背景技术 Background technique

气流通常携带颗粒材料。 Often carry particulate material stream. 在很多场合下,需要从气流中除去某些或全部颗粒材料。 In many instances, it is necessary to remove some or all of the particulate material from the gas stream. 例如,进入机动车辆的发动机或发电设备的进气气流,进入燃气轮机的气流,以及进入各种燃烧炉的空气流通常包括夹带的颗粒材料。 For example, the intake air flow into the engine of a motor vehicle or power generation equipment, gas flow entering the gas turbine, as well as various combustion furnaces into the flow of air entrained particulate material comprises generally. 所述颗粒材料如果到达各种相关设备的内部工作区,可能导致重大破坏。 If the particulate material reaching the internal workings of the various related equipment can result in significant damage. 通常需要从发动机,涡轮机,燃烧炉或其他相关设备的上游气流中除去颗粒材料。 Usually required, furnace or other combustion gas stream upstream of the associated equipment removing particulate material from the engine, a turbine.

本发明涉及用在增强效率(例如)HEPA或ULPA基片上的聚合细纤维合成物。 The present invention relates to enhanced efficiency in (e.g.) a polymeric fine fiber HEPA or ULPA composition on the substrate. 所述细纤维合成物具有改良的特性,可将它用于多种应用中,包括形成纤维,微纤维, 纳米纤维,纤维网,纤维垫,渗透结构如膜,敷层或薄膜。 The fine fiber composition having improved properties, it can be used in various applications, including forming fibers, microfibers, nanofibers, fiber web, fiber mat, permeable structure such as a film, coating or film. 本发明的聚合材料是具有物理特征的合成物,其使得具有各种物理形状或形式的聚合材料能够抵抗湿气,热, 空气流,化学物和机械应力或冲击的降解作用。 Polymeric material of the present invention is a composition having physical characteristics, such polymeric materials which have a variety of physical shapes or forms can withstand moisture, heat, air flow, chemicals and mechanical stress or impact of degradation.

在制造细纤维过滤介质中,业已使用了多种材料,包括玻璃纤维,金属,陶瓷, 和一系列聚合组合物。 In the manufacture of fine fiber filter media, a variety of materials have been used, including fiberglass, metal, ceramics, and a range of polymeric compositions. 业已将多种纤维成型方法或技术用于生产小直径微米和纳米纤维。 The plurality of fibers have been molding method or technology for the production of micro- and nano-fibers of small diameter. 一种方法涉及让所述材料以熔融材料或以在随后蒸发的溶液中的形式通过细的毛细管或孔。 One method involves passing the material to the molten material in the form or in the subsequent evaporation of the solution through a fine capillary or orifice. 纤维还可以通过使用通常用于生产合成纤维如尼龙的"喷丝头"形成。 Fibers may also be produced by using commonly used synthetic fibers such as nylon "spinneret" is formed. 静电纺纱也是已知的。 Electrostatic spinning is also known. 这种技术涉及使用皮下注射器针头,喷嘴,毛细管或活动滴头。 This technique involves the use of a hypodermic needle, nozzle, capillary or active emitter. 所述结构提供了聚合物的液体溶液,其随后被高压静电场吸引到收集区。 The structure provides a liquid solution of the polymer, which is then attracted to a collection zone high voltage electrostatic field. 由于所述材料从所述发射体中被拉出并且加速通过静电区,所述纤维变得非常细,并能够通过溶剂蒸发形成纤维结构。 Since the material is pulled from the emitter and accelerate through the electrostatic zone, the fiber becomes very thin, and can form a fiber structure by solvent evaporation.

