Description

一种VOCs气体处理装置及方法VOCs gas processing device and method 技术领域Technical field
本发明属于废气处理技术领域，具体涉及一种VOCs气体处理装置及方法。The invention belongs to the technical field of waste gas treatment, and in particular relates to a VOCs gas treatment device and method.
背景技术Background technique
挥发性有机化合物(volatile organic compounds，VOCs)是一种在室内和户外环境中很常见的污染物种类，主要有烃类(烷烃、芳烃、烯烃)，及烃类的衍生物(卤代烃、醛类、酮类、醇类、含N/S原子结构)等。机动车排放、建筑材料和装修、化工和石化废气、印刷和涂装工艺、餐饮油烟等被认为是环境中气态VOCs的主要来源。Volatile organic compounds (VOCs) are a kind of pollutants that are very common in indoor and outdoor environments. They mainly include hydrocarbons (alkanes, aromatics, olefins), and hydrocarbon derivatives (halogenated hydrocarbons, Aldehydes, ketones, alcohols, structures containing N/S atoms), etc. Motor vehicle emissions, building materials and decoration, chemical and petrochemical waste gas, printing and coating processes, and catering oil fume are considered to be the main sources of gaseous VOCs in the environment.
VOCs能够直接危害人类身体、影响人体健康状况的物质，它不仅对人的视觉、嗅觉和呼吸等***的器官有刺激作用，而且还会对心脏、肺等器官及神经***有伤害。另，VOCs可以与大气环境中的其他污染物反应，导致局部区域或全球性的环境问题，如在阳光(紫外光)作用下，VOCs可与NOx发生光化学反应形成细小的悬浮颗粒物和光化学烟雾，危害身体健康和农作物减产。VOCs are substances that can directly harm the human body and affect the health of the human body. They not only have a stimulating effect on human vision, smell, and respiratory systems, but also damage the heart, lungs and other organs and the nervous system. In addition, VOCs can react with other pollutants in the atmospheric environment, causing local or global environmental problems. For example, under the action of sunlight (ultraviolet light), VOCs can react photochemically with NOx to form fine suspended particles and photochemical smog. Harm to health and reduce crop production.
鉴于VOCs来源途径较多，排放量逐年增长，且VOCs组成结构极为复杂，开发有效降低VOCs排放的方法一直是行业研究的热点和难点。减少大气中VOCs的排放量，可以从排放的源头进行控制，或者对排放的末端进行综合治理。In view of the fact that there are many sources of VOCs, emissions are increasing year by year, and the composition of VOCs is extremely complex, the development of effective methods to reduce VOCs emissions has always been a hot and difficult point in industry research. To reduce the emission of VOCs in the atmosphere, it can be controlled from the source of the emission, or the end of the emission can be comprehensively treated.
对于高浓度的VOCs(大于5000mg/m 3)，适合进行回收并循环利用，有吸附法、吸收法、膜分离法等，其中物理吸附方法仅仅是将VOCs由气态形式转换为吸附态，吸附态的VOCs有机物尚需要进一步处理，而且吸附剂要经过反复再生过程。 For high-concentration VOCs (greater than 5000mg/m 3 ), it is suitable for recovery and recycling. There are adsorption method, absorption method, membrane separation method, etc. The physical adsorption method only converts VOCs from gaseous form to adsorbed state. The organic matter of VOCs needs further treatment, and the adsorbent has to undergo repeated regeneration processes.
对于中低浓度的VOCs常采用分子降解技术进行控制，主要有催化燃烧法、光催化法、低温等离子体法、光分解法、光催化氧化法等。其中，催化燃烧技术受限于高价格的金属催化剂、过多的能量消耗、催化剂中毒失活及高温下VOCs的易燃易爆的特性。光催化氧化技术是一种在室温下即可以实现低浓度VOCs分解的方法，被认为是一种有前景的处理工艺，但是其同样受限于催化剂的失活、电子对孔穴的再生等，同时，光催化氧化技术在反应开始可以达到较高的VOCs脱除效率，但反应过程中会在光催化剂表面形成光催化氧化中间体沉积物，导致光催化剂的催化活性降低。For low and medium concentrations of VOCs, molecular degradation technology is often used to control, mainly including catalytic combustion method, photocatalysis method, low temperature plasma method, photolysis method, photocatalytic oxidation method, etc. Among them, catalytic combustion technology is limited by high-priced metal catalysts, excessive energy consumption, catalyst poisoning and deactivation, and the flammable and explosive characteristics of VOCs at high temperatures. The photocatalytic oxidation technology is a method that can achieve the decomposition of low-concentration VOCs at room temperature. It is considered a promising treatment process, but it is also limited by the deactivation of the catalyst and the regeneration of holes by electrons. The photocatalytic oxidation technology can achieve high VOCs removal efficiency at the beginning of the reaction, but during the reaction process, photocatalytic oxidation intermediate deposits will be formed on the surface of the photocatalyst, resulting in a decrease in the catalytic activity of the photocatalyst.
