Abstract
The utility model relates to the technical field of heat exchange and discloses a high-temperature water heater for recovering the exhaust heat of a boiler flue. The water heater comprises an exchanger body with a flue inlet and a flue outlet; wherein, the flue inlet is connected with the flue of the boiler, the exchanger body is internally provided with a water circulating tube, one end of which is the inlet of cold water and the other end of which is the outlet of hot water. As the improvement of the technical proposal, part of the water circulating tube takes the shape of coiled tube in the exchanger body. The utility model leads the high temperature exhaust gas emitted from the flue and the cold water flowing through the water circulating tube to carry out heat exchange, and turns the cold water in the circulating tube into hot water. Consequently, not only the temperature of exhaust gas is discharged to the outside environment, as well as environmental pressure, reduced, but also the exhaust heat in the flue is utilized well, thus reducing the consumption of energy.
Description
Technical field:
The utility model relates to technical field of heat exchange, especially relates to the high-temperature water heater that a kind of boiler flue Waste Heat Recovery is utilized.
Background technology:
Various fire coals, fuel oil, gas fired-boiler in the course of the work, its flue can give off a large amount of high-temperature flue gas, and environment is caused very big influence.On the other hand, these high-temperature flue gas directly are discharged in the external environment, make flue used heat to recycle, and cause the very big wasting of resources again, and this situation is needed badly and improved.
The utility model content:
The purpose of this utility model is to provide at the weak point of prior art existence a kind of high-temperature water heater of recovery boiler flue used heat.
For achieving the above object, the high-temperature water heater of recovery boiler flue used heat of the present utility model includes the interchanger main body of a band flue entrance and flue outlet, wherein, flue entrance links to each other with the flue of boiler, be provided with water-circulating pipe in the interchanger main body, one end of water-circulating pipe is a cold water inlet, and the other end is a hot water outlet.
As improvement of the technical scheme, the part of described water-circulating pipe in the interchanger main body is coil-like.
After adopting technique scheme, the beneficial effects of the utility model are: it makes the cold water of the flue high-temp waste gas of discharging and the water-circulating pipe of flowing through carry out heat exchange, makes the cold water in the water-circulating pipe become hot water.So not only reduce the EGT that is discharged into external environment, alleviated environmental pressure; And flue used heat is well utilized, reduced the consumption of the energy.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See shown in the accompanying drawing 1: the high-temperature water heater of recovery boiler flue used heat of the present utility model has the interchanger main body 10 of a band flue entrance 11 and flue outlet 12,10 employings of interchanger main body are high temperature resistant, acidproof, corrosion-resistant material is made, and its flue entrance 11 links to each other with the flue of boiler 20.Be provided with water-circulating pipe 30 in the interchanger main body 10, an end of water-circulating pipe 30 is a cold water inlet 31, and the other end is a hot water outlet 32.For improving the exchange efficiency of heat, the part of water-circulating pipe 30 in interchanger main body 10 is coil-like.
