The invention discloses a boiler
waste heat utilization device which specifically comprises a base, a
water storage barrel and a top
cove, a heating space is formed in the base, and a
smoke outlet is formed in the top of the heating space; the
water storage barrel is arranged at the top of the base, a heat exchange device is arranged in the
water storage barrel, and the bottom of the heat exchange device is communicated with a matched
cornice at the top of the heating space; the top cover is arranged at the top of the water storage barrel, an adjusting device is arranged in the top cover, and the bottom of the adjusting device communicates with the top of the heat exchange device; the heat exchange device comprises a flow dividing disc, the side face of the flow dividing disc communicates with spiral heat exchange pipes through rotating devices, and the multiple sets of rotating devices and the multiple sets of spiral heat exchange pipes are arranged. The invention relates to the technical field of
waste heat utilization. According to the boiler
waste heat utilization device, heat in
smoke can be used for conducting
auxiliary heating on water, heat waste is avoided, boiler heating can be more uniform, and the heat exchange efficiency can be improved conveniently.
