Embodiment Construction

[0018] Specific embodiments of the present invention will be described in detail below in conjunction with technical solutions and accompanying drawings.

[0019] The imported gas distribution method of the dielectric barrier discharge activated carbon regeneration reactor is to place the PVC material air guide pipe in the activated carbon packed bed of the dielectric barrier reactor to provide the reaction gas source for the reactor. The length, width and height of the activated carbon packed bed are 400mm ×400mm×16mm insulating plastic, activated carbon filled bed. The arrangement of the air duct is as follows figure 1 As shown in the prickly shape, the diameter of the air guide tube is 5mm, and there are gas outlet micropores all over the body, and the diameter of the micropores is 0.5mm; the gas enters from the inlet through the air pump, and seeps out from each micropore along the air guide tube, uniformly Distributed in the discharge space of the reactor, it provides th...

Abstract

The invention discloses a lead-in type gas distribution method for a dielectric barrier discharge activated carbon regeneration reactor, belonging to the technical field of environmental pollution control and chemical industrial adsorbent regeneration. The lead-in type gas distribution method is characterized in that a gas-guide tube is put into the activated carbon packed bed of the dielectric barrier reactor, wherein gas outlet micropores are distributed on the gas-guide tube; and fed gas enters the activated carbon bed layer via the micropores on the gas-guide tube and is evenly distributed in the discharge space of the reactor for providing a reaction gas source for the reactor for discharging. For electrode systems with rectangular metal electrodes and media, the gas-guide tube can be made into a Z shape and a barb shape; and for electrode systems with round metal electrodes and media, the gas-guide tube can be spiral. The gas distribution method disclosed by the invention has a simple structure, the gas-guide tube is convenient to install and manufacture, a stable and evenly-distributed gas source can be provided for the dielectric barrier discharge zone, the gas use ratio is improved, and the gas distribution method is suitable for gas distribution for the amplifying device of the dielectric barrier discharge activated carbon regeneration reactor.

Description

technical field [0001] The invention belongs to the technical field of environmental pollution control and regeneration of chemical adsorbents, and relates to a lead-in gas distribution method for a dielectric barrier discharge activated carbon regeneration reactor. Background technique [0002] Activated carbon has a very developed internal pore structure and a large specific surface area, strong adsorption capacity, and its source is relatively easy to obtain, and the cost is relatively low. It is one of the most commonly used adsorbents and is widely used in environmental protection, chemistry, food, etc. and many other fields. However, as the application range of activated carbon is becoming wider and wider, the consumption is also increasing rapidly. The amount of waste activated carbon generated in the application process is large and the area is large. If it is not recycled, activated and reused, it will not only cause a waste of resources, but also It will cause sec...
