本发明的目的是提供一种用于烟气余热回收系统的微藻固碳装置，以解决上述现有技术存在的问题，利用微藻吸收烟气中的二氧化碳，减少了二氧化碳的排放。The object of the present invention is to provide a microalgae carbon fixation device used in a flue gas waste heat recovery system to solve the above-mentioned problems in the prior art, and use microalgae to absorb carbon dioxide in the flue gas, reducing the emission of carbon dioxide.
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
燃气锅炉烟气经过烟气余热回收后，烟气温度一般为10～50℃，CO2浓度约为8％左右，饱和烟气，微弱的酸性。大部分微藻生长周期为4～10天，能适应的CO2浓度<5％，适应的温度为25℃左右，烟气的弱酸性多微藻生长没有影响。极少部分微藻可以适应CO2浓度超过10％、温度超过30℃的环境；因此要利用常用的微藻吸收燃气锅炉烟气经过烟气余热回收后的烟气中的CO2，需要对烟气进行升温或降温，大部分藻类同时需要降低CO2的浓度。After the flue gas of the gas-fired boiler is recovered by flue gas waste heat, the temperature of the flue gas is generally 10-50°C, the concentration of CO2 is about 8%, and the flue gas is saturated and weakly acidic. The growth period of most microalgae is 4 to 10 days, and the CO 2 concentration that can be adapted is <5%, and the adaptable temperature is about 25°C, and the weak acidity of flue gas has no effect on the growth of many microalgae. A very small number of microalgae can adapt to the environment where the CO2 concentration exceeds 10% and the temperature exceeds 30°C; therefore, to use commonly used microalgae to absorb CO2 in the gas boiler flue gas after flue gas waste heat recovery, it is necessary to heat up or cool down the flue gas, and most algae need to reduce the CO2 concentration at the same time.
基于上述考虑，本发明提供一种用于烟气余热回收系统的微藻固碳装置，参考附图1和附图2所示，烟气余热回收系统1设于烟气排放的烟道2上，烟道2一端与锅炉或直燃机3连通，锅炉或直燃机3运行时，天然气与空气按一定比例混合燃烧后，排出烟气。在烟道2上安装的烟气余热回收系统1，通过低温热水，实现烟气与水换热，从而实现回收烟气余热的目的；烟气余热回收系统1两端的烟道2侧壁分别连通有第一支道4和第二支道5，第一支道4和第二支道5末端分别与混气室6的第一进气口和第二进气口连通，混气室6外接有空气入口通道7，第一支道4、第二支道5和空气入口通道7处均分别设置有电动调节风阀8，电动调节风阀8电连接有控制端9。第一支道4和第二支道5上均分别设有手动风阀10便于手动控制通断，第一支道4、第二支道5和空气入口通道7上均分别设有温度传感器11，温度传感器11位于混气室6和电动调节风阀8之间，温度传感器11与控制端9连接；混气室6的出气管连通有微藻培养箱12，混气室6的出气管上设有温度传感器11和二氧化碳浓度传感器13，温度传感器11和二氧化碳浓度传感器13分别与控制端9连接，微藻培养箱12末端设有排烟口，微藻培养箱12的排烟口处设有变频风机14，变频风机14与控制端9连接；烟气余热回收系统1前后的烟气温度不同，烟气余热回收系统1前的烟温一般为50℃以上，烟气余热回收系统1后的烟温一般为10～50℃以上；烟气余热回收系统1前后的烟气CO2浓度基本相同，大约8％左右。配置不锈钢材质的混气室6，分别连接烟气余热回收前高温烟气、烟气余热回收后低温烟气和空气；控制箱内的控制系统连接上述温度传感器11、二氧化碳浓度传感器13、照度传感器15、电动调节风阀8和变频风机14，配置控制器和触摸屏，实现烟气量、烟气温度和二氧化碳浓度控制，分别监测三个入口的气体温度，通过电动调节风阀8调节三种气体的含量，混气室6与微藻培养箱12之间使用不锈钢烟道连接，并安装温度传感器11和二氧化碳浓度传感器13，实时监测烟气的温度和CO2浓度，使混气室6内的烟气符合微藻生长要求的温度和二氧化碳浓度；烟气在排烟口风机的作用下进入微藻培养箱12，微藻吸收部分二氧化碳后排出烟气。Based on the above considerations, the present invention provides a microalgae carbon fixation device used in a flue gas waste heat recovery system. Referring to Figures 1 and 2, the flue gas waste heat recovery system 1 is installed on the flue 2 for flue gas discharge, and one end of the flue 2 is connected to the boiler or the direct combustion engine 3. When the boiler or the direct combustion engine 3 is running, natural gas and air are mixed and burned in a certain proportion, and the flue gas is discharged. The flue gas waste heat recovery system 1 installed on the flue 2 realizes heat exchange between the flue gas and water through low-temperature hot water, thereby achieving the purpose of recovering the waste heat of the flue gas; the side walls of the flue 2 at both ends of the flue gas waste heat recovery system 1 are connected with the first branch 4 and the second branch 5 respectively. The air valve 8 is adjusted, and the electric air valve 8 is electrically connected to a control terminal 9 .