技术领域technical field
本实用新型属于静电除尘领域，尤其是指一种基于微波的炭磁孤岛静电除尘装置。The utility model belongs to the field of electrostatic dust removal, in particular to a microwave-based carbon magnetic isolated island electrostatic dust removal device.
背景技术Background technique
近来医学研究表明肺癌的发生呈上升趋势，特别是不吸烟者的肺癌发生率也同样呈上升趋势。已有文献报道这种情况的出现同PM2.5关系密切。PM2.5是指空气动力学直径小于2.5微米的颗粒，它能吸附各种有毒物质并直接进入人体下呼吸道。现在公认PM2.5是污染物之一。Recent medical research shows that the incidence of lung cancer is on the rise, especially the incidence of lung cancer among non-smokers is also on the rise. It has been reported in the literature that the occurrence of this situation is closely related to PM2.5. PM2.5 refers to particles with an aerodynamic diameter of less than 2.5 microns, which can absorb various toxic substances and directly enter the lower respiratory tract of the human body. It is now recognized that PM2.5 is one of the pollutants.
热电企业、供暖企业所使用的燃煤是PM2.5的重要来源之一，因而对这些企业排放物的治理是抑制PM2.5的重要手段。在众多的治理方法中静电是一种较为理想的方法。静电除尘主要是靠颗粒荷电，然后被吸附而脱除。尽管这是一种好的办法，可是对于微小颗粒的去除率还不能达到满意程度，这是因为动力学直径在1微米附近的颗粒很难荷电，因为颗粒带不上电荷，所以不能被电场极板吸附。为此在静电除尘的基础上又有滤料处理方式，即布袋方法同静电方法混合使用，但是布袋方式导致风阻大幅度增加，同时对于1微米附近颗粒处理效果也不理想。为了既能提升微细颗粒的去除率，又不大幅度的增大风阻，需要进一步采取措施。Coal combustion used by thermal power enterprises and heating enterprises is one of the important sources of PM2.5, so the control of emissions from these enterprises is an important means to suppress PM2.5. Among the many treatment methods, static electricity is an ideal method. Electrostatic precipitator mainly depends on particle charge, and then is removed by adsorption. Although this is a good method, the removal rate of tiny particles is still not satisfactory. This is because particles with a kinetic diameter of around 1 micron are difficult to charge, because the particles cannot be charged, so they cannot be charged by an electric field. Plate adsorption. For this reason, on the basis of electrostatic dust removal, there is a filter material treatment method, that is, the cloth bag method is used in combination with the electrostatic method, but the cloth bag method leads to a significant increase in wind resistance, and the treatment effect on particles near 1 micron is not ideal. In order to improve the removal rate of fine particles without greatly increasing the wind resistance, further measures need to be taken.
研究表明活性炭可以有效的去除微颗粒且有报道磁场对粒子形成的拉莫效应可以有助于提高微颗粒在静电场中的去除率。已有报道微波可以将增加微细颗粒的凝并作用，为此将三者一起用于本装置，以增加对微颗粒的去除率。Studies have shown that activated carbon can effectively remove microparticles and it has been reported that the Larmor effect formed by magnetic field on particles can help to improve the removal rate of microparticles in electrostatic field. It has been reported that microwaves can increase the coagulation of fine particles, so the three are used together in this device to increase the removal rate of fine particles.
本实用新型提出了一种基于微波的炭磁孤岛静电除尘装置，它可以有效地增加对微颗粒（气溶胶）的去除率。The utility model proposes a microwave-based carbon magnetic island electrostatic precipitator, which can effectively increase the removal rate of microparticles (aerosol).
发明内容Contents of the invention
为了既可以提升微颗粒的去除率又不大幅度的增加风阻,In order to improve the removal rate of fine particles without greatly increasing wind resistance,
本实用新型提出一种基于微波的炭磁孤岛静电除尘装置。The utility model proposes a microwave-based carbon magnetic isolated island electrostatic dust removal device.
本实用新型解决其技术问题所采用的技术方案是：本实用新型装置由烟道壁、高压柱状电极绝缘支架、绝缘支架接杆、高压筒状电极、筒状电极绝缘支架、炭磁孤岛、孤岛横支架、孤岛竖支架、风车风叶、风叶支架、高压柱状电极、微波发生器、横烟道、竖烟道组成，其特征是：圆柱形的微波发生器位于横烟道壁上且在竖烟道底端，球形的炭磁孤岛通过圆柱状的孤岛横支架、圆柱状的孤岛竖支架同风车风叶相连。The technical solution adopted by the utility model to solve its technical problems is: the utility model device is composed of a flue wall, a high-voltage columnar electrode insulating support, an insulating support rod, a high-voltage cylindrical electrode, a cylindrical electrode insulating support, a carbon magnetic island, and an isolated island. It is composed of horizontal bracket, island vertical bracket, windmill fan blade, fan blade bracket, high-voltage columnar electrode, microwave generator, horizontal flue, and vertical flue. Its characteristics are: the cylindrical microwave generator is located on the wall of the horizontal flue and At the bottom of the vertical flue, the spherical carbon magnetic island is connected to the windmill blades through the cylindrical island horizontal bracket and the cylindrical island vertical bracket.
