Embodiment Construction

[0010] The turbulent heat transfer and high-efficiency heat exchange technology of the present invention controls the flow velocity and flow direction of the flue gas entering the heat exchange area by setting the flue gas distributor in the air inlet pipe, and enhances the uniformity of heat exchange of the equipment; The structure is changed into a wave structure, the fins change the structure of the flow channel, and through the change of the flow channel structure, a large number of small vortices are formed when the flue gas flows in the flow channel, and the vortex forms a scouring effect on the wall surface, changing the structure of the flue gas wall layer, and realizing flue gas turbulence Heat exchange, improve the heat exchange performance of flue gas, reduce the temperature difference between gas and water, strengthen the recovery and utilization of waste heat, reduce the operating cost of the enterprise, and better achieve the goal of energy saving.

Abstract

The invention relates to a turbulent heat transfer efficient heat exchange technology. The turbulent heat transfer efficient heat exchange technology comprises the steps that a smoke distributor is arranged in an air inlet tube to control the flow speed and flow direction of smoke entering a heat exchange area, and the uniformity of equipment heat exchanging is enhanced; and an existing flat platetype fin structure is changed to a wave shape structure, fins are changed into a flow pass structure, through the changing of the flow pass structure, the smoke forms a large amount of small-scale vortex in a flow pass during flowing, the vortex forms scouring action for the wall surface, a smoke wall surface layer structure is changed, smoke turbulent heat exchange is realized, the heat exchangeproperty of the smoke is improved, the temperature difference between gas and water is reduced, waste heat recovery is enhanced, the enterprise operation cost is reduced, and an energy-saving targetis better realized.

Description

technical field [0001] The invention relates to a turbulent heat transfer high-efficiency heat exchange technology, in particular to a flue gas-water heat exchanger for waste heat recovery and utilization. Background technique [0002] In the industrial smelting flue gas treatment system, due to the large amount of flue gas generated by the system and the high flue gas temperature when the flue gas is discharged, a lot of waste heat contained in the flue gas is released into the atmosphere. On the one hand, it causes A large energy waste is caused, and on the other hand, it also causes thermal pollution. Effective use of flue gas waste heat has become another way for various enterprises to achieve energy saving and emission reduction. Among them, using flue gas heat exchange to generate hot water is the most common heat recovery method. Without adding new input, improving heat exchange efficiency, strengthening heat recovery, increasing flue gas temperature, and reducing th...
