沼氣發動機發電機組系統的組成

(1)沼氣脫硫及穩壓、防爆裝置:沼氣中含有少量的h2s,該氣體對發動機有強烈的腐蝕作用,因此供發動機使用的沼氣要先經過脫硫裝置。

(1) biogas desulfurization and stable pressure and explosion-proof device: biogas contains a small amount of H2S, which has a strong corrosive effect on the engine, so the biogas used for the engine must go through the desulfurization device first.

D88尊龙沼氣作為燃氣,其流量調節是基于壓力差,為了使調節準確,應確保進入發動機時的壓力穩定,故需要在沼氣進氣管路上安裝穩壓裝置。另外,為了防止進氣管回火引起沼氣管路發生爆炸,應在沼氣供應管路上安置防回火與防爆裝置。

D88尊龙Biogas as gas, its flow regulation is based on pressure difference. In order to make the regulation accurate, we should ensure that the pressure is stable when entering the engine, so we need to install a voltage stabilizing device on the biogas intake pipeline. In addition, in order to prevent the intake pipe backfire caused by the explosion of the biogas pipeline, the fireproof and explosion-proof device should be placed on the supply line of the biogas supply.

(2)進氣系統:在進氣總管上,需加裝一套沼氣一空氣混合器,以調節空燃比和混合氣進氣量,混合器應調節精確、靈敏。

D88尊龙(2) intake system: on the intake manifold, a biogas air mixer shall be installed to regulate the air-fuel ratio and the intake volume of the mixture. The mixer should be adjusted accurately and sensitively.

(3)發動機:沼氣的燃燒速度很慢,若發動機內的燃燒過程組織不利,會影響發動機運行壽命,所以對沼氣發動機有較高的要求。

(3) engine: biogas burning rate is very slow. If the organization of combustion process is unfavorable, the operation life of engine will be affected, so the biogas engine has higher requirement.

4)調速系統:沼氣發動機的運行場合是和發電機一起以用電設備為負荷進行運轉,用電設備的裝載、卸載會使沼氣發動機負荷產生波動,為了確保發電機正常發電,沼氣發動機上的調速系統必不可少。

4) speed control system: operation situation of biogas engine and generator is in electrical equipment for load operation, the electric equipment loading and unloading will make the load fluctuation of biogas engine, in order to ensure the normal power generator, speed control system of biogas engine will not be less.

沼氣發酵的條件就是在工藝上滿足微生物的生存條件,使它們在合適的環境中生長、發育、繁殖、代謝。在發酵條件比較穩定的情況下,微生物生命活動越旺盛,產生的沼氣就越多,產氣時間就越長-相反,環境條件滿足不了微生物生命活動的需要,沼氣發酵就會停止,如原料干物質濃度過高時,產酸量增大,產氣就會受阻,甚至不產氣。

D88尊龙The condition of biogas fermentation is to meet the survival conditions of microbes and make them grow, develop, reproduce and metabolize in a suitable environment. Relatively stable in the fermentation conditions of microbial life activities more exuberant, the biogas produced more gas, more time - on the contrary, environmental conditions can not meet the needs of microbial life activities, biogas fermentation will stop, such as raw material dry matter concentration is too high, acid production increased, gas production will be blocked, or not gas production.

因此,人們在制取沼氣時,必須控制好沼氣發酵條件,給沼氣微生物創造一個良好的生活環境。

Therefore, when people make biogas, it is necessary to control the conditions of biogas fermentation and create a good living environment for biogas microbes.
