Description
技术领域technical field
本发明涉及废气处理技术领域，尤其是一种橡胶轮胎生产废气综合处理系统。The invention relates to the technical field of waste gas treatment, in particular to a comprehensive waste gas treatment system for rubber tire production.
背景技术Background technique
随着经济的提升我国的汽车工业也高速发展，与其相关联的橡胶轮胎业也发展迅速。橡胶轮胎生产过程产生的工业废气以多种方式排放到环境中，破坏了自然环境，威胁人类的健康与生存发展。橡胶行业产生废气和其生产的工艺有着不可分割的联系。通常生胶如天然、氯丁、顺丁、丁苯橡胶等，在正常的储存和使用条件下不会产生毒害作用。然而生胶在炼胶、压延、硫化等工序的高温塑炼和氧化过程中，容易产生有害的物质，与此同时，原材料中沸点较低的物质也能够被释放出来，从而发生一系列化学反应产生一定量的废气，且伴随有难闻的恶废气味。橡胶工业废气中还有挥发出的有机溶剂，有机溶剂的主要作用是对胶布、胶片等半成品的表面进行涂试，从而达到活化、去污、增粘等作用，但其具有较低的沸点，易挥发，在加热干燥或者自然条件下汽化后排放在空气中。橡胶工业废气主要组成成分是硫化物、水蒸气以及具有挥发性质的有机化合物。挥发性有机化合物(VOC)和硫化物是主要的产生恶臭的物质。With the improvement of the economy, my country's automobile industry is also developing rapidly, and the rubber tire industry associated with it is also developing rapidly. The industrial waste gas produced in the rubber tire production process is discharged into the environment in various ways, destroying the natural environment and threatening human health, survival and development. There is an inseparable relationship between the waste gas produced by the rubber industry and its production process. Usually raw rubber such as natural, chloroprene, cis-butadiene, styrene-butadiene rubber, etc., will not produce toxic effects under normal storage and use conditions. However, raw rubber is prone to produce harmful substances during the high-temperature plasticizing and oxidation processes of rubber mixing, calendering, vulcanization and other processes. At the same time, substances with lower boiling points in the raw materials can also be released, resulting in a series of chemical reactions. A certain amount of waste gas is produced, accompanied by an unpleasant smell of waste. There are also volatilized organic solvents in the waste gas of the rubber industry. The main function of organic solvents is to coat the surface of semi-finished products such as tapes and films, so as to achieve activation, decontamination, and thickening. However, they have a low boiling point. Volatile, it will be released into the air after being heated and dried or vaporized under natural conditions. The main components of rubber industry waste gas are sulfides, water vapor and volatile organic compounds. Volatile organic compounds (VOCs) and sulfur compounds are the main malodorous substances.
橡胶工业废气控制是以废气中的挥发性有机物和硫化物作为处理对象，橡胶工业废气的处理方法有吸附法、氧化法、吸收法和生物法。吸附法是一种有效的处理低浓度挥发性有机化合物的方法，其主要原理是利用吸附剂对VOC进行吸附净化，之后再将气体排放在大气环境中。氧化法可以分为直接燃烧和催化燃烧，其降解机理主要是高温氧化、热分解和热裂解。直接燃烧法是利用高温直接氧化VOC，在足够高的温度、过量空气和湍流条件下进行完全燃烧。催化燃烧法在催化剂的作用下，使有机废气中的碳氢化合物在温度较低的条件下迅速氧化成水和二氧化碳，达到治理的目的。吸收法是利用VOC的化学性质和物理性质，用化学吸收剂或水与废气进行充分接触而将其中的可溶于该吸收液的VOC从废气中分离出来进入吸收液的过程。生物法的基本原理是先将废气在湿度控制器中加湿处理，然后令其通过生物滤床的布气板，废气沿着滤料向上均匀的移动，气相物质通过吸附、扩散效应、平流效应等综合作用和滤料表面的活性生物层中的微生物产生反应，实现生物降解形成水和二氧化碳。The rubber industry waste gas control is based on the volatile organic compounds and sulfides in the waste gas. The rubber industry waste gas treatment methods include adsorption, oxidation, absorption and biological methods. Adsorption is an effective method for treating low-concentration volatile organic compounds. Its main principle is to use adsorbents to adsorb and purify VOCs, and then discharge the gases into the atmosphere. The oxidation method can be divided into direct combustion and catalytic combustion, and its degradation mechanism is mainly high temperature oxidation, thermal decomposition and thermal cracking. The direct combustion method uses high temperature to directly oxidize VOC, and complete combustion is carried out under sufficiently high temperature, excess air and turbulent conditions. Under the action of a catalyst, the catalytic combustion method makes the hydrocarbons in the organic waste gas rapidly oxidize into water and carbon dioxide at a low temperature, so as to achieve the purpose of treatment. The absorption method is the process of using the chemical and physical properties of VOC to fully contact the exhaust gas with a chemical absorbent or water to separate the VOC soluble in the absorption liquid from the exhaust gas into the absorption liquid. The basic principle of the biological method is to humidify the waste gas in the humidity controller first, and then let it pass through the air distribution plate of the biological filter bed. The waste gas moves upwards evenly along the filter material, and the gas phase substances pass through adsorption, diffusion effect, advection effect, etc. The combined effect and the microorganisms in the active biological layer on the surface of the filter material react to achieve biodegradation to form water and carbon dioxide.
橡胶轮胎生产废气成分复杂，采用上述单一的方法很难实现达标排放。The composition of exhaust gas from rubber tire production is complex, and it is difficult to achieve standard emission by using the above-mentioned single method.
