table 1 operating conditions of the motor during one period
Example 5

The specific operation process is as follows:
firstly, the electromagnetic valve I20 is opened, after the adsorbent particles in the collecting tank 19 enter the feeding tank A21, the feeding tank A21 is full of about 15kg, the electromagnetic valve I20 is closed, the electromagnetic valve II 22 is controlled to be opened, the adsorbent particles uniformly enter the cylinder 1, are guided by the tip-shaped disperser 12, and are spread on the vibrating screen plate 9. At this time, the feeding tank B is connected in parallel, the operation of the feeding tank A21 is completed, the whole set of switching process is completed, and the pressure stability of the system is ensured.
Then, the flow of the left air passage 5 is adjusted to be 12m by the ball valve I7 3 And/h, adjusting the air inlet flow of the right air passage 6 to 25m by the rightmost ball valve 3 And/h, adjusting the opening of a ball valve II 18 in the exhaust passage 17, detecting the indicating number of a system pressure gauge I26 to be 0.1-0.5Mpa, opening a heating rope 11, wherein the temperature of a temperature sensor I4-1 is 205 ℃, and after the temperature is constant for 30min, the temperature of a temperature sensor II 4-2 is 110 ℃.

Next, from the double set of nozzles i 10-1 in the left inlet channel 5, which is large-bore, the adsorbent particles are air-screened, and fines below 40 mesh are screened and stored in the collection tank 15.
Further, the sieved adsorbent particles continue to advance under the action of the vibrating screen plate 9, and in a heated area, heat is radiated by the arc-shaped reflecting plate 2 to heat the adsorbent particles, and air flows from the right air path 6 and the double groups of fine nozzles II 10-2 are activated. Because the fine nozzle II 10-2 has a small aperture, a high pressure and high flow rate fresh hot air flow is generated, so that moisture in the adsorbent particles is driven out and discharged from the exhaust passage 17.
And finally, rapidly cooling the adsorbent particles to about 45 ℃ by using a single group of large-aperture nozzles of the right gas circuit 6, opening an electromagnetic valve III 23 on the discharge tank C24 in the discharging system, and collecting the adsorbent particles. When the discharge tank C24 is full, the lower electromagnetic valve IV 25 is opened, the electromagnetic valve III 23 is closed, and the discharge tank D repeats the above operation. The operation is to open the upper electromagnetic valve at the upper end of the discharge tank D in the discharging system, collect adsorbent particles, open the lower electromagnetic valve at the lower end of the discharge tank D after the discharge tank D is full, and simultaneously close the upper electromagnetic valve at the upper end of the discharge tank D. Each discharge tank C24, or discharge tank D, collected about 12.75kg of adsorbent particles.
