    co-吸附催化燃烧技术说明:浓缩蓄热催化燃烧技术,是废气先通过预处理,去除绝大部分的粉尘和颗粒状物质等,然后将废气引入阻火器。再送入浓缩系统,将空气与废气分离,废气部分进入下一部分处理工序,空气部分进入排放口排放;废气进行蓄热系统,使废气达到起燃温度后进入催化室,在催化剂的作用下进行催化燃烧。经一定时间,保证高净化率。经净化后的尾气在进入蓄热床进行热交换,将燃烧产生的大部分热量储存下来,然后由风机抽出高空排放。

      co-吸附催化燃烧特点分析:

      净化装置是结合“吸附(吸附净化,投资省)和催化燃烧(脱附再生,运行经济,低温燃烧节能)”两种技术的优势,同时有效消除各自的缺陷而创新设计的组合新技术,即通过吸附浓缩使废气达标排放,饱和的吸附剂经催化燃烧脱附再生。

      系统运行稳定,净化效率高,全自动控制。

      采用新型的蜂窝活性炭吸附材料:净化效率高,风阻小易脱附,可再生,无二次污染。

      有机物在催化室燃烧开始后,其燃烧热能可足以维持其反应所需的能量,生成的高温热空气送回吸附箱对饱和吸附剂再生,脱附气体回到催化室在燃烧,热能循环利用,运行费用低,节能效果显著。

      设备配套惰性气体保护系统,脱附过程中当碳层测温信号经过PLC处理判断温度发生异常时,系统自动关闭补冷风阀,惰性气体保护系统自动启动,惰性气体通过脱附管道,电磁阀注入活性炭床内进行脱附,起到防火作用。

      设备处于三种状态下(停机,脱附,吸附),保证电柜正常供电,PLC自动全天侯对碳层温度进行监控和防范保护。

      混流交换器:催化燃烧排出高温烟气~150℃通过换热器换热后降低至~90℃在送入活性炭吸附床,用于对活性炭的解析。
      co-吸附催化燃烧系统组成及功能

      催化燃烧器电控制系统由PLC控制器、文本显示器、变频调速器、点火器、紫外线传感器、热电偶等电控设备以及风机,另外由零压阀调节燃气与空气的比例。催化燃烧电气控制系统工作过程分为三个状态:燃烧器工作状态、停止状态及参数设定状态。在工作状态中又分为点火过程和燃烧过程。由安装的热电偶检测出温度,送文本显示器显示。PLc具有模拟量输入、输出模块,检测火焰燃烧信号和热电偶温度信号,将检测到的信号与设定的信号经过比较运算后,通过0~10V电信号控制变频器的输出频率来调整风机的转速,保持燃烧器的燃烧温度,这就是构成以设定温度为基准的控制系统;自动检测燃烧器温度信号与设定的温度比较,输出各类报警信号或直接停机。显示器可以显示燃气流量、燃烧温度和变频器输出频率。设定参数和工作状态等信息;可以通过显示器在线调整运行温度参数,修改设定温度控制风机的运行。该系统还设有多种保护功能,尤其是较强的逻辑互锁功能,从而保证系统工作可靠,并且具有较为完善的控制功能。

      该系统工作过程主要划分为三种状态参数设定、燃烧运行和燃烧停止。

      1.参数设定状态

      此状态为燃烧工作之前做好数据的准备。可根据需要分别设定点火温度和变频器起动时的频率,控制风机的风量。点火温度是为了保证点火过程的可靠性。起动频率保证催化燃烧器在刚点燃时的有焰燃烧,这时的燃烧比不易太低,风量不能过大。

      2.燃烧运行状态

      (1)燃烧起动过程

      当控制系统在待命的状态下,接到输入的起动命令,将进入燃烧运行状态,首先是控制系统进行自检,之后进行前吹扫,变频器输出信号控制风机的旋转,空气风量由低速渐变为高速再逐渐变为低速,新鲜空气风吹过燃烧炉盘,以保证炉内没有残留燃气的存在,保证点火过程的安全可靠。具体操作是变频器先起动,PLc模拟输出信号使变频器频率从起动设定频率开始上升,达到一定频率后保持一定时间后再下降,完成起动前的吹扫。之后,发出点火信号,高压点火器工作,同时打开点火管道的阀门,小火点燃。通过紫外线传感器的检测到期小火点燃后,打开主燃气阀门。这时催化燃烧炉盘进行有焰燃烧,直到检测温度信号达到设定的点火关闭温度,点火阀门关闭,完成点火过程,进入到燃烧调节阶段。

