Enamel pipe heat exchanger system for waste incineration wet desulphurization exhaust gas

Abstract

The invention discloses an enamel pipe heat exchanger system for waste incineration wet desulphurization exhaust gas. The enamel pipe heat exchanger system comprises an exhaust gas cooler, a wet process scrubbing tower, an exhaust gas reheater and a heating medium water replenishing unit; a first air inlet of the exhaust gas cooler communicates with the outlet of a dust remover; the inlet of the wet process scrubbing tower communicates with the first air outlet of the exhaust gas cooler; the second air inlet of the exhaust gas reheater communicates with the outlet of the wet process scrubbingtower; the heating medium outlet of the heating medium water replenishing unit communicates with the first water inlet of the exhaust gas cooler; the first water outlet of the exhaust gas cooler communicates with the second water inlet of the exhaust gas reheater; the second water outlet of the exhaust gas reheater communicates with the first water inlet; the exhaust gas cooler utilizes exhaust gas at the outlet of the dust remover to heat internal heating medium; the exhaust gas reheater utilizes the heated heating medium to heat the low-temperature exhaust gas at the outlet of the wet process scrubbing tower, so that waste heat of the exhaust gas is fully and efficiently utilized, the steam energy of a factory is saved, and the production cost of an enterprise is reduced.

Description

technical field [0001] The invention relates to the technical field of energy-saving and emission-reduction production, and more specifically relates to an enamel tube heat exchanger system for waste incineration wet desulfurization flue gas. Background technique [0002] With the rapid development of the global economy and the acceleration of urbanization, urban land is becoming more and more tense. The construction and operation of waste incineration plants can effectively alleviate the problem of places for urban domestic waste storage. After incineration, the weight of the garbage is reduced by 80%-85%, and the volume is reduced by 90%-95%. Harmful substances such as bacteria in the garbage are also eliminated after incineration, effectively controlling the secondary pollution caused by domestic garbage; The heat generated can also be used to heat the city or generate electricity, turning waste into treasure. Its environmental value and economic value are high. [0003...
