Title:
HEATING AND HEAT PRESERVATION JOINT DEVICE FOR PETROLEUM PIPE
Document Type and Number:
WIPO Patent Application WO/2017/193506
Kind Code:
A1
Abstract:
Provided is a heating and heat preservation joint device for a petroleum pipe, comprising an inner steel pipe (1), an outer steel pipe (2), flange joints (3), a power generating device (4), and a heating device (5). The inner steel pipe (1) is arranged inside the outer steel pipe (2), and a flange joint (3) is arranged on both ends of the inner steel pipe (1) and the outer steel pipe (2). The power generating device (4) comprises a generator (6), an impeller device (7), a rotating shaft (8) for blades, and a transmission (9), the impeller device (7) being mounted on an end of the rotating shaft (8) for the blades in the inner steel pipe (1), the generator (6) being arranged on the outer steel pipe (2) and a rotating shaft of the generator (6) being connected to the outer end of the rotating shaft (8) for the blades via the transmission (9) so as to drive power generation. The heating device (5) is arranged between the inner steel pipe (1) and the outer steel pipe (2), and a voltage output end of the generator (6) is connected to the heating device (5). The two layers of pipes can effectively enhance the strength of a petroleum transmission pipe and prevent petroleum leakage, and are advantageous for heat preservation, and at the same time, the power generating device (4) for generating power dependent on the flow of petroleum and the heating device (5) are arranged on the pipe to heat the petroleum in the pipe safely.