紫外光(UV)降解VOCs技术是一种消除VOCs的简单方法，同时UV光降解技术不使用催化剂，具有较低的成本及可操作性，引起行业的关注。UV光降解VOCs有两个反应途径：一个反应途径是光分解反应，也可以称作光离解，其中典型的技术是UV灯管，由于短波长紫外线光子能量高于大多数污染物质分子内部化学键的键能，UV灯发出的185nm波长紫外光，其具有较高的能量(6.7eV)，可以被用来破坏并分解各种VOCs的化 学键结构，包括苯、甲苯、二甲苯等较难处理的有机分子结构；另一个反应途径是光氧化反应，185nm波长的紫外光，其产生的高能光子可以活化O 2和H 2O水蒸汽分子，产生大量具有强氧化性的活性自由基，如O(1D)、O(3P)、羟基自由基(*OH)、O 3等，可以继续氧化分解VOCs分子及其新生成的中间体小分子，从而起到降低污染物浓度的作用。 Ultraviolet (UV) degradation of VOCs technology is a simple method to eliminate VOCs. At the same time, UV degradation technology does not use catalysts, has lower cost and operability, and has attracted the attention of the industry. There are two reaction pathways for UV photodegradation of VOCs: One reaction pathway is photolysis reaction, which can also be called photodissociation. The typical technology is UV lamp, because the energy of short-wavelength ultraviolet photons is higher than that of chemical bonds in most pollutant molecules. Bond energy, the 185nm wavelength ultraviolet light emitted by the UV lamp has a higher energy (6.7eV), which can be used to destroy and decompose the chemical bond structure of various VOCs, including benzene, toluene, xylene and other difficult organic Molecular structure; another reaction pathway is the photooxidation reaction. The high-energy photons produced by ultraviolet light with a wavelength of 185nm can activate O 2 and H 2 O water vapor molecules to produce a large number of active free radicals with strong oxidizing properties, such as O(1D ), O(3P), hydroxyl radicals (*OH), O 3, etc., can continue to oxidize and decompose VOCs molecules and their newly generated intermediate small molecules, thereby reducing the concentration of pollutants.
在实际工程案例中发现，采用UV光解技术处理VOCs的过程中，光降解与光聚合反应同时发生，光降解可生成无害化CO 2与H 2O，而光聚合反应的产物为高分子聚合物，表现为粉尘颗粒(大分子量的有机固体颗粒物)，直接排放会对环境造成二次污染。但是，现有使用光解技术处理VOCs的工艺路线中，只检测VOCs的浓度变化，未考虑聚合反应的颗粒物产物，颗粒物作为光解技术的一种产物，若不对其进行截留收集，任其排放进入大气，对环境造成粉尘超标危害。 In the actual engineering case, it is found that in the process of using UV photolysis technology to treat VOCs, photodegradation and photopolymerization reaction occur simultaneously. Photodegradation can generate harmless CO 2 and H 2 O, and the product of photopolymerization reaction is polymer Polymers, which appear as dust particles (large molecular weight organic solid particles), directly discharged will cause secondary pollution to the environment. However, in the existing process route of using photolysis technology to treat VOCs, only the change in the concentration of VOCs is detected, and the particulate product of the polymerization reaction is not considered. As a product of photolysis technology, particulate matter is a product of photolysis technology. If it is not intercepted and collected, let it be discharged.

于本发明某些实施例中，所述UV处理+电场除尘结合净化VOCs气体所取得的技术 效果如下：In some embodiments of the present invention, the technical effects achieved by the combination of UV treatment + electric field dust removal and purification of VOCs gas are as follows:
本申请发明人研究发现，含有VOCs的气体经UV照射处理后的产物不仅仅是CO 2和H 2O，还存在大分子量的纳米级固体颗粒物，例如，本申请发明人通过大量实验数据证实：UV处理VOCs后的产物中PM2.5含量比UV照射前增多，UV处理产物中纳米级颗粒物大幅度增加，其中，粒径为23nm固体颗粒物的PN值增幅超过1倍，因此若将UV照射处理后产物直接排放，会造成二次污染。所以，UV处理含有VOCs的气体技术工艺中需要考虑脱除纳米固体颗粒物。但是现有技术没有发现脱除UV照射处理后的产物中纳米颗粒的相关研究，尤其是50nm以下的颗粒，特别是23nm的颗粒。本申请发明人发现他们发明的电场除尘***能有效脱除UV照射处理后产物中的纳米颗粒，尤其是50nm以下的颗粒，特别是23nm的颗粒。其中，23nm颗粒物的脱除效率达到99.99％以上，有效地避免了二次污染。 The inventors of the present application have discovered that the products of the gas containing VOCs after UV irradiation are not only CO 2 and H 2 O, but also large-molecular-weight nano-scale solid particles. For example, the inventors of the present application have confirmed through a large amount of experimental data: The content of PM2.5 in the product after UV treatment of VOCs is more than that before UV irradiation, and the nano-particles in the UV treatment product are greatly increased. Among them, the PN value of solid particles with a particle size of 23nm has increased by more than 1 times. Therefore, if the UV treatment is The subsequent products are directly discharged, which will cause secondary pollution. Therefore, the removal of nano-solid particles needs to be considered in the UV treatment of gas containing VOCs. However, the prior art has not found any relevant research on removing the nanoparticles in the product after UV irradiation, especially the particles below 50nm, especially the 23nm particles. The inventors of the present application found that the electric field dust removal system they invented can effectively remove nanoparticles in the product after UV irradiation treatment, especially particles below 50nm, especially 23nm particles. Among them, the removal efficiency of 23nm particles reaches more than 99.99%, effectively avoiding secondary pollution.
