Abstract

The invention relates to the field of papermaking mechanical equipment, and provides a papermaking-raw-material biological-enzyme pretreatment device. The papermaking-raw-material biological-enzyme pretreatment device comprises an upper feeding mechanism for putting papermaking raw materials downwards, a lower discharging mechanism for discharging papermaking raw materials after pretreatment, an enzyme-liquid spraying mechanism arranged between the upper feeding mechanism and the lower discharging mechanism and a material carrying face located at the lower portion of the upper feeding mechanism, wherein the lower discharging mechanism is arranged on the material carrying face, and the enzyme-liquid spraying mechanism comprises a plurality of enzyme liquid outlets for spraying enzyme liquidto the papermaking raw materials. According to the papermaking-raw-material biological-enzyme pretreatment device, the papermaking raw materials can be fully mixed with the enzyme liquid, it is guaranteed that the papermaking raw materials and enzyme can be fully reacted, the product can be delivered to a boiling reaction device and subjected to a boiling reaction after a mixing reaction, the whole pulping process continuously runs, and working efficiency is improved. The invention also provides a papermaking pulping system, and the papermaking pulping system comprises the papermaking-raw-material biological-enzyme pretreatment device, and has the same advantages.

Description

technical field [0001] The invention relates to the field of papermaking machinery and equipment, in particular to a biological enzyme pretreatment device for papermaking raw materials and a papermaking pulp system. Background technique [0002] At present, the amount of alkali used in cooking pulp for household paper production using crop straw as raw material is relatively high (wheat straw 13-15%, reed 17-19%, corn straw 11-12%, rice straw 11-12%) , hardness K=9-13, the pulp after oxygen delignification process after washing such pulp is no longer suitable for the production of natural color household paper, the pulp with existing hardness will be fiber after oxygen delignification It is short and has no pull, and its brightness is low. At the same time, there are more residual alkali in the black liquor. If the residual alkali is recovered by alkali, the cost of alkali recovery will be high, and it will be difficult to deal with the polluted white mud. At the same time...
