Problems solved by technology
The structure of the sewage system is simple, and the investment occupies a small area, but the continuous sewage is a mixture of steam and water, which is prone to water shock
Poor controllability due to the limited blowdown volume of the steam drum
When sewage is discharged, a small amount of steam diffuses, polluting the environment and water quality
In addition, there are problems of loss of waste heat resources and water resources, and low energy utilization efficiency

The invention relates to an evaporative cooling blowdown system and a blowdown method of the evaporative cooling blowdown system. The evaporative cooling blowdown system comprises an evaporative cooling steam pocket, a continuous blowdown flash tank, a soft water tank and a periodic blowdown flash tank. The evaporative cooling steam pocket comprises periodic blowdown sewage output opening and a continuous blowdown sewage output opening. The continuous blowdown flash tank comprises a continuous blowdown sewage input opening, a continuous blowdown flash tank top output opening and a continuous blowdown flash tank bottom output opening. The softened water tank comprises a heat exchanger. The heat exchanger comprises a heat exchanger input opening and a heat exchanger output opening. The periodic blowdown flash tank comprises a periodic blowdown sewage input opening, a periodic blowdown water outlet, a secondary steam output opening and a continuous blowdown discharged water input opening.The evaporative cooling steam pocket is connected with the continuous blowdown flash tank and the periodic blowdown flash tank. The continuous blowdown flash tank bottom output opening is connected with the heat exchanger input opening of the heat exchanger. The heat exchanger output opening is connected with the continuous blowdown discharged water input opening of the periodic blowdown flash tank. The evaporative cooling blowdown system guarantees normal operation of equipment, achieves cyclic utilization for sewage treatment, reduces waste of water resources and can achieve the dual purposes of saving water and saving energy.
Description
technical field [0001] The invention generally relates to the field of waste heat utilization of a sewage system, in particular to a vaporization cooling sewage system and a sewage discharge method. Background technique [0002] There are several pipeline systems in the vaporization cooling system, and the sewage pipeline system is one of them. Due to the small size of the sewage pipeline system, insufficient attention is often paid to it, resulting in inconsistent design, unclear design division of labor, and uncoordinated interface coordination. Although the sewage pipeline system is small, it is an important pipeline system. It not only affects the quality of the sewage of the vaporization cooling system, but also affects the safety of the system engineering. [0003] The blowdown of the vaporization cooling system is divided into continuous blowdown and regular blowdown. Continuous blowdown, also known as surface blowdown, requires continuous discharge of part of the f...
