These drawings are simplified schematic diagrams only to illustrate the basic structure of the utility model in a schematic way, so they only show the configurations related to the utility model.
如图1所示，一种热泵喷雾干燥机1，包括喷雾干燥机1，喷雾干燥机1具有进风管和出风管，进风管上设置有电加热器6，出风管上设置有循环风机9。As shown in Figure 1, a heat pump spray dryer 1 includes a spray dryer 1, the spray dryer 1 has an air inlet pipe and an air outlet pipe, an electric heater 6 is arranged on the air inlet pipe, and an electric heater 6 is arranged on the air outlet pipe Circulation fan 9.
还包括热泵，热泵包括箱体，箱体内设置有蒸发器2、压缩机3、冷凝器4以及节流阀5，蒸发器2出口与冷凝器4进口之间连接气态管路，在该气态管路上设置有压缩机3，冷凝器4出口与蒸发器2进口之间连接液态管路，在该液态管路上设置有节流阀5，气态管路、液态管路、蒸发器2以及冷凝器4之间形成循环管路，在该循环管路中设置有冷媒；箱体上开设有气体进口和气体出口，蒸发器2设置在箱体气体进口处，冷凝器4设置在箱体气体出口处；喷雾干燥机1出风管与热泵箱体气体进口连接，喷雾干燥机1进风管与热泵箱体气体出口连接。蒸发器2下方设置有冷凝水收集盒。It also includes a heat pump. The heat pump includes a box body. An evaporator 2, a compressor 3, a condenser 4 and a throttle valve 5 are arranged in the box body. A gaseous pipeline is connected between the outlet of the evaporator 2 and the inlet of the condenser 4. In the gaseous pipeline A compressor 3 is installed on the road, and a liquid pipeline is connected between the outlet of the condenser 4 and the inlet of the evaporator 2, and a throttle valve 5 is arranged on the liquid pipeline, and the gas pipeline, the liquid pipeline, the evaporator 2 and the condenser 4 A circulation pipeline is formed between them, and a refrigerant is arranged in the circulation pipeline; a gas inlet and a gas outlet are provided on the box, the evaporator 2 is arranged at the gas inlet of the box, and the condenser 4 is arranged at the gas outlet of the box; The air outlet pipe of the spray dryer 1 is connected to the gas inlet of the heat pump box, and the air inlet pipe of the spray dryer 1 is connected to the gas outlet of the heat pump box. A condensed water collection box is arranged below the evaporator 2 .
循环风机9上游的出风管上设置有旋风除尘器7和脉冲式布袋除尘器8。A cyclone dust collector 7 and a pulse bag filter 8 are arranged on the air outlet pipe upstream of the circulating fan 9 .
作业时，喷雾干燥机1从 出气管排出湿热气体，通过循环风机9将湿热气体引入热泵箱体，湿热气体先作用在蒸发器2上，蒸发器2去除湿热空气中的水份并吸收热能，水落入下方集水盒中，使其进去热泵箱体之后变为干冷空气，通过热泵中冷媒的作用，将蒸发器2吸收的热能转化给冷凝器4，干冷空气在经过冷凝器4排出箱体的时候受热变为干热空气，干热空气再在电加热器6的加热下进入喷雾干燥机1重新作为喷雾干燥机1的工作热能。During operation, the spray dryer 1 discharges the hot and humid gas from the outlet pipe, and introduces the hot and humid gas into the heat pump box through the circulating fan 9. The hot and humid gas first acts on the evaporator 2, and the evaporator 2 removes the moisture in the hot and humid air and absorbs heat energy. The water falls into the water collecting box below, making it into dry and cold air after entering the heat pump box. Through the action of the refrigerant in the heat pump, the heat energy absorbed by the evaporator 2 is converted to the condenser 4, and the dry and cold air is discharged from the box after passing through the condenser 4. When the body is heated, it becomes dry hot air, and the dry hot air enters the spray dryer 1 under the heating of the electric heater 6 again as the working heat energy of the spray dryer 1.
热泵喷雾干燥机1更节能，有效利用了干燥机排出的这部分湿空气的热能，潮湿空气在风机作用下进入热泵蒸发器2后迅速放热冷凝成水排出来，也就是说水在喷雾干燥机1内吸收了多少热，必然从热泵蒸发器2内被吸收，湿空气中水汽的低位能传给冷媒后再传给循环空气升温。The heat pump spray dryer 1 is more energy-saving, and effectively utilizes the heat energy of the humid air discharged from the dryer. The humid air enters the heat pump evaporator 2 under the action of the fan, and then quickly releases heat and condenses into water to be discharged, that is to say, the water is spray-dried. How much heat is absorbed in the machine 1 must be absorbed from the heat pump evaporator 2, and the low level of water vapor in the humid air can be transferred to the refrigerant and then to the circulating air to raise the temperature.
而除湿热泵因是封闭系统，相当于个保温箱，且不需要对外界进行热交换，仅需输入少部分电能，就可以把系统内的蒸发出的水汽的低位能传给冷媒后再传给循环空气，循环干燥空气再通过加热器进一步升温进入喷雾干燥机1去干燥料液，无尾气排放，减少了尾气处理装置。The dehumidification heat pump is a closed system, which is equivalent to an incubator, and does not need to exchange heat with the outside world. It only needs to input a small amount of electric energy to transfer the low-level energy of the evaporated water vapor in the system to the refrigerant and then to the refrigerant. Circulating air, the circulating dry air is further heated by the heater and enters the spray dryer 1 to dry the material liquid, no exhaust gas emission, and reduces the exhaust gas treatment device.
