Problems solved by technology

The technology of using industrial waste heat to generate electricity is relatively mature, but the technology of using industrial waste heat for heating is relatively weak. The purpose of industrial waste heat reuse is not only to convert the waste heat wasted by factories into considerable economic resources, but also to convert this resource into heating and cooling. services, improve the quality of life of the people, and provide renewable energy, which will have a significant and far-reaching impact on the country's energy conservation, emission reduction, and circular economy

Abstract

The invention discloses a factory circulating cooling system and a cooling water reutilization system thereof. The factory circulating cooling system comprises a cold water pump unit, a water feeding header pipe, a water returning pipe, a cooling device and a cold water pool which are connected in sequence, wherein the cold water pool is connected with the cold water pump unit; a plurality of branch pipelines connected in parallel are arranged between the water feeding header pipe and the water returning pipe; each branch pipeline corresponds to at least one to-be-cooled device and is provided with a signal acquiring module; each signal acquiring module is connected with a control module; the control module is connected with the cold water pump unit. The cooling water reutilization system is connected with the factory circulating cooling system and comprises a water source heat pump unit, a heating system and an air conditioning system. The factory circulating cooling system disclosed by the invention is used for concentrating cooling water afterheat of the circulating cooling system in an overall factory so as to supply heat and provide refrigeration service, so the factory circulating cooling system can be applied to heating and air conditioning of a large building area, and the consumption of heat energy or electric energy can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of cooling of factory production equipment, and in particular relates to a factory circulating cooling system and a cooling water reuse system thereof. Background technique [0002] At present, the cooling water of production equipment (such as steelmaking furnaces, rolling mills, oil-water plate heat exchangers for presses and oil-water plate heat exchangers for quenching oil, etc.) in factories (such as thermal processing plants and steel mills) is mostly After being cooled by the cooling tower, it is recycled, resulting in a large amount of waste and loss of heat energy; and because the circulating cooling system of the production equipment in the factory is mostly scattered nearby, it is not conducive to the centralized utilization of the waste heat of the circulating cooling system in the entire factory. [0003] With energy conservation and emission reduction listed as a "hard indicator" for assessing ...