由于规章要求越来越严格,还需要工业集尘设备以除去加工空气流中较大比例的越来越小的颗粒。 Because of increasingly stringent regulatory requirements, industry needs to remove the dust-collecting apparatus smaller and smaller particles in the process air flow in a large proportion. 燃气轮机进气过滤系统同样必须除去大量非常小的颗粒,因为这些颗粒的存在可能导致对涡轮叶片无法挽回的破坏。 The gas turbine inlet air filtration system must be removed equally large number of very small particles, because of the presence of these particles may lead to irreparable damage to the turbine blades. 环境的清洁度,居住者的健康, 工业工艺的效率,工业设备的维护,以及生活的总体美观需要通过过滤器将亚微细粒材料容易地从空气流中除去。 Maintaining the cleanliness of the environment, the health of occupants, the efficiency of industrial processes, industrial equipment, and overall aesthetics of life need to submicron material easily removed from the air stream through the filter.

为了达到将亚微细粒通过所述系统从空气流中除去,惯性分离器倾向于只在颗粒材料的通道上设置物理障碍,所述颗粒材料然后从空气流中被碰撞进入收集箱。 In order to achieve the submicron removed from the air flow through the system, the inertia separator is provided only tend to physical barriers on the channel of the particulate material, the particulate material is then crashed into a collection box from the air stream. 纸袋集尘器只是基于袋形的纸过滤器技术的过滤器。 Bag filter dust collector is only based on a paper filter art pocket-shaped. 这种纸袋通常被简单地安装在空气流中,以便分离空气流中的颗粒。 Such paper is typically simply installed in the air flow, in order to separate particles in the air stream.

业已设计了更新的过滤器,其具有收集过滤器或平板或圆柱形滤芯。 It has been designed to update the filter, having a filter or collector plate or cylindrical cartridge. 在这些用途中,使用了HEPA过滤材料。 In these applications, the use of HEPA filter material. 通常这种HEPA结构包括延伸的PTFE (拉伸的特氟龙)层带有一层熔融吹制纤维结合在过滤器结构上,或者纤维素滤纸层带有一层熔融吹制纤维结合在过滤器结构上。 Such structure usually comprises PTFE HEPA extended (stretched Teflon) layer with a layer of melt-blown fibers bonded to the filter structure, cellulose filter paper or a layer with a layer of melt-blown fibers bonded to the filter structure . 这些结构通常仅通过轻敲过滤器或用压縮空气流将滤饼或颗粒物从过滤器吹掉进行清洁。 These structures generally only by tapping stream filter or filter cake or particles blown off with compressed air for cleaning the filter.

更新的过滤器的过滤效率和可清洁能力是重要的。 Updated filter filtration efficiency and cleaning ability is important. 这些过滤器必须能够除去灰尘和污物,但必须易于清洁而又不损坏过滤器。 These filters must be capable of removing dust and dirt, but it must be easy to clean without damaging the filter. 通常,在实心物体上轻敲过滤器以除去灰尘和污物可能造成过滤介质报废或可能造成多层成分分层,因此导致所述过滤器不能通过通道的形成使灰尘和污物通过过滤器结构。 Typically, a solid object in the tap filter to remove dust and dirt may cause the filter medium may result in a multilayer component or scrap delamination, thus resulting in the formation can not pass through the channel filter so that dust and dirt by a filter arrangement . 另一个失败的模式出现在当细的灰尘颗粒滞留在过滤介质中时,以至灰尘不能通过通常的过滤器清理机构去除,导致降低的真空功率和縮短的过滤器寿命。 Another failure mode occurs when in the fine dust particles retained in the filter medium, as well as dust can not pass through the filter cleaning mechanism is typically removed in vacuo resulting in reduced power and shortened filter life.

The term "nylon" is a polyamide condensation polymers name for all long chain synthetic polyamides. Typically, nylon nomenclature includes a

系列数字,如尼龙-6,6表示原始材料是C6 二元胺和C6 二酸(第一个数字表示C6 二 Series number, such as nylon-6,6 indicates the starting material is a C6 diamine and a C6 diacid (the first digit represents two C6

