Get rid of device of impurity in raw oil

The utility model provides a get rid of device of impurity in raw oil, including the jar body (1), top at the jar body (1) is equipped with raw oil inlet port (11), after the lower bottom of the jar body (1) is provided with the edulcoration raw oil discharge gate (12), from the last first porcelain ball filter layer (21) that has set gradually under extremely in the jar body (1), hydrogenation's catalyst layer (22), an antichlor layer (23) for the dechlorination, second porcelain ball filter layer (24), third porcelain ball filter layer (25), fourth porcelain ball filter layer (26), it adjusts jar temperature controller (3) of the body (1) internal temperature to be provided with in the bottom of the jar body (1). Its advantage lies in: raw oil gets into a jar body (1), and hydrogenation was loaded to the front portion of jar body (1) catalyst S, the N impurity in to raw oil carries out further desorption, then gets into and carry out the dechlorination reaction in loading the jar body (1) rear portion that the antichlor packed, make take off S, the N effect improves, the extension of catalyst life has reduced the processing cost, the utility model discloses desorption impurity is effectual, has saved production cost.
