Hello, everyone, today the technical engineers at Works Chemical introduce a special dehydrating agent for coal washing. Sludge enhancers developed by Works Chemical enable deep dewatering of sludge; The special sludge synergist for coal washing is a chemical agent which can change the surface structure of sludge, reduce the surface load of sludge solid, reduce the specific surface area of sludge and destroy the structure of bacteria.

The main components of the special sludge enhancer for coal washing are inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent, sludge stripping agent, etc. The special sludge synergist for coal washing has the advantages of less dosage, low cost, breaking the bottleneck of sludge dehydration, achieving efficient concentration and dehydration, good treatment effect and high cost performance.

The special sludge enhancer for coal washing combined with the plate and frame mud press can reduce the moisture content of the sludge from more than 90% to 40%-60%, and fully realize the sludge reduction. After the sludge is conditioned with a special sludge enhancer for coal washing, the pressure of about 1.0MP is injected into the filter chamber of the filter press to efficiently filter out the free water in the sludge, and the sludge accumulates in the filter chamber to reach the design capacity of the filter press.

The final dryness of the press dehydrated sludge is closely related to the effect of chemical conditioning and modification, but also to the filling degree of the filter press chamber, the press pressure rate, the press pressure retention time, etc. The use of high pressure feeding and pressing can shorten the time of the whole press section and improve the production efficiency when the chemical conditioning achieves better results. Automatic discharge and reverse blowing of the filter medium (filter cloth) are completed at the same time, and the special sludge synergizer for coal washing can not only reduce the labor intensity of the control workers, but also improve the efficiency of the completion of the operation, and maintain the effect of the filter cloth intercepting sludge and permeation.
