the multistage naphthalene removal device comprises a coarse naphthalene removal device and a fine naphthalene removal device which are connected in series, wherein the coarse naphthalene removal device and the fine naphthalene removal device are used for sequentially filtering coal gas and enabling the filtered coal gas to enter a heating furnace;
and the analysis treatment device comprises an air charging device which is used for respectively charging desorption gas into the crude naphthalene remover and the fine naphthalene remover so as to regenerate the adsorbents in the crude naphthalene remover and the fine naphthalene remover.
2. The system for removing organic sulfur according to claim 1, wherein the desorption treatment device further comprises a sampler, the sampler is respectively disposed at the gas outlet of the crude naphthalene remover and the refined naphthalene remover, and the sampler is configured to detect information on the sulfur content of the gas discharged from the gas outlet, so as to timely start the gas charging device to charge desorption gas into the crude naphthalene remover and/or the refined naphthalene remover when the sulfur content detected by one of the samplers exceeds a predetermined amount.
3. The organosulfur removal system according to claim 2, further comprising a control device electrically connected to the sampler and the aerator, respectively, the control device being configured to receive the sulfur content information, to send a first control signal to stop the supply of gas into the crude and fine naphthalene removers, and to send a second control signal to cause the aerator to desorb gas into the crude and/or fine naphthalene removers when the sulfur content exceeds a preset amount.
4. The organosulfur removal system according to claim 1, wherein the gas charging device comprises a gas inlet pipe and a heater disposed on the gas inlet pipe, the gas inlet pipe is connected to both the crude naphthalene remover and the fine naphthalene remover, and the heater is configured to heat the desorbed gas in the gas inlet pipe to raise the temperature of the desorbed gas entering the crude naphthalene remover and the fine naphthalene remover so as to desorb and remove impurities adsorbed by the adsorbent and regenerate the adsorbent.
5. The organic sulfur removal system according to claim 4, wherein the gas charging device further comprises a bypass pipeline, two ends of the bypass pipeline are respectively connected to a desorption gas inlet and a desorption gas outlet of the heater, the bypass pipeline is provided with a stop valve, and when the stop valve is opened, the desorption gas in the gas inlet pipeline can directly enter the crude naphthalene remover and the fine naphthalene remover through the bypass pipeline so as to cool filler layers containing the adsorbent in the crude naphthalene remover and the fine naphthalene remover.
6. The organic sulfur removal system according to claim 5, further comprising a gas supply line and a gas booster provided on the gas supply line, the crude naphthalene remover having a first gas inlet connected to the gas supply line and a first gas outlet discharging filtered gas;
the fine naphthalene remover is provided with a second gas inlet connected with the first gas outlet of the coarse naphthalene remover and a second gas outlet connected with the heating furnace, and the gas inlet pipelines are respectively connected with the first gas outlet and the second gas outlet.
7. The organic sulfur removal system according to claim 6, wherein the desorption treatment device further comprises an exhaust duct for discharging a regeneration gas generated after the impurities on the adsorbents in the crude naphthalene remover and the fine naphthalene remover are desorbed, and the exhaust duct is connected to the first gas inlet and the second gas inlet, respectively.
8. The organosulfur removal system of claim 1, wherein there are two of the crude naphthalene removers, the two crude naphthalene removers being connected in parallel;
the number of the fine naphthalene removing devices is two, and the two fine naphthalene removing devices are connected in parallel.
