1）快速安装

将仪器放置在平稳水平位置上，保证仪器不会晃动，且周围环境无强电磁干扰和强烈震动。 将仪器接地柱接地，通过仪器电源线连接AC 220V电源。

RS-232及4-20mA信号输出接线，方法请参照[2.3 线路安装及配置]。

注意进入“采样气体入口”前的气体必须经过净化、干燥处理，要求粉尘过滤精度小于1μm，气体无冷凝现象。若采样点气体压力为负压或者压力小于2KPa，应该在“采样气体入口”前端管路安装采样气泵。

将排气管连接分析仪器的背板“采样气体出口”，然后将采样管连接分析仪器的背板“采样气体入口”，调节仪器面板的浮子流量计，调整流量至0.7~1.2L/min。采样管及排气管内径为4mm、外径为6mm的PU管、氟橡胶管或特氟龙管。具体方法请参照[2.2 气体管路安装及配置]。

2）快速测量

开启分析仪器电源，分析仪器预热15min；

预热完毕，仪器开始测量，仪器测量界面显示气体浓度； 若通过4-20mA输出，则输出端子可以测量输出电流； 若通过RS-232输出到上位机，本公司免费提供通讯协议。

3）快速调零

按“确认键”进入密码验证界面，默认为“9999”；

将采样气管拧下，往仪器“采样气体入口”通入新鲜空气，调节流量为0.7~1.2L/min

； 进入系统设置界面，通过上、下方向键将光标移动到“调零”处，开始调零过程； 具体方法请参照[5.2.3 调零]

调零过程需要持续通气约30秒。

4）快速标定

按“确认键”进入密码验证界面，默认为“9999”；

进入系统设置界面，通过上、下方向键将光标移动到“标定”处，按“确认键”进入“零点标定”界

面；

在所要标定组分处，输入气体的标称浓度，按“确定键”后将光标移动到“存储”位置；

将采样气管拧下，将标定气体输出管线连接到仪器“采样气体入口”，调节零气标准气瓶减压阀至气

体流量为0.7~1.2L/min；

当标定界面右上角的“UnStable”标志变为“Stable”时，按“存储键”保存标定数据即可，仪器自

动跳转到“终点标定”界面；

关闭“零点标定”标准气体，并将输气管线拧下；将量程气体管线连接到仪器“采样气体入口”调节

7

标准气瓶减压阀至气体流量为0.7~1.2L/min；

当标定界面右上角的“UnStable”标志变为“Stable”时，按“存储键”保存标定数据即可，仪器自

动跳转到测量界面；

“零点标定”与“终点标定”必须连续完成，否则标定无效；

在标定过程中，请仔细辩别通入的标准气体是零气还是量程气，并正确输入气体标称值；观察仪器流量计是否显示在0.7~1.2L/min范围内； 具体方法参照[5.2.4 标定]。

红外烟气分析仪器能够测量烟气成分中的CO、CO2、NO、SO2、O2的组分浓度，其中CO、CO2、SO2

、NO采用国际先进的微流红外技术测量，O2采用长寿命电化学传感器测量。该仪器能够适用于锅炉排烟脱硫、脱硝前后烟气的测量。

1.1工作原理

①--红外光源 ②--切光器 ③—切光电机 ④—测量气室 ⑤--检测器 ⑥—微流传感器 ⑦、⑧—第2组分气室及检测器 ⑨--信号处理及输出系统

微流红外检测技术的工作原理如上图所示，首先，红外光源①发出的红外光，经过切光器②进入测量气室④；由于SO2、NO、CO、CO2、CH4等异种原子构成的分子对红外光具有吸收特性，若测量气室④中存在上述气体，则进入测量气室的部分红外光会被吸收，未被吸收的红外光进入检测器⑤；检测器由前气室、后气室、微流传感器（6）组成，前、后气室充满待测组分的气体。在红外光的作用下，检测器前、后气室中的气体发生膨胀；由于存在膨胀差异，会导致前、后气室之间产生微小的流量；微流传感器⑥检测到该流量后，会产生一个交流电压信号，经信号处理及输出系统⑨后得到气体的浓度。

