Description

一种陷阱式淤泥原位处理装置与方法 技术领域
本发明涉及环保设备技术领域，尤其涉及一种陷阱式淤泥原位处理装置与方法。
背景技术
随着生活水平的不断提高和人们环保意识的逐渐增强，人们对周边生活环境和生存空间质量都非常关注。面对日益恶化的各种环境，改善和治理的呼声越来越高。其中水体环境的保护和治污尤显突出。城市及其周围地区各种水体环境(包括水库、湖泊、河道、沟渠等)由于治理难度大，多年未治理使得大量淤泥沉积于水底，严重影响水体环境，使得水质变黑发臭，扰民问题时有发生。水体清淤是将河道、湖泊等的淤泥从水底切削、收集、抽取、输送至特定的地区集中进行环保处理的全过程。城市淤泥中生活垃圾、建筑垃圾堆积成山，湖底蕴藏大量的沼气、毒气、臭气甚至带有重金属等有害污染物质。如何进行环保清淤、清出的淤泥如何处理是当今国际社会都在探讨的问题。如果某个环节处理不好，清淤工程将带来严重的、大面积的二次污染，后果不堪设想。
淤泥中的污染物主要分布在底泥浅层0～20厘米的区域的浮泥以及流泥中，上部呈浆状(浮泥)，下部呈流塑状(流泥)，有臭味，一般呈黑色或灰黑色，地质沉积年代较新，有机质沉积速度快，为近几十年人类活动(富营养化或围隔养殖)对水环境影响的产物。此部分淤泥呈现推移质特征，极易在风浪、风吹流等综合动力因素作用下被掀起，并在风力助推作用下，向下风向聚集。淤泥的污染层在水体中稍微被搅动就能再悬浮，是水体内源污染物的主要蓄积库和释放源。推移质淤泥的清理，能够很直观的把污染水体的营养盐和重金属带出水体。
现有的底泥清淤技术主要有水利冲刷+泵吸、挖泥+吹填/船运、搅吸等技术，上述技术在实施过程中不但存在搅动底泥，加速淤泥中的营养盐向水体中释放的危害，清出的淤泥需要脱水、堆放和填埋还占用土地资源，易造成二次污染，甚至在乏科学认知和深入调研的情况下，把底泥挖出来清理掉，打破原有湖床河道水生态系统。针对上述弊端，有提出采用在需要底泥清淤出开挖一定数量及深度的淤泥捕获沟渠，通过自然水动力带动的浮泥、流泥经过沟渠时跌落到沟渠底部，此法虽然减少了清淤过程中底泥扰动的程度，但淤泥填满清出时仍面临脱水、堆放和填埋等问题，鉴于上述技术的各种缺陷，有必要对现有清淤技术中使用的装备进行改进，以实现原位的处理，降低淤泥处置过程中产生的次生危害。
发明内容
为了解决上述问题，本发明的第一目的在于提供一种陷阱式淤泥原位处理装置，该方案在原位上对于淤泥进行干化、脱水处理，降低了清出的淤泥对于环境的二次污染；并且该方案可利用湖流等自然因素将淤泥集中在陷阱管内部隔水处理，对底栖生境扰动小，影响范围小，对水底生态破坏小。
本发明的第二目的在于提供一种陷阱式淤泥原位处理方法，该陷阱式淤泥原位处理方法采用上述原位处理装置。
为了实现上述的目的，本发明采用了以下的技术方案：
一种陷阱式淤泥原位处理装置，其特征在于：包括陷阱管、挡水管和加热装置；
所述陷阱管用于置入湖床或河床内，陷阱管内部构成用于存放淤泥的陷阱腔；
所述挡水管的上端高于水面，且下端与陷阱管上端对接，用以阻挡河(湖)水进入陷阱腔；
所述加热装置对于陷阱管陷阱腔内的淤泥进行加热干化。
本发明采用上述技术方案，该技术方案涉及一种陷阱式淤泥原位处理装置，该淤泥原位处理装置包括陷阱管、挡水管和加热装置。其中，陷阱管用于置入湖床或河床内，通过人工或水体流动的作用使淤泥能够流入陷阱腔；如此，陷阱管将陷阱腔内的淤泥与管外的淤泥分隔开。挡水管则是能够阻挡河水进入陷阱腔，即采用管内的河水与管外的河水隔开；如此才能将挡水管内部河水抽干。加热装置对于陷阱管陷阱腔内的淤泥进行加热干化，淤泥水汽不断蒸发，逐渐干化。
