Description
Technical field
The present invention relates to boiler plant technical field, a kind of multiple waste liquid waste gas fuels and boiler plant of denitrification integral of burning.
Background technology
At present for some large-scale chemical enterprises, complexity and the multiformity of chemical products due to its production process, cause producing multiple waste liquid and waste gas in process of production, as: expoxy propane waste gas and waste liquid, expoxy propane storage tank aerofluxus, dehydrogenating propane device waste gas, torch reclaims gas, polyethers device waste gas, nearly ten kinds of compositions such as dehydrogenating propane device PSA tail gas, the waste liquid waste gas that calorific value is different with state, these waste liquid waste gas there are pollutant even noxious substance, can not directly discharge, wasted energy boiler need to be used to be burnt, turn waste into wealth, produce steam for Chemical Manufacture, simultaneously because the raising of Environmental Protection in China standard, this boiler combustion and produce NOx emission concentration requirement and be not higher than 100
Mg/Nm3, existing boiler cannot meet above-mentioned requirements.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of multiple waste liquid waste gas fuels and boiler plant of denitrification integral of burning, it is capable of realizing exhaust gas denitration while liquids and gases burn the most completely, is substantially reduced NOx emission concentration.
Its technical scheme is such that a kind of multiple waste liquid waste gas fuels and boiler plant of denitrification integral of burning, it is characterized in that, it includes burner hearth, described burner hearth sequentially connects downward-flow flue, denitration uptake flue and exhaust pass, described burner hearth sidepiece is provided with waste liquid waste gas mixing burner, gas-liquid synchronousing combustion in described waste liquid waste gas mixing burner, between described burner hearth and described downward-flow flue, superheater is installed, higher level's economizer is installed in described downward-flow flue, in described denitration uptake flue, ammonia-gas spraying device is installed, described exhaust pass is respectively arranged with SCR reactor from top to bottom, subordinate's economizer, air preheater and exhanst gas outlet, it is disposed with two-layer catalyst in described SCR reactor.
It is further characterized by, and described burner hearth sidepiece is disposed with four described waste liquid waste gas mixing burners；
Described ammonia-gas spraying device injection ammonia and hot-air mixed gas；
Every layer of described catalyst includes four catalyst blocks being arranged side by side.
After using the equipment of the present invention, by waste liquid waste gas mixing burner, gas-liquid synchronousing combustion makes the liquids and gases diverse fuel of both forms all can burn the most completely, denitration uptake flue and the layout of SCR reactor, by the nitrogen oxides (NOx) in catalyst reduction flue gas, generate harmless nitrogen and water, thus NOx emission concentration is reduced to 100
Below mg/Nm3, greatly reduces NOx emission concentration；Burner hearth sidepiece is disposed with four waste liquid waste gas mixing burners and makes gas-liquid burning more abundant, and the setting of four catalyst blocks makes denitration reduction reaction preferably carry out.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
nullAs shown in Figure 1，A kind of multiple waste liquid waste gas fuels and boiler plant of denitrification integral of burning，It includes burner hearth 1，Burner hearth 1 sequentially connects downward-flow flue 11、Denitration uptake flue 5 and exhaust pass 12，Burner hearth 1 sidepiece is provided with four waste liquid waste gas mixing burners 2，Gas-liquid synchronousing combustion in waste liquid waste gas mixing burner 2，Superheater 3 is installed between burner hearth 1 and downward-flow flue 11，Higher level's economizer 4 is installed in downward-flow flue 11，Ammonia-gas spraying device 6 is installed in denitration uptake flue 5，Ammonia-gas spraying device 6 sprays ammonia and hot-air mixed gas，Owing to ammonia transport preserves inconvenience，The general water formation ammonia that is dissolved in by ammonia carries out transport preservation，It is passed through hot-air to carry out heating make Ammonia valatilization out be mixed with hot-air ejection when needs injection ammonia，Exhaust pass 12 is respectively arranged with SCR reactor 7 from top to bottom、Subordinate's economizer 9、Air preheater 10 and exhanst gas outlet 13，Two-layer catalyst 8 it is disposed with in SCR reactor 7，Every layer of catalyst 8 includes four catalyst blocks being arranged side by side.
