Abstract

The invention discloses an energy-saving smoke heat recycling device for a vertical smoke pipe. The energy-saving smoke heat recycling device comprises a body, a heat exchanging assembly and a condensate water collecting assembly. The interior of the body is of a cavity structure, a partition plate is arranged in the body, the cavity structure is divided into a heat exchanging space and a condensate water collecting space by the partition plate. The heat exchanging assembly and the condensate water collecting assembly are arranged in the heat exchanging space and the condensate water collecting space respectively. High-temperature smoke enters the heat exchanging space for heat exchanging, and condensate water produced after heat exchanging is collected by the condensate water collecting assembly. The energy-saving smoke heat recycling device is simple in structure and compact in design; the heat exchanging space and the condensate water collecting space are partitioned, the condensate water collecting function is achieved, and the heat exchanging efficiency and safety are improved.

Description

technical field [0001] The invention relates to the field of flue gas heat recovery, in particular to a flue gas heat recovery energy-saving device for vertical smoke pipes. Background technique [0002] Water vapor is an inevitable product of fuel combustion and an important part of boiler flue gas. Its dew point temperature in flue gas is about 60°C. The temperature of conventional boiler flue gas often exceeds 100°C, so the water vapor in it will not condense. [0003] One application of the boiler flue gas heat recovery device is to recover the heat in the flue gas to heat process hot water or domestic hot water. In order to improve the recovery of waste heat, the inlet water temperature is often lower than 50°C, and sometimes even reaches 10°C. Such a low temperature will cause the surface temperature of part or most of the flue gas heat exchange coil to be lower than that of the water vapor in the flue gas. The dew point temperature causes the water vapor in it to co...
