1、首先對沼氣發(fā)電機(jī)房的位置作出規(guī)范，一般來說放在第1層或者是地下一層，同時(shí)要達(dá)到耐火的極限，不能夠低于兩個(gè)小時(shí)的隔墻。而且樓板與其他部位要隔開，要做好防泄漏的措施。

　　Firstly, the location of the biogas generator room should be standardized. Generally, it should be placed on the first floor or the basement, and it must meet the fire resistance limit, with a partition wall that cannot be breached for less than two hours. Moreover, the floor slab should be separated from other parts, and measures to prevent leakage should be taken.

　　2、沼氣發(fā)電機(jī)房要具備消防的設(shè)施，這里面就有水槍、消防栓，另外在機(jī)房內(nèi)部還需要配置干粉滅火器以及氣體的滅火器，同時(shí)要有顯著的標(biāo)語提醒人們。

　　2. The biogas generator room must be equipped with fire-fighting facilities, including water guns and fire hydrants. Additionally, dry powder fire extinguishers and gas fire extinguishers should be installed inside the room, and prominent signs should be provided to remind people.

　　3、這里面是不能夠有明火的，而且在機(jī)房內(nèi)還需要設(shè)置干燥的沙池，起到了消防的目的。要有照明的系統(tǒng)，還有獨(dú)立的抽風(fēng)系統(tǒng)以及火災(zāi)報(bào)警的裝置等等。

　　3. No open flames are allowed here, and a dry sandpit needs to be set up in the machine room for fire prevention purposes. There should be a lighting system, an independent ventilation system, a fire alarm device, and so on.

　　沼氣發(fā)電機(jī)機(jī)房的設(shè)置要求和選址注意事項(xiàng)

　　1、通風(fēng)要求

　　沼氣發(fā)電機(jī)房的通風(fēng)問題是機(jī)房設(shè)計(jì)中要特別注意解決的問題，特別是發(fā)電機(jī)組機(jī)房位于地下室時(shí)更要處理好，否則會直接影響發(fā)電機(jī)組的運(yùn)行。機(jī)組的排風(fēng)一般應(yīng)設(shè)熱風(fēng)管道，不宜讓柴油機(jī)散熱器把熱量散在機(jī)房內(nèi)，再由排風(fēng)機(jī)抽出。機(jī)房內(nèi)要有足夠的新風(fēng)補(bǔ)充。柴油機(jī)在運(yùn)行時(shí)，機(jī)房的換氣量應(yīng)等于或大于柴油機(jī)燃燒所需新風(fēng)量與維持機(jī)房室溫所需新風(fēng)量之和。進(jìn)風(fēng)口與出風(fēng)口宜分別布置在機(jī)組的兩端，以免形成氣流短路，影響散熱效果。

　　Requirements for the setup and site selection of biogas generator rooms1. Ventilation requirementsThe ventilation issue of the biogas generator room is a particularly important issue to address in the design of the room, especially when the generator set room is located in the basement. Otherwise, it will directly affect the operation of the generator set. The exhaust air of the unit should generally be equipped with a hot air duct, so as not to allow the diesel engine radiator to dissipate heat inside the room and then be extracted by the exhaust fan. There should be sufficient fresh air supply in the room. When the diesel engine is running, the ventilation rate of the room should be equal to or greater than the sum of the fresh air volume required for diesel engine combustion and the fresh air volume required to maintain the room temperature. The air inlet and outlet should be arranged at both ends of the unit to avoid forming an airflow shortcut, which will affect the heat dissipation effect.

　　2、防塵要求

　　發(fā)電機(jī)組機(jī)房防塵不好，也會對設(shè)備產(chǎn)生危害，在保證機(jī)房通風(fēng)的情況下，同時(shí)考慮到機(jī)房的防塵作用，加裝進(jìn)風(fēng)排風(fēng)百葉，保證機(jī)房的風(fēng)質(zhì)和風(fēng)量。

　　2. Dust Prevention Requirements

　　Poor dust prevention in the generator set room can also pose a hazard to the equipment. While ensuring proper ventilation in the room, it is also necessary to consider its dust prevention function by installing air intake and exhaust louvers to ensure the quality and volume of air in the room.

