Description
技术领域technical field
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。The utility model relates to a methane pool, in particular to equipment for making methane and fertilizer by using human or animal excrement and other organic matters.
背景技术Background technique
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。At present, the biogas digesters promoted in rural areas of our country adopt a cylindrical hydraulic biogas structure. Taking the national standard M3 cylindrical hydraulic biogas digester as an example, the structural characteristics of the pool are: 1. The main pool is circular. Compared with other shapes (such as ellipse and square), it has a large capacity, the wall is evenly stressed, the pool body is relatively firm, the material is evenly distributed after feeding, and the fermentation is relatively sufficient; Closed, the discharge room (commonly known as the auxiliary tank) is both the discharge place and the hydraulic room. With the continuous production of biogas, the liquid level between the main pools will rise accordingly. When gas is used, the biogas is reduced, and the feed liquid in the hydraulic chamber returns to the pool. In this way, part of the feed liquid moves back and forth in series, causing repeated changes in water pressure to achieve the purpose of storing and discharging biogas.
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。The main advantages of the above biogas digesters are 1. It can be inflated to use the bearing capacity of the soil, and the pool body has good force resistance; 2. It is suitable for filling a variety of fermentation materials (pig manure, crop straw, etc.); 3. It is convenient for frequent feeding, Pig house and toilet feces can be cleaned into the pond at any time; 4. The surroundings of the pond body are in contact with the soil, which has a certain effect on the heat preservation of the pond body. However, there are the following disadvantages: 1. Due to repeated changes in air pressure, it has an adverse effect on the strength of the pool body and the stability and improvement of the combustion efficiency of lamps and stoves using biogas; It is difficult to break, so the utilization rate of fermentation raw materials is not high, and the gas production rate of the tank capacity is low (only about 0.15M3/M3 per day); 3. Since there is only one fermentation tank, when the feed is frequent and the feed volume is large , some raw materials will overflow without fermentation and cannot be fully fermented.
