Problems solved by technology

The above methods are all at the expense of consuming extra energy, and there are problems such as high energy consumption, high operating costs, and large equipment investment, especially in power plant boilers. The large volume of thermal equipment makes the investment and operating costs of the system for eliminating white smoke from the chimney remain high, which brings greater pressure on the environmental protection work of the enterprise

Abstract

The invention discloses a system and technology for removing white smoke exhausted from boiler and industrial kiln chimneys. The system comprises a heat pump, a desulfurization process water heat exchanger, an air heater, a supplemental water heater, a plurality of water feeding and discharging pipelines and a plurality of smoke ducts, wherein the heat pump is used for generating low-temperature water and absorbing heat from low-temperature heat source desulfurization process water, accordingly, the temperature of smoke exhausted from an outlet of a desulfurization tower is lowered, and the amount of water contained in the smoke exhausted from the outlet of the desulfurization tower is decreased; meanwhile, the heat pump can generate high-temperature water which is used for serving as a heat source of the air heater to heat cold air, and surplus heat can be recovered, used for outside heating in winter and used for heating supplemental water in non-heating seasons; and the dual functions of smoke waste heat recovery and white smoke removing are achieved, and under the condition that operation of a boiler is not influenced, zero-cost operation of the white smoke removal process is achieved.

Description

technical field [0001] The invention belongs to the technical field of flue gas purification, and in particular relates to a system and a process for eliminating white smoke from power plant boilers or chimneys of industrial kilns. Background technique [0002] Wet desulfurization technology has the advantages of high desulfurization efficiency and low operating cost, so it is widely used in flue gas desulfurization of power plant boilers or industrial furnaces to reduce the emission of pollutants SOx in flue gas. Determined by the characteristics of wet desulfurization technology, the flue gas after wet desulfurization contains a large amount of water vapor, and the moisture in the flue gas at the outlet of the desulfurization tower has reached saturation, so when the flue gas is discharged from the chimney into the atmosphere When the ambient temperature is lower than the exhaust gas temperature, and the lower the temperature, the lower the partial pressure of the saturate...
