Description
Technical Field
The invention belongs to the technical field of flue gas denitration, and particularly relates to flue gas denitration equipment for an industrial silicon ore heating furnace.
Background
At present, no mature denitration technology exists in the flue gas of the industrial silicon ore heating furnace in China, and due to the specific flue gas characteristics of the industrial silicon ore heating furnace, the mature denitration technologies (such as a selective non-catalytic reduction (SNCR) process and a Selective Catalytic Reduction (SCR) process) applied to a general thermal power boiler and an industrial boiler cannot be directly transferred to the flue gas denitration of the industrial silicon ore heating furnace. The main reasons are: firstly, the flue gas temperature of the industrial silicon ore heating furnace is low, the industrial silicon ore heating furnace is extremely unstable, the variation range is large, and no stable reaction temperature interval suitable for conventional SNCR and SCR denitration processes exists, wherein the reaction temperature interval required by the SCR denitration process is 300-400 ℃, and the reaction temperature interval required by the SNCR denitration process is higher than 800 ℃. The temperature of the flue gas at the outlet of the industrial silicon ore heating furnace frequently changes with the amount of the materials in the furnace and the reaction process of the materials, and reaches 400 ℃ at low temperature and more than 1000 ℃ at high temperature. A waste heat boiler is arranged behind the latest industrial silicon ore heat furnace, a multi-layer heat exchanger is arranged in the waste heat boiler, the heat exchanger comprises an evaporator and an economizer so as to recover the heat of flue gas, the waste heat boiler can be used for power generation or other industries or civilian use, the flue gas discharged from the waste heat boiler is discharged after dedusting and desulfurization, and the temperature of the flue gas at the outlet of the waste heat boiler is lower than 150 ℃. The prior environmental protection requirements do not require the denitration of the flue gas of the industrial silicon ore heating furnace, but the environmental protection requirements are continuously improved in recent years, and various places put forward the denitration requirements of the flue gas. From the above analysis, it can be known that the flue gas temperature in the exhaust-heat boiler is mostly lower than 800 ℃ required by the SNCR denitration process, so that when the SNCR denitration process is adopted, the denitration efficiency is extremely unstable, the denitration reducing agent (urea or ammonia water) sprayed into the flue gas does not react to perform denitration, and can generate secondary pollution along with the discharge of the flue gas, and the damage is caused to the subsequent furnace and the subsequent rotary furnace. The temperature of the flue gas after the waste heat boiler is lower than 300-400 ℃ required by the SCR denitration process, and the conventional SCR denitration process is not suitable for flue gas denitration. If the existing low-temperature denitration catalyst which is not mature at present is adopted, firstly, the catalyst is huge in required quantity, and secondly, the catalyst is extremely high in price, so that the investment of the whole project is extremely remarkable, and the catalyst is difficult to accept by a company. If chemical oxidation denitration is carried out after cloth bag dust removal, the problems of low denitration effect, unstable standard discharge and extremely high operation cost exist, wherein the strong oxidant oxidizes the NOx and oxidizes Sox and other reducing substances in the flue gas, so that the oxidant is very high in consumption, the operation cost is extremely high, and the strong oxidant is unacceptable for a company; meanwhile, secondary pollution is easy to generate, so the method is not approved and popularized by environmental protection departments.
