具体实施方式 Detailed ways
下面结合附图，对本实用新型的具体实施方式进行说明。该种尾气处理装置包括依次相连接的对废气进行喷淋处理的喷淋装置3、对废气进行等离子吸附处理的等离子吸附装置4、用于收集废气的风机5和催化氧化装置6。在催化氧化装置6之后连接排气口8。在喷淋装置3之前还连接有光裂解箱1和活性炭吸附装置2。在光裂解箱1之前连接集气口7。其中，喷淋装置3通过喷淋将恶臭气体捕捉到液体中，附着于颗粒物质上的臭气分子通过湿法吸收氧化后被从空气中去除。等离子吸附装置4利用电子、离子、自由基和中性粒子小于分子，能够顺利进入分子内部，打开分子链，破坏分子结构的原理，以每秒钟300万至3000万速度的等量发射和回收，轰击发生臭气的分子，从而发生氧化等一系列复杂的化学反应，将有害物转化为无害物质。 Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described. The tail gas treatment device includes a spray device 3 for spraying waste gas, a plasma adsorption device 4 for plasma adsorption treatment of waste gas, a fan 5 for collecting waste gas, and a catalytic oxidation device 6 connected in sequence. An exhaust port 8 is connected after the catalytic oxidation device 6 . A photolysis box 1 and an activated carbon adsorption device 2 are also connected before the spray device 3 . Connect the gas collection port 7 before the photolysis box 1. Wherein, the spray device 3 traps the malodorous gas into the liquid by spraying, and the odor molecules attached to the particulate matter are removed from the air after being absorbed and oxidized by wet method. The plasma adsorption device 4 utilizes the principle that electrons, ions, free radicals and neutral particles are smaller than molecules and can smoothly enter the interior of molecules, open molecular chains, and destroy molecular structures, and emit and recover at the same rate of 3 million to 30 million per second , to bombard the molecules that generate the odor, so that a series of complex chemical reactions such as oxidation occur, and the harmful substances are converted into harmless substances. the
活性炭吸附装置2利用活性炭内部孔隙结构发达、有巨大比表面积的特点，来吸附（通过范德华力，即分子间作用力）恶臭气体分子。光裂解箱1利用特制高能光量子，裂解恶臭物质分子及空气中的氧分子，产生游离氧，即活性氧，其与氧分子结合，产生臭氧。通过高能光量子臭氧对恶臭气体进行协同光解氧化作用，使恶臭气体物质降解转化成低分子化合物、水和二氧化碳，再通过排风管道排出。 Activated carbon adsorption device 2 utilizes the characteristics of developed internal pore structure and huge specific surface area of activated carbon to adsorb (via van der Waals force, that is, intermolecular force) malodorous gas molecules. The photolysis box 1 utilizes special high-energy photons to crack odorous substance molecules and oxygen molecules in the air to generate free oxygen, that is, active oxygen, which combines with oxygen molecules to generate ozone. The high-energy light quantum ozone performs synergistic photolysis and oxidation on the malodorous gas to degrade the malodorous gas into low-molecular compounds, water and carbon dioxide, and then discharge it through the exhaust duct.
集气口7用于待排放的废气的收集，排气口8用于将处理后的气体对空排放。 The gas collection port 7 is used to collect the waste gas to be discharged, and the exhaust port 8 is used to discharge the treated gas to the air.
