Description
Technical Field
The utility model relates to the technical field of condensate water treatment, in particular to a water supply system for recycling condensate water to a deaerator.
Background
The existing condensate flow is that the condensate generated by each device using steam firstly enters the condensate recovery facilities in the device, then is conveyed to the unified condensate recovery tank of the whole plant through the recovery facilities, and the redundant condensate is conveyed to the circulating water plant through the pump for water supplementing. The process has the defects that the condensed water is used as steam condensate water, the temperature is generally about 200 ℃, the energy is high, the energy in the condensed water is wasted when the condensed water is directly conveyed to a circulating water plant, and the circulating water is used as cooling water, so that the temperature cannot be excessively high, and therefore, the condensed water also needs to be cooled by a plurality of circulating waters before entering the circulating water plant, and a large amount of circulating water resources and waste are wasted.
The operating principle of the deaerator is that the deaerator heats desalted water by utilizing steam, the temperature is raised to 100-110 ℃ in the period, oxygen molecules in water are removed by utilizing the characteristic that the dissolution capacity of oxygen in water is reduced along with the temperature rise, and the produced deaerated water supplies water for a steam generating system, so that the aim of preventing the oxygen molecules in water from oxidizing related equipment pipelines is achieved, and the service life of the deaerator is shortened. The disadvantage of this process is that the temperature of the demineralized water is generally about 40 degrees celsius, and a large amount of steam is required to be consumed to heat the demineralized water to 100-110 degrees celsius, and especially in the initial stage of operation, the demineralized water needs to be continuously contacted with the steam in the water heating process to rapidly increase the temperature, so that more steam is consumed.
