Further, the discharge pipe line is equipped with drain valve.
Further, the precipitating bottom of chamber portion is ramped shaped, is lowest order positioned at the side of discharge outlet, and communicating valve body is located at heavy
It is connected at the lowest order in shallow lake bottom of chamber portion with desulfurization chamber.
Further, the bore of the material inlet and desulfurization tank body in angle of 45 degrees, are convenient for addition attapulgite, molecular sieve
With the materials such as porcelain ball.
Further, the connection valve body is solenoid valve.
Further, control valve is equipped on the discharge outlet and flowline.
The beneficial effects of the present invention are: a kind of absorption desulphurization plant structure for gasoline naphtha of the invention is simple, make
With conveniently, it is effectively prevent erosion of the water in naphtha to desulfurizing agent, the cycle of operation is long, and the water passed through in naphtha settles row
Out, it avoids desulfurizing agent at mud, hardened, bed is caused to block, the water that the porcelain ball for being seated in pot bottom can prevent reaction from generating is to de-
The erosion of sulphur agent, and then desulfurizing agent argillization is prevented, block bed.
