A stove flue gas waste heat recovery device

Abstract

The invention relates to the field of waste heat recovery, in particular to a waste heat recovery device for stove flue gas. Including: flue, steam tank, water storage tank, water guide pipe, float valve, heat exchange fins, cold water pipe, hot water pipe, steam pipe; the steam tank is cylindrical; the water storage tank is frustum-shaped and made of heat-conducting material Made; the flue is vertically arranged in the water storage tank and the two ends of the flue respectively pass through the water storage tank, the top plate and the bottom plate of the steam box; the water guide pipe is installed on the lower part of the side wall of the water storage tank; the heat exchange fin It is spiral; the steam pipe is arranged on the upper end of the steam box and the water storage tank and communicates with the steam box and the water storage tank respectively; the present invention utilizes the high-temperature flue gas to exchange heat with the water in the steam box and the water in the water storage tank in turn to make the The high-temperature flue gas becomes low-temperature flue gas, which effectively solves the problem of flue gas waste heat recovery.

Description

technical field [0001] The invention relates to the field of waste heat recovery, in particular to a waste heat recovery device for stove flue gas. Background technique [0002] In daily life, the stove is widely used. It uses the heat generated by the burner to heat the wok, and the high-temperature exhaust gas is directly discharged out of the furnace. However, the high-temperature flue gas generated by the burner is not effectively used, but is directly discharged to the Outside the furnace, there is a phenomenon of low thermal efficiency and serious waste of heat energy. The amount of heat energy lost is much greater than the amount used. A large amount of hot water and hot steam are often used in the cooking process. Usually, the water needs to be heated separately to obtain hot water and hot steam. It has become a general consensus to recover and reuse the waste heat of flue gas from stoves. Contents of the invention [0003] Therefore, the present invention is made...