元胺,而第二个数字表示Q二羧酸化合物)。 Monoamines, and the second number denotes Q dicarboxylic acid compound). 另一种尼龙可在存在少量水的条件下由s己内酰胺的缩聚制成。 Another nylon can be made from the polycondensation of s-caprolactam in the presence of a small amount of water. 这种反应形成了尼龙-6 (由环状内酰胺-又被称作e-氨基己酸制成),其是线性聚酰胺。 This reaction forms a nylon-6 (prepared from the cyclic - also known as e- aminocaproic acid formed), which is a linear polyamide. 另外,还考虑了尼龙共聚物。 Further, nylon copolymers are also contemplated. 共聚物可通过在反应混合物中组合各种二元胺化合物,各种二酸化合物和各种环状内酰胺结构,然后在聚酰胺结构中形成带有随机定位的单体材料的尼龙。 Copolymers by combining various diamine compounds in the reaction mixture, various diacid compounds and various cyclic lactam structures within, and then forming the nylon with randomly positioned monomeric materials in a polyamide structure. 例如,尼龙6, 6-6, IO材料是由环己二元胺和C6和Cu) 二酸混合物制成的尼龙。 For example, nylon 6, 6-6, IO material is a mixture of a diamine and C6 cyclohexyl and Cu) diacid of nylon. 尼龙6-6, 6-6, 10是通过s氨基己酸, 环己二元胺和Q和C1Q 二酸材料的混合物共聚合而制成的尼龙。 Nylon 6-6, 6-6, 10 is formed by s-aminocaproic acid, a diamine and a mixture of cyclohexanone and Q co-C1Q acid material made of nylon polymerization.

嵌段共聚物在本发明的加工过程中同样有用。 Block copolymers are also useful in the process of the present invention. 对于这种共聚物来说,溶剂膨胀剂的选择是重要的。 For such copolymers, the choice of solvent swelling agent is important. 选择的溶剂使得两种嵌段都能溶解在所述溶剂中。 A solvent selected so that both blocks are soluble in the solvent. 一种例子是在二氯甲烷溶剂中的ABA (苯乙烯-EP-苯乙烯)或AB (苯乙烯-EP)聚合物。 One example is in a dichloromethane solvent ABA (styrene -EP- styrene) or AB (styrene -EP) polymer. 如果一种成分不溶解于所述溶剂,将会形成凝胶。 If one component is not dissolved in the solvent, will form a gel. 所述嵌段共聚物的例子是Kraton⑧型苯乙烯-b-丁二烯和苯乙烯-b-氢化丁二烯(乙烯丙烯),Pebax②型e-己内酰胺-b-乙撑氧,Sympatex®聚酯-b-乙撑氧和乙撑氧的聚亚氨酯和异氰酸酯。 Examples of the block copolymer is a styrene Kraton⑧ -b- -b- butadiene and styrene hydrogenated butadiene (ethylene propylene), Pebax② type e- caprolactam -b- ethylene oxide, Sympatex® polyester -b- ethylene oxide and ethylene oxide of polyurethane and isocyanate.

加聚物,如聚偏二氟乙烯,间同立构聚苯乙烯,偏二氟乙烯和六氟丙烯的共聚物,聚乙烯醇,聚醋酸乙烯酯,非晶型加聚物,如聚(丙烯腈),及其与丙烯酸和甲基丙烯酸酯的共聚物,聚苯乙烯,聚(氯乙烯)及其各种共聚物,聚(甲基丙烯酸甲酯)及其各种共聚物,能够比较容易地进行溶液纺丝,因为它们在低压和低温下可溶。 Addition polymers, such as polyvinylidene fluoride, syndiotactic polystyrene, copolymer of ethylene and vinylidene fluoride, hexafluoropropylene, polyvinyl alcohol, polyvinyl acetate, amorphous addition polymers, such as poly ( acrylonitrile) and its copolymers with acrylic acid and methacrylates, polystyrene, poly (vinyl chloride) and its various copolymers, poly (methyl methacrylate) and its various copolymers, can be relatively solution spun easily, since they are soluble at low pressures and temperatures.

