Description

一种污染土壤的修复*** 技术领域
本发明属于土壤污染治理技术领域，尤其涉及一种污染土壤的修复***。
 背景技术
在环保施工领域中，通常涉及到对污染土壤的修复。污染土壤是指位于污染场地内、受到污染的土壤，指因堆积、储存、处理、处置或其它方式（如迁移）承载了有害物质的、对人体健康和环境产生危害或具有潜在风险的空间区域，例如农药、化肥等工厂所在的区域为污染场地，在工厂搬迁之后对场地进行开发利用之前通常需要对污染场地进行污染治理，其中土壤污染治理是一个重要的方面。现有技术中的污染土壤修复方法通常分为原位修复方式和异位修复方式。土壤原位修复技术是指在人为干预的条件下在受污染土壤的原址直接进行污染的修复，而土壤异位修复技术是指将污染土壤从场地提出，然后将污染土壤转移至其它地方进行修复。
对于后一种修复方式即异位修复方式而言，将土壤从场地开挖出来并转移至专用修复场地之后，可以通过人工喷洒修复剂、种菌溶液等对污染土壤进行修复，利用物理、化学和生物等方法转移、吸收、降解和转化土壤中的污染物，使其浓度降低到可接受的水平，或将有毒有害的污染物转化为无害的物质。一般情况下，在污染土壤中通常含有多种挥发性污染成分（有机物成分），在污染土壤进行修复处理的过程中，前述挥发性污染成分会挥发出来，若不进行有效处理，则会导致二次污染（空气污染）。另一方面，促进污染土壤内的挥发性污染成分快速、充分地从土壤中挥发出来本身就是修复的手段之一。
现有技术中通常采用摊铺晾晒的方式促进挥发物的排出，在向污染土壤喷洒修复剂、种菌溶液等时，土壤通常处于堆放的状态。此种修复方式存在如下缺陷：首先，不能实现连续式修复；其次，堆放的土壤不易于与修复剂、种菌溶液等进行充分混合，修复效果较差；再者，前述修复方式难于对挥发物进行收集处理，无法避免空气污染问题。因此，需要对污染土壤的修复***进行结构上的优化设计，以解决前述技术问题
 技术问题

优选地：升降架装置包括外框架，在外框架的内侧安装固定有相对的第一滑道和第二滑道，在外框架的上部通过上转轴安装有前后两个上转轮、下部通过下转轴安装有前后两个下转轮，在前部的上转轮与下转轮之间安装有第一链条，在后部的上转轮与下转轮之间安装有第二链条，在第一链条与第二链条之间安装有多个沿着第一滑道和第二滑道移动的升降组件，升降组件包括托板，在托板的前部和后部均安装有侧支架，在侧支架的外侧设有与滑道配合的滚轮，每个升降组件的两个侧支架采用连接杆连接，连接杆的前后两端分别与第一链条和第二链条的链瓣固定连接。

 有益效果
本发明的优点和积极效果是：
本发明提供了一种结构设计合理的污染土壤的修复***，与现有的污染土壤修复设备/***相比，本发明中的修复***实现了连续式的修复处理过程，污染土壤置入提升装置之后，先由提升装置向上提升，之后下落在铺展装置上，再次提升输送的过程中，污染土壤被逐渐铺展开，之后污染土壤下落在输送装置上，再次提升输送的过程中由摊铺装置摊铺开并且由喷洒装置喷洒修复药剂，之后喷洒了修复药剂的污染土壤向下落入土筐内，土筐由升降架装置提升起来，升降架装置进入集气罩箱后在脱附净化装置的负，压作用下，污染土壤中的挥发物成分加速排出，挥发物成分由脱附净化装置现场进行净化处理，因此本发明中的修复***实现了一种对污染土壤进行连续修复处理的修复处理工艺过程。
