Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recycling devices, and more specifically to a waste heat recycling device for a screw extruder. Background Art

[0002] Energy conservation, emission reduction and comprehensive energy recycling are major strategic tasks faced in the process of industrial production development. At the macro level, it is required to adjust the industrial structure and layout, and integrate the development concept of energy conservation, emission reduction and comprehensive energy recycling into all aspects of the entire production. Recycling and utilizing industrial waste heat is an important measure to save energy, protect resources, protect the environment and promote circular economy. Comprehensively utilizing existing waste heat resources and adopting advanced waste heat recovery technology to make full and reasonable use of this part of waste heat can greatly reduce the comprehensive energy consumption of enterprises, thereby improving their competitiveness and promoting their sustainable development.

[0003] After receiving the heat transmitted by the screw extruder, the existing waste heat recycling device will eventually transfer the heat to the inside of the water tank and heat the cold water. However, the existing waste heat utilization equipment will leak when the connection with the air compressor is not reliable, resulting in serious heat loss; and when the collected heat is transmitted to the water tank through the pipeline, a large amount of heat energy is lost because the water tank does not have a good insulation structure.
