熱氧化技術

沸石轉輪濃縮技術Zeolite Rotor Concentration Principle

工藝原理 / Process Characteristics ◆ VOC 濃縮裝置可以非常有效的凈化和濃縮含有 VOCs 的氣體，通過和氧化裝置或者回收裝置組合可以極大降低 VOC的處置成本。尤其對于大風量，低濃度的氣體。
◆ VOC 濃縮轉輪使用各種疏水性分子大量浸制到蜂窩陶瓷中，再經過高溫焙燒生成。濃縮轉輪被密封分為：處理區，再生區以及冷卻區三個區域。整個轉輪由一個齒輪馬達驅動。
◆ 含有 VOC 的被處理空氣（通常需要前置過濾）被送到濃縮裝輪處理區，在處理區 VOC 被吸附后，經過凈化的氣體從處理區排入煙囪。
◆ 轉輪的脫附區鄰近處理區。濃縮的 VOC可以用少量的高溫脫附風脫附出來，從而達到濃縮的效果（濃縮倍率：5-20 倍），然后進入后處理裝置。
◆ 脫附后的轉輪進入冷卻區進行冷卻。冷卻風可以是一小部分待處理的含 VOC的氣體，這部分氣體可以進入換熱器或者加熱器加熱成為脫附風。

The desorbed part of the rotor is further rotated to the cooling zone, where the zone is cooled by the cooling gas. A part of VOC laden exhaust gas from the factory passes through the cooling zone and is
transferred to a heat exchanger or a heater to be heated and utilized as desorption air.

VOC concentration rotor is made of honeycomb inorganic paper as a substrate, in which the High-Silica zeolite (Molecular Sieve) is impregnated. The rotor is divided into 3 zones such as process, desorption and
cooling zones by the casing structure and heat resistance air sealing. The rotor is constantly rotated at the optimum rotation speed by a geared motor.

VOC laden exhaust gas passes through the process zone of the rotor being continuously rotated, and the incombustible zeolite in the rotor adsorbs VOCs and exhausts purified gas to the ambient.
VOC adsorbed part of the rotor is rotated to the desorption zone, where the adsorbed VOCs can be desorbed with small amount of high temperature desorption air and be concentrated to the high concentration
level (5 to 20 times). Then, the high concentrated VOC gas is transferred to appropriate post treatment systems such as incinerators or recovery systems.

The desorbed part of the rotor is further rotated to the cooling zone, where the zone is cooled by the cooling gas. A part of VOC laden exhaust gas from the factory passes through the cooling zone and is transferred
to a heat exchanger or a heater to be heated and utilized as desorption air.

技術優勢 / Process Characteristics

高效能 ? 高效率 / High performance & efficiency 將吸附性能極好的疏水性分子篩作為吸附劑使用，對于廣泛的 VOC 種類，不同的運轉條件，都可以提供卓越的性能 Using High silica zeolites with enormous adsorption capacity allows our VOC concentrator to flexibly treat various kinds of VOCs and work under different conditions of operation.

高沸點的溶劑處理 / Capability of treating VOCs with high boiling point 用活性炭時因為有再生溫度的限制而無法處理高沸點的 VOC, 對于使用疏水性的分之篩時，可以利用其不燃性。高耐熱性的特點可以在高溫條件下再生，從而得以處理 Carbon material has a difficulty to treat VOCs with high boiling point due to its desorption temperature limit. In contrast, the characteristics of our zeolite rotors are incombustible and high heat resistance, which enables
our VOC concentrator to use the adsorption air with high temperature.

惰性 / Inertness 即使是苯乙烯和環己酮等具有熱聚性高的 VOC, 也能使用疏水性的分子篩高效處理 VOC easily polymerized by heat energy (e.g. st yrene, cyclohexanone, etc) can be effectively treated by High-Silica zeolite.

清洗和活化 / Cleanability & activation by special heat treatment 心臟部分的濃縮裝輪因為在高溫下燒結處理而成，完全是無機的結合體。如果發生蜂窩堵塞，可以進行水洗。另外，分子篩轉輪可以根據實際情況通過高溫活化 Our zeolite rotors through calcining process have come to all inorganic material including the adhesive. Clogging in the rotor element might occur after a certain period of use. But, don’t worry!!
The rotor is washable in a proper manner to remove accumulated dust. It’s even better that our zeolite rotor can be reactivated by heat treatment according to circumstances.

Recovery of solvent type

工藝原理 / Process Characteristics

有機廢氣經蓄熱體或換熱器加熱后，在催化劑的作用下燃燒，氧化分解為CO2和H2O。反應后的高溫氣體經熱量回收用于預熱后續的有機廢氣后直接排放，
或者直接返回生產環節進一步利用熱能。每個蓄熱室依次經歷蓄熱-放熱-清掃等程序，連續工作。設備運行溫度300℃左右。 Organic exhaust gas heated by the regenerator or heat exchanger, under the action of the catalyst combustion, is oxidized into decomposition of CO2 and H2O.
The high-temperature gas is directly released after heat recovery for preheating the subsequent organic gas, or directly returns to the production process for further use of heat. Each
of the regenerators is subjected to heat storage, heat dissipation, and cleaning procedures in turn. Equipment operating temperature is about 300 ℃.
