Due to mankind's activity and economic fast development, China's environment is seriously damaged, and extreme climate showed increased causes serious threat to people's life and property, causes heavy losses to country, has hindered the sustainable development of national economy simultaneously.Country has also paid huge cost in order to administer environment.
The current discharged nitrous oxides total amount of China has exceeded 1,800 ten thousand tons, if do not take effective control measure, 5 years Chinese nitrogen oxide emissions of Future Ten will continue to increase, and may reach more than 3,000 ten thousand tons to the year two thousand twenty.China is coal-fired big country, and coal-burning power plant is the primary emission source of nitrogen oxide, accounts for 40% of total amount, will become the first batch of control object of country.
Honeycomb ceramics SCR denitrating catalyst Main Function is by the NO in discharging waste gas
xconvert nitrogen and steam to, to reach environmental emission standard.
SCR device is mainly made up of two large main bodys: remove agent preparation system and reactor body.By spray into reactant NH in reactor
3, NOx is reduced to nitrogen.Because this reduction reaction is comparatively responsive to temperature, therefore need add catalyst with intensified response activity, meet the temperature requirement of reaction.
Honeycomb fashion SCR denitrating catalyst main component generally comprises nano-TiO
2, V
2o
5and WO
3.These three kinds of shared catalyst ratios of composition exceed 95 ﹪, and TiO
2proportion is generally 80%～85%.In order to meet production technology needs, ensure easy extrusion modling, also needing in addition to increase the mixture additives such as some viscose glues and glass fibre increases pug intensity and mobility, adjusts its physical property.Due to these compositions stir mixing rear mobility and plasticity poor, moulding difficulty is larger.Again because the water holding capacity of product is poor, atmospheric crack very easily after moulding is therefore also higher to the production engineering specifications of dry kiln.During simultaneously due to this product calcining, can give off a large amount of NH
3, SO
3deng corrosive gas and compound hydrogen sulfate ammonia thereof, after calcining also easily because of cooling too fast cracking.
Therefore, this production requires also higher to calcining furnace.If the production technology assurance to this product is bad, may there is failed situation in dry kiln and calcining kiln.
