The present invention realizes by the following technical solutions: a kind of ozone-type thermal-flame device cooperation-removal various pollutants in fume system, air is after oxygenerator, nitrogen is collected storage and is done other purposes, and oxygen forms ozone after entering ozone generator, pure oxygen mist, and fully mix in gas mixture with upstream flue gas, then together send into burner premix with fuel (oil/gas) and enter efficient burning in burner, the uniform oxygen-enriched combusting in formation temperature field, formation temperature is high, the oxygen-enriched combusting of uniform temperature fields, obtain ozone-type high-temp combustion flame atmosphere, the thermal-flame of the strong oxidizing property and oxygen-enriched combusting generation that make full use of ozone activity molecule carries out fully oxidized to various pollutants in fume, decompose, the new flue gas produced thoroughly removes pollutant through alkaline absorbent device for smoke pollutants.
When native system runs, air produces oxygen and then enters the mist that ozone generator forms ozone and oxygen after oxygenerator, mixes in gas mixer with the flue gas of Residual contamination thing, eventually passes burner and enters burner realize O together with fuel
2/ CO
2efficient burning under atmosphere, obtain the homogeneous temperature field of 1500 DEG C ~ 2000 DEG C, in burner hearth combustion process, make full use of the strong oxidizing property of ozone activity molecule and the acting in conjunction of high temperature, the pollutant carried flue gas is oxidized, decomposes, SO in flue gas
2, NO, Hg be oxidized to high-valence state, finally by alkaline solution absorption, Er bioxin and the oxidized decomposition of VOCs, thoroughly remove pollutant in flue gas, and realize CO
2enrichment, is beneficial to follow-up CO
2catch.
The key of this system is tissue reasonably burning, in half-life of ozone, coordinates ozone strong oxidizing to the contradiction between the oxidation of NO and high temperature NO generation.
Further, the heat that burner produces is used for heat supply or generating, and this system can as the core component of new distributed energy resource system.
The present invention is mainly little for exhaust gas volumn, the cooperation-removal technology of the flue gas system that pollutant levels are high, kind is many, completely different from other flue gas pollutant Treatment process in principle and structure, mainly utilize the strong oxidizing property of ozone activity molecule and the thermal-flame acting in conjunction of oxygen-enriched combusting to pollutant oxidation, decompose, then absorbing and removing, the heat that efficient burning produces is used for generating or heat supply, can effectively solve type smoke pollutant removal problem, reach ultra-clean discharge standard, and it is simple to have technique, the plurality of advantages such as reliability is high, practical.
