干排渣系统
本技术涉及一种用于锅炉排渣系统,具体涉及一种用于火电厂锅炉干排渣系统。技术背景现有的中国大唐工程公司制造的干排渣系统,是将炉膛燃烧剩余的废料经炉底液压关断门开启落入输送带上,经输送带缓慢的运行将燃烧后的废渣落入碎渣机中,经由碎渣机将大渣碾碎后落入落料斗中,清扫链则将落下的细灰在刮板的配合下将灰送入到落料斗中,输送带和清扫链共同完成了对炉膛燃烧后的废渣的排放。但该系统存在以下几个缺陷:1.如果液压关断门在开启过程中上方的挤压装置未将大渣挤压成小渣,液压关断门在开启过程中会有大量的渣落下,同时不可避免的有硬度高,体积大的渣块从端部落到清扫链工作的层面上,清扫链将渣块缓慢的拉至清扫链驱动端,清扫链啮合在行星轮(齿轮)上,如硬度较高的大渣夹杂在新型轮上,链条若张紧过渡可能会导致链条断裂、错环。2.由于落渣端部离碎渣机距离很近,若碎渣机碎渣不及时,碎渣机装满渣,可能会造成废渣向外溢出的情况,大渣也可能会堵卡在新型轮处,造成1中提到的现象。3.由于该厂采用的锅炉是负压式炉膛,干排渣系统内部也是负压环境,由于干排渣系统封闭性不好,漏风量较大尤其是在端部,在清扫链 ...
