降低吸烟危害的过滤嘴技术领域：本发明涉及巻烟过滤嘴。 Reducing the hazards of smoking filter Technical Field: The present invention relates to a filter cigarette Volume. 背景技术：吸烟者在吸烟时，巻烟中含有的有害物质以及巻烟燃烧时产生的有害物质被吸入体内，对人体产生严重危害。 BACKGROUND: When smokers smoke, harmful substances produced during combustion of harmful substances and Volume Volume cigarette smoke contained inhaled, cause serious harm to human body. 过滤嘴是降低这种危害的最主要和最关键的手段。 This filter is to reduce the harm of the most important and most critical means. 普通过滤嘴有醋酸纤维过滤嘴和聚丙烯纤维过滤嘴。 Plain filter with a cellulose acetate filter and a polypropylene fiber filter. 由于这些普通过滤嘴是由单一过滤材料形成过滤体，其过滤性能受到过滤材料本身特性的限制，因而其降低吸烟危害的功能仍有所欠缺。 Since these plain filters the filter body is formed from a single filter material, the filtration performance is limited by the characteristics of the filter material itself, which thus functions to reduce the dangers of smoking is still lacking. 如醋酸纤维带有部分负电荷，极性较弱， 除了任何纤维都有的机械阻挡和沉积截留作用外，只对带有正电荷的粒子、离子和极性较强的分子有吸附作用，而对带有负电荷的粒子、离子和弱极性分子作用甚微。 The cellulose acetate with a partial negative charge, the less polar, in addition to any fiber has mechanical and barrier deposition interception, only adsorption of particles, ions and polar molecules with a positive charge, and particle having a negative charge, ions and weakly polar molecules had little effect. 而聚丙烯纤维分子结构为非极性结构，虽然对焦油截留作用明显， 但是却更加没有对烟气中极性分子和带电粒子的吸附能力。 And non-polar molecular structure polypropylene fiber structure, although significant tar Interception, but no more smoke adsorption capacity for polar molecules and charged particles. 改进的过滤嘴，即所谓特殊滤嘴有很多。 Improved filters, there are many so-called special filters. 如含有活性炭的过滤嘴，含有纳米材料、自由基清除剂、催化剂，能与烟气中有害物质起化学反应的添加物等的过滤嘴，以及添加香味物质或起保健作用物质的过滤嘴。 The filter containing activated carbon, nano-materials containing, radical scavengers, catalysts, harmful substances in flue gases can be chemically reacting additives such as a filter, and add aroma or from the health effects of the filter material. 这些特殊滤嘴各有其独到的优特点，在降低吸烟危害方面取得了效果，而且有些已经应用于实际生产。 These special filters have their own unique advantages and characteristics, achieved results in reducing the dangers of smoking, and some have been used in actual production. 然而，这些过滤嘴却依然存在诸多待完善的地方。 However, these filters still there are many to be the perfect place. 因为它们有的结构复杂，不利于实际应用和利用现有的生产条件（如设备）；有的原料成份繁多，甚至用到来源稀少的需要特制的物质，因而不利于广泛应用。 Because of the complex structure of some of them, it is not conducive to the practical application and use of existing production conditions (such as equipment); some raw ingredients many, even the need to use scarce sources of special material, which is not conducive to a wide range of applications. 中国专利ZL01806799. 9的"香烟过滤嘴"提供了用甲壳素及其衍生物纤维丝束制成丝束滤棒的过滤嘴。 China Patent ZL01806799. 9 is "cigarette filter" provides a filter plug is made from tow fiber tows with chitin and its derivatives. 这种过滤嘴利用甲壳素及其衍生物纤维丝束滤材上含有的阳离子活性基团对烟气中极性分子进行高效率的截滤，可以大量吸附烟气中带负电荷的颗粒物质，从而解决了带有负电荷的醋酸纤维丝束滤材不能有效吸附烟气中带负电荷的颗粒物质的问题。 Such a filter using a cationic reactive group contained in the fibrous tow filter chitin and its derivatives on polar molecules in the flue gas efficiently cut filter, can adsorb a large amount of particulate matter in the flue gas negatively charged, so that acetate tow solve the problem of filtering medium having a negative charge can not effectively adsorb the particulate matter in the flue gas are negatively charged. 然而单独使用这种纤维作为过滤嘴的滤材，显然对烟气中带正电荷的颗粒物质作用甚微。 However, such fibers used alone as the filter medium, the particulate material apparently acting positively charged smoke minimal. 即使与醋酸纤维混用 Even if mixed with cellulose acetate
