Embodiment
[0037] The hot exhaust gas generated by the company's organic waste gas combustion furnace flows into the boiler equipment through the heat-resistant insulation pipe, and the condensed water in the steam pipeline flows into the boiler equipment through the insulation pipe, and the hot exhaust gas and steam condensate in the boiler equipment are heated. After reaching 40-50°C, the boiler equipment heats the condensed water for 10-15 minutes to generate steam at about 120°C, and the generated steam is transported to the factory plate heat exchanger through the thermal insulation steam pipeline, and then sent to the factory for pure water heating as required; Insulation pipes provide heating sources for office area heating in winter, hot water for washing in dormitories and washing vegetables in canteens, etc.

The invention discloses a method for recycling steam condensation water, organic waste gas burning heat and exhausted gas waste heat. The method comprises the following steps that firstly, hot exhaust gas flows into a boiler; secondly, condensation water flows into the boiler; thirdly, condensation water is heated into new steam or hot water with the temperature of 100 DEG C; fourthly, the new steam is conveyed to a city pure water station or a plate heat exchanger in a factory pure water polishing room through a heat-preserving steam pipeline; fifthly, the steam condensation water produced by the plate heat exchanger in the factory pure water polishing room flows into the boiler, and the third step and the fourth step are repeatedly executed; sixthly, the hot water produced in the third step can be used for supplying heat or hot water through a heat-preserving pipeline; seventhly, hot exhaust gas produced in the sixth step flows into the boiler, and the third step and the fourth step are repeatedly executed. The method has the advantages that the sewage processing and cooling cost is reduced, and the company environmental protection work reaching the national standards is facilitated; the hot water can be led to office areas to supply heat in winter, and the central air conditioner heating cost is saved; the hot water can be used for heating bathing water for dormitories, and the steam cost is saved.
Description
technical field [0001] The invention relates to a method for recycling factory steam condensed water, combustion heat of organic waste gas and waste heat of discharged waste gas, and belongs to the technical field of energy saving and environmental protection. Background technique [0002] Steam condensed water is the condensed water produced by steam during pipeline transportation and medium- and high-temperature plate replacement. It produces about 50T per day and the temperature is about 40-50°C. It is discharged as sewage, causing water vapor to diffuse and sewage treatment costs. , affect the company's environment, and the condensate needs to be cooled before it is discharged, which also incurs a certain cost. In the organic exhaust system, the burner generates a large amount of heat and heat energy during the combustion of organic waste gas, and the temperature of the exhaust gas discharged from the chimney reaches 60°C. The direct discharge of steam condensate water ...
