Description
Technical Field
The utility model relates to the technical field of waste treatment, in particular to an adsorption tower convenient for controlling the temperature of an adsorption bed.
Background
The volatilization of the organic solvent can be caused in the storage, transportation and use processes of the organic material, so that VOCs are formed, and the environment is controlled and polluted. Especially in the places such as pharmacy, fine chemical industry, petrifaction, gas station, tank farm, etc., the pollution is more serious.
At present, the VOCs treatment process is relatively more, but the treatment processes which can be selected to be used are different due to the influence of comprehensive factors such as investment cost, running cost, current production situation and the like, wherein the adsorption process is one of the most commonly used treatment processes. The adsorption process comprises an adsorption discarding method, an adsorption-hot air desorption-catalytic combustion method, an adsorption-steam desorption-condensation method and the like, and the key steps of the adsorption process are the adsorption process of VOCs.
Many factors influence the adsorption effect, such as adsorbent properties, adsorption column parameters (superficial velocity, adsorbent bed thickness, etc.), exhaust gas characteristics, temperature, etc. In engineering, the too high temperature of the adsorption bed not only can affect the adsorption efficiency, but also can cause safety accidents, and the temperature of the waste gas in summer can exceed 35 ℃, so that the adsorption efficiency can be obviously reduced when the temperature exceeds 30 ℃ for low-boiling-point substances such as dichloromethane, diethyl ether and the like. There are many reasons for the temperature rise of the adsorbent bed during the adsorption process, such as environmental factors (sun exposure), heat released during the adsorption process, abnormal overtemperature of the intake air, etc. According to the specifications, the temperature of the adsorbent bed should not exceed 45 ℃, and if the temperature exceeds the temperature, the adsorption capacity of the adsorbent is drastically reduced; when the temperature of the adsorbent bed exceeds 73 ℃, safety accidents (such as spontaneous combustion of the adsorbent bed) may occur. The spontaneous combustion accident of the current active carbon adsorption tower frequently happens, so that the accurate control of the temperature of the adsorption bed has great significance on the safety and adsorption efficiency of the adsorption process.
However, it is currently common practice to shut down the adsorption column and switch the off-gas to a bypass when the temperature exceeds 45 c, and to re-activate the column when the temperature drops below 45 c, and so on and off. However, this temperature control method obviously causes direct discharge of the polluted gas, resulting in poor treatment effect of the polluted gas.
