Description

Technical Field

[0001] The utility model belongs to the technical field of high-voltage heaters, and in particular relates to a composite high-voltage fluid heater. Background Art

[0002] High-voltage heaters utilize a portion of the steam turbine's exhaust to heat feedwater. As a heat conversion device, they are primarily used in the regenerative heat systems of large thermal power plants. Their heat transfer performance directly impacts the unit's economic efficiency and safety. Currently, high-voltage heaters have the following commonly recognized drawbacks:

[0003] In the use of traditional high-pressure heaters, since the heating elements inside the heater are distributed in the middle position of the heater and cannot be moved, the air that needs to be heated by the high-pressure heater flows from the inlet to the outlet at the other end. The temperature difference between the inlet and outlet positions will cause different temperature differences at both ends of the entire heater. The outlet position of the pipeline is in contact with the external environment. The heated gas will lose heat when flowing to the outlet position of the pipeline. It is necessary to heat the air inside the heater to a temperature above the original temperature to ensure that the temperature meets the standard when the gas is output. Traditional high-pressure heaters cannot more effectively even out the temperature at different positions inside the heater, which in turn reduces the use effect of the high-pressure heater. Utility Model Content

[0004] The purpose of the utility model is to provide a composite high-voltage fluid heater, aiming to solve the problem in the prior art that the temperature at different positions inside the heater cannot be more effectively uniformed.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A composite high-voltage fluid heater comprises a shell, wherein the top two ends of the shell are connected with an air inlet pipe and an air outlet pipe, and the bottom ends of the air inlet pipe and the air outlet pipe are provided with an annular heating pipe, and the outer sides of the two annular heating pipes are fixedly connected to the two ends of the shell, and a heating seat is also fixedly installed at one end of the shell, and a plurality of vertical heating pipes are fixedly installed at the other end of the heating seat, and a heating ring is rotatably connected to the other end of the heating ring, and a plurality of bent heating pipes are fixedly installed on one side of the heating ring.

[0007] As a preferred embodiment of the present invention, a heating plate is fixedly mounted on the other end of the plurality of bent heating tubes, a rotating ring is fixedly mounted on the other end of the heating plate, and the outer side of the rotating ring is rotatably connected to the other end of the shell.

[0008] As a preferred embodiment of the present invention, a heating column is fixedly installed on the outer side of the annular heating tube, and the outer side of the heating column is fixedly connected to the outer sides of both ends of the shell.

[0009] As a preferred embodiment of the present invention, a driving motor is fixedly mounted on the bottom of one of the heating columns, and a driving gear is fixedly mounted on the output end of the driving motor.

[0010] As a preferred embodiment of the present invention, a driving gear ring is fixedly mounted on the outer side of the rotating ring, and the outer side of the driving gear ring is meshed with the outer side of the driving gear.

[0011] As a preferred embodiment of the present invention, support frames are fixedly installed at both ends of the bottom of the shell.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1) The annular heating tube can effectively perform preliminary processing and heating on the air at the inlet pipe position, and the temperature of the air at the outlet pipe position can be concentratedly raised to the standard temperature, so that the heated gas can be transported at a maintained temperature in the pipeline. The bent heating tube is also rotated inside the shell, so that the air inside the shell is heated and stirred to a certain extent, thereby increasing the heating effect of the overall high-pressure heater.

[0014] 2) The bent heating tube is driven to rotate by the provided heating ring and heating plate, and the provided driving gear acts on the driving gear ring on the rotating ring, so that the bent heating tube is more convenient to rotate inside the shell, thereby accelerating the heating effect of the air inside the high-pressure heater.