于本发明的一实施例中，所述吸附净化技术起到如下作用：In an embodiment of the present invention, the adsorption purification technology has the following functions:
第一：在紫外线处理阶段UV光不能将气体中VOCs完全处理为CO 2和H 2O，会产生中间产物，也不能降解所有的VOCs成分，在吸附装置中H 2O、UV光照的产物例如O 3、OH -、中间产物及未来得及降解的VOCs组分被吸附和集聚，被吸附在吸附材料孔道中的UV中间产物及未来得及降解的VOCs组分在O 3、OH -等强氧化剂作用下进一步分解成CO 2和H 2O，从吸附材料孔道内脱附，对UV光照处理VOCs起到辅助作用，同时实现在线脱附，避免吸附剂失效，确保吸附剂可重复使用，提高了VOCs处理效率。 First: In the ultraviolet treatment stage, UV light cannot completely process VOCs in the gas into CO 2 and H 2 O, will produce intermediate products, and cannot degrade all VOCs components. In the adsorption device, the products of H 2 O and UV light, such as O 3, OH -, and the intermediate product is not enough time to degradation and agglomeration VOCs are adsorbed component is adsorbed on the adsorbent material in the pores of the intermediate product and not enough time to UV degradation of the VOCs component O 3, OH - and other strong oxidants It further decomposes into CO 2 and H 2 O, desorbs from the pores of the adsorbent material, and assists the UV light treatment of VOCs. At the same time, it realizes online desorption to avoid adsorbent failure, ensure that the adsorbent can be reused, and increase VOCs. Processing efficiency.
第二：经济方面，实际应用操作中，VOCs释放量不是恒定的，以喷漆为例，喷漆过程中释放的VOCs浓度是波动的，当VOCs浓度很高时，UV光照不能完全降解VOCs，剩余的VOCs(在紫外线净化阶段内未被UV降解的VOCs)被吸附于吸附材料中存储起来，并被聚集浓缩，在UV光照产物O 3、OH -等强氧化剂作用下进一步再次被氧化分解；当VOCs浓度很低时，紫外线装置产生的强氧化离子羟基自由基(*OH)进入吸附装置对存储在吸附材料中的VOCs进一步催化成CO 2和H 2O。这就提高了VOCs气体处理效率，节约了能耗，也可实现VOCs气体处理设备小型化。 Second: In terms of economy, the amount of VOCs released is not constant in actual application operations. Take painting as an example. The concentration of VOCs released during the painting process fluctuates. When the concentration of VOCs is high, UV light cannot completely degrade VOCs, and the remaining VOCs (VOCs that have not been degraded by UV during the ultraviolet purification stage) are adsorbed and stored in the adsorption material, and are aggregated and concentrated, and are further oxidized and decomposed again under the action of strong oxidants such as O 3 , OH - and other products of UV light; when VOCs When the concentration is very low, the strong oxidizing ion hydroxyl radical (*OH) produced by the ultraviolet device enters the adsorption device to further catalyze the VOCs stored in the adsorption material into CO 2 and H 2 O. This improves the efficiency of VOCs gas treatment, saves energy consumption, and can also realize the miniaturization of VOCs gas treatment equipment.
第三：吸附材料可吸附光解产生的臭氧，吸附的臭氧使聚集在吸附材料中的VOCs被氧化，使得O 3得到充分利用，同时避免了臭氧造成的二次污染。 Third: The adsorption material can absorb the ozone produced by photolysis. The adsorbed ozone oxidizes the VOCs accumulated in the adsorption material, so that O 3 can be fully utilized, and the secondary pollution caused by ozone can be avoided.
于本发明的一实施例中，所述紫外线净化与吸附净化的结合提高了UV净化VOCs气体的效率，节约了能耗，使得VOCs气体处理装置小型化。In an embodiment of the present invention, the combination of ultraviolet purification and adsorption purification improves the efficiency of UV purification of VOCs gas, saves energy consumption, and makes the VOCs gas treatment device miniaturized.

In an embodiment of the present invention, the insulating mechanism includes insulating ceramic pillars. The design of the first anode part is mainly to protect the insulating ceramic pillars from being polluted by the particles in the gas.

