Description

一种利用微波能处理污水的设备技术领域 Device for treating sewage by using microwave energy

本发明涉及污水处理设备技术领域，特别涉及一种利用微波能处理污水的设备。背景技术 The invention relates to the technical field of sewage treatment equipment, in particular to an apparatus for treating sewage by using microwave energy. Background technique

随着人类社会生产和经济活动的加强，人类的不合理开发利用导致环境质量不断恶化。水体污染、水质恶化加剧了全球水资源短缺局面。为了缓解环境质量恶化和用水紧张问题，长久以来，人们一直致力于污水处理技术的开发研究。发展至今，污水处理技术可大致分为物理法、化学法、物化法和生化法四类。然而这些处理方法都有一定的局限性，在应用条件和处理效果上存在很大的缺陷，如目前占市场主导地位的、技术成熟的污水生化处理法（如活性污泥法、氧化沟等）就有占地面积大、投资大、施工期长、水质水量波动适应性差、运行管理费用高、易受气候条件限制等缺点。严重限制污水处理事业的发展。针对于此，人们提出了一种新型污水处理技术——微波污水处理技术。 With the strengthening of human social production and economic activities, the irrational development and utilization of human beings has led to the deterioration of environmental quality. Water pollution and deterioration of water quality have increased the global water shortage. In order to alleviate the deterioration of environmental quality and water stress, people have been working on the development of sewage treatment technology for a long time. Up to now, sewage treatment technology can be broadly divided into physical, chemical, physicochemical and biochemical methods. However, these treatment methods have certain limitations, and there are great defects in application conditions and treatment effects, such as the current market-dominant, technically mature sewage biochemical treatment methods (such as activated sludge method, oxidation ditch, etc.) It has the disadvantages of large land area, large investment, long construction period, poor adaptability of water quality and water fluctuation, high operation and management costs, and limited weather conditions. Seriously limit the development of sewage treatment. In response to this, a new type of sewage treatment technology, microwave wastewater treatment technology, has been proposed.

微波污水处理技术改变了传统的污水处理方式，使污水处理方法变得更加简单有效。其原理简述如下：污水中的极性分子 (含占污水绝大部分的水分子)在髙速交变的微波电磁场中产生剧烈取向运动（如使用频率 2450MHz的微波，该取向运动是以 24. 5亿次 /秒的频率在高速进行)，各极性污染物分子、非极性污染物分子在此剧烈的大运动体系中都主动或被动地高速运动，都或多或少地将微波能转换为污染物分子的内能，使其活化能降低而积极参与各种物理、化学反应，使原本不能进行的反应变得可以进行，使原本反应缓慢的反应变得快速，甚至可使原本不具备催化功能的物质变得对某些反应具有了催化功能等等，还可使污水中的细菌、病原体其空间结构发生变化或破坏，蛋白质变性，从而失去生物活性，也可改变其生物性排列聚合状态及其运动规律，而且微波场感应的离子流，会影响细胞膜附近的电荷分布，导致膜的屏障作用受到损伤，影响 Na-K 泵的功能，产生膜功能障碍，从而干扰或破坏细胞的正常新陈代谢功能，导致细菌生长抑制、停止或死亡，再则细胞中的核糖核酸（RNA)和脱氧核糖核酸 (DNA)在微波场力作用下可导致键的松驰、断裂或重组。诱发基因突变或染色体畸变，影响其生物活性的改变，延缓或中断细胞的稳定遗传和增殖。从而使污水得以净化。 Microwave wastewater treatment technology has changed the traditional sewage treatment method, making the sewage treatment method simpler and more effective. The principle is briefly described as follows: The polar molecules in the sewage (including the majority of the water molecules in the sewage) produce intense orientation motion in the microwave electromagnetic field with alternating idling (such as the use of microwaves with a frequency of 2450 MHz, the orientation motion is 24 500 million times / sec. at high speed), each polar pollutant molecule, non-polar pollutant molecules in this violent large motion system are active or passive high-speed motion, more or less microwave It can be converted into the internal energy of the pollutant molecule, so that its activation energy is reduced and it actively participates in various physical and chemical reactions, so that the reaction which could not be carried out can be made, and the reaction which is slow in the original reaction becomes fast, and even the original Substances that do not have catalytic function become catalytic functions for certain reactions, etc., and can also change or destroy the spatial structure of bacteria and pathogens in sewage, denature proteins, thereby losing biological activity, and also changing their biological properties. Arrange the polymerization state and its motion law, and the ion current induced by the microwave field will affect the charge distribution near the cell membrane, resulting in the screen of the membrane. Damage to the function, affecting the function of the Na-K pump, causing membrane dysfunction, thereby interfering with or disrupting the normal metabolic function of the cell, resulting in inhibition, cessation or death of bacterial growth, and then ribonucleic acid (RNA) and deoxyribonucleic acid in the cell (DNA) can cause relaxation, fragmentation or recombination of bonds under the action of microwave field forces. Inducing gene mutations or chromosomal aberrations affects changes in their biological activity, delaying or disrupting the stable inheritance and proliferation of cells. Thereby the sewage is purified.

