【摘要】：天津港焦炭专业化泊位是我国首个焦炭专业化泊位，是天津港“北煤南移”战略的重要标志，，具有专业化、自动化程度高等特点，并为我国首次设计建造。但该系统由于前期设计存在缺陷，在其投入运行后逐渐出现了诸如设备磨损程度较重、系统作业过程中煤尘污染控制效果不理想等实际问题，严重影响了系统的作业效率、作业质量，工作的适应性、安全性，以及设备完好率等指标。本文结合天津港焦炭码头日常作业的实际情况，从提高设备使用效率、改善煤场及周边地区扬尘污染状况两方面入手，创新研究出一整套物料防破碎、设备防磨损和抑尘改进措施，使设备更好地发挥性能，提高工作效率，合理适应北方港口焦炭专业化码头作业的实际需要。该项目通过对现场设备的重新设计、改造和调试，经过反复试验、测量和数据比对，最终完成了三项内容两大方面的研究工作。具体研究成果包括：对卸车坑物料防破碎格栅进行重新设计和改造，有效减少了在卸料过程中物料对设备所造成的冲击，降低设备的磨损程度；运用装船机柔性布料技术，新型设计的装有接料板和导料板软卸料转接塔，以及装船机焦炭防破碎机头装置，很好地降低了物料在溜筒中的破损率；结合北方气候特点以及天津港焦炭专业化码头的主要污染物特点，将污染源随动抑尘、人工造雾、人工造雪技术引入原有洒水除尘系统，完成全天候抑尘系统的升级改造。通过焦炭专业化作业系统关键技术的研究和实际推广应用，焦炭码头专业化系统的设备装卸作业质量、效率和环境优化程度等都得到了明显的改善，同时也创造了一定的经济效益，并为提升天津港焦炭码头的港口竞争力提供了技术保证。该项目的研究也为港口专业化设备的设计与改造提供了有益的参考。
[Abstract]:The specialized berth of coke in Tianjin Port is the first specialized berth of coke in our country. It is an important symbol of the strategy of "moving coal from north to south" in Tianjin Port and has the characteristics of specialization and high degree of automation. It is designed and built for the first time in our country. However, because of the defects in the previous design, the system has gradually appeared such as serious equipment wear after it was put into operation. The actual problems of coal dust pollution control in the process of system operation are not ideal, which seriously affect the efficiency, quality, adaptability and safety of the system. Combined with the actual situation of daily operation of Tianjin Port coke wharf, this paper starts from two aspects: improving the equipment use efficiency and improving the dust pollution in coal yard and surrounding area. A set of measures to prevent materials from crushing, equipment to prevent wear and dust and dust suppression were developed to improve the performance of the equipment, to improve its working efficiency and to meet the practical needs of the specialized coke wharf operation in the northern port. The project through the field equipment re-design, transformation and commissioning, after repeated testing, measurement and data comparison. Finally, three contents and two major aspects of the research work were completed. The specific research results include: the anti-crushing grille of unloading pit material is redesigned and reformed. Effectively reduce the impact of the material on the equipment in the discharge process, and reduce the wear degree of the equipment; By using the technology of flexible loading machine, the new type of soft unloading tower with loading plate and guide plate, and the head device of coke crusher for loading machine, the damage rate of material in the roller is reduced very well. Combined with the northern climate characteristics and the main pollutant characteristics of Tianjin Port coke specialized wharf, the pollution sources are followed by dust suppression, artificial fogging, artificial snow making technology into the original sprinkler dust removal system. Complete all-weather dust suppression system upgrade. Through the research and practical application of the key technology of coke specialized operation system, the equipment handling quality, efficiency and environmental optimization degree of coke terminal specialized system have been improved obviously. At the same time, it also creates certain economic benefits and provides technical guarantee for enhancing the port competitiveness of Tianjin Port coke wharf. The research of this project also provides a useful reference for the design and transformation of port specialized equipment.
