After being separated by the first water separator 22, water drops in the compressed gas enter the heat exchanger 54 through the valve 23, the filter 24, the valve 25, the pipeline 80 and the valve 72 to perform cold and heat exchange with the ultralow-temperature compressed gas cooled by the cold dryer.

In order to prevent condensed water from being contained in the low-temperature compressed gas, a plurality of second water separators (the water separator 32, the water separator 35, the water separator 66 and the water separator 69) with the same structure and principle are designed on a pipeline at the rear end of the cold dryer, and the water separator 32, the water separator 35, the water separator 66 and the water separator 69 mainly comprise a bearing 143, a blade 144, a nozzle 145, an air inlet pipe 146, a water collecting tank 147, a cylinder 148, a rotating shaft 149, a baffle 150, an air outlet pipe 151, a bearing 152, a drain valve 153, a water pipe 154 and the like. When compressed gas is sprayed to the blades 144 through the spray nozzles 145 through the air inlet pipe 146, the blades 144 rotate at a high speed around the rotary shaft 149, tiny water drops condensed in the compressed gas are thrown to the inner wall of the cylinder 148 by centrifugal force and fall into the bottom water collecting tank 147, and then discharged through the drain valve 152 and the water pipe 154, and after the compressed gas is rotated at a high speed by the blades 144 to separate the condensed water, the compressed gas is beaten on the baffle 149 at the inner part of the other side of the cylinder 148, namely, at the inlet of the air outlet pipe 151, even if the rest tiny condensed water still adheres to the baffle 149, flows into the water collecting tank 147 along the baffle, and then flows out of the cylinder 148 and enters the air outlet pipe to be conveyed backwards.

And compressed gas with higher temperature at the front end is cooled and then enters the cold dryer, so that the temperature of a leakage point is favorably reached, and the energy consumption of the cold dryer is reduced. The compressed gas heated to normal temperature by the heat exchanger 54 enters the third water separator 41 through the valve 59 and the valve 55, the third water separator 41 mainly comprises an air inlet 36, a filter bowl 37, an air outlet 39, an air inlet and outlet valve bank 40, small holes 42, a baffle 43, an inclined ladder 57, a drain valve 56 and the like, the third baffle 43 is installed obliquely downwards, the inclined ladder 57 is arranged on the third baffle, the inclined ladder 57 is horizontal and vertical downwards, because the density of carbon dioxide is higher than that of water vapor, the compressed gas is blocked by the third baffle 43, under the blocking and influence of the third baffle 43 and the inclined ladder 57, carbon dioxide flows downwards along the third baffle 43 and bypasses the bottom of the third baffle 43 to enter the second water separator 48 through the pipeline 44 and the valve 51, at the moment, even if very little water drops are contained in the compressed gas, the compressed gas flows downwards into the bottom of the third baffle 43, and the very little water drops in the compressed gas upwards enter the filter bowl 37 through the small holes 42, and many small holes are arranged on the upper part of the filter bowl 37, and the bottom of the filter bowl 37 can be used for water separation of the water separator 37.
The operation process of the air inlet and outlet valve group 40 at the upper part of the third water separator 41 is as follows: the air inlet side is opened, the air outlet side is closed, then the air inlet side is closed, and the air outlet side is opened, so that the alternation is performed. When the air inlet (air inlet of the third water separator) 36 of the air inlet and outlet valve set 40 is opened, a small amount of compressed air with lower temperature enters the top of the third water separator 41 through the pipeline 61, the pipeline 34, the pipeline 35, the air inlet 36 and the air inlet and outlet valve set 40 to be mixed with compressed air with larger water content, the water content compressed air is cooled, wherein the water content is condensed at the bottom of the filter bowl 37, the air inlet 36 of the air inlet and outlet valve set 40 is closed at the moment, the air outlet 39 of the air inlet and outlet valve set 40 is opened, and the dry compressed air with the water content removed at the upper part of the filter bowl 37 flows out through the air inlet and outlet valve set 40 and the air outlet 39 and then enters the air separating cylinder 48 through the pipeline 38, the pipeline 45 and the valve 50. Then the air outlet 39 of the air inlet and outlet valve group 40 is closed, the air inlet 36 of the air inlet and outlet valve group 40 is opened, a small amount of compressed air with lower temperature enters the top of the water separator 41 through the pipeline 61, the pipeline 34, the pipeline 35, the air inlet 36 and the air inlet and outlet valve group 40 to be mixed with compressed air with larger water content, and the compressed air with the water content is cooled down to condense the water content, so that the water and the air are circulated continuously. The oxygen-free and dry compressed gas in the final sub-cylinder 48 is transported to the gas utilization point 46 for use through a valve 49 and a pipeline 47.
Because the main component of the natural gas is methane, water and carbon dioxide are mainly produced after combustion, and condensed water produced in the anaerobic compressed gas production and drying process can be recycled. That is, the condensed water generated by the economizer 4 flows into the water pipe 108 through the water collecting tank 123 and the water pipe 124, the condensed water generated in the gas collecting tank 8 also flows into the water pipe 108 through the drain valve 14 at the bottom, and the condensed water generated by the compressor 18, the water separator 22, the filter 24 and the chiller-dryer 28 respectively flows into the water pipe 114 through the water pipe 112 and the water pipe 113 after meeting the water pipe 108 through the drain valve 106 at the bottom, the drain valve 105, the drain valve 104, the drain valve 88 and the water pipe 87.

At the same time, condensed water in the water separator 32, the water separator 35, the water separator 66 and the water separator 69 respectively flows into the water pipe 114 through the water pipe 81 after flowing into the water pipe 77 through the drain valve 34, the drain valve 65, the drain valve 68 and the drain valve 71.