于本发明一实施例中电场阳极和电场阴极分别与电源的两个电极电性连接。加载在电场阳极和电场阴极上的电压需选择适当的电压等级，具体选择何种电压等级取决于电场装置的体积、耐温、容尘率等。例如，电压从1kv至50kv；设计时首先考虑耐温条件，极间距与温度的参数：1MM<30度，积尘面积大于0.1平方/千立方米/小时，电场长度大于单管内切圆的5倍，控制电场气流流速小于9米/秒。于本发明一实施例中电场阳极由第一中空阳极管构成、并呈蜂窝状。第一中空阳极管端口的形状可以为圆形或多边形。于本发明一 实施例中第一中空阳极管的管内切圆取值范围在5-400mm，对应电压在0.1-120kv之间，第一中空阳极管对应电流在0.1-30A之间；不同的内切圆对应不同的电晕电压，约为1KV/1MM。In an embodiment of the present invention, the electric field anode and the electric field cathode are respectively electrically connected to the two electrodes of the power supply. The voltage applied to the electric field anode and the electric field cathode needs to select an appropriate voltage level. The specific voltage level selected depends on the volume, temperature resistance, and dust holding rate of the electric field device. For example, the voltage is from 1kv to 50kv; first consider the temperature resistance conditions in the design, the parameters of the pole spacing and temperature: 1MM<30 degrees, the dust area is greater than 0.1 square / thousand cubic meters / hour, and the electric field length is greater than 5 of the inscribed circle of a single tube The air flow velocity of the control electric field is less than 9 m/s. In an embodiment of the present invention, the electric field anode is composed of a first hollow anode tube and has a honeycomb shape.

本发明的发明人研究发现，现有电场装置去除效率差、能耗高的缺点是由电场耦合引起的。本发明通过减小电场耦合次数，可以显著减小电场装置的尺寸(即体积)。比如，本发明提供的电离除尘装置的尺寸约为现有电离除尘装置尺寸的五分之一。原因是，为了获得可接受的颗粒去除率，现有电离除尘装置中将气体流速设为1m/s左右，而本发明在将气体流速提高到6m/s的情况下，仍能获得较高的颗粒去除率。当处理一给定流量的气体时，随着气体速度的提高，电场装置的尺寸可以减小。The inventor of the present invention has discovered through research that the disadvantages of poor removal efficiency and high energy consumption of existing electric field devices are caused by electric field coupling. The present invention can significantly reduce the size (namely volume) of the electric field device by reducing the number of electric field couplings. For example, the size of the ionization dust removal device provided by the present invention is about one-fifth of the size of the existing ionization dust removal device. The reason is that in order to obtain an acceptable particle removal rate, the gas flow rate in the existing ionization dust removal device is set to about 1m/s, and the present invention can still obtain a higher gas flow rate when the gas flow rate is increased to 6m/s. Particle removal rate. When processing a given flow of gas, as the gas velocity increases, the size of the electric field device can be reduced.
另外，本发明可以显著提高颗粒去除效率。例如，在气体流速为1m/s左右时，现有技术电场装置可以去除发动机排气中大约70％的颗粒物，但是本发明可以去除大约99％的颗粒物，即使在气体流速为6m/s时。In addition, the present invention can significantly improve the particle removal efficiency. For example, when the gas flow rate is about 1m/s, the prior art electric field device can remove about 70% of the particulate matter in the engine exhaust, but the present invention can remove about 99% of the particulate matter, even when the gas flow rate is 6m/s.
由于发明人发现了电场耦合的作用，并且找到了减少电场耦合次数的方法，本发明获得了上述预料不到的结果。Since the inventor discovered the effect of electric field coupling and found a method to reduce the number of times of electric field coupling, the present invention achieved the above unexpected results.
本发明提供的减少电场耦合次数的方法如下：The method for reducing the number of electric field coupling provided by the present invention is as follows:
于本发明一实施例中电场阴极和电场阳极之间采用非对称结构。在对称电场中极性粒子受到一个相同大小而方向相反的作用力，极性粒子在电场中往复运动；在非对称电场中，极性粒子受到两个大小不同的作用力，极性粒子向作用力大的方向移动，可以减少耦合。In an embodiment of the present invention, an asymmetric structure is adopted between the electric field cathode and the electric field anode.

In order to reduce the electric field coupling of the ionization dust removal electric field, in an embodiment of the present invention, the method for reducing electric field coupling includes the following steps: selecting the ratio of the dust collection area of the electric field anode to the discharge area of the electric field cathode so that the number of electric field couplings is ≤3. In an embodiment of the present invention, the ratio of the dust collecting area of the electric field anode to the discharge area of the electric field cathode may be: 1.667:1 to 1680:1; 3.334:1 to 13.34:1; 6.67:1-56.67:1; 13.34: 1-28.33:1. This embodiment selects the dust collecting area of the electric field anode with a relatively large area and the discharge area of the relatively small electric field cathode. The specific selection of the above area ratio can reduce the discharge area of the electric field cathode, reduce the suction force, and expand the dust collecting area of the electric field anode. , Expand the suction, that is, the asymmetric electrode suction between the electric field cathode and the electric field anode will cause the charged dust to fall on the dust collecting surface of the electric field anode. Although the polarity is changed, it can no longer be sucked away by the electric field cathode, and the electric field coupling is reduced. Achieve electric field coupling times ≤ 3. That is, when the number of electric field couplings is less than or equal to 3, the electric field has low energy consumption, which can reduce the coupling consumption of aerosol, water mist, oil mist, and loose smooth particles in the gas by the electric field, and save 30-50% of the electric energy of the electric field. The dust collection area refers to the area of the working surface of the electric field anode. For example, if the electric field anode is a hollow regular hexagon tube, the dust collection area is the inner surface area of the hollow regular hexagon tube, and the dust collection area is also called the dust accumulation area. The discharge area refers to the area of the working surface of the electric field cathode. For example, if the electric field cathode is rod-shaped, the discharge area is the rod-shaped outer surface area.

