Sludge heating and drying system and method thereof

Abstract

The invention discloses a sludge heating and drying system. The sludge heating and drying system comprises a pretreatment mechanism, a transmission mechanism and a drying mechanism, wherein the pretreatment mechanism comprises a dehydrating cavity and a dispersing cavity, a dehydrating drum and an extrusion device are arranged in the dehydrating cavity, a tilting table and a dispersing device are arranged in the dispersing cavity, and the drying mechanism comprises a drying box body and a heating device. The drying method comprises the following steps: (1) carrying out primary dehydration treatment on sludge; (2) carrying out dispersion treatment on the sludge; (3) carrying out drying treatment on the sludge; and (4) cleaning, checking and repairing. The sludge heating and drying system disclosed by the invention is simple in structure and strong in practicability, most of sewage in the sludge is removed by virtue of the dehydrating cavity, then the dispersion treatment is carried out on the sludge extruded into blocks by virtue of the dispersing cavity, working pressure of the drying box body is reduced, sludge drying effect and sludge drying quality are improved, water resource is saved, and comprehensive utilization rate is improved.

Description

technical field [0001] The invention relates to a sludge heating and drying system and a method thereof. Background technique [0002] The process of urbanization in our country is in the stage of accelerating, and the situation of environmental pollution is also increasing. The sludge problem has become a major problem related to people's life. The annual sludge output in our country is very huge, and the weight is very alarming. At the same time, the total amount of sewage discharge in most cities is also in a trend of continuous and rapid increase. However, at the same time, the corresponding sewage treatment rate has not increased correspondingly, resulting in sludge discharge and stacking has become a new major pollution source. For the increasingly large amount of sludge, it has become the focus of our country's staff to take effective measures to dehydrate these huge amounts of sludge, so that it can achieve the goals of being environmentally friendly, reducing the a...
