Abstract
The utility model discloses an electric heating device which comprises a shell composed of a pipe plate at the left side and a shell body. A saddle support seat of a steel horizontal vessel is welded outside the shell body. An energy-saving heat insulation layer is arranged on an outer surface of the shell body. A coil pipe is arranged in the shell body and formed by welding a bent head, a communicating pipe and a plurality of straight pipes penetrating through the pipe plate. A flange is welded on the end portion of each straight pipe, expect for the straight pipes forming two ends of the coil pipe, outside the pipe plate. An electric heating component is arranged on each flange. A heating portion of each electric heating component penetrates into each straight pipe. The straight pipes forming the two ends of the coil pipe are respectively connected with a pipe pass inlet and a pipe pass outlet. According to the electric heating device, double shell pass preheating and pipe pass heating are adopted and outer heat insulation is conducted on the shell body, so that heating efficiency of the whole device is improved, and the phenomenon that the pipes of each electric heating component expose due to the fact that a heat-transfer medium cokes and accumulates scales on a surface of the electric heating component caused by the condition that flow velocity of the heat-transfer medium can not reach requirements is avoided. Due to the fact that sets of the electric heating components are connected with the coil pipe through flange bolts, disassembly, overhauling and repair of the electric heating components are convenient.
