Description
Technical field
The utility model relates to paper making raw material treatment facility, and what be specifically related to use in a kind of stalk papermaking thickens tank.
Background technology
At present, in paper industry, the general timber that adopts is as main raw material, but along with the further deterioration of environment, this employing log is just progressively replaced as the technique of raw material, in order to the needs of paper industry can be ensured to the full extent, engender now employing hair grass, cotton stalk, reed, corn stalk, the careless class such as straw is as the technology of pulping raw material, not only for paper industry provides new fiber source, and achieve the utilization of refuse, change the situation that original above-mentioned material can only burn or go back field, achieve the comprehensive utilization of resource, there is splendid Social and economic benef@.
But just current research conditions, mainly contains following several.
1, in document " adopt biotechnology, stalk pulping and paper-making starts straw pulp green technology for making paper new era ", provide a kind of method utilizing stalk pulping and paper-making, as shown in Figure 2, in digestion process, over dry grass per ton produces black liquor 5.5m to concrete technology flow chart
3, the COD content after shove in black liquor is 40000mg/L, is converted to content of organics and is about 220kg.Although propose in document to utilize biotechnology to process black liquor, be not difficult to find, the mode of this employing boiling processes straw, and the black liquor amount caused is large, and is difficult to process.
2, in document " application study of maize straw in pulp and paper industry ", provide a kind of method that corn stalk skin adopts caustic soda-anthraquinone slurrying, its concrete technology flow process as shown in Figure 3, but this method mainly adopts chemical reagent to process stalk, not hard to imagine, the wastewater treatment in later stage is very complicated, and employing Chlorinated Bleaching, poisonous organic chloride can be produced, be difficult to be applied to large-scale production.
Inventor is in the practice that this area is long-term, through a large amount of experiment repeatedly, determine a new technique, save boiling step, grinding and the stages such as bleaching are united two into one, simplifies technique process, achieve fast low temperature to soften simultaneously, the waste water COD produced and colourity reduce greatly, and pollutional load reduces greatly, and waste water can fully recovering.
And in new technology, conveniently at paper industry, particularly can facilitate the pulping of raw material, above-mentioned raw material needs first to carry out pulverization process before manufacture, then by the raw material after pulverizing through cleaning, softening, be incubated, rub, react, grind, shove, pulp washing, thicken, store up the steps such as slurry.
Especially thicken in step, the tank that thickens of employing plays very crucial effect.Although thicken tank applies very wide in other industry, traditional to thicken jar structure more single, is exactly generally to comprise a common tank body, is provided with agitating device in tank body, and what tank body top was provided with various reagent adds entrance.Although there is the uneven problem of mixing in the tank that thickens also having many documents to propose traditional structure, such as, number of patent application is 201210439188.0, name is called the Chinese patent of " a kind of slurry mixing kettle of production of polyester ", disclose a kind of equipment for chemical sizwe mixing, it is provided with agitator in still, and has the anti-settling at the bottom of still to stir fork in agitator lower end.The mixing kettle of this structure also serves the effect thickened, but what the mixing kettle of this structure did not still depart from traditional sense thickens jar structure.Thisly thicken the material of tank for pulpous state, still cannot normally play a role.First, what in its still, agitator adopted is traditional paddle form, if stirred pasty material, is easy to cause lower leaf, mixes very uneven; Secondly, thickening tank discharging opening is the mouth of pipe arranged in bottom, as the material of pulpous state, is very easy to occur blocking.
Therefore, for the straw sizing process of inventor's research and development, necessary design one specifically thickens tank, makes it meet the demand of technique.
