When the liquid level is higher than the highest point of the condensed water outlet 4, the flue gas in the condensed water pipeline of the heat exchanger can not enter the water outlet elbow pipe 2 any more, so that the liquid seal of the flue gas in the condensed water pipeline of the heat exchanger is realized, namely, the flue gas is sealed in the box body 1. The liquid level in the box body 1 and the water outlet elbow pipe 2 continuously rises, and finally the condensed water in the box body 1 can be discharged through the water outlet end of the water outlet elbow pipe 2.
