Description
技术领域
本实用新型涉及一种沼气池，尤其是采用人或动物排泄物和其他有机物制成沼气和肥料的设备。
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、能充气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，提供一种适合于大中型(人蓄、秸秆类)发酵制沼，瓢舀渣液方便，料利用率高，充分发酵，产气率高，供气均匀稳定，适合于远距离送气，有利于保护池体，能有效解决浮渣结壳，残渣沉积问题，使用寿命较长的隧道顶返式水压自动排渣沼气池。
本实用新型设有发酵池和水压间，发酵池和水压间串联连通，发酵池为隧道型，在发酵池和水压间一侧设进料口，在发酵池和水压间另一侧设溢流口和排渣口，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。
与已有的沼气池相比，本实用新型的优点是：1)采用隧道式，原料在池中滞留时间长，充分发酵，大大提高原料利用率。2)产气量高，大于40％，使用过程中气压均匀稳定，3)可适用于远距离输送(1-2公里)。4)水中包气，减少气压变化对池壁的冲击，延长发酵池的使用寿命。5)容易查出是否漏气，提高使用安全性。6)适用于大中型养殖场。

图2为本实用新型实施例的平面结构示意图。
具体实施方式
如图1、图2所示，本实用新型设有发酵池1、11，进料口2在发酵池的一侧，发酵池顶部设导气管3和4，发酵池顶部中央位置设一个检查天窗口5，砖墩6位于池顶中部，水压间7、10在发酵池进料口的对应一侧且与发酵池下半部连通，溢流口8开在水压间的上方，9为储气室。
