Abstract

The invention discloses a dehydration anhydration device and aims to provide a dehydration anhydration device which can effectively carry out anhydration treatment on lots of water-containing sludge and has advantages of continuous and stable anhydration process, high anhydration efficiency, high degree of overall anhydration uniformity and good anhydration effect. The dehydration anhydration device comprises a rack, a horizontally-arranged anhydration main-cylinder and a dry sludge receiving part. The anhydration main-cylinder is provided with a sludge feed inlet, a hot flue gas inlet and a wet flue gas outlet. The rack is provided with a bearing pedestal which is equipped with a matched rotor spindle. A spindle drive motor which is connected with the rotor spindle through a speed reducer is arranged on the rack. The lower part of one end of the anhydration main-cylinder, far from the sludge feed inlet, is provided with a sludge discharge hole. The rotor spindle is equipped with multiple stirring catch bars. The invention has the following beneficial effects: energy utilization is reasonable; the anhydration process is uniform, continuous and highly efficient; the device has a secondary anhydration device and the anhydration effect is obvious; and the device has a cleaning structure which can help guarantee work efficiency after anhydration and prolong service life of the device.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, in particular to a dehydration and drying device. Background technique [0002] A large amount of sludge will be produced in the process of sewage treatment, and the treatment method of these sludges is usually incinerated in a furnace, and the hot flue gas discharged after incineration is about 300 to 400 degrees. Before sludge incineration, the sludge needs to be dried. The initial water content of the sludge is about 75% to 85%. After the treatment, the water content is greatly reduced, and then the incineration operation can be carried out. Although the current sludge drying treatment methods can achieve a certain degree of dehydration and drying, there are still many deficiencies in terms of drying efficiency, drying degree, and drying uniformity. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a method tha...