如图6所示，本实施例中电场阳极5082呈管状，电场阴极5081呈棒状，电场阴极5081穿设在电场阳极5082中。同时本实施例中上述辅助电极5083也呈管状，辅助电极5083与电场阳极5082构成阳极管5084。阳极管5084的前端与电场阴极5081齐平，阳极管5084的后端向后超出了电场阴极5081的后端，该阳极管5084相比于电场阴极5081向后超出的部分为上述辅助电极5083。即本实施例中电场阳极5082和电场阴极5081的长度相同，电场阳极5082和电场阴极5081在前后方向上位置相对；辅助电极5083位于电场阳极5082和电场阴极5081的后方。这样，辅助电极5083与电场阴极5081之间形成辅助电场，该辅助电场给电场阳极5082和电场阴极5081之间带负电荷的氧离子流施加向后的力。当含有待处理物质的气体由前向后流入阳极管5084，带负电荷的氧离子在向电场阳极5082且向后移动过程中将与待处理物质相结合，由于氧离子具有向后的移动速度，氧离子在与待处理物质相结合时，两者间不会产生较强的碰撞，从而避免因较强碰撞而造成较大的能量消耗，使得氧离子易于与待处理物质相结合，并使得气体中待处理物质的荷电效率更高，进而在电场阳极5082及阳极管5084的作用下，能将更多的待处理物质收集起来，保证本电场装置的除尘效率更高。As shown in FIG. 6, in this embodiment, the electric field anode 5082 is tubular, the electric field cathode 5081 is rod-shaped, and the electric field cathode 5081 penetrates the electric field anode 5082. At the same time, the auxiliary electrode 5083 in this embodiment is also tubular, and the auxiliary electrode 5083 and the electric field anode 5082 constitute an anode tube 5084. The front end of the anode tube 5084 is flush with the electric field cathode 5081, and the rear end of the anode tube 5084 exceeds the rear end of the electric field cathode 5081 backward. Compared with the electric field cathode 5081, the part of the anode tube 5084 that extends backward is the auxiliary electrode 5083. That is, in this embodiment, the electric field anode 5082 and the electric field cathode 5081 have the same length, and the electric field anode 5082 and the electric field cathode 5081 are opposite in the front and rear direction; the auxiliary electrode 5083 is located behind the electric field anode 5082 and the electric field cathode 5081. In this way, an auxiliary electric field is formed between the auxiliary electrode 5083 and the electric field cathode 5081, and the auxiliary electric field applies a backward force to the negatively charged oxygen ion flow between the electric field anode 5082 and the electric field cathode 5081. When the gas containing the substance to be treated flows into the anode tube 5084 from front to back, the negatively charged oxygen ions will combine with the substance to be treated in the process of moving to the electric field anode 5082 and backward, because the oxygen ions have a backward moving speed When the oxygen ions are combined with the substance to be treated, there will be no strong collision between the two, thereby avoiding large energy consumption due to the strong collision, making the oxygen ions easy to combine with the substance to be treated, and making The charging efficiency of the substances to be treated in the gas is higher, and furthermore, under the action of the electric field anode 5082 and the anode tube 5084, more substances to be treated can be collected, ensuring higher dust removal efficiency of the electric field device.
另外，如图6所示，本实施例中阳极管5084的后端与电场阴极5081的后端之间具有夹角α，且0°＜α≤125°、或45°≤α≤125°、或60°≤α≤100°、或α＝90°。In addition, as shown in FIG. 6, there is an angle α between the rear end of the anode tube 5084 and the rear end of the electric field cathode 5081 in this embodiment, and 0°<α≤125°, or 45°≤α≤125°, Or 60°≤α≤100°, or α=90°.
本实施例中电场阳极5082、辅助电极5083、及电场阴极5081构成除尘单元，且该除尘单元有多个，以利用多个除尘单元有效提高本电场装置的除尘效率。In this embodiment, the electric field anode 5082, the auxiliary electrode 5083, and the electric field cathode 5081 constitute a dust removal unit, and there are multiple dust removal units to effectively improve the dust removal efficiency of the electric field device by using multiple dust removal units.

本实施例中直流电源具体可为直流高压电源。上述电场阴极5081和电场阳极5082之间形成放电电场，该放电电场是一种静电场。在无上述辅助电极5083的情况下，电场阴极5081和电场阳极5082之间电场中离子流沿垂直于电极方向，且在两电极间折返流动，并导致离子在电极间来回折返消耗。为此，本实施例利用辅助电极5083使电极相对位置错开，形成电场阳极5082和电场阴极5081间相对不平衡，这个不平衡会使电场中离子流发生偏转。本电场装置利用辅助电极5083形成能使离子流具有方向性的电场。The DC power supply in this embodiment may specifically be a DC high-voltage power supply. A discharge electric field is formed between the electric field cathode 5081 and the electric field anode 5082, and the discharge electric field is an electrostatic field. Without the auxiliary electrode 5083, the ions flow in the electric field between the electric field cathode 5081 and the electric field anode 5082 along the direction perpendicular to the electrodes, and flow back and forth between the two electrodes, causing the ions to be folded back and forth between the electrodes for consumption. For this reason, in this embodiment, the auxiliary electrode 5083 is used to stagger the relative positions of the electrodes to form a relative imbalance between the electric field anode 5082 and the electric field cathode 5081. This imbalance will deflect the ion current in the electric field. In this electric field device, an auxiliary electrode 5083 is used to form an electric field capable of directional ion flow.

