Abstract
The utility model relates to a deNOx systems especially relates to a whirlwind disconnect -type deNOx systems. Including boiler, cyclone and filtering component, upper end and the cyclone of boiler be linked together, boiler and cyclone's intercommunication department be equipped with evenly distributed's spray gun, spray gun and the aqueous ammonia be linked together, cyclone's upper portion and filtering component be linked together. Whirlwind disconnect -type deNOx systems simple structure realizes automated control, improves desulfurization effect.
Description
Technical field
The utility model relates to a kind of denitrating system, relates in particular to a kind of cyclone separating denitrating system.
Background technology
The burning of at present traditional boiler is mainly with coal, and wherein coal-fired power plant is the discharge rich and influential family of China's consumption coal and sulfur dioxide and nitrogen oxide, causes the pollution of environment, and production cost is high simultaneously.
Desulfuration in furnace technology the sixties in last century France start to be applied to smoke processing system, because desulfurization degree is only at 15%-40%, and be not used widely. Reason be agstone in boiler furnace, CaCO3Resolve into rapidly CaO, newborn calcined product specific surface can reach ten square metres every gram, thereby can be the high speed of inhaling sulphur process very favourable condition is provided. But then, under high temperature, can there is again sintering in CaO, occur grain coarsening, the phenomenon that specific surface sharply declines.
Chinese patent CN201020653537.5, a kind of chain type boiler Special square desulfurizing dust-collector is disclosed, sidepiece at the first impacting desulfurization dirt pocket with gas approach is set up in parallel the second impacting desulfurization dirt pocket, and setting and described the second impacting desulfurization dirt pocket steam-water separation chamber arranged side by side, the top seal two bottom sides of described the second impacting desulfurization dirt pocket communicates with the first desulfurization dust chamber and steam-water separation chamber respectively, the top of described steam-water separation chamber is interval with the liquid barrier of three layers from bottom to top, and the topmost of steam-water separation chamber is exhanst gas outlet; The atomizer spraying is down located at the top of described the first impacting desulfurization dirt pocket. This structure desulfurized effect is poor.
Summary of the invention
The utility model is mainly to solve the deficiencies in the prior art, provides a kind of simple in structure, and the high cyclone separating denitrating system of desulfuration efficiency.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of cyclone separating denitrating system, comprise boiler, cyclone separator and filter assemblies, the upper end of described boiler is connected with cyclone separator, described boiler and the connectivity part of cyclone separator are provided with equally distributed spray gun, described spray gun is connected with ammoniacal liquor, and the top of described cyclone separator is connected with filter assemblies;
Described filter assemblies comprises filtration tank, the top of described filtration tank is connected with the top of cyclone separator, the upper end of described filtration tank is provided with high-temperature economizer, the lower end of described filtration tank is provided with low-level (stack-gas) economizer, between described high-temperature economizer and low-level (stack-gas) economizer, be provided with catalyst spray assembly, the top of described catalyst spray assembly is provided with soot blower, and described soot blower is connected with compressed air.
As preferably, described high-temperature economizer, catalyst spray assembly, low-level (stack-gas) economizer are upper and lower interval shape and distribute.
Therefore, cyclone separating denitrating system of the present utility model, simple in structure, realize automation control, improve desulfurized effect.