与现有淤泥清理相比，该方案在原位上对于淤泥进行干化、脱水处理，降低了清出的淤泥对于环境的二次污染；并且该方案可利用湖流等自然因素将淤泥集中在陷阱管内部隔水处理，对底栖生境扰动小，影响范围小，对水底生态破坏小。
作为优选，所述加热装置包括能够钻入地底获取地热能的导热管，以及处于陷阱管陷阱腔内部并与所述导热管之间产生热传导的导热部件。该技术方案中进一步限定了加热装置的具体结构，该加热装置通过导热管钻入地底获取地热能并将地热能传导出来，即利用地热能对收纳的淤泥进行烘干，无需消耗能源。并且，该方案相比于其他加热方式，也减少污染和使用安全隐患，且不受条件的限制。
作为优选，所述导热部件设置在陷阱管的内侧壁或形成在陷阱管内部，导热管与导热部件相导通实现热传导。在上述技术方案记载利用地热能对收纳的淤泥进行烘干的原理上，本方案进一步限定了导热部件的围绕在陷阱管的内侧壁设置或形成在陷阱管内部，导热管将热量传递到导热部件上时，导热部件能以围合内部淤泥的方式从外至内对于淤泥加热干化，外围的淤泥与导热部件更近，更易于受热干化；内部的淤泥则受到周向多个方位的导热，故也 相对易于干化，如此保证各区域的淤泥加热均匀。
作为优选，所述导热部件内设有导热腔或者是导热部件与陷阱管之间构成导热腔；所述导热管和导热部件内的导热腔中设有相互导通的导热流体介质。在该技术方案中，导热管获取地热后是通过导热流体介质将热量传递至导热部件内的导热腔中，热传导效率更高。
作为优选，所述陷阱管包括底板以及围绕底板边缘设置的侧壁；所述侧壁和底板之间构成陷阱腔，导热管穿过所述陷阱管的底板。如上述技术方案所述，陷阱管将陷阱腔内的淤泥与管外的淤泥分隔开，故对于陷阱管来说其围合设置的侧壁是必须的，底板并非必须。在另一实施方案中，陷阱管可以不设置底板；但相比之下，该方案在陷阱管的底部设置底板，能够提升干化效率，减少干化所耗时间。
作为优选，所述导热部件为设置在陷阱管内侧的内管体；内管体与陷阱管之间构成导热腔；所述导热管至少包括处于陷阱管下方的下部管段，以及处于陷阱管上方的上部管段；所述下部管段的上端与陷阱管的底板相连接，上部管段的上端高于水面，下端与所述内管体或陷阱管相通；所述上部管段、下部管段和导热腔相导通。在上述方案记载导热管通过导热流体介质将热量传递至导热部件的方案基础上，该方案进一步限定了导热部件、陷阱管和导热管的连接结构。具体来说，该方案中的导热部件为内管体，内管体与陷阱管之间构成了内外管的形式且内部构成导热腔，类似导热夹层；而该导热腔上设有两个开口，一开口与下部管段相通，另一开口与上部管段相通，如此导热腔、下部管段和上部管段全部相通，导热流体介质能够在导热腔、下部管段和上部管段之间流通。当插入地底端在地热的作用下将导热管内的导热流体介质加热，底部介质升温后比重较上部介质比重轻而形成上下对流，导热流体介质经导热管流入导热腔内，通过导热部件对陷阱管内的淤泥加热。
作为优选，还包括相对所述陷阱管径向布置的若干条导泥槽，导泥槽的近端深度大于远端深度且近端指向陷阱腔。该技术方案还设置导泥槽，通过导泥槽的设置，使远离陷阱式淤泥原位处理装置的淤泥在湖流的作用下流进导泥槽，再从导泥槽进入陷阱管内，实现淤泥的自然收集。
