Existing dryers are generally divided into thermal adsorption dryers and non-thermal adsorption dryers. In order to continuously supply gas downstream, almost all adsorption dryers are designed with a double-tower structure, with one tower performing adsorption and the other tower simultaneously regenerating the adsorbent.

　　In existing life, compressed air is widely used in industry and civil use, and compressed air purification technology is becoming more and more advanced. However, existing zero air consumption dryers mostly do not have corresponding temperature control structures during use, resulting in the equipment being unable to adapt to load changes of 10%-100%, resulting in poor equipment performance, and affecting the regeneration effect when reducing or stopping air consumption.

　　In order to overcome the shortcomings of the existing technology, technicians provide a temperature control structure for a zero air consumption dryer. In order to solve the above technical problems, the temperature control structure of the zero air consumption dryer adopts the following technical scheme: The temperature control structure of the zero air consumption dryer includes a first adsorption tower and a second adsorption tower. The top of the first adsorption tower is fixedly connected to a pipe 1, and the end of pipe 2 away from the first adsorption tower is fixedly connected to the top of the second adsorption tower. Two valves 1 are fixedly installed on the outside of pipe 1, and two valves 2 are fixedly installed on the outside of pipe 2.

　　The exhaust pipe is fixedly connected to the outer side of pipe 1 between the two valves 1. The temperature controller 1 is fixedly installed on the outer side of the exhaust pipe, and the temperature controller 3 is fixedly installed on the outer side of pipe 2 between the two valves 2. Pipe 3 is fixedly connected to pipe 2 at one end close to pipe 2. A valve 3 is fixedly installed on one side of pipe 3, and a temperature controller 6 is fixedly installed at the end away from pipe 2. Pipe 5 is fixedly connected between valve 3 and temperature controller 6. Valve 8 is fixedly installed on one side of the auxiliary cooler; pipe 6 is fixedly connected to one end of pipe 5 close to pipe 3; a main cooler is fixedly installed on one side of pipe 5, and a separator is fixedly installed on the outer side of pipe 5 on the main cooler side, and a temperature controller 4 is fixedly installed on the outer side of pipe 5 between pipe 4 and valve 5.

　　The end of pipe 5 away from the first adsorption tower is fixedly connected to the bottom of the second adsorption tower. Six valves are fixedly installed on both sides of pipe 7. The end of pipe 6 away from pipe 5 is fixedly connected to the outer side of pipe 8. The temperature controller 5 is fixedly installed between pipe 4 and pipe 8. The end of pipe 8 away from the first adsorption tower is fixedly connected to the bottom of the second adsorption tower. Pressure gauges are provided on the outer sides of the first and second adsorption towers. Standby heating boxes are provided on the outer sides of the first and second adsorption towers.

　　The beneficial effects of the above-mentioned temperature control structure of the zero air consumption dryer are: compact structure, simple operation, and strong practicality; by setting 6 temperature control structures in the zero air consumption compressed heat dryer, the equipment can adapt to 10%-100% load changes during use, and the regeneration effect of the equipment will not be affected when reducing or stopping air consumption.
