Device is added to catalyst in petroleum resin production technology

The utility model discloses a device is added to catalyst in petroleum resin production technology. The device includes catalyst storage device, catalyst preparation cauldron, catalyst stirred tank, charge pump I, flow control valve I, raw materials reation kettle, tee pipe coupling, charge pump II, extrinsic cycle condenser, four -way union, flow control valve II, washes with alkaline cauldron, reboiler, exsolution tower. Catalyst stirred tank lower extreme discharge gate pass through charge pump I, flow control valve I, tee pipe coupling, charge pump II, four -way union, then let in raw materials reation kettle middle part feed inlet by the pipeline branch pipe with the four -way union intercommunication. Among the the device, catalyst stirred tank lower extreme discharge gate and raw materials reation kettle lower extreme intercommunication has effectively reduced the height that the catalyst adds fashionable charge -in pipeline, has eliminated the hysteretic phenomenon of solid matter among the charge -in pipeline, and the catalyst granules input speed is even, greatly reduced the formation of accessory substance in the production process, practice thrift the cost, improved production efficiency.
