pp聚丙烯吸收塔技术的分类

Classification of PP absorption tower technology

近年来，我***医药化工行业发展迅速，已成为世界上原料药和医药中间体的生产******，其产生的废气污染物***致分为发酵尾气(主要为酸性气体)、溶剂气体(统称为挥发性有机物，VolatileOrganicCompounds，以下简称为VOCs)和恶臭气体。医药生产的废气主要***点为排放量***，浓度低，处理成本高。随着各***对环境质量要求的不断提高，对废气排放规定了严格的排放界限值。

In recent years, China's pharmaceutical and chemical industry has developed rapidly, and has become the world's largest producer of APIs and pharmaceutical intermediates. The waste gas pollutants produced by it can be roughly divided into fermentation tail gas (mainly acid gas), solvent gas (collectively referred to as volatile organic compounds, VOCs, hereinafter referred to as VOCs) and odor gas. The main characteristics of waste gas from pharmaceutical production are large emission, low concentration and high treatment cost. With the continuous improvement of environmental quality requirements in various countries, strict emission limits have been set for exhaust emissions.

药厂废气主要是乙醇，属于VOCs，由于乙醇中的碳氢化合物，会在阳光(紫外光)作用下发生光化学反应生成二次污染物，形成烟雾污染现象。***量的VOCs气体排放会对环境及人群都会产生不***影响。为此   废气净化塔厂家对废气进行净化处理，消除光化学烟雾的隐患后才可排放。

The waste gas of pharmaceutical plants is mainly ethanol, which belongs to VOCs. Due to the hydrocarbons in ethanol, photochemical reaction will occur under the action of sunlight (UV) to generate secondary pollutants, which will form smoke pollution. A large number of VOCs emissions will have adverse effects on the environment and people. For this reason, the manufacturer of the waste gas purification tower should purify the waste gas and eliminate the hidden dangers of photochemical smoke before discharging.

随着时代和科技的发展，废气处理工艺也经历着不断发展的过程。目前有机废气的净化方法，从初采用的水洗法，逐步发展出一系列的方法并且已在工业生产中获得成功应用。按其工作原理，酸雾净化塔厂家把它分为物理、化学、生物等净化方法，即：

With the development of the times and science and technology, waste gas treatment technology is also experiencing a continuous development process. At present, the purification method of organic waste gas, from the initial water washing method, has gradually developed a series of methods and has been successfully applied in industrial production. According to its working principle, the acid mist purification tower manufacturer divides it into physical, chemical and biological purification methods, namely:

(1)热力学方法

(1) thermodynamic method

例如冷凝、吸收、吸附和膜分离等(吸附和吸收可以是化学或物理的)。

For example, condensation, absorption, adsorption and membrane separation (adsorption and absorption can be chemical or physical).

(2)化学方法

(2) chemical methods

例如燃烧法，即氧化法(直接燃烧、热力燃烧、催化燃烧、蓄热式热力燃烧)

For example, combustion, i.e. oxidation (direct combustion, thermal combustion, catalytic combustion, regenerative thermal combustion)

(3)生化方法(也称生物降解法或生物催化法)

(3) biochemical method (also known as biodegradation method or biocatalysis method)

例如：生物过滤、生化洗涤和生化膜分离等。

For example: biological filtration, biochemical washing and biochemical membrane separation.

环保、经济而论，如果VOCs的价值较高，而且有可能回收，则应尽可能将其回收在利用，因此从这意义上讲，有机废气的净化方法也可分为：

In terms of environmental protection and economy, VOCs should be recycled as much as possible if its value is high and it is possible to recycle. Therefore, the purification methods of organic waste gas can also be divided into:

(1)回收法

(1) recovery method

例如吸附分离法，冷凝法和膜分离法等。

For example, adsorption separation, condensation and membrane separation.

(2)转化法(又称破坏法)

(2) transformation method (also known as destruction method)

将VOCs转化为无害物质，例如燃烧法和生化法。

VOCs are converted into harmless substances, such as combustion and biochemical methods.
