Integrated self-condensation drainage device

Abstract

The invention provides an integrated self-condensation drainage device. The device comprises a shell, a steam pipeline, a condensate pipeline and a drainage pipeline, wherein the steam pipeline, the condensate pipeline and the drainage pipeline are all arranged in the shell, the first end of the steam pipeline is in communication with the exterior of the shell, the second end of the steam pipeline is in communication with the first end of the drainage pipeline, the second end of the drainage pipeline is in communication with the first end of the condensate pipeline, the second end of the condensate pipeline is in communication with the exterior of the shell, a drainage valve is arranged on the drainage pipeline, and a cooling assembly is arranged on the condensate pipeline. The device is installed at the low point or the tail end wherein a condensate is generated of an existing steam pipe, the steam pipeline is in communication with the existing steam pipe, the condensate pipeline is in communication with an existing condensate pipe, the condensate generated in the existing steam pipe enters the steam pipeline and flows through the condensate pipeline through the drainage valve of the drainage pipeline to be drained into the existing condensate pipe, when the condensate is flash-evaporated into steam through the drainage valve to enter the condensate pipeline, the condensate is condensed again into condensate through the cooling assembly, and thus the steam generated through flash evaporation can be effectively treated, and the water hammer phenomenon is reduced.

Description

technical field

[0001] The invention relates to a condensation hydrophobic structure in the chemical production process, in particular to an integrated self-condensing hydrophobic device. Background technique

[0002] In chemical plants, there are multiple steam specifications, such as: 9.8Mpa, 4.1Mpa, 2.5Mpa, 1.4Mpa, 0.6Mpa, etc. Each specification of steam may produce condensate, and the condensed water in the steam pipeline will cause the steam to be heated. Even, the latent heat of steam will be lost, and it may cause corrosion to equipment and pipelines, and may even cause water hammer, icing, vibration and other phenomena in the steam pipeline. Steam traps can remove non-condensable gases such as steam condensate and air in steam heating equipment or steam pipelines without leaking steam. It is mainly installed in places where condensation may occur in steam pipes, including low points of steam, steam heating or heat tracing ends, etc. All steam traps have back press...
