Technical Field
The invention relates to the technical field of heat energy conversion equipment, in particular to a visible gas-liquid direct contact type condenser.
Background
Direct contact condensers are well known and widely used in various industrial processes, such as open water heaters, petroleum refining processes, geothermal energy exploitation seawater desalination, and solar energy utilization. Compared with an indirect contact condenser, the direct contact condenser has multiple advantages as a direct contact heat exchange device: low cost, easy separation, high heat transfer rate, and low tendency to scale and corrode.
In experimental research and practical application, in order to observe the gas-liquid heat exchange process in the heat exchanger, the heat exchange device needs to be made of transparent materials, and organic glass is generally adopted. This places higher demands on the pressure-bearing and sealing properties of the device, especially the inlet and outlet portions.
In the actual use process, if the structural design of the heat exchanger is unreasonable, not only is the heat exchange efficiency low, but also strong noise and vibration can occur, and even the structure of the equipment can be damaged. How to reduce the damage to equipment caused by the phase change of the fluid and how to improve the heat transfer efficiency of the direct contact heat exchanger with the phase change is a core problem in the field.
