Abstract
The invention discloses a flue gas waste heat recovery heat exchanger which comprises casing, a filter screen and heat exchange pipes. A gas inlet cavity, a heat exchange cavity and a gas collection cavity are arranged in the casing from left to right in sequence. A flue gas pipe is communicated on the left side of the gas inlet cavity. The filter screen is installed between the flue gas pipe and the gas inlet cavity. A left baffle is vertically arranged between the gas inlet cavity and the heat exchange cavity. Round through holes are formed in the left baffle, the horizontal heat exchange pipes are communicated in all the through holes, and a plurality of fins are fixed on the pipe walls of the heat exchange pipes. The right ends of the heat exchange pipes are fixed on a right baffle. The flue gas waste heat recovery heat exchanger injects flue gases into the heat exchange pipes, and accordingly the heat exchange pipes and the fins deliver heat for the heat exchange cavity simultaneously; flue gases and liquid in the heat exchange cavity exchange heat in the gas inlet cavity and the gas collection cavity; the filter screen can filter out impurities in the flue gases and fasten flue gas circulation. In addition, the flue gas waste heat recovery heat exchanger is not prone to scale, good in the heat exchange effect, reliable in work, efficient and energy saving.
