Abstract

The invention provides a sludge drying method and equipment. The method comprises the following steps: mixing liquid absorption particles with to-be-dried sludge slurry to obtain a mixture, and adsorbing liquid of the to-be-dried sludge slurry in the mixture by the liquid absorption particles; pressing the mixture, so that the liquid absorption particles are compressed and the liquid is discharged. According to the method, the liquid content of the dried sludge is reduced.

Description

technical field [0001] The present application relates to the technical field of sludge drying treatment, in particular, to a sludge drying method and equipment. Background technique [0002] There are roughly four ways for liquid to exist in sludge, among which interstitial water (free water) accounts for about 70% of the total water, capillary water accounts for about 20% of the total water, particle surface adsorption water and internal water account for about 10%. %. Sludge dehydration or drying has generally experienced four generations of technological development: (1) natural drying; (2) mechanical drying; (3) drying of polymer materials; (4) drying of nanomaterials, the degree of compounding of technologies is increasing. [0003] Mechanical drying relies on mechanical kinetic energy or thermal energy to achieve solid-liquid separation, mainly including screw dehydrator, belt filter press, plate and frame filter press, centrifugal dehydrator and rotary kiln dryer. ...
