Description
技术领域 technical field
本发明涉及石油化工设备技术领域，尤其是一种煤气化污水管线清洗装置。 The invention relates to the technical field of petrochemical equipment, in particular to a coal gasification sewage pipeline cleaning device.
背景技术 Background technique
煤制合成气的灰水，经过四级闪蒸，充分回收热量，然后灰水与添加剂一并送至沉淀池中，使细灰沉降下来，而上部灰水溢流进入低压灰水槽，为了保持灰水中溶解物的平衡，部分灰水需要送往废水处理系统。 The gray water of the coal-to-synthesis gas undergoes four-stage flash evaporation to fully recover the heat, and then the gray water and additives are sent to the sedimentation tank to settle the fine ash, and the upper gray water overflows into the low-pressure gray water tank. The balance of dissolved substances in gray water, part of which needs to be sent to the wastewater treatment system.
由于这部分灰水含有Ca2+、Mg2+、CO3 2-等离子，当超过离子浓度超过其饱和溶度，易出现CaCO3和MgCO3沉淀，最后以垢的形式附着在污水管的管壁，严重时将影响管道的输送的流量。 Since this part of gray water contains Ca 2+ , Mg 2+ , and CO 3 2- ions, when the ion concentration exceeds its saturation solubility, CaCO 3 and MgCO 3 are prone to precipitate, and finally adhere to the sewage pipe in the form of scale In severe cases, it will affect the transport flow of the pipeline.
现常用方法用高压水清洗法和酸洗法。高压水洗清洗法耗时多且成本高；酸洗法存在管道腐蚀问题和酸洗水处理等问题。现在还有一些利用清管器（PIG）进行清理管道的技术，例如中国专利申请201310516180.4，喷射清淤清管器，再如200510132602.3，射流式清管器，都记载了不同的清管器，但是清管器在用于清理煤气化污水管线时，又存在无法清除各种化学沉淀等问题，因此目前急需提供一种合适的煤气化污水管线清理的解决方案。 The commonly used methods are high-pressure water cleaning and pickling. The high-pressure water washing cleaning method is time-consuming and costly; the pickling method has problems such as pipeline corrosion and pickling water treatment. There are still some technologies that use pipe pigs (PIG) to clean pipelines. For example, Chinese patent application 201310516180.4, jet dredging pipe pigs, and 200510132602.3, jet-type pipe pigs, all record different pipe pigs, but When the pipe pig is used to clean the coal gasification sewage pipeline, there are problems such as the inability to remove various chemical deposits. Therefore, it is urgent to provide a suitable solution for the cleaning of the coal gasification sewage pipeline.
