Abstract
Description
Technical Field
[0001] The utility model relates to a concentrating device, in particular to a fast energy-saving double-effect concentrating unit. Background Art
[0002] Concentration equipment is a general term for a series of equipment used to increase the concentration of solutes in a solution. These equipment increase the proportion of solutes by removing solvents and are widely used in the biopharmaceutical industry, dairy food industry and other industries. Existing concentration units are generally composed of heaters, evaporators, condensers, condensate recovery tanks and other components, and use vacuum negative pressure evaporation to increase the concentration of materials.
[0003] In order to improve the processing efficiency of the equipment and thus increase the extraction concentration of the material, the existing concentrator unit will increase the number of heaters and evaporators to meet the above purpose. However, this kind of design structure of simple quantity stacking, because it does not control the various design dimensions of the equipment, leads to great design defects and irrationality in the actual use of the stacking design structure, resulting in the power consumption of the above equipment being not proportional to the actual effect achieved, resulting in low heat transfer efficiency, slow evaporation speed and large steam consumption. Based on the above problems, the present invention was born. Utility Model Content
[0004] The utility model aims to provide a fast energy-saving double-effect concentrator unit, which can effectively increase the evaporation rate and save a large amount of steam, thereby improving the production efficiency of the enterprise, reducing production costs and achieving energy conservation and emission reduction.
[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a fast energy-saving double-effect concentrator unit, comprising: a first-effect heater, a first-effect evaporator, a gas-liquid separator, a second-effect heater, a second-effect evaporator, a condenser, a cooler and a recovery tank, wherein the first-effect heater, the first-effect evaporator, the gas-liquid separator, the second-effect heater, the second-effect evaporator, the condenser, the cooler and the recovery tank are sequentially connected along the transmission direction of the medium, the heating area of the first-effect heater is smaller than the heating area of the second-effect heater, and the evaporation chamber space of the first-effect evaporator is larger than the evaporation chamber space of the second-effect evaporator.
[0006] It is further configured that the ratio of the heating area of the first-effect heater to the heating area of the second-effect heater is 1:1.38-1.45.
[0007] It is further configured as follows: the first-effect heater includes a first-effect heat exchange tube, the second-effect heater includes a second-effect heat exchange tube, and the diameter-to-height ratio of the first-effect heat exchange tube to the second-effect heat exchange tube is 1:50-65.
[0008] It is further configured that the ratio of the heating area of the first-effect heater to the heating area of the second-effect heater is 1:1.38.
[0009] It is further configured as follows: the diameter-to-height ratio of the first-effect heat exchange tube to the second-effect heat exchange tube is 1:50.
[0010] It is further configured as follows: the ratio of the diameter of the evaporation chamber of the first-effect evaporator to the diameter of the evaporation chamber of the second-effect evaporator is 1.1-1.07:1; the ratio of the height of the evaporation chamber of the first-effect evaporator to the height of the evaporation chamber of the second-effect evaporator is 1:1.
[0011] It is further configured as follows: the first-effect heater, the first-effect evaporator, the gas-liquid separator, the second-effect heater and the second-effect evaporator are connected through a conveying pipeline, and the first-effect heater, the first-effect evaporator, the conveying pipeline, the second-effect heater and the second-effect evaporator are all wrapped with an insulation layer.
[0012] It is further configured as follows: the conveying pipeline includes a first-effect connecting section connecting the first-effect heater and the first-effect evaporator and a second-effect connecting section connecting the second-effect heater and the second-effect evaporator, the first-effect evaporator is arranged on a side close to the first-effect heater, and two ends of the first-effect connecting section are respectively connected to the outer side walls of the first-effect heater and the first-effect evaporator and are arranged obliquely; the second-effect evaporator is arranged on a side close to the second-effect heater, and two ends of the second-effect connecting section are respectively connected to the outer side walls of the second-effect heater and the second-effect evaporator and are arranged obliquely.
[0013] In summary, the utility model has the following beneficial effects: 1. Since the first-effect heater is located close to the input end of the medium transmission direction and generates a steam heat source, the calorific value ratio generated by it is higher than that of the second-effect heater. In order to achieve balanced evaporation of the two heaters, the area of the first-effect heater is set to be smaller than that of the second-effect heater. In addition, the first-effect evaporator is located close to the input end of the medium transmission direction, and the evaporation chamber space of the first-effect evaporator is set to be larger than the evaporation chamber space of the second-effect evaporator. In this way, multiple groups of heaters and evaporator structures are used to increase the evaporation rate and save a lot of steam, thereby improving the company's production efficiency and reducing production costs; the evaporation rate of this setting structure is 30% higher than that of traditional equipment, and the steam consumption is 20% lower than that of traditional equipment; 2. The setting of the insulation layer reduces the temperature consumption in transmission and cooperates with the control of the diameter height of the first-effect heat exchange tube and the second-effect heat exchange tube to better achieve balanced evaporation; 3. Through the inclined setting of the first-effect connecting section and the second-effect connecting section structure, the connection assembly space formed between the heater and the evaporator is reduced while ensuring the original transportation path, so that the assembly structure of the heater and the evaporator is tighter and the overall volume of the unit is smaller.
