Gas drying and desulfurizing device

The invention discloses a gas drying desulfurization device, and relates to the technical field of gas desulfurization, the gas drying desulfurization device comprises a U-shaped body, the bottom of the U-shaped body is provided with a liquid outlet, two ends of the top of the U-shaped body are respectively provided with a gas inlet end sealing cover and a gas outlet end sealing cover through threads, the gas inlet end sealing cover is provided with a gas inlet pipe, and the gas outlet end sealing cover is provided with a gas outlet pipe. An exhaust pipe is installed on the exhaust end sealing cover, and a filtering assembly is installed at one end of the interior of the U-shaped body. Cooling and drying are separated through the arrangement of the U-shaped body, gas is naturally cooled at the left end of the U-shaped body and then discharged, then the gas naturally rises and passes through a desulfurizing agent, activated carbon, a molecular sieve and a membrane filter, desulfurization operation can be effec
