Description
技术领域technical field
本实用新型涉及一种生物-吸附一体式化工废气处理设备，用于石油化工、化工制药、建材、有机合成等行业化工车间产生的化工废气处理，属于环境保护技术领域。The utility model relates to a biological-adsorption integrated chemical waste gas treatment equipment, which is used for the treatment of chemical waste gas produced in chemical workshops in petrochemical, chemical pharmaceutical, building materials, organic synthesis and other industries, and belongs to the technical field of environmental protection.
背景技术Background technique

Chemical waste gas will seriously interfere with the daily life of residents and cause serious harm to human health and the ecological environment. With the development of society and economy, the improvement of living standards and the increasing public environmental awareness, the treatment of chemical waste gas has attracted more and more attention. .
目前，化工废气的处理方法主要有吸收法、吸附法、催化法、焚烧法、冷凝法和生物法等。但对于中低浓度有机废气，吸收法和吸附法等物理化学方法存在着工艺复杂、投资及运行费用高、易造成二次污染等缺点。与常规的物化处理方法相比，生物法具有处理效果好、无二次污染、投资及运行费用低、易于管理等优点，特别适用于大流量、中低浓度有机废气的处理。研究资料表明，生物处理方法的投资和运行费用仅为物化法的1/4～1/20，运用生物方法处理中、低浓度化工废气已成为国内外研究和应用的热点之一。At present, the treatment methods of chemical waste gas mainly include absorption method, adsorption method, catalytic method, incineration method, condensation method and biological method. However, for medium and low concentration organic waste gas, physical and chemical methods such as absorption method and adsorption method have disadvantages such as complex process, high investment and operating costs, and easy to cause secondary pollution. Compared with conventional physical and chemical treatment methods, the biological method has the advantages of good treatment effect, no secondary pollution, low investment and operating costs, and easy management. It is especially suitable for the treatment of large flow, medium and low concentration organic waste gas. Research data show that the investment and operating costs of biological treatment methods are only 1/4 to 1/20 of that of physical and chemical methods, and the use of biological methods to treat medium and low concentration chemical waste gas has become one of the hot spots of research and application at home and abroad.
然而由于化工生产过程中产生的废气物质浓度变动大，组分较为复杂，除可能含有硫化氢和氨等无机物质外，还可能含有苯系物、烃类、醛酮类、卤代烃和醇类物质。特别是含硫、氨气体生物降解过程中产生的酸性物质易导致生物处理系统pH降低，从而引起系统处理效率降低和运行不稳定等问题。可见，常规废气处理设备在处理化工废气时，存在着处理效率低、很难实现达标排放和系统运行不稳定等不足。However, due to the large changes in the concentration of waste gas produced in the chemical production process, the components are relatively complex. In addition to inorganic substances such as hydrogen sulfide and ammonia, it may also contain benzene series, hydrocarbons, aldehydes and ketones, halogenated hydrocarbons and alcohols. class of substances. In particular, the acidic substances produced during the biodegradation of sulfur and ammonia gases can easily lead to a decrease in the pH of the biological treatment system, resulting in problems such as reduced system treatment efficiency and unstable operation. It can be seen that when conventional waste gas treatment equipment treats chemical waste gas, there are shortcomings such as low treatment efficiency, difficulty in achieving standard discharge, and unstable system operation.

本实用新型解决其技术问题所采用的技术方案是：一种生物-吸附一体式化工废气处理设备，由生物过滤区、气体缓冲区、气体干燥区和活性炭吸附区组成。化工废气首先经过气体分布管和气体分布板均匀分布后进入生物过滤区，在生物过滤区内发生生物吸收和降解反应。生物过滤区出气经气体缓冲区缓冲后进入气体干燥区，除去气体中的水分，干燥后的气体进入活性炭吸附区，经活性炭颗粒吸附后，尾气经设置在活性炭吸附区中的出气口排放。The technical solution adopted by the utility model to solve the technical problem is: a biological-adsorption integrated chemical waste gas treatment equipment, which is composed of a biological filter area, a gas buffer zone, a gas drying area and an activated carbon adsorption area. The chemical waste gas is first uniformly distributed through the gas distribution pipe and the gas distribution plate, and then enters the biological filtration area, where biological absorption and degradation reactions occur. The gas out of the biofiltration area is buffered by the gas buffer and enters the gas drying area to remove the moisture in the gas. The dried gas enters the activated carbon adsorption area. After being adsorbed by activated carbon particles, the tail gas is discharged through the gas outlet set in the activated carbon adsorption area.