由于设置了提升装置、铺展装置和输送装置，令处于堆放状态的污染土壤能够分散开，充分与空气接触，并且在喷洒修复药剂的过程中能够充分与修复药剂接触和混合，因而能够显著提升污染土壤的修复效果。对于结块的污染土壤而言，在下落至铺展装置上并且提升输送的过程中会向下方滚落，因此有效避免了结块的污染土壤向后方转移导致的修复效果不理想问题。通过设置脱附净化装置并且采用可移动的集气罩箱罩设在载有土筐的升降架外部，实现了对污染土壤中挥发物的在线脱附收集以及在线吸附净化处理，因而有效避免了污染土壤中的挥发物进入大气，避免了空气污染。

 本发明的最佳实施方式
为能进一步了解本发明的发明内容、特点及功效，兹举以下实施例详细说明。
请参见图1、图3和图4，本发明的污染土壤的修复***包括支撑框架10，在支撑框架10上通过A型支座15安装有用于对污染土壤进行提升输送的输送装置5。在输送装置5的中部上方安装有用于对污染土壤进行摊铺的摊铺装置3，在输送装置5的前部上方安装有用于向污染土壤喷洒药剂的喷洒装置4，在输送装置5的前部下方安装有防护外罩13，在防护外罩13的内部上方安装有下料漏斗17，在下料漏斗17的下方置有土筐16。
在支撑框架10的后方设有对污染土壤进行提升的提升装置1，在提升装置1与输送装置5之间安装有对污染土壤进行提升和铺展的铺展装置2。在输送装置5的前方安装有对装有污染土壤的土筐进行升降的升降架装置6，在支撑框架10的前方设有能够前后移动且能够令升降架装置6完全进入内部的集气罩箱7。还包括与集气罩箱7连接的、对产生的污染气体进行在线处理的脱附净化装置8。
本发明中修复***的工作原理是：
堆放的污染土壤采用铲车等机具转移到提升装置1内，提升装置1将污染土壤提升输送之后下落到铺展装置2上，由于提升装置1对污染土壤的连续式提升作用以及振动作用，污染土壤以分散的形式落在铺展装置2上并且连续式地向前提升输送，此过程中，大颗粒的污染土壤向后方滚落，避免出现大颗粒土壤向后转移导致的修复效果不理想问题（大颗粒土壤中的有害成分不易挥发出来，也不易于与修复药剂接触混合）；之后污染土壤继续以分散的形式落在输送装置5上并且连续式地向前提升输送，在经过摊铺装置3时受到摊铺作用，输送装置5上的污染土壤进一步被摊铺分散开来，避免由于污染土壤分散不均匀导致的修复效果不理想问题；污染土壤移动到输送装置5的前部上方时，从喷洒装置4接收雾化的修复药剂，之后混拌了修复药剂的污染土壤向下掉落进入下方的下料漏斗17内，之后从下料漏斗17的底部排出进入土筐16内；之后装有污染土壤的多个土筐16向升降架装置6上转移并装载，当升降架装置6上装载了多个土筐16时，集气罩箱7向后移动令升降架装置6完全进入集气罩箱7内；脱附净化装置8持续产生负压脱附作用，即连续式地从集气罩箱7内抽取气流，令集气罩箱7内形成负压环境，加速污染土壤中的挥发物成分挥发出来，产生的污染气体由脱附净化装置8提供在线吸附净化处理，截留污染气体中的污染成分，对吸附净化处理后的洁净气流进行直接排放。
多个土筐16进行循环使用，需要采用人工方式配合小型叉车等机具进行操作。具体地：人工采用叉车机具将空的土筐16置入A型支座15的内部、防护外罩13的后方，在支撑框架10的中部安装有对土筐16进行向前推移移动的推送油缸12，在推送油缸12的推送作用下，土筐16单次向前移动一个工位，土筐16移动到防护外罩13的内部、下料漏斗17的下方，下料漏斗17内接收的混拌了修复药剂的污染土壤落入下方的土筐16内，之后推送油缸12继续动作，后方的土筐16将前方的土筐16向前顶动移动一个工位，则前方的土筐16转移到升降架装置6上；如此重复，升降架装置6上装载多个土筐16；之后集气罩箱7后移令升降架装置6完全进入其内部，完成负压脱附过程之后，集气罩箱7向前移动直至与升降架装置6完全分离；之后，人工采用叉车机具将升降架装置6上的各土筐16连同内部的处理后土壤逐个转移至倾倒场所，将土筐16内的处理后土壤倾倒出来，空置的土筐16再置入A型支座15的内部，如此实现循环使用。
