Abstract
The invention discloses a scaling-preventing heavy oil heater which comprises a support, flow guide pipes, heating pipes and a control device. The number of the flow guide pipes is at least 2, and the flow guide pipes are communicated through a connecting pipe. The flow guide pipes are fixed to the support, oil inlets are formed in the side faces of the flow guide pipes, and the heating pipes are movably connected in the flow guide pipes. Heating bars are arranged in the middles of the heating pipes, and cast aluminum layers are arranged on the outer sides of the heating bars. The outer sides of the cast aluminum layers are provided with threads, and the outer diameter of the cast aluminum layers is smaller than the inner diameter of the flow guide pipes by 1-2 mm. Junction boxes are arranged above the heating pipes, and the control device is connected with the heating bars through the junction boxes. The scaling-preventing heavy oil heater is reasonable in structure, the outer-thread cast aluminum heating pipes are adopted for increasing the heating area, the flowing direction of heavy oil is guided, the surfaces of the heating pipes are not scaled, the heat conduction efficiency is high, the heating pipes can be demounted at any time, the outer threads are cleaned, replacement is not needed, operation is simple, safety and reliability are achieved, and the service life is long.
