The utility model discloses a device for prolonging the service life of an iron oxide desulfurizing agent contained in a desulfurizing tower. A blowback, replacement and regeneration structure is provided; when the columnar solid desulfurizing agent placed on the tower plate of the desulfurizing tower is hardened to a certain extent and the resistance in the tower is increased to be more than 70KPa, reverse blowing, replacement and regeneration operations are performed so that the columnar solid desulfurizing agent can be loosened; then the liquid water absorbed by the columnar solid desulfurization is evaporated, and dust attached to the surface of the columnar solid desulfurizing agent is reduced; therefore, the resistance in the tower can be reduced from 70 kPa to 5 kPa, the outlet resistance of the compressor is reduced accordingly, the energy consumption is reduced accordingly, the columnar solid desulfurizing agent can be regenerated, the desulfurizing efficiency is recovered, the service life is prolonged, the columnar solid desulfurizing agent does not need to be frequently replaced, and the consumption of manpower and material resources is avoided.
Description
technical field [0001] The invention relates to gas desulfurization, in particular to a device for prolonging the service life of an iron oxide desulfurizer installed in a desulfurization tower. Background technique [0002] An existing refining and chemical flare air desulfurization device 200 such as figure 2 shown. [0003] Refining flare desulfurization device 200 includes a gas cabinet 50 , two desulfurization towers 60A, 60B, a compressor 70 and a cyclone separator 80 . [0004] A refinery torch discharge air inlet pipe 1 is sealingly connected to one side of the upper cylinder body of the gas cabinet 50, and a valve 101 is installed on it. One end of a refinery torch vent air outlet pipe 2 is sealingly connected to the other side of the lower cylinder of the gas cabinet 50 , a valve 201 is installed on it, and the other end is sealingly connected to the inlet of the compressor 70 . One end of a compressor outlet pipeline 8 is sealingly connected with the outlet of ...
