        2. 沸石分子篩轉輪吸附濃縮的廢氣處理介紹

          沸石分子篩轉輪組合為一中心軸承與轉體,是吸附、脫附及濃縮焚化三項操作單元格為一體,且比較完善的設備之一,相對比蜂窩狀的活性炭具有非常多的優勢,兩者在吸附工藝上是相同的,但沸石的吸咐性能遠大于活性炭,如甲醛的去除,活性炭吸附基本使用周期小于一年,很容易吸附飽和定期需要更換,沸石轉輪分子篩使用年限可以達到10年以上,在資金和更換頻率上大大降低,可降低人力物力的支出,安全性、連續性效率等一次性投資收益幾十年,而且脫附后和催化燃燒階段的有機VOC氣體濃度和效率更高。所以沸石分子篩轉輪被越來越多的應用到處理有機廢氣當中。
          The combination of zeolite molecular sieve wheels is a central bearing and a rotating body, which is one of the relatively complete equipment for adsorption, desorption, and concentration incineration. It has many advantages over honeycomb activated carbon in terms of adsorption process, but the adsorption performance of zeolite is much greater than that of activated carbon, such as the removal of formaldehyde. The basic service life of activated carbon adsorption is less than one year, It is easy to adsorb and saturate, and it needs to be replaced regularly. The service life of zeolite rotary molecular sieve can reach more than 10 years, greatly reducing the cost and frequency of replacement, and reducing the expenditure on manpower and material resources. The one-time investment returns such as safety and continuity efficiency can last for decades. Moreover, the organic VOC gas concentration and efficiency in the desorption and catalytic combustion stages are higher. So zeolite molecular sieve wheels are increasingly being used in the treatment of organic waste gas.
          沸石分子篩的工藝原理運行方式:
          The process principle and operation mode of zeolite molecular sieve:
          沸石分子篩吸附濃縮轉輪密封系統分為處理區,再生區和冷卻區三個部分,轉輪緩慢旋轉(1~6r/h)使各個區內吸附過程完整連續運轉。當VOCs有機廢氣通過前置處理區時,其中的有機廢氣成分被轉輪中的吸附劑所吸附去除,廢氣被凈化后的空氣從濃縮轉輪的處理區間而排空,轉輪逐漸達到吸附飽和。同時在再生區高溫下空氣通過吸附飽和,廢氣被吸附脫附后由經高溫空氣排走,達到連續去除VOCs效果的同時也恢復轉輪的吸附能力提高廢氣濃度,脫附的高溫氣體進入RTO/CO氧化裝置便于進行氧化處理。
          The sealing system of the zeolite molecular sieve adsorption and concentration rotary wheel is divided into three parts: the treatment zone, the regeneration zone, and the cooling zone. The rotary wheel slowly rotates (1-6r/h) to ensure the complete and continuous operation of the adsorption process in each zone. When VOCs organic waste gas passes through the pre-treatment zone, the organic waste gas components are adsorbed and removed by the adsorbent in the runner. The purified air in the waste gas is discharged from the treatment zone of the concentration runner, and the runner gradually reaches adsorption saturation. At the same time, at high temperatures in the regeneration zone, the air is saturated through adsorption, and the waste gas is adsorbed and desorbed before being discharged through high-temperature air, achieving continuous removal of VOCs while also restoring the adsorption capacity of the runner to improve the concentration of waste gas. The desorbed high-temperature gas enters the RTO/CO oxidation device for easy oxygenation treatment.
