Abstract

The invention discloses a sludge heating and drying device, and aims to the sludge heating and drying device which is capable of carrying out drying treatment on sludge with high moisture content, continuous and stable in drying process, high in drying efficiency, high in integral drying uniformity, and good in drying effect. The sludge heating and drying device comprises a rack, a transverse drying main barrel and a dried sludge receiving part, wherein a a sludge feeding hole, a hot flue gas inlet and a wet flue gas inlet are formed in the drying main barrel; a bearing base is arranged on the rack; a matched rotor main shaft is arranged on the bearing base; a main shaft drive motor which is connected with the rotor main shaft by a speed reducer is arranged on a base frame; a sludge discharge hole is formed in the lower part, far from one end of the sludge feeding hole, of the drying main barrel; and a plurality of stirring and pushing rods are arranged on the rotor main shaft. The sludge heating and drying device has the beneficial effects that: energy resources are reasonably utilized; the drying process is uniform, continuous and efficient; the drying effect is obvious as a secondary drying device is provided; and the working effect in the future can be guaranteed and the service life can be prolonged as a clearing structure is provided.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, in particular to a sludge heating 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 ...