制成复合香烟过滤嘴，由于醋酸纤维含活性基团少，极性较弱，对带有正电荷的颗粒物吸附量有限，对弱极性分子的作用也弱，所以仍然不能非常有效在降低吸入人体的烟气中有害物质的数量。 A composite cigarette filters, since cellulose acetate with less reactive groups, the less polar, limited to particles with a positive charge adsorption, the role of the weak polar molecules is weak, it is still not very efficient in reducing respirable the number of harmful substances in the flue gas. 在人类越来越关注健康珍惜生命的时代，在《烟草框架公约》得到越来越多的国家政府签署的局势下，在巻烟产品市场趋于国际化，竟争越来越激烈的环境中，如何有效地降低巻烟中的有害物质以及巻烟燃烧时产生的有害物质进入人体的数量，而且采取的措施和方法要简便易行，有利于充分利用现有生产条件和适宜广泛应用，就成为了巻烟行业无法回避的甚至关系到行业生存危险的重大课题。 In an era increasingly concerned about human health cherish life, in more and more situations governments signed "Framework Convention on Tobacco", the tobacco products market in Volume more internationally oriented, increasingly fierce competitive environment how to effectively reduce the Volume smoke harmful substances and hazardous materials generated during combustion Volume smoke into the number of the human body, but also to take measures and methods to be easy, help make full use of existing production conditions and suitable for a wide range of applications, it is Volume tobacco industry has become unavoidable even to survive dangerous industry a major issue. 发明内容：本发明的目的是提供一种能有效降低进入人体的烟气中有害物质数量，且方便于生产应用的降低吸烟危害的过滤嘴。 SUMMARY OF THE INVENTION: The purpose of the present invention to provide an amount effective to reduce the harmful substances in the flue gas into the body, and conveniently to reduce the dangers of smoking filter plug applications. 为了实现发明目的，本发明在包含过滤体的过滤嘴中，使过滤体的过滤材料含有阳离子交换纤维和阴离子交换纤维。 To achieve the object of the invention, the present invention is a filter comprising a filter body, the filter material of the filter body containing a cation exchange fibers and anion exchange fibers. 本发明发现，吸烟者吸入的烟气中的有害物质中，绝大多数都是极性分子物质和带有电荷的离子、粒子。 The present inventors have found that, in the smoke inhaled by a smoker harmful substances, most of them are polar molecular species with charged ions and particles. 粒子所带的电荷是因为它们随着气流运动（吸动）时与烟丝、包覆层和过滤材料发生摩擦，以及在约束状态下（在相对密闭的烟支内）互相摩擦而产生的表面静电。 Is the electric charge of the particles due to friction, and in a constrained state (in a relatively closed cigarettes) mutual friction generated by their occurrence and tobacco, and a cladding layer with the filter material when air movement (pull-in) static surface . 极性分子有正电端和负电端，带电荷的离子和粒子有带正电荷的，也有带负电荷的。 Polar molecule is positively charged and a negative electrical terminals, charged ions and positively charged particles have, but also negatively charged. 无论阳离子交换纤维，还是阴离子交换纤维，都具有很多的电性很强的荷电基团。 Whether cation exchange fiber, or anion-exchange fiber, have a lot of highly charged electrical groups. 阳离子交换纤维上的荷电基团荷正电，阴离子交换纤维上的荷电基团荷负电。 Charged cation-exchange groups on the positively charged fiber, anion-exchange charged groups on the negatively charged fibers. 当烟气由于吸烟而运动到与离子交换纤维接触时，带正电荷的离子和粒子立即被阴离子交换纤维上的荷负电的基团牢牢吸住，带负电荷的离子和粒子则立即被阳离子交换纤维上的荷正电基团牢牢吸住。 When the flue gas moving due to smoking in contact with an ion exchange fiber, ion particles are positively charged, and immediately anion exchange negatively charged groups on the fibers firmly suck, negatively charged particles and the ions are cations immediately positively charged groups on the fibers firmly suck exchange. 而极性分子由于结构体两端（极）的电性相异，基本上是遇着哪种离子交换纤维就被哪种离子交换纤维吸住，而且是被强有力地吸住。 Since the structure and polar molecules at both ends (poles) different electrical, which is substantially hear of ion-exchange fibers which ion exchange fiber was sucked, and is strongly sucked. 正是由于离子交换纤维的荷电基团很多，电性又很强，所以即使是弱极性分子和穿透力很强、运动速度很快、不容易被直接截留的微小粒子（当然这种微小粒子也是带有电荷的），也会因为强大的电的吸引力而被吸附到离子交换纤维上。 It is because the ion-exchange group charged many fibers, and electrically strong, even if weak and strong penetration of polar molecules, fast motion, is not easy to directly trapped fine particles (of course, this fine particles are electrically charged), also because of the strong attraction is electrically adsorbed to the ion exchange fibers. 烟草是植物，其生长过程中，烟叶中必然富集土壤中的重金属、砷盐、亚硝酸盐等各种有害物质，这些有害物质在人们吸烟时也含有以各种形态特别是离子形态进入人体。 