In this way, an auxiliary electric field is formed between the auxiliary electrode and the electric field anode. The auxiliary electric field applies a backward force to the negatively charged oxygen ion flow between the electric field anode and the electric field cathode, so that the negatively charged oxygen ions between the electric field anode and the electric field cathode The flow has a backward movement speed. When the gas containing the substance to be treated flows into the tubular electric field anode from front to back, the negatively charged oxygen ions will be combined with the substance to be treated during the process of moving to the electric field anode and backward, because oxygen ions have a backward moving speed When the oxygen ions are combined with the substance to be treated, there will be no strong collision between the two, thereby avoiding large energy consumption due to the strong collision, making the oxygen ions easy to combine with the substance to be treated, and making The charging efficiency of the substances to be treated in the gas is higher, and more substances to be treated can be collected under the action of the anode of the electric field, which ensures that the dust removal efficiency of the electric field device is higher.

当接通紫外线装置中紫外灯电源后(电场装置暂时不打开)，电场装置的装置出口处VOCs浓度及VOCs脱除率随时间的变化曲线如图10所示，其中A显示为电场装置出口 VOCs浓度(即紫外线装置出气口处VOCs浓度)，B显示为VOCs脱除效率。由图10可知，当紫外灯处理80s内VOCs的浓度值基本维持在320mg/m 3的浓度值不变化，80s后VOCs浓度迅速下降；处理440s左右，VOCs浓度值下降至201mg/m 3，脱除效率高达37.1％左右。 When the power of the ultraviolet lamp in the ultraviolet device is turned on (the electric field device is temporarily not turned on), the VOCs concentration at the outlet of the electric field device and the VOCs removal rate with time are shown in Figure 10, where A shows the VOCs at the outlet of the electric field device Concentration (that is, the concentration of VOCs at the outlet of the ultraviolet device), B shows the VOCs removal efficiency. It can be seen from Fig. 10 that when the concentration of VOCs is basically maintained at 320mg/m 3 within 80s of UV lamp treatment, the concentration of VOCs drops rapidly after 80s; the concentration of VOCs drops to 201mg/m 3 after treatment for 440s. The removal efficiency is as high as 37.1%.

图11为电场装置的装置出口处CO 2浓度随处理时间的变化曲线，CO 2初始浓度为903.3mg/m 3，由图11可知，UV紫外灯开启后CO 2浓度迅速增加，当处理时间达到453s后，CO 2浓度达到1126mg/m 3，而后CO 2浓度在1135mg/m 3范围内保持相对稳定。可见，除尘电场的开启对CO 2的生成量影响不大。 Figure 11 is the change curve of CO 2 concentration at the outlet of the electric field device with treatment time. The initial CO 2 concentration is 903.3 mg/m 3. It can be seen from Figure 11 that the CO 2 concentration increases rapidly after the UV lamp is turned on. When the treatment time reaches After 453s, the CO 2 concentration reached 1126 mg/m 3 , and then the CO 2 concentration remained relatively stable within the range of 1135 mg/m 3 . It can be seen that the opening of the dust removal electric field has little effect on the amount of CO 2 produced.

3.1.2净化过程中各净化单元出口VOCs变化数据3.1.2 VOCs change data at the outlet of each purification unit during the purification process
3.1.2.1 VOCs浓度3.1.2.1 VOCs concentration
图14为净化低VOCs浓度时紫外线装置4进气口41、出气口42、吸附装置6出气口62处VOCs浓度随时间的变化曲线，其中，A显示为缓冲罐出口VOCs浓度，B显示为紫外线装置4出气口42处VOCs浓度，C显示为吸附装置6出气口62处VOCs浓度。由图14可知，从吸附装置6出气口62处VOCs浓度的变化曲线可知，组合净化试验刚开始时，0s-600s内吸附区出口VOCs浓度值稳定在6-9mg/m 3，这期间的组合净化效率达到98.5％。 Figure 14 shows the time-varying curve of VOCs concentration at the air inlet 41, air outlet 42, and outlet 62 of the ultraviolet device 4 when purifying low VOCs concentration, where A shows the VOCs concentration at the outlet of the buffer tank, and B shows ultraviolet The VOCs concentration at the outlet 42 of the device 4, C shows the VOCs concentration at the outlet 62 of the adsorption device 6. It can be seen from Figure 14 that the change curve of the VOCs concentration at the outlet 62 of the adsorption device 6 shows that at the beginning of the combined purification test, the VOCs concentration at the outlet of the adsorption zone within 0s-600s stabilized at 6-9mg/m 3 , the combination during this period The purification efficiency reaches 98.5%.
