Sampling cooler for petrochemical industry

Abstract

The invention relates to a sampling cooler for petrochemical industry. The sampling cooler comprises a machine frame, a cooling cylinder rotatably arranged on the machine frame and a driving assemblyfor driving the cooling cylinder to rotate around the axis of the cooling cylinder, a first sleeve pipe and a second sleeve pipe are fixed in the cooling cylinder, and an annular first flow channel isformed between the outer wall of the first sleeve pipe and the inner wall of the second sleeve pipe; and an annular second flow channel is formed between the second sleeve pipe and the inner wall ofthe cooling cylinder, a first spiral pipe spirally arranged with the axis of the cooling cylinder as the center line is fixedly arranged in the first flow channel, a second spiral pipe spirally arranged with the axis of the cooling cylinder as the center line is fixedly arranged in the second flow channel, and the rotating direction of the first spiral pipe is opposite to that of the second spiralpipe. The cooling cylinder is driven by the driving assembly to rotate so as to drive the first spiral pipe and the second spiral pipe to rotate together, so that viscous sample media in the first flow channel and the second flow channel are guided and pushed, flowing of the viscous sample media is accelerated, and blockage of the viscous sample media is reduced.

Description

technical field [0001] The application relates to the field of cooler structures, in particular to a sampling cooler for petrochemical industry. Background technique [0002] In chemical production, it is necessary to regularly sample and analyze process materials or production products. Because most of the materials or products in chemical production are high temperature and high pressure, a cooling device is needed to cool down the sample medium. [0003] related art cooling devices, such as Figure 8 As shown, it includes a cylinder 13 with closed upper and lower ends and a coil pipe 2 that is located in the cylinder and has condensed water. The two ends of the cylinder 13 are respectively provided with a feed pipe 11 and a discharge pipe 12. There are a first sleeve 16 and a second sleeve 17, an annular first flow channel 100 is formed between the outer wall of the first sleeve 16 and the inner wall of the second sleeve 17, and the outer wall of the second sleeve 17 and ...

Problems solved by technology

[0005] In order to increase the contact probability between the coiled tubes and the sample medium, the arrangement of the coiled tubes is often arranged relatively densely, that is, the radial gaps between the coiled tubes and the first sleeve and the second sleeve respectively are small, so as to force the sample medium to contact the coiled tubes. Contact heat exchange can improve the cooling effect, but if it is set in this way, it is easy to increase the flow resistance of the sample medium with high viscosity, and even cause the sample medium with high viscosity to block
