Embodiment Construction

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] like Figures 1 to 7 A water-making device for evaporating secondary condensate in the production of alumina is shown, wherein: comprising a heat exchange device 1, a mechanical stirring clarifier 2, a quartz sand filter 3, an anion and anion bed ion exchanger 4 and a mixed bed ion Exchanger 5; Evaporated secondary condensate 6 is first cooled by heat exchange device 1, then flocculated and removed in mechanical stirring clarifier 2, and then filtered through quartz sand filter 3, and then enters anion-and-yang bed ion exchanger 4 for chemical treatment. Desalination, and then enter the mixed bed ion exchanger 5 for chemical demineralization again, and the demineralized water that reaches the qualified index is supplied to each water point.

[0037] The evaporative secondary condensate 6 is connected with the heat exchange device 1 throu...

Abstract

The invention relates to a water production device for evaporating secondary condensate in aluminum oxide production, belongs to the technical field of secondary condensate utilization in an evaporation process, and solves the technical problems of high cost, water resource waste and the like of traditional water production from raw water. The solution is as follows: the device for producing water by using the evaporated secondary condensate in aluminum oxide production comprises a heat exchange device, a mechanical stirring clarification tank, a quartz sand filter, an anion-cation bed ion exchanger and a mixed bed ion exchanger, the mechanical stirring clarification tank comprises a support and a tank body arranged on the top face of the support, a mixing and stirring area is arranged on the upper portion of the middle in the tank body, a settling area, a filling area and a clarification area are sequentially arranged in an inner cavity, outside the mixing and stirring area, of the tank body from bottom to top, a stirring device is arranged in the mixing and stirring area, and a mud scraping device is arranged in the settling area. The device is simple in structure, secondary condensate in the evaporation process is fully utilized and treated, resources are saved, and waste is reduced.

Description

technical field [0001] The invention belongs to the technical field of the utilization of secondary condensate in an evaporation process, and specifically relates to a water-making device for evaporating secondary condensate in alumina production. Background technique [0002] Boiler water in power plants has high requirements for laboratory indicators, and demineralized water must be used. Demineralized water is the finished water obtained after removing suspended solids, colloids, inorganic cations, anions and other impurities in water. The current demineralized water production method is to use raw water (well water or river water, etc.), after being treated by desalination equipment, to make demineralized water that meets the boiler water index, heated and deoxidized by a deaerator, and then pressurized by a feed pump and sent to the boiler continuously. produce steam. The raw water desalination device is that after the raw water is mechanically stirred and clarified to...
