Activated carbon is adsorbed to the paraffin in natural gas, condensate.Final natural gas is taken out of by escape pipe 244 and enters humidifier
In 300.
Saturated vapor is confessed by feeding unit 310, reaches logical by control valve 330 along the circulation path shown in Fig. 1
Road 352, into after ball nozzle cap 354, is sprayed by jet hole 356 and is mixed with natural gas.Ball nozzle cap 354 is in spray
During spilling saturated vapor, 360 ° of rotations are kept by rotating shaft of the central shaft of passage 352, saturated vapor is by multiple nozzles
Mouthfuls 356 sprayed along multiple directions, is reached and is sufficiently mixed with natural gas.It is natural that first flow tester 332 is responsible for detection
The feed flow of gas, concentration detector 334 is responsible for the content that detection is mixed with saturated vapor in the natural gas of saturated vapor.
When the flow that first flow tester 332 detects natural gas is varied from, and concentration detector 334 measured value deviate from it is pre-
During first setting value, message handler 336 is handled testing result, then control valve 330 is adjusted, so as to change saturation
The feed flow of water vapour, until the measured value of concentration detector 334 reaches preset value.
When activated carbon stops the absorption work to natural gas, resistive heater 248 opens heating, the second air inlet pipe 246
Start to be passed through saturated vapor.Saturated vapor enters to be contacted in accommodating cavity 238 with activated carbon, and is arranged according to multiple baffles 210
Gas flowing path circulated, paraffin is taken away with condensate from activated carbon surface.Finally, the subsidiary paraffin of saturated vapor with
Condensate is taken out of from blow-down pipe 242.