支撑框架10用于提供稳定的支撑作用，采用金属型材焊接搭建而成，整体成扁平的长方体形状，令铺展装置2、输送装置5和升降架装置6的高度大于提升装置1的高度，并且令升降架装置6进入集气罩箱7时近似位于集气罩箱7的内部空间的中部。
考虑到铺展装置2、输送装置5和升降架装置6等在运转的过程中会有土壤向下洒落，因此本实施例中，在支撑框架10的顶部铺设安装厚金属板构成底板，将铺展装置2、输送装置5、升降架装置6、A型支座15和防护外罩13安装固定在该底板上，这样下落的土壤会落在平整的底板上，便于对修复***进行定期清理。底板的另一个作用是：令土筐16在平整的平面上向前移动，有效避免卡阻问题。
防护外罩13由相对的两个带孔的侧板构成，侧板的底部与前述底板焊接固定，设置防护外罩13的目的是将下料漏斗17、土筐16等封闭在内部，避免异物进入，同时能够提升***运行的安全性。
土筐16为长方体形状，顶部敞口，各侧壁上带有气孔，为了减少土壤漏出，底板上不设气孔。装载到升降架装置6上并且进入集气罩箱7内进行负压脱附时，土筐16内的污染土壤产生的挥发物从顶部敞口以及侧壁上的气孔排出。
推送油缸12以横置的姿态安装在支撑框架10的中部、底板的下方，在其活塞杆的前端安装推板，推板采用销轴与活塞杆的前端铰接连接并且在销轴上安装有扭簧，在正常状态下，推板处于直立的状态。在底板上设有上下贯通的条形滑道，推板的上部位于条形滑道内，这样当推送油缸12的活塞杆向前伸出时，直立形态的推板抵靠在土筐16的后部底部上，活塞杆继续向前伸出时推动土筐16向前移动，活塞杆完全伸出时土筐16向前移动一个工位（单次移动距离等于土筐16的宽度值），当活塞杆回缩时，由于后方土筐16的阻挡，推板被拨动倾转、扭簧发生形变，在回退的过程中，推板沿着后方土筐16的底部移动，当推板移动到土筐16的后部边缘后方时，随着土筐16对推板压持作用的消失，在扭簧弹力的作用下，推板恢复直立状态，准备下一次对土筐16施加向前推送作用。
考虑到有少量的大颗粒污染土壤会转移到输送装置5上并且喷洒修复药剂后从输送装置5的前部落入下料漏斗17内，这些大颗粒污染土壤可能堵塞下料漏斗17的底部出口，或者即使未堵塞下料漏斗17的底部出口，也会导致内部挥发物不能充分排出的问题，因此本实施例中，在防护外罩13的两个侧板之间、下料漏斗17的上方设置一个过滤篦子18对污染土壤进行过滤。如图4中所示，过滤篦子18采用金属杆焊接构建，相邻的金属杆之间形成供污染土壤通过的空隙，超过这个空隙大小的土壤颗粒被截留在上方，定期以人工的方式从侧方进行清理即可，保证过滤篦子18的土壤通过能力。
A型支座15用于对输送装置5的前部进行稳定支撑，包括相对设置的两个A型架，防护外罩13的两个侧板分别位于两个A型架的内侧。如图4中所示，在一侧的A型架的底部设置窗口，空置的土筐16就从这个窗口置入内部，值得注意的是，位于该A型架内侧的防护外罩13的侧板的后部可以切割去除一部分，避免对该A型架上窗口的遮挡，避免对土筐16通过窗口进入内部造成阻碍。
请参见图2，可以看出：
提升装置1包括前部带有缺口的料斗1-1，在缺口内安装有输送带组件1-3，料斗1-1置于支撑框架10后方的地面上，保证稳定性，输送带组件1-3用于将料斗1-1内的污染土壤向上提升输送。堆放的、相对干燥的污染土壤采用铲车等机具装载到料斗1-1内，之后输送带组件1-3以连续的方式、分散地将料斗1-1内的土壤提升输送。
