41 results about "Water right" patented technology

Water right in water law refers to the right of a user to use water from a water source, e.g., a river, stream, pond or source of groundwater. In areas with plentiful water and few users, such systems are generally not complicated or contentious. In other areas, especially arid areas where irrigation is practiced, such systems are often the source of conflict, both legal and physical. Some systems treat surface water and ground water in the same manner, while others use different principles for each.

Device and method for preventing copper wires from being oxidized in production of enameled wires

The invention provides a device and a method for preventing copper wires from being oxidized in the production of enameled wires. The device comprises an annealing furnace and an annealing pipe penetrating the annealing furnace; wherein, a water tank is arranged at the outlet end of the copper wires of the annealing pipe; and the device is provided with one or more annealing pipes which are arranged in a tilted manner. The copper wires penetrate the water tank containing de-ionized water right from the annealing pipes of the annealing furnace, the temperature of the copper wires is equivalent to that of the annealing furnace, so that steam can be automatically generated when the copper wires are in contact with the de-ionized water; and the steam enters the annealing furnace via the annealing pipe, thereby preventing the copper wires from being oxidized and ensuring that the vapor entering the annealing pipes is continuous, stable and sufficient. The enameled copper wires produced by the invention have the advantages of bright surface and stable voltage performance, improves the quality and reduces the reject rate; as the steam generation device using the waste heat of exhaust gas is not used, and the de-ionized water used for cooling and rinsing is also used for sealing the annealing pipes on the outer wall of the annealing furnace at the same time, the invention greatly simplifies the production equipment of enameled wires, reduces the cost of installation and maintenance and ensures the safe operation, energy conservation and environmental protection.