Tobacco is a plant during its growth, soil heavy metals, arsenic salt, nitrite and other harmful substances in tobacco enriched necessarily, these harmful substances when people smoke also contains a variety of forms in particular form of ions into the body . 离子交换纤维源自于离子交换树脂，离子交换树脂的主要功能是去除水中的各种金属离子、砷及其盐和酸根离子，但离子交换树脂不适宜于对气体中的这些物质的去除，因而离子交换纤维应运而生。 The main function of the ion exchange fibers derived from ion exchange resins, ion exchange resins are various metal ions, arsenic ions and salts and remove the water, but the ion exchange resin is not suitable for the removal of these substances from the gas, and thus ion exchange fiber came into being. 可以说，离子交换纤维，天然地就是用来除去气体中的各种重金属、砷盐、亚硝酸盐和硫化物、碳化物、氯化物、氮化物、氰化物等有害物质的。 It can be said, ion exchange fiber, is naturally used to remove heavy metals in the gas, arsenic salts, nitrites and sulfides, carbides, chlorides, nitrides, cyanide and other harmful substances. 含有离子交换纤维的过滤嘴，能针对性地除去烟气中的这些有害物质，使这些有害物质在进入人体的烟气中大为减少。 Containing an ion exchange fiber filter, it can be targeted to remove these harmful substances in the flue gas, so that significant reduction of these harmful substances into the body of the flue gas. 离子交换纤维也是很细的纤维，具有与醋酸纤维、聚丙烯纤维或甲壳素及其衍生物纤维一样的对烟气中各种有害物质的直接截留、惯性碰撞和扩散沉积等物理过滤作用。 Ion exchange fibers are very fine fibers having a cellulose acetate, polypropylene fibers, or their derivatives chitin fiber as direct interception of harmful substances in the flue gas, inertial impaction and diffusion deposition, physical filtration action. 因此，含有阳离子交换纤维和阴离子交换纤维的过滤嘴，对流经该过滤体的烟气中的有害物质，既有直接截留、惯性碰撞和扩散沉积作用，还有强大的电吸附作用，既能吸附极性强的分子，也能吸附极性弱的分子，既能吸住带正电的离子和粒子，也能吸住带负电的离子和粒子，既能阻截较大的粒子，也能吸附微小的粒子，既能吸附碱性物质，又能吸附酸性物质，所以，比之现有技术中的醋酸纤维、聚丙烯纤维、甲壳素及其衍生物纤维以及甲壳素及其衍生物纤维与醋酸纤维的复合结构，能阻隔更多的烟气中的有害物质，使烟气中有害物质进入人体的数量大大减少，更加有效地降低了吸烟对人体的危害。 Accordingly, fibers having cation exchange and anion exchange fiber filter, the flue gas flows through the filter body of harmful substances, both direct interception, inertial impaction, and diffusional deposition action, there is a strong adsorption power, both electrode adsorbing strong molecules can adsorb weakly polar molecules, both to suck particles and positively charged ions, but also negatively charged ions suck and particles, both blocking larger particles, but also can absorb slight particles, adsorption of both basic substance, acidic substance adsorbed can, therefore, than the prior art cellulose acetate, polypropylene fiber, chitin fiber, and derivatives thereof, and chitin and derivatives thereof and cellulose acetate fibers composite structures, can block more of the harmful substances in the flue gas, the flue gas in the number of harmful substances into the body is greatly reduced, more effectively reduce the harm of smoking on the human body. 离子交换纤维（包括阳、阴两种）是与醋酸纤维或聚丙烯纤维一样的细小长纤维，所以用离子交换纤维来制作过滤嘴，就如同现在用醋酸纤维或聚丙纤维制作过滤嘴一样。 Ion exchange fibers (including male and female, two) is cellulose acetate or polypropylene fibers as fine long fibers, the fibers produced by ion-exchange filter, the filter is now just as cellulose acetate or polypropylene fibers making the same. 在制作离子交换纤维过滤嘴时，可充分利用现有的生产条件和设备，不需要添加新设备，也不需要对现有设备作大的改动，采取与现行工艺基本相同的方法即可。 When the production of ion exchange fiber filter, can take full advantage of existing equipment and production conditions, the need for new equipment, does not require significant modification of existing equipment, to take the current process can be substantially the same manner. 离子交换纤维作为一种应用非常广泛的产品，其生产已经完全实现了工业化，国内外都有大规模的生产。 Ion exchange is widely used as a fiber product, its production has been fully realized industrialization, we have large-scale production at home and abroad. 产品种类繁多，而且可以利用不同的原料纤维采用不同的生产工艺，得到物理和化学性能各具特色的产品。 Wide range of products, and may utilize different materials with different fiber manufacturing processes, to give distinctive physical and chemical properties of the product. 这为过滤嘴选材 This selection is a filter
