In some cases, it is often necessary to drain the tank 11, and therefore a drainage device is further provided on the bottom surface of the tank, and the drainage device can thoroughly drain the water in the tank. Because the condensed water, the vapor and the air exist in the box body 11 at the same time for a long time, the inner wall of the box body 11 is easy to generate the conditions of oxidation corrosion and the like, the box body 11 is damaged, the condensed water in the box body can be polluted by products of oxidation reaction, and in order to avoid the phenomenon, an anti-corrosion layer is arranged in the box body 11.

Since the input pipe 2 inputs liquid and gas simultaneously, the communication position of the input pipe 2 and the water collecting tank 1 should be at a position higher than the tank body for the safety and stability of the input process, so as to prevent the tank body 11 from being unstable due to the excessive liquid level oscillation caused by the gas input into the water from the input pipe 2 as much as possible.

Between the valve 31 and the box body 11, a filtering mechanism can be arranged to filter the condensed water for one time and then add the condensed water into the circulating water, so that the condensed water is ensured not to contain impurities.
Referring to fig. 1, in the present embodiment, the communication position between the input pipeline 2 and the box 11 is located between two openings of two water vapor separation filter elements 12 on the top plate of the box 11; the output pipeline 3 is communicated with the lower part of the side surface of the box body 11, the communication position is close to the bottom surface of the box body 11, two valves 31 and an output water pump 32 are further arranged on the output pipeline 3, and the output water pump 32 is positioned between the valve 31a and the valve 31 b.
The condensate recovery device provided by the embodiment further comprises a control device, and the upper limit liquid level switch 13, the lower limit liquid level switch 14, the valve 31 and the output water pump 32 are all electrically connected with the control device.

Since the liquid level in the tank 11 rises, the gas containing liquid droplets and water vapor flows upward inside the tank 11 under pressure after entering the water collection tank 1. When the gas that contains liquid drop and vapor passes through water vapor separation filter core 12, the air passes through water vapor separation filter core 12 and outside water catch tank 1 from the uncovered loss of water vapor separation filter core 12, liquid drop and vapor then adsorbed on water vapor separation filter core 12, after liquid drop and vapor that water vapor separation filter core 12 adsorbed assemble, condense into the water drop, the water drop drips from water vapor separation filter core 12 and gets into the condensate water in the box 11. When the level of the condensed water in the box body 11 is higher than the upper limit liquid level switch 13, the upper limit liquid level switch 13 transmits information to the control device, the control device opens the valve 31 and the output water pump 32, and the output water pump 32 pumps the condensed water out of the box body 11 through the output pipeline 3 and adds the condensed water into the circulating water through the output pipeline 3.