27不过,诸如聚乙烯和聚丙烯的高度晶体状聚合物需要高温、高压溶剂,如果对它们进行溶液纺丝的话。 27, however, such as polyethylene and polypropylene, highly crystalline polymers require high temperature, high pressure solvent if they are to be solution spun words. 因此,聚乙烯和聚丙烯的溶液纺丝是非常困难的。 Therefore, solution spinning of the polyethylene and polypropylene is very difficult. 静电溶液纺丝是制造纳米纤维和微纤维的一种技术。 Electrostatic solution spinning is a technique for producing nanofibers and microfibers.

横向流动膜过滤技术利用流体成分的分离,通过半透膜,通过对所述膜表面施加压力和切向流。 Lateral flow membrane filtration techniques utilize separate fluid components through a semipermeable membrane, by applying pressure to the film surface and tangential to the stream. 这包括R/0, UF,纳米过滤和微孔过滤工艺。 This includes R / 0, UF, nanofiltration, and microfiltration processes. 基本上,与引导所有流体流过过滤介质(闭端流动)不同,所述流体流经薄膜材料;某些流体流过所述薄膜材料(不是太多-也许大约10%),因此在其余的液体流中集中污染物。 Basically, all of the fluid flow guide through the filter media (dead end flow) different from the fluid flowing through the thin film material; some of the fluid flow through the film material (not many - perhaps about 10%), and therefore the remaining concentration of contaminants in the liquid stream. 所流经的液体流还能从介质表面上排出任何颗粒,因为薄膜(和纳米纤维)表面加载了碎屑, 并且流动的液体的剪切力足够排出所述颗粒。 The liquid stream also flows through the discharging any particles from the surface of the medium, since the film (and nanofibers) debris loaded surface, and a shearing force sufficient to discharge the flow of the liquid particles. 这类系统被用于各种场合-有时带集中碎屑的流体流实际上是产品(生化或制药加工);在其他场合下,集中所述碎屑导致较小体积的流出物被处理/保存。 Such systems are used in various applications - sometimes with debris concentrated fluid stream is in fact the product (biochemical or pharmaceutical processing); in other cases, the chip results in smaller volume concentration of the effluent to be treated / stored . 有时候所述系统还使用反向脉冲或振动清洁技术, 排除"固体物"。 The system also sometimes using a reverse pulse cleaning technique or vibration, to exclude "solids." 这些过滤器通常被用于获得或集中有价值的盐,蛋白,药品等,并且通过分子大小区分和分离。 These filters are typically used to obtain a concentration value or a salt, proteins, drugs, etc., and by differentiation and separation of molecular size. 采用合适的冲洗技术,可以延长过滤器寿命并且控制成本。 Using a suitable rinsing technique, you can extend the life of the filter and control costs. 因为薄膜过滤器将颗粒限制在源侧,可以通过改变流动方向(逆流)冲洗过滤器。 Because the membrane filter limits the particles at the source side, by changing the direction of flow (countercurrent) flush the filter. 很多薄膜过滤器以横向流动为特征,其中大部分流体切向运动到所述表面,以清除污染物,并且避免阻塞过滤器。 Many lateral flow membrane filter is characterized most of the fluid tangential movement to the surface, to remove contaminants, and to avoid clogging of the filter. 只有小部分(大约10%)的流体作为净化的渗透通过过滤器。 Only a small portion of the fluid (approximately 10%) of the permeate as a purge through the filter. 流动通过过滤器,如筒式过滤器,所述颗粒更难排除,因为它们更深地渗透到过滤器中心,通常扔掉所述过滤器并且换个新的过滤器比试图更新所述过滤器更省钱。 Flow through the filter, such as a cartridge filter, the harder particles excluded as they penetrate deeper into the center of the filter, the filter is usually thrown away and another new filter updates the filter more than trying to save money. 以横向流动模式操纵过滤器或滤膜有助于污染物排除和价值回收过程。 Manipulator lateral flow pattern in the filter or filters to exclude contaminants and helps value recovery process. 通过这样做,被排除的污染物或有价值的材料被从所述薄膜表面连续带走,从而减少了集中层的形成,并且使所述膜不会排斥进入的材料,保持高流动,并且允许液体自由地流动。 By doing so, contaminants are excluded or valuable materials are continuously carried away from the surface of the film, thereby reducing the concentration layer is formed, and the film does not repel the incoming material flow remains high and allows liquid flow freely. 尽管需要对薄膜进行定期清洁,横向流动过滤的自动清洗性质使所述薄膜具有在经济上吸引人的薄膜使用寿命。 While the film needs regular cleaning, self-cleaning properties of the cross flow filtration film having a film life is economically attractive.

