The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a fluidized bed furnace system acid flue gas purification device, includes first body, second body and third body, the gas outlet of first body with the air inlet intercommunication of second body, the gas outlet of second body with the air inlet intercommunication of third body, along the gas flow direction, the diameter of first body reduces gradually, the diameter of second body air inlet end increases gradually, the diameter of second body air outlet end reduces gradually, third body air inlet direction with third body inner wall tangential direction is unanimous.
Specifically, the inclination of the second body air inlet end side wall is greater than the inclination of the first body side wall.
Specifically, a first dust outlet is arranged in the middle of the second body.
Specifically, the air inlet of the third body is located in the middle of the third body, the bottom of the third body is of a conical structure, and a second dust outlet is formed in the bottom of the third body.
Specifically, the air outlet of the second body is communicated with the air inlet of the third body through a fan.
Specifically, the air outlet end of the second body is provided with a baffle.
Specifically, a filter screen is arranged at the top of the third body.
The utility model has the advantages that: the utility model provides a fluidized bed furnace system acid flue gas purification device, includes first body, second body and third body, the gas outlet of first body with the air inlet intercommunication of second body, the gas outlet of second body with the air inlet intercommunication of third body, along the gas flow direction, the diameter of first body reduces gradually, the diameter of second body air inlet end increases gradually, the diameter of second body air outlet end reduces gradually, third body air inlet direction with third body inner wall tangential direction is unanimous. Inside the flue gas got into the second body through first body, reduced earlier at the inside gas velocity of flow of second body, the dust takes place first sedimentation separation, then makes the flue gas velocity of flow increase, takes place centrifugal separation in the third body is inside, and the dust is once more separated and is subsided. The utility model relates to a rationally, simple structure, convenient operation, flue gas dust collection efficiency are good, reduction in production cost.

Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1, the flue gas purification device for acid making in a fluidized bed furnace of the embodiment includes a first body 1, a second body 2 and a third body 3, the gas outlet of the first body 1 and the gas inlet of the second body 2 can be communicated through a connecting pipe, the gas outlet of the second body 2 and the gas inlet of the third body 3 can be communicated through a connecting pipe, along the gas flow direction, the diameter of the first body 1 is gradually reduced, the diameter of the gas inlet end of the second body 2 is gradually increased, the diameter of the gas outlet end of the second body 2 is gradually reduced, and the direction of the gas inlet of the third body 3 is consistent with the tangential direction of the inner wall of the third body 3. The first body 1 is communicated with an acid making flue gas outlet of the fluidized bed furnace, when flue gas enters an air inlet end of the second body 2 through the first body 1, the flow velocity of the flue gas is reduced, dust in the flue gas is separated from gas, and the dust is settled; the flue gas after first settlement increases the velocity of flow of flue gas through the end of giving vent to anger of second body 2, then gets into and carries out centrifugal separation in the third body 3, makes the dust in the gas further subside, and the dust of separation flows out from third body 3 bottom, and clean gas is discharged from the gas outlet at third body 3 top.
The inclination of the side wall of the air inlet end of the second body 2 is greater than that of the side wall of the first body 1, so that the flow speed of air in the process of entering the second body 2 can be slowed down, and the air and dust can be conveniently separated.
The middle part of the second body 2 is provided with a first dust outlet 21, and dust separated in the second body 2 can be discharged from the first dust outlet 21.
The air inlet of third body 3 is located the middle part of third body 3, 3 bottoms of third body are the toper structure, 3 bottoms of third body are provided with second dust outlet 31, and the dust that subsides after centrifugal separation in third body 3 can be followed second dust outlet 31 and discharged.
The gas outlet of the second body 2 is communicated with the gas inlet of the third body 3 through the fan 4, the flow velocity of gas entering the third body 3 can be increased through the fan 4, and centrifugal separation of the smoke in the third body 3 is facilitated.
The air outlet end of the second body 2 is provided with a baffle 5, so that dust settled in the second body 2 can be prevented from being discharged through the air outlet of the second body 2.
The top of the third body 3 is provided with a filter screen 6 which can further filter gas.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