提供很大的便利，为离子交换纤维在巻烟过滤嘴上的应用提供了丰富的原料来源和供应保障。 Provide great convenience for the ion exchange fiber applications mouth filter in Volume smoke provides a rich source of raw materials and supply security. 可用于本发明的离子交换纤维有很多，如带有胺基活性基团的聚苯乙烯/聚丙烯共混弱碱性阴离子交换纤维；以聚乙烯醇基纤维经过半碳化_>酸化醚化—胺化—转型处理得到的阴离子交换纤维；含胺基的丙烯腈-甲基丙烯酸甲酯-衣康脂的离子交换纤维；由聚四氟乙烯通过核辐射接枝— 接枝纤维磺化后所得的强酸性阳离子交换纤维；采用腈纶纤维和水合肼先进行预交联然后再在酸性条件下或碱性条件下水解而制备的离子交换纤维；以及在腈纶纺丝原液中加入聚乙撑亚胺制得的强碱阴离子交换纤维，再通过睛基的碱水解制得的两性离子交换纤维；还有以聚苯乙烯和少量聚丙烯共混作海组份和以聚丙烯为岛组份经过熔融纺丝制得的海岛型复合纤维，通过进一步化学处理， 在聚苯乙烯上引入交联基和离子交换、螯合基团，得到的阴，阳离子交换和螯合纤维； Ion-exchange fibers used in the present invention, there are many, such as an amine with a reactive group of a polystyrene / polypropylene blends weakly basic anion exchange fibers; polyvinyl alcohol-based semi-carbonized fiber was _> acidified etherified - amination - anion exchange fibers obtained by transformation process; amino group-containing acrylonitrile - methyl methacrylate - itaconic butter ion exchange fiber; polytetrafluoroethylene by radiation grafting - grafted fibers obtained after sulfonation strongly acidic cation exchange fibers; acrylic fiber using hydrazine hydrate and then ions to be pre-crosslinking and then hydrolyzed under acidic conditions or basic conditions prepared exchange fibers; and the added polyethylene imine acrylic spinning dope the resulting strongly basic anion exchange fibers, and then through the eye zwitterionic groups resulting alkaline hydrolysis exchange fibers; and a small amount of a blend of polypropylene and polystyrene as the sea component and polypropylene as the islands component melt-spun through silk obtained sea-island type composite fibers, by further chemical treatment, the crosslinking group is introduced polystyrene ion exchange, chelating group, to give the anion and cation exchange and chelate fiber; 通过化学引发（发辐射接技法制备了两种阳离子交换纤维对铀的吸附性能表明，比相应树脂容易、速度快)、辐照引发的方法将苯乙烯和少量二乙烯基苯接枝到聚乙烯醇无纺布、纤维以及聚丙烯无纺布上，再经过进一步的化学转化，得到的强酸型阳离子交换纤维；用高价铈盐引发，电子束预辐照引发甲基丙烯酸，丙烯酸及少量交联剂一一縮二乙二醇双丙烯酸酯在聚乙烯醇无纺布， 或聚丙烯无纺布上的接枝共聚反应，制得的离子交换容量高的弱酸型阳离子交换纤维以及用聚丙烯腈纤维为基体经交联一水解反应，制成的弱酸阳离子交换纤维等等。 By chemical initiation (irradiation then made two techniques cation exchange adsorption properties of the fibers prepared uranium indicate easier than corresponding resins, speed), the method of radiation induced a small amount of styrene and divinylbenzene to a polyethylene grafted alcohol nonwoven fabric, and non-woven polypropylene fibers, and subjected to further chemical conversion, the resulting strongly acidic cation exchange fibers; initiate a ceric salt, electron beam radiation induced pre-methacrylic acid, acrylic acid and a small amount of cross-linking agent eleven diethylene glycol diacrylate copolymerization of a polyvinyl alcohol nonwoven fabric, polypropylene nonwoven fabric, or graft, made of high ion exchange capacity of the weakly acidic cation exchange fibers and polyacrylonitrile fiber is a crosslinked base hydrolysis, made weakly acidic cation exchange fibers and the like. 综上所述，本发明的用含有阳离子交换纤维和阴离子交换纤维的过滤材料制成的过滤嘴不但能有效降低进入人体的烟气中有害物质的数量，而且可以很方便地应用于实际生产，可以在巻烟行业中被广泛地加以应用。 In summary, with the present invention comprises a filter made of a cation exchange fiber and an anion exchange fiber filter material can not only reduce the amount of flue gas into the body of harmful substances, and can be easily applied to actual production and to be It is to be applied widely in Volume cigarette industry. 此外，离子交换纤维还具有吸附速度快的特点，这一点对于及时有效地阻隔烟气中的有害物质进入人体，也是十分重要的。 Further, the ion exchange fibers also have a fast absorption speed characteristics, which is a barrier for the timely and efficient smoke harmful substances into the body, it is also important. 结合离子交换纤维容量大的特点，就可以使得在可能的情况下减少各种过滤材料的用量，縮短过滤嘴的长度，或者使得现在的长嘴香烟变成短嘴香烟。 Strong cation exchange capacity large fiber characteristics, can be reduced so that the amount of each possible filter material, shortening the length of the filter, so that the current or long cigarette cigarettes become shorter. 阳离子交换纤维还具有明显的杀菌消毒功能，可以有效地阻隔巻烟中的各种微生物和病毒进入人体，避免病从口入，同时还能防止或延缓烟支霉变，改善和提高巻烟吸味品质，延长巻烟的贮存期。 