The invention discloses an anti-pollution thermal washing wax removing device which comprises a central pipe, an eccentric body, a compression spring, an upper plug, a lower plug, a guide pipe, a push rod and a conical end cap. The upper end and the lower end of the central pipe are connected with an upper oil pipe and a lower oil pipe. The eccentric body is disposed on one side of the central pipe. A cavity communicated with the upper end and the lower end of the eccentric body is arranged in the eccentric body. A duct for connecting the central pipe with the cavity is arranged on the pipe wall of the central pipe. The upper plug and the lower plug are disposed at the upper end port and the lower end port of the cavity. The lower plug is provided with a conical hole. The guide pipe is arranged in the cavity, and the upper end of the guide pipe is fixedly connected with the upper plug. The upper end of the push rod is inserted in the guide pipe, and the lower end of the push rod is provided with the conical end cap. Under the action of a pressing ball, the conical end cap seals the conical hole. The anti-pollution thermal washing wax removing device is connected below a wax precipitation point, short-circuit thermal washing wax removing is achieved, thermal washing efficiency is improved, washing fluid amount is reduced, energy consumption is lowered, the washing fluid is saved, and washing fluid pollution to a reservoir is avoided effectively.
