Technical Field

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger.

[0003] According to announcement number CN203928857U, a condensate discharge device is disclosed, which is mainly composed of a heat exchanger water receiving pan, a heat exchanger drain pipe, a flue water receiving pan, a flue drain pipe, a connecting pipe, a drain valve and a drain pipe. The heat exchanger located at the lower layer is connected to the top pipe of two upwardly protruding vertical pipes. When the accumulated water in the condensate discharge device can pass over the top pipe, the condensate generated by the heat exchanger and the condensate generated by the flue can be discharged to the outside of the machine through the drain pipe in time. The condensate in the heat exchanger water receiving pan of the heat exchanger located at the upper layer is discharged to the flue through a vertical pipe and a top pipe, and then merged with the condensate generated by the flue, and then downward through the flue drain pipe to merge with the condensate in the heat exchanger drain pipe of the heat exchanger located at the lowest layer, and then discharged to the outside of the machine through the top pipe of the heat exchanger located at the lowest layer.

[0004] However, the above condensate discharge device has the following defects:

[0005] Condensate is discharged by gravity, which directly uses gravity to discharge the condensate. This method requires the inclination of the equipment and the correct outlet design, which can easily lead to problems such as poor drainage and excessively high water levels. It is inconvenient to adjust the drainage flow and direction, and the drainage airtightness is poor. The condensate is mixed with steam and the temperature is high. When discharged, the heat and condensate cannot be recycled well. Since the water quality of the condensate is good, direct discharge will cause waste of resources and poor drainage effect.
