用于烹饪应用的沼气压缩和存储系统在Rural Households

Abstract-

印度奥里萨邦奥里萨邦工程学院布巴内斯瓦尔（Bhubaneswar）进行了一个项目，以设计和开发沼气生产，纯化，压缩和存储系统，适合在农村家庭中用作烹饪气体。沼气是通过厨房废物的厌氧消化物在浮动鼓型消化器中生产的，并由弹性气球收集。设计了脚杆压缩机，它允许用户使用脚杆和阀门系统站立和压缩。最终原型能够在0.5m3储罐中压缩沼气为大约4bar。除压缩机外，还使用带有硅胶的容器从沼气中去除水蒸气，还有一个带有钢羊毛的纤维容器，用作硫化物硫化物洗涤塔，并带有沼气入口到压缩系统。结果表明，该系统可以将沼气压缩到容器中，4条压力和30分钟的工作时间。

Introduction

Biogas is becoming an increasingly important source of energy for rural areas in developing countries due to readily available organic wastes like kitchen wastes. Biogas has advantage in terms of low cost sustainable energy. Biogas is an appropriate alternative to the traditional solid and gaseous cooking fuels used by developing rural communities. Biogas digester is used to collect kitchen wastes and convert it to biogas through anaerobic digestion processes. Biogas is a clean-burning, renewable fuel that contains 50-60% methane and can be used in household cooking applications . Without an appropriate method of compression, the gas remains of a large volume and it is difficult for transport and storage.
The aim of the project is to design a system to compress and store the biogas in such a way that it will be suitable for cooking gas in rural communities. For compression of biogas we have designed a piston cylinder system i.e a modified bicycle pump which is the best compression method due to its low cost and can reach the required pressure within a short time. We have taken an air tank which is the suitable storage container for biogas.

Need of compression and storage of Biogas
农村家庭提供大量厨房废物。但是，没有努力将这些废物用于生产能源的目的。在生物消化商的帮助下，努力将这种沼气用作烹饪的来源。由于植物的尺寸较小和处理不当，因此气体的输出有限且不规则。它一直被视为另类安排的立场。因此，已提出压缩和存储系统使用消化器的沼气。沼气被纯化，压缩和储存在LPG圆柱体中，这使其易于运输。

Compression mechanism
The design is established as inclined “foot pump” mechanism using bicycle pumps

Foot compressor
我们的项目旨在在压力容器中的高压气体存储系统将压缩气体作为低成本能源存储。脚压缩机是用于便携式服务的，与常见的往复式压缩机类型不同。该压缩机的单级容量最小，可输送0.015m3/min，并且输送压力高达4 bar。

工作原则
脚压缩机设计包括两个汽缸that are supported to stand by a simple frame, based on foot-operated design (Fig.5). With this design, the container is kept stationary, which is stable and the cylinders move with the lever. The lever arm acts to give mechanical advantage and moves the two plungers through the body of the cylinders. The two cylinders are used with on-off valves to compress the biogas alternately. The valve system connects the two cylinders and allows for the variable operation of the system. The cylinders are connected in parallel, and each has two valves. One of these valves controls flow from the storage balloon, the other controls the flow of biogas to the inlet of the storage tank. Once the tank contains enough compressed gas, compression will become difficult and some of the cylinders can be disengaged in order to make pumping easier. In order to disengage a cylinder the biogas valve should be placed in the “off” position so that biogas is not pulled into that branch of the system.

Conclusion
我们的研究工作证明，沼气的生产，压缩和存储系统是可提供大量厨房废物的农村家庭的盈利企业。事实证明，沼气可以被压缩，存储在液化石油气缸中并使其可运输。为了制造适合烹饪涂料的沼气，纯化后最多可压缩4条棒，并填充液化石油气缸。除了能源生产外，沼气工厂还提供有机肥料，并有助于解决废物处理和无污染环境的问题。我们确定最可行的压缩方法是自行车泵。我们还确定，标准空气箱是此应用程序的理想选择，因为它易于使用，便宜，可容纳标准配件，并抵抗沼气的腐蚀。我们的最终设计是使用非常简单和常规的施工过程制造的。它是在2到3天的短时间内构建的。同样，我们的最终原型的成本约为3卢比/ 000/没有沼气消化池时。
