Detailed description of the invention
Fig. 1 is blast furnace gas Structure of Flue Gas Desulfuration Absorbing schematic diagram of the present invention.
Specific embodiment
Structure and feature of the invention are described in detail with reference to the accompanying drawings and examples.It should be noted that can
To make various modifications to disclosed embodiments, therefore, embodiment disclosed in specification be should not be considered as to the present invention
Limitation, and only as the example of embodiment, the purpose is to keep feature of the invention apparent.
As shown in Figure 1, blast furnace gas desulfurizing tower provided by the invention between level-one rough removing tower 1, second level fine removing tower 2 and tower by connecting
Adapter tube road 3 is constituted, and level-one rough removing tower 1 and second level fine removing tower 2 are arranged side by side, and top is connected by connecting pipe 3 between tower.It is high
Producer gas enters level-one rough removing tower from 1 bottom of level-one rough removing tower, after carrying out first time desulfurization process, through connecting pipe 3 between tower into
After entering second of the desulfurization process of progress of second level fine removing tower 2, exports and export from the bottom blast furnace gas of second level fine removing tower 2.
As shown in Figure 1, the bottom of the level-one rough removing tower 1 is equipped with blast furnace gas entrance 11, in level-one rough removing tower, blast furnace
The top of gas entry, is equipped with an air distributor 12, which can make the blast furnace gas entered in tower uniformly, steadily
Ground is distributed in level-one rough removing tower, increases the area that blast furnace gas is contacted with the sweetening liq of spray, avoids the occurrence of air-liquid unevenness
Caused by the low phenomenon of desulfuration efficiency.
In level-one rough removing tower, the top compartment of terrain of air distributor is equipped with several row's spray guns 13, is densely covered with mist on spray gun
Change nozzle, (such as NaOH) containing buck is sprayed into level-one rough removing tower.It is removed in blast furnace gas and contains CO, CO2、N2Outside, also contain
COS、H2S and Cl-, inventive desulfurization tower is mainly the H removed in blast furnace gas2S and Cl-.When blast furnace gas is through level-one rough removing tower
Bottom enter after, through air distributor 12 to the top of tower drift about, during blast furnace gas drift about upwards, chance spray gun 13 to
Lower sprinkling contains buck, the H in blast furnace gas2S is encountered containing after buck (NaOH), is chemically reacted, and Na is generated2S, Na2S is molten
Yu Shuizhong, this is the first time desulfurization process that this present invention level-one rough removing tower carries out blast furnace gas.
Due to the Cl in blast furnace gas-It is also chemically reacted with what spray gun sprayed downwards containing buck, therefore, the present invention is right
Dechlorination also may be implemented while blast furnace gas desulfurization.
In level-one rough removing tower, blast furnace gas enters from the lower part of tower, goes out from the top of tower, and spray gun spray contains buck
It is sprayed downwards by the top of tower, blast furnace gas is reverse with liquid, and the reaction time is long, and desulphurization reaction is abundant, and desulfuration efficiency is high.
Blast furnace gas after 1 desulfurization process of level-one rough removing tower enters second level fine removing tower 2 through connecting pipe 3 between tower.
As shown in Figure 1, the top in second level fine removing tower 2 also is provided with spray gun 21, one is fixed in the lower section of spray gun 21 and is led
Flow cone 22, the bottom of second level fine removing tower 2 be fixed with one be in an angle of 90 degrees blast furnace gas output channel 23, the blast furnace gas output
Pipeline 23 is connected with the blast furnace gas outlet 24 being arranged on second level fine removing tower wall.
After blast furnace gas after level-one rough removing tower desulfurization process enters second level fine removing tower, contain again through what spray gun 21 sprayed
It is defeated by blast furnace gas outlet 24 through the blast furnace gas output channel 23 in an angle of 90 degrees after deflection cone 22 after buck desulfurization process
Out.
Blast furnace gas in second level fine removing tower uses the design structure of upper entering and lower leaving, is equipped with deflection cone, air-liquid in inlet
After deflection cone is oriented to, most of liquid is separated to tower body inner wall and flows down along the side wall of tower, air-flow to down toward exit be in 90
The blast furnace gas output channel for spending angle, since current density is low and easy turn, second level fine removing tower is right again at outlet conduit
Gas and liquid carry out secondary separation, and the blast furnace gas through desulfurization process twice passes through output channel 23, the blast furnace coal in an angle of 90 degrees
24 output of gas outlet.
To collect the liquid that spray gun 13,21 sprays, as shown in Figure 1, the bottom in level-one rough removing tower 1 and second level fine removing tower 2
Portion is equipped with liquid collection trough 14,25, the leakage fluid dram 15,26 being connected with liquid collection trough.
For convenience of overhaul of the equipments, as shown in Figure 1, the present invention is on 1 side wall of level-one rough removing tower, the side of offering near spray gun 13
The access hole 16 that person who happens to be on hand for an errand enters and leaves is laid with inspection platform 17 in tower near spray gun.Equally, on the side wall of second level fine removing tower 2, spray
Rifle 21 nearby offers the access hole 27 for facilitating people to enter and leave, and is laid with inspection platform 28 near spray gun in tower.The connecting tube between tower
Road 3 is equipped with coal gas diffusing device 4, and gas displacement is carried out when convenient for going into operation and overhaul.
In the specific embodiment of the invention, the air distributor being arranged in level-one rough removing tower is a steel grating,
Aperture size, which is subject to, not to be influenced air-flow and passes through, and can be combed to air-flow, is evenly distributed on gas in tower, and with spray
Sweetening liq come into full contact with, to improve gas liquid interfacial area, improve desulfuration efficiency.
An elbow is equipped at the level-one rough removing tower blast furnace gas entrance 11, blast furnace gas enters through inlet pipeline, elbow
In tower, coal gas is avoided directly to wash away tower wall, extends the service life of tower.
As shown in Figure 1, each tower is equipped with support 5, is supported for tower body, facilitate installation.
Constitute level-one rough removing tower and second level fine removing tower of the invention diameter, highly according to blast furnace coal tolerance to be processed and
Design, in general, the flow velocity of blast furnace gas is 4-5 meter per second in level-one rough removing tower, the coal gas residence time about 10 seconds, second level essence was de-