在800s(13min)左右，吸附装置6出气口62处VOCs浓度＝30mg/m 3(设定VOCs浓度值为原始浓度5％时，吸附剂穿透)，吸附剂穿透，穿透前，组合净化效率至少在95％ 以上； At about 800s (13min), the VOCs concentration at the outlet 62 of the adsorption device 6 = 30mg/m 3 (when the VOCs concentration is set to 5% of the original concentration, the adsorbent penetrates), the adsorbent penetrates, before penetration, combination The purification efficiency is at least 95%;
当组合净化时间超过穿透时间后，组合净化效率逐渐下降，7200s(2小时)时吸附装置6出气口62浓度上升至197mg/m 3，此时紫外线装置出气口浓度为219mg/m 3，即吸附净化前后的浓度基本相等，分子筛+活性炭组合吸附剂已经达到饱和失效，不能再起到吸附净化VOCs的作用，需要提前对饱和的吸附剂进行更换和VOCs脱附再生。 When the combined purification time exceeds the penetration time, the combined purification efficiency gradually decreases. At 7200s (2 hours), the concentration of the outlet 62 of the adsorption device 6 rises to 197mg/m 3 , at this time the concentration of the outlet of the ultraviolet device is 219mg/m 3 , that is The concentration before and after the adsorption purification is basically the same. The molecular sieve + activated carbon combined adsorbent has reached saturation and can no longer play the role of adsorbing and purifying VOCs. The saturated adsorbent needs to be replaced in advance and VOCs desorption regeneration.
整个组合净化过程，从净化开始至吸附装置内吸附剂饱和，共计7200s左右，从本试验数据统计可得，UV净化装置独自的VOCs净化效率基本保持在40.9％左右。The entire combined purification process, from the beginning of the purification to the saturation of the adsorbent in the adsorption device, totals about 7200 seconds. According to the statistics of this test, the VOCs purification efficiency of the UV purification device is basically maintained at about 40.9%.
3.1.2.2净化过程中各净化单元出口CO 2变化数据 3.1.2.2 Changes in CO 2 at the outlet of each purification unit during the purification process
图15为净化低VOCs浓度时紫外线装置进气口、出气口、吸附装置出口处CO 2浓度随时间的变化曲线，其中，A显示为缓冲罐出口处CO 2浓度，B显示为紫外线装置出气口处CO 2浓度，C显示为吸附装置出气口出处CO 2浓度。由图15可知，紫外线装置进气口处CO 2浓度整体保持在852mg/m 3的平均水平，当达到UV最大VOCs净化效率后，紫外线装置出气口处CO 2浓度基本维持在相对稳定的水平即1284mg/m 3，CO 2经UV净化后的新生成率稳定在50.7％左右。 Figure 15 shows the change curve of CO 2 concentration at the inlet, outlet and outlet of the ultraviolet device with time when purifying low VOCs concentration. A shows the CO 2 concentration at the outlet of the buffer tank and B shows the outlet of the ultraviolet device. at the CO 2 concentration, C is the display device of the source outlet concentration of CO 2 adsorption. It can be seen from Figure 15 that the CO 2 concentration at the inlet of the ultraviolet device is maintained at an average level of 852 mg/m 3. When the maximum UV VOCs purification efficiency is reached, the CO 2 concentration at the outlet of the ultraviolet device is basically maintained at a relatively stable level. 1284mg/m 3 , the new generation rate of CO 2 after UV purification is stable at about 50.7%.
吸附装置出口处CO 2浓度在360s后达到最大值1584mg/m 3，而后保持在一个相对稳定的水平即1472mg/m 3，即组合净化的CO 2新生成率稳定在72.8％左右。 The CO 2 concentration at the outlet of the adsorption device reached the maximum value of 1584 mg/m 3 after 360 seconds, and then remained at a relatively stable level of 1472 mg/m 3 , that is, the new CO 2 generation rate of the combined purification was stabilized at about 72.8%.
对比UV净化装置与吸附装置出口处CO 2的浓度与新生成率，可知，吸附装置的CO 2的浓度与新生成率依旧在大幅度增加，这是由于从UV单元出口的VOCs、O 3、H2O在进入吸附区后，可以吸附在分子筛和活性炭的外表面和孔道内表面，并继续发生VOCs的催化氧化分解生成CO 2，对废气中VOCs进行进一步净化。 UV contrast at the purge outlet means and the adsorption means and a newly generated CO concentration ratio of 2, it is found, the new generation of CO concentration and the adsorption device 2 is still a substantial increase in, since outlet VOCs from the UV unit, O 3, After H2O enters the adsorption zone, it can be adsorbed on the outer surface of molecular sieve and activated carbon and the inner surface of the pores, and the catalytic oxidation and decomposition of VOCs will continue to generate CO 2 to further purify the VOCs in the exhaust gas.