如图中所示，输送带组件1-3包括输送带框架，在输送带框架上安装有上下两个轴辊且在轴辊之间安装有输送带，在输送带上等间距地设有提升板，在输送带框架的底部安装有驱动轴辊的提升电机1-2、顶部安装有上部支架1-5，在上部支架1-5的内侧安装有下料斜板1-4。上部支架1-5的作用有两个，一是对下料斜板1-4进行稳定安装，二是与前方的在铺展装置2固定连接。在提升电机1-2的驱动作用下，输送带带动提升板移动，提升板从污染土壤中通行时，一部分污染土壤被提升板提升起来，到达输送带的顶部后，沿着下料斜板1-4向前滑落。通过控制提升电机1-2的运转，实现对输送带组件1-3运行速度的控制。
请参见图3、图4和图5，可以看出：
铺展装置2包括相对设置的两个铺展侧护板2-3，在铺展侧护板2-3之间安装有铺展组件，铺展侧护板2-3的底部与支撑框架10上的底板固定连接，通过将铺展组件设置在铺展侧护板2-3的内部，有效避免异物进入并且提升本修复***运转的安全性。
本实施例中，在两个铺展侧护板2-3的后部顶部之间安装有一个横梁，提升装置1的上部支架1-5的前部与该横梁固定连接。
铺展组件包括上下两个铺展转轴2-2，在铺展转轴2-2之间安装有铺展输送链2-1，铺展转轴2-2带动铺展输送链2-1移动，将污染土壤向前提升输送。具体地：在铺展转轴2-2的两端安装有链轮，在同侧的链轮之间安装有链条，在两个链条横向对应的链瓣之间安装有连杆，在相邻的连杆之间安装有链板。图3和图4中铺展输送链2-1的相邻连杆之间的链板未示出。
值得注意的是，提升装置1的输送带组件1-3的移动速度应该小于铺展装置2的铺展输送链2-1的移动速度，这样从提升装置1转移到铺展装置2上的污染土壤能够在铺展输送链2-1上分散开。
从提升装置1转移到铺展装置2上的污染土壤可能含有一些大颗粒，由于铺展输送链2-1是斜置的即具有一定的坡度，因此大颗粒的污染土壤在转移到铺展装置2上之后、向前方提升移动的过程中，会向后方滚落，最终从铺展输送链2-1的后端排出，这有效避免了由于大颗粒的污染土壤向后方转移导致的修复效果不理想问题。
本实施例中，在铺展装置2的下端还安装有对大颗粒的污染土壤进行剪切并同时为铺展装置2提供振动效果的剪切振动装置9。如图3和图5中所示，剪切振动装置9包括剪切振动齿9-2和驱动组件9-3，在剪切振动齿9-2的下方设有接收板9-1。剪切振动装置9包括上下两个叠置的带有剪切齿的齿板，其中下方的齿板为固定式齿板，与铺展装置2的两个铺展侧护板2-3固定连接，上方的齿板在驱动组件9-3的驱动作用下左右往复平移移动，因而两个齿板的各剪切齿发生交错动作，产生剪切作用。
如图5中所示，驱动组件9-3包括与上方齿板的中部固定连接的、椭圆形的受驱套管，在受驱套管的顶壁和底壁上设有齿条，驱动组件9-3还包括与铺展装置2的两个铺展侧护板2-3固定连接的轴套，在该轴套内安装有转轴，该转轴后端的外壁上设有扇形齿部，驱动组件9-3还包括安装在其中一个铺展侧护板2-3上的剪切振动驱动轴9-4，剪切振动驱动轴9-4的内端与前述转轴的前端之间采用锥齿轮组传动。
剪切振动驱动轴9-4将外部驱动作用通过锥齿轮组传递给转轴，转轴在转动的过程中其扇形齿部先后与受驱套管上部和下部的齿条啮合，因而受驱套管带动上方的齿板作横向往复移动，产生剪切破碎作用。另一方面，剪切振动装置9在运动的过程中会产生一定的振动效果，该振动效果传递给铺展装置2。提升装置1将污染土壤分散地转移到铺展装置2上之后，前述振动效果促进污染土壤在铺展装置2进一步分散开来，转移到铺展装置2上的大颗粒污染土壤会向后方滚落，到达铺展装置2的底部时会滚落到剪切振动装置9上被剪切振动齿9-2剪切破碎，破碎后的土壤落在下方的接收板9-1上，定期由人工采用工具将接收板9-1上的土壤转移到提升装置1的料斗1-1内。