决方案，如中国专利公开发表的 CN1231213A 、 CN101143737A 、 CN201033739Y 、 CN201024097Y等等具有一定的代表性，但都有一个共同点，即 "微波污水处理器"是微波污水处理***必不可少的、共有技术特征的设备，是微波污水处理***的关键。微波污水处理器是由波源（含输出功率可调的控制***）、微波谐振腔'和徼波污水处理器芯三大部分组成。 The solution, such as CN1231213A, CN101143737A, CN201033739Y, CN201024097Y, etc., published in Chinese patents has certain representativeness, but all have one thing in common, that is, "microwave sewage processor" is micro The indispensable equipment with common technical features of the wave sewage treatment system is the key to the microwave wastewater treatment system. The microwave sewage processor is composed of three parts: wave source (control system with adjustable output power), microwave resonator chamber and chopper sewage processor core.

其中大部分专利文献习惯将技术早已十分成熟的微波波源（含微波功率可调的控制部分）以及已经标准化的微波短距离输送元件（波导管及法兰）加以大篇幅描述，其实这是成熟的、共有的技术特征，人们只需拿来用即可。 Most of the patent documents are used to describe the microwave wave source (the control part with adjustable microwave power) and the standardized microwave short-distance transmission element (waveguide and flange), which are already very mature. In fact, this is mature. , the common technical characteristics, people just need to use it.

在众多专利文献中具有代表性的 CN1231213A文献将污水处理专业工业微波炉的谐振腔外设计一冷却外套，通以冷却水冷却谐振腔。这一设计方案在除污水以外的其他流体处理中可能是适用的，但在微波污水处理中却没有必要，因为在微波场中污水得以净化是污水中的极性分子在高速交变的微波电磁场中的的激烈取向运动，将微波能转换为污水中污染物分子的内能，使其能级升高，处于极不稳定状态而积极参与各种物理、化学反应而使污水得以净化，不是靠加热污水而取得的，实际情况证实，大量污水（如- 时处理量为 10(k³)通过 20kw微波场时其温升微乎其微，不存在谐振腔需要冷却的问题。 The CN1231213A document, which is representative in many patent documents, designs a cooling jacket outside the cavity of the sewage treatment professional industrial microwave oven, and cools the cavity by cooling water. This design may be suitable for fluid treatment other than sewage, but it is not necessary in microwave wastewater treatment because the purification of sewage in the microwave field is a microwave electromagnetic field in which high-frequency alternating polar molecules in the sewage are exchanged at high speed. In the intense orientation movement, the microwave energy is converted into the internal energy of the pollutant molecules in the sewage, so that its energy level is increased, and it is in an extremely unstable state and actively participates in various physical and chemical reactions to purify the sewage, instead of relying on Obtained by heating the sewage, the actual situation confirmed that a large amount of sewage (such as - when the treatment volume of 10 (k ³ ) through the 20kw microwave field, its temperature rise is minimal, there is no problem that the cavity needs to be cooled.

