Recycling efficient energy-saving steam-water heat exchange station

Abstract

The invention discloses a recycling efficient energy-saving steam-water heat exchange station. The recycling efficient energy-saving steam-water heat exchange station is mainly composed of a steam heat exchanger, a condensate water recycling and storing box, a recycling variable frequency pump, a condensate water heat exchanger, a water filling variable frequency pump, a circulating pump and a control cabinet. The steam heat exchanger and the condensate water heat exchanger are arranged in a parallel-connection manner; and a first-time outlet of the steam heat exchanger is provided with a connecting pipe, and the steam heat exchanger is connected with the condensate water recycling and storing tank; a water conveying pipe is arranged at the bottom of the condensate water recycling and storing tank and is connected with a second-time inlet of the condensate water heat exchanger; a second-time outlet of the condensate water heat exchanger is connected with a condensate water recycling pipe, and the recycling variable frequency pump is arranged on the water conveying pipe, connected with the condensate water heat exchanger, of the condensate water recycling and storing tank; and a first pressure sensor is arranged on the condensate water recycling pipe. The recycling efficient energy-saving steam-water heat exchange station has the beneficial effects that the function of utilizing and recycling steam condensate water waste heat is achieved, and therefore the utilization efficiency of steam heat exchange is improved; and energy saving and emission reduction are achieved, and meanwhile the heating cost is reduced.

Description

technical field [0001] The invention relates to the technical field of heat exchange stations, in particular to a recycling, high-efficiency and energy-saving steam-water heat exchange station. Background technique [0002] At present, the steam condensate in the steam-water heat exchange station is often at 60°C to 80°C. If it is directly discharged, there will be a lot of energy waste. If the waste heat is not used and recovered, there will also be energy waste. How to use it reasonably and Recycling steam condensate will become the key to reducing heating costs in steam-water heat exchange stations. Contents of the invention [0003] The object of the present invention is to provide a recycling high-efficiency energy-saving steam-water heat exchange station. [0004] The technical solution adopted by the present invention to solve its technical problems is: recycling high-efficiency energy-saving steam-water heat exchange station is mainly composed of steam heat exchan...
