Pipeline cooling device for petrochemical plant

Abstract

The invention discloses a pipeline cooling device for a petrochemical plant and belongs to the technical field of cooling equipment. The device comprises supporting legs, a bracket, a petroleum pipe,a first flange and a second flange. The supporting legs are installed on the two sides of the surface of the bottom of the petroleum pipe; the bracket is mounted at one side of the supporting leg; thefirst flange plate is installed at one end of the petroleum pip; the second flange plate is installed at the other end of the petroleum pipe; a cooler is installed on the surface of the top of the bracket; a water pump is installed at one side of the cooler; the input end of the water pump is connected with the output end of the cooler through a guide pipe; and a stainless steel coil is installedin an inner cavity of the petroleum pipe. Through mutual cooperation of the water pump and the cooler, cold water can be conveyed into a stainless steel coil pipe, so that petroleum in the petroleumpipe can be subjected to heat exchange; meanwhile, heat dissipation fins can volatilize heat on the surface of the outer wall of the petroleum pipe,; and the stainless steel coil pipe can be protectedthrough a filter screen plate, so that normal operation of pipeline cooling is facilitated.

Description

technical field [0001] The invention relates to the technical field of cooling equipment, in particular to a pipeline cooling device used in petrochemical plants. Background technique [0002] Petrochemical industry, referred to as petrochemical industry. Generally refers to the chemical industry that uses oil and natural gas as raw materials. The range is wide and the products are many. Crude oil is cracked (cracked), reformed and separated to provide basic raw materials, such as ethylene, propylene, butene, butadiene, benzene, toluene, xylene, naphthalene, etc. Various basic organic raw materials such as methanol, formaldehyde, ethanol, acetaldehyde, acetic acid, isopropanol, acetone, phenol, etc. can be prepared from these basic raw materials. [0003] Most of the pipeline cooling in existing petrochemical plants is naturally cooled or the outer wall surface is covered with cold water pipes, so that the cooling rate of the oil in the pipeline is low, prolonging the pro...

AI Technical Summary

Problems solved by technology

[0003] Most of the pipeline cooling in existing petrochemical plants is naturally cooled or the outer wall surface is covered with cold water pipes, so that the cooling rate of the oil in the pipeline is low, prolonging the production cycle of the product, which is not conducive to the development of the enterprise. At the same time, the existing petrochemical The pipe cooling equipment in the factory does not have a separate protection function, which easily damages the cooling equipment and reduces the cooling effect of the pipe.
