Solar Polysilicon Waste Mortar Treatment Filter Press

In the production process of solar polycrystalline silicon ingots, monocrystalline silicon rods, silicon wafers, solar cells, and hydrogen fuel cells, a large amount of waste mortar is generated from the cutting of silicon wafers, and a large amount of silicon mud waste will be generated during the on-line recycling and processing of waste mortar.

1. The harm of solar polysilicon waste mortar

In the production process of solar polycrystalline silicon ingots, monocrystalline silicon rods, silicon wafers, solar cells, and hydrogen fuel cells, a large amount of waste mortar is generated from the cutting of silicon wafers, and a large amount of silicon mud waste will be generated during the on-line recycling and processing of waste mortar. The large amount of silicon carbide and polyethylene glycol contained in the silicon sludge waste still has recycling value; in addition, if the silicon sludge waste is not treated centrally, it will cause serious pollution to the environment.


2. Application of solar energy polysilicon waste mortar treatment filter press

Common processing methods in the industry:

After washing with water, a part of the polyethylene glycol is extracted and then treated by simple and crude methods such as burying and discarding. This not only causes a great waste of resources, but also causes serious pollution to the environment.

Sudong filter press recommendations:

Recycling the silicon sludge after the membrane filter press is fed and squeezed has greater economic benefits and can reduce environmental pollution.

The main difference between the diaphragm filter press and the current ordinary chamber filter press is the use of elastic diaphragms on both sides of the filter plate to form a whole. During operation, when the feeding is finished, the high-pressure fluid medium can be injected between the filter plate and the diaphragm. At this time, the entire diaphragm will swell and squeeze the filter cake to achieve further dehydration and reduce the water content of the filter cake.
