Description
Technical field
The utility model is related to technical field of waste gas treatment, especially a kind of glass furnace SCR denitration flue-gas temperature control dress
It sets.
Background technology
Best results when SCR denitration device requires to react at 350 ~ 380 DEG C to flue-gas temperature, when temperature is higher than 380 DEG C
When, catalyst life shortens, and denitration effect is poor.After glass melter operation after 3 ~ 5 years, the flow and temperature of flue gas increase, into
The temperature for entering SCR denitration device is more than design temperature.To meet the temperature of SCR denitration device, cold wind is needed out, cigarette is not only influenced
The operating mode of gas afterheat utilizing system and flue gas purification system affects the utilization ratio of cogeneration.In order to reduce glass furnace fortune
Influence of the row later stage to smoke waste heat utilization system and flue gas purification system should increase flue-gas temperature control before SCR denitration device
Device processed.
Invention content
The utility model proposes a kind of glass furnace SCR denitration flue-gas temperature control device, can to glass furnace flue-gas temperature into
Row control can utilize fume afterheat in favor of purification.
The utility model uses following technical scheme.
A kind of glass furnace SCR denitration flue-gas temperature control device, the control before being handled for denitrating flue gas to flue-gas temperature,
The control device includes input terminal, cooling channel, bypass channel and output end；The cooling channel, bypass channel with it is defeated
Enter end, output end is connected；The cooling channel is sequentially with smoke inlet, heat dump, exhanst gas outlet on flue gas travel path；
Smoke inlet, smoke outlet are equipped with baffle board door of flue；The bypass channel is in parallel with cooling channel.
The heat dump includes evaporator and superheater；Baffle board door of flue is equipped at the bypass channel.
The heat dump is connected with waste heat boiler of glass furnace drum；Drum returns again after pipeline is heated water input evaporator
It flow to drum；Drum is sent again after saturated vapor input superheater is heated to steam turbine.
The input terminal of the control device is communicated with pipeline after the high temperature section of waste heat boiler of glass furnace.
The control device output end exports flue gas to high temperature electrostatic deduster, SCR denitration device.
The utility model can control flue-gas temperature, and enter cooling channel provided with bypass channel to control
Flue gas quantity, therefore energy flexible adaptation glass furnace exports exhaust gas volumn, preferably meets the needs of denitrating flue gas.