又如 CN1231213A文献中用易弯曲的波纹管绕制而成单螺旋状微波污水处理器芯，用夹板捆扎、绳索吊挂的方式解决其固定问题。在污水处理工程中，大流量、高负荷的污水在此结构的处理芯流过时，必定会使其失稳、脱落，且波紋管本身壁薄、内壁粗糙的特性严重影响污水处理过程的安全性。 For example, in the CN1231213A document, a single spiral microwave sewage treatment processor core is wound by a flexible bellows, and the fixing problem is solved by means of plywood bundling and rope hanging. In the sewage treatment project, the large-flow, high-load sewage will surely destabilize and fall off when the treatment core of the structure flows, and the corrugated pipe itself has a thin wall and a rough inner wall, which seriously affects the safety of the sewage treatment process. .

又如 CN101143737A文献推出了一种垂直放置的多层螺旋状芯，其污水进、出水口都处于该多层螺旋状芯的下部，见该文献的附图 2，污水在微波场内通过时，由于在这一过程中会发生各种化学反应，一定会产生气体，如果微波污水处理器芯是上述垂直放置的多层螺旋状芯，气体比液体轻，气体绝对会处于多层螺旋状芯管道的最高处，而不会随污水流上下自由流动，只会形成管道中的气堵而堵塞污永流的流动，当气堵段的气体不断被压缩，管道还有爆裂的危险。 Another example is CN101143737A, which discloses a vertically placed multi-layer spiral core whose sewage inlet and outlet are located at the lower part of the multi-layer spiral core. See Figure 2 of the document, when the sewage passes through the microwave field. Since various chemical reactions will occur in this process, gas will be generated. If the microwave sewage treatment processor core is the above-mentioned vertically placed multi-layer spiral core, the gas is lighter than the liquid, and the gas will definitely be in the multi-layer spiral core tube. The highest point, and will not flow freely with the sewage flow, will only form a gas block in the pipe and block the flow of the flow of the flow. When the gas in the gas block is continuously compressed, the pipe is also in danger of bursting.

又如 CN101143737A的发明内容中所说的 "本发明所要解决的技术问题在于提出一种在污水处理中提高微波穿透能力的微波谐振腔" ，实际上，无论设计何种微波谐振腔，是不能提高微波穿透能力的，因为对一种固定的介质（如某一种污水)，微波的穿透能力是一定值，是不会改变的，因此设计一种较佳的微波谐振腔的指导思想应该是朝着增加单位容积内微波场强度、提高微波利用率的方向下功夫。 Further, as stated in the invention of CN101143737A, "the technical problem to be solved by the present invention is to propose a microwave cavity capable of improving microwave penetration in sewage treatment". Actually, no matter what kind of microwave cavity is designed, it cannot be Improve the microwave penetration ability, because for a fixed medium (such as a kind of sewage), the penetration ability of the microwave is a certain value, it will not change, so the design of a better microwave resonant cavity guiding ideology It should be done in the direction of increasing the intensity of the microwave field in the unit volume and increasing the utilization of microwaves.

又如 CN201033739Y文献所述，采用许多小功率磁控管，来实现输入功率的可调；作为污水处理，一般来说，其处理能力小至日处理几百吨大至日处理一百万吨，如果都采用小功率磁控管来调节其输出功率，在实验室是可能的，对较大的污水处理项目就不可取了。据市场调査，我国的磁控管生产状况是：频率 915MHz的磁控管只有 20kw的，往上的大功率管还正处于研制阶段，往下的小功率管还未形成系列，国外有大到 lOOkw的，但价格十分昂贵，据咨询，德国造的 lOOkw磁控管价格为 10万欧元，是很难接受的。频率 2450MHz的磁控管最大功率是 10kw，往下的小功率管已成系列产品，如家用微波炉选用的是 lkw的。用在污水处理领域的波源使用的磁控管一般选用 915ffilz 、 20kw的和 2450MHz 、 10kw的，至于功率连续可调的控制***也早已实现。因此用 lkw或几 kw的微波波源对污水处理来说太小，是不适用的。因此，本发明的一种微波污水处理器就是基于 915MHz- 20kw和 2450MHz- 10kw两种波源而设计的。 As described in CN201033739Y, many low-power magnetrons are used to achieve adjustable input power. As a sewage treatment, in general, its processing capacity is as small as several hundred tons per day and one million tons per day. If you pick The use of low-power magnetrons to regulate their output power is possible in the laboratory and is not desirable for larger wastewater treatment projects. According to market research, China's magnetron production status is: The frequency of 915MHz magnetron is only 20kw, the high-power tube is still in the development stage, the small power tube has not formed a series, the foreign has a large To lOOkw, but the price is very expensive, according to the consultation, the price of lOOkw magnetron made in Germany is 100,000 euros, which is very difficult to accept. The maximum power of the magnetron with a frequency of 2450MHz is 10kw, and the small power tube down has become a series of products, such as the lww of the household microwave oven. The magnetrons used in the wave source of the sewage treatment field generally use 915ffilz, 20kw and 2450MHz, 10kw, and the control system with continuously adjustable power has also been realized. Therefore, using a microwave wave source of lkw or several kw is too small for sewage treatment and is not applicable. Therefore, a microwave sewage treatment device of the present invention is designed based on two wave sources of 915 MHz - 20 kw and 2450 MHz - 10 kw.

