At present, the fine processing of minerals often emphasizes higher purity and finer particle size, such as calcium carbonate, kaolin, titanium dioxide, bentonite, etc., and even reaches the micron or nanometer level, so the formation of slurry solid-liquid separation is more difficult, often can not be filtered, not dry, filter cake dense, high moisture content, the need for a spade frame and other phenomena, seriously affecting production efficiency. So, in the actual production process, how to solve the problem that the plate and frame filter press is not formed? The most important thing is to reduce the moisture content in the sludge. Works Chemical has developed its own deep dewatering agent for high moisture content sludge.
Works Chemica- Manufacturer of sludge conditioner, sludge dewatering enhancer
Sludge deep dewatering agent can effectively reduce the moisture content of the sludge, dehydrate the sludge more deeply, and finally reach the plate and frame press to press the mud into chunks. Sludge deep dehydrating agent is a kind of chemical agent which can change the surface structure of sludge, reduce the solid surface load of sludge, reduce the specific surface area of sludge and destroy the structure of bacteria. The main components of sludge deep dewatering agent are inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent, sludge stripping agent and so on.
The sludge conditioned by the sludge deep dehydrating agent is injected into the filter chamber of the filter press at a pressure of about 1.0MP, which is conducive to the free water in the sludge. After the accumulated sludge in the filter chamber reaches the design capacity of the filter press, it enters the high-pressure press section. The dryness of the dehydrated sludge is closely related to the effect of chemical conditioning and modification, as well as the filling degree of the filter chamber, the pressure boost rate and the pressure holding time.
When the chemical conditioning sludge deep dewatering agent achieves better effect, the high pressure feeding and high pressure pressing can shorten the time of the whole pressing section and improve the production efficiency. Automatic discharge and backblowing of filter material (filter cloth) are completed at the same time, which can reduce the labor intensity of the controller, and improve the efficiency of the completion of the action, and maintain the effect of the filter cloth to intercept sludge and permeable water.
