2Content is usually at 300-5000ppmv (1000-15000mg/Nm
3) between.But exhaust gas volumn is very huge, and the opinion with coal-burning boiler, steam scale are from 35T/h to 2500T/h, and generating set capacity 6MW is to 1000MW, and exhaust gas volumn is by 50,000 Nm
3/ h to 250 ten thousand Nm
3, SO
21000 tons/year to 100,000 tons/year of discharge capacitys.Because SO
2Be sour gas, adopt alkaline aqueous solution except that the SOx in the smoking gas, i.e. flue gas sulphur removal (Flue Gas Desulfurization, FGD) be effective method, be with a wide range of applications.
Synthetic ammonia is alkaline matter, as sulfur elimination, can produce the ammonium sulfate fertilizer of high fertilizer efficiency.This method is called the ammonia process sulfur removal technology.
Three steps of ammonia process sulfur removal technology correspondence are as follows:
(1) SO
2Absorb, show as the acid-base reaction in the aqueous solution, at first generate ammonium sulfite, react as follows:
SO
2+ H
2O+2NH
3=(NH

Because coal or oil are the boiler or the thermal power plant discharged flue gas amount of fuel, and be very huge.Such as, the exhaust gas volumn of a 600MW unit can reach 2,400,000 Nm
3More than/the h, the cross-sectional area of flue tube can reach 100m
2, if adopt round tube, diameter can reach 10m.Obviously, the device that reclaims oxysulfide is if adopt circular smoke inlet, and it highly will significantly increase, and the difficulty of device fabrication is also very big, and cost is very high.Therefore, how reducing device fabrication difficulty and investment, is the problem that this area is extremely paid close attention to.
Summary of the invention
The utility model technical issues that need to address are to disclose a kind of absorption plant that is provided with the recovery oxysulfide of rectangle flue gas interface, to overcome the defective that prior art exists.
The absorption plant that is provided with the recovery oxysulfide of rectangle flue gas interface of the present utility model comprises:

Be arranged on the uptake zone of absorption liquid distributor below;
Be arranged on the middle part flue gas interface of below, uptake zone, the cross sectional shape of said middle part flue gas interface is a rectangle;
Be arranged on the absorption liquid storage area of flue gas interface below, middle part;
The utility model is operation like this:
The flue gas that contains oxysulfide enters tower body from a flue gas interface, and absorption liquid evenly sprays by sulphur removal absorption liquid distributor, contact closely with absorption liquid in the uptake zone, and with the oxysulfide in the flue gas, mainly be sulfur dioxide wherein, become ammonium sulfite.The absorption liquid that has absorbed oxysulfide enters the absorption liquid storage area of bottom, and the air oxidation that is blasted is an ammonium sulfate, and therefore, this slurries storage area also can be called zoneofoxidation; And after ammonium sulfate concentrations accumulation and surpassing its solubility, can crystallization separate out, so the slurries storage area has the function of ammonium sulfate crystallization simultaneously, also can be called the oxidizing and crystallizing district.
The flue gas that has been absorbed oxysulfide leaves absorption plant from another interface.
Middle part of the present utility model flue gas interface has adopted the rectangle interface, and therefore the longest diameter that can reach tower body of the length of rectangular aperture, can significantly reduce the total height of tower body, reduces cost.