作为优选，所述挡水管的下端套接于陷阱管的外端部上。挡水管直接置于陷阱管上端的方案是需要对连接处进行密封，而本方案中的挡水管比陷阱管略大，套在陷阱管外直接插在湖床中则可达到密封效果，不需要另外密封。
一种陷阱式淤泥原位处理方法，其特征在于：包括如下步骤：
S1：将陷阱管置入湖床或河床内，淤泥自然或人为流入陷阱管中，直至装满不再沉降为止；
S2：将挡水管罩住陷阱管，抽干陷阱管上覆水；
S3：采用加热装置对陷阱管内的淤泥进行加热，同时，淤泥自然发生厌氧消化作用并产生热 量，在自然沉降、地热和生化热叠加作用下淤泥水汽不断蒸发，逐渐干化并持续沉降减容，直至含水率低于预设标准；
S4：用隔水材料盖住陷阱管内的淤泥上，拔出挡水管；
S5：重复S1-S4步骤，直至陷阱内装满含水率低于预设标准的淤泥时，执行S6；
S6：先从位于陷阱管底部淤泥含水率最低的部分开始，用泵或适当方式清除陷阱管内淤泥，拔出挡水管。
作为优选，所述步骤S1包括布置导泥槽或挖取沿陷阱管径向布置导泥槽；由于淤泥存在流动性，靠近陷阱式淤泥原位处理装置陷阱口的淤泥在湖流的作用下直接流入到陷阱管内，远离陷阱式淤泥原位处理装置的淤泥在湖流的作用下流进导泥槽，再从导泥槽进入陷阱管内，实现淤泥的自然收集。
作为优选，加热装置包括能够钻入地底获取地热能的导热管，以及处于陷阱管陷阱腔内部并与所述导热管之间产生热传导的导热部件，导热管和导热部件内的导热腔中设有相互导通的导热流体介质；步骤S3具体是：在导热管中注入导热流体介质，导热管内部的导热流体介质吸收地下热量，并流动至导热管上部及导热部件中，对陷阱管内的淤泥进行加热。
综上所述，本发明与现有技术相比的有益效果是：

实施例1：
如图1和2所示，本实施例涉及一种陷阱式淤泥原位处理装置，包括陷阱管2、挡水管1 和加热装置。陷阱管2、挡水管1和加热装置的具体结构如下：
所述陷阱管2用于置入湖床7或河床内，陷阱管2内部构成用于存放淤泥的陷阱腔。具体来说，所述陷阱管2包括底板以及围绕底板边缘设置的侧壁，所述侧壁和底板之间构成陷阱腔。此方案中的陷阱管2用于置入湖床7或河床内，通过人工或水体流动的作用使淤泥5能够流入陷阱腔。陷阱管2需将陷阱腔内的淤泥与管外的淤泥分隔开，对于陷阱管2来说其围合设置的侧壁是必须的，底板并非必须。在另一实施方案中，陷阱管2可以不设置底板。但相比之下，该方案在陷阱管2的底部设置底板，能够提升干化效率，减少干化所耗时间。在实际使用时，陷阱管直径大于10cm，上端与湖床齐平，下端深度不超过100米。
所述挡水管1的上端高于水面8，且下端与陷阱管2上端对接，用以阻挡河水进入陷阱腔；即使管内的河水与管外的河水隔开。在进一步的实施方案中，所述挡水管1的下端套接于陷阱管2的外端部上。挡水管1直接置于陷阱管2上端的方案是需要对连接处进行密封，而本方案中的挡水管1比陷阱管2略大，套在陷阱管2外直接插在湖床7中则可达到密封效果，不需要另外密封。
所述加热装置对于陷阱管2的陷阱腔内的淤泥进行加热干化。使用时一般在抽干挡水管1内部河水后，才使用加热装置对于陷阱管2的陷阱腔内的淤泥进行加热，使淤泥水汽10不断蒸发，逐渐干化。上述的加热装置可以是任意一种能够伸入陷阱管2的陷阱腔内，以对于淤泥进行加热的装置；如可以是电加热管，由挡水管1的顶部伸入陷阱管2的陷阱腔内。
