Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a crude oil heating heat exchanger. Background Art

[0002] Heat exchangers (also called heat exchangers or heat exchange equipment) are devices used to transfer heat from hot fluid to cold fluid to meet specified process requirements. They are an industrial application of convective heat transfer and heat conduction. Heat exchangers can be classified in different ways. According to their operation process, they can be divided into three categories: partition type, mixed type, and heat storage type (or heat recovery type); according to the compactness of their surface, they can be divided into compact type and non-compact type. In crude oil extraction, since crude oil contains asphalt, mineral wax and other substances, these substances will solidify at room temperature or low temperature, which is not conducive to the transportation of crude oil. Therefore, it is necessary to heat the crude oil through a heat exchanger for easy transportation.

[0003] Traditional heat exchangers lack insulation on the surface of the device, so heat is easily lost. When not in use, condensation and frost are prone to cause damage to the device. In addition, it is inconvenient for personnel to clean and maintain the pipes inside the device.

[0004] After searching the existing patent: Crude oil heating heat exchanger (publication number: CN204301565U), the utility model has a reasonable and compact structure and is easy to use. Through the coordinated use of the heat exchanger body, coils, partitions, baffles and heating furnace, the purpose of heating crude oil for easy transportation is achieved. It is safe, reliable and easy to control temperature, which facilitates operation and improves heating efficiency.

[0005] The crude oil heating heat exchanger is not convenient for insulating the surface of the exchanger body and increasing the surface temperature. Heat is easily lost, affecting the crude oil heating effect. When the outside temperature is low, frost and condensation are easy to form on the surface of the exchanger body, affecting the service life of the exchanger body. In addition, it is not convenient for personnel to take out the coil inside the exchanger tank for inspection and cleaning.

[0006] Therefore, it is necessary to invent a crude oil heating heat exchanger to solve the above problems. Utility Model Content