从上述的背景技术文献可见，目前尽管出现了不少处理器，但无论是设计的理论基础还是推出的具体设计方案都不尽如人意。 It can be seen from the above background art literature that although there are many processors present, the theoretical basis of the design or the specific design schemes introduced are not satisfactory.

具体实施方式 detailed description

见图 1、 2、 3，本发明包括：一个微波谐振腔体 2，于腔体 2内设置有一个处理芯 1，腔体 2—侧设置有与微波源连接的波导管 3。该微波谐振腔体 2的一侧开一与标准波导管相对应的矩形口，波导管 3与该矩形口对接焊接，且波导管 3与腔体 2互成 90度角。 Referring to Figures 1, 2, and 3, the present invention comprises: a microwave resonant cavity 2 in which a processing core 1 is disposed in the cavity 2, and a cavity 3 connected to the microwave source is disposed on the side of the cavity. One side of the microwave cavity 2 is opened with a rectangular port corresponding to the standard waveguide, and the waveguide 3 is butt welded to the rectangular port, and the waveguide 3 and the cavity 2 are at an angle of 90 degrees with each other.

腔体 2的上、下面分别开一圆孔作为出水口 5和进水口 6，其位置与处理芯 2的出水管 15、进水管 11、相对应，尺寸大小比处理芯 2的出水管 15、进水管 11外径大 5~10mm。污水由腔体 2的进水口 6进入处理芯 1，并由出水口 5流出。 A circular hole is formed in the upper and lower sides of the cavity 2 as the water outlet 5 and the water inlet 6, and the position thereof is corresponding to the outlet pipe 15 and the inlet pipe 11 of the processing core 2, and the size is larger than the outlet pipe 15 of the processing core 2. The inlet pipe 11 has an outer diameter of 5 to 10 mm. The sewage enters the treatment core 1 from the water inlet 6 of the chamber 2 and flows out of the water outlet 5.

所述的腔体 2为截面为正方形的长方体，采用厚 4mm的 SU304不锈钢 2B板材焊接而成。腔体 2之所以设计成水平截面为正方形的长方体，是因为：金属反射微波，与腔体 2垂直设置的波导管 3将微波垂直导入长方体腔体 2中，可使置于腔体中央的处理芯处于最佳的微波暴露状态，水平截面为正方形是为了使腔体 2和置于腔体 2内的处理芯 1在空间上获得最佳匹配，避免因腔体 2的空间浪费造成单位容积微波场强降低。腔体 2内壁采用性价比较高的不锈钢材质。对于腔体 2的外壳以及主体支架的材质无太多要求，一般采用具有一定强度、不透波、容易加工的材料即可，例如采用价格较为便宜的普通钢材。 The cavity 2 is a rectangular parallelepiped having a square cross section and is welded by a SU304 stainless steel 2B plate having a thickness of 4 mm. The cavity 2 is designed as a rectangular parallelepiped in a horizontal section because: the metal reflects the microwave, and the waveguide 3 disposed perpendicularly to the cavity 2 vertically introduces the microwave into the rectangular cavity 2, so that the cavity can be disposed in the center of the cavity. The core is in an optimal microwave exposure state, and the horizontal cross section is square for the treatment of the cavity 2 and the cavity 2 The core 1 is optimally matched in space to avoid a reduction in the microwave volume per unit volume due to space waste of the cavity 2. The inner wall of the cavity 2 is made of stainless steel with high cost performance. There is not much requirement for the outer casing of the cavity 2 and the material of the main body bracket, and generally, a material having a certain strength, imperviousness, and easy processing can be used, for example, a common steel which is relatively inexpensive.