横向流动操作通常属于三种类型中的一种:超滤(UF),纳米过滤(NF), 和超过滤,更常见的是被称作反渗透(RO)。 Transverse flow of operation usually belonging to one of three types: Ultrafiltration (the UF), nanofiltration (of NF), ultrafiltration and, more commonly referred to as reverse osmosis (RO). 这三种类型中最常用的是反渗透,因为它具有分解杂质或回收有价值的固体材料的综合能力。 These three types of reverse osmosis is the most commonly used, because of its comprehensive capacity of recovering valuable decomposing impurities or solid material. 机器通常包括薄膜部件和外壳,相互连接的管子,泵,前置过滤器,控制器以及操作所需要的仪器。 Machines typically include a thin film member and the housing, interconnected tubes, pumps, pre-filter, the controller and the equipment required for the operation.

由于膜占RO或UF仪器价值的15-40%,并且必须定期更换,因此需要仔细选择。 As the film accounted for 15-40% RO or instrument value UF, and must be replaced on a regular basis, and therefore need to be carefully selected. 有多种类型的膜可供使用,并且每一种具有它自身的独特特征。 There are several types of films are available, and each has its own unique characteristics. 选择标准应当包括化学耐受性,机械适宜性,可清洁性,分离,和流动性能和价格。 Selection criteria should include chemical resistance, mechanical suitability, cleanability, separation, and flow performance and price.

对于其他机械装置来说,横向流动过滤仪在设计和材料彼此增强时功能最佳。 For other mechanical means, the lateral flow filtration device materials and design functions best when the reinforcing each other. 一旦选择了正确的薄膜,能提供合适的横向流动速度,压力和渗透后回收的设计成为关键。 Once the correct choice of film, provides proper lateral flow rate, pressure, and permeate recovery after a key design. 废水比常见饮用水具有更高的起垢倾向,并且需要更保守的设计。 Waste water has a higher tendency than the usual dirt from the drinking water, and require more conservative design. 好的机器设计优点应该是一致的操作和分离性能,最低的薄膜清洁和更换频率,合理的能量消耗和对操作注意的最低要求。 Good machine design should be the same advantage and operation of separation performance, the lowest frequency of cleaning and replacement of the thin film, a reasonable energy consumption and minimum requirements for the operation noted.

可能没有比制备膜处理给水设备更好的投资。 Investment may not be better than a film treated feedwater preparation apparatus. 所述设备相对便宜,但仍具有极大的优点。 The apparatus is relatively cheap, but still has a great advantage. 例如,多介质过滤器能够非常有效地除去浑浊度和氧化金属(如铁和锰)。 For example, multi-media filters can be effective for removing turbidity and oxidized metal (such as iron and manganese). 筒式或袋式过滤器能除去大约五微米的残余不溶性材料是必须。 Cartridge or bag filters can remove about five microns residual insoluble material is necessary. 化学物泵对注入酸或阻招剂有用,以保持盐的可溶性或用于生物控制剂的注入。 Useful for chemical injection pump strokes blocking agent or an acid, in order to maintain the injection of soluble salts or a biological control agent. 根据给水的性质,其他设备诸如澄清器或碳过滤器同样适用。 Depending on the nature of the feed water, the clarifier or other devices are equally applicable, such as a carbon filter.

