Description

Technical Field

[0001] The utility model relates to the technical field of fuel heating equipment, in particular to a fuel heating system. Background Technique

[0002] The fuel closed-loop circulation device is used for high-temperature heating and heat preservation circulation of fuel under closed-loop circulation. In special tests, the fuel circulates in a specific pipeline without returning to the fuel tank, and the fuel temperature needs to be maintained within a certain temperature range; under this working condition, the equipment loading the fuel circulation will do work to heat the fuel, so it is necessary to heat the fuel first and then dissipate heat to meet the test conditions within a certain temperature range.

[0003] However, in the prior art, the heating pipe is directly in contact with the fuel for heating, with poor safety performance, and moreover, the fluctuation value of the temperature range is larger. In this regard, further improvement is needed.

[0004] Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop a fuel heating system. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fuel heating system to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A technical solution of a fuel heating system includes a heating heat exchanger and a cooling heat exchanger. One side of the cooling heat exchanger is connected to an oil inlet pipe I, one side of the heating heat exchanger is connected to an oil inlet pipe II, one ends of the oil inlet pipe I and the oil inlet pipe II are connected to a total oil inlet pipe, an oil outlet pipe I is connected to the heating heat exchanger, an oil outlet pipe II is connected to the cooling heat exchanger, and one ends of the oil outlet pipe I and the oil outlet pipe II are connected to a total oil outlet pipe.

[0008] As a preferred technical solution, a pneumatic diaphragm valve is arranged on the oil inlet pipe I, and an explosion-proof temperature sensor is arranged on the total oil outlet pipe.

[0009] As a preferred technical solution, a water inlet and a water outlet are arranged on one side of the cooling heat exchanger, a water inlet pipe is installed in the water inlet, and a water outlet pipe is installed in the water outlet.

[0011] As a preferred technical solution, a bracket is arranged on the bottom surface of the heating heat exchanger.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: In this embodiment, the system adopts a computer closed-loop control method to control the fuel temperature. Compared with the traditional method of directly contacting the heating pipe with the fuel for heating, this mode uses heat conduction to heat the fuel, which is safer. At the same time, it also reduces the generation of carbon deposits caused by direct heating. At the same time, through the acquisition and feedback of sensors and precise computer control, the fluctuation value in the temperature range is smaller. BRIEF DESCRIPTION OF THE DRAWINGS