所述微波谐振腔体 2内部尺寸与所使用的微波波长及处理芯 1的几何尺寸相关。在考虑避免产生驻波的情况下，本发明对不同频率的微波，其腔体 2内部几何尺寸设置如下： The internal dimensions of the microwave cavity 2 are related to the wavelength of the microwave used and the geometry of the processing core 1. In the case of avoiding the generation of standing waves, the present invention sets the internal geometry of the cavity 2 for microwaves of different frequencies as follows:

使用 915MHz波源的谐振腔体内部几何尺寸为 1603 X 1603 X 1093mm。 The internal geometry of the resonator using a 915MHz source is 1603 X 1603 X 1093mm.

使用 2450MHz波源的谐振腔体内部几何尺寸为 1300 X 1300 X 928mm。 The internal cavity of the resonator using a 2450MHz source is 1300 X 1300 X 928mm.

见图 2、 4，处理芯 2是由多层、层内多个同轴圆环体管道串联连接而成。本发明处理芯 2根据不同频率的波源，采用了不同的设计： As shown in Fig. 2 and 4, the processing core 2 is formed by connecting a plurality of coaxial coaxial ring pipes in a plurality of layers in series. The processing core 2 of the present invention adopts different designs according to wave sources of different frequencies:

使用 2450MHz波源时，处理芯为 5层、每层有 4个同轴圆环体管道，见实施例一。使用 915MHz波源时，处理芯为 2层、每层有一个圆环体管道，见实施例二。所述的处理芯 1采用厚 8mm聚丙烯板材和管材焊接而成，处理芯 2是由多层、层内多个同轴圆环体管道串联连接而成。圆环体截面的内尺寸与使用的微波对污水的穿透深度 D_E有关，穿透深度 D_E可由下式求得： When using a 2450MHz wave source, the processing core is 5 layers, and each layer has 4 coaxial torus pipes, as shown in the first embodiment. When using a 915MHz wave source, the processing core is 2 layers, and each layer has a torus tube, see Example 2. The processing core 1 is formed by welding a thick 8 mm polypropylene sheet and a pipe, and the processing core 2 is formed by connecting a plurality of layers and a plurality of coaxial toroidal pipes in a layer in series. The inner dimension of the torus section is related to the penetration depth D _{E of the} used microwave to the sewage. The penetration depth D _E can be obtained by the following formula:

2n^s_r - tgS 2n^s _r - tgS

式中， λ。为自由空间的微波波长， ^为介电常数， tg S为介质损耗。 Where λ. For the microwave wavelength of free space, ^ is the dielectric constant, and tg S is the dielectric loss.

使用 2450MHz波源的处理芯 2的圆环体截面的内尺寸为 80 X 80mm。 The inner diameter of the torus of the treatment core 2 using the 2450 MHz wave source is 80 X 80 mm.

使用 915MHz波源的处理芯 2的圆环体截面的内尺寸为 300 X 300mm。 The inner diameter of the torus of the treatment core 2 using the 915 MHz wave source is 300 X 300 mm.

见图 2、 3，这是本发明实施例一，本实施例是适用于频率为 2450MHz的微波波源。本实施例中处理芯 1采用了由五层、层内由四个同轴圆环体管道串联连接而成。具体包括：纵向分布的五层圆环体多级管道体 12以及将多级管道体 12逐层连通的纵向连接管 14；其中每层管道体 12包含四个同轴圆环体管道 131、 132、 133、 134。每个圆环体管道 131、 132、 133、 134内设置有隔板 17，并且两相邻圆环体管道之间通过横向连接管 16连通。 Referring to Figures 2 and 3, this is the first embodiment of the present invention. This embodiment is applicable to a microwave wave source having a frequency of 2450 MHz. In the present embodiment, the processing core 1 is formed by connecting five layers in a layer and four coaxial toroidal tubes in series. Specifically, the utility model comprises: a longitudinally distributed five-layer annular body multi-stage pipe body 12 and a longitudinal connecting pipe 14 connecting the multi-stage pipe body 12 layer by layer; wherein each pipe body 12 comprises four coaxial toroidal pipes 131, 132 , 133, 134. A partition plate 17 is disposed in each of the toroidal tubes 131, 132, 133, and 134, and two adjacent toroidal tubes are communicated through the transverse connecting tubes 16.

