Condensate recovery system for steam heating supply system

Abstract

The invention provides a condensate recovery system for a steam heating supply system. The condensate recovery system comprises a boiler, a condensate collection device, a steam conveying pipeline, a condensate recovery pipeline, a drainage valve and a reciprocation pump. A water outlet of the condensate recovery pipeline is connected with a water outlet of the condensate collection device. The steam conveying pipeline is connected with the boiler. The drainage valve is connected between the steam conveying pipeline and the condensate recovery pipeline so as to timely separate condensate generated in the conveying process of steam in the steam conveying pipeline and convey the condensate to the condensate recovery pipeline. The reciprocation pump is arranged on the condensate recovery pipeline, the horizontal position of the condensate recovery pipeline connected with a water inlet of the reciprocation pump is lower than or equal to the horizontal position of the condensate recovery pipeline connected with a water outlet of the reciprocation pump, and therefore accumulation of the condensate in the condensate recovery pipeline can be prevented.

Description

technical field [0001] The invention relates to a condensed water recovery system, in particular to a condensed water recovery system used in a steam heating system. Background technique [0002] Energy is an important material basis for human survival and development. The per capita share of energy, energy composition, and energy utilization rate are often used to measure the degree of modernization of a country. With the development of society and the progress of industry, the energy crisis has become a major problem that needs to be solved urgently in the world and is related to the survival of human beings. According to expert estimates, if the current energy consumption structure and speed are not changed, and new energy sources are not developed, all energy in the world will be exhausted 200-300 years from now. Therefore, effective energy conservation has become one of the cores of global energy research. [0003] As a clean and safe energy carrier, steam is widely u...

Problems solved by technology

[0005] Because in actual application, the level of the condensed water recovery pipeline 21 may be different, that is, the horizontal position of some pipelines is relatively high or in a long distance, the condensed water recovery pipeline is at the same horizontal position, resulting in higher During the transportation of condensed water with oxygen concentration, it is easy to accumulate water flow and cannot be discharged in time, thus affecting the service life of the pipeline
