Abstract

The invention discloses a single-row flue gas waste heat recovery device which comprises a shell, wherein more than two gas-liquid heat exchangers are arranged in the shell; each of the gas-liquid heat exchangers which are arranged in a row comprises a front baffle plate, a back baffle plate and more than two plates, wherein a water inlet pipe and a water outlet pipe are arranged on the front baffle plate; the plates are arranged between the front baffle plate and the back baffle plate, salient points are arranged on the plates, two plates form a group, the salient points on each group of theplates are arranged oppositely, two plates of each group of the plates form a water channel; the water channel communicates to the water inlet pipe and the water outlet pipe; the salient points of adjacent two groups of the plates are in contact; a smoke channel is formed between adjacent two groups of the plates; the water inlet pipe is connected to a water inlet header pipe; and the water outletpipe is connected to a water outlet header pipe. The single-row flue gas waste heat recovery device disclosed by the invention is conveniently mounted on a flue of a boiler or other combustion equipment, has smaller influence on the flowing property of flue gas, does not affect exhausting, is high in recovery rate of waste heat in the flue, and has a remarkable energy-saving effect.

Description

technical field [0001] The invention relates to the field of heat recovery devices, in particular to a single-row flue gas waste heat recovery device. Background technique [0002] In the past ten years, due to the shortage of energy sources, with the further development of energy conservation work. A variety of new, energy-saving and advanced furnace types are becoming more and more perfect, and the use of high-quality insulation materials such as new refractory fibers has significantly reduced the heat dissipation loss of the furnace. The advanced combustion device is used to strengthen the combustion, reduce the amount of incomplete combustion, and the air-fuel ratio tends to be reasonable. However, the technology of reducing the heat loss of flue gas and recovering the waste heat of flue gas is still not progressing fast. In order to further improve the thermal efficiency of the kiln and achieve the purpose of saving energy and reducing consumption, recycling flue gas ...
