The invention provides a RH-DS furnace convenient for deep sulfur removal vacuum treatment and belongs to the technical field of molten steel secondary refining. The furnace comprises an oxygen lance, a vacuum pump system, a vacuum chamber main body, a charging chute, a dip pipe, a steel ladle and a steel ladle bottom blowing argon permeable brick, wherein a top blowing oxygen lance is arranged on the top of the vacuum chamber main body; the upper part of the vacuum chamber is connected with the vacuum pump system; the charging chute is arranged on one side of the vacuum chamber main body; the lower part of the vacuum chamber is connected with the dip pipe by a flange; the dip pipe is inserted in the molten steel in the lower part of the steel ladle in the process of vacuum treatment; and the blowing argon permeable brick is arranged on the eccentric position of the steel ladle bottom. The furnace of the invention has the advantages that the temperature in the vacuum chamber can be ensured, the temperature of the hearth and the dip pipe reaches to 1100 DEG C so as to decrease the slag dross, and even if the slag dross forms, a top gun can melt the slag dross in order to prevent the slag dross from gathering.