1.2仪器特点

红外烟气分析仪采用国际领先的微流红外检测技术测量样气中NO、SO2、CO、CO2的浓度，采用电化学方式测量O2的浓度，具有以下特点：

能够测量低量程气体浓度； 测量精度高； 工作稳定；

烟气中气态水对SO2、NO测量没有影响；

烟气中采样流量对SO2、NO、CO、CO2、CH4的测量无影响。

1.3应用领域

该仪器可以适用于发电厂的燃煤烟囱，钢铁厂、水泥厂、炼铝厂、有色金属冶炼厂、磷肥厂、硝酸厂、硫酸厂、石油化工厂、化学纤维厂的大型工业烟囱等固定污染源废气浓度的连续监测。

2仪器安装

2.1仪器本体安装

安装条件如下：

1） 建议将分析仪器放置在平稳、能承受仪器重量的场所（如水平桌面、标准19英寸机柜），避免仪器翻

倒或坠落。 2） 请在室内使用。

3） 请避开有强烈振动和强磁场干扰的场所。 4） 请选择环境空气清洁的场所。

5） 供电电源：220V±44V 交流 50Hz

±1Hz。 6） 环境温度：0～50℃。

2.2气体管路安装及配置

通常工业气体样气中含有粉尘、液态水、水蒸气，因此采样气体需要满足以下条件：

2.2.1采样气体条件

1） 严禁灰尘进入仪器气路管道，可能引起仪器工作不正常或测量不准确。因此，进入分析仪器采样气体

入口的气体必须经过粉尘过滤，推荐过滤精度1μm。

2） 应该避免液态水进入分析仪器，并且要防止水蒸气在分析仪器内发生冷凝。因此，进入分析仪器采样

气体入口的气体必须经过除湿处理。

3） 保证进入分析仪器的气体温度为0～50℃。若温度过高，应该使用冷凝器对气体进行降温。 4） 工作流量应该控制在0.7～1.2 L/min范围，并保持流量稳定。压力过高或流量波动，可能造成分析仪

器工作异常，严重情况下可能造成仪器部件损坏。

2.2.2采样装置选择

1） 采样气体管路应保证防止气体吸附和管路破裂。气体管路尽量减短，以提高仪器的测量响应速度。严

禁使用粘有油脂类的采样管、减压阀等采样器件，请采用清洁、干净的气体管件及接头。 2） 分析仪器的气体入口与出口接口管路规格为Φ4×6mm （内径×外径）。 3） 使用前应该检查并保证分析仪器的粉尘过滤器的气密性。

2.2.3采样管路工作

1） 采样气体、零点气体、量程气体由采样气体入口进入仪器，经流量计、气体传感器，再由采样气体出

口排出。

2） 采样气体出口与室外大气或采样管道相通，保证排放安全，避免分析仪器的传感器内产生较大气压。 3） 旋转前面板流量计的调节按钮，调节气体流量至0.7~1.2L/min。

14

2.3线路安装及配置

模拟及串口输出端口（AIO/RS-232）、数字输入端口1（DIO1）、数字输入端口2（DIO2）、电源插座和接地柱位于分析仪的背面。参见下图。

1） 模拟及串口输出端口（AIO/RS-232）

串口接口与DB9接头（孔式）的连接方式参见下图。

15

连接串口数据传输线时，请首先断开分析仪器的电源，以避免仪器损坏。 2） 报警输出端口DIO1

1-4 --- 空（备用）；

5-6 --- O2下限报警输出； 7-8 --- O2上限报警输出； 9-10 --- NO下限报警输出； 11-12 --- NO上限报警输出； 13-14 --- SO2下限报警输出； 15-16 --- SO2上限报警输出；

3仪器运行

3.1运行准备

请首先确认如下几项工作是否完成： 1） 分析仪器按照要求平稳安装。

2） 检查气体管路是否连接正确。采样装置、排气管道是否安装到位。 3） 检查线路是否连接正确。

3.2仪器预热及运行

仪器运行步骤如下：

1） 将分析仪正面面板上的开关按键拨到“I”位置，仪器显示导入界面，如下图所示。

2） 分析仪器开始预热，建议预热时间为15分钟。预热完毕后分析仪基本达到稳定状态。

※ 分析仪器预热过程中，浓度显示值可能不准确或者不稳定，属于正常现象。

3） 预热结束后，仪器零点漂移或者量程点漂移超出允许值时，需要对分析仪器进行调零校正或者用户标

定。

4） 将采样气体导入分析仪器，开始测量。

注：预热过程中，用户也可开始测量，可能出现测试值偏差较大或不正确的现象；用户可调零后再重新测试，或等待足够预热时间。
