Abstract

The invention discloses a water supply method and a system, in particular to a cooling water supply method and a system for equipment in the technical field of alumina. The method comprises the following steps: qualified condensed water obtained by mother liquor evaporation or autoclave digestion is sent to a soft water tank; the soft water tank sends the soft water to a plate type heat exchanger;the plate type heat exchanger carries out heat exchange on the soft water and the circulating water sent from a circulating water station; and the soft water after heat exchange is sent to mechanicalequipment needing cooling in an alumina plant for cooling. The invention is simple in composition, can be arranged near the operation places of the equipment, save construction investment and solve the problem that the pipelines are not suitable for laying due to long delivery distance. The invention can ensure the temperature and quality of the cooling water efficiently, realize cycle use of thecooling water and reduce consumption of the production water.

Description

technical field [0001] The invention relates to a water supply method and a water supply system, in particular to a cooling water supply method and a water supply system for equipment in the technical field of alumina. Background technique [0002] In alumina production, during the operation of equipment such as solution pumps, mechanical seals will generate heat due to friction, and need to be cooled with water to ensure the normal operation of mechanical equipment. Due to the different locations and quantities of mechanical equipment, the sources and supply methods of cooling water are also different. Some factories set up separate soft water stations to supply cooling water, while others use fresh water for production as cooling water for mechanical equipment. Generally, the cooling water demand of a single mechanical equipment is about 0.25m 3 / h, the flow rate is very small, the farther the equipment use point is from the circulating water station, the greater the pres...