由于良好的预处理,横向流动机器中的薄膜不会承受超过它设计的负荷。 Because of the good pre-treatment, the lateral flow membrane in the machine is not subjected to loads beyond its design. 其结果是在用户方面能取得最佳性能,和最低的总体支出。 The result is to achieve the best performance, and the lowest total expenditure in terms of users. 如何确定正确的膜和合适的设计和预处理,是用一种应用和试验性的程序开发所述用途。 How to determine the correct film and suitable design and pretreatment, the purpose is to develop an application program and experimental. 应用试验,或可行性试验, 是确定所述机器特征的第一个步骤。 Application test, or feasibility test, the machine is characterized by a first step of determining. 通常是在实验室或工作台规模进行,所述应用试验表明了试验薄膜类型的杂质排除力,化学物适宜性,和起垢倾向的预期水平。 Is usually carried out in a laboratory or bench scale, the application of the test film tests showed negative force-type impurity, chemical suitability, and the expected level of from fouling tendencies. 结果通常足够可靠,以将膜的选择缩小到不超过两种,并且预测是否需要任何预处理设备。 Typically results reliable enough to select the film is reduced to no more than two, and predict whether any pretreatment equipment.

在应用试验中获得的信息随后可应用于现场先期测试。 The information obtained in the application of the test can then be used on-site pilot testing. 用几百个小时进行的先期测试可以收集到稳态性能数据,用于全面设计。 Early tests with hundreds of hours of steady state performance data can be collected for a comprehensive design. 给水化学,清洁频率和技术效果的变化在决定稳态操作方面发挥重要作用。 Chemical changes in water supply, clean technology and frequency effects play an important role in determining the steady-state operation.

在应用开发和设备购买方面与有经验的公司合作的重要性再强调也不为过。 The importance of cooperation in the application development and equipment purchases with an experienced company and then can not be overemphasized. Waste

水应用是独特的,个性化处理需要有效的评估和对工艺参数的微调,横向流动过滤技 Application of water is unique, and effective evaluation and fine-tuning process requires personalization of process parameters, cross flow filtration technique

术供应商和消费者之间的密切配合能取得最佳效果。 Close cooperation between the suppliers and consumers of surgery can achieve the best results.

图2表示在三次灰尘加载和清洁周期之后,每个样品的重量增加。 Figure 2 shows three after dust loading and cleaning cycles, increase in weight of each sample. 重量增加表明灰尘被留在样品中,并代表一定量的灰尘不能通过常用的过滤器清洁机制从材料上清理掉。 Weight increase showed that the dust is left in the sample, and represents the amount of dust can not be used by the filter cleaning mechanism to clean out from the material. 本示例的材料和PTFE材料与玻璃纤维HEPA材料相比均表现出适度重量增加。 Material and the PTFE material of this example as compared with a glass fiber HEPA material exhibited moderate increase in weight.

Per minute to provide a reverse pulse of 40psi for 100 msec pulse cleaned filters typically reaching the final pressure drop to be replaced, Example 3 medium lower pressure drop than glass fiber HEPA showed no nanofibers, which has better cleanability and longer filter life.

图9比较了在脉冲实验之前和之后玻璃纤维HEPA和例3介质的效率。 Figure 9 compares the test pulse before and after the efficiency of glass fiber HEPA medium and Example 3. 该图表明了脉冲作用不会降低所述介质的效率。 The graph shows the pulsed without decreasing the efficiency of the medium. 这个结果是令人吃惊的,因为脉冲压力和介质运动被认为会导致微纤维玻璃纤维分离,可能产生空隙,并最终降低介质的效率。 This result is surprising, since the pulse pressure and medium motion is believed to result microfiber glass fiber separation, it may be a void, and ultimately reduce the efficiency of the media. 这一看法被证实是不正确的,并且对于玻璃纤维HEPA材料和例3的介质来说都保持了HEPA的效率。 This view proved to be incorrect, and for materials and glass fiber HEPA medium of Example 3 is maintained in the efficiency of HEPA.
