum, a steam conduit and a power device, wherein the outer grid is cylindrical; the drum is arranged in the outer grid; the steam conduit is arranged in the drum; the inner surface of the drum is provided with an inner screw panel; the outer surface of the drum is provided with an outer screw panel; threads of the inner screw panel and the outer screw panel are reversely arranged; the internal space of the drum is communicated with the internal space of the outer grid through a gap between the side of a cone at one end of the drum and the drum; a sludge outlet is arranged below the other end of the drum; the advancing direction of the thread of the outer screw panel is toward the cone; the cone is arranged at the bottom surface of one end of the outer grid; the top of the cone extends into the drum; the diameter of the bottom surface of the cone is smaller than that of the drum; a sludge inlet is formed at the other end of the outer grid; and the power device is connected with the drum. The sludge dewatering and drying integrated device disclosed by the invention has the characteristics of small occupied space, low noise, low power dissipation and high dewatering rate.
Description
technical field [0001] The invention belongs to the technical field of sludge dewatering, and in particular relates to a device integrating sludge dewatering and drying. Background technique [0002] Sludge dehydration and drying is a sludge treatment method that removes water from fluidized primary, concentrated or digested sludge and converts it into semi-solid or solid sludge. After dehydration, the moisture content of the sludge can be reduced to 55% to 80% (depending on the nature of the sludge and sediment and the efficiency of the dewatering equipment). The further dehydration of sludge is called sludge drying, and the moisture content of dried sludge is less than 10%. Dehydration methods mainly include natural drying method, mechanical dehydration method and granulation method. Natural drying method and mechanical dehydration method are suitable for sewage sludge. [0003] The existing sludge dewatering equipment mainly includes the following types: [0004] ...
