Steam pipe hydrophobic recovery system suitable for severe cold regions

Abstract

The invention discloses a steam pipeline drainage recovery system suitable for severe cold regions, which comprises several drainage recovery units connected with the steam pipeline along the way, and the drainage recovery unit includes a steam trap group connected with the steam pipeline in sequence, a condensed water recovery The device and the condensed water pipeline; wherein, each condensed water pipeline is collectively connected with a condensed water main pipe, and the condensed water main pipe and the steam pipe are laid in the same heat preservation structure. The steam pipeline drainage recovery system connects several drainage recovery units along the way of the steam pipeline, gathers a small amount of condensate recovered in each drainage recovery unit into the condensate main pipe, and lays the condensate water main pipe and the steam pipe outside In the same insulation structure, it solves the phenomenon of difficult condensed water recovery and easy freezing caused by the small amount of condensed water generated per unit time and the low flow rate of condensed water; at the same time, it uses the heat tracing principle of the steam pipe's own heat and adopts low-cost settings to achieve Efficient recovery of condensate.

Description

technical field [0001] The invention relates to a condensed water recovery system discharged from a steam pipeline steam trap group, in particular to a steam pipeline drainage recovery system suitable for severe cold regions. Background technique [0002] In order to prevent the occurrence of steam resistance and water hammer, the steam pipe network in the factory area, especially the low point of the saturated steam pipe network, needs to be equipped with steam traps to discharge the steam condensate in the steam pipe. At present, the condensed water discharged from the steam pipe trap group in the factory area of ​​most metallurgical enterprises is directly discharged into the drainage ditch of the factory area or directly into the environment. The temperature of the condensed water is relatively high, and the direct discharge of the high-temperature water will, firstly, damage the environment; secondly, cause waste of energy. [0003] In addition, some metallurgical fact...
