Abstract

The invention relates to a sludge treatment device and method, in particular to a sludge screw-type direct drying device and method and mainly aims to solve the technical problem that existing sludge treatment methods are low in treatment amount and high in cost. The sludge screw-type direct drying device comprises a feeding hopper, a screw conveyor is arranged at an outlet, a discharging port of the feeding hopper faces a feeding port of a spiral extrusion electric heating material dryer, an electric heater wraps the outside of the feeding hopper, a screw of a dryer is driven by a motor through a belt wheel, an exhaust pipe is arranged at the top of the dryer to be connected with a negative pressure material collector, and an outlet of the dryer is connected with the negative pressure material collector; an outlet of the negative pressure material collector is connected with a cyclone separator through a pipeline, the cyclone separator is fixed on a steel frame, a fan is arranged at the lower end of the cyclone separator and connected with a material bin, an air outlet of the cyclone separator is connected with a pulse deduster through a pipeline, and an air outlet of the pulse deduster is connected with a high-pressure fan and a chimney through pipelines. The sludge screw-type direct drying device and method mainly aims to dry and extrude sludge cakes formed by sludge after being mechanically press-filtered and dewatered into granular powder.

Description

technical field [0001] The invention relates to a sludge treatment device and a treatment method, in particular to a sludge screw-type direct drying device and a method. The invention mainly aims at the sludge cake after the sludge slurry is dewatered by mechanical pressure filtration, and then dried and extruded into granular powder. Background technique [0002] In recent years, my country has gradually paid more attention to the treatment of various types of sewage sludge. However, due to the problems of large stacking area, slow drying speed, and environmental pollution, even developed countries will be dehydrated in the past two years. There is no better way to bury the sludge in the soil, which shows that there is no breakthrough in the sludge treatment technology of foreign developed countries. In China, it is regarded as a scientific and technological project of the "13th Five-Year Plan", so it is necessary to find a new treatment process. After retrieval, Chinese p...
