The preparation technology of described calcium hypochlorite bleaching liquid comprises the following steps：
(1) lime stone and anthracite are pressed 1：0.12 weight proportion, which is added in limekiln, to be calcined, temperature control 800~
1200 DEG C, the lime of generation is interrupted from kiln bottom is discharged, and added water digestion, obtains the calcium hydroxide containing a small amount of free water；
(2), by the particulate calcium hydroxide containing 3~6% free moistures, added through the auger under niter ash silo from the top layer of chlorination tower, liquid
Chlorine enters from chlorination tower bottom, and calcium hypochlorite bleaching liquid finished product is discharged by chlorination tower bottom, and chemical equation is：2Ca(OH)2+
2Cl2→Ca(ClO)2+CaCl2+2H2O 。
The positive beneficial effect of the present invention is as follows：
1st, the present invention eliminates traditional material papering section, in the absence of the dust in melting process due to using Chinese alpine rush for raw material
With flying chip etc., and Chinese alpine rush silicon content is low, only the half of wheat straw, dragon grass fiber length and it is thin, slurry yield is higher than up to 50%
40% or so of wheat straw, these are the necessary conditions of premise for preparing top grade paper.
2nd, the paper pulp drainability prepared by the present invention is good, after being extracted through the series connection of twice Double screw pulp extruder, extraction rate of black liquor
Up to more than 85%, far above the 75~80% of Straw Pulp, black liquor solid content is 8~10%, and black liquid wave hairdressing is 6Be0 left
It is right.
3rd, chemicals usage of the invention is few, and alkali charge is the alkali number forever significantly lower than Straw Pulp, pollutant yield
It is lower than wheat straw by 30~40%, it can substantially reduce production cost and treatment of wastes produced cost.
4th, the present invention can produce high-grade, the extraordinary cultural paper of high added value, hence it is evident that enhancing enterprise competitiveness.
