Problems solved by technology

This method is only suitable for cooling concrete in small areas and does not require high water flow and water temperature. Since the return water temperature of the cooling water is still far lower than the temperature of normal temperature water, the cooling return water is discarded or discharged to the foundation pit to form a large Waste, it will increase the drainage pressure of the foundation pi

Abstract

The invention relates to a mass-concrete cooling water recycling device and method. The mass-concrete cooling water recycling device comprises a refrigerating system, a circulation water tank, a cold water conveying and supplying system and a backwater collecting tank, wherein the refrigerating system is communicated with the circulation water tank, and the circulation water tank is communicated with the cold water conveying system. The cold water conveying system supplies cooling water for a mass-concrete cooling area, the cooling area discharges backwater into the backwater collecting tank, and then the collected cooling backwater is conveyed into the circulation water tank. The device adopts the technical measures that the water collecting tank recovers the mass-concrete cooling backwater in a centralized mode and a water mixing tank fully mixes catchment water and the like, so that the recycle of recovered cooling water is realized, the water resource and power consumption is reduced, the equipment wear is reduced, and the actual efficiency of refrigerating equipment is increased. The mass-concrete cooling water recycling method has the advantages of energy saving, environmental protection, economy, high efficiency, convenience and reliability.

Description

technical field [0001] The invention relates to a device for collecting and utilizing concrete cooling return water, in particular to a device for reusing large-volume concrete cooling water. The invention also relates to a method for using the device to realize reusing large-volume concrete cooling water. Background technique [0002] In the construction of construction projects, in order to ensure the construction quality of large-volume concrete and prevent concrete temperature cracks, it is generally necessary to use the cooling water pipes laid during the pouring process to pass cold water for cooling after the concrete pouring is completed. Concrete water cooling is usually used to supply water by a single mobile refrigeration unit, water cooling in partitions, and the cooling return water is discharged from the end of the concrete internal pipe to the drainage ditch or foundation pit. This method is only suitable for cooling concrete in small areas and does not requir...
