Description

Technical Field

[0001] The utility model relates to the technical field of water jacket furnaces, in particular to a gas-heat pump water jacket furnace. Background Technique

[0002] A water jacket furnace is a device for heating in an oil well to reduce the viscosity of petroleum, prevent the petroleum from solidifying in the furnace, so as to facilitate the processing of crude oil. Through the increased temperature in the furnace, ice blockage of the internal pipeline is prevented, which may cause the pipeline to burst.

[0003] However, the pipeline is immersed in water for a long time, which causes stains on the pipeline. These stains may affect the heating of the pipeline, resulting in uneven heating of the pipeline.

[0004] To solve the above defects, in the prior art, a Chinese patent with the publication number of CN221122527U discloses an immersion combustion type water jacket furnace. Through the cooperation of a motor, a first bevel gear, a screw rod, a second bevel gear, a connecting block, a frame and a cleaning cylinder, the surface of the gas coiled pipe in the water jacket furnace body can be cleaned to avoid the attachment of water scale on the surface of the gas coiled pipe. Through the cooperation of a rotating rod, a circular gear, a third bevel gear, a driving rod, a fourth bevel gear, a first sprocket, a second sprocket and a chain, the movement of the cleaning mechanism can drive the three cleaning cylinders to rotate, so as to improve the cleaning effect of the cleaning cylinder on the gas coiled pipe.

[0005] The above device uses the cleaning cylinder to clean the gas coiled pipe during use. However, in the above device, the cleaning cylinder only cleans the gas coiled pipe, and the water source in the furnace is not recycled, thus increasing the loss, and the pipeline may be blocked by ice. Therefore, in actual use, the pipeline may be blocked by ice and burst. Content of the Utility Model
