Zeolite molecular sieve regeneration device and regeneration method

Abstract

The invention discloses a zeolite molecular sieve regeneration device and a regeneration method, and belongs to the technical field of zeolite molecular sieves. The regeneration device comprises a microwave digestion tank, a microwave generator and a temperature controller; the microwave generator is arranged at an opening of the microwave digestion tank; the temperature controller is used for controlling the heating temperature of a zeolite molecular sieve; and a weighing device is used to weigh the heated zeolite molecular sieve. The regeneration method comprises the following steps: placinga saturated zeolite molecular sieve which adsorbs volatile organic compounds (VOCs) into the microwave digestion tank, starting the temperature controller and setting a temperature, starting the microwave generator, heating the zeolite molecular sieve, recording the time, turning off the microwave generator every one minute, taking out the zeolite molecular sieve for weighing, and repeating the heating and weighing processes until the weight of the zeolite molecular sieve does not change any more, so that regeneration is completed. According to the invention, microwave is utilized to rapidlyheat the zeolite molecular sieve, and the regeneration temperature is lower than the regeneration temperature of a conventional regeneration method, so that the regeneration method has the advantagesof high desorption rate, low energy consumption and the like. In addition, the desorbed substances after microwave desorption are directly condensed into a liquid state and thus are convenient to recycle, so that secondary pollution is avoided.

Description

technical field [0001] The invention belongs to the technical field of zeolite molecular sieves, in particular to a zeolite molecular sieve regeneration device and regeneration method. Background technique [0002] With the development of my country's economy and the improvement of chemical industry level, the use of organic solvents in petroleum, chemical, metallurgy, pharmaceutical and other industries has also increased rapidly. In addition, organic waste gases (VOCs) will also be produced in daily life activities such as home decoration and garbage transportation. ). VOCs are highly volatile and toxic, and are easy to diffuse in the air. They have a strong irritating effect on human eyes and nose, and have great damage to the heart, lungs and other internal organs and nervous system. Mild symptoms manifest as headaches. ,tired. Severe cases manifest as dyspnea, nerve paralysis, cancer, and even death, seriously endangering human health. Among the many methods for treat...
