The invention discloses a double-layered spiral channel jacket layer. The double-layered spiral channel jacket layer wraps the outer wall of the barrel body of a reaction device and comprises an inner-layer spiral channel and an outer-layer spiral channel, wherein the clearance between the outer wall of the barrel body and the inner wall of the inner-layer spiral channel forms the inner-layer spiral channel, and the inner-layer spiral channel comprises a first connection pipe port and a second connection pipe port; the clearance between the outer wall of the inner-layer spiral channel and the inner wall of the outer-layer spiral channel forms the outer-layer spiral channel, and the outer-layer spiral channel comprises a third connection pipe port and a fourth connection pipe port; a heat-conducting medium can flow in the inner-layer spiral channel and the outer-layer spiral channel. By adopting the double-layered spiral channel jacket layer disclosed by the invention, temperature difference between medium inlet and outlet is reduced, and temperature difference between the medium and the wall surface of the inner barrel of the jacket is reduced, so that temperature distribution of the wall surface of the inner wall is relatively uniform, irreversible loss of the medium and the temperature of the wall surface of the inner barrel is reduced, and the utilization rate of heat energy is improved.
Description
technical field [0001] The invention relates to the field of jacket layers, in particular to a double-layer spiral channel jacket layer applied to the enhanced heat transfer process of reaction, mixing, ball milling and other equipment in the pharmaceutical, chemical, food and other fine chemical industries. Background technique [0002] Reactors, stirring ball mills and other reaction equipment are widely used in food, biology, medicine and chemical industries. Because the reaction equipment is often accompanied by exothermic and endothermic reactions, this means that the reaction equipment needs heat transfer devices to control the reaction temperature to ensure the quality of the product. The jacket is a commonly used heat transfer device for this type of equipment. A heating or cooling medium is passed through the jacket to heat or cool the material in the container. Some heat-sensitive materials (such as starch, cellulose and other polysaccharide polymers) require stri...
