The utility model for achieving the above object, by the following technical solutions: a kind of waste heat recovery heat exchange water tank, comprising that water tank, described water tank are provided with is provided with some heat exchanger tubes in hot-air inlets, hot air outlet, water tank, heat exchanger tube adopts back-shaped pipeline configuration, heat exchanger tube head and the tail are connected with hot-air inlets and hot air outlet respectively, it is characterized in that: described heat exchanger tube inner wall sleeve is equipped with core pipe and forms double-deck heat exchanger tube.
Described core pipe adopts nonmetallic materials to make, described core pipe cylindrical and heat exchanger tube inwall tight fit.
Described core pipe adopts china clay material to make, described core pipe cylindrical and heat exchanger tube inwall tight fit.
Described core pipe diameter is less than heat exchanger tube internal diameter, and core pipe cylindrical and heat exchanger tube inwall form heat conduction space, airspace.
Described core pipe diameter is less than heat exchanger tube internal diameter, is filled with nonmetallic materials and forms pipe lining between core pipe cylindrical and heat exchanger tube inwall.
Described water tank two side ends is provided with several deashing lids, and two adjacent heat exchanger tubes are formed the passage being interconnected by described deashing lid inner wall space.
Beneficial effect: compared with prior art, when the utility model work, hot-air is through double-deck heat exchanger tube, core pipe can be incubated after heating, avoiding hot-air to enter heat exchanger tube meets after cold and becomes immediately condensed water, the core pipe that nonmetallic materials are made can absorb heat and again the heat of storage slowly be discharged simultaneously, carry out heat exchange with waste heat in water in water tank and heat exchanger tube, the temperature of Water in Water Tanks is raise, change into production, the required hot water of living, reach 60-70 DEG C by the water temperature after 800 DEG C of heat exchange.Use the utility model can effectively utilize the heat in boiler waste gas, saved the energy, protected environment.