Cation-exchange fibers also have significant sterilization function, can effectively block the smoke Volume various microbes and viruses into the body, to avoid the mouth, while preventing or delaying the cigarette mildew, improve and enhance the smokable Volume taste quality, Volume smoke extend the storage period. 吸烟首先损害的是气管和肺，引起咳嗽、多痰、炎症，最终导致气管癌和肺癌。 Smoking is the first damage the airways and lungs, causing coughing, phlegm, inflammation, eventually leading to tracheal cancer and lung cancer. 人们普遍认为这些损害是由于烟气中的有害物质如苯并比（BaP)、亚硝胺、儿茶酚、甲醛等所致。 It is widely believed the damage was due to the smoke harmful substances such as benzo ratio (BaP), nitrosamines, catechol, formaldehyde caused. 然而本发明发现，真正的罪魁祸首却是微粒。 However, the present inventors have found that the real culprit is particulate. 单纯的上述致癌物质在起态时，即使被吸入人体，也容易被呼出，留在人体中的数量是很少的。 Pure carcinogens at the starting state, even if inhaled, can easily be exhaled, the number of remaining in the body is very small. 但是当存在大量微粒时（烟气的状况正是如此），情况就完全不同了。 But when there are a large number of particles (smoke situation is the case), the situation is completely different. 这些微粒吸附了很多上述致癌物质，甚至达到了饱和。 These particles adsorbed many carcinogens above, even up to saturation. 由于微粒的粒径很细，在吸入力的作用下，可以以及快的速度穿过过滤嘴的过滤体的空隙，达到气管和肺叶，然后沾附其上，既不能下行被人体代谢后排泄，也不能被呼出。 Since the size of the particles is very small, the action of suction force and can quickly pass through the filter body of the filter voids reach the trachea and lungs, and buildup thereon, downstream after being neither human metabolism excretion, and It can not be exhaled. 而吸附在微粒上的致癌物质缓慢地释放出来，对气管和肺近距离地、长久地、 延续不断地发生作用，终致病变。 Adsorbed on the particulate carcinogen slow release, of the trachea and lung closely, long, continuation takes place continuously, finally induced lesions. 因此，减少烟气中微粒进入人体，是降低烟气中的有害物质对人体损伤特别是对气管和肺损伤的关键所在。 Therefore, to reduce the smoke particles enter the body, is especially harmful substances in the flue gas is the key to reducing the trachea and lung injury on the human body injury. 本发明使用阳离子交换纤维和阴离子交换纤维作为过滤材料，将烟气中大量微粒截留，使进入人体的微粒大大减少，从而有效地降低了烟气中有害物质特别是致癌物质对气管和肺的损害，为降低烟民气管癌和肺癌的发病率有特别的重要意义和积极效果。 The present invention is a cation exchange fiber and an anion exchange fiber as a filter material, a large number of particles trapped in the flue gas, so that the particles enter the body is greatly reduced, thus effectively reducing the harmful substances in the smoke carcinogens especially damage to the trachea and lungs to reduce smokers tracheal cancer and lung cancer incidence has special importance and positive effects. 本发明考虑到现有技术的成熟程度和民众对现有技术的熟知程度，为了实现现有技术向新技术的过渡，本发明也可使新技术与现有技术相结合，使过滤体的过滤材料除了含有必需的阳离子交换纤维和阴离子交换纤维这两种离子交换纤维外，还可含有醋酸纤维或聚丙烯纤维。 The present invention contemplates the prior art and the public familiarity with maturity of the prior art, the prior art in order to achieve the transition to the new technology, the present invention also allows new technology with existing technology, the filter of the filter body in addition to the necessary material containing cation-exchange fibers and anion exchange fibers both ion exchange fiber, but may also contain acetate or polypropylene fibers. 而且在这种情况下，两种离子交换纤维与醋酸纤维或聚丙烯纤维可采取混合成束的方式来制造过滤体，也可以先将三种纤维各自成束后各截取一段（即单独成段）然后组合而成为三段式的过滤体。 Also in this case, two kinds of ion exchange fibers and acetate fibers or polypropylene fibers may take the form of a mixed bundle of making a filter body, each of the three fibers may be first taken after each period of the bundle (i.e., separate into segments ) are then combined to become a three-stage filter body. 当然也可以采取两段式的结构，即先将阳离子交换纤维与阴离子交换纤维混合成束后截取一段，再与醋酸纤维的丝束段或聚丙烯纤维的丝束段组合而成过滤体。 Of course, the two-stage configuration can be adopted, that is, first cation-exchange fibers and anion exchange fibers are mixed into the interception of a beam, and then the filter body segment in combination with tow or tow segment polypropylene fibers formed of cellulose acetate. 