      (2)燃空比的调定

      有文献表明,催化燃烧时的“燃气/空气比值”范围一般在4%~11%之间;在一定的燃烧条件之下,燃/空比为6%时,天然气就能实现较好的催化燃烧效果,燃烧系统就可以得到*大的热效率,同时又能取得较好的排放效果。

      本系统的燃气一空气比的调节是通过零压阀实现的。当改变风机的空气风量时,燃/空比也能随之被改变,以达到催化燃烧器燃烧工作的要求。在起动时只要调节输出变频器的频率就能达到点火时要求的从有焰燃烧到催化燃烧的燃/空比的变化。

      (3)燃烧温度调节

      燃烧器温度调节可以通过文本显示器的键盘输入,改变变频器的输出频率,调节适当的风量。当风量增大,燃烧温度超过设定值,则PLc控制变频器降低输出频率,减少出风量来稳定燃烧器的温度。若变频器输出频率低于设定值(风机出风量频率,设为5Hz),而出风量仍高于设定值时,PLc开始计时,若在一定时间内,降低到设定值,PLc放弃计时,继续变频调速运行;若在一定时间内温度仍高于设定,PLc将继续调节,直至达到设定值。由PLc经PID运算后控制变频器的频率输出;如温度不够,则频率上升,延时保持一定时间。反之亦然。

    Description of co-adsorption catalytic combustion technology: The concentrated regenerative catalytic combustion technology is that the exhaust gas is pretreated to remove most of the dust and particulate matter, and then the exhaust gas is introduced into the flame arrester. It is sent to the concentrating system to separate the air from the exhaust gas. The exhaust gas enters the next part of the treatment process, and the air part is discharged into the discharge port. The exhaust gas is stored in the heat storage system, so that the exhaust gas reaches the light-off temperature and enters the catalytic chamber to catalyze under the action of the catalyst. combustion. After a certain period of time, a high purification rate is guaranteed. The purified exhaust gas enters the regenerator bed for heat exchange, and stores most of the heat generated by the combustion, and then the high-altitude discharge is extracted by the fan.

    Analysis of characteristics of co-adsorption catalytic combustion:

    The purification device is a combination of new technologies that combine the advantages of adsorption (adsorption purification, investment reduction) and catalytic combustion (desorption regeneration, economical operation, low-temperature combustion and energy saving), while effectively eliminating their respective defects and innovative design, namely The exhaust gas reaches the standard discharge by adsorption and concentration, and the saturated adsorbent is desorbed and regenerated by catalytic combustion.

    The system runs stably, with high purification efficiency and fully automatic control.

    Adopting new type of honeycomb activated carbon adsorption material: high purification efficiency, small wind resistance, easy to desorb, renewable, no secondary pollution.

    After the combustion of the organic substance in the catalytic chamber begins, the combustion heat energy can be sufficient to maintain the energy required for the reaction, and the generated high-temperature hot air is sent back to the adsorption tank to regenerate the saturated adsorbent, and the desorbed gas is returned to the catalytic chamber for combustion, and the heat energy is recycled. Low operating costs and significant energy savings.

    The equipment is equipped with an inert gas protection system. When the carbon layer temperature measurement signal is processed by the PLC to determine the temperature abnormality during the desorption process, the system automatically closes the supplementary cold air valve, the inert gas protection system starts automatically, the inert gas passes through the desorption pipe, and the solenoid valve is injected. The desorption of the activated carbon bed serves as a fireproofing effect.

    The equipment is in three states (stop, desorption, adsorption) to ensure normal power supply to the cabinet, and the PLC automatically monitors and protects the carbon layer temperature throughout the day.

    Mixed-flow exchanger: catalytic combustion to discharge high-temperature flue gas ~150 ° C through the heat exchanger heat transfer and reduced to ~90 ° C in the activated carbon adsorption bed for the analysis of activated carbon.

