3. Strengthen management functions After the desulfurization rules and regulations are revised and improved, it is necessary to strengthen the professional management functions of desulfurization on this basis, strictly implement and implement various rules and regulations, and have supervision, inspection, implementation and assessment. (3) personnel training 1. Training objectives At present, although the internship team members in the production preparation stage of our company have received theoretical and on-site follow-up training, the desulfurization knowledge they have learned is far from the actual situation of our company, and there is still a certain distance from the maintenance requirements of our company after the operation and maintenance outsourcing. Therefore, this training plan is formulated through reasonable training arrangement and assessment according to the actual situation of operation and maintenance of ammonia desulfurization. Complete the professional technical and business knowledge training required for the operation and maintenance of ammonia desulfurization in a targeted manner, and meet the technical post grade standard of production work and the requirements of "three practices and three uses" (three practices: familiar with equipment, systems and basic principles; Familiar with operation and accident handling; Familiar with the rules and regulations of this position. Three functions: correct operation and analysis of running state; Be able to find and eliminate faults in time; Can master general maintenance skills), so that trained personnel can be competent for the operation and maintenance of ammonia desulfurization. 2. Training methods Training methods are divided into centralized theoretical training, practice (or simulation training) of the same type of units, and follow-up training of unit commissioning. Theoretical training is carried out by our company's desulfurization specialist and shift supervisor, while theoretical and practical training is carried out by the same type of unit plant specialist. Practical training is carried out in combination with our company's ammonia desulfurization monomer debugging and overall debugging. After the unit enters the trial production operation, the desulfurization operation and maintenance personnel of our company will receive training together with the personnel on duty. Through these trainings, the professional skills of operation and maintenance personnel will be improved to a higher level, so as to achieve the goal of qualified posts within the specified time. The training content of desulfurization post should include equipment system composition, equipment working principle, interlocking protection of system design, equipment start-stop monitoring requirements, routine test of system equipment, general exception handling principles, typical equipment accident cases, etc. , should also include the post daily management requirements and matters needing attention in daily work. 3. Training and implementation (1) desulfurization operation and maintenance personnel training, including professional foundation and professional knowledge training, internship training of the same type of units, etc. (2) The professional foundation and professional knowledge training (simulation training) of desulfurization operation and maintenance personnel should be full-time training; (3) The training content of desulfurization operation and maintenance personnel should be determined in combination with the training outline, equipment and system of Shanxi Zhongneng Lu 'an Waste Heat Power Generation Co., Ltd.. In the design and arrangement of training content, we should adhere to the integration of theory with practice, highlight the training of operational skills and pay attention to the improvement of operational skills;
(4) According to the characteristics of equipment and system, the training mode can be determined according to different training stages, and the combination of independent training and entrusted training should be implemented, focusing on improving the pertinence, effectiveness and practicability of training; (5) Establish an effective training mechanism with Jiangnan Environmental Protection, and conduct on-site training according to the desulfurization personnel configuration of our company. 4.

Desulfurization operation and maintenance capacity planning
Analysis of desulfurization operation and maintenance capacity and promotion planning report
1, desulfurization operation and maintenance capability analysis
The normal, stable, reliable and efficient operation of desulfurization system involves the vital interests of customers. At the same time, whether the desulfurization system is reliable depends on whether the design of the whole desulfurization system is reasonable, whether the equipment is reliable, and more importantly, whether the operation and maintenance meet the requirements. At present, most domestic large-scale units' ammonia desulfurization operation and maintenance projects adopt EPC mode, which has a high degree of technical secrecy and little experience to learn from. However, it is difficult to introduce experienced talents, and the personnel are unstable, which is not conducive to the safety and stability of equipment and has great environmental risks.