三段组合结构式的过滤嘴的优点是，不需要对三种纤维进行混合，不必在现有技术条件下增加混丝设备，其缺点是增加了拼接工序。 Advantage of the three-stage filter composition formula is not necessary to mix three fibers, filaments without increasing the mixing device in the prior art conditions, which drawbacks are increased splicing step. 三种纤维混合成束的优点是使得整个过滤体均匀一致，整体感强，无需增加丝束段的拼接工序， 但缺占是要增加混丝设备。 Three fibers mixed advantage bundled so that the entire filter body is uniform, the overall sense, without increasing the tow segments splicing step, but the lack of accounting devices is to increase the fiber mix. 两种离子交换纤维结合醋酸纤维，或者结合聚丙烯纤维，在工艺上、成本 Two kinds of ion exchange fiber binding acetate fibers, polypropylene fibers or a combination, in the process, the cost of
上或民众接受度上，都能保留现有技术的优势，却又大大增加了降低烟气中有害物质的效果。 Or on the acceptance of the people, we can retain the advantages of the prior art, but greatly increases the flue gas to reduce harmful substances in effect. 本发明的过滤嘴中，还可使过滤体中含有特殊添加剂。 The filter according to the present invention, the filter body may also contain special additives. 这些特殊添加剂包括活性炭、血红蛋白、纳米材料如纳米Si02、纳米AU)3、纳米im、纳米Se， 自由基清除剂如血红蛋白、过氧化氢酶、多酚化合物或其衍生物，催化剂如V205、 M0203或RH20、保健剂如V。 These special additives include activated carbon, hemoglobin, nano material such as nano Si02 nano AU) 3, nano-IM, nano-Se, radical scavengers such as hemoglobin, catalase, polyphenol compound or its derivative, a catalyst such as V205, M0203 or RH20, health agent such as V. 、芳香剂如薄荷醇、以及能与烟气中有害物质起化学反应的物质如氧化剂高锰酸钾、二氧化锰等。 , Flavoring agents such as menthol, and can chemically react with the harmful substances in the flue gas substances such as potassium permanganate oxidant, manganese dioxide. 虽然这些特殊添加剂在现有的技术中己被应用，但是本发明中的离子交换纤维却有利于它们充分发挥效能。 Although the special additives have been used in the prior art, but in the present invention, there is ion exchange fiber to facilitate their full effectiveness. 这里的关键因素是离子交换纤维快速及时有效在捕捉到了有害物质，并且使那些没被牢牢捕获的有害物质在过滤体中由于强大的电作用而延长了滞留时间，从而使这些特殊添加剂有足够的时间对有害物质发挥作用。 The key factor here is the ion-exchange fiber quickly promptly and effectively in the capture of harmful substances, and those harmful substances have not been firmly trapped in the filter body due to a strong electric effect, to extend the residence time, so that these special additives have enough time to play the role of harmful substances. 另外，离子交换纤维在其它工业领域被作为催化剂载体加以应用，那么，在本发明中，它也成了这些特殊添加剂的优良载体，稳定地固着着这些特殊添加剂，并可比醋酸纤维和聚丙烯纤维增加固着量，从而使它们能更加有效地发挥作用。 Further, ion exchange fiber is to be in other industrial applications as a catalyst support, then, in the present invention, it has become a good carrier for these special additives, stably fixing of these special additives, and ratio of acetate fibers and polypropylene fibers increasing solid amounts, so that they can more effectively function. 本发明对三元复合滤嘴的改进意义更加积极。 The present invention is more positive significance to improve the ternary complex filter. 三元复合滤嘴的三元指的是醋酸纤维、活性炭和离子交换树脂，或醋酸纤维、活性炭和血红蛋白，归纳起来三元就是醋酸纤维、活性炭和其它某种添加成份。 Ternary complex filter refers to ternary cellulose acetate, activated carbon and ion exchange resins, or cellulose acetate, activated carbon and hemoglobin, is summed up in three yuan acetate fibers, activated carbon and some other added ingredients. 由于离子交换纤维比离子交换树脂质轻，活性基团多，比表面积大，吸附速度快，交换容量大，且对气体中有害物质的吸附更具针对性，所以有了离子交换纤维就完全可以取消离子交换树脂这一"元"。 Since the ion exchange resin fiber light weight than the ion exchange active groups, large surface area, absorption speed, high exchange capacity and the adsorption of harmful substances in the gas more focused, so with the ion exchange fibers can be completely the ion exchange resin cancel "element." 在三元结构中，活性炭的效果是明显的，它能吸附离子交换树脂和醋酸纤维不能吸附和反应的有害成份，但是有了离子交换纤维后就不一样了，许多离子交换树脂和醋酸纤维不能吸附和反应的有害物质，离子交换纤维却能有效截留，这样一来，活性炭的优势明显减小，其用量可以大大降低， 甚至不用活性炭。 