The invention discloses a double-layer spiral channel jacket layer. The double-layer spiral channel jacket layer is coated on the outer wall of the cylinder of the reaction device. The double-layer spiral channel jacket layer includes: an inner spiral channel, The gap between the outer wall of the cylinder and the inner wall of the inner spiral channel forms the inner spiral channel, the inner spiral channel includes a first nozzle port and a second nozzle port; and an outer layer spiral channel, the inner layer spiral channel The gap between the outer wall of the 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 includes a third nozzle port and a fourth nozzle port; flow within the spiral channel and the outer spiral channel. The double-layer spiral channel jacket layer of the present invention reduces the temperature difference between the inlet and outlet of the medium, reduces the temperature difference between the medium and the wall surface of the inner cylinder of the jacket, makes the temperature distribution of the inner cylinder wall surface more uniform, and reduces the temperature of the medium and the inner cylinder wall surface The irreversible loss can improve the utilization rate of heat energy.
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...