在本实施例记载的更优选的方案中，所述加热装置包括能够钻入地底获取地热能的导热管3，以及处于陷阱管2陷阱腔内部并与所述导热管3之间产生热传导的导热部件11，导热管3穿过所述陷阱管2的底板，所述的导热管3上端高于湖床，下端深度超过100米。该技术方案中进一步限定了加热装置的具体结构，该加热装置通过导热管3钻入地底获取地热能并将地热能传导出来，即利用地热能对收纳的淤泥进行烘干，无需消耗额外的能源。并且，该方案相比于其他加热方式，也减少污染和使用安全隐患，并不受条件的限制。在进一步的实施方案中，所述导热部件11设置在陷阱管2的内侧壁或形成在陷阱管2内部，导热管3与导热部件11相导通实现热传导。上述技术方案记载利用地热能对收纳的淤泥进行烘干的原理上，本方案进一步限定了导热部件11的围绕在陷阱管2的内侧壁设置或形成在陷阱管2内部，导热管3将热量9传递到导热部件11上时，导热部件11能以围合内部淤泥的方式从外至内对于淤泥加热干化，外围的淤泥与导热部件11更近，更易于受热干化。内部的淤泥则受到周向多个方位的导热，故也相对易于干化，如此保证各区域的淤泥加热均匀。
基于上述方案，本方案中的导热部件11内设有导热腔或者是导热部件11与陷阱管2之间构成导热腔12。所述导热管3和导热部件11内的导热腔12中设有相互导通的导热流体介 质4，此处的导热流体介质4一般选用水。导热管3获取地热后是通过导热流体介质4将热量9传递至导热部件11内的导热腔12中，热传导效率更高。导热部件11、陷阱管2和导热管3的连接结构如下：所述导热部件11为设置在陷阱管2内侧的内管体，内管体与陷阱管2之间构成导热腔12。所述导热管3至少包括处于陷阱管2下方的下部管段31，以及处于陷阱管2上方的上部管段32。所述下部管段31的上端与陷阱管2的底板相连接，由于下部管段31需要获得地热能，可能需要钻入几百米的地底，故下部管段31可采用是多根管体拼接构成。上部管段32的上端高于水面8，下端与所述内管体或陷阱管2相通。所述上部管段32、下部管段31和导热腔12相导通。在上述方案记载导热管3通过导热流体介质4将热量9传递至导热部件11的方案基础上，该方案中的导热部件11为内管体，内管体与陷阱管2之间构成了内外管的形式且内部构成导热腔12，类似导热夹层。而该导热腔12上设有两个开口，一开口与下部管段31相通，另一开口与上部管段32相通，如此导热腔12、下部管段31和上部管段32全部相通，导热流体介质4能够在导热腔12、下部管段31和上部管段32之间流通。当插入地底端在地热的作用下将导热管3内的导热流体介质4加热，当底部介质升温后比重较上部介质比重轻而形成上下对流，导热流体介质4经导热管3流入导热腔12内，通过导热部件11对陷阱管2内的淤泥加热。
最后，上述陷阱式淤泥原位处理装置还包括相对所述陷阱管2径向布置的若干条导泥槽6，导泥槽6的近端深度大于远端深度且近端指向陷阱腔。该技术方案还设置导泥槽6，通过导泥槽6的设置，使远离陷阱式淤泥原位处理装置的淤泥在湖流的作用下流进导泥槽6，再从导泥槽6进入陷阱管2内，实现淤泥的自然收集。此方案中的导泥槽6作为陷阱式淤泥原位处理装置，是一种沟槽构件，为装置的一组成部分。当然导泥槽6也可以是临时在河床上开挖的沟渠，此时导泥槽6就不作为陷阱式淤泥原位处理装置的组成部分。
综上所述，本发明与现有技术相比的有益效果是：
通过本发明所示出的陷阱式淤泥原位处理装置及方法，可利用湖流等自然因素收集淤泥与现有淤泥清理相比，不需要消耗能源，且在淤泥收集过程中对底栖生境扰动小，影响范围小，对水底生态破坏小。
通过本发明所示出的陷阱式淤泥原位处理装置及方法，利用地热能对收纳的淤泥进行烘干，无需消耗能源。
