    常州工业废气治理

     
    在橡胶轮胎生产过程中,会产生一定量得橡胶轮胎废气。这种废气的污染因子主要为工业粉尘、恶臭等污染物,虽然污染强度不大,但是废气排放量大、污染成分复杂多变,尤其是废气中恶臭成分对周围环境、厂区环境造成一定的污染,扰民现象难以避免。  轮胎生产废气的主要成分:橡胶轮胎废气的臭气成分复杂多变。大致可分成5类:
          1)、含硫的化合物:如H2S、SO2、硫醇类、类;
          2)、 粉尘类:如碳黑;
          3)、含氯的化合物:如酰胺、吲哚类;
          4)、烃类:如烷烃、烯烃、烃、芳香烃;
          5)、含氧的有机物,如醇、酚、醛、酮、有机酸等。
    其中无机物有H2S、SO2、炭黑等,绝大多数恶臭气体产生的原生物质为有机物质。这些物质对人体健康危害较大。  从上述橡胶轮胎制造工艺各道工序中可以了解到橡胶轮胎废气的主要产生环节是炼胶和硫化两个工序。
    (一)炼胶工序:炼胶包括塑炼和混炼。
    塑炼:是为了满足各种加工工艺过程对胶料可塑度得要求,通常在一定条件下对生胶进行机械加工,使之由强韧的弹性状态转变为柔软而具有可塑性的状态,这个工 艺过程称为塑炼。  混炼:是将塑炼胶或者具有一定可塑性的橡胶与配合剂在机械作用下混合均匀,制成胶料,以便制造具有各种性能的橡胶制品。 配合剂与胶料的混炼工艺过程可分为四个阶段:混入、分散、混合和塑化。  橡胶轮胎厂炼胶量大,在炼胶时需要将各种配合剂和生胶加入密炼机的进料口中,因此在此过程中会产生一定量的原料泄露和一定量的粉尘泄露。而在密炼机的出料 口也会产生大量废气,除了烟尘和水蒸气外,还含有油类混合物,包括乳化油和乳油。其中乳化油的油珠粒径小于10微米,一般为0.1-2.0微米。气体中含 有表面活性剂,使油珠成为稳定的乳化液,停留在管道就会形成油状物,长期积累的油泥状物直接排向大气就会使周围物体表面积附油垢。  炼胶废气中主要污染物含有粉尘、硫化氢、二硫化碳、甲苯、非总烃。
    (二)硫化工序
    硫化就是将具有一定塑性和黏性的胶料经过成型工艺后而制成的胶辊半成品在一定外部条件下通过化学因素(如硫化体系)的作用,重新转化为软质弹性橡胶制品或 硬质韧性橡胶制品,从而获得使用性能的工艺过程。在硫化过程中,外部的条件使胶料组分中的混炼胶与硫化剂发生化学反应,由线形的橡胶大分子交联成立体网状结构的大分子,从而大大改善了橡胶的各项性能,使橡胶胶辊获得了能满足产品使用需要的硬度、耐热、耐老化、耐酸碱、耐高温、弹性等物理机械性能和其他性 能。硫化的实质是交联,即线形的橡胶分子转化为空间网状结构过程。硫化分为四个阶段:焦烧阶段、热硫化阶段(欠硫期-预硫阶段)、硫化平坦阶段(正硫期- 正硫化阶段)、过硫阶段(过硫期)硫化过程中使用的硫化剂分为无机和有机两大类。前一类有硫磺、一氯化硫、硒、碲等。后一类有含硫的促进剂(如促进剂 TMTD)、有机过氧化物(如醌肟化合物、多硫聚合物、甲酸乙酯、马来酰亚胺衍生物等。  橡胶硫化剂包括元素硫、硒、碲,含硫化合物,过氧化物,醌类化合物,胺类化合物,树脂类化合物,金属氧化物以及异氰酸酯等。用得最普遍的是元素硫和含硫化 合物。  因此硫化过程中产生的废气主要成分为含硫化合物、含氧有机物、烃类等。
    橡胶废气、橡胶硫化烟气危害比较大,废气成分含有恶臭物质,并随着风向远距离飘飘逸,在空气中停留时间长。造成各种不良影响。因此,需要进行有效收集并做净 化处理,以确保企业生产运行良好及改善车间及厂区环境、达到国家环保要求。
    高级氧化技术是对传统处理技术中的经典化学氧化法,在改革的基础上应运而生的一种新技术方法,他由GLAZEW.H,等人1987年提出,高级氧化技术 advanced OxidationProcesses简称AOP。指羟基自由基(OH)使难降解的污染物氧化成CO²、H2O和无害羧酸,接近完全矿化。它是最有前景的 处理难降解污染物的方法。
    LTAOP废气处理技术作用机理
    等离子发生器产生带有强氧化性O、O3等氧化性物质在催化剂的作用下产生大量羟基自由基(OH),O3参与直接反应,OH参与简介反应在PH﹥4条件下90%由间接反应完成,特别是对异臭气体的分解,在直接和间接反应后分解率达95%以上。

    Professional treatment equipment for industrial waste gas treatment

    At the end of the 90s of last century, a writer once returned to South of Jiangsu's home and wrote that the sight of the clear river in the eight towns in four townships was gone. To my surprise, the main factor contributing to this situation is industrial waste. China's development in recent years is indeed great, and the industrial production effect has also increased a lot. How to deal with these industrial wastes? It
    It
    For the sake of our ecological environment and my health, we rely on scientific research institutions, university colleges and universities to absorb and utilize them. Different kinds of organic waste gas treatment equipment have been developed. These waste gas treatment equipment are: water forest tower, low temperature plasma, UV photolysis air purifier, activated carbon adsorption equipment and other organic waste gas treatment equipment.

