The invention provides an ABS powder drying method, comprising a step of powder drying and a step of powder recovery. In the step of powder drying the technology of utilization of waste heat of condensed water comprises conveying the steam condensed water in a nitrogen heater to a buffer hot water tank as heating medium hot water in a heater. A slurry recovery tank is connected to a bottom portion of a washing tower. The upper portion diameter of the washing tower is slightly bigger than the bottom portion diameter. No filling material and no tray floor are arranged inside the washing tower. The washing tower is provided with a demister, and second spray water in the upper portion of the washing tower. A split-range controller is arranged on the top portion of the washing tower. A first fire extinguishing device is installed in a fluidized bed dryer. A second fire extinguishing device is installed at the exit port of a cyclone separator. An oxygen detector is installed at a nitrogen inlet side of the nitrogen heater. The method of the invention has the advantages of full utilization of the waste heat, energy saving and consumption reduction, heat utilization efficiency improvement, short process flow, reduction of powder loss, reduction of equipment investment, high operation flexibility and stability in the whole technology process, a good ABS separating effect, and good safety performance.

The invention discloses a PSA oxygen generator comprising a first module adsorption separator, a second module adsorption separator, a module purge separator, an oxygen production pipeline and a sound-absorbing exhaust pipeline, the first module adsorption separator includes a second module One upper vent and the first lower vent; the second module adsorption separator includes the second upper vent and the second lower vent; the module purge separator includes the third upper vent and the third lower vent; oxygen production One end of the pipeline is connected to the third upper vent, the other end is connected to the first lower vent and the second lower vent, and the silencer exhaust pipeline is connected to the first upper vent and the second lower vent. The two upper vents are connected, and both the first exhaust valve and the second exhaust valve are needle valves. The oxygen content of the PSA oxygen generator can be monitored in real time through the first exhaust valve on the oxygen production pipeline, so as to control the oxygen production effect of the PSA. The opening and closing of the second exhaust valve on the silencer exhaust pipeline can control the gas output, so that Debug the instrument to ensure the safety of the instrument.

The invention relates to a novel regenerative scorching device for a fixed bed catalyst and a process thereof, in particular to a device for simultaneously scorching in a fixed bed multi-bed catalyst reactor and a process thereof as well as a device for simultaneously scorching catalysts in multiple fixed bed reactor series connectors and a process thereof. The technical scheme of the invention is that: a device for simultaneously scorching at multiple sections in a catalyst device of a fixed bed reactor comprises a heating furnace, a regenerative recycle gas compressor, a catalyst reactor and a regenerative recycle gas liquid separation tank, wherein a catalyst bed is formed in the reactor; a pipeline which is communicated with an outlet pipeline of the regenerative recycle gas compressor is arranged between the outlet pipeline and the lower section bed inlets of two adjacent beds; and the pipeline is provided with a compressed air replenishing pipeline which is communicated with the pipeline. Due to the adoption of the device and the process, the scorching time of a catalyst can be shortened, gas, industrial electricity and circulating water can be saved, the energy consumption of the device can be lowered, the scorching safety can be ensured, and the production capability of the device can be increased.