In the ternary structure, the effect of activated carbon is significant, it can absorb and acetate ion exchange resin adsorption and reaction are not harmful ingredients, but with ion-exchange fiber is not the same, a number of ion exchange resin and cellulose acetate can not adsorption and reaction of the hazardous substances, able to effectively retain ion exchange fiber, this way, the advantages of the activated carbon is significantly reduced, which can significantly reduce the amount of, or even without activated charcoal. 如此，由醋酸纤维、活性炭和离子交换树脂构成的三元复合滤嘴，在本发明里就可由离子交换纤维这一元取而代之。 Thus, a cellulose acetate, activated carbon and ion exchange resin in the ternary complex filter, an ion exchange fibers can be replaced in this element in the present invention. 浸渍血红蛋白的活性炭是要综合利用血红蛋白和活性炭的作用。 Hemoglobin is impregnated activated carbon to effect utilization of hemoglobin and activated carbon. 如上所述，有了离子交换纤维后， 活性炭的重要性就变得很小了。 As described above, with the ion-exchange fibers, the importance of the activated carbon becomes small. 加之离子交换纤维也能很好地浸渍血红蛋白， 所以由醋酸纤维、活性炭和血红蛋白构成的三元复合滤嘴，就变成离子交换纤维和血红蛋白这二元复合了。 Coupled with the ion exchange fibers are well impregnated with hemoglobin, so a cellulose acetate, activated carbon constituting the hemoglobin and ternary composite filters, ion exchange fiber, and it becomes binary complex of this hemoglobin. 然而更令人可喜的，虽然仍为二元复合，但结构上却从分段、空腔等复杂结构变成了单一的均匀的整体，这为实际生产带来了极大的便利。 But even more gratifying, though still binary complex, but the complex structure never segmented structure, cavities, etc. into a single homogeneous whole, which brings great convenience for the actual production. 本发明的另一种方案是过滤嘴也可只用阳离子交换纤维和阴离子交换纤维作为过滤体的过滤材料，而不添加任何其它纤维或特殊添加剂。 Another embodiment of the present invention is a filter may be provided only exchange fiber and an anion exchange fiber as a filter material with a cation filter body, without adding any special additives or other fibers. 阳离子交换纤维与阴离子交换纤维混合使用，可以产生明显的降低吸入的烟气中有害物质的效果，这在前面已经述及。 Cation-exchange fibers and anion exchange fibers used in combination, can produce significant reduction of harmful substances in the flue gas suction effect, which has been mentioned earlier. 当过滤体的过滤材料不含其它降害效果较差的过滤材料时，阳离子交换纤维和阴离子交换纤维的量就占据了滤材的全部，这样， 即使不使用任何特殊添加剂，也能取得比现有技术更好的降害效果。 When the filter material of the filter body is free of other harmful drop less effective the filter material, the amount of cation exchange fiber and an anion exchange fiber filter to occupy all, so that, even without any special additives, can also obtain current ratio better technology has reduced harmful effect. 而且在另一方面，不含任何其它过滤材料和添加物质的过滤体在生产工艺上也更为简便。 And in another aspect, the filter material free of any other added substances and filter body in the production process is also simpler. 在这里，阳离子交换纤维和阴离子交换纤维可以通过混合成束的方式来制成过滤体，也可以先将它们分别单独成束再截取一段（即单独成段）然后拼接组合而制成过滤体。 Here, the anion exchange fibers and cation exchange fibers may be bundled manner by mixing the filter body to be made, they may be individually first and then to the interception of a beam (i.e., separate into segments) is made by splicing the filter body composition. 当阳离子交换纤维和阴离子交换纤维混合使用作为过滤体的全部过滤材料来制备过滤嘴时，阳离子交换纤维和阴离子交换纤维的用量比例可根据它们各自的交换容量、吸附速度和纤维粗细等因素进行确定。 When the cation exchange fiber and an anion exchange fiber blend used to prepare the filter as a whole a filter material of the filter body, the ratio of the amount of cation-exchange fibers and anion exchange fibers may be determined according to their respective exchange capacity, absorption speed, and the fiber thickness and other factors. 当阳离子交换纤维和阴离子交换纤维只作为过滤体的部分过滤材料时，离子交换纤维的总量（即阳离子交换纤维的用量与阴离子的换纤维的用量之和）可根据其它纤维材料的性质与用量、特殊添加剂的性质与用量以及离子交换纤维的有关因素进行确定，可在全部过滤体重量的5%-99%之间。 When the cation-exchange fibers and anion exchange fibers only as a part of the filter material of the filter body, the total amount of ion-exchange fiber (i.e., an amount of cation exchange fibers and the amount of anion exchange fibers and) according to the nature and amount of other fibrous materials , the nature and amount of ion exchange fibers and related factors that will be determined in special additives, may be between 5% -99% of the total weight of the filter body. 