请参见图3和图4，可以看出：
输送装置5包括由A型支座15支撑的、相对设置的两个输送侧护板5-3，在两个输送侧护板5-3之间安装有输送组件，两个输送侧护板5-3的底部与底板固定连接，通过将输送组件设置在输送侧护板5-3的内部，有效避免异物进入并且提升本修复***运转的安全性。
输送组件与铺展组件的结构是相同的，结构上包括上下两个输送转轴5-2，在输送转轴5-2之间安装有转移输送链5-1。输送转轴5-2带动转移输送链5-1移动，将污染土壤向前提升输送。具体地：在输送转轴5-2的两端安装有链轮，在同侧的链轮之间安装有链条，在两个链条横向对应的链瓣之间安装有连杆，在相邻的连杆之间安装有链板。图3和图4中转移输送链5-1的相邻连杆之间的链板未示出。
请参见图6，可以看出：
摊铺装置3包括分别安装在两个输送侧护板5-3上的、相对的两组轴座，在其中一组轴座上安装有第一辊轴3-3、在另一组轴座上安装有第二辊轴3-4，在第一辊轴3-3与第二辊轴3-4之间安装有移动带3-5，在移动带3-5上安装有多个摊铺毛刷束3-6。摊铺毛刷束3-6选取为硬质塑料毛刷束或者金属毛刷束，第一辊轴3-3和第二辊轴3-4驱动移动带3-5移动，多个摊铺毛刷束3-6随动动作，位于下方的摊铺毛刷束3-6从转移输送链5-1的表面通过时对转移输送链5-1上的污染土壤进行主动摊铺，令堆积厚度比较大的地方的污染土壤移动到其它位置，因而避免了土壤在转移输送链5-1上的堆积。
还包括传动连接的摊铺驱动轴3-1和摊铺传动轴3-2，摊铺传动轴3-2与第一辊轴3-3或第二辊轴3-4采用锥齿轮组传动连接。摊铺驱动轴3-1将外部驱动作用通过摊铺传动轴3-2传递给第一辊轴3-3或第二辊轴3-4，驱动移动带3-5和摊铺毛刷束3-6移动，产生对土壤的摊铺作用。
喷洒装置4包括安装在输送装置5前部上方的修复药剂盒，在修复药剂盒的底部安装有成阵列式布置的多个雾化喷嘴，由修复药剂箱和增压泵构成的药剂供应装置通过高压管路与修复药剂盒的入口连接，增压泵将修复药剂箱内的修复药剂以高压的状态输送至修复药剂盒，修复药剂经由多个雾化喷嘴向下方通行的污染土壤喷淋。
请参见图7，可以看出：
升降架装置6包括外框架6-1，外框架6-1采用金属型材构建而成，底部与支撑框架10上的底板固定连接。
在外框架6-1的内侧安装固定有相对的第一滑道6-3和第二滑道6-7，在外框架6-1的上部通过上转轴6-11安装有前后两个上转轮、下部通过下转轴6-8安装有前后两个下转轮，在前部的上转轮与下转轮之间安装有第一链条6-10，在后部的上转轮与下转轮之间安装有第二链条6-9。还包括驱动上转轴6-11或者下转轴6-8转动的升降电机6-2，在升降电机6-2的驱动作用下，第一链条6-10和第二链条6-9同步移动。
在第一链条6-10与第二链条6-9之间安装有多个沿着第一滑道6-3和第二滑道6-7移动的升降组件，土筐16移动到升降组件上，并且随着升降组件作循环式的升降移动。升降组件包括托板6-4，在托板6-4的前部和后部均安装有侧支架6-5，在侧支架6-5的外侧设有与滑道配合的滚轮6-6，升降组件作循环式升降移动时，滚轮6-6在第一滑道6-3或第二滑道6-7内移动，提升作升降移动时的稳定性。
每个升降组件的两个侧支架6-5采用连接杆6-12连接，如图中所示，连接杆6-12位于两个侧支架6-5的顶部中部之间，连接杆6-12的前后两端分别与第一链条6-10和第二链条6-9的链瓣固定连接。
