In such scheme, due to carry in described heat exchanger tube be boiler discharge tail gas, for improving the rate of heat exchange of the hot exhaust gas in heat exchanger tube and the cold water in water tank, while not increasing cost, the quantity of described heat exchanger tube can be 10 ~ 40, be divided into the capable m row of n to be evenly located in water tank, wherein n and m is positive integer.
In such scheme, the quantity of described heat exchanger tube is preferably 27, and is divided into 3 row 9 to arrange evenly being located in water tank.
In such scheme, for processing soot dust granule contained in boiler exhaust gas or other polluters further, in described exhaust emissions case, be provided with a filter.
In such scheme, described filter can be screen pack, and the aperture of screen pack in exhaust emissions case is less than the aperture of the screen pack in exhaust collection case.
In such scheme, add for ease of the cold water controlled in water tank or hot water discharge, described water inlet pipe and outlet pipe are equipped with a hand-operated valve.
In such scheme, be improve thermal conductivity factor, and prevent heat exchanger tube from water, causing the getting rusty of heat exchanger tube, corrode because of Long term immersion, described heat exchanger tube preferably has the aluminium matter of anticorrosive coat or ferrous material to make by outer surface.
Compared with prior art, the beneficial effects of the utility model are:
1, in the water tank that delivered inside has the heat exchanger tube of hot exhaust gas to be arranged in built with cold water by the utility model, thus realize the heat exchange of hot exhaust gas and water tank inner cold water, after cold water in water tank is heated to form hot water, can be life provides hot water on the one hand, can be boiler provides thermal source on the other hand, so fully recycle the waste heat of boiler exhaust gas, improve the thermal efficiency of boiler, save the energy;
2, after the filter process of the boiler exhaust gas in heat exchanger tube through being provided with in exhaust collection case and exhaust emissions case, significantly reducing the pollutant such as SO2, flue dust contained in boiler exhaust gas, decreasing the pollution to environment;
What 3, carry in heat exchanger tube of the present utility model is boiler exhaust gas, and quality is light, and the large I according to water tank is arbitrarily installed, and structure is simple, and the outer surface of heat exchanger tube is also coated with anticorrosive coat, not fragile.
