Embodiment Construction
[0008] The present invention will be further described below in conjunction with embodiment.
[0009] exist figure 1 Among them, the dry gas distributor 3 has a circular dry gas outlet 2 on it, and a square inlet 1 for the catalyst dry gas on the bottom. After heat transfer with the catalyst, the drying gas exits the catalyst channel and enters the square inlet 1 of the catalyst drying gas, and enters the drying gas distributor 3. After passing through the gas distributor, the drying gas flow rate slows down and the contact time with the catalyst is prolonged, and the drying temperature is uniform. It will cause the temperature of the catalyst to fluctuate too quickly after drying, the catalyst will be heated evenly, and the yield will be high.