    Composition and function of co-adsorption catalytic combustion system

    The catalytic burner electric control system consists of PLC controller, text display, frequency converter, igniter, ultraviolet sensor, thermocouple and other electronic control equipment and fan. In addition, the ratio of gas to air is adjusted by zero pressure valve. The working process of the catalytic combustion electrical control system is divided into three states: the burner operating state, the stopping state and the parameter setting state. In the working state, it is divided into an ignition process and a combustion process. The temperature is detected by the installed thermocouple and sent to the text display. PLc has analog input and output modules, detects flame combustion signal and thermocouple temperature signal, compares the detected signal with the set signal, and then controls the output frequency of the inverter through 0~10V electric signal to adjust the fan. The rotational speed maintains the combustion temperature of the burner. This is the control system that constitutes the set temperature. The automatic detection of the burner temperature signal is compared with the set temperature, and various types of alarm signals are output or directly stopped. The display can display gas flow, combustion temperature and inverter output frequency. Set parameters and working status and other information; you can adjust the operating temperature parameters online through the display, and modify the set temperature to control the operation of the fan. The system also has a variety of protection functions, especially the strong logic interlock function, to ensure reliable system operation, and has a more complete control function.

    The working process of the system is mainly divided into three state parameter settings, combustion operation and combustion stop.

      1. Parameter setting status

    This state prepares the data for the combustion work. The ignition temperature and the frequency at which the inverter is started can be set separately to control the air volume of the fan. The ignition temperature is to ensure the reliability of the ignition process. The starting frequency ensures the flaming combustion of the catalytic burner just after ignition, when the combustion ratio is not too low and the air volume cannot be too large.

      2. Combustion operating state

    (1) Combustion start process

    When the control system is in standby state, it receives the input start command and enters the combustion operation state. First, the control system performs self-test, then the pre-purge, the inverter output signal controls the rotation of the fan, and the air volume is changed from low speed. For high speed and then gradually become low speed, fresh air wind blows through the combustion furnace plate to ensure that there is no residual gas in the furnace to ensure the safety and reliability of the ignition process. The specific operation is that the inverter starts first, and the PLc analog output signal causes the frequency of the inverter to rise from the starting set frequency. After reaching a certain frequency, it will continue to fall for a certain period of time to complete the purge before starting. After that, an ignition signal is issued, and the high-voltage igniter operates, and at the same time, the valve of the ignition pipe is opened, and a small fire is ignited. After the ignition of the UV sensor expires, the main gas valve is opened after ignition. At this time, the catalytic combustion furnace disk is subjected to flaming combustion until the detected temperature signal reaches the set ignition off temperature, the ignition valve is closed, the ignition process is completed, and the combustion adjustment phase is entered.

    (2) Setting of fuel-air ratio

    It has been shown in the literature that the "gas/air ratio" range during catalytic combustion is generally between 4% and 11%; under certain combustion conditions, natural gas can achieve better catalysis when the fuel/air ratio is 6%. The combustion effect, the combustion system can get the maximum thermal efficiency, and at the same time can achieve better emissions.

    The gas-to-air ratio adjustment of the system is achieved by a zero pressure valve. When the air volume of the fan is changed, the fuel/air ratio can also be changed to meet the requirements of the catalytic burner combustion work. The fuel/air ratio change from flaming to catalytic combustion required for ignition can be achieved by simply adjusting the frequency of the output inverter during starting.

    (3) combustion temperature adjustment

    The burner temperature adjustment can be changed through the keyboard input of the text display to change the output frequency of the inverter and adjust the appropriate air volume. When the air volume increases and the combustion temperature exceeds the set value, the PLc controls the inverter to reduce the output frequency and reduce the air volume to stabilize the burner temperature. If the output frequency of the inverter is lower than the set value (the fan air output frequency is set to 5 Hz), and the air output is still higher than the set value, the PLc starts counting. If it falls to the set value within a certain period of time, the PLc gives up. Timing, continue to variable frequency speed control; if the temperature is still higher than the setting within a certain period of time, PLc will continue to adjust until the set value is reached. The frequency output of the inverter is controlled by the PLc after the PID operation; if the temperature is not enough, the frequency rises and the delay is maintained for a certain time. vice versa.