本实施例工作原理为：污水在处理芯 1管道内部旋流，汽、液流动同方向。每层、每个圆环体管道腔的高度和宽度，层与层之间的间距均为 2450MHz微波对污水的穿透深度的 2倍，约为 2 X 40mm，这样不管微波从哪个方向作用于污水，都使反应腔体 2里的微波得到最有效的利用。污水在圆环体管道内旋流，增大了污水停留时间，使其能均匀、充分的吸收微波能。 The working principle of this embodiment is as follows: The sewage is swirled inside the processing core 1 pipe, and the steam and liquid flow in the same direction. The height and width of each layer and each toroidal pipe cavity, the spacing between layers is 2450MHz. Two times the degree, about 2 X 40mm, so that the microwave in the reaction chamber 2 can be most effectively utilized regardless of the direction in which the microwave acts on the sewage. The sewage swirls in the toroidal pipe, which increases the residence time of the sewage, so that it can absorb microwave energy evenly and fully.

参见图 3，被处理的污水从处理芯 1的迸水管 11进入处理芯 1的第一层圆环体多级管道体 12内的最外一个圆环体管道 131内，并由隔板 17的左侧做顺时针方向的圆形环流。在腔内隔板 2右侧，污水从环与环之间的横向连接管 16进入第一层中第二级圆环体管道 123，在该腔内做逆时针方向的圆形环流；在该腔内隔板 2的左侧，污水从环与环之间的横向连接管 16进入第三级圆环管道 133，在该第三级圆环体管道 133腔内做顺时针方向的圆形环流。在该腔内隔板 2的右侧，污水从环与环之间的横向连接管 16进入第四级圆环体管道 134，在该管道腔内做逆时针方向的圆形环流；最后，在该腔内隔板 2的左侧，污水从层与层之间的纵向连接管 14迸入第二层圆环体多级管道体 12, 相对第一层的流向，污水在处理芯 1的第二层将反向运动，直至进入第三层圆环体多级管道体，如此流动，直至污水从处理芯 1排出为止。 Referring to Fig. 3, the treated sewage enters the outermost toroidal tube 131 in the first layer of the toroidal multi-stage pipe body 12 of the treatment core 1 from the water tube 11 of the treatment core 1, and is partitioned by the partition 17 A circular circulation in the clockwise direction on the left side. On the right side of the intracavity partition 2, the sewage enters the second-stage annular body pipe 123 in the first layer from the transverse connecting pipe 16 between the ring and the ring, and a circular circulation in the counterclockwise direction is performed in the cavity; On the left side of the inner partition 2, the sewage enters the third-stage annular duct 133 from the transverse connecting pipe 16 between the ring and the ring, and makes a circular circulation in the clockwise direction in the cavity of the third-stage annular body pipe 133. . On the right side of the inner partition 2 of the chamber, the sewage enters the fourth-stage toroidal pipe 134 from the transverse connecting pipe 16 between the ring and the ring, and a circular circulation in the counterclockwise direction is made in the pipe cavity; On the left side of the inner partition 2, the sewage is plunged from the longitudinal connecting pipe 14 between the layers into the second layer of the toroidal multi-stage pipe body 12, with respect to the flow direction of the first layer, and the sewage is treated at the first of the processing core 1. The second layer will move in the opposite direction until it enters the third layer of the torus multi-stage pipe body, so that it flows until the sewage is discharged from the treatment core 1.

