沼氣發(fā)電是集環(huán)保和節(jié)能于一體的能源綜合利用新技術(shù),它利用工業(yè)、農(nóng)業(yè)或城鎮(zhèn)生活中的大量有機(jī)廢棄物(例如:酒糟液、禽畜糞、城市垃圾和污水等)經(jīng)厭氧發(fā)酵處理產(chǎn)生的沼氣,驅(qū)動(dòng)沼氣發(fā)電機(jī)組發(fā)電,利用沼氣發(fā)電對(duì)氣體成分有的要求,氣體中的雜質(zhì)含量如Si、HS等應(yīng)控制在的范圍內(nèi),沼氣的溫度為10~60 ℃,壓力為 0~5kpa ,一般禽畜糞厭氧處理的沼氣都能滿足發(fā)電的氣質(zhì)要求,污水處理沼氣需要脫硫等處理,垃圾填埋沼氣需要脫水等處理。

Biogas power generation is a new energy comprehensive utilization technology that integrates environmental protection and energy conservation. It uses a large amount of organic waste (such as distiller's grains, poultry manure, urban garbage, and sewage) from industrial, agricultural, or urban life to produce biogas through anaerobic fermentation treatment, driving the biogas generator set to generate electricity. The use of biogas power generation requires certain gas composition requirements, and the impurity content in the gas, such as Si and HS, should be controlled within a certain range. The temperature of biogas is 10-60 ℃ and the pressure is 0-5kpa. Generally, anaerobic treatment of poultry manure biogas can meet the gas quality requirements for power generation. Wastewater treatment biogas requires desulfurization and other treatments, while landfill biogas requires dehydration and other treatments.

沼氣發(fā)電效率與氣體中的甲烷濃度有關(guān),理論上甲烷含量55%的沼氣每立方沼氣可發(fā)電1.8KWh,實(shí)際發(fā)電時(shí),沼氣濃度一般不能穩(wěn)定在一個(gè)固定值上,在這種情況下,沼氣發(fā)電機(jī)組照??梢赃\(yùn)行,只是發(fā)電量會(huì)有所降低,發(fā)出的電量可進(jìn)行上網(wǎng),沼氣發(fā)電機(jī)組的輸出電壓為400V,可以與6300V或10000V變壓器低壓端相聯(lián),若低壓線路長(zhǎng),400V可以升壓到6300V與*進(jìn)線相連。

The efficiency of biogas power generation is related to the methane concentration in the gas. In theory, biogas with a methane content of 55% can generate 1.8KWh of electricity per cubic meter of biogas. However, in actual power generation, the biogas concentration generally cannot be stable at a fixed value. In this case, the biogas generator set can still operate, but the power generation will be reduced, and the generated electricity can be connected to the grid. The output voltage of the biogas generator set is 400V, which can be connected to the low-voltage end of the 6300V or 10000V transformer. If the low-voltage line is long, 400V can be boosted to 6300V and connected to the * incoming line.

許多打算做沼氣發(fā)電的用戶經(jīng)常會(huì)問(wèn)的一個(gè)問(wèn)題就是,應(yīng)該選擇多大功率的發(fā)電機(jī)組合適,理論上甲烷含量55%的沼氣每立方沼氣可發(fā)電1.8KWh;一般沼氣池每天的產(chǎn)氣量是沼氣池體總?cè)莘e的20%左右(選用沼氣池工藝不同,產(chǎn)氣量不同),具體的就要計(jì)算才能確定了。算出每天的沼氣可發(fā)電的總量,然后再根據(jù)每天的發(fā)電時(shí)間,就可以確定發(fā)電機(jī)組的裝機(jī)功率。

A common question that many users who plan to use biogas for power generation often ask is what power generation unit is suitable. In theory, biogas with a methane content of 55% can generate 1.8KWh of electricity per cubic meter; The daily gas production of a typical biogas digester is about 20% of the total volume of the digester (the gas production varies depending on the process used), and the specific amount needs to be calculated to determine. Calculate the total amount of biogas that can generate electricity every day, and then determine the installed power of the generator set based on the daily power generation time.

例如:

For example:

每天沼氣總量500方,則發(fā)電總量:500×1.8=900度

If the total amount of biogas is 500 cubic meters per day, the total power generation is 500 × 1.8=900 kWh

若要24小時(shí)發(fā)電,則每小時(shí)發(fā)電量為900÷24=37.5

If 24-hour power generation is required, the hourly power generation will be 900 ÷ 24=37.5

國(guó)產(chǎn)沼氣發(fā)電機(jī)組一般以額定功率的80%運(yùn)行,則是實(shí)際裝機(jī)功率:37.5÷80%=46.87KW ,所以每天產(chǎn)氣500方的沼氣池,需要大于46.87KW的發(fā)電機(jī)組可以滿足要求。

Domestic biogas generator sets generally operate at 80% of the rated power, and the actual installed power is 37.5 ÷ 80%=46.87KW. Therefore, for a biogas digester with a daily gas production of 500 cubic meters, a generator set larger than 46.87KW is required to meet the requirements.

1、濾清器保養(yǎng):

1. Filter maintenance:

①空氣濾清器:每運(yùn)轉(zhuǎn)50小時(shí),以空壓機(jī)口吹氣清算一次。每運(yùn)轉(zhuǎn)500小時(shí)或當(dāng)警示安裝呈紅色時(shí)改換,改換濾芯后按頂端按鈕將指示重視定;

① Air filter: After every 50 hours of operation, blow air through the air compressor port to clean it. Replace the filter element every 500 hours of operation or when the warning installation turns red. After replacing the filter element, press the top button to indicate that it is important;

②機(jī)油濾清器:磨合期過(guò)后必需改換,以后每500小時(shí)或半年改換一次。改換濾清器后再開(kāi)機(jī)運(yùn)轉(zhuǎn)10分鐘,改換機(jī)油濾清器同時(shí)必需改換光滑油;

② Oil filter: It must be replaced after the running in period, and then every 500 hours or six months. After changing the filter, start the machine again and run for 10 minutes. When changing the oil filter, it is necessary to change the lubricating oil;

③柴油濾清器:磨合期過(guò)后必需改換,以后每500小時(shí)或半年改換一次。改換濾清器后再開(kāi)機(jī)運(yùn)轉(zhuǎn)10分鐘;

③ Diesel filter: It must be replaced after the running in period, and then every 500 hours or six months. After changing the filter, restart and run for 10 minutes;

④冷卻液濾清器:運(yùn)用200小時(shí)或三個(gè)月必需改換。以后每500小時(shí)或一年改換一次。

④ The coolant filter must be replaced after 200 hours or three months of use. Change every 500 hours or once a year in the future.