　　3、排煙系統(tǒng)

　　設(shè)置排煙系統(tǒng)的作用是將氣缸里的廢氣排放到室外。排煙系統(tǒng)應(yīng)盡量減少背壓，因?yàn)椋瑥U氣阻力的增加將會導(dǎo)致柴油機(jī)出力的下降及溫升的增加。排煙管敷設(shè)方式常用的是水平架空敷設(shè)和地溝內(nèi)敷設(shè)。在地下室常用的是水平架空敷設(shè)。

　　3. Exhaust SystemThe purpose of setting up an exhaust system is to discharge the exhaust gas from the cylinder to the outside. The exhaust system should minimize back pressure, as an increase in exhaust gas resistance will lead to a decrease in diesel engine output and an increase in temperature rise. Common methods of laying exhaust pipes include horizontal overhead laying and laying in trenches. Horizontal overhead laying is commonly used in basements.

　　4、基礎(chǔ)要求

　　基礎(chǔ)主要用于支撐發(fā)電機(jī)組及底座的全部重量，底座位于基礎(chǔ)上，機(jī)組安裝在底座上，底座上一般都采取減震措施。在高層建筑中一般采用高速發(fā)電機(jī)組，當(dāng)機(jī)組安裝在樓板上時(shí)，不采用重混凝土基礎(chǔ)，以免基礎(chǔ)過重而增加樓板荷重。當(dāng)機(jī)組位于建筑物底層時(shí)，應(yīng)按機(jī)組要求設(shè)置混凝土基礎(chǔ)。

　　4. Basic RequirementsThe foundation is primarily used to support the entire weight of the generator set and its base. The base sits on the foundation, and the unit is installed on top of it. Shock absorption measures are typically taken on the base. In high-rise buildings, high-speed generator sets are commonly used. When the unit is installed on the floor, a heavy concrete foundation is not recommended to avoid increasing the load on the floor due to an overly heavy foundation. When the unit is located on the ground floor of the building, a concrete foundation should be set up according to the requirements of the unit.

　　5、機(jī)房接地

　　發(fā)電機(jī)房一般使用三種接地。工作接地，發(fā)電機(jī)組中性點(diǎn)接地。保護(hù)接地，電氣設(shè)備正常不帶電的金屬外殼接地。防靜電接地，燃油系統(tǒng)的設(shè)備及管道接地。各種接地可與高層建筑的其他接地共用接地裝置，即采用聯(lián)合接地方式。

　　5. Machine room grounding: Three types of grounding are generally used in generator rooms. Working grounding, which refers to the grounding of the neutral point of the generator set. Protective grounding, which refers to the grounding of metal enclosures of electrical equipment that are normally not charged. Anti-static grounding, which refers to the grounding of equipment and pipelines in the fuel system. Various groundings can share grounding devices with other groundings in high-rise buildings, i.e., adopting a joint grounding method.

　　6、首層較佳

　　一般發(fā)電機(jī)組的機(jī)房都會設(shè)置在地下室，但如果有條件的話機(jī)房盡量設(shè)在首層。柴油發(fā)電機(jī)房的選址考慮到發(fā)電機(jī)組的進(jìn)風(fēng)、排風(fēng)、排煙等情況，首層是理想選擇，但困難點(diǎn)在于首層通常用于對外營業(yè)，且造價(jià)昂貴。

　　6. Preferably on the ground floorGenerally, the engine room of a generator set is located in the basement, but if conditions permit, it should be situated on the ground floor as much as possible. When selecting the location for a diesel generator room, factors such as air intake, exhaust, and smoke evacuation of the generator set should be considered. The ground floor is an ideal choice, but the difficulty lies in the fact that it is usually used for external business operations and is expensive to construct.
