Embodiment

[0016] The high-temperature residual steam and high-temperature condensed water in the pressure steam kettle 1 are respectively passed through the residual steam output pipeline 10 and the high-temperature condensed water pipeline 3 into the pressure gas storage tank for flash evaporation, and the flashed steam is exhausted through the output pipeline 11 into the steam culture pool 13 or another pressure steam kettle 14 for reuse, so as to realize the recovery and utilization of waste heat and waste steam.

[0017] The steam after the flash is discharged into the steam culture tank 13 or another pressure steam kettle 14 and operated by one-way valves 17 and 18.

[0018] The condensed water after heat exchange in the pressure gas storage tank 4 is sent to the boiler feed water pool 7 through the pressure in the pressure gas storage tank, and heat exchange coils are installed in the water feed pool to heat the boiler feed water, and the condensed water after heat exchange is disc...

Abstract

The invention discloses a sulfur dioxide desulfuration technology through utilizing and recycling the afterheat from tubular pile pressure steam maintenance, which includes the steps of conducting the high-temperature residual steam and high-temperature condensation water in a pressure steam boiler into a pressure gas tank for flash evaporation, conducting the flash-evaporated steam into a steaming pool or another pressure steam boiler to recycle the residual steam, preheating the boiler water by the recycled residual steam in the steaming pool and by the high-temperature condensation water through a heat exchange system, and conducting the preheated condensation water into the water-film de-duster of the boiler to recycle the counteraction between the sulfur dioxide in the fumes and condensation water. The technology makes reasonable use of the high-temperature condensation water and the residual steam, adopts flash evaporation technology and reasonable process, realizes high recycling rate, and after recycling the residual steam, carries out de-dusting and desulfurization of the fumes from a coal burning boiler by utilizing the high pH value of the condensation water, thus reducing environmental pollution, simplifying the equipment, lowering the cost and producing significant economic benefits and environmental protection effects.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of waste energy and waste heat and environmental protection engineering, and more specifically relates to a technology for recycling waste heat and waste steam of high-temperature condensed water and reusing sulfur dioxide desulfurization for pipe pile pressure steaming maintenance. Background technique [0002] High-temperature and high-pressure equipment is used in many industries such as the chemical industry and manufacturing industry, but the high-temperature condensed water produced is discharged as waste, which not only wastes a lot of energy, but also causes certain pollution to the environment. There is also recycling of high-temperature condensed water, but the reuse of cooled condensed water, especially to remove sulfur dioxide in flue gas, has not yet seen relevant reports at home and abroad. This technology utilizes the specific water quality of the condensed water in the pipe...
