The flue gas desulfurization drying device significantly reduces the pollution of industrial emissions to the atmospheric environment and ecological environment, and provides important technical solutions for protecting the environment and promoting sustainable development.

[0003] After searching the existing published technical documents, the Chinese patent publication number CN218393024U discloses a flue gas desulfurization drying device. The drying device mainly starts the exhaust fan, accelerates the air flow rate in the flue gas treatment pipe, and draws the gas from the outlet pipe into the exhaust channel of the treatment block. When the gas encounters the turning point of the exhaust channel, the gas collides with the absorbent cotton, and the absorbent cotton absorbs the moisture in the gas. The gas is drawn out of the exhaust channel by the exhaust fan and finally discharged from the outlet of the flue gas treatment pipe. However, the drying device has the following defects:

[0004] When the drying device dries the desulfurized flue gas, it needs to absorb water through absorbent cotton. When the absorbent cotton absorbs a lot of water, it needs to be replaced.

[0008] When the technical solution is in use, the reduction motor drives the screw rod to rotate forward, and the screw rod drives the sleeve slider to move right under the action of the thread transmission force. The sleeve slider drives the switching motor to move right, and the switching motor drives the rotating shaft to move the rotating rod right. The rotating rod carries multiple sleeves to achieve synchronous right movement. Multiple sleeves carry two rotating motors to move right respectively. The rotating motor drives the rotating block to move right. The rotating bar drives the rotating bar to move the positioning plate to the right along the inner wall of the desulfurization drying box. At the same time, the positioning plate drives the two positioning blocks to move right, and the positioning block drives the drying plate to move right out of the desulfurization drying box.

[0015] The present invention has the following beneficial effects:

The replacement efficiency is greatly improved, and the flue gas desulfurization and drying device is more convenient and efficient to maintain.

[0017] Furthermore, the present invention utilizes a rotating positioning component, and the electric cylinder carries the locking block to shrink, so that the locking block no longer squeezes the locking rotating strip, and at the same time, the rotating motor is started, and the rotating motor drives the rotating block to rotate downward by 100 degrees.

Then, when the pressure sensor value of the pressure sensor is the same as the pressure value set by the controller, the controller starts the reduction motor to drive the screw to reverse. Finally, the drying plate and the positioning plate are automatically separated, and the used drying plate is automatically separated. In summary, there is no need to replace the cover doors one by one, which greatly improves efficiency and makes the maintenance of the flue gas desulfurization drying device more convenient and efficient.

[0044] The working principle of the flue gas desulfurization drying device of the present invention is:

[0045] 1) During drying, the cover door 12 is closed, and the cover door 12 is connected and closed with the desulfurization drying box 1. By docking the docking flange 15 on the desulfurization flue gas pipeline, the desulfurization flue gas enters the inside of the booster fan 14 along the docking flange 15. The controller 11 starts the booster fan 14, and the booster fan 14 pressurizes the air and then pours the desulfurization flue gas into the desulfurization drying box 1, and generates steam after being heated by multiple resistance heating rods 13. The steam is adsorbed and dried along multiple drying plates 25, and the dried air is discharged to the next desulfurization pipeline along multiple exhaust pipes 10 to achieve the desulfurization flue gas drying operation.

[0046] 2) During switching, when multiple drying plates 25 need to be replaced, the controller 11 can be used to start the reduction motor 9, which drives the screw 8 to rotate forward, and the screw 8 drives the sleeve slider 7 to move right under the action of the thread transmission force. At the same time, the sleeve slider 7 moves right along the inner wall of the slide frame 2 under the action of the thread, and the sleeve slider 7 drives the switching motor 3 to move right, and the switching motor 3 drives the rotating shaft 4 to move the rotating rod 5 to the right. The rotating rod 5 carries multiple sleeve plates 6 to achieve synchronous right movement, and the multiple sleeve plates 6 respectively carry two rotating motors 16 to move right, and the rotating motor 16 drives the rotating block 20 to move right, and the rotating bar 21 drives the rotating bar 21 to make the positioning plate 24 move right along the inner wall of the desulfurization drying box 1. At the same time, the positioning plate 24 drives the two positioning blocks 26 to move right, and the positioning block 26 drives the drying plate 25 to move right out from the inside of the desulfurization drying box 1. Then, the switching motor 3 is started to drive the rotating shaft 4 to rotate 180 degrees, the rotating shaft 4 drives the rotating rod 5 to rotate 180 degrees, and the rotating rod 5 drives the multiple sleeve plates 6 to rotate 180 degrees, so that the new rotating strip 21 can be rotated to the left.

[0047] 3) During positioning sensing, the switching motor 3 is moved rightward to squeeze the rubber block 30, and the rubber block 30 drives the squeezing block 29 to move rightward to squeeze, and the squeezing block 29 drives the guide column 28 to move rightward, and the guide column 28 moves rightward along the inner wall of the sliding sleeve block 27, and at the same time, the guide column 28 squeezes on the pressure sensor 31, and the support block 32 is supported by the reduction motor 9, and the support block 32 supports the pressure sensor 31, and the pressure sensor 31 can realize pressure sensing of the guide column 28. When the pressure sensing value of the pressure sensor 31 is the same as the pressure value set by the controller 11, the reduction motor 9 is started by the controller 11 to drive the screw 8 to reverse, so that the sleeve slider 7 drives the switching motor 3 to move leftward, and the switching motor 3 drives the rotating shaft 4 to move the rotating rod 5 to the left, and the rotating rod 5 drives multiple sleeve plates 6 to move leftward. The sleeve plate 6 drives the new drying plate 25 to be inserted into the desulfurization drying box 1, and at the same time, the new frame strip 22 squeezes the new sealing strip 23, and the new sealing strip 23 is squeezed and fitted on the desulfurization drying box 1 to achieve sealing.

[0048] 4) During rotation positioning, the electric cylinder 17 and the locking block 19 are contracted, and the locking block 19 no longer squeezes and locks the rotating strip 21. At the same time, the rotating motor 16 is started, and the rotating motor 16 drives the rotating block 20 to rotate downward by 100 degrees, and drives the rotating strip 21 to rotate through the rotating block 20. The rotating strip 21 drives the positioning plate 24 to rotate the two positioning blocks 26 downward, and the drying plate 25 automatically rotates and moves downward under the action of gravity, and the drying plate 25 and the positioning plate 24 are automatically separated.