为了确保层与层之间圆环体多级管道体 12之间的稳固，在圆环体多级管道体 12之间设置有支撑柱。该支撑柱同样采用聚丙烯制作。另外，为了便于将整个处理芯 1与腔体 2定位，在处理芯 1上下端面均设置有用于与谐振腔固定、定位的聚丙烯支撑柱。 In order to ensure the stability between the torus multi-stage pipe body 12 between the layers, a support column is disposed between the torus multi-stage pipe bodies 12. The support column is also made of polypropylene. In addition, in order to facilitate positioning of the entire processing core 1 and the cavity 2, a polypropylene support column for fixing and positioning with the resonant cavity is disposed on the upper and lower end faces of the processing core 1.

见图 4，这是本发明的第二实施例。本实施例是与频率为 915MHz的微波波源像配套。其处理芯 1为 2层、每层有一个圆环体管道。具体包括：纵向两层分布的圆环体单级管道 18以及将单级管道 18逐层连通的纵向连接管 14;每层单级管道 18内部设置隔板 17，污水在单级管道 18内单向旋流，气、液同向流动。每层圆环体管道的高度和宽度，层与层之间的间距均为 915MHz微波对污水的穿透深度的 2倍，约为 2 x 150mm,这样不管微波从哪个方向作用于污水，都使反应腔里的微波得到最有效的利用。污水的具体流向可参照上述实施例一所述，这里不在一一赘述。 Referring to Figure 4, this is a second embodiment of the present invention. This embodiment is matched with a microwave wave source image having a frequency of 915 MHz. The processing core 1 has 2 layers, and each layer has a toroidal tube. Specifically, the utility model comprises: a longitudinally two-layer distributed circular body single-stage pipe 18 and a longitudinal connecting pipe 14 which connects the single-stage pipe 18 layer by layer; a partition 17 is arranged inside each single-stage pipe 18, and the sewage is single in the single-stage pipe 18 To the swirl, the gas and liquid flow in the same direction. The height and width of each layer of toroidal pipe, the spacing between the layers is twice the penetration depth of the 915MHz microwave to the sewage, about 2 x 150mm, so that no matter which direction the microwave acts on the sewage, The microwave in the reaction chamber is most effectively utilized. The specific flow direction of the sewage can be referred to the above-mentioned first embodiment, and will not be described herein.

为确保管道 18之间的稳固连接，以及确保整个处理芯 1的结构稳固，在处理芯 1 上、下端面以及管道 18之间设置有支撑柱。该支撑柱釆用聚丙烯制作。与实施例一一样，为了便于将整个处理芯 1与腔体 2定位，在处理芯 1上下面上均连有用于与谐振腔定位的聚丙烯支撑柱。 In order to ensure a firm connection between the pipes 18 and to ensure the structural stability of the entire process core 1, a support column is provided between the upper and lower end faces of the process core 1 and the pipe 18. The support column is made of polypropylene. As in the first embodiment, in order to facilitate positioning of the entire processing core 1 and the cavity 2, a polypropylene support column for positioning with the cavity is attached to the upper surface of the processing core 1.

结合上述两个实施例，处理芯 1的上、下两端分别设置有与腔体 2出水口 5和进水口 6对应的出水管 15和进水管 11。采用这种结构是考虑到污水处理过程中可能会产生一定量的气体，下端进水、上端出水的构造使气液同向流动，利于气体排放。腔体上下出、进水口 5、 6处均设有密封、屏蔽装置 4，该密封、屏蔽装置 4既保证了处理芯 1内的污水与腔体 2之间的互不相通，又可以保证腔体 2中微波场的规整性，很好地屏蔽了微波的外泄，其加工和更换极其容易。 In combination with the above two embodiments, the upper and lower ends of the processing core 1 are respectively provided with an outlet pipe 15 and an inlet pipe 11 corresponding to the water outlet 5 and the water inlet 6 of the cavity 2. The adoption of this structure takes into consideration that a certain amount of gas may be generated during the sewage treatment process, and the structure of the lower end water inlet and the upper end water outlet allows the gas and liquid to flow in the same direction, which is favorable for gas discharge. The sealing body and the shielding device 4 are arranged at the upper and lower outlets of the cavity and the water inlets 5 and 6. The sealing and shielding device 4 not only ensure the mutual communication between the sewage in the processing core 1 and the cavity 2, but also ensure the cavity. The regularity of the microwave field in the body 2 shields the leakage of the microwave well, and it is extremely easy to process and replace.

