Inner and outer double-layer chemical liquid flow pipe cooling device

Abstract

The invention discloses an inner and outer double-layer chemical liquid flow pipe cooling device. The inner and outer double-layer chemical liquid flow pipe cooling device comprises a center bearing arm. The cross section of the center bearing beam is in a circular shape. A plurality of through liquid flow pipes are evenly arranged on the outer circle of the center bearing beam and are tightly attached to one another in a non-contact manner, and a circular ring shape is formed. A plurality of outer cooling pipes are arranged on the outer surface of the circular ring formed by the through liquid flow pipes. A plurality of inner cooling pipes are arranged between the center bearing beam and the through liquid flow pipes and are close, and a circular ring shape is formed. Cooling pipelines are arranged on the inner sides and the outer sides of the liquid flow pipes, so that the problem that single-side cooling is probably caused due to the fact that only the periphery is provided with cooling pipes is avoided, and integral synchronous cooling is achieved. A gap cavity is designed between each through liquid flow pipe and the corresponding outer cooling pipe, by means of the arrangement, direct contact between two kinds of pipelines with the too large temperature difference is avoided so that the temperature cannot be sharply reduced, and the stable and slow temperature reducing effect is achieved.

Description

technical field [0001] The invention relates to a chemical production cooling equipment, more specifically, to a gentle cooling device with inner and outer double-layer liquid flow tubes. Background technique [0002] The cooling process in chemical production is very common, and in most cases it is the cooling of the liquid flow. It is also common in the production process of molybdic acid products. How can the temperature of the liquid flow after the reaction be brought down to a suitable temperature smoothly? Interval is a question that practitioners in this industry need to think about. The traditional method is to use contact physical cooling, which is a test for the pipeline for transporting liquid flow. Rapid cooling may cause the deformation of the pipeline due to thermal expansion and contraction due to sudden rise and fall of temperature, resulting in shortened service life of the pipeline . Moreover, traditional cooling devices are generally installed on the per...

Problems solved by technology

The traditional method is to use contact physical cooling, which is a test for the pipeline for transporting liquid flow. Rapid cooling may cause the deformation of the pipeline due to thermal expansion and contraction due to sudden rise and fall of temperature, resulting in shortened service life of the pipeline

Moreover, the traditional cooling device is generally installed on the periphery of the liquid flow pipe, which may cause uneven cooling of the liquid flow due to heating on one side, and the cooling effect is not good.
