The current discharged nitrous oxides total amount of China surpasses 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 to the year two thousand twenty, may reach more than 3,000 ten thousand tons.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 comprised 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 active with intensified response, 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 surpass 95 ﹪, and TiO
2proportion is generally 80%～85%.In order to meet production technology needs, guarantee 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
