Description
Technical field
The utility model relates to waste disposal plant, relates in particular to the refining plant of handling papermaking wastewater.
Background technology
The sewage that is produced in the paper-making process mainly comprises wastewater from paper machine and black liquor of pulp making.Along with the increasing of national environmental protection dynamics, the purifying treatment problem of papermaking wastewater has become the principal element of restriction paper-making industry development.Particularly black liquor of pulp making is the prerequisite of the numerous middle small paper mill existence of decision because its composition is quite complicated, intractability is big, day-to-day operation expense height.
Paper industry adopts imido method or alkaline process more, all needs to add a large amount of chemicalses in paper making raw material, and carries out mixedly entering steamer " boiling " with water, pushing after overcuring again, extracts the paper grade (stock) fiber.In whole pulping process, produce a large amount of black liquors, calculate to produce 100 tons of paper pulp daily, the fiber extruding black liquor that produced in one day has about 450～600 tons of 150～200 tons, rinsing paper pulp sewage approximately, one day 600～800 tons of dense black waste water of slurrying that have approximately of the two addition need discharge near the waters factory, and environment, river, farmland are formed huge harm.At present, the black liquor of pulp making treatment measures are had methods such as medicine neutralization, oxygen consumption, anaerobism, thereby because quite complicated causing of the composition in the black liquor of pulp making strengthens the intractability of black liquor, daily transport expense is with high.The centering small paper mill is handled as stated above for a long time and is difficult to for continuing, so the qualified discharge incident is not of common occurrence, it is common all in news media to arrange, omit in printing phenomenon steathily.Do not have for a long time a kind ofly more thoroughly to handle, and method that can " reuse " sewage.
The utility model content
Technical problem to be solved in the utility model provides a kind of papermaking wastewater that purifies also can recycle the wherein refining plant of most of moisture content.
The technical scheme that its technical problem that solves the utility model adopts is: purification of paper-making effluent device of the present utility model, include at least one clean unit, described clean unit include have the effluent stream inlet, the housing of sewage outfall, cooling-water flowing inlet, cooling-water flowing outlet, it is characterized in that: be provided with at least one slabbing crack film in the described housing; Side at the crack film has the sewage routeway of crossing for effluent stream, and this sewage routeway communicates with effluent stream inlet, sewage outfall; And then having the cooling-water duct that cooling water flows through at the opposite side of crack film, this cooling-water duct communicates with cooling-water flowing inlet, cooling-water flowing outlet.
The utility model utilizes crack film treatment and purification papermaking wastewater.Crack film in the clean unit is a kind of high strength, acid and alkali-resistance, high temperature resistant, low temperature resistant high molecular hydrophobic material, has special cracking gap, the diameter (more than the 0.1mm) of the minimum water droplet of its clearance distance (0.2～0.4 μ) little what far away.Can utilize the exhaust steam of steamer discharging in papermaking or the slurrying production that papermaking wastewater is heated, when 70～80 ℃ papermaking wastewater is flowed through crack film one side by sewage routeway, the water purification temperature of its relative film opposite side cooling-water duct will exceed about 50 ℃, produced the temperature difference between papermaking wastewater and the cooling water purification, " saturated vapo(u)r pressure reduction " (middle alternating floor crack film) just arranged, because " the steam " (molecular diameter 10 in the singularity papermaking wastewater of crack film
-7Mm) penetrate a side that enters cooling-water duct behind the film of crack; Meet and be condensed into water immediately after cold, can not turn back to sewage routeway one side again and go.So the refrigerative water purification slowly increases as time goes by, the papermaking wastewater of high temperature side slowly reduces as time goes by and concentrate, thereby reach sewage purification and recycle the purpose of water resources.
Can include several purifying treatment unit in the utility model purification of paper-making effluent treatment unit, can connect by pipeline between each purifying treatment unit, be that the unitary sewage outfall of upper level purifying treatment is connected with the unitary effluent stream inlet of next stage purifying treatment, also can and be unified into one group, form matrix by the pipeline series connection between each group with a plurality of purifying treatment unit.Also can cool-heat-exchanger be set at the not end of refining plant, Duan water coolant does not return input terminus and recycles after cooling, and spissated sewage returns the input terminus circulation and carries out purifying treatment after heating.Papermaking wastewater and cooling water purification reach by cool-heat-exchanger respectively keeps papermaking wastewater and the working temperature of cooling water purification in clean unit, make the workplace that the cooling water purification that more and more increases is got back to be needed, 85～90% the moisture content recycling that is purified in the sewage, papermaking wastewater then fewer and feweri more and more " dense " takes physics, chemistry or biological method to handle qualified discharge thereafter again.Owing to need the final surplus sewage quantity of handling greatly to reduce, only account for 10～15% of raw waste water total amount, also recyclable through spissated lignin alkali in subsequent processes, be used for the additive of high grade paint, therefore can reduce sewage disposal working cost and final quantity discharged significantly.
The beneficial effects of the utility model are, simple in structure, papermaking wastewater can be effectively purified and wherein most moisture content can be recycled, and running cost is low, especially can handle black liquor of pulp making more up hill and dale, help solving the serious sewage of the paper-making industry emission problem that exceeds standard, will produce deep effect China's paper industry.