    Water drenching tower, also known as exhaust gas purification tower. The working principle of the waste gas treatment equipment is to separate the pollutants from the gas and convert them into harmless substances so as to achieve the purpose of purifying the gas.
    Activated carbon adsorption is the use of activated carbon physical adsorption, chemical adsorption, oxidation, catalytic oxidation and reduction and other properties to remove pollutants in the gas.
    The UV photolysis air purifier is a device which uses special high-energy and high ozone UV ultraviolet beam to irradiate odorous gas to crack malodorous gas.
    Low temperature plasma is the use of high-energy electrons, free radicals and other active particles activated, ionized, pyrolysis of each component of industrial waste gas.
    These are all industrial waste gas treatment equipment. Can effectively deal with exhaust gas, so as to achieve the purpose and protect our environment. China has a long way to go in dealing with pollution problems. It needs to act in accordance with the law to stop the occurrence of vicious environmental incidents and delay the deterioration of the environment.

    In the process of rubber tire production, a certain amount of rubber tire exhaust gas will be generated. The pollution factors of this kind of waste gas are mainly industrial dust, odor and other pollutants. Although the pollution intensity is small, the emission of waste gas is large and the pollution components are complex and changeable. Especially, the odor components in the waste gas have caused certain pollution to the environment and the environment of the factory area, and the phenomenon of disturbing people is difficult to avoid. The main components of tire exhaust gas: rubber tire exhaust odor ingredients are complex and changeable. It can be divided into 5 categories:
    1) sulfur compounds: H2S, SO2, mercaptan, and so on.
    2), dust category, such as carbon black;
    3) chlorinated compounds such as amide and indole.
    4) hydrocarbons, such as alkanes, olefins, hydrocarbons and aromatic hydrocarbons.
    5) oxygen containing organic compounds such as alcohols, phenols, aldehydes, ketones, organic acids, etc.
    Inorganic substances include H2S, SO2, carbon black and so on. Most of the malodorous gases produce organic matter. These substances are harmful to the health of the human body. From the above rubber tire manufacturing process, we can understand that the main production process of rubber tire exhaust is two processes: rubber mixing and vulcanization.
    (1) rubber mixing process: Rubber making, including plastic mixing and mixing.
    Plastics: in order to meet the requirements of the plastic plasticity of various processing processes, the mechanical process of the raw rubber is usually processed under certain conditions to make the flexible state of elasticity transformed into a soft and plastic state. This process is called plastic. Mixing: it is a mixture of plastic or rubber with a certain plasticity under mechanical action and made into rubber to make rubber products with various properties. The mixing process of mixture and binder can be divided into four stages: mixing, dispersing, mixing and plasticizing. Rubber tire factory has a large amount of rubber, and in the process of refining, various additives and raw rubber should be added into the inlet of the mixer, so a certain amount of material leakage and a certain amount of dust leakage will be produced in this process. In the mixer outlet, there will also be a lot of waste gas. Besides smoke and steam, it also contains oil mixture, including emulsified oil and emulsifiable concentrate. Among them, the diameter of emulsified oil beads is less than 10 microns, generally 0.1-2.0 microns. The gas contains surfactant to make the oil bead a stable emulsion, and the oil will form in the pipeline. The long accumulated oil sludge will be directly discharged into the atmosphere, and the surface area of the surrounding objects will be attached to the oil. The main pollutants in rubber exhaust include dust, hydrogen sulfide, carbon disulfide, toluene and non total hydrocarbon.
    (two) vulcanization process
    Vulcanization is a semi finished rubber roll made of plastic and adhesive material after forming process. Under certain external conditions, through chemical factors (such as vulcanization system), it is reconverted into soft elastic rubber products or hard ductile rubber products, thus obtaining the process of performance. In the process of vulcanization, the external conditions cause the chemical reaction between the rubber and the vulcanizing agent in the rubber component, and the linear rubber macromolecules are crosslinked into the large molecules of the three-dimensional reticular structure, which greatly improves the properties of the rubber, and makes the rubber cots obtain the hardness, heat resistance, aging resistance that meet the needs of the products. Acid and alkali resistance, high temperature resistance, elasticity and other physical and mechanical properties and other properties. The essence of vulcanization is cross-linking, that is, the linear rubber molecule is transformed into a space net structure. The vulcanization is divided into four stages: the scorching stage, the hot vulcanization stage (the sulfur under sulfur phase), the flat phase of vulcanization (the sulphur phase - vulcanization stage) and the sulphur over phase (sulfur over period) are divided into two kinds of inorganic and organic compounds. The first category is sulfur, sulfur chloride, selenium, tellurium and so on.  The latter type has sulfur containing accelerators.
