沸石转轮浓缩技术zeolite rotor concentration principle

工艺原理 / process characteristics◆ voc 浓缩装置可以非常有效的净化和浓缩含有 vocs 的气体，通过和氧化装置或者回收装置组合可以极大降低 voc的处置成本。尤其对于大风量，低浓度的气体。
◆ voc 浓缩转轮使用各种疏水性分子大量浸制到蜂窝陶瓷中，再经过高温焙烧生成。浓缩转轮被密封分为：处理区，再生区以及冷却区三个区域 。整个转轮由一个齿轮马达驱动。
◆ 含有 voc 的被处理空气（通常需要前置过滤）被送到浓缩装轮处理区，在处理区 voc 被吸附后，经过净化的气体从处理区排入烟囱。
◆ 转轮的脱附区邻近处理区。浓缩的 voc可以用少量的高温脱附风脱附出来，从而达到浓缩的效果（浓缩倍率：5-20 倍），然后进入后处理装置。
◆ 脱附后的转轮进入冷却区进行冷却。冷却风可以是一小部分待处理的含 voc的气体，这部分气体可以进入换热器或者加热器加热成为脱附风。

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.

技术优势 / process characteristics

高效能 • 高效率 / high performance & efficiency将吸附性能极好的疏水性分子筛作为吸附剂使用，对于广泛的 voc 种类，不同的运转条件，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.

高沸点的溶剂处理 / capability of treating vocs with high boiling point用活性炭时因为有再生温度的限制而无法处理高沸点的 voc, 对于使用疏水性的分之筛时，可以利用其不燃性。高耐热性的特点可以在高温条件下再生，从而得以处理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即使是苯乙烯和环己酮等具有热聚性高的 voc, 也能使用疏水性的分子筛高效处理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心脏部分的浓缩装轮因为在高温下烧结处理而成，完全是无机的结合体。如果发生蜂窝堵塞，可以进行水洗。另外，分子筛转轮可以根据实际情况通过高温活化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.
