The filter screen, the fixed net and the supporting net are all filled with activated carbon. The gas is adsorbed by the filter screen, the fixed net and the supporting net, and the moisture inside the steam can be removed.

[0016] 2. The utility model achieves the effect of ensuring that the moisture inside the steam is completely removed by setting a support pipe, a return pipe and an exhaust pipe. After the moisture is removed from the steam, the steam enters the support pipe through the connecting pipe, and a value is set for the humidity sensor. When the moisture inside the steam exceeds the set value, the humidity sensor can transmit a signal to the controller, and the controller transmits a signal to the fixed valve, and the steam can enter the connecting pipe again through the return pipe to remove moisture. When the moisture inside the steam is lower than the set value, the humidity sensor can transmit a signal to the controller, and the controller transmits a signal to the exhaust valve, and the steam can be discharged through the exhaust pipe.
