Problems solved by technology

When the concentration of organic pollutants decreases, it is difficult to maintain the temperature required for combustion in the regenerative combustion chamber; when the concentration of organic pollutants is high, it is easy to cause problems such as excessive temperature and catalyst failure, making it difficult to maintain combustion
Therefore, when the concentration of organic waste gas is low, combustion is more difficult. If heat is not input to the combustion system, the requirements for processing low-concentration organic waste gas cannot be met.
Although plasma technology can treat organic waste gas with extremely low concentration, there are many problems such as high energy consumption and insufficient degradation when the concentration of organic pollutants is high.

Abstract

The invention relates to a device for combusting and treating organic waste gas through a plasma enhanced porous medium. The device comprises a filter, a reactor, a high-voltage power supply and a controller, wherein the filter is used for removing particulate matters in the organic waste gas; the reactor is used for performing thermal oxidization and plasma oxidization to degrade the organic waste gas; the high-voltage power supply is used for providing plasma; the controller is used for controlling flow and temperature of the reactor; the filter is connected with the reactor; and the reactor is connected with the controller and the high-voltage power supply respectively. According to the device, the organic waste gas is degraded due to synergism of heat storage effect of porous medium material and oxidation effect of plasma free radicals, so that the degradation efficiency of the organic waste gas is improved; and meanwhile, input energy of the plasma is adjusted according to concentration of the organic waste gas, so that the degradation efficiency of the organic waste gas is ensured and the input energy consumption is effectively reduced. The device has the advantages of wide application range of the concentration of the organic waste gas, low input energy, high processing efficiency and high controllability of system; and the device can be widely used for processing the organic waste gas released in production of various industries such as pharmacy, coating industry and the like.

Description

Technical field [0001] The invention belongs to the field of environmental pollution control, and specifically relates to a device and method for treating organic waste gas by using discharge plasma to intensify combustion and combining with porous medium combustion. Background technique [0002] Organic waste gas refers to harmful gases containing organic compounds such as hydrocarbons, alcohols, ketones, acids and amines produced in the process of energy extraction and industrial production, such as methane (CH 4 ), volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), etc. The composition of organic waste gas is complex. Some are important sources of the greenhouse effect, some are important precursors for the formation of photochemical smog and PM2.5, and some are even strongly carcinogenic, mutagenic and teratogenic. CH 4 The greenhouse effect caused by CO 2 21 times that of my country’s annual emissions of CH from coal mining 4 The total amount of gas ...
