The invention belongs to the technical field of papermaking, and particularly relates to a paper pulp grinding machine and a grinding method thereof. Comprising a pulping part and an enzymatic treatment device, the pulping part comprises a coarse grinding part and a fine grinding part which are arranged in series, the enzymatic treatment device pretreats wood chips, the wood chips subjected to enzymatic treatment are inactivated, washed and dehydrated and then sent to the coarse grinding part for pulping, the enzymatic treatment device comprises a reaction tank, and the top of the reaction tank is covered with a top cover. The top cover covers the interior of the reaction tank to form a reaction chamber for enzyme digestion reaction of wood chips and enzyme liquid, the top cover is provided with a mixing part, the mixing part can stir and mix the enzyme liquid and the wood chips in the reaction tank, the top cover is further provided with an immersion part, the immersion part comprises an immersion plate with a flow channel, and the immersion plate is provided with a water inlet and a water outlet. A pushing part connected with the immersion plate is arranged on the top cover, and the pushing part can push the immersion plate to abut against the wood chips in the reaction tank, so that the wood chips are fully immersed by the enzyme liquid; and the enzyme treatment device is arranged, so that the pulping energy consumption can be effectively reduced.

The invention discloses a fixed bed residual oil hydrogenation catalyst full-cycle vulcanization system and a full-cycle vulcanization method thereof. A vulcanizing agent pipeline is connected with a first heating furnace; the first heating furnace is sequentially connected with a demetallization catalyst reactor with a demetallization catalyst and a desulfurized nitrogen and carbon residue catalyst reactor with a desulfurization catalyst, a denitrification catalyst and a carbon residue removal catalyst through pipelines, and the demetallization catalyst reactor and the desulfurized nitrogen and carbon residue catalyst reactor are further connected with a transition reactor; the desulfurization nitrogen and carbon residue catalyst reactor is connected with a cold and hot high-pressure separation system, the cold and hot high-pressure separation system is connected with a stripping tower, the stripping tower is connected with a second heating furnace, the outlet end of the second heating furnace is connected with a fractionating tower, and the fractionating tower is connected with pipelines for conveying naphtha, diesel oil, heavy dirty oil and hydrogenated residual oil through pipelines. The method has the technical characteristics of being capable of reducing the consumption of start-up wax oil, reducing the output of heavy dirty oil in a high-temperature vulcanization stage, reducing the heavy dirty oil treatment load of a whole plant, reducing dirty oil recycling energy consumption and the like.
