工业尾气发电机组安装的注意事项
工业尾气发电机组通过回收工业生产中产生的尾气进行发电,安装过程需兼顾尾气特性、设备适配性与安全规范,才能实现高效运行与风险防控。其安装质量直接影响机组的发电效率、使用寿命及运行安全,需从场地规划、系统衔接、安全防护等多维度严格把控。
The industrial exhaust gas generator unit generates electricity by recycling the exhaust gas generated in industrial production. The installation process needs to take into account the characteristics of the exhaust gas, equipment compatibility, and safety regulations in order to achieve efficient operation and risk prevention. The installation quality directly affects the power generation efficiency, service life, and operational safety of the unit, and requires strict control from multiple dimensions such as site planning, system connection, and safety protection.
场地选择与布局是安装的基础,需满足尾气输送与设备运行需求。应优先选择靠近尾气源的区域,缩短输送管路长度,减少尾气在传输过程中的压力损失与热量损耗。场地需平整开阔,地面承重能力符合机组要求,根据设备重量浇筑混凝土基础,同时预留至少 1.5 米的维护通道,便于后期检修与部件更换。考虑到尾气可能含有腐蚀性成分,场地应避开低洼积水区域,做好排水设计,防止雨水浸泡设备底座引发锈蚀。此外,需远离居民区与明火作业点,避免尾气泄漏或燃烧排放物对周边环境造成影响。
Site selection and layout are the foundation of installation, and must meet the requirements of exhaust gas transportation and equipment operation. Priority should be given to selecting areas close to the exhaust source, shortening the length of the conveying pipeline, and reducing pressure and heat losses during the transmission of exhaust gas. The site needs to be flat and open, with a ground bearing capacity that meets the requirements of the unit. Concrete foundations should be poured according to the weight of the equipment, and at least 1.5 meters of maintenance access should be reserved for later maintenance and component replacement. Considering that the exhaust gas may contain corrosive components, the site should avoid low-lying water accumulation areas and have proper drainage design to prevent rainwater from soaking the equipment base and causing corrosion. In addition, it is necessary to stay away from residential areas and open flame work sites to avoid the impact of exhaust leaks or combustion emissions on the surrounding environment.
尾气输送系统的安装需注重密封性与防腐蚀。管路材质需根据尾气成分选择:含酸性气体的尾气需采用玻璃钢或衬塑钢管,避免金属管路被腐蚀泄漏;含粉尘的尾气需选用耐磨钢管,并在弯头处加装耐磨衬里,减少颗粒冲刷造成的磨损。管路连接采用法兰连接,密封垫片选用耐温耐腐材料,螺栓紧固均匀,确保无泄漏。管路需设置合理坡度,低点安装排污阀,定期排放冷凝液,防止液体积聚影响输送。同时,管路外需做保温处理,对高温尾气还需加装隔热层,避免热量流失与人员烫伤。
The installation of exhaust gas delivery system should pay attention to sealing and corrosion prevention. The material of the pipeline should be selected according to the composition of the exhaust gas: exhaust gas containing acidic gases should be made of fiberglass or plastic lined steel pipes to avoid corrosion and leakage of metal pipelines; Wear resistant steel pipes should be selected for exhaust gases containing dust, and wear-resistant linings should be installed at the bends to reduce wear caused by particle erosion. The pipeline connection adopts flange connection, and the sealing gasket is made of temperature resistant and corrosion-resistant materials. The bolts are tightened evenly to ensure no leakage. The pipeline should have a reasonable slope, and a drain valve should be installed at the low point to regularly discharge condensate and prevent liquid accumulation from affecting transportation. At the same time, insulation treatment should be carried out outside the pipeline, and a thermal insulation layer should be added to high-temperature exhaust gas to avoid heat loss and personnel burns.
设备定位与固定需保证稳定性,减少运行振动影响。机组安装前需校准水平度,通过调整垫铁使机身平稳,避免因倾斜导致部件磨损或润滑油泄漏。地脚螺栓需与基础预埋件牢固连接,拧紧后采用点焊固定,防止运行中松动。对于大功率机组,基础需设置减震装置,降低振动传递对厂房结构的影响,同时减少噪音扩散。机组与尾气管道、排烟管道的连接需采用柔性接头,吸收振动产生的位移,避免刚性连接导致管路开裂。
The positioning and fixation of equipment must ensure stability and reduce the impact of operational vibration. Before installing the unit, it is necessary to calibrate the levelness and adjust the shim to make the fuselage stable, avoiding component wear or lubricant leakage caused by tilting. The anchor bolts need to be firmly connected to the foundation embedded parts, and after tightening, they should be fixed by spot welding to prevent loosening during operation. For high-power units, shock-absorbing devices need to be installed on the foundation to reduce the impact of vibration transmission on the plant structure and minimize noise diffusion. The connection between the unit and the exhaust pipe and smoke exhaust pipe should use flexible joints to absorb the displacement caused by vibration and avoid rigid connections that may cause pipeline cracking.
电气与控制系统安装需符合安全规范,确保运行可靠。控制柜应安装在干燥通风处,远离粉尘与腐蚀性气体,与机组保持安全距离。电气线路敷设采用穿管方式,动力线与信号线分开布置,避免电磁干扰。接地系统需独立设置,机组外壳、控制柜、管道等金属部件均需可靠接地,防止静电积聚或漏电事故。控制系统的传感器需安装在代表性位置,确保检测数据准确,与机组的联动逻辑需提前调试,保障安全运行。
The installation of electrical and control systems must comply with safety regulations to ensure reliable operation. The control cabinet should be installed in a dry and ventilated area, away from dust and corrosive gases, and kept at a safe distance from the unit. The electrical wiring is laid in conduit, with power lines and signal lines arranged separately to avoid electromagnetic interference. The grounding system needs to be independently set up, and metal components such as the unit casing, control cabinet, and pipelines must be reliably grounded to prevent static electricity accumulation or leakage accidents. The sensor of the control system shall be installed at a representative location to ensure accurate detection data. The linkage logic with the unit shall be debugged in advance to ensure safe operation.
安全设施配置是安装的重要环节,需覆盖预防与应急需求。在尾气输送管道上安装紧急切断阀,与机组形成联锁,当检测到泄漏或浓度超标时自动关闭。机组周围设置可燃气体检测报警器,并与通风系统联动,超标时自动启动风机换气。消防设施需配备灭火器、消防沙,对于大型机组还需设置消防水系统。此外,安装区域需设置醒目的安全标识,配备应急照明与紧急停车按钮。
The configuration of safety facilities is an important part of installation, which needs to cover prevention and emergency needs. Install an emergency shut-off valve on the exhaust gas delivery pipeline, which is interlocked with the unit and automatically closes when a leak or concentration exceeds the standard is detected. Combustible gas detection alarms are installed around the unit and linked with the ventilation system to automatically start the fan for ventilation when exceeding the standard. Firefighting facilities should be equipped with fire extinguishers and fire sand, and for large units, a fire water system should also be installed. In addition, prominent safety signs should be set up in the installation area, equipped with emergency lighting and emergency stop buttons.
