沼气发电机组排气系统温度较高，其燃料易燃易爆，操作过程中若稍不注意，就有可能酿成灾祸。因此，在机房内使用沼气发动机组时，用户要遵守以下几点安全规定，另外还要根据具体情况，制定安全操作规程，并严格遵守。

The temperature of the exhaust system of the biogas generator unit is high, and its fuel is flammable and explosive. If you do not pay attention to it, it may cause disaster. Therefore, when using biogas engine set in the machine room, the user should comply with the following safety regulations, and in addition, according to the specific situation, formulate and strictly comply with the safety operation regulations.

一、设备要求

1、 Equipment requirements

1、机房内电气设施应为防爆型，进行电气维修时，须切断电源。

1. The electrical facilities in the machine room shall be explosion-proof, and the power supply must be cut off during electrical maintenance.

2、在沼气管道进机房处，应设置紧急阀门，以备厂房内发生紧急情况时，可迅速切断气源，此阀门应离操作间较近。

2. An emergency valve shall be set at the place where the biogas pipeline enters the machine room, in case of emergency in the plant, the gas source can be cut off quickly, and the valve shall be close to the operation room.

3、机房内要安置沼气浓度报警器，好在机房对角处安两个，当环境浓度在爆炸和中毒浓度范围以内时，须强制通风，降低浓度后方可启动机组。

3. The biogas concentration alarm should be installed in the machine room, and two should be installed at the opposite corners of the machine room. When the ambient concentration is within the range of explosion and poisoning concentration, forced ventilation should be required, and the unit can be started only after the concentration is reduced.

二、沼气管道要求

2、 Requirements for biogas pipeline

1、沼气管道应采用钢管，管壁不应太薄，接头处要密封可靠，沼气管线连接完成后，用沼气检测仪或肥皂水检测管线渗漏情况，特别是法兰、阀门等接头处。

1. The biogas pipeline shall be made of steel pipes, the pipe wall shall not be too thin, and the joints shall be sealed reliably. After the biogas pipeline is connected, the biogas detector or soapy water shall be used to detect the leakage of the pipeline, especially the joints of flanges, valves, etc.

2、应定期检查阀门，应无沼气泄漏、损坏等现象，阀门周围应无妨碍阀门操作的堆积物，阀门应定期进行启闭操作和维护保养，无法启闭或关闭不严的阀门，应及时维修或更换。

2. The valve shall be checked regularly to ensure that there is no methane leakage, damage and other phenomena. There shall be no accumulation around the valve that hinders the operation of the valve. The valve shall be regularly opened and closed for operation and maintenance. The valve that cannot be opened or closed tightly shall be repaired or replaced in time.

3、沼气管线上的胶管应定期更换，严禁使用过期老化胶管。

3. The rubber hose on the biogas pipeline should be replaced regularly. It is strictly prohibited to use expired and aged rubber hose.

4、对机组及沼气管线进行运行、维护和抢修时，须可靠地切断沼气来源并将内部沼气排净，未查明事故原因和采取必要安全措施前，不得向沼气设施恢复送气。进行维护检修时，应采取防爆措施或使用防爆工具，严禁用铁器等工具进行敲击作业。

4. During the operation, maintenance and emergency repair of the unit and biogas pipeline, the source of biogas must be reliably cut off and the internal biogas must be discharged. Before the cause of the accident is identified and the necessary safety measures are taken, the gas supply to the biogas facilities cannot be resumed. Explosion-proof measures or tools shall be taken during maintenance and overhaul. It is strictly forbidden to use tools such as iron tools to knock.

5、沼气泄漏的抢修应在切断气源后进行，当泄漏处已发生燃烧时，应先采取措施控制火势后再切断气源，严禁管道内出现负压。

5. The emergency repair of biogas leakage should be carried out after cutting off the gas source. When the leakage has been burned, measures should be taken to control the fire before cutting off the gas source. Negative pressure in the pipeline is strictly prohibited.

此外沼气发电机工作时，工作人员应经常巡视、检查沼气发电机组的运行情况，发现问题应及时调整或上报有关领导，以免出现意外事项或危险。更多的相关事项就来我们网站//www.gz-yanye.com咨询！

In addition, when the biogas generator is working, the staff should regularly inspect and check the operation of the biogas generator unit, and timely adjust or report to the relevant leaders in case of any problems, so as to avoid accidents or dangers.
