Abstract

The invention discloses an anode material of an electric / high-voltage coupled elastic press. It is a braided fabric obtained by mixing 30-60% carbon fiber and 40-70% polypropylene fiber or polypropylene fiber, that is, carbon fiber composite material cloth; the resistivity of carbon fiber is 36-144 ohm meters, and the tensile strength is 3530 Carbon fiber with ‑4410Mpa, denier 400‑700g / 1000m, flammability UL94V‑0, halogen content Cl<900, Br<900, Cl+Br<1500. The carbon fiber composite cloth can be installed behind the filter cloth of the anode filter frame of the conventional plate and frame filter, or the carbon fiber composite cloth can be directly replaced by the filter cloth of the anode filter frame, connected to the positive power supply, and used as an anode. In the present invention, the carbon fiber composite material is used as the anode material, and the electric conductivity is controllable, the cost is low, the service life is long, the energy utilization rate is high, and the installation mode is flexible.

Description

technical field [0001] The invention belongs to the technical field of sludge dewatering, and relates to an anode material of an electric / high-voltage coupled elastic press and an installation and use method thereof. Background technique [0002] In order to make urban sludge meet the subsequent disposal requirements, many sludge treatment companies use plate and frame filter press for dehydration. The traditional plate and frame filter press conditioning method is to add 5% to 10% ferric chloride, 20% to 30% quicklime and other inorganic conditioners on the dry basis of sludge for conditioning. This conditioning technology does not really achieve the purpose of sludge reduction, and the calorific value of sludge is further reduced. [0003] Sludge electric dehydration is a method of dehydrating sludge by applying an electric phenomenon by applying a DC voltage. The electrokinetic phenomenon refers to the phenomenon produced by the relationship between the movement of the ...
