Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0022] A multi-stage blower-heat synergistic drying device for a desiccant dryer includes a blower 1, an inlet pipe 2 connected to the inlet of the blower 1, the top of the inlet pipe 2 connected to a cooler, two sets of filters 3 installed on the inlet pipe 2 to filter and purify the passing gas, thereby improving the subsequent use effect, an outlet tee 5 connected to the outlet of the blower 1, a heating conveying pipe 6 connected to the outlet tee 5, a butterfly valve 7 installed on the heating conveying pipe 6, the butterfly valve 7 being a double eccentric butterfly valve, a heating channel 8 connected to the heating conveying pipe 6, and a heater 9 installed inside the heating channel 8 to purify the gas passing through the heating channel 8. Heating is performed by a heat exchange jacket 10 fixedly connected to the outer wall of the heating channel 8. The heat exchange jacket 10 can receive the waste heat generated in the heating channel 8. A circulation pump 11 is also provided on the outer wall of the heating channel 8. A heat exchange tube 12 is sleeved on the outside of the heat exchange jacket 10. A preheating tube 13 is sleeved on the outside of the two sets of filters 3. A flow exchange tube 14 is provided between one end of the heat exchange tube 12 and one end of the preheating tube 13. A return pipe 15 is connected to the other end of the heat exchange tube 12 and the other end of the preheating tube 13. The two sets of return pipes 15 are respectively connected to the liquid inlet and liquid outlet of the circulation pump 11. An air outlet pipe 16 is connected to one side of the top of the heating channel 8.

[0023] Furthermore, a circulating heat exchange medium is filled between the preheating pipe 13 and the heat exchange jacket 10, and the circulating pump 11 is installed on the return pipe 15 to form a forced circulation loop.

[0024] Furthermore, the circulating heat exchange medium is water or heat transfer oil, and the inner wall of the heat exchange jacket 10 is provided with spiral guide fins.

[0025] Furthermore, a thermal resistor 4 is installed on the air intake pipe 2 at the corresponding position of the filter 3, which can monitor the air intake temperature at the filter 3 in real time, making it easier to adjust the temperature thereafter, thereby ensuring that the working temperature of the filter 3 is kept in the range of 30-50℃, which can achieve a better filtration effect.

[0026] The implementation principle of this embodiment is as follows: During operation, since the gas temperature input from the air inlet pipe 2 is low, it will reduce the working temperature of the filter 3 when it passes through the filter 3. Then, the heater 9 will generate more heat when it is working. Part of the heat is used to heat the gas passing through the heating channel 8, and the other part of the heat is conducted to the heat exchange tube 12 through the heat exchange jacket 10, and then conducted to the preheating tube 13 through the internal heat exchange medium and pipeline, thereby increasing the temperature of the filter 3. Through the continuous operation of the circulation pump 11, the working temperature of the filter 3 is kept within a high-efficiency working range, thereby improving the performance of the desiccant dryer.
