One, technical field
The utility model relates to a kind of paper-making pulping device, especially relates to a kind of low energy consumption, free of contamination paper-making pulping cooking device, belongs to pulping technology for paper-making and apparatus field.
Two, background technology
In traditional chemical pulping process, all to use a certain amount of inorganic chemical under high temperature, high pressure, plant fiber material to be carried out chemical action, so that fiber separation is come out.Yet the waste liquid that it produced, waste gas cause serious pollution to environment.For addressing this problem, self-catalysis ethanol pulping technology has appearred, and the digesting technoloy of this technology has low, the free of contamination characteristics of energy consumption.But, temperature, pressure etc. are all higher than traditional handicraft in the ethanol pulping digesting technoloy parameter, particularly used ethanol is at high temperature in this pulping and digesting technology, the saturated vapour pressure height, the loss of volatility ethanol appears easily, and scatter and disappear and be difficult to avoid explosion limit in airborne ethanol vapor concentration, cause safety because of suffering from; The sealing of used pulp washing apparatus is relative with resistance to pressure relatively poor in the tradition pulping process, can not satisfy the requirement of pulp washing in the ethanol pulping process.
Research thinks that the basic ideas of ethanol pulping technology are: fibrous raw material is packed in the digester, pump into ethanol water in the digester in right amount again; Then,, by the heater that is arranged on the liquid circulation line liquid is heated rapidly simultaneously the liquid forced circulation in the digester by circulating pump, improve temperature to 185～200 ℃ in the digester, insulation a period of time is fully dissolved the lignin in the raw material, obtains paper pulp.Then in closed container, with ethanol water paper pulp is carried out the multistage counter current washing, after reaching washing and requiring, with steam the ethanol water in the paper pulp is cemented out again, continue to feed steam ethanol remaining in the paper pulp is carried out stripping, realize the recovery of ethanol.
Three, summary of the invention
In order to realize self-catalysis ethanol pulping technology, the utility model provides a kind of ethanol pulping device, and that this device can not only be realized is pollution-free, the ethanol pulping digesting technoloy of low energy consumption, and, can carry out Hot swapping washing in the digester to slurry, therefore, simplify pulp preparing process.
The utility model is achieved in that by vertical digester and new preparation cleaning solution storage tank, secondary washing liquid storage tank, once washing liquid storage tank, recovery liquid storage tank forms the ethanol pulping device.The top of vertical digester is furnished with the steam inlet pipe; Digester also is furnished with cooking liquor circulating pump and heater outward, the inlet of circulating pump links to each other with filter screen in being located at digester by pipeline and valve, the liquid outlet of circulating pump links to each other with the heated medium import of heater with valve by pipeline, and the heated medium outlet of heater links to each other with top with the pot body bottom of digester respectively with valve by pipeline; Be furnished with liquid feeding pump and positive displacement pump respectively at new preparation cleaning solution storage tank, secondary washing liquid storage tank, once washing liquid storage tank, recovery liquid storage tank, the inlet of each liquid feeding pump links to each other with filter screen in the digester by pipeline respectively, each liquid feeding pump liquid outlet by pipeline respectively with new preparation cleaning solution storage tank, secondary washing liquid storage tank, once washing liquid storage tank, reclaim liquid storage tank and link to each other; The liquid outlet of each positive displacement pump links to each other with top with the pot body bottom of digester respectively by pipeline and valve, and the inlet of each positive displacement pump links to each other with new preparation cleaning solution storage tank, secondary washing liquid storage tank, once washing liquid storage tank, recovery liquid storage tank respectively; Reclaim the discharging tube and the valve that also dispose independent use on the liquid storage tank; New preparation cleaning solution storage tank is furnished with the feed tube and the valve of independent use.
Characteristics of the present utility model are: do not have the discharging of waste gas, waste liquid in the pulping digestion process, can not pollute environment; Energy consumes low; The preceding washing of floating of paper pulp is finished in digester, simplified technical process and equipment.The overall investment cost and the production run cost of pulping equipment are reduced, have good social benefit and economic benefit.
