Description

An integrated VOCs adsorption concentration-catalytic oxidation degradation runner device and its process

technical field

The invention relates to an integrated VOCs adsorption concentration-catalytic oxidation degradation runner and a dual-function adsorption catalytic material thereof, belonging to the technical field of gas purification of organic gas adsorption concentration-catalytic oxidation degradation in industrial tail gas.

Background technique

Volatile organic compounds VOCs (Volatile Organic Compounds) are a class of organic compounds with high vapor pressure and easy to volatilize under normal temperature and pressure, such as benzene, toluene, xylene, methylene chloride, aldehydes, esters, alcohols, ketones, etc. ( [1] Wu Yongwen, Li Zhong, Xi Hongxia, Xu Kefeng, Han Jinglei, Guo Jianguang, VOCs Pollution Control Technology and Adsorption Catalytic Materials). VOCs are widely sourced from fine chemicals, petrochemicals, pharmaceuticals, electronic component manufacturing, printing, automobile exhaust, etc. It causes great harm to the environment, such as destroying the ozone layer, forming photochemical smog, causing smog, etc.; it also poses a great threat to human health, such as causing respiratory diseases and even carcinogenesis (Sun Tieyan, Zhou Qixing, Li Peijun, Pollution Ecology, Beijing: Science Press, 2001). Therefore, governments around the world attach great importance to the control of VOCs, and have promulgated increasingly stricter industrial exhaust emission standards. Therefore, it is imminent to develop effective VOCs treatment technology.

At present, for VOCs pollution control with medium and low concentrations (100-2000mg/m ³ ), there are mainly adsorption, catalytic combustion, photocatalytic degradation, plasma technology, direct combustion and so on. Among them, rotary adsorption is considered to be an economical and effective treatment technology, and it has also been applied to the treatment of industrial tail gas VOCs. Rotary wheel adsorption is a gas purification technology that can continuously adsorb and desorb. It mainly adsorbs VOCs in the gas through the adsorption area of the rotor, so as to achieve the goal of gas purification; at the same time, enrich the VOCs in the adsorption area. The VOCs in the desorption area are continuously transferred to the desorption area, desorbed and desorbed by the hot air purged in reverse, the adsorbent in the desorption area can be regenerated and then continuously transferred to the adsorption area for adsorption operation; while the VOCs desorbed from the desorption area are desorbed. collected for centralized processing.

However, there are certain bottlenecks in the current VOCs runner technology, mainly including: (1) After the VOCs are enriched and desorbed by the runner, a follow-up treatment device is still required, such as a catalytic combustion destruction device for complete degradation, etc., and the structure is not compact. Both energy consumption and cost are high; (2) the existing VOCs adsorption-regeneration runner is not easy to completely remove VOCs during the regeneration process, resulting in a continuous decline in the adsorption efficiency of the runner when it is recycled, thus requiring intermittent shutdowns. VOCs that are not easily desorbed on the rotor are further processed.

The structure of the VOCs adsorption concentration-catalytic oxidation degradation runner of the present invention is simple, combined with Figure 1, its working principle is:

1. The organic waste gas is brought into the rotor adsorption zone 1 by the pump, and the VOCs in the exhaust gas are adsorbed by the adsorption sites on the surface of the adsorption catalyst material in the rotor adsorption zone 1, thereby being purified, and the purified air is sent out through the blower 3. With the increase of adsorbed VOCs, the adsorption zone 1 of the rotor gradually tends to a saturated state. In order to maintain its stable performance of adsorption and removal of VOCs, it is necessary to regenerate the adsorption catalyst in the runner. At this time, the runner that tends to be saturated is driven by the motor 6 and slowly turns into the regeneration area to start the regeneration process. .

2. After the air is heated by the heater 4, it is blown forward into the catalytic oxidation zone 2 of the rotor. At high temperature, the VOCs concentrated on the rotor are catalyzed and oxidized by the catalytic sites on the surface of the adsorbed catalyst to generate CO ₂ and water, which are blown by the fan. 5 guide and discharge; at the same time, the dual-function adsorption catalyst on the rotor catalytic oxidation zone 2 is regenerated, and the adsorption capacity is restored, and it is turned back to the rotor adsorption zone 1 for recycling under the drive of the motor 6 .

Compared with the existing VOCs adsorption-regeneration runner technology, the present invention has the following advantages and effects:

1. Compact structure, energy consumption and cost will be reduced: the existing VOCs adsorption-regeneration runner can only realize the concentration of VOCs in the exhaust gas, and the concentrated VOCs still needs to be post-treated in the future, such as adding a catalytic combustion reactor; and the present invention The integrated VOCs adsorption concentration-catalytic oxidation degradation runner can achieve continuous purification of VOCs in industrial tail gas only through the runner under the adsorption-regeneration cycle operation, without subsequent reprocessing;

2. Continuous cycle performance is stable: the existing VOCs adsorption-regeneration runner regeneration process is not easy to completely remove VOCs, resulting in a continuous decline in adsorption efficiency when the runner is recycled; and the integrated VOCs adsorption concentration-catalytic oxidation degradation conversion of the present invention During the wheel regeneration process, VOCs will be completely converted into CO ₂ and water, which is easy to desorb, thus ensuring the performance stability of the continuous cycle use of the wheel and meeting the national emission standards for industrial tail gas.
