Description

一种铝电解烟气脱硫处理系统 技术领域
本发明涉及烟气脱硫处理的技术领域，特别涉及一种铝电解烟气脱硫处理系统。
背景技术
铝作为一种用途广泛的金属材料，由于其重量轻、耐腐蚀、导电导热性好等特点，常用于飞机船舶制造、电缆制造、散热材料等领域；在现代化铝工业生产过程中常采用电解铝的方法生产铝，由于电解铝的原料内部含有硫、汞等杂质，故电解铝过程中会产生含硫的有毒烟气，因此在电解铝生产过程中需要对有毒烟气进行脱硫净化处理。
电解铝过程中产生的烟气含有热量，传统的电解铝过程烟气中的热量直接排到外界环境中，故排出的废热可能会造成热污染，造成工厂附近的温度升高，易在工厂附近引起热岛效应。
由于电解铝产生的烟气中含有固体颗粒，烟气中的固体颗粒在管道中流动时由于温差、烟气潮湿程度等因素影响，导致烟气中的固体颗粒易粘附在管道内壁上，在烟气输送过程中固体颗粒长时间的堆积易造成管道的堵塞，影响管道的输送效率。
发明内容
为了解决上述问题，本发明采用以下技术方案：一种铝电解烟气脱硫处理系统，包括带有盖板的处理筒，所述的处理筒前端面下侧开设有出液口，盖板上端面右侧开设有进液口，处理筒与盖板之间共同安装有处理机构。
所述的盖板上端面后侧安装有圆柱形结构的进气箱，进气箱上端面开设有进气口，处理筒内部安装有与进气箱相贯通的导引管，处理筒内部设置有处理管，处理管下端与导引管下端之间通过连接管相互连接，盖板上端面左侧固定 安装有与处理管贯通连接的连通管。

优选的，所述的牵引绳穿过连通管设置在连通管上方，连通管上方设置有联动板，联动板下端面左侧与盖板上端面之间安装有联动弹簧杆，且牵引绳固定在联动板下端面，进气箱上通过轴承安装有转动轴，转动轴位于进气箱内部的部分周向均匀安装有多个转动叶片，转动轴位于进气箱外部的部分安装有凸轮，且凸轮位于联动板正下方。
优选的，所述的连通管后侧安装有与其相贯通的排气管，排气管远离连通管的一侧与进气箱贯通连接，且排气管靠近进气箱的一侧安装有单向阀，当烟气在处理管内部未及时通过出气孔排到溶剂内部时，排气管可以对处理管内部多余的烟气导引至进气箱内部，避免烟气不能及时从处理管内部排出引发烟气回流的问题，其中单向阀可以保证排气管内部的烟气单向流动，避免进气箱内部的烟气从排气管进入处理管内部。
优选的，所述的导引管为自上而下延伸的螺旋形结构，可以延长烟气在溶剂内部的流动路径，提高烟气对溶剂的加热效率，且导引管上下两端分别与进气箱、连接管相互卡接，在系统对烟气清理结束后可以将导引管取下，进而可 以通过清洁剂对导引管内部进行清洗处理，避免导引管内部附着的烟气固体颗粒影响导引管的导热性。
优选的，所述的进气口处安装有与进气箱内部贯通的干燥管，干燥管内部填充有干燥剂。
优选的，所述的连接管靠近处理管的一端安装有单向止回阀，避免溶剂通过处理管回流到导引管内部。
优选的，所述的弧形管内部转动安装有用于对牵引线进行导引的定滑轮。
优选的，所述的处理短管与弧形管之间通过螺纹相互连接，当系统对烟气处理结束后，将处理短管与弧形管取下，通过工作人员可以对弧形管内部进行保养，提高弧形管的使用寿命。

进一步地，本发明设计的处理部中，在环形刮板往复移动过程中通过联动块与倾斜斜面相互配合带动调节块前后往复移动，进而调节块通过固定凸起与处理杆相互配合带动锥形连杆对出气孔进行疏通处理，避免烟气中固体颗粒在出气孔发生堵塞，提高烟气的逸出速度。
更进一步地，烟气在进入进气箱时，烟气流动时产生的动能通过转动叶片带动转动轴转动，转动轴转动过程中通过联动弹簧杆与联动板相互配合带动牵引绳上下往复移动，进而可以对烟气流动时产生的动能充分利用，减少能量的损失，同时减少驱动电机的使用，有效的节约了能源。

