Description

Technical Field

[0001] The utility model relates to the technical field of shell and tube heat exchange, in particular to a condensate separation mechanism for a shell and tube heat exchanger. Background Art

[0002] Shell and tube heat exchangers, also known as tubular heat exchangers, are partitioned heat exchangers that use the walls of the tube bundle enclosed in the shell as the heat transfer surface. This type of heat exchanger offers a simple structure, low cost, a wide flow cross-section, and easy scale removal. However, it suffers from a low heat transfer coefficient and requires a large footprint. It can be manufactured from a variety of structural materials and can operate under high temperatures and high pressures, making it the most widely used type.

[0003] The existing shell and tube heat exchanger can only simply collect the condensate during the heat exchange process, but cannot effectively remove the solid impurities in the condensate, resulting in the condensate being unable to be reused, which greatly increases the cost of use.

[0094] The sewage discharge assembly includes:

[0095] The sewage outlet 22 is provided on the filter housing 13 and is fixedly connected to the filter housing 13;

[0097] Before using the heat exchanger, prevent the condensate from flowing out directly through the drain port 22 during heat exchange, so that the condensate is not fully filtered.

[0098] Working principle: Before using the heat exchanger, manually pull the water retaining rod 21 to open the water outlet 20, so that the condensate after heat exchange can flow out of the heat exchanger smoothly, and then pull the drain rod 23 to close the drain outlet 22 to prevent the condensate from flowing out directly through the drain outlet 22 during heat exchange, so that the condensate is not fully filtered. After the preparation work is completed, the heat exchange can be started. The condensate is put into the cold inlet pipe 11 so that the condensate flows along the baffle 8 in an S-bend, so that it can contact with the liquid in the heat exchange tube 7 as much as possible, thereby realizing heat exchange. At this time, the heat exchange liquid is poured into the hot inlet pipe 3 and enters the heat exchange tube 7 through the hot tube cavity 5. The liquid in the heat exchange tube 7 will fully contact with the liquid sandwiched in the baffle 8, so that the two liquids can exchange heat. After heat exchange, the liquid entering from the hot inlet pipe 3 will enter the hot official cavity and go out along the hot outlet pipe 10. At this time, the condensate will flow along the The cold outlet pipe 12 enters the filter assembly to filter the solid impurities in the condensate. After the condensate enters the cold outlet pipe 12, the condensate will enter the filter assembly. Turning on the motor 16 makes the entire filter assembly, and adjusting the reducer 15, according to the size of the condensate flow rate, makes corresponding changes so that the filter can fully filter the condensate. At this time, the rotation of the motor 16 will drive the rotating rod 17 to rotate, thereby causing the filter on the rotating rod 17 to rotate, and the filter will filter the impurities on the filter. The filtered condensate will pass through the filter and enter the water outlet 20, thereby reaching the cold outlet pipe 12. The filtered impurities will be stored in the filter housing 13. You only need to pull the rotating rod 17, then push the water retaining rod 21, so that the water outlet 20 is closed, and then pull the sewage pull rod 23 to open the sewage outlet 22. Finally, pull the rotating rod 17 to drive the cleaning plate 19 in the filter element 18 assembly, so that the cleaning plate 19 carries the filtered impurities into the sewage outlet 22, and the filtration is completed.
