Description
Technical field
The present invention relates to a kind of eliminating white smoke device that dries for being exclusively used in boiler exhaust gas, belong to boiler exhaust gas treatment technology
Field.
Background technology
Contain substantial amounts of ash content, carbon dioxide, sulfide and other impurities inside boiler exhaust gas；The flue gas discharged by chimney
Hot loss of energy is not only caused, and very big pollution is produced to environment.Therefore solution is focused on for boiler exhaust gas in the prior art
The pollution problem of tail gas, but for being proposed in tail gas containing how hot and humid gas handle few related technical schemes, thus
By the pollution control of tail gas, the boiler exhaust gas run out of from chimney is generally the hot and humid gas of white cigarette, occurs emitting white cigarette phenomenon.
The content of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide it is a kind of simple in construction, it is easy to use can
Lean on, the water vapour content in boiler exhaust gas can be reduced, solve the eliminating white smoke dress that dries that tail gas emits the boiler exhaust gas of white cigarette phenomenon
Put.
The purpose of the present invention is completed by following technical solution, a kind of eliminating white smoke device that dries of boiler exhaust gas,
It includes one with boiler exhaust gas interface and flue end is provided with the flue of offgas outlet, is at least set in described flue
It is equipped with sensible heat in a main absorption tail gas and, to reduce the heat exchanger of tail gas exhaust gas temperature, a master is additionally provided with described flue
Vapor latent heat is absorbed in tail gas further to reduce the condenser of exhaust temperature.
As preferred：Described heat exchanger is heat pipe type phase-change heat-exchanger, and the liquid phase of wherein heat pipe type phase-change heat-exchanger is changed
Hot arc is arranged in the flue before condenser, and the gas phase heat exchanging segment of heat pipe type phase-change heat-exchanger is arranged on the cigarette behind condenser
In road, the heat pipe in the heat pipe type phase-change heat-exchanger uses integral fins heat exchange structure；The condenser is a recirculated water cooling
But the water circulation condenser of tail gas, and it is additionally provided with condensate drain outlet in the water circulation condenser.
The invention belongs to improvements over the prior art, it have it is simple in construction, it is easy to use and reliable, boiler tail can be reduced
Water vapour content in gas, solves the features such as tail gas emits white cigarette phenomenon.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail：Shown in Fig. 1, a kind of boiler exhaust gas of the present invention
Eliminating white smoke of drying device, it includes one and carries boiler exhaust gas interface 1 and the flue 3 of offgas outlet 2 is provided with flue end,
In described flue 3 at least provided with one it is main absorb in tail gas that sensible heat is to reduce the heat exchanger 4 of tail gas exhaust gas temperature, described
Flue 3 in be additionally provided with one and main absorb in tail gas vapor latent heat further to reduce the condenser 5 of exhaust temperature.
Shown in figure, described heat exchanger 4 is heat pipe type phase-change heat-exchanger, and the liquid phase of wherein heat pipe type phase-change heat-exchanger is changed
Hot arc 6 is arranged in the flue 3 before condenser 5, and after the gas phase heat exchanging segment 7 of heat pipe type phase-change heat-exchanger is arranged on condenser 5
In the flue 3 in face, the heat pipe in the heat pipe type phase-change heat-exchanger uses integral fins heat exchange structure；The condenser 5 is
The water circulation condenser of one circulating water tail gas, and condensate drain outlet 8 is additionally provided with the water circulation condenser.
It is characteristic of the invention that：Boiler exhaust gas carries out heat exchange, liquid with the liquid phase heat exchanging segment in heat pipe type phase-change heat-exchanger
Phase heat exchanging segment mainly absorbs the sensible heat in tail gas, and the exhaust gas temperature of tail gas is reduced so that tail gas is as close possible to vapor
Dew-point temperature.
Tail gas after cooling carries out heat exchange with condenser again, and condenser mainly absorbs the vapor latent heat in tail gas, and
Continue to reduce exhaust temperature simultaneously, farthest utilize the condensation heat in tail gas so that the water vapour content in tail gas is all the time
It is the maximum vapor meltage under the exhaust temperature, temperature is lower, and the condensation water quantity of release is bigger, and the vapor in tail gas contains
Amount is fewer, and the energy that condensed water discharges is taken out of by the recirculated water in condenser and is used again, and can reach the maximum profit of energy
Effect.
The low temperature saturation tail gas being lowered exchanges heat with the gas phase section of heat pipe type phase-change heat-exchanger again, raises exhaust temperature,
So that the tail gas that saturation tail gas becomes high mass dryness fraction is discharged into air, so as to realize the discharge for reducing vapor in tail gas, reaches and see not
To the purpose for emitting white cigarette.
The present invention utilizes heat pipe heat exchanging principle, and heat pipe is made using monolithic devices fin, substantially increases the heat transfer system of tail gas
Number；Using the voltage divider principle of vapor in tail gas, flue-gas temperature is first reduced to saturation temperature, and then saturation tail gas changes with condenser
Heat, substantial amounts of condensed water is discharged, realize the total emission volumn for reducing condensed water in tail gas；Heat pipe type phase inversion of the present invention
Hot device heats low temperature saturation tail gas, substantially increases the mass dryness fraction of vapor in tail gas again（The solubility of vapor i.e. in tail gas）,
So that tail gas is not in emit white cigarette phenomenon when being discharged into air.
