Abstract
A process for reclaiming the paper-making sludge includes such steps as directly pumping the sludge from sewage treating pool into depositing pool, depositing, filling clean water to become usable pulp, pumping it into intensity pool, regulating its concentration, mixing it with normal pulp, and making paper.
Description
Technical field:
The present invention relates to the paper-making waste mud processing method, be meant the reuse technology field of mud especially.
Background technology:
At present, a large amount of waste sludges landfill nowhere can be caused in the area that some paper mill is concentrated, and also need spend manpower, tool car carrying, and in the mud contained contaminated wastewater environment.And need acreage property to pile up mud, cause the waste of land resource.How solving paper mill sludge becomes the technical barrier of long-term puzzlement paper industry.
Summary of the invention:
The objective of the invention is to overcome above deficiency and a kind of recovering and reutilizing process for papermaking sludge that makes mud really reach zero-emission, save cost and turn waste into wealth is provided.
The present invention is achieved by the following technical solution: the step of this reuse technology is: mud is directly entered in the sedimentation basin from treatment tank precipitate earlier; Putting into clear water then makes it to become certain density available slurry is arranged; Concentration adjustment before copy in the intensive pond of suction again; Send into after the adjustment and copy forebay and good slurry and be mixed into mixed pulp before the online and send into the online header box by stock pump and carry out papermaking, mixed pulp is 0.2%-3.5% through paper machine head box online concentration; The concentration adjustment was controlled by consistency transmitter before described available slurry was copied; Described concentration range is controlled between the 2.5%-7%.Described concentration is 3%.
The present invention has a significant effect:
1, the raw material energy consumes and reduces, and has descended about 30% than original.
2, a pollution treatment difficult problem thoroughly solves, and makes mud really reach zero-emission.
3, save the soil, do not need to waste a large amount of soils every year and stack mud.
4, reduce production costs, if the annual paper plant that produces 3 tons saves about 7,000,000 yuan of costs.
5, technology is simple, and equipment cost is low.
Description of drawings:
As Fig. 1 is the recovering and reutilizing process for papermaking sludge flow chart.
The specific embodiment:
As shown in Figure 1, mud is directly precipitated in the suction sedimentation basin from treatment tank; Through post precipitation half an hour, put into clear water and make it to become certain density available slurry is arranged; Concentration adjustment before copy in the intensive pond of suction again; Through consistency transmitter control, make it concentration and be controlled at 3%, to send into after the adjustment and copy forebay and good slurry and be mixed into mixed pulp before the online and send into the online header box by stock pump and carry out papermaking, mixed pulp is 3% through paper machine head box online concentration.This technology makes original inflow river course and needs to handle the good raw material that the refuse of stacking becomes the paper industry sustainable development.
Claims (4)
1, a kind of recovering and reutilizing process for papermaking sludge is characterized in that its step is: mud is directly entered in the sedimentation basin from treatment tank precipitate earlier; Putting into clear water then makes it to become certain density available slurry is arranged; Concentration adjustment before copy in the intensive pond of suction again; Send into after the adjustment and copy forebay and good slurry and be mixed into mixed pulp before the online and send into the online header box by stock pump and carry out papermaking; Mixed pulp is 0.2%-3.5% through paper machine head box online concentration.
2, a kind of recovering and reutilizing process for papermaking sludge as claimed in claim 1, it is characterized in that described available slurry copy before the concentration adjustment control by consistency transmitter.
3, a kind of recovering and reutilizing process for papermaking sludge as claimed in claim 1 is characterized in that described concentration range is controlled between the 2.5%-7%.
4, a kind of recovering and reutilizing process for papermaking sludge as claimed in claim 3 is characterized in that described concentration is 3%.
