Recovery device for steam condensation water

Abstract

The invention provides a recovery device for steam condensation water, belongs to the field of electromechanical technology, and solves the technical problems of high cost, low recovery heat, poor quality of the recovered steam condensation water and the like in a traditional recovery device for the steam condensation water. The recovery device for the steam condensation water is arranged between steam equipment and a hot water exchanger of a domestic hot water system and comprises a heat-insulating water collection tank and a hot water pump, wherein one end of the heat-insulating water collection tank is communicated with the steam equipment, and the other end of the heat-insulating water collection tank is connected with the hot water pump through a pipeline 1; the other end of the hot water pump is communicated with the hot water exchanger through a pipeline 2; the heat-insulating water collection tank is an open heat-insulating water collection tank; and a U-shaped water collection pipe is arranged between the heat-insulating water collection tank and the steam equipment. The recovery device has the advantages of simple structure, low cost, high recovery efficiency, easy control, high quality of the recovered steam condensation water and the like.

Description

technical field [0001] The invention belongs to the field of electromechanical technology, and relates to a device for recovering steam condensed water, in particular to a device for recovering steam condensed water from civil buildings to domestic hot water systems. Background technique [0002] Units that use steam produce a large amount of steam condensate during daily production and use. How to realize the effective recovery and utilization of steam condensate has always been a research topic for engineers and technicians. The recycling of steam condensed water is energy-saving and water-saving. It is not only a response to the national energy policy, but also reduces the unit energy consumption cost. It is a constantly innovative and perfect engineering technology. [0003] The HVAC equipment and other heat exchangers in hotels, office buildings, office buildings, hospitals and other civil buildings produce a large amount of steam condensate water below 100 ℃. At presen...

AI Technical Summary

Problems solved by technology

Although the steam condensate is recycled to the domestic hot water system, there are still some defects. When the steam condensate with pressure is discharged from the steam trap, a large amount of secondary steam can be flashed; it is stored in the water storage tank. It needs to be transported to the hot water system again, which consumes a certain amount of electric energy and loses some heat; the large water storage tank is too large, occupies a large area, and the project cost is high, so it is difficult for general units to promote; at the same time, due to the relatively high pH value of steam condensate Low, all or most of the steam condensate is used for the user after storage, which affects the comfort to a certain extent
