Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization towers, in particular to a desulfurization tower plate. Background Art

[0002] In the process of desulfurizing flue gas by using a desulfurization tower, tower plates are often used to disturb the gas flowing in the desulfurization tower and evenly distribute the flue gas, so that the flue gas and the liquid sprayed in the desulfurization tower are fully in contact with each other to promote the mass transfer effect between them; most of the tower plates used for gas uniform distribution in the prior art directly and evenly open air holes on the plate body, or directly set the base surface of the plate body to a mesh structure, so as to achieve the purpose of even distribution and disturbance of the flue gas, thereby achieving full contact between the flue gas and the spray liquid, and improving the effect of the contact reaction between them.

[0003] However, since the flue gas usually flows from bottom to top, the degree of turbulence on the flue gas is limited by simply setting up vertically penetrating pores or meshes on the plate body, and it is difficult to ensure sufficient contact between the spray liquid and the flue gas, resulting in low mass transfer efficiency. In addition, after the spray liquid contacts the flue gas, the liquid will move downward along the pores or meshes on the plate body and drip. After being moistened by the liquid, the solid particles contained in the flue gas will accumulate on the surface of the plate body and block some of the pores or meshes, resulting in a decrease in the flue gas circulation efficiency and uniform distribution effect, requiring frequent cleaning and maintenance, which invisibly increases the labor intensity and reduces work efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a desulfurization tower plate, which can increase the turbulence of the flue gas, make the flue gas flow evenly upward, provide favorable conditions for full contact between the gas and the spray liquid, improve the mass transfer efficiency and mass transfer effect, and at the same time extend the frequency of cleaning the tower plate to ensure work efficiency.

[0005] The utility model adopts the following technical solutions:

[0006] A desulfurization tower plate comprises a plate body, wherein a plurality of air holes are formed through the plate body, each of the air holes is connected to a uniform cover, the uniform cover is extended upward, and mesh holes are formed through the uniform cover; when working, flue gas enters from the bottom of the air hole and flows out from the mesh holes on the uniform cover.

[0007] Preferably, the uniform distribution cover is a mesh cylindrical structure.

[0008] Preferably, the top end of the uniformly distributed cover is sealed.

[0009] Preferably, the top of the uniformly distributed cover is an arc-shaped top surface.

[0010] Preferably, a swirl plate is provided at the air hole at the bottom of the plate body, a fan blade is rotatably provided inside the swirl plate, a driving rod is provided at the axis of the fan blade, and a cleaning brush is provided on the driving rod and extends to the inner wall of the uniform distribution cover.

[0011] Preferably, two cleaning brushes are provided.

[0012] Preferably, a sleeve extending downward is provided at the air hole at the bottom of the plate body, the swirl plate is arranged at the bottom end of the sleeve, and a drainage hole is provided on the sleeve.

[0013] Preferably, the drainage holes are arranged in a plurality of groups, and the drainage holes at the lowest position are located above the fan blades.

[0014] Preferably, the drainage holes are arranged obliquely downward.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the utility model can not only increase the disturbance of the flue gas, make the flue gas flow upward uniformly, provide favorable conditions for the full contact between the gas and the spray liquid, and improve the mass transfer efficiency and mass transfer effect, but also extend the frequency of cleaning the tower plate to ensure work efficiency. Specifically, by setting the uniform hood, the flue gas can flow out from multiple directions of the uniform hood, increasing the degree of disturbance of the flue gas, allowing the flue gas to fully contact with the spray liquid, thereby improving the mass transfer efficiency and mass transfer effect; at the same time, by extending the uniform hood upward, the length of the flue gas discharge channel is increased, which can provide a certain space for the accumulation of solid particles, avoiding the workload caused by frequent shutdowns for cleaning, extending the continuous operation time of the equipment, and ensuring work efficiency.

