Description
Technical field
This utility model belongs to catalyst regeneration techniques field, is specifically related to the automatic cleaning and regeneration line of fixed SCR denitration.
Background technology
Nitrogen oxides is one of coal-burning power plant's primary discharge pollutant, is the main matter forming acid rain and photochemical fog. Coal-fired plant flue gas denitration engineering adopts V2O5-TiO2-W/MO catalyst series mostly. Catalyst body is vesicular texture, load that active component (mainly includes this series of metal oxide of V2O5-TiO2-W/MO) is in hole wall pore structure, general with the position that it is suitable that many stratiforms are placed in flue, the flue gas being mixed with reducing gas ammonia passes through generation flue gas nitrogen oxide reduction reaction during catalyst duct, with this purpose reaching to reduce or remove nitrogen oxides. The activity of catalyst increased and the degeneration that decays gradually with the operation time, causes that the reason that catalyst activity is decayed has physical factor, also has chemical factor. In physical factor, it is most commonly that flying dust and ammonium salt sedimentation covers, more seriously thermal sintering, because the catalyst after thermal sintering is non-renewable, these factors directly result in the surface-coated lid of catalyst activity, even duct blocking, hinders flue gas and active ingredient contacts, finally results in denitration efficiency and declines. In chemical factor, the harmful substance such as arsenic and alkali metal directly destroys react with active component generation, causes that catalyst poisoning is corroded, finally results in catalysis activity decrease, when production requirement can not be met, disposal need to be scrapped and change raw catelyst or consider catalyst regeneration recycling.
Raw catelyst is expensive, and every cubic metre of marked price, up to 3-4 ten thousand yuan, the coal unit of 600 megawatts, it is necessary to the catalyst of about 600 cubic metres, accounts for about the 40% of whole denitration construction costs. In addition, the service life of catalyst is shorter, within general about 3 years, it is accomplished by changing, one 600,000 kilowatts of unit changes catalyst costs every year up to 10,000,000 yuan, SCR dead catalyst is because containing the heavy metal assembled in the toxic metals such as V2O5, WO3 and use procedure, polluting transfer to the improper meeting of method of disposal of decaying catalyst, for solving this problem, the method taked is that catalyst is regenerated, to improve resource reason utilization ratio to greatest extent.
Existing SCR catalyst regeneration device is the reactor assembly that can realize denitration reaction with regeneration. This SCR catalyst denitration reaction and SCR catalyst regeneration can carry out at interval in same reaction unit. Wherein the structure of regenerative process is arranged on denitration main structure body. Although said apparatus avoids the movement to catalyst module but needs often overlapping construction catalyst regeneration system on flue gas denitrification system. And SCR catalyst 2-3 just needs regeneration once so that the utilization rate of catalyst on-line regeneration facility lowly builds, safeguard and operating cost is huge, and economic benefit is extremely low.
