松香厂如何提高回收率
Gum rosin factory how to increase the recovers rate
松香厂在进行松香生产的过程中， 基本上都是要排放大量的中层脂液，且中层脂液的排放量一般占到松脂原料的总量的4.0%左右，在这些中层脂液中，松香含量占35%，松节油占30%， 杂质占15%， 水占20%; 如果一个松香厂年产松脂2000吨，那么在它排放的中层脂液中，松香就有2000x4.0%x35%=28吨，这些松香99%都只能提炼成黑香出售，由于黑香最多只能卖正品一级香60%的价钱，若按每吨正品一级香15000元/吨计，那么黑香只能9000元，也就是说每吨差价达6000元，若能把这些黑香全部变成一级香，那么，28吨香可增加价值：28 x 6000元=168000元。
更可怕的还在后面：在这些中层脂液中，松节油占30%，我可以负责任的说，90%以上的松香企业都未算过这笔账。由于在中层脂液排放过程中，一般温度都在80～90℃，加上中层脂液回收池都是露天设计，特别是在炎热的夏天，排放到废渣池中的中层脂液，其松节油90%以上都挥发跑掉了，剩下的仅有不到10%重油和松香部份。如果按每年生产2000吨松脂计，你知道在废渣池中跑掉多少松节油吗？中层脂液占原料4.0%， 松节油在中层脂液中占30%， 那么跑掉的松节油就是：2000吨 x 4.0% x 30%=24吨！ 也就是说一年生产2000吨松脂原料，在不起眼的废渣池里，每年跑掉的松节油就有24吨之多，松节油的价格按16000元/吨计，每年在废渣池中损失的人民币就是24 x 16000元/吨=384000元，如果年产松脂3000吨、4000吨，就更是不得了！当你看到这些数字的时候，不知道松香企业的老板信会有何感想！
岑溪市桂海机械厂经过多年的潜心研究与实践，现已开发出最新一代中层脂液回收技术：“中层脂液压滤机”（提示：本压滤机的滤板结构、压滤系统是经过精心设计的，它与市面上的一般压滤机有着本质的区别，且已申请并获得国家专利，仿冒者必究！）该回收技以术的主要内容概括起来就三个字：“快”、“精”、“回”。所谓快，也就是在中层脂液刚刚排放出来的是时候，脂液尚未变质，松节油尚未挥发的时候，立即把中层脂液收集到一个密闭的收集罐内，再通过精心设计的液压，过滤设备，经过200目滤布的高压过滤，把中层脂的杂质、松香松松节油（脂液）和水进行分离。“回”也就是把已分离出杂质和水的纯净脂液重新循环到松香生产系统中（不会对松香质量产生影响）。就样，黑香没有了，松节油也跑不了，废渣池，废水干净了，回收率提高了（平均可提高2%左右）。效益出来了，环境也大大改善了。那些对废水排放，环保要求高的企业家特别适用。
回收技术已先后在广东、广西、湖南，江西,四川等地安装了二十多套设备并投入使用，效益显著！

During the gum rosin producing, there will be a large quantity of residue be discharged, and generally speaking, such residue will account for 4.0% of the total crude gum material, among them, the content of gum rosin is around 35%, turpentine oil is 30%, impurity 15% and the rest 20% of water. If a gum rosin factory consumed 2000 MTS of crude gum in a year, then the residue that be discharged will include gum rosin 2000 x 4.0% x35%=28 MTS, 99% of this gum rosin will be made into black gum rosin, and the highest price for black gum rosin is no more than 60% of the normal one, if all this black gum rosin can be turned into normal gum rosin, a great money will be saved.
What even more beyond expectation is, there are around 30% of turpentine oil was included in these residue, that means there are around 2000 x 4.0% x 30% MTS of turpentine oil was escaped with the residue! If a gum rosin factory consumes 2000 MTS crude gum in a year, there are 24 MTS of the turpentine oil was lost, if yearly consumption is 3000MTS, 4000MTS or larger, that is really a quite large number.
After years research and practice, our factory has developed the newest generation of residue recovery technology, that is “residue pressure filter” (Remark: this pressure filter is essential difference from the other ones and has obtained the national patent, counterfeit will be sued!)
The main working principle of this residue pressure filter is that when the residue was discharged then collects them into an airtight collecting tank immediately before metamorphic and turpentine oil has not volatilized, then through the well-designed hydraumatic, filter plant, after the high voltage filtering by the filter cloth which is 200-mesh sieve, and the impurity, turpentine oil, gum rosin and water was separated, then the separated gum rosin and turpentine oil was once again be put into the gum rosin production system. Then, there will be not any black gum rosin, turpentine oil also be kept, and the residue, waste water was also been cleaned, the recovery rate was increased. (the average increased recovery rate is 2%). And the environment was also greatly improved.
This recovery equipment has been installed and used in many factories of Guangdong, Guangxi, Hunan, Jiangxi, Sichuan etc., totally more than 20 sets.
