Abstract

The invention discloses a high-dehydration-rate sludge drying method which comprises the following steps: firstly, sludge is put into a concentration tank, preliminary dehydration is carried out on the sludge, the concentration tank is mainly used for reducing interstitial water of the sludge, and the concentrated sludge still keeps flowability; injecting the concentrated sludge into a conditioning tank through a feeding device; starting a stirring device, stirring the sludge in the conditioning pool, and injecting a conditioning agent, a guiding agent and a breaking aid into the conditioning pool at the same time; treating the sludge treated by the modified wall breaking unit by a filter press to remove water in the sludge; feeding the sludge treated by the filter press into a sludge crusher through a screw conveyor, and crushing and scattering the sludge; finally, the crushed sludge is forcibly air-dried.

Description

technical field [0001] The invention relates to the technical field of sludge, in particular to a sludge drying method with high dehydration rate. Background technique [0002] In the daily production of enterprises, a large amount of production sludge will be produced along with the production. If the sludge is discharged directly without treatment, it will not only cause serious pollution to the environment, but also seriously damage the ecological balance. Therefore, sludge treatment is an important problem that enterprises must face in practice. [0003] At present, the sludge treatment has the following disadvantages: the sludge treatment process takes a long time, the water removal effect in the sludge is poor, and the production cost of the enterprise is increased. The sludge has a strong odor and is not convenient for sludge reuse. Contents of the invention [0004] In order to overcome the deficiencies of the prior art, the present invention provides a sludge dry...