3.1.2.3组合净化开始和组合净化结束后PM 2.5数据对比3.1.2.3 PM 2.5 data comparison between the beginning of combined purification and after the end of combined purification
在正式组合净化实验开始之前，0.9m 3/h和614mg/m 3的VOCs气体中的PM2.5值为79μg/m 3，7200s净化实验结束后吸附装置出口气体中的PM2.5值上升到6096μg/m 3，PM2.5增加近77倍。 Before the start of the formal combined purification experiment, the PM2.5 value in the 0.9m 3 /h and 614mg/m 3 VOCs gas was 79 μg/m 3. After the 7200s purification experiment, the PM2.5 value in the outlet gas of the adsorption device rose to 6096μg/m 3 , PM2.5 increased nearly 77 times.
一方面说明VOCs在UV光分解和光氧化过程中不仅分解生成了CO 2，而且发生了光聚合反应，VOCs分子聚合生成了具有高分子量的有机颗粒物，分散在气体当中。 On the one hand, it shows that VOCs not only decompose to generate CO 2 in the process of UV photolysis and photooxidation, but also undergo photopolymerization. VOCs molecules polymerize to form organic particles with high molecular weight, which are dispersed in the gas.

A shows the VOCs concentration at the outlet of the buffer tank, and B shows the VOCs at the outlet of the ultraviolet device. Concentration, C shows the VOCs concentration at the outlet of the adsorption device. It can be seen from Figure 16 that from the change curve of the VOCs concentration C7 at the outlet of the adsorption device, it can be seen that at the beginning of the combined purification test, the VOCs concentration at the outlet of the adsorption zone within 0s-600s stabilized at 8-19mg/m 3. The combined purification during this period The efficiency reaches 98.3%.
在1020s左右，吸附区出口VOCs浓度＝55mg/m 3(设定VOCs浓度值为原始浓度5％时，吸附剂穿透)，吸附剂穿透，穿透前，组合净化效率至少在94.7％以上； At about 1020s, the VOCs concentration at the outlet of the adsorption zone = 55mg/m 3 (when the VOCs concentration is set to 5% of the original concentration, the adsorbent penetrates), the adsorbent penetrates, and the combined purification efficiency is at least 94.7% before penetration ；
当组合净化时间超过穿透时间后，组合净化效率逐渐下降，7200s(2小时)时吸附装置出气口处出口浓度上升至451mg/m 3，此时紫外线装置出口浓度C5为456mg/m 3，分子筛+活性炭组合吸附剂已经达到饱和失效，不能再起到吸附净化VOCs的作用，此时的组合净化效率已下降至41.1％，仅紫外线装置能起净化作用。 When the combined purification time exceeds the penetration time, the combined purification efficiency gradually decreases. At 7200s (2 hours), the outlet concentration at the outlet of the adsorption device rises to 451mg/m 3 , at this time the UV device outlet concentration C5 is 456mg/m 3 , molecular sieve +The activated carbon combined adsorbent has reached saturation and can no longer play the role of adsorbing and purifying VOCs. At this time, the combined purification efficiency has dropped to 41.1%, and only the ultraviolet device can perform purification.
整个组合净化过程，从净化开始至吸附装置内吸附剂饱和，共计7200s左右，从本试验数据统计可得，UV净化装置独自的VOCs净化效率基本保持在41.1％左右。The entire combined purification process, from the beginning of the purification to the saturation of the adsorbent in the adsorption device, takes about 7200 seconds. According to the statistics of this test, the VOCs purification efficiency of the UV purification device is basically maintained at about 41.1%.

A shows the CO 2 concentration at the outlet of the buffer tank, and B shows the outlet of the ultraviolet device at the CO 2 concentration, C is the display device of the source outlet concentration of CO 2 adsorption. It can be seen from Figure 17 that the CO 2 concentration at the inlet of the UV device remained at an average level of 882.5 mg/m 3 as a whole. When the maximum UV VOCs purification efficiency was reached, the CO 2 concentration at the outlet of the UV device was basically maintained at a relatively stable level. That is, 1531mg/m 3 , the new generation rate of CO2 after UV purification is stable at about 73.6%.
吸附装置出气口处CO 2浓度在360s后达到最大值1748mg/m 3，而后保持在一个相对稳定的水平即1679mg/m 3，即组合净化的CO 2新生成率稳定在90.3％左右。 The CO 2 concentration at the outlet of the adsorption device reached the maximum value of 1748 mg/m 3 after 360 seconds, and then remained at a relatively stable level of 1679 mg/m 3 , that is, the new CO 2 generation rate of the combined purification stabilized at about 90.3%.
对比紫外线装置与吸附装置出气口处CO 2的浓度与新生成率，可知，吸附装置的CO 2 浓度与新生成率依旧在大幅度增加，这是由于从紫外线装置出气口的VOCs、O 3、H 2O在进入吸附区后，可以吸附在分子筛和活性炭的外表面和孔道内表面，并继续发生VOCs的催化氧化分解生成CO 2，对气体中VOCs进行进一步净化。 Comparison means and ultraviolet adsorption device and the CO concentration at the outlet of a new generation of 2, can be seen, the concentration of CO 2 adsorption with the new generation of devices is still a substantial increase, due to the outlet of the device from the ultraviolet VOCs, O 3, After H 2 O enters the adsorption zone, it can be adsorbed on the outer surface of molecular sieve and activated carbon and the inner surface of the pores, and the catalytic oxidation and decomposition of VOCs will continue to generate CO 2 to further purify the VOCs in the gas.
