Sample cooler for petrochemical industry

Abstract

The application relates to a sampling cooler for petrochemical industry, which includes a frame, a cooling cylinder rotatably arranged on the frame, and a driving assembly that drives the cooling cylinder to rotate around its own axis. The cooling cylinder is fixed with a first sleeve and a second sleeve The outer wall of the first casing and the inner wall of the second casing form an annular first flow passage, and the second casing and the inner wall of the cooling cylinder form an annular second flow passage, and the first flow passage is fixed The first helical tube is helically arranged along the axis of the cooling cylinder as the centerline, and the second helical tube is fixedly arranged in the second flow channel along the axis of the cooling cylinder as the centerline, wherein the helical directions of the first helical tube and the second helical tube are opposite . The application has the ability to drive the cooling cylinder to rotate through the driving assembly, so as to drive the first spiral tube and the second spiral tube to rotate together, so as to guide and push the viscous sample medium in the first flow channel and the second flow channel, and accelerate the viscous The flow of sample medium reduces clogging of viscous sample medium.

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 ...

AI Technical Summary

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
