Embodiment Construction

[0038] In the following, the waste heat recovery condensation water saving device of the present invention will be further explained in detail in conjunction with the accompanying drawings and embodiments.

[0039] Such as Figure 1~4 As shown, the waste heat recovery condensation water-saving device of the present invention is generally used in the energy and environmental protection industry, and is arranged in the flue behind the wet desulfurization device. It includes a refrigerant water inlet 1, a refrigerant water outlet 2, a flushing water interface 3, and a top cover 4 , flow blocking heat exchange tube grid 5, tube grid support beam 6, tube grid support column 7, flushing jellyfish tube 8, water collection drop catcher 9, heat exchange tube 10.

[0040] The heat exchange tube 10 is a U-shaped tube arranged perpendicular to the direction of the flue, its water inlet end communicates with the refrigerant water inlet 1 , and its water outlet end communicates with the ref...

Abstract

The invention belongs to the technical field of waste gas purification, and particularly relates to a waste heat recovery condensation water-saving device used for flue gas which is treated by a wet desulfurization device. According to the waste heat recovery condensation water-saving device provided by the invention, the technical principles of a tubular heat exchanger, a tubular dust collector and a water collection drop catcher are combined together, so that waste heat recovery, condensation water recovery and deep dust removal for the wet saturated flue gas treated by the wet desulfurization device can be realized, the problems of dedusting and demisting the flue gas treated by the wet desulfurization device can be solved, and a great deal of water in the flue gas and part of latent heat of vaporization can be recycled. The waste heat recovery condensation water-saving device is generally applied to the energy source environmental protection industry, has the working position at the downstream part of the flue gas wet desulfurization device (FGD) of a thermal power plant, and can be used for catching fine particle dust and gypsum in the flue gas, so that the clean emission of the flue gas of the thermal power plant can be realized, and the dust removing efficiency and the long-term operation stability of equipment are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of exhaust gas purification, and in particular relates to a waste heat recovery condensing water-saving device used for waste heat recovery, condensed water recovery, and dust and fog removal of flue gas after a wet desulfurization device. Background technique [0002] China's coal-based energy structure has resulted in domestic power sources being dominated by coal-fired thermal power generation. At the end of 2010, my country's installed power generation capacity reached about 950 million kilowatts, of which thermal power installed capacity was 700 million kilowatts, accounting for about 73.68% of the total capacity. [0003] The boiler exhaust gas of coal-fired power plant has high temperature, SO 2 , nitrogen oxides and other pollutants with high concentration and large dust content. In order to solve the problem of boiler flue gas emission pollution, a large number of technical measures have been take...
