沼氣發電機組排氣系統溫度較高，其燃料易燃易爆，操作過程中若稍不注意，就有可能釀成災禍。因此，在機房內使用沼氣發動機組時，用戶要遵守以下幾點安全規定，另外還要根據具體情況，制定安全操作規程，并嚴格遵守。

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、設備要求

1、 Equipment requirements

1、機房內電氣設施應為防爆型，進行電氣維修時，須切斷電源。

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

2、在沼氣管道進機房處，應設置緊急閥門，以備廠房內發生緊急情況時，可迅速切斷氣源，此閥門應離操作間較近。

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、機房內要安置沼氣濃度報警器，好在機房對角處安兩個，當環境濃度在爆炸和中毒濃度范圍以內時，須強制通風，降低濃度后方可啟動機組。

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、沼氣管道要求

2、 Requirements for biogas pipeline

1、沼氣管道應采用鋼管，管壁不應太薄，接頭處要密封可靠，沼氣管線連接完成后，用沼氣檢測儀或肥皂水檢測管線滲漏情況，特別是法蘭、閥門等接頭處。

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、應定期檢查閥門，應無沼氣泄漏、損壞等現象，閥門周圍應無妨礙閥門操作的堆積物，閥門應定期進行啟閉操作和維護保養，無法啟閉或關閉不嚴的閥門，應及時維修或更換。

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、沼氣管線上的膠管應定期更換，嚴禁使用過期老化膠管。

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

4、對機組及沼氣管線進行運行、維護和搶修時，須可靠地切斷沼氣來源并將內部沼氣排凈，未查明事故原因和采取必要安全措施前，不得向沼氣設施恢復送氣。進行維護檢修時，應采取防爆措施或使用防爆工具，嚴禁用鐵器等工具進行敲擊作業。

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、沼氣泄漏的搶修應在切斷氣源后進行，當泄漏處已發生燃燒時，應先采取措施控制火勢后再切斷氣源，嚴禁管道內出現負壓。

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.

此外沼氣發電機工作時，工作人員應經常巡視、檢查沼氣發電機組的運行情況，發現問題應及時調整或上報有關領導，以免出現意外事項或危險。更多的相關事項就來我們網站http://m.hdlelisa.com咨詢！

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.