第一支道4和第二支道5上均分别设有手动风阀10便于手动控制通断，第一支道4、第二支道5和空气入口通道7上均分别设有温度传感器11，温度传感器11位于混气室6和电动调节风阀8之间，温度传感器11与控制端9连接；混气室6的出气管连通有微藻培养箱12，混气室6的出气管上设有温度传感器11和二氧化碳浓度传感器13，温度传感器11和二氧化碳浓度传感器13分别与控制端9连接，微藻培养箱12末端设有排烟口，微藻培养箱12的排烟口处设有变频风机14，变频风机14与控制端9连接；烟气余热回收系统1前后的烟气温度不同，烟气余热回收系统1前的烟温一般为50℃以上，烟气余热回收系统1后的烟温一般为10～50℃以上；烟气余热回收系统1前后的烟气CO 2浓度基本相同，大约8％左右。配置不锈钢材质的混气室6，分别连接烟气余热回收前高温烟气、烟气余热回收后低温烟气和空气；控制箱内的控制系统连接上述温度传感器11、二氧化碳浓度传感器13、照度传感器15、电动调节风阀8和变频风机14，配置控制器和触摸屏，实现烟气量、烟气温度和二氧化碳浓度控制，分别监测三个入口的气体温度，通过电动调节风阀8调节三种气体的含量，混气室6与微藻培养箱12之间使用不锈钢烟道连接，并安装温度传感器11和二氧化碳浓度传感器13，实时监测烟气的温度和CO 2浓度，使混气室6内的烟气符合微藻生长要求的温度和二氧化碳浓度；烟气在排烟口风机的作用下进入微藻培养箱12，微藻吸收部分二氧化碳后排出烟气。
进一步优选的，微藻培养箱12采用透明塑料材质制成，微藻培养箱12顶部设有灯带箱，灯带箱内配置有补光灯带16，灯带箱与微藻培养箱12分隔布置，补光灯带16能够对微藻培养箱12内的微藻提供光照，灯带箱内顶部设置的照度传感器15，监测照度情况，不论微藻培养箱12位于室内还是室外，均根据照度情况开关灯带；即自然光照度高时，关闭灯带；自然光照度低时开启灯带。以此保证微藻光照充足，快速生长。微藻培养箱和混气室底部均分别设有冷凝水排水口，便于及时将内部冷凝水排出。Further preferably, the microalgae incubator 12 is made of transparent plastic material, the top of the microalgae incubator 12 is provided with a light strip box, and the light strip box is equipped with a supplementary light strip 16. The light strip box and the microalgae incubator 12 are arranged separately, and the supplementary light strip 16 can provide light to the microalgae in the microalgae incubator 12. The illuminance sensor 15 installed on the top of the light strip box monitors the illuminance. Turn off the light strip; turn on the light strip when the natural light is low. In order to ensure that the microalgae have sufficient light and grow rapidly. The bottom of the microalgae incubator and the gas mixing chamber are respectively equipped with condensate drains to facilitate timely discharge of internal condensate.
本发明工作时，根据微藻数量规模，设定排烟变频风机的频率，保证烟气流通量基本恒定。根据变频风机频率，即烟气流量，等比例计算出高温烟气、低温烟气和空气三个电动调节风阀8的开度之和，保证合理的烟气流量。根据混气室和培养箱连接管的温度传感器和二氧化碳浓度传感器，实时监测混合后的烟气温度和CO2浓度，实时调节三个电动调节风阀8的开度，保证烟气温度和CO2浓度处于合适的范围内。于不同的实施例中，当空气温度较高时，如夏季，可选用耐高温的微藻，使用上述装置进行微藻固碳。When the present invention works, the frequency of the smoke-exhausting variable-frequency fan is set according to the scale of the number of microalgae to ensure that the flow rate of the smoke is basically constant. According to the frequency of the frequency conversion fan, that is, the flue gas flow, the sum of the opening degrees of the three electric regulating dampers 8 of high-temperature flue gas, low-temperature flue gas and air is calculated in equal proportions to ensure a reasonable flue gas flow. According to the temperature sensor and carbon dioxide concentration sensor of the connecting pipe between the gas mixing chamber and the incubator, the mixed flue gas temperature and CO2 concentration are monitored in real time, and the openings of the three electric dampers 8 are adjusted in real time to ensure that the flue gas temperature and CO2 concentration are within a suitable range. In different embodiments, when the air temperature is high, such as in summer, high temperature resistant microalgae can be selected, and the above-mentioned device can be used for microalgae carbon fixation.
