According to this configuration, the gap between the lid member 15 and the opening 12 is reliably sealed by the seal member 14 by disposing the lid member 15 in the closed position, so that the heat-treated fluid in the case 10 is opened to the opening 12. Can be prevented from leaking out of the case 10.
- the heat exchange device 1 drops a fluid to be heat-treated from the open portion above the case 10 into the case 10 and distributes and flows it in a liquid film along the outer surface of the heat transfer medium circulation pipe 30.
- This is a falling film type heat exchange device that exchanges heat with the heat transfer medium flowing through the heat transfer medium flow pipe 30.
- the piping of the heat exchanging part 41 is in an aligned state, and adjacent to the heat exchanging part 41 wound in a spiral shape of the heat transfer medium circulation pipe 30.
- the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Deformation is possible.
- the device of the present invention can be used in a wide range of fields as a heat exchange device that requires not only cooling of beverages and cooling of a source but also appropriate temperature adjustment.
- boilers are indispensable heat exchangers in various industrial fields. It is used in various places, from hot spring facilities to agriculture, industry, and home use. For example, when a cold spring is directly heated by a boiler, hot spring components (sludge adherence) are not only excessively costly for maintenance due to failure, deterioration, and adhesion of the boiler, but also shorten the boiler life. Therefore, the apparatus of the present invention is used in combination to supply high-temperature water from the boiler as a heat transfer medium and circulate between the boiler and the heat exchanger, thereby preventing boiler failure and improving fuel efficiency. Also, exhaust heat from the boiler can be used. Furthermore, CO2 can be reduced by treating the exhaust heat to lower the exhaust heat temperature, which can contribute to environmental conservation problems.
- the product after heat treatment can be immediately cooled, so that containers can be immediately packed and productivity is improved.
- rapid container packing prevents the flavor from being damaged. That is, the liquid heat exchanger can be used in a wide range of fields, and the application field can be expanded by changing the material of the apparatus.
