技术领域technical field
本发明属于有机废液实验设备技术领域,涉及一种实验室有机废液裂解系统。The invention belongs to the technical field of organic waste liquid experimental equipment, and relates to a laboratory organic waste liquid cracking system.
背景技术Background technique
随着我国科学技术快速发展,高校、科研机构与企业的实验室不断扩建,实验室的种类、数量与规模也不断壮大,随之而来的则是实验室废弃物所带来的污染问题。实验室废弃物主要包括:固体废弃物,废液,废气,以及病毒和致病菌的生物性污染物等。高校实验室废弃物具有高毒性,高危害性,但环保部门并未列入环保检测的项目,即使列入,也因量小、易被生活污水稀释而难于检测到。With the rapid development of science and technology in my country, the laboratories of universities, scientific research institutions and enterprises have been continuously expanded, and the types, quantity and scale of laboratories have also continued to grow, followed by the pollution caused by laboratory waste. Laboratory waste mainly includes: solid waste, waste liquid, waste gas, and biological pollutants such as viruses and pathogenic bacteria. University laboratory waste is highly toxic and hazardous, but the environmental protection department has not included it in the environmental protection testing items. Even if it is included, it is difficult to detect due to its small amount and easy dilution by domestic sewage.
实验室废液主要来自各科研单位实验研究室和高等院校的科研和教学实验室。实验室废液有其自身的特殊性质:量少,间断性强,高危害,成分复杂多变。根据废液中所含主要污染物性质,可以分为实验室有机和无机废液两大类。无机废液主要含有重金属、重金属络合物、酸碱、氰化物、硫化物、卤素离子以及其他无机离子等。有机废液含有常用的有机溶剂、有机酸、醚类、多氯联苯、有机磷化合物、酚类、石油类、油脂类物质。相比而言,有机废液比无机废液污染的范围更广,带来的危害更严重。不同的废液,污染物组成不同,处理方法和效果也不相同。实验室废液的处理本着分类收集,就地、及时地原位处理,简易操作,以废治废和降低成本的原则。The laboratory waste liquid mainly comes from the laboratory laboratories of various scientific research units and the scientific research and teaching laboratories of colleges and universities. Laboratory waste liquid has its own special properties: small amount, strong discontinuity, high hazard, and complex and changeable composition. According to the nature of the main pollutants contained in the waste liquid, it can be divided into two categories: laboratory organic waste liquid and inorganic waste liquid. Inorganic waste liquid mainly contains heavy metals, heavy metal complexes, acids and bases, cyanides, sulfides, halogen ions and other inorganic ions. The organic waste liquid contains commonly used organic solvents, organic acids, ethers, polychlorinated biphenyls, organophosphorus compounds, phenols, petroleum and grease substances. In comparison, organic waste liquid has a wider range of pollution and more serious harm than inorganic waste liquid. Different waste liquids have different pollutant compositions and different treatment methods and effects. The treatment of laboratory waste liquid is based on the principles of classified collection, local and timely in-situ treatment, simple operation, waste treatment and cost reduction.
目前处理实验室有机废液的一般方式是集中收集,然后运送到处理机构进行处理,此种方法废弃物处理不及时存在泄漏等安全隐患,且专业处理公司针对各种不同成分的有机废液的处理工艺繁琐,成本高。At present, the general way to deal with laboratory organic waste liquid is to collect it centrally, and then transport it to a treatment institution for treatment. This method of waste disposal is not timely, and there are potential safety hazards such as leakage, and professional treatment companies target various organic waste liquids with different compositions. The processing process is cumbersome and the cost is high.
因此迫切需要能够针对实验室有机废液就地实时处理的一种实验室废液反应系统。Therefore, there is an urgent need for a laboratory waste liquid reaction system that can treat laboratory organic waste liquid in real time.

上述废液反应装置1的工作原理如下:The working principle of the above-mentioned waste liquid reaction device 1 is as follows:
废液和风进入喷液器122后,废液在喷液器122内部被雾化预混后,经喷液器122的末端喷口进入废液反应装置1。废液在废液反应装置1内部对冲混合,同时与一次风进行充分混合,气液混合物充分利用废液反应装置1的壁面和稳焰器121的热量进行蒸发、裂解燃烧反应,提高了反应速率,同时稳焰器121的设置使废液反应装置内的温度分布更加均匀,也有利于反应的快速进行。反应物经过稳焰器121四周的涡轮式通道再次与一次风混合,且稳焰器121涡轮式通道使左侧反应物通过率高,这样在稳焰器121左下方形成向右的旋流,旋流反应物在到达反应体12底部的一次风管时,在一次风的作用下加强了旋流反应物的旋流效果,这样在整个废液反应装置1的反应体12内形成了废液蒸发、裂解燃烧反应的内循环,提高废液反应速率。废液经反应体12处理后,产物中的渣灰颗粒经渣灰收集装置进行收集;反应体12的反应产物在反应体12内进行彻底处理。反应体12自下而上布置有三级导流拱,同时导流拱的设置使产物与二次风、三次风的混合更加均匀,使反应体内的温度分布更加均匀,有利于提高反应速率,同时增加了产物反应的流程,使其反应更加充分、彻底。After the waste liquid and the wind enter the
在整个废液反应装置1内布置有多级温度测点,温度测点和三次(一次风、二次风和三次风)送风量连锁进行耦合控制:通过温度监测获得下部产物的反应程度,进而根据下部产物的反应程度控制一次风、二次风、三次风输送量,达到整体反应装置的自动控制及废液流量变化时的自适应调节。Multi-stage temperature measuring points are arranged in the entire waste liquid reaction device 1, and the temperature measuring points and the tertiary (primary air, secondary air and tertiary air) supply air volume are chained for coupling control: the reaction degree of the lower product is obtained through temperature monitoring, Furthermore, the conveying volume of primary air, secondary air and tertiary air is controlled according to the reaction degree of the lower product, so as to achieve automatic control of the overall reaction device and self-adaptive adjustment when the flow rate of waste liquid changes.
产物经反应体12的充分反应后完成降解,最终产物符合国家排放标准。一、二、三次风都是经过预热后的空气。空气在余热回收装置2内与废液反应装置1的最终产物进行热量交换,预热空气输送至整个废液反应装置1参与反应。最终产物经过余热回收装置2的初步降温,经过烟气急冷脱硫一体化装置3的两级急冷脱硫,使烟气温度降到规定范围,同时除掉部分细小粉尘,之后流经烟气脱水装置4,脱除烟气中所含的水分,最后经过烟气净化装置5,过滤掉残留的有害成分,达标排放。After the product is fully reacted by the
