Description
Technical Field

Background
Atmospheric pollution is one of the most outstanding environmental problems in China at present, and industrial waste gas is an important source of atmospheric pollutants. The most harmful and difficult to treat industrial waste gas is organic waste gas; the composition of organic waste gas is different in different industries, and different requirements are also imposed on treatment methods and devices. The existing organic waste gas treatment methods are mainly divided into two types: a recovery method and a cancellation method. The recovery method is to select proper adsorbent and selective permeable membrane under certain conditions to separate volatile organic pollutants. The elimination method is a method of converting pollutants into water and carbon dioxide by chemical or biological reaction, and includes thermal oxidation, catalytic combustion, biological oxidation, corona method, plasma decomposition method, photo decomposition method, etc. The general industrial waste gas adopts a strategy of recycling and then eliminating.
At present, the traditional methods for treating waste gas include combustion method, absorption method, biological method, photocatalysis method, low-temperature plasma method, adsorption method and the like.
Among the recovery methods, the adsorption method is most commonly used. The choice of the adsorbent plays a decisive role in the adsorption efficiency. At present, the adsorbent mainly comprises granular or honeycomb activated carbon, activated carbon fiber, molecular sieve, silica gel, high polymer adsorption resin and the like. Activated carbon is commonly used because of its high surface area, large adsorption capacity and low price. However, activated carbon has a disadvantage that it does not resist high temperature and cannot maintain good adsorption capacity under wet conditions. The activated carbon fiber has the characteristics of large specific surface area, small thermal capacity, high adsorption and desorption speed, low energy consumption and the like, and is a popular novel adsorbent; the adsorption efficiency is very high, according to the content of organic gas in the treated waste gas and different physical characteristics, the adsorption efficiency is between 85% and 98%, the multistage adsorption process can reach 99.99%, the maximum adsorption rate is far higher than 88% of the activated carbon particle adsorption method, and the volume and the total weight are very small; however, the price is too high, and it is difficult to treat organic waste gas with high humidity, so the application is limited.
Most of the existing adsorbents in the adsorption method are solids with porous structures, but because the solids are in the process of adsorbing impurities in waste gas, the outer surface of the porous solid adsorbent always contacts with the waste gas first, so that for the whole adsorbent, the adsorption capacity of the outer layer is weaker and weaker along with the prolonging of the service time, and the pore diameter of the outer layer can be gradually reduced after the outer layer adsorbs the impurities, so that the problem that the waste gas is blocked from entering the internal channel of the adsorbent is solved, the adsorption effect of the adsorbent is lost, or the adsorption effect becomes worse, the inner part of the adsorbent still has the capacity of adsorbing the impurities, the utilization rate of the adsorbent is low, and the adsorption efficiency of the waste gas is poorer.
