- the invention relates to the field of papermaking wastewater treatment and the field of dehydration devices, in particular to a rapid dehydration device suitable for papermaking wastewater and a dehydration method thereof.
- the paper industry uses wood, straw, reeds, rags, etc. as raw materials, and cellulose is separated by high-temperature and high-pressure cooking to make pulp. In the production process, the non-cellulose part of the raw material is finally discharged to become papermaking black liquor.
- the black liquor contains lignin, cellulose, volatile organic acids, etc., which has an odor and is highly polluting.
- Papermaking wastewater is very harmful, among which black liquor is the most harmful, and the pollutants it contains account for more than 90% of the total pollution discharge of papermaking industry. And consume a large amount of dissolved oxygen in water, seriously pollute water sources, and bring harm to the environment and human health.
- the most serious environmental pollution of the middle water is the chlorine-containing wastewater produced in the bleaching process, which poses a serious threat to the ecological environment and human health.
- Papermaking wastewater mainly comes from the two production processes of pulping and papermaking in the papermaking industry. Pulping is to separate the fibers in the plant raw materials, make pulp, and then bleach it. This process will generate a lot of papermaking wastewater; papermaking is to dilute, shape, squeeze, and dry the pulp to make paper. The process is also prone to papermaking wastewater.
- wastewater in addition to harmful chemical inorganic substances, it also contains organic substances such as volatile phenols, precipitated solids, suspended solids, and lignin. After these substances enter the water body with the sewage, the dissolved oxygen in the water body needs to be consumed in the process of microbial decomposition of them, reducing the oxygen content of the water body, thereby affecting the growth and reproduction of fish and other organisms.

Description
本发明涉及造纸废水处理领域以及脱水装置领域，尤其涉及一种适用于造纸废水快速脱水装置及其脱水方法。
造纸工业使用木材、稻草、芦苇、破布等为原料，经高温高压蒸煮而分离出纤维素，制成纸浆。在生产过程中，最后排出原料中的非纤维素部分成为造纸黑液，黑液中含有木质素、纤维素、挥发性有机酸等，有臭味，污染性很强。造纸废水危害很大，其中黑液是危害最大的，它所含的污染物占到了造纸工业污染排放总量的90％以上，由于黑液碱性大、颜色深、臭味重、泡沫多，并大量消耗水中溶解氧，严重地污染水源，给环境和人类健康带来危害。而中段水对环境污染最严重的是漂白过程中产生的含氯废水，对生态环境和人体健康造成严重威胁。
造纸废水主要来自造纸工业生产中的制浆和抄纸两个生产过程。制浆是把植物原料中的纤维分离出来，制成浆料，再经漂白，这个过程会产生大量的造纸废水；抄纸是把浆料稀释、成型、压榨、烘干，制成纸张，这个过程也容易产生造纸废水。在造纸工业污水中，除了含有有害的化学无机物，还含有挥发酚、沉淀固形物、悬浮物、木质素等有机物。这类物质随污水进入水体后，在微生物对它们的分解过程中，需要消耗水体中的溶解氧，使水体含氧减少，从而影响鱼类和其它生物的生长繁殖。这样的废水对人体危害极大，其中含有一些重金属元素如铅等，用过的化学药品不会失去药效，仍会对人和环境产生很大的危害，如果造纸厂开在河流附近，纸厂废水就会被排放到但处理后的水对人或环境的影响相比之下小了，对我们来说，谁也不愿意喝被污染了的水，所以在建造纸厂或一些化工厂事都避免建在附近。果树生长发育不良，开花结果 少果，实品质差无营养，水源也污染人也受害造成直接经济损失，这样还会造成一系列的问题。
目前的造纸废水大多是直接进行处理，水中的杂质不能得到有效的清理，且杂质和废水一起进行处理之后，如果一起排放将会造成排放管道的堵塞，另一方面，由于废水的湿度较大，造纸废水的脱干会需要大量的时间，对于一些建筑领域是很难解决的一个难题，因此，亟需一种装置去解决目前所遇到的技术问题。

本发明所采用的第二种技术方案为：
步骤S1：两个驱动轴驱动滤水带转动，当滤水带经过储水箱内的若干传动轴时，通过链轮盘将滤水带两端口贴合，直径较大的颗粒物被阻挡在滤水层外，造纸废水经过滤水层流入吸水层，吸水层将过滤之后的水直接吸收。
步骤S2：滤水带经过分隔辊组，第一挤压辊将滤水层和吸水层分开，滤水层经过第一压合辊组上下两侧，吸水层经过两个第一挤压辊之间的间隙，第一挤压辊将吸水层内的净化水挤出，经过接水槽流入收集箱。
步骤S3：滤水带经过压合辊组，两个第二挤压辊将吸水层和滤水层再次压合，经过上述步骤对对水箱内废水进行收集。
本发明一个较佳实施例中，所述滤水带沿顺时针转动，且所述滤水带在旋转时先经过分隔辊组再经过压合辊组。
本发明解决了背景技术中存在的缺陷，本发明具备以下有益效果：
(1)本发明通过滤水层对过滤储水箱中的造纸废水进行过滤，进一步通过 吸水层对过滤之后的废水进行收集，替代传统的人工脱干方法，经过传动轴带动实现不停歇运转，有效提高水质净化的效率。另一方面，利用储水箱的上方设置的分隔辊组和压合辊组，将吸水层中的水分挤压至收集箱中进行集中收集，实现水资源的再次利用，同时将滤水带整体设置为波浪形，能够对废水箱中的废水起到一定的搅拌作用，从而使更多的废水经过滤水层进入吸水层中，提高脱干效果。
(2)本发明通过安装架中部位置贯穿设置的分隔辊组，使滤水层和吸水层快速分隔开来，利用两个对称设置在同一分隔辊组中的的第一挤压辊，对吸水层充分挤压，使吸水层中得到净化的水快速挤压下落至接水槽中，进而提高净化水的收集效率。同时利用压合辊组再次将滤水层和吸水层压合在一起，更有利于滤水带在传动轴上顺利运转。
(3)本发明通过在第一挤压辊和第二挤压辊中部位置设置的环形凸起，防止滤水带幅宽方向两端设置的配合链条对第一挤压辊和第二挤压辊挤压滤水带时产生影响，进而防止滤水带受到破坏。另一方面，将接水槽与水平面设置有一定夹角，能够进一步保证接水槽中的水快速下落至收集箱中，提高净化水收集速度，且防止水从接水槽另一端溢出。
(4)本发明通过在传动轴两端部位置设置的链轮盘，能够使滤水带和传动轴之间留有一定的间隙，进而保证传动轴在传送滤水带是不会对滤水带造成挤压，防止吸水板中的水被挤压出去。同时，通过配合链条和链轮盘的配合，能够防止滤水带在传动轴上出现打滑现象，进而破坏滤水带，影响其寿命。
(5)本发明中传动轴的轴线互相平行，能够保证滤水带在运转时不会出现偏斜的现象，同时将若干链轮盘整体直径大小设置一致，进一步确保滤水带运转的稳定性。另一方面，驱动轴转速相同，且滤水带沿顺时针转动，能够使滤水带在旋转时先经过分隔辊组再经过压合辊组，进而确保滤水带先经过水分挤 压，再进行压合，有效保证设备的正常运转。
