Abstract
The utility model discloses a boiler waste heat recycling device which comprises a furnace body. A hearth is arranged at the bottom of the furnace body. The boiler waste heat recycling device is further provided with a preheating water tank. A waste heat flue communicated with the hearth penetrates through the middle of the preheating water tank, an air inducing device is arranged at an air outlet, a cold water injection pipe is arranged above the preheating water tank, a hot water discharging pipe is arranged under the preheating water tank, and the hot water discharging pipe is connected with the furnace body. The boiler waste heat recycling device utilizes heat generated by the water heat flue to heat water in the preheating water tank. When the water in the preheating water tank is heated to the certain temperature, a temperature sensing control valve is opened automatically, and the heated water is injected into a boiler. Thus, the waste heat of the waste heat flue can be fully utilized, the fuel is saved, and the operation efficiency of the boiler is improved.
Description
Technical field
The utility model relates to a kind of boiler servicing unit, particularly a kind of boiler used heat re-use device.
Background technology
At present, the scope of application of boiler is quite extensive, but because this product waste gas that combustion fuel produces in use must discharge, so discharge flue is the necessity of boiler, but in discharging waste gas, part used heat is also discharged along with the discharge of waste gas, like this, not only make amount of heat run off, and also can cause environmental pollution because the temperature of combustion gas is higher.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of heat that can produce waste flue gas of boilers to recycle, and saves the boiler used heat re-use device of the energy.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of boiler used heat re-use device, comprise body of heater, described bottom of furnace body is burner hearth, describedly also be provided with a preheating water tank, the waste heat flue of described connection burner hearth wore from the centre of used heat water tank, and at air outlet place, one blower unit was set, and described preheating water tank's top is provided with cold water water injection pipe, preheating water tank's below is provided with hot water adjutage, and described hot water adjutage connects body of heater.
As further improvement of the utility model, described hot water adjutage place is provided with temperature sense control valve.
The beneficial effects of the utility model are: boiler used heat re-use device of the present utility model, its heat that utilizes waste heat flue to produce heats the water in preheating water tank, in the time that the water in preheating water tank is heated to a certain degree, temperature sense control valve is opened automatically, water after heating is injected in boiler, can make full use of like this waste heat of waste heat flue, thereby reach saving fuel, improve boiler operating efficiency.
