Example Embodiment

[0021] Such as figure 1 As shown, a device for treating malodorous gases and industrial VCDs includes a cylindrical insulating housing 1 with an inner diameter of 50 mm and a length of 200 mm. The insulating housing 1 is made of polymethyl methacrylate, and both ends are closed. An air inlet 6 and an air outlet 7 are respectively provided at both ends of the surface. An electrode 5 made of sintered metal (Northwest Nonferrous Metal Research Institute) is arranged at the central axis of the cavity of the insulating housing, and the effective diameter is 0.5 mm. The electrode has a 3D mesh porous structure. Different pore size layers form a pore size gradient. The pore size is mainly mesopores (2-50nm) and macropores (>50nm). There are a large number of connected or semi-connected pores inside, with a porosity of 80 ~90%, the electrode 5 is loaded with a transition metal catalyst, and one or more of Mn, Cu, Fe, Pb, V, Ni, Co and Ti can be selected.

[0022] There is a high-voltage...

Abstract

The invention discloses a device and a method for treating obnoxious gas and industrial volatile organic compounds (VOCs). The device comprises a cylindrical insulation shell with an air inlet and an air outlet, an electrode connected with a high-voltage pulse power supply is arranged in the cavity of the insulation shell, and an adsorption layer which encircles the electrode and is made of active carbon fibers and a metal sheet which is grounded are sequentially attached to the inner wall of the insulation shell from inside to outside. By the invention, plasma reaction and active carbon fiber adsorption technology are combined, so that the retention time of the obnoxious gas or the industrial VOCs in the device is prolonged, and the treatment efficiency is improved; and in addition, active carbon fiber adsorption and regeneration are performed at the same time, so the service life of the active carbon fibers is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a device and method for controlling malodorous gas and industrial VOCs. Background technique [0002] At present, the ever-increasing discharge of toxic and harmful exhaust gas seriously interferes with the daily life of residents, deteriorates people's living environment, and further causes harm to human health and the ecological environment. Odorous industrial VOCs (volatile organic compounds) and stench have especially become the focus of residents' complaints. Many provinces and cities in China have launched the "Clean Air Action", so it is urgent to find a feasible and affordable technology to control VOCs and odor emitted by industry. [0003] Biological methods and activated carbon adsorption are currently the most common processes for controlling industrial VOCs and odors. The biological method has the advantages of low investment and operating costs, b...