通过本发明所示出的陷阱式淤泥原位处理装置及方法，利用地热对污泥进行干化，无需添加絮凝等药剂，避免了使用化学药剂后淤泥无法利用的。
最后，本申请所示出的陷阱式淤泥原位处理装置及方法，实现了对水底污染最为严重的流动态淤泥实现了连续性的处理，有利于富营养化水体的内源治理。
上述实施例记载的陷阱式淤泥原位处理装置的具体淤泥处理方法，则参考实施例2。
实施例2：
如图3所示，本实施例记载一种陷阱式淤泥原位处理方法，该处理方法采用上述实施例1中的陷阱式淤泥原位处理装置，具体包括如下步骤：
S1：将陷阱管2置入湖床7或河床内，淤泥自然或人为流入陷阱管2中，直至装满不再沉降为止。具体来说，该步骤还布置导泥槽6或挖取沿陷阱管2径向布置导泥槽6；由于淤泥存在流动性，靠近陷阱式淤泥原位处理装置陷阱口的淤泥在湖流的作用下直接流入到陷阱管2内，远离陷阱式淤泥原位处理装置的淤泥在湖流的作用下流进导泥槽6，再从导泥槽6进入陷阱管2内，实现淤泥的自然收集。
S2：将挡水管1罩住陷阱管2，抽干陷阱管2上覆水。
S3：采用加热装置对陷阱管2内的淤泥进行加热，具体是在导热管3中注入水，导热管3内部的水吸收地下热量9，并流动至导热管3上部及导热部件11中，对陷阱管2内的淤泥进行加热。同时，淤泥自然发生厌氧消化作用并产生热量9，在自然沉降、地热和生化热叠加作用下淤泥水汽10不断蒸发，逐渐干化并持续沉降减容，直至含水率低于预设标准。
S4：用隔水材料盖住陷阱管2内的淤泥上，拔出挡水管1。
S5：重复S1-S4步骤，直至陷阱内装满含水率低于预设标准的淤泥时，执行S6。
S6：先从位于陷阱管底部淤泥含水率最低的部分开始，用泵或适当方式清除陷阱管2内整管淤泥，拔出挡水管1。
以下是对于附图3中框图含义进行说明，其中
收集代表将淤泥自然或人为流入陷阱管2中，即指步骤S1；
挡水代表将挡水管1罩住陷阱管2，阻挡河水进入陷阱腔；即指步骤S2；
干化代表加热装置对陷阱管2内的淤泥进行加热干化，记载在S3中；
消化代表进入陷阱管2中的淤泥在自然条件下的厌氧消化淤泥中的有机质，记载在S3中；
封存代表用隔水材料盖住陷阱管2内的淤泥上，即指S4；
清除代表将陷阱管2内整管淤泥清掉，即指步骤S6；
小循环是指重复步骤S1-S4；大循环是指重复步骤S1-S6。
实验记录：
申请人采用实施例1中记载的陷阱式淤泥原位处理装置和实施例2中记载的一种陷阱式淤泥原位处理方法，通过多次实验得到以下数据；当导热管3下端端插入地底500米深度， 陷阱管2内的温度能够达到30℃以上；当导热管3下端端插入地底700米深度，陷阱管2内的温度还能提升6℃左右。虽然两组数据中，导热管插入地底的深度不同，但陷阱管2内的淤泥被干化至含水率都能能低于75％，不过导热管3插入地底700米的方案相比于插入地底500米的方案，干化效率更高，所花费时间更短。从其实验可以看出导热管3所能获得的能量与陷阱管2内的淤泥被干化程度有关；在干化时间足够的情况下，上述装置和方法可使淤泥被干化的含水率是可以低于60％。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管上面已经示出和描述了本发明的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本发明的限制，本领域的普通技术人员在不脱离本发明的原理和宗旨的情况下在本发明的范围内可以对上述实施例进行变化、修改、替换和变型。
