养殖场用沼气发电机组需要哪些必备条件?

沼气工程作为畜禽废弃物资源化利用的能源环境工程,其沼气发电环节是较为常见的资源化利用模式,通过开展沼气发电利用,既能让养殖场提高自身的经济效益,又可缓解电力紧缺的矛盾,还能解决养殖场多余沼气利用等问题,是一举多得的好事情。
Biogas project is an energy and environmental project for the resource utilization of livestock and poultry wastes, and its biogas power generation link is a common resource utilization mode. Through the development of biogas power generation and utilization, it can not only improve the economic benefits of farms, but also alleviate the contradiction of power shortage, and solve the problems of surplus biogas utilization in farms, which is a good thing to achieve more with one stone.
养殖场开展沼气发电机组必须具备三大条件:其一有良好的沼气生产条件,其二有良好的沼气贮存条件,其三有良好的沼气发电利用设备(负荷)条件。
There are three conditions to develop biogas generating units in breeding farms: first, good biogas production conditions; second, good biogas storage conditions; third, good equipment (load) conditions for biogas power generation and utilization.
为了避免沼气池的产气量和生产发电及生活用气量不平衡,养殖场的沼气发电工程必须配备贮气柜。有了贮气柜,整个生产发电用气量的调蓄和稳压就有保证,纯沼气发电就有充分的可靠性、稳定性、安全性。因此设置沼气贮存设备是办好纯沼气发电不可缺少的稳定因素。
In order to avoid the imbalance of biogas production, power generation and domestic gas consumption, biogas power generation project of breeding farm must be equipped with gas storage tank. With the gas storage tank, the entire production of power generation gas storage and voltage regulation will be guaranteed, pure biogas power generation will have full reliability, stability and safety. Therefore, the installation of biogas storage equipment is an indispensable stable factor for running pure biogas power generation.

用电负荷量(或同时工作的用电设备功率)是养殖场选择(购买)沼气发电机组输出功率大小重要指标,也是沼气发电利用成功重要因素,直接关系到沼气发电的经济性、安全性和可靠性。
Electricity load (or the power of electric equipment working at the same time) is an important indicator of the output power of biogas generating units selected (purchased) by breeding farms. It is also an important factor for the success of biogas power generation and utilization, which is directly related to the economy, safety and reliability of Biogas power generation.
目前,养殖场利用沼气发电基本上是内部使用。在沼气气源稳定的条件下,假如无视沼气发电利用条件,没有按照养殖场的用电负荷来进行正确匹配沼气发电机组,则会出现下面情况:养殖场用电设备多、功率大,沼气发电机组输出功率小,那么大功率用电设备根本不能使用,沼气发电意义不大;反之,用电设备少、功率小,而采用发电功率大的发电机组,电机达不到一定负荷作功,从而造成发电机的耗能增加及热效率降低,节能效果不明显,费钱费气,经济效益突显不出。
At present, the use of biogas power generation is basically internal use. Under the condition of stable biogas source, if the utilization conditions of biogas power generation are ignored and the biogas generator set is not correctly matched according to the electric load of the breeding farm, the following situations will occur: there are many electric equipment and large power in the breeding farm, and the output power of the biogas generator set is small, then the high-power electric equipment can not be used at all, and the biogas power generation is of little significance; On the contrary, with less electrical equipment and small power, the generator set with high power generation can not reach a certain load, resulting in increased energy consumption and reduced thermal efficiency of the generator. The energy saving effect is not obvious, and the economic benefit is not obvious.
