Brief description of the drawings
Fig. 1 is the structural representation of the efficient flue gas waste heat retracting device described in the application.
Detailed description of the invention
As shown in Figure 1, a kind of efficient flue gas waste heat retracting device, comprise that flue 4 and caloic reclaim chamber 5, reclaim 5 tops, chamber in caloic and be provided with water injector 2, be provided with sprayer unit 1 at flue 4 tops, reclaim 5 bottoms, chamber in caloic and be provided with water tray 3, reclaim 5 tops, chamber in caloic and be also provided with cold flue gas outlet.
Sprayer unit 1 is preferably installed at flue 4 porch.
The exhaust heat recovering method of above-mentioned efficient flue gas waste heat retracting device is, flue gas enters flue 4 by flue entrance, be arranged on the sprayer unit 1 at flue 4 tops to flue gas spray atomizing water, flue gas enters caloic and reclaims chamber 5 subsequently, the water injector 2 that is arranged on caloic recovery 5 tops, chamber is sprayed water to flue gas, cold flue gas after heat exchange is discharged by the cold flue gas outlet that is arranged on caloic recovery 5 tops, chamber, and the water absorbing after waste heat falls into the water tray 3 that is arranged on caloic recovery 5 bottoms, chamber.Hot water in water tray 3 enters heat pump 6 by water pump 7, after heat release, enters sprayer unit 1 and water injector 2 by pipeline, is again ejected, and continues the waste heat of recovered flue gas, completes waterway circulating.
The main purpose of this device is heat and the moisture reclaiming in the flue gas producing after the fuel combustions such as natural gas, in the process of off-gas recovery heat, have two diabatic processes: the first stage is humidification cooling procedure, the second process is that flue gas is cooling and follow steam condensation process.The heat exchange of first stage requires to spray to such an extent that particle water is the smaller the better, and require flue gas will have comparatively strong flow-disturbing, its flow velocity is had relatively high expectations, heat exchange just can reach good effect, and in second stage, if spray to such an extent that particle water is too little, flue gas flow rate is too high, moisture will be blown out with flue gas, and in this flue gas recovery device, the object of recycle-water just can not be reached.
In order to realize the effect of abundant heat exchange, the humidification of first stage cooling procedure are mainly arranged in flue and are completed, sprayer unit 1 sprays the water smoke that particle is little, and for abundant disturbance flue gas, the angle in the spray direction of sprayer unit 1 and flue between the flow direction of flue gas is 90 °～180 °.In the time that this angle is 90 °, spray direction is vertical with the flow direction of flue gas in flue; In the time that this angle is 180 °, spray direction is contrary with the flow direction of flue gas in flue.
Cooling and the steam condensation process of the flue gas of second stage mainly occurs in caloic and reclaims in chamber 5.The particle of the water that water injector 2 sprays is greater than the water fog particle that sprayer unit 1 sprays.And the flow velocity of flue gas is less than the flow velocity of flue gas in flue 4 in caloic recovery chamber 5.
At flue entrance, place installs sprayer unit additional, now flue gas flow rate is high, atomized water and the flue gas disturbance of spray are strong, rapidly by flue gas humidification, and be quickly cooled to saturation state, enter like this flue gas that caloic reclaims chamber reclaim indoor be just easy to by shower water cooling, simultaneously water vapour condensation, volume and space that caloic reclaims chamber to be needed reduce, and reclaim caloic more abundant.
Preferably, sprayer unit 1 is arranged on top or the bottom of flue 4, or is evenly arranged along the internal perisporium of flue 4.
