沼气发电具有创效、节能、安全和环保等特点,是一种分布广泛且价廉的分布式能源. 市场研究表明沼气发电在发达国家已受到广泛重视和积极推广。

Biogas power generation has the characteristics of efficiency, energy conservation, safety, and environmental protection, and is a widely distributed and cost-effective distributed energy source Market research shows that biogas power generation has been widely valued and actively promoted in developed countries.

生物质能发电并网在西欧一些国家占能源总量的10%左右。 沼气发电技术是集环保和节能于一体的能源综合利用新技术。它是利用工业、农业或城镇生活中的大量有机废弃物(例如酒糟液、禽畜粪、城市垃圾和污水等),经厌氧发酵处理产生的沼气,驱动沼气发电机组发电,并可充分将发电机组的余热用于沼气生产。

Biomass energy grid connection accounts for about 10% of the total energy in some Western European countries. Biogas power generation technology is a new energy comprehensive utilization technology that integrates environmental protection and energy conservation. It utilizes a large amount of organic waste from industry, agriculture, or urban life (such as distiller's grains, livestock manure, urban garbage, and sewage), and produces biogas through anaerobic fermentation to drive the biogas generator set to generate electricity, and can fully utilize the waste heat of the generator set for biogas production.足球赌注

沼气发电热电联产项目的热效率,视发电设备的不同而有较大的区别,如使用燃气内燃机,其热效率为70%~75%之间,而如使用燃气透平和余热锅炉,在补燃的情况下,热效率可以达到90%以上。

The thermal efficiency of biogas cogeneration projects varies greatly depending on the type of power generation equipment used. For example, if a gas internal combustion engine is used, its thermal efficiency ranges from 70% to 75%. However, if a gas turbine and waste heat boiler are used, the thermal efficiency can reach over 90% with supplementary combustion.

沼气发电技术本身提供的是清洁能源,不仅解决了沼气工程中的环境问题、消耗了大量废弃物、保护了环境、减少了温室气体的排放,而且变废为宝,产生了大量的热能和电能,符合能源再循环利用的环保理念,同时也带来巨大的经济效益。

The biogas power generation technology itself provides clean energy, which not only solves environmental problems in biogas engineering, consumes a large amount of waste, protects the environment, and reduces greenhouse gas emissions, but also turns waste into treasure, generating a large amount of heat and electricity, in line with the environmental protection concept of energy recycling and utilization, and also brings huge economic benefits.

沼气发电机是通过垂直植入垃圾堆体里若干根抽气井,不间断将沼气抽出,经过收集管网送至发电机机组,再经过冷却脱硫脱水、过滤净化等处理后,产生的纯沼气在发电机组里燃烧后发电,再并入电网。

A biogas generator is a type of generator that continuously extracts biogas by vertically implanting several extraction wells into the garbage heap. The biogas is then collected through a collection pipeline and sent to the generator unit, where it is cooled, desulfurized, dehydrated, filtered, and purified. The resulting pure biogas is burned in the generator unit to generate electricity, which is then integrated into the power grid.

沼气发电原理: 首先就是要先从沼气讲起,沼气是部分有机物经过封闭式的厌氧发酵,发酵后就会含有部分沼气,然后经过收集。现在大部分都是生活垃圾或者污水COD含量高的企业沼气量比较充足。然后在开始说沼气的成分,沼气中的成分非常混杂,其中甲烷的含量是比较高的。而且甲烷是一种可燃性气体,热值也比较高。 收集后的沼气通过发电机组的发动机进行燃烧做工,就是内燃机形式,由做工后的扭矩带动发电机的转子绕组进行做工,完成发电流程。

The principle of biogas power generation: First of all, we need to start with biogas. biogas is a closed anaerobic fermentation of some organic matter, and after fermentation, it will contain some biogas, which is then collected. Nowadays, most enterprises with high COD content in household waste or sewage have sufficient biogas production. Then, when it comes to the composition of biogas, the components are very mixed, with methane content being relatively high. Moreover, methane is a combustible gas with a relatively high calorific value. The collected biogas is burned through the engine of the generator set, which is in the form of an internal combustion engine. The torque after the work drives the rotor winding of the generator to complete the power generation process.
