Abstract
The utility model discloses a furnace gas desulfurization system with high desulfurization efficiency. The furnace gas desulfurization system comprises a powder blowing device and a gas dust removing device, wherein the powder blowing device is used for blowing solid desulfurization agents into a sealed furnace gas delivery space, and the receiving end of the gas dust removing device is connected with the discharging end of the furnace gas delivery space. The temperature reduction is not actively carried out on the furnace gas by the furnace gas desulfurization system disclosed by the utility model, and sulfur dioxide in the furnace gas generates adsorption reaction with the solid desulfurization agents under the relatively high temperature, so that the desulfurization efficiency is beneficially improved; and the solid desulfurization agents are removed from the furnace gas by utilizing the gas dust removing device, so that the integration of desulfurization and dust removal is realized.
Description
Technical field
The utility model relates to a kind of furnace gas desulphurization system.
Background technology
The present furnace gas desulfur technology methods of washing under cryogenic conditions that adopt, the efficient of the desulfurization of this method is lower more.
The utility model content
The utility model aims to provide a kind of higher furnace gas desulphurization system of efficient of desulfurization.
Furnace gas desulphurization system of the present utility model comprises: the powder blowing device, and described powder blowing device is for the solid desulfurating agent of jetting to the furnace gas transmission space of sealing; The dedusting device, the receiving terminal of described dedusting device links to each other with the discharge end that described furnace gas transmits the space.
Concrete, described furnace gas transmits the space and refers to from the generation source of furnace gas to the connecting pipe of dedusting device.
Further be that described powder blowing device is provided with at least two along the spaced apart winding-up point of furnace gas direction of transfer.
Further be, described dedusting device adopts pneumatic filter, and this pneumatic filter uses inorganic porous material as its filter element.
Further be that described pneumatic filter uses a kind of as its filter element in titanium-aluminium alloy porous material, ferro-aluminum alloy porous material, the nickel alumin(i)um alloy porous material.
Further be the filtering accuracy of described filter element≤5 μ m.

Further be that described solid desulfurating agent is hydrated ferric oxide powder or compound desulfurizing agent powder.
Further be inlet temperature 〉=300 of described dedusting device receiving terminal ℃.
Further be inlet temperature 〉=450 of described dedusting device receiving terminal ℃.
Because furnace gas desulphurization system of the present utility model initiatively do not lower the temperature to furnace gas, the sulfur dioxide in the furnace gas under higher temperature with the solid desulfurating agent adsorption reaction, help to improve desulfuration efficiency; By the dedusting device solid desulfurating agent is removed from furnace gas then, thereby realized desulfurization and dust removal integrated.
Below in conjunction with the drawings and specific embodiments the utility model is described further.The aspect that the utility model is additional and advantage part in the following description provide, and part will become obviously from the following description, or recognize by practice of the present utility model.
Description of drawings
Fig. 1 is the structural representation of the utility model furnace gas desulphurization system.
The specific embodiment
As shown in Figure 1, furnace gas desulphurization system of the present utility model comprises: powder blowing device 1, and described powder blowing device 1 is for the solid desulfurating agent of jetting to the furnace gas transmission space of sealing; Dedusting device 3, the receiving terminal of described dedusting device 3 links to each other with the discharge end that described furnace gas transmits the space.It can be at the generation source of furnace gas and the intermediate receptacle between the dedusting device 3 that described furnace gas transmits the space, but preferably from the generation source of furnace gas to the connecting pipe 4 of dedusting device 3, in order to furnace gas is contacted with solid desulfurating agent under higher temperature.Solid desulfurating agent storage tank 101 and at least two solid desulfurating agents conveying winding-up pipes 102 that are connected with solid desulfurating agent storage tank 101 respectively that powder blowing device 1 comprises high-pressure air source, is connected with high-pressure air source, these two solid desulfurating agents are carried the output of winding-up pipe 102 to be connected on the connecting pipe 4 but are kept at a certain distance away, thereby make described powder blowing device 1 have two along the spaced apart winding-up point of furnace gas direction of transfer, guarantee that furnace gas fully contacts with solid desulfurating agent, guarantee desulfurized effect.Described dedusting device 3 can adopt gravitational precipitator, cyclone dust collectors etc., but the dust removing effects of these cleaners is not ideal, and therefore pneumatic filter is adopted in suggestion, and this pneumatic filter uses inorganic porous material as its filter element.Described pneumatic filter preferably uses a kind of as its filter element in titanium-aluminium alloy porous material, ferro-aluminum alloy porous material, the nickel alumin(i)um alloy porous material, to guarantee that filter element has higher high-temperature oxidation resistance, guarantee the service life of filter element.Be to guarantee filter effect, the filtering accuracy of described filter element is best≤1 μ m, certainly, requiring under the not too high situation, the filtering accuracy of described filter element can≤5 μ m.In addition, described solid desulfurating agent is preferably hydrated ferric oxide powder or compound desulfurizing agent powder.For guarantee sulfur dioxide in the furnace gas under higher temperature with solid desulfurating agent adsorption reaction, inlet temperature 〉=300 ℃ that can guarantee described dedusting device 3 receiving terminals.Certainly, the inlet temperature of described dedusting device 3 receiving terminals is best 〉=450 ℃, can guarantee like this sulfur dioxide in the furnace gas under higher temperature with the solid desulfurating agent adsorption reaction, improve desulfuration efficiency.
