Description

自动加压回流沼气池
技术领域
本实用新型涉及一种沼气池，它除了可采用人或动物排泄物制沼外，尤其突出体现在利用免经切碎的秸秆类、藤条类，如：稻草、香蕉、花生、甘薯等的发酵制沼设备。
背景技术
目前在我国农村推广的沼气池是采用圆筒形水压沼气型的结构，以国家标准的M3圆筒型水压沼气池为例，其池型的结构特点是1、主池属于圆形，相对于其他形状(如椭圆、方体)其容量大，墙壁受力均匀，池体相对牢固，进料后布料均匀，发酵较充分；2、采用水压式，其主池上部贮气室完全封闭，出料间(俗称副池)既是出料处又是水压间。随着沼气的不断产生，主池间液面随之升高。当用气时，沼气减少，水压间的料液又返回池内。这样，部分料液的来回串动，引起水压的反复变化，达到贮存和排放沼气的目的。
以上沼气池的主要优点是1、能充分利用土壤的承载能力，池体受力性良好；2、适于装填多种发酵原料(猪粪便、作物桔杆等)；3、便于经常进料，猪舍、厕所粪便随时都能打扫进池；4、池体周围都与土壤接触，对池体保温有一定作用。但是存在以下缺点：1、由于气压反复变化，对池体强度和使用沼气的灯具、灶具燃烧效率的稳定与提高都有不利的影响；2、由于没有搅拌装置，池内浮渣容易结壳，又难于破碎，所以发酵原料的利用率不高，池容产气率偏低(每天仅为0.15M3/M3左右)；3、由于只有一个发酵池，当进料较频繁，进料量较大时，会使一些原料不经发酵就溢出，不能充分发酵。
发明内容
本实用新型的目的在于针对已有圆筒型水压式沼气池存在的缺点，提供一种适合于秸秆类发酵制沼，瓢舀渣液方便，料利用率高，能充分发酵，产气率高，供气均匀稳定，有利于保护池体，能有效解决浮渣结壳，残渣沉积问题，使用寿命较长的水压式自动加压回流排渣沼气池。
本实用新型设有发酵间和水压间，水压间与发酵间底部相通，又处于发酵间顶部，发酵间顶部的水压间两侧分别设回流口和强回流口，回流口与出料间相通，强回流口与进料间相通，略低于溢流口。当沼气池发酵，池内气压加大，迫使处于顶部水压间的料液流入进料口，达到循环利用的目的。发酵池上部的贮气室设出气口，出气口接导气管。在发酵池的顶部设池盖，在发酵池上部贮气室的出气口设阀门，在发酵池内底部设弧形旋流布料墙，且池底倾斜度为3°～5°。
与已有的沼气池相比，本实用新型的优点是：1)原料利用率提高，发酵更加充分。因原料在池中滞留时间延长，发酵面积增加，发酵更加充分，使原料发酵更加彻底。2)起到破壳作用，由于增设旋流布料墙，进料后料液能自动翻滚，充分搅拌，能及时破坏结壳层，同时及时将一些固体残渣带出去，避免残渣淤积，有效解决浮渣结壳、残渣沉积问题，延长沼气池使用寿命。3)自动强回流，水中包气，其优点是，产气量高且稳定，易查出是否漏气，提高使用安全性。4)增设排渣管，采用机械抽压式抽取渣液，比以前用人工飘舀渣液，省事方便。5)便于大量进料，适合于秸秆类发酵制沼。

图2为本实用新型实施例的剖面结构示意图。
具体实施方式
如图1、图2所示，本实用新型设有发酵池1，池内建一堵弧形旋流布料墙2，水压间3与发酵池下半部连通，发酵池为圆筒形，在发酵池1和水压间3一侧设进料口4，且进料口4处于旋流布料墙一侧，在发酵池1与水压间3另一侧设排渣口5，在发酵池一侧设有自动强回流口6，发酵池上部的贮气室8设导气管7，在发酵池上方设一检查口9，在与强回流口6对应的一侧设有溢流口10，在发酵池和水压间设有回流口11，发酵间13与水压间联通口12处于发酵池底部。
