The invention discloses a hot water boiler blow-off cooling method and system to solve the problem that sewage cooling equipment in the prior art has no waste heat recovery function, and consequently waste heat resources generated by boiler blow-off are wasted. The hot water boiler blow-off cooling method includes the steps that sewage discharged from a sewage discharge outlet of a hot water boiler is conveyed to a blow-off pipeline communicating with the sewage discharge outlet; and the sewage entering the blow-off pipeline is sequentially conveyed to the beginning end, a heat exchange portion and the tail end of the blow-off pipeline, so that heat exchange between the sewage conveyed to the heat exchange portion and cold water in a softened water tank is achieved. The beginning end communicates with the sewage discharge outlet and is laid between the hot water boiler and the softened water tank, the heat exchange portion is laid in the softened water tank, and the tail end extends out of the softened water tank. Waste heat of the sewage in the blow-off pipeline is used for heating cold water in the softened water tank, so that the purposes that the sewage is blown off after being cooled, and waste heat of the sewage is recovered are achieved.
Description
technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a method and system for blowing down a hot water boiler and cooling down its temperature. Background technique [0002] Boiler blowdown refers to the discharge of part of the boiler water with high salt concentration and high water slag concentration during the operation of the boiler. [0003] At present, the traditional method of boiler blowdown is: use blowdown cooling pool or blowdown cooling tank to reduce the sewage to first cool down the sewage, and then remove the harmful components in the sewage, so that the sewage meets the discharge standard and is directly discharged into the external environment. [0004] Sewage cooling tanks or tanks are used to cool sewage. The cooling pools or cooling tanks require a large investment and occupy a large space. Waste heat recovery measures have not been taken, resulting in a great waste of waste he...
