Problems solved by technology
After the high-temperature flue gas has undergone heat exchange and cooling, the flue gas particles mainly formed by incomplete combustion in the flue gas are easy to adhere to the surface of the heat exchange mechanism, reducing the heat exchange efficiency of the heat exchange mechanism. The operating power of the system is not constant, and the heat content of the output flue gas is not linearly stable. For the existing heat exchange mechanism, the flue gas reaches a thermal equilibrium state with the heat exchange medium soon after the flue gas is cooled by heat exchange, and the flue gas Continuing to circulate in the heat exchange mechanism can only form adhesion pollution to the heat exchange mechanism, and cannot increase the heat of the heat exchange medium

The invention relates to a smoke gas waste heat collecting device. The smoke gas waste heat collecting device comprises a housing, a plurality of heat exchange tubes, a plurality of connecting tubes,a water inlet pipeline, a water outlet pipeline and a heat exchange tube drive mechanism, wherein the housing is horizontally arranged, one end of the housing is provided with a smoke gas inlet, and the other end of the housing is provided with a smoke gas outlet; the tube bodies of the heat exchange tubes are vertically arranged inside the housing; the two ends of each tube body separately extendto the outer part of the housing via through holes; ends of the heat exchange tubes are connected to the heat exchange tube drive mechanism; the heat exchange tube drive mechanism drives the heat exchange tubes to vertically shake repeatedly; heat exchange tubes on the two side parts of the housing are separately connected to the water inlet pipeline and the water outlet pipeline; each heat exchange tube is sequentially connected through the corresponding connecting tube; the smoke gas outlet is connected to a smoke discharge tube; a straight discharge hole is formed in the rear side wall ofthe housing; the straight discharge hole is in butt joint to a straight discharge tube; and the other end of the straight discharge tube is connected to the smoke discharge tube. The heat exchange tube drive mechanism is utilized to drive the heat exchange tubes in the housing to generate vibrations in the housing, so that a heat exchange effect while smoke gas is in contact with the heat exchangetubes is strengthened, and smoke gas particles are promoted to not easily adhere onto the heat exchange tubes.
Description
Technical field [0001] The invention relates to a flue gas waste heat collection device. Background technique [0002] Existing energy-saving technologies usually use flue gas heat recovery devices connected to the flue gas outlet pipes of oil or gas equipment to recover the high heat in the flue gas and avoid energy waste; in practice, the applicant has discharged the gas generator set The flue gas is connected to the heat recovery type lithium bromide unit to provide evaporation heat for the generator in the lithium bromide unit. After the high-temperature flue gas undergoes heat exchange and cooling, the flue gas particles mainly composed of carbon black formed by insufficient combustion in the flue gas are easy to adhere to the surface of the heat exchange mechanism, reducing the heat exchange efficiency of the heat exchange mechanism, and, because of the gas generator set The operating power of the flue gas is not constant, and the heat content of the flue gas output is als...