推送油缸12将土筐16横向推送到升降组件的托板6-4上，之后升降电机6-2启动，链条带动升降组件移动一个工位（后方的升降组件上升一个工位，相应地前方的升降组件下降一个工位），下一个土筐16被推送至底部的升降组件的托板6-4上，如此操作将土筐16逐个装载到升降架装置6上，装载操作均施加给升降架装置6后方底部的那个升降组件。在此过程中，升降架装置6前方的各土筐16采用叉车机具逐个卸载，转移至倾倒场所将处理后的土壤倾倒处理，清空土筐16后转移至土筐16的上料位置，卸载操作均施加给升降架装置6前方底部的那个升降组件。
本实施例中，在支撑框架10的中部安装有驱动电机11，具体地驱动电机11安装在底板的中部位置，铺展装置2、摊铺装置3、输送装置5和剪切振动装置9均由驱动电机11提供动力，即本修复***的主要设施采用单一驱动。
如图中所示，在驱动电机11的输出轴上安装有多槽式皮带轮，在输送装置5上端的输送转轴5-2的外端安装有皮带轮，该皮带轮与驱动电机11的皮带轮采用皮带传动连接。在支撑框架10的中后部通过另一个支座支撑安装摊铺装置3的摊铺驱动轴3-1，在摊铺驱动轴3-1的两端均安装多槽式皮带轮，在铺展装置2的上端的铺展转轴2-2的外端安装有皮带轮且该皮带轮与摊铺驱动轴3-1上的同侧皮带轮采用皮带传动连接，在摊铺传动轴3-2的外端安装有皮带轮且该皮带轮与摊铺驱动轴3-1上的同侧皮带轮采用皮带传动连接，在剪切振动驱动轴9-4的外端安装有皮带轮且该皮带轮与摊铺驱动轴3-1上的同侧皮带轮采用皮带传动连接。因而，铺展装置2、摊铺装置3、输送装置5和剪切振动装置9四者是同步动作的。
请参见图8，可以看出：
脱附净化装置8包括活性炭吸附箱8-6、输入主管道8-5、输出主管道8-4、主风机8-8和烟囱8-9，其中活性炭吸附箱8-6并列设置有多个以保证对污染废气的在线吸附净化处理效果。还包括带有楼梯的平台支架8-3，各活性炭吸附箱8-6安装在平台支架8-3上，在活性炭吸附箱8-6的侧部设有箱门，这样便于维保人员登上平台支架8-3对各活性炭吸附箱8-6进行维护作业，具体地，打开活性炭吸附箱8-6的侧部箱门，将内部的活性炭组件取出并置换新的活性炭组件。
各活性炭吸附箱8-6的顶部入口与输入主管道8-5对接连接、底部出口与输出主管道8-4对接连接，输出主管道8-4的端部与主风机8-8的入口对接连接，主风机8-8的出口与烟囱8-9连接。在主风机8-8的作用下，输入主管道8-5内的气流向下进入各活性炭吸附箱8-6内，经吸附净化作用之后从底部排出并进入输出主管道8-4，最终从烟囱8-9排放至大气。
本实施例中，脱附净化装置8还包括一个分支组件，用于在进行活性炭吸附箱8-6的维保工作时保持小流量的气流流通。分支组件包括分支管道8-7，分支管道8-7的尺寸小于输入主管道8-5和输出主管道8-4的尺寸。分支管道8-7的一端同时连接至各活性炭吸附箱8-6的顶部入口、另一端连接至烟囱8-9，在分支管道8-7的中部设有分支风机8-2，当需要对各活性炭吸附箱8-6进行维保工作时，关闭各活性炭吸附箱8-6顶部入口处的阀门，开启主风机8-8和分支风机8-2并且令两者以较小功率运转，则输入主管道8-5内的气流进入分支管道8-7，之后进入烟囱8-9，各活性炭吸附箱8-6内的气流经输出主管道8-4进入烟囱8-9，因而能够有效避免污染气体外溢，提升***运转的安全性。
还包括通过波纹软管道与输入主管道8-5连接的连接扩口8-1，连接扩口8-1安装固定在集气罩箱7的出气窗口上。采用波纹软管道连接的优点是令集气罩箱7具备前后移动的余量，在集气罩箱7作前后位置移动时，保证集气罩箱7与脱附净化装置8之间的可靠气路连接。
