Description
Technical field
The invention belongs to denitration device technical field, relate to a kind of small-sized denitration device, be specifically related to a kind of integrated form denitration station.
Background technology
Boiler smoke usually contains substantial amounts of nitrogen oxides NOx Such as NO, nitrogen oxides is directly discharged in air meeting contaminated air, forms photochemical fog and acid rain, be detrimental to health, and therefore flue gas has to pass through denitrogenation (i.e. denitration) process before discharge.Along with the increasing of environmental improvement dynamics, current China carries out denitrating flue gas project the most on a large scale.Traditional denitrating system floor space is big, and equipment is complicated, and operating cost is high, and some enterprises having miniature boiler are difficult to accept.
Utility model content
The purpose of this utility model is to provide a kind of integrated form denitration station, to optimize denitrating technique flow process, reduces denitration operating cost, reduces occupation area of equipment.
The technical solution of the utility model is: integrated form denitration station, including holding vessel, dissolving tank, water tank, spraying system and switch board.Holding vessel is provided with urea liquid entrance, urea liquid outlet and urea liquid return port, and dissolving tank is connected to urea liquid entrance by delivery pump.Denitration station is provided with blender, urea solution metering pump and water dosing pump, and urea liquid outlet is connected to the denitrfying agent entrance of blender by urea solution metering pump, and water tank is connected to the water inlet of blender by water dosing pump.Mixer outlet is connected to spraying system, and spraying system includes valve, effusion meter and denitration spray gun, and mixer outlet is connected to denitration spray gun by valve and effusion meter.
Denitration station is provided with relief valve, and the relief valve of leading up to of urea solution metering pump discharge is connected to urea liquid return port.The relief valve of leading up to of water dosing pump outlet is connected to water tank return port.Dissolving tank is provided with agitator and charge door.Water tank is provided with sewage draining exit, and sewage draining exit is provided with valve.Water supply line is connected to dissolving tank and water tank, and connecting line is provided with valve.
This utility model uses the carbamide being safe from harm human body as reducing agent, and solid urea heated and stirred in dissolving tank is dissolved as certain density urea liquid and stores stand-by in delivery pump is delivered to holding vessel.In order to ensure certain eject momentum to reach good atomizing effect and high denitration efficiency, by urea liquid dilute after through spray gun atomized spray.
This utility model optimizes denitrating technique flow process, makes SNCR denitration technology be applied to (below 30t/h) miniature boiler, and denitration efficiency can reach more than 65%, advantageously reduces denitration operating cost more, reduces occupation area of equipment.Integrated form denitration station floor space is little, operating cost is low, it is simple to install, easily operated.