在这里，确定阳离子交换纤维与阴离子交换纤维的用量比例时，需要考虑的因素除了它们各自的交换容量、吸附速度和纤维粗细之外，还需综合考虑其它纤维材料的性质和用量，特殊添加剂的性质和用量。 Here, the factors determining the ratio of the amount of the cation-exchange fibers and anion exchange fibers, to be considered in addition to their respective exchange capacity, absorption speed and thickness of the fibers, the need to consider the nature and amount of other fibrous materials, special additives nature and amount. 例如：由阳离子交换纤维、阴离子交换纤维和醋酸纤维制备过滤体，由于醋酸纤维带有一定量的负电荷，所以阴离子交换纤维的用量可适当减少。 For example: cation exchange fiber, anion exchange fiber, and the filter body prepared cellulose acetate, cellulose acetate with a certain amount due to the negative charge, so that the amount of anion-exchange fibers can be reduced appropriately. 在本发明中还有一种方案，S卩:过滤嘴的过滤体的过滤材料中含有两性离子交换纤维。 Another embodiment, S Jie in the present invention: the filter material of the filter body of the filter containing amphoteric ion exchange fiber. 由于两性离子交换纤维是在同一种纤维上同时含有阳离子基团和阴离子基团，因此兼具阳离子交换纤维和阴离子交换纤维的全部特点，既可以可靠吸附烟气中带正电的离子和粒子，也可以可靠吸附烟气中带负电的离子和粒子，同样也能吸附极性分子和微粒，同时也具备纤维共有的对烟气中有害物质的直接截留、惯性碰撞和扩散沉积作用，因此能获得阳离子交换纤维和阴离子交换纤维混合使用的效果，实现有效降低进入人体烟气中有害物质数量的目的。 Since the amphoteric ion exchange fiber containing a cationic group and an anionic group on the same fiber simultaneously, thus all the features of both cation-exchange fibers and anion exchange fibers, may be reliably adsorbed ions and positively charged particles in the flue gas, can be reliably adsorbed ions and negatively charged particles in the flue gas, and also can absorb polar molecules and particles, but also have a common direct interception of harmful substances in the flue gas, inertial impaction and diffusion fiber deposition, it is possible to obtain cation-exchange fibers and anion exchange fibers mixed use effects to achieve effective reduction of harmful substances into the human amount of smoke purposes. 同时， 使用一种纤维作滤材，在实际生产应用上，比使用两种纤维更加方便。 Meanwhile, use of a fiber as a filter material, in practical application, is more convenient than the use of two types of fibers. 当然，考虑到各种因素，两性离子交换纤维也可与醋酸纤维或聚丙烯纤维混用，混用时，同样也可采取混合成束或单独成段然后组合的方式来制作过滤体，进而制成能降低吸烟危害的过滤嘴。 Of course, taking into account various factors, amphoteric ion exchanger may be mixed with acetate fibers or polypropylene fibers, when mixed, can also take the form of a bundle or separately into mixed segments are then combined to produce a filter body, and thus can be made reduce the dangers of smoking filter. 这里，也一样可以使用各种特殊添加剂，使之与两性离子交换纤维一起发挥协同作用。 Here, too, you can use a variety of special additives, so that the amphoteric ion exchange fiber synergy together. 本发明的最后一种方案是只使用两性离子交换纤维作为过滤体的唯一过滤材料，而不添加任何其它过滤材料或特殊添加剂。 The final embodiment of the present invention is used only as the sole amphoteric ion exchange fiber filter material of the filter body, without adding any special additives or other filtering material. 两性离子交换纤维的特性决定了它可以以一代二（二指的是阳离子交换纤维和阴离子交换纤维），独立地发挥出有效降低进入人体的烟气中有害物质数量的功能。 Amphoteric ion exchange properties of the fibers determines that it may be two generations (finger of cation exchange fibers and anion exchange fibers), independently play reduce the amount of harmful substances in the flue gas into the body of the function. 这里，整个过滤体只由唯一的一种过滤材料制成，其生产工艺以及生产条件与现有技术（指现在的使用醋酸纤维或聚丙烯纤维）最为接近，甚至完全相同，勿容置疑，这种方案是最利于实际生产应用的。 Here, the entire filter body is made of only a single filter material, its production process and the production conditions of the prior art (referring now using acetate or polypropylene fibers) closest to, or even identical, do not doubt, it kinds of programs are most conducive to the actual production applications. 附图说明：图1为本发明的过滤嘴结构示意图；图2为本发明的过滤嘴两段式组合结构示意图；图3为本发明的过滤嘴三段式组合结构示意图。 BRIEF DESCRIPTION OF DRAWINGS: Fig 1 a schematic view of the filter of the present invention; two-stage filter