本实施例中，在集气罩箱7的内壁两侧安装有罩箱轨道7-1，在支撑框架10的前部两侧安装有与罩箱轨道7-1配合的支架轨道10-1，在支撑框架10的前部还安装有推拉油缸14，推拉油缸14的活塞杆前端与集气罩箱7的后部固定连接，推拉油缸14为长油缸，保证集气罩箱7的行程。通过控制推拉油缸14活塞杆的伸缩动作，实现对集气罩箱7的前后移动控制，罩箱轨道7-1与支架轨道10-1配合能够提升集气罩箱7移动时的稳定性。
工作过程：
从污染场地开挖得到的污染土壤采用工程车辆转运至专用堆放及处理场地进行堆放，通过初步晾晒降低污染土壤的含水率，本修复***设置在专用堆放及处理场地内；采用铲车等机具将堆放的污染土壤转移到提升装置1内，提升装置1连续地、分散地将污染土壤转移到铺展装置2上，铺展装置2将污染土壤向输送装置5上转移，在此过程中大颗粒的污染土壤向后方滚落，滚落至剪切振动装置9时受到剪切破碎作用，定期将接收板9-1上的污染土壤采用铲斗等转移到料斗1-1内；
输送装置5上向前提升输送的污染土壤经过摊铺装置3时受到摊铺作用，堆积较厚位置的污染土壤被进一步摊铺开来，形成较薄的土壤层；经过喷洒装置4时，修复药剂以雾化的方式喷淋到污染土壤层上，值得注意的是，此处的修复药剂以雾化喷淋的方式喷淋到土壤层上，并不会导致土壤潮湿结块，喷洒修复药剂后的污染土壤，其内部的污染物成分与修复药剂发生反应，污染物的浓度降低到可接受的水平，或将有毒有害的污染物转化为无害的物质；
喷洒了修复药剂的土壤越过输送装置5的上端并下落进入下料漏斗17内，在下落过程中通过过滤篦子18；之后污染土壤从下料漏斗17的底部出口排出并落入下方的土筐16内，污染土壤在土筐16内以相对松散的状态堆积，土筐16内接收了半筐或者多半筐土壤后需要向后方进行转移；
人工采用叉车机具将空置的土筐16从A型支座15侧部的窗口置入内部，推送油缸12动作，将该土筐16向前顶动一个工位，该土筐16将前方的那个已经接收了污染土壤的土筐16向前顶动一个工位即转移到升降架装置6后方底部的那个升降组件的托板6-4上，之后驱动电机6-2动作令升降组件移动一个工位，则后方的各升降组件上升一个工位、前方的各升降组件下降一个工位，前述土筐16上升，下一个空置的升降组件移动到装载位置，之后人工采用叉车机具将下一个空置的土筐16从A型支座15侧部的窗口置入内部，推送油缸12动作，将该土筐16向前顶动一个工位，第二个装入了污染土壤的土筐16转移到升降架装置6上，如此重复，直至升降架装置6上装载了多个装入了土壤的土筐16，此时提升装置1以及驱动电机11、喷洒装置4暂停运转；
之后推拉油缸14动作，令集气罩箱7向后移动，令升降架装置6完全落入集气罩箱7内，脱附净化装置8一直处于连续运转状态，集气罩箱7内保持负压脱附环境，加速各土筐16内污染土壤中挥发物成分的脱附，脱附产生的污染气体向后进入脱附净化装置8，被各活性炭吸附箱8-6作吸附净化处理，尾气从烟囱8-9排出至大气；
一定工艺时间之后推拉油缸14动作，集气罩箱7向前移动令升降架装置6完全从集气罩箱7转移出来，此时人工采用叉车等机具从升降架装置6的前方卸载转移土筐16至倾倒场所，具体地，每次卸载操作均发生在前方底部的那个升降组件上，每完成一个卸载，升降架装置6移动一个工位，直至完成全部土筐16的卸载、转移和倾倒作业；之后人工采用叉车等机具将空置的土筐16转移至A型支座15的侧方位，再次启动提升装置1、驱动电机11和喷洒装置4，将土筐16逐个置入内部并接收土壤，重复前述操作过程。