炭磁孤岛由球形的绝缘网袋内装上活性碳块和永久磁铁磁块组成。高压柱状电极为圆柱形结构；高压筒状电极、烟道壁均为圆筒状结构。The carbon magnetic island is composed of activated carbon blocks and permanent magnets in a spherical insulating mesh bag. The high-voltage columnar electrode has a cylindrical structure; the high-voltage cylindrical electrode and the flue wall are both cylindrical in structure.
当烟尘进入烟道后，在引风机的作用下，经过预荷电处理的烟尘进入由高压线状电极和高压筒状电极组成的电场内，带电的颗粒将在电场力的作用下，向其带电极性相反的电极板运动，此时在风力的作用下，风车风叶将旋转。风车风叶将通过孤岛竖支架、孤岛横支架带动炭磁孤岛围绕高压柱状电极转动。由于活性碳块内的多孔结构，决定了其吸附特性，它可以很好的吸附周围的细微颗粒，而这些颗粒正好是难以荷电的微颗粒；同时，由于活性碳块极易在电场内感应带电，因而呈现出良好的电特性，有利于吸附微颗粒。由炭磁孤岛体积不大，所以对风阻影响不大。炭磁孤岛转动使得在其内部的磁铁块转动。永久磁铁磁块的转动形成了转动的磁场，微粒子会产生复杂的拉莫运动，使其停留在电场中的时间增长，有利于微颗粒的去除。When the soot enters the flue, under the action of the induced draft fan, the pre-charged soot enters the electric field composed of high-voltage linear electrodes and high-voltage cylindrical electrodes, and the charged particles will be charged to it under the action of the electric field force. The electrode plates with opposite polarities move, and at this time, under the action of wind force, the blades of the windmill will rotate. The blades of the windmill will drive the carbon magnetic island to rotate around the high-voltage columnar electrode through the vertical support of the island and the horizontal support of the island. Due to the porous structure in the activated carbon block, its adsorption characteristics are determined, it can well adsorb the surrounding fine particles, and these particles are just the fine particles that are difficult to charge; at the same time, because the activated carbon block is very easy to induce in the electric field Charged, thus showing good electrical characteristics, which is conducive to the adsorption of microparticles. Since the carbon magnetic island is small in size, it has little effect on wind resistance. The rotation of the carbon magnetic island makes the magnet block inside it rotate. The rotation of the permanent magnet block forms a rotating magnetic field, and the microparticles will produce complex Larmor motion, which will increase the time they stay in the electric field, which is beneficial to the removal of microparticles.
在引风机的作用下，烟尘进入圆柱横烟道，由水平的横烟道转入垂直的竖烟道。在横烟道和竖烟道的连接处的下方，安装有一台微波发生器。微波发生器的波导向上。因而进入竖烟道的粉尘粒子会受到微波的作用。Under the action of the induced draft fan, the dust enters the cylindrical horizontal flue, and turns from the horizontal horizontal flue to the vertical vertical flue. Below the junction of the horizontal flue and the vertical flue, a microwave generator is installed. The waveguide of the microwave generator is upward. Therefore, the dust particles entering the vertical flue will be affected by microwaves.
微波使微粒子产生振荡，微粒子的能量增加，使其易于吸附电子，有利于微颗粒的凝并；同时，微波也有利于电晕的形成，可以电离出更多的自由电子和正电荷。二者的共同作用下，使粉尘微粒的去除率上升。Microwaves cause microparticles to oscillate, and the energy of microparticles increases, making it easy to absorb electrons, which is beneficial to the coagulation of microparticles; at the same time, microwaves are also conducive to the formation of corona, which can ionize more free electrons and positive charges. Under the joint action of the two, the removal rate of dust particles is increased.
本实用新型的有益效果是，在风阻增加不大的前提下，能够提升微颗粒去除率，以达到除尘的最佳效果。它主要用于静电除尘领域。The beneficial effect of the utility model is that, under the premise of little increase in wind resistance, the removal rate of micro particles can be improved, so as to achieve the best effect of dust removal. It is mainly used in the field of electrostatic dust removal.