[0019] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:

[0020] like Figures 1 to 3As shown, a desulfurization tower plate described in the utility model includes a plate body 1, which is a disc-shaped structure matching the inner diameter of the desulfurization tower, and the plate body 1 can be selected to be an integrated or split type according to the size of the inner diameter of the desulfurization tower, so as to be installed inside the desulfurization tower; a plurality of air holes are opened through the plate body 1, and each air hole is connected to a uniform cover 2, which can be fixedly connected to the air hole or detachably connected to the air hole for subsequent targeted inspection and maintenance; mesh holes are set through the uniform cover 2, and the uniform cover 2 is used to guide the flue gas evenly upward for discharge, The flue gas and the spray liquid are fully mixed and contacted; the uniform cover 2 is extended upward to increase the length of the flue gas discharge channel, which can provide a certain storage space for the accumulation of solid particles in the flue gas after the flue gas contacts the spray liquid, avoiding the workload caused by frequent shutdowns for cleaning, extending the continuous operation time of the equipment, and ensuring work efficiency; when working, the flue gas enters from the bottom of the pores and flows out from the mesh holes on the uniform cover 2, increasing the disturbance of the flue gas, ensuring that the clumped flue gas is broken up after passing through the uniform cover 2, and making the flue gas flow upward evenly to achieve full contact with the spray liquid.

[0021] Furthermore, the uniform cover 2 is preferably configured as a mesh cylindrical structure, and smoke can be discharged on each side thereof, which can increase the turbulence of the smoke, break up the clumped smoke, and make the smoke flow upward uniformly; wherein, the top of the uniform cover 2 is sealed to ensure that the smoke is discharged from the side of the uniform cover 2, which can effectively increase the degree of disturbance of the smoke after being discharged from the uniform cover 2, so that the smoke and the spray liquid can be fully mixed and collided. In addition, the top of the uniform cover 2 is preferably configured as an arc-shaped top surface, which helps the spray liquid to slide smoothly and prevents the spray liquid from accumulating on the top of the uniform cover 2.

[0022] Furthermore, a swirl plate 3 is provided at the air hole at the bottom of the plate body 1, and a plurality of swirl plates 3 are provided, and are arranged at a certain angle at the bottom of the air hole with the center of the air hole as the center of the circle; a fan blade 4 is provided in the swirl plate 3 for rotation, and a driving rod 5 is provided at the axis of the fan blade 4, and a cleaning brush 6 extending to the inner wall of the uniform cover 2 is provided on the driving rod 5. During operation, after the flue gas flow rate is adjusted, the flue gas will enter the air hole through the gap between the swirl plates 3 to form a flue gas vortex, which will drive the fan blade 4 to rotate, and the rotation of the fan blade 4 drives the driving rod 5 and the cleaning brush 6 to rotate, so as to remove the solid particles attached to the uniform cover 2 and ensure the circulation efficiency of the flue gas; in addition, in this embodiment, it is preferred that two cleaning brushes 6 are provided, and the two cleaning brushes 6 are arranged symmetrically to improve the cleaning effect of the inner wall of the uniform cover 2.

[0023] Furthermore, a sleeve 7 extending downward is provided at the air hole at the bottom of the plate body 1, the swirl plate 3 is provided at the bottom of the sleeve 7, and a drainage hole 8 is provided on the sleeve 7. The setting of the drainage hole 8 can help increase the air intake of the smoke; wherein the drainage holes 8 are provided in multiple groups, and the drainage holes 8 at the lowest position are located above the fan blades 4, so as to avoid the smoke entering from the drainage holes 8 from having an adverse effect on the rotation of the fan blades 4. In addition, the drainage holes 8 are preferably arranged obliquely downward, which can guide the flow of the smoke, so that the smoke is obliquely guided upward into the uniform cover 2, which is convenient for the rapid removal of the smoke, and further reduces the adverse effect of the smoke entering from the drainage holes 8 on the fan blades 4, and the structure is simple and practical.

[0024] The utility model increases the turbulence of the flue gas by setting the uniform cover 2, making the flue gas flow upward uniformly, providing favorable regulation for the full contact between the flue gas and the spraying liquid, improving the mass transfer efficiency and mass transfer effect, and at the same time prolonging the frequency of cleaning the tower plate, ensuring work efficiency and reducing labor intensity.
