Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
Below with the accompanying drawings specific embodiment of the present invention.As shown in Figure 1: a kind of intelligent boiler heat recovery system; Comprise the waste-heat recovery device 2 that links to each other with flue 1; The exhaust gases passes and the heat exchanging chamber passage that are provided with tunable in this waste-heat recovery device 2 and close/open are provided with the heat exchanger tube that is connected with air inlet and gas outlet in the heat exchanging chamber 6, after flue gas gets into heat exchanger tube; Carry out heat exchange with the water body in the heat exchanging chamber 6, the flue gas after temperature reduces is discharged through the gas outlet of preheating retracting device 2; Attemperater 3 is provided with water pipe 10, and it is provided with water pump.
The course of work of the intelligent boiler heat recovery system of the embodiment of the invention is following: after the flue gas of high temperature gets into the heat exchanging chamber 6 of waste-heat recovery device 2 through heat exchanger tube; Carry out heat exchange with the medium (water body) of filling in the heat exchanging chamber 6; Flue gas after temperature reduces is discharged through the gas outlet; And the water body after heating up stores among getting into attemperater 3 through circulation line under the effect of water pump, when needs use hot water, opens outlet pipeline 12 hot water supply is got final product to the place that needs.
After the hot water among the attemperater 3 consumes a period of time; Control system 13 control water pipes 10 replenish cold water in attemperater 3; After liquid level detector 9 detects water tank and has been full of, send signal to control system 13, control system 13 control water pipes 10 stop moisturizing; Because the water temperature in the attemperater 3 descends after mixing, heat exchanger tube can carry out heat exchange under heat exchanging chamber 6 and state that smoke inlet is communicated with, make the water body intensification; And attemperater temperature detector 8 is monitored the water temperature in the attemperater 3 at any time, when water temperature reaches preset value, and 13 control waste-heat recovery devices, 2 actions of control system; The heat exchanging chamber pathway closure; Exhaust gases passes is opened, and the flue gas of high temperature is directly discharged through the gas outlet, to prevent the generation of the too high or situation such as dry combustion method, bombing of water temperature.
Through the water pump on entrance flue gas temperature detector 4, exit gas temperature detector 5, temperature detector 7, attemperater temperature detector 8, liquid level detector 9 and each pipeline of the 13 unified controls of control system; Integrate collaborative work, realize intellectuality, the automation control of whole heat recovery system.
