Description

TECHNICAL FIELD

[0002] In chemical industry, pharmacy, food processing and many other industries, the reaction kettle as the core reaction equipment, its internal reaction process highly depends on the accurate temperature control. The reaction kettle temperature control jacket realizes the effective regulation and control to the temperature in the reaction kettle through the circulating heat transfer medium, plays a key role in guaranteeing product quality and improving production efficiency.

[0003] The heat transfer medium as the key carrier for temperature regulation of the temperature control jacket, its purity has a great influence on the temperature control effect and the equipment life, but in actual production, water is used as the heat transfer medium, and it is difficult to avoid the impurities mixing. Once the impurities enter the temperature control jacket with the heat transfer medium, the impurities will gradually accumulate in the jacket and the inner wall of the pipeline, which will significantly reduce the flow area and hinder the smooth flow of the heat transfer medium, and reduce the heat exchange efficiency. In addition, under the driving of the high-speed flowing heat transfer medium, the large particle impurities will produce strong scouring to the inner wall of the jacket and the pipeline, accelerate the equipment wear and tear, and shorten the equipment service life. For example, in chemical production, the wear of the impurities to the jacket may cause the local thinning of the jacket and the leakage risk, not only causing the waste of the heat transfer medium, but also possibly causing safety accidents, affecting the production continuity, and greatly increasing the maintenance cost and downtime.
