Dewing-free smoke heat energy carrying and transferring device

Abstract

The invention discloses a dewing-free smoke heat energy carrying and transferring device, relates to heat energy recycling technology and solves the problem of dewing and corroding of heat exchangers in the prior art. The dewing-free smoke heat energy carrying and transferring device comprises a cooler and a heat energy exchanger, the cooler comprises a shell and a cooling pipe arranged in the shell, one end of the cooling pipe is communicated with an evaporator through a water outgoing pipe, the evaporator is communicated with the other end of the cooling pipe through a water incoming pipe, the heat energy exchanger is communicated with the evaporator through a steam pipe and a condensation pipe respectively, an input pipeline for feeding of a low-temperature medium and an output pipeline for outputting of a high-temperature medium are arranged on the heat energy exchanger, a first thermodetector is arranged on the water incoming pipe and connected with an automatic control system, according to temperature detected by the first thermodetector, the automatic control system can adjust transferring quantity of the low-temperature medium in the input pipeline to control the temperature of liquid sequentially entering the evaporator and the water incoming pipe from the condensation pipe and finally reaching the cooling pipe to be higher than a dewing point of smoke in the cooler.

Description

technical field [0001] The invention relates to heat energy recycling technology, in particular to a heat transfer device for non-condensing flue gas. Background technique [0002] In the modern industrial production process, there is a lot of flue gas emission, such as sintering, cement kiln, glass kiln, coking oven, coal-fired boiler, gas boiler, oil-fired boiler and other processes, and the flue gas emitted contains a lot of heat. It is called flue gas waste heat. The flue gas waste heat resource belongs to secondary energy, which is the product of primary energy or combustible material conversion, or the heat left after the completion of a certain process of the heat emitted during fuel combustion. [0003] Specifically, in addition to a large amount of heat, the exhausted flue gas usually also contains water vapor, sulfur oxides, nitrogen oxides, dust, etc., and the flow rate is relatively large. If the flue gas from industrial kilns and boilers is discharged directly ...
