Description

Technical Field

[0001] The utility model relates to the technical field of steam condensate recovery, and particularly relates to a steam condensate recovery device. Background Art

[0002] The steam condensate recovery device is a steam condensate recovery device that utilizes physical principles. When the user system operates normally, the condensate is discharged from the heat-using equipment, and is smoothly introduced into the flash tank through special hydrophobic devices such as a special hydrophobic device and a common network device. Secondary steam separation and utilization can be carried out as needed. The separated condensate is introduced into the return water tank by a heat pump, and after cavitation elimination treatment, the high-temperature condensate is directly sent into the boiler steam drum by a high-temperature water pump.

[0003] For example, the Chinese patent with the publication (announcement) number CN215982501U discloses an automatic circulating steam condensate recovery device, which includes a recovery pump body. The number of the recovery pump bodies is two, and pump covers are fixedly installed at the tops of the two recovery pump bodies. One side of the top of the pump cover is fixedly communicated with an intake pipe, and the other side of the top of the pump cover is fixedly communicated with an exhaust pipe.

[0004] Although the above technical solution solves the corresponding technical problems, the above technical solution still has the following defects:

[0005] The above technical solution does not have the function of preventing condensate from flowing back, and it is easy to cause steam to flow back when recovering steam condensate, thus reducing the practicability. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a steam condensate recovery device. By generating negative pressure with a steam condensate recovery pump and forming negative pressure in the steam condensate recovery pipe, under the action of negative pressure, the sealing plate can be moved away from the mounting ring, so that the steam condensate inside the steam condensate recovery pipe can be recovered. When the steam condensate recovery pump stops working, due to the elastic force of the sleeve spring, the sealing pad on the side of the sealing plate is driven to block the mounting ring, thus effectively avoiding steam from flowing back, and further improving the practicability of the utility model.

[0007] In order to achieve the above purpose, the main technical solutions adopted by the utility model include:

[0015] The present utility model at least has the following beneficial effects:

[0016] In the present utility model, a steam condensate recovery device is realized. A negative pressure is generated by the steam condensate recovery pump and a negative pressure is formed in the steam condensate recovery pipe. Therefore, under the action of the negative pressure, the sealing plate can be moved away from the mounting ring, so that the steam condensate inside the steam condensate recovery pipe can be recovered. When the steam condensate recovery pump stops working, due to the elastic force of the sleeve spring, the sealing gasket on the side of the sealing plate is driven to block the mounting ring, thereby effectively avoiding steam backflow, and further improving the practicability of the present utility model.
