Description

Technical fields:

[0001] This utility model relates to the field of filtration technology, specifically to a filtration mechanism for a desulfurization cooler. Background technology:

[0002] When flue gas needs desulfurization, it is introduced into the desulfurization tower. Multiple spray devices at the top of the tower spray out desulfurization slurry, causing it to come into countercurrent contact with the flue gas. This allows the slurry to absorb sulfides from the flue gas. The high-temperature desulfurization slurry then flows back to the bottom of the tower. Multiple slurry pipes connected to the bottom of the tower transport the slurry to the filter chamber. After the filter chamber removes solid particles, the slurry enters a cooler for cooling to prevent particles from depositing, clogging, or scaling. Finally, the cooled slurry is pumped back to the desulfurization tower for recycling.

[0003] The existing filter chamber mainly consists of a chamber body and a filter plate. The filter plate is fixed to the inner wall of the chamber to filter solid particles contained in the slurry. The chamber body and the filter plate are fixedly connected, which prevents the filter plate from vibrating. Solid particles easily adhere to the surface of the filter plate, hindering the flow of the slurry and reducing the amount of slurry passing through the filter plate per unit time, resulting in a reduction in the slurry flow rate of the cooler. Utility Model Content:

[0004] Therefore, the purpose of this utility model is to provide a desulfurization cooler filtration mechanism to overcome the problems of the existing technology, which mainly consists of a cavity and a filter plate. The filter plate is fixed on the inner wall of the cavity to filter solid particles contained in the slurry. The cavity and the filter plate are fixedly connected, which prevents the filter plate from vibrating. Solid particles easily adhere to the surface of the filter plate, hindering the flow of the slurry and reducing the amount of slurry passing through the filter plate per unit time, resulting in a reduction in the slurry flow rate of the cooler.

[0018] To make the objectives and advantages of this utility model clearer, the utility model will be further described below with reference to the embodiments; it should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model.

[0019] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0021] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] like Figures 1-3 As shown, this utility model provides the following technical solution: a desulfurization cooler filtration mechanism, including a cooler 1, a cavity 2 fixedly connected to the side end of the cooler 1, a liquid pipe fixedly connecting the bottom end of the cooler 1 and the cavity 2, a slag discharge pipe with a valve fixedly connected to the bottom end of the cavity 2, a cylinder 4 slidably fitted inside the cavity 2, a filter plate 5 fixedly connected inside the cylinder 4, a drive assembly fixedly connected to the inner wall of the cavity 2, the output end of the drive assembly fixedly connected to the surface of the cylinder 4, and the output end of the drive assembly can drive the filter plate 5 to vibrate through the cylinder 4.

[0023] Please combine Figure 1As shown, during operation, multiple slurry pipes connected to the bottom of the desulfurization tower transport the desulfurization slurry to the chamber 2. The controller activates the drive assembly, which vibrates the cylinder 4, causing the filter plate 5 to vibrate. After being filtered by the filter plate 5 in the chamber 2, the slurry enters the cooler 1 through the liquid flow pipe at the bottom of the chamber 2. The filter plate 5 filters out the solid particles contained in the slurry, causing them to be blocked on the side surface of the filter plate 5. The vibration of the cylinder 4 causes the solid particles adhering to the side surface of the filter plate 5 to fall off. The solid particles fall to the inner bottom surface of the chamber 2. The valve on the slag discharge pipe fixedly connected to the bottom of the chamber 2 is opened intermittently to discharge the solid particles from the inner bottom surface of the chamber 2. After the solid particles are discharged, the valve is closed, increasing the slurry throughput per unit time through the filter plate 5, thereby increasing the slurry flow rate into the cooler.

[0024] The filter plate 5 is inclined and the inclination direction is downward along the direction close to the slag discharge pipe, which increases the surface area of ​​the filter plate 5 in the cylinder 4, thereby increasing the filtration area of ​​the filter plate 5 for the slurry.

[0025] The surface of the filter plate 5 is an annular corrugated surface. The height of the corrugated surface of the filter plate 5 gradually decreases along the direction away from the center of the filter plate 5, thereby increasing the surface area of ​​the filter plate 5 in the cylinder 4 and thus increasing the filtration area of ​​the filter plate 5 for the slurry.

[0026] The cross-section of the cylinder 4 near the slag discharge pipe end is funnel-shaped, which facilitates the discharge of blocked solid particles along the cylinder 4 to the inner bottom surface of the cavity 2.

[0027] Please combine Figure 1 As shown in the embodiment of the drive assembly, the drive assembly includes a groove 6 formed in the inner wall of the cavity 2, a slider 7 is slidably disposed in the groove 6, the bottom end of the slider 7 is slidably inserted into and matched with the dovetail groove 9, the dovetail groove 9 is formed in a ring on the outer wall of the cylinder 4, a compression spring 8 is fixedly connected between the slider 7 and the cavity 2, the compression spring 8 is disposed in the groove 6, and a vibrator 10 is fixedly embedded in the side end of the slider 7.

[0028] Please combine Figure 1 As shown, during use, when the filter plate 5 needs to vibrate, the controller is operated to make the vibrator 10 work. The vibrator 10 drives the slider 7 to vibrate and compress the spring 8 to deform. The slider 7 drives the dovetail groove 9 to vibrate, the dovetail groove 9 drives the cylinder 4 to vibrate, and the cylinder 4 drives the filter plate 5 to vibrate, thereby shaking off the solid particles on the surface of the filter plate 5 and increasing the amount of slurry passing through the surface of the filter plate 5 per unit time.

[0029] A motor 11 is fixedly connected to the side wall of the cavity 2. The output end of the motor 11 passes into the cavity 2 and is fixedly connected to a slide rod 12. The output end of the motor 11 is rotatably connected to the cavity 2. A barrel 13 is slidably sleeved on the slide rod 12. The side wall of the barrel 13 is fixedly connected to the center of the side wall of the filter plate 5.

[0030] Please combine Figure 1 As shown, during use, the operating controller causes the vibrator 10 to work and the motor 11 to start working simultaneously. The output end of the motor 11 drives the slide bar 12 to rotate, the slide bar 12 drives the barrel 13 to rotate, the barrel 13 drives the filter plate 5 to rotate, and the filter plate 5 drives the solid particles on its surface to rotate. The solid particles are thrown off due to centrifugal force, increasing the amount of slurry passing through the surface of the filter plate 5 per unit time. The sealing ring 14 ensures the sealing between the output end of the motor 11 and the cavity 2.

[0031] The vibrator 10 indirectly drives the filter plate 5 to vibrate, and the filter plate 5 drives the barrel 13 to slide on the slide rod 12.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
