Abstract
The utility model discloses a kind of fume desulfurating absorption towers with twin-stage airflow distribution device, it include tower body, slurry pool positioned at tower body bottom, twin-stage airflow distribution device, spray tube and the demister being sequentially arranged above slurry pool in tower body and from bottom to up；The absorption tower entrance being connected to slurry pool is provided on tower body, the top of tower body is provided with absorption tower outlet.The utility model is realized to the rectification for entering tower flue gas and is evenly distributed with by twin-stage airflow distribution device, when flue gas passes through twin-stage airflow distribution device, gas-liquid generates strong shock effect: during absorbing slurry drops whereabouts, when passing through twin-stage airflow distribution device, drop is accelerated upward flue gas and smashes again, generates new mass transfer sorbent surface, equivalent to increase one layer of spraying layer without circulating pump, mass transfer efficiency and absorption efficiency are improved, operation energy consumption is saved.
Description
Technical field
The utility model relates to field of environment protection equipment, specifically a kind of flue gas desulfurization with twin-stage airflow distribution device is inhaled
Receive tower.
Background technique
In recent years, Wet Calcium-Based Flue Gas Desulfuriation Technolo Gies are since its is safe and reliable to operation, desulfuration efficiency is high, sorbent utilization
The advantages that height, strong applicability, is widely used.Hollow-spraying-tower device because its tower inner member is few, desulphurization plant is less scaling and
Blocking, the pressure loss is also smaller, operation and maintenance are relatively simple, currently, having become the first choice in desulfurization project at home and abroad.
After flue gas enters absorption tower gas-liquid mixed area, with the absorbent slurry (stripping liquid slurries) under spraying layer spray
Reverse contact mixing, wherein between stripping liquid slurries mass exchange occurs for the most gaseous state roatating packed beds carried
When and be dissolved in absorbent slurry, to complete gaseous state SO2Physical entrapment process, absorbing reaction rate and efficiency are main
Depending on the relative velocity of flue gas and slurries, contact area, many factors such as residence time.Conventional absorption tower is due to air flow method
Unevenness, to reduce desulfuration efficiency.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of, and the flue gas desulfurization with twin-stage airflow distribution device is inhaled
Tower is received, when flue gas passes through the twin-stage airflow distribution device in absorption tower, air-flow cross section in tower is evenly distributed with, and is effectively improved
Desulfuration efficiency.
The technical solution of the utility model are as follows:
A kind of fume desulfurating absorption tower with twin-stage airflow distribution device, includes tower body, the slurry positioned at tower body bottom
Liquid pool, twin-stage airflow distribution device, spray tube and the demister being sequentially arranged above slurry pool in tower body and from bottom to up；
The absorption tower entrance being connected to slurry pool is provided on the tower body, the top of the tower body is provided with absorption tower outlet.
The twin-stage airflow distribution device includes the second level airflow distribution device of sieve tray structure and is connected to the
It is the first order airflow distribution device of deflector structure immediately below secondary air flow distribution apparatus.
The first order airflow distribution device includes multiple parallel deflectors, the top of multiple deflectors and its
The second level airflow distribution device of top is fixedly connected, the absorption tower entrance of the bottom end of multiple deflectors obliquely downward.
The second level airflow distribution device is to be arranged in parallel in the intracorporal sieve tray of tower, and the pore size of sieve tray is
30-60mm。
The spray tube includes multilayer or more spray tube disposed in parallel, is provided with multiple courts on each spray tube
To the nozzle of underface.
The advantages of the utility model:
The utility model carries out deep in many factors such as relative velocity, contact area, residence times to flue gas and slurries
Enter on the basis of researching and analysing, twin-stage airflow distribution device is designed in conventional spray absorber, flue gas is by first order air-flow point
Cloth apparatus enters second level airflow distribution device, obtains secondary fining distribution, it is ensured that and flue gas cross section in tower is completely uniformly distributed,
It is again broken — that is, two that upward flue gas is accelerated when through twin-stage airflow distribution device from the drop that spray tube falls simultaneously
It is secondary broken, generate new mass transfer sorbent surface, to effectively increase gas liquid interfacial area, equivalent to increase one layer without
The spraying layer of circulating pump improves mass transfer efficiency and absorption efficiency, saves operation energy consumption；The utility model first order air flow method
The bottom end of device is moved upwards in a manner of " plug flow " after entering flue gas in tower towards absorption tower entrance, makes air-flow in tower
It is inside tentatively distributed, avoids conventional void tower inevitably " vortex " phenomenon.