具体实施方式
以下结合附图对本发明的实施例进行详细说明，但是本发明可以由权利要求限定和覆盖的多种不同方式实施。
参阅图1、图2以及图11，一种铝电解烟气脱硫处理系统，包括带有盖板1的处理筒2，所述的处理筒2前端面下侧开设有出液口21，盖板1上端面右侧开设有进液口11，处理筒2与盖板1之间共同安装有处理机构3。
参阅图3、图4以及图5，所述的盖板1上端面后侧安装有圆柱形结构的进气箱12，进气箱12上端面开设有进气口13，处理筒2内部安装有与进气箱12相贯通的导引管22，处理筒2内部设置有处理管23，处理管23下端与导引管22下端之间通过连接管24相互连接，盖板1上端面左侧固定安装有与处理管23贯通连接的连通管25。
参阅图4，所述的进气口13处安装有与进气箱12内部贯通的干燥管14，干燥管14内部填充有干燥剂15。
参阅图6，所述的导引管22为自上而下延伸的螺旋形结构，可以延长烟气在溶剂内部的流动路径，提高烟气对溶剂的加热效率，且导引管22上下两端分别与进气箱12、连接管24相互卡接，在系统对烟气清理结束后可以将导引管22取下，进而可以通过清洁剂对导引管22内部进行清洗处理，避免导引管22内部附着的烟气固体颗粒影响导引管22的导热性。
继续参阅图6，所述的连接管24靠近处理管23的一端安装有单向止回阀241，避免溶剂通过处理管23回流到导引管22内部。
参阅图7，所述的处理管23由自上而下相互倾斜交错的处理短管26组成，处理短管26圆周面上沿其轴向均匀开设有多组前后对称的出气孔261，且处理短管26之间通过弧形管27相互贯通连接。
所述的处理短管26与弧形管27之间通过螺纹相互连接，当系统对烟气处理结束后，可以将处理短管26与弧形管27取下，以便对弧形管27内部进行保养，延长弧形管27的使用寿命。
参阅图9、图10以及图11，所述的处理机构3包括多个滑动设置在处理短管26内壁的环形刮板31，且左右相邻的出气孔261之间环形刮板31的数量为一个，环形刮板31内部沿与处理管23相垂直的方向设置有连接凸起32，处理管23内部设置有牵引绳33，牵引绳33穿过处理短管26与弧形管27之间并 安装在连接凸起32上，牵引绳33最下侧与连接管24之间安装有连接弹簧34，处理短管26内部设置有与出气孔261相对应的处理部35。
参阅图7以及图8，所述的弧形管27内部转动安装有用于对牵引绳33进行导引的定滑轮271，定滑轮271可以避免牵引绳33与弧形管27内壁相互接触摩擦，对牵引绳33起导引与保护作用。
参阅图11以及图12，所述的处理部35包括前后对称设置在环形刮板31内部的联动块351，处理短管26内部且位于联动块351的左侧均设置有调节块352，调节块352相背面均设置有与联动块351相配合的倾斜斜面，调节块352相背面左侧与处理管23内壁之间均安装有复位弹簧杆353，调节块352左侧均设置有固定凸起354，固定凸起354相背面均设置有与出气孔261一一对应的处理杆355，且处理杆355圆周面自前向后均匀设置有多组周向设置的锥形连杆356。
参阅图2以及图4，所述的牵引绳33穿过连通管25设置在连通管25上方，连通管25上方设置有联动板251，联动板251下端面左侧与盖板1上端面之间安装有联动弹簧杆252，且牵引绳33固定在联动板251下端面，进气箱12上通过轴承安装有转动轴253，转动轴253位于进气箱12内部的部分周向均匀安装有多个转动叶片254，转动轴253位于进气箱12外部的部分安装有凸轮255，且凸轮255位于联动板251正下方。
具体工作时，将出液口21通过密封塞密封，通过进液口11向处理筒2内部倒入溶剂使得溶剂浸没处理管23，再将带有烟气的管道固定在干燥管14上端，烟气通过干燥管14进入进气箱12内部，此时烟气经过导引管22进入处理管23内部，处理管23内部的烟气通过出气孔261进入溶剂中进行净化处理，其中干燥管14内部的干燥剂15可以对烟气的水分进行吸收，避免烟气中的固体颗粒与水蒸气相互融合附着在导引管22内部影响烟气通过导引管22时对溶剂的导热性，烟气在进气箱12内部流动时产生的动能通过转动叶片254带动转动轴253转动，转动轴253转动过程中通过联动弹簧杆252与联动板251相互配合带动牵引绳33上下往复移动，进而可以对烟气流动时产生的动能充分利用，减少能量的损失，同时减少驱动电机的使用，有效的节约了能源使用。
牵引绳33上下往复移动过程中通过连接凸起32与连接弹簧34相互配合 带动环形刮板31对处理短管26内部进行刮除处理，避免烟气中固体颗粒在处理短管26内部堆积造成处理短管26的堵塞，提高处理短管26内部的通透性，当环形刮板31往复移动过程中通过联动块351与倾斜斜面相互配合带动调节块352前后往复移动，进而调节块352通过固定凸起354与处理杆355相互配合带动锥形连杆356对出气孔261进行疏通处理，避免烟气中固体颗粒在出气孔261发生堵塞，提高烟气的逸出速度。
参阅图2，所述的连通管25后侧安装有与其相贯通的排气管256，排气管256远离连通管25的一侧与进气箱12贯通连接，且排气管256靠近进气箱12的一侧安装有单向阀257，当烟气在处理管23内部未及时通过出气孔261排到溶剂内部时，排气管256可以将处理管23内部多余的烟气导引至进气箱12内部，避免烟气不能及时从处理管23内部排出引发烟气回流的问题，其中单向阀257可以保证排气管256内部的烟气单向流动，避免进气箱12内部的烟气从排气管256进入处理管23内部，含硫、汞等的有害烟气在净化后多余的气体从设置在处理筒2后侧的排烟口(图中未示出)排出。
采用上述铝电解烟气脱硫处理系统在对烟气处理过程中，包括以下步骤：第一步、处理准备：将出液口21通过密封塞密封，通过进液口11向处理筒2内部倒入溶剂使得溶剂浸没处理管23，再将带有烟气的管道固定在干燥管14上端。
第二步、烟气泵入：烟气通过干燥管14进入进气箱12内部，此时烟气经过导引管22进入处理管23内部，处理管23内部的烟气通过出气孔261进入溶剂中进行净化处理。
第三步、清扫处理：烟气在进气箱12内部流动时产生的动能通过转动叶片254带动转动轴253转动，转动轴253转动过程中通过联动弹簧杆252与联动板251相互配合带动牵引绳33上下往复移动，牵引绳33上下往复移动过程中通过连接凸起32与连接弹簧34相互配合带动环形刮板31可以对处理短管26内部进行刮除处理。
第四步、系统整理：当烟气处理结束后将密封塞打开，通过现有的收集桶对处理后的溶剂进行收集处理，处理工作结束。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