另外，为把由污水从处理芯 1携带出来的极少量的微波完全消耗完，在出水口 5、进水口 6处设置金属水负载。上述防止微波泄漏的水负载是在污水进、出水口外设置用钢材制作的其长度超过微波穿透深度 2~3倍长度的弯管。 Further, in order to completely consume the extremely small amount of microwaves carried by the sewage from the treatment core 1, a metal water load is placed at the water outlet 5 and the water inlet 6. The above-mentioned water load for preventing microwave leakage is an elbow made of steel material outside the inlet and outlet of the sewage and having a length exceeding 2 to 3 times the depth of the microwave penetration.

使用 915MHz的波源时所述的防止微波泄露的水负载的长度为 450mm。 The length of the water load to prevent microwave leakage when using a 915 MHz wave source is 450 mm.

使用 2450MHz的波源时所述的防止微波泄露的水负载的长度为 120mm。 The length of the water load to prevent microwave leakage when using a 2450 MHz wave source is 120 mm.

具体而言，所述的水负载是在腔体 2出水口 5处设置的金属弯管 51和进水口 6处设置的金属弯管 61。 Specifically, the water load is a metal elbow 51 provided at the water outlet 5 of the cavity 2 and a metal elbow 61 provided at the water inlet 6.

见图 5，所述的处理芯 1上下两端的出水管 15与进水管 11处分别有密封、屏蔽装置 4，该密封、屏蔽装置 4包括：带法兰及网孔的内螺纹压盖 41、密封圈 42以及焊接在腔体 2进、出水口处的外螺紋管 43, 其中带法兰的压盖 41与外螺紋管 43螺紋连接，密封圈 42位于进、出水管 11、 15的端面，并且在压盖 41与外螺紋管 43螺紋连接挤压下被压紧，保证了污水不会流进谐振腔体 2。带法兰的压盖 41中心有供污水流出（或流进）的网孔 411，它可有效减小微波的泄露量，保证腔体 2中微波场的规整性。即使有少量微波泄露，也会通过在进、出口水管 11、 15组件上设置的水负载使少量随污水泄出的微波被水彻底吸收。 As shown in FIG. 5, the outlet pipe 15 and the inlet pipe 11 of the upper and lower ends of the processing core 1 respectively have a sealing and shielding device 4, and the sealing and shielding device 4 comprises: an internal thread gland 41 with a flange and a mesh hole, a sealing ring 42 and an externally threaded pipe 43 welded to the inlet and outlet of the cavity 2, wherein the flanged gland 41 is screwed to the externally threaded pipe 43, and the sealing ring 42 is located at the end faces of the inlet and outlet pipes 11, 15. Moreover, the gland 41 is pressed against the externally threaded tube 43 by screwing, thereby ensuring that the sewage does not flow into the resonant cavity 2. The flanged gland 41 has a mesh 411 for discharging (or flowing in) the sewage, which can effectively reduce the leakage of the microwave and ensure the regularity of the microwave field in the cavity 2. Even with a small amount of microwave leakage, a small amount of microwaves discharged from the sewage are completely absorbed by the water through the water load placed on the inlet and outlet water pipes 11, 15.

使用本发明时，污水通过位于腔体 2下方的进水口 6进入处理芯 1的管道内，不断向上单向旋流。污水在流动过程中，在波导管垂直导入的微波磁场作用下，积极发生各种物化反应，产生的各种气态、固态、液态物质随污水经出水口 5流出，进入后续处理设备。 In the case of the present invention, the sewage enters the pipe of the treatment core 1 through the water inlet 6 located below the cavity 2, and is continuously unidirectionally swirled upward. During the flow of sewage, under the action of the microwave magnetic field vertically introduced by the waveguide, various physical and chemical reactions occur actively, and various gaseous, solid and liquid substances generated flow out along with the sewage through the water outlet 5 and enter the subsequent processing equipment.

本发明的优点是：单位容积微波场强大、加工简单、固定牢靠、气体排放顺畅、成本低廉。可广泛应用于各种生产、生活污水的处理。 The invention has the advantages of: strong microwave field per unit volume, simple processing, firm and firm, smooth gas discharge and low cost. Can be widely used in the processing of various production and domestic sewage.
