Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1, the desulfurization tower comprises a desulfurization tower 1, a heat exchanger 2, a gas-liquid separator 3 and a compressor 4, wherein a flue gas outlet of the desulfurization tower 1 is connected with a heat exchange medium inlet of the heat exchanger 2, a heat exchange medium outlet of the heat exchanger 2 is connected with a gas-liquid inlet of the gas-liquid separator 3, and a gas outlet of the gas-liquid separator 3 is connected with the compressor 4.
The cold medium of the heat exchanger 2 is brine, which comes from the public system. The top of the gas-liquid separator 3 is provided with a 10cm thick wire mesh demister which is assembled and disassembled in a disassembling mode. The bottom of the gas-liquid separator 3 is provided with an automatic drainage electromagnetic valve. The heat exchanger 2 is a horizontal tube type heat exchanger 2.
After the methane with the pressure of 30KPa enters a desulfurizing tower 1 to remove hydrogen sulfide, the temperature of the methane is equivalent to the operation temperature required by a desulfurizing system, the temperature of the methane is about 35 ℃, the methane with higher temperature is firstly cooled by a heat exchanger 2 to separate out water, the temperature is reduced from 35 ℃ to 15 ℃, most of moisture in the gas is condensed, and most of condensed water is discharged from the bottom of the heat exchanger 2; the marsh gas enters the gas-liquid separator 3 after passing through the heat exchanger 2, the residual water mist in the marsh gas is intercepted on a demister in the gas-liquid separator 3, the separator 3 effectively catches liquid drops, and meanwhile impurities carried in the marsh gas are further removed. Clean gas flows out of the gas-liquid separator 3 and enters the compressor 4, 20% of gas pumping quantity of the compressor 4 can be increased by cooling the gas at about 20 ℃, and meanwhile, the high-efficiency and stable operation of post-process equipment is guaranteed after the water content of the gas is greatly reduced.
The utility model discloses investment running cost is low, and the installation is used portably, and degree of automation is high, operation maintenance is convenient, the process units energy consumption is low.
