本发明涉及焦炉除尘技术领域，尤其涉及一种用于对全封闭焦炉逸散烟尘收集处理的横向多支撑全封闭焦炉烟尘收集系统。The invention relates to the technical field of coke oven dust removal, and in particular to a transverse multi-support fully enclosed coke oven smoke and dust collection system for collecting and processing escaping smoke and dust from a fully enclosed coke oven.
背景技术Background technique
近年来,随着新的《炼焦炉大气污染物排放标准》开始执行，环保要求越来越严格,对于烟尘及废气等污染物的排放要求也随之大幅度提高。焦炉的污染物排放既包括了煤尘、焦尘，又含有有毒气体，一直是环保部门重点监察的领域。虽然多年以来已经开发出装煤除尘系统、出焦除尘系统等烟尘有组织收集处理系统，但对于焦炉炉门窜漏、炉顶装煤孔不严密、上升管临时排放、炉门开关时偶发产生的无组织污染物排放仍无法避免。In recent years, with the implementation of the new "Coke Oven Air Pollutant Emission Standards", environmental protection requirements have become more and more stringent, and the emission requirements for pollutants such as smoke and exhaust gas have also increased significantly. The pollutant emissions from coke ovens include coal dust, coke dust, and toxic gases, which have always been a key area of supervision by environmental protection departments. Although organized smoke collection and treatment systems such as coal loading dust removal systems and coke discharge dust removal systems have been developed over the years, there are still problems with coke oven door leakage, loose coal loading holes on the top of the furnace, temporary emissions from the riser pipe, and occasional accidents when the furnace door is opened and closed. The resulting unorganized pollutant emissions cannot be avoided.
对于焦炉逸散烟尘的处理，最实用有效的解决办法就是通过一个大型罩体把焦炉整体封闭越来，其排放的高温气体及烟尘会向罩体顶部汇聚，这样就可以进行集中收集和处理了。因此，如何设计出一种用于全封闭焦炉系统中，对焦炉逸散烟尘进行集中收集，且不对生产车辆和炉体设备产生影响的全封闭焦炉烟尘收集系统，就成为本发明的重要目标。For the treatment of escaping smoke and dust from coke ovens, the most practical and effective solution is to seal the coke oven as a whole with a large cover. The high-temperature gas and smoke emitted by it will converge towards the top of the cover, so that centralized collection and collection can be carried out. Dealt with it. Therefore, how to design a fully enclosed coke oven smoke collection system that is used in a fully enclosed coke oven system to centrally collect the escaping smoke and dust from the coke oven without affecting the production vehicles and furnace equipment becomes the key of the present invention. important goals.
传统的焦炉烟尘收集系统主要存在如下问题：The traditional coke oven smoke collection system mainly has the following problems:
1)传统的焦炉没有逸散烟尘收集装置，由于焦炉处于完全开放的环境中，既有的除尘系统只能对有组织排放的出焦烟尘和装煤除尘进行收集，无法对焦炉无组织排放的逸散烟尘进行收集，造成大气污染，无法满足新的环保要求；1) Traditional coke ovens do not have fugitive dust collection devices. Since the coke ovens are in a completely open environment, the existing dust removal system can only collect organized emissions of coke discharge smoke and coal loading dust, but cannot collect unorganized dust from the coke ovens. The fugitive smoke and dust emitted are collected, causing air pollution and failing to meet new environmental protection requirements;
2)目前有的焦炉新设置了烟尘收集装置(如申请公布号为CN107828430A的中国专利公开的“一种焦炉除尘罩”)，但其只是在炉顶设一个半封闭的罩子，只能对焦炉炉顶逸散的烟尘进行收集，无法同时对焦炉机侧、焦侧的逸散烟尘进行收集，因此也不适用于全封闭焦炉使用，且无法满足新的环保要求。2) At present, some coke ovens are equipped with new smoke and dust collection devices (such as "a coke oven dust cover" disclosed in the Chinese patent application publication number CN107828430A), but it only has a semi-enclosed cover on the top of the furnace, which can only Collecting the smoke and dust escaping from the top of the coke oven cannot collect the smoke and dust escaping from the machine side and the coke side of the coke oven at the same time. Therefore, it is not suitable for use in fully enclosed coke ovens and cannot meet new environmental protection requirements.
