Questions about the waiting sleeve
Thread Content
I don’t know what the structure of the waiting sleeve of your catalytic device is? Is main air, boosted air or non-purified air used? What is the air volume and density? How to adjust the air volume by judging the quality of its effect? We use non-purifying air and pressurized air.
Ours is an 80 coaxial type. The sleeve is located at the bottom of the regenerator. There is a circle of fluidizing air (supercharged air) around the protective layer of the plug valve stem. There are six sets of catalyst distributors (fluidized with non-purified air) on the top of the sleeve. The sleeve fluidizing air volume is 3000---3200Nm/h. There is no specific control of the distributor fluidizing air. There is no measurement, the DN50 pipes are all opened a quarter, and are rarely operated during normal production. They are only turned off when the machine is stopped and the sleeve density is 400kg/m3. As for how to adjust the best effect, we have not tried it, but we have stopped the booster several times for other reasons, and it is still fluidized.
Ours is a 140 coaxial type. The structure is the same as that on the second floor. It is a typical structure. The measuring tube at this position is easily damaged because the expansion compensation tube is easy to damage, so we don’t care too much about the specific value.
