Description

Technical Field

[0001] This patent relates to the technical field of spray towers, specifically a co-current flue gas desulfurization spray tower. Background Art

[0002] A co-current desulfurization tower means that the high-temperature flue gas flows upward in parallel, and the desulfurization spray flows downward. That is, the smoke inlet pipe is installed on the bottom side of the side wall of the tank body, and most of them are horizontally arranged. The downward injection of the desulfurization liquid easily causes the desulfurization liquid to enter the smoke inlet pipe, thereby affecting the smoke inlet volume of the smoke inlet pipe and the flue gas desulfurization efficiency. For this reason, we propose a co-current flue gas desulfurization spray tower. Utility Model Content

[0003] Aiming at the deficiencies of the prior art, the purpose of this patent is to provide a co-current flue gas desulfurization spray tower. In this patent, an inclined pipe is installed on the lower side of the right side wall of the tank body, and a smoke inlet pipe is installed at the right end of the inclined pipe. The smoke inlet pipe is composed of a first pipe body, a second pipe body, a corrugated pipe and a third pipe body. Spring members are provided on both the upper and lower sides of the first pipe body. Through the spring members, the first pipe body and the third pipe body can be pressed against the left and right sides of the fan. By setting the inclined pipe, it can be avoided that the falling desulfurization liquid enters the smoke inlet pipe and affects the smoke inlet volume, and it is convenient to disassemble the fan through the spring members, facilitating the cleaning of the dust in the fan.

[0004] The technical solution adopted by this patent to solve its technical problems is: a co-current flue gas desulfurization spray tower, including a tank body.

Detailed Embodiments

[0018] The following further elaborates on this patent in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate this patent and not to limit the scope of this patent. In addition, it should be understood that after reading the content taught in this patent, those skilled in the art can make various modifications or alterations to this patent, and these equivalent forms also fall within the scope defined by the appended claims of the application.

[0019] SeeFigure 1 , Figure 2 , Figure 3 and Figure 4 are the schematic structural diagrams of this patent. A co-current flue gas desulfurization spray tower includes a tank body 1. A liquid inlet pipe 2 is embedded at the top of the tank body 1. A flow dividing pipe 3 is fixedly installed at the bottom end of the liquid inlet pipe 2. The number of the flow dividing pipes 3 is multiple. A spray head 4 is fixedly installed at the bottom end of the flow dividing pipe 3. A smoke outlet pipe 5 is embedded at the upper side of the right side wall of the tank body 1. An inclined pipe 6 is embedded at the lower side of the right side wall of the tank body 1. A smoke inlet pipe 7 is fixedly installed at the right end of the inclined pipe 6;

[0020] As Figure 1 , 2 shown, it can be known from the installation state of the inclined pipe 6 that the downward flowing desulfurization liquid can be prevented from entering the smoke inlet pipe 7. Since the inclined pipe 6 is in an inclined state and the height of the smoke inlet pipe 7 is higher than that of the inclined pipe 6, the high-temperature flue gas is not easy to float downward. By arranging a fan 12, it is used to draw flue gas into the tank body 1.

[0021] The smoke inlet pipe 7 includes a first pipe body 8, a second pipe body 9 and a fan 12. The left end of the first pipe body 8 is fixedly installed at the right end of the inclined pipe 6. A corrugated pipe 10 is fixedly installed at the left end of the second pipe body 9. A third pipe body 11 is fixedly installed at the left end of the corrugated pipe 10. Spring members are arranged at both the upper and lower ends of the outer side wall of the first pipe body 8. The right end of the first pipe body 8 and the left end of the third pipe body 11 are respectively in close contact with the left and right ends of the fan 12.

[0022] Specifically, the spring member includes a mounting ring 13 and a mounting plate 14. The mounting ring 13 and the mounting plate 14 are respectively fixedly installed on the first pipe body 8 and the third pipe body 11. A square rod 15 is fixedly installed on the left side surface of the mounting plate 14. The left end of the square rod 15 passes through the mounting ring 13 and is fixedly installed with a connecting plate 16. A spring 17 is sleeved on the side wall of the square rod 15. The left and right ends of the spring 17 are respectively fixedly installed on the connecting plate 16 and the mounting ring 13.

[0023] Figure 3 As shown, the spring 17 is in a compressed state. Through the compression effect of the spring 17, a leftward pressure is exerted on the third pipe body 11 to cooperate with the first pipe body 8 to clamp the fan 12.

[0024] Specifically, plate bodies 18 are fixedly installed at both the upper and lower ends of the outer side wall of the fan 12. A square groove 19 is arranged at the rear end of the plate body 18. The inner side wall of the square groove 19 is sleeved on the side wall of the square rod 15.

[0025] By sleeving the inner side wall of the square groove 19 on the side wall of the square rod 15, at this time, the fan 12 is concentric with the first pipe body 8 and the third pipe body 11, which is used to limit the installation position of the fan 12 and prevent smoke leakage.

[0026] Specifically, sealing rings are installed at the right end of the first pipe body 8 and the left end of the third pipe body 11.

[0027] The sealing rings are high-temperature resistant rubber rings, which are used to increase the sealing performance on both sides of the fan 12.

[0028] Specifically, the corrugated pipe 10 is a high-temperature resistant pipe body.

[0029] Specifically, one end of a connecting rod 20 is fixedly installed at the bottom end of the outer side wall of the second pipe body 9, and the other end of the connecting rod 20 is fixedly installed on the outer wall of the tank body 1.

[0030] The connecting rod 20 is used to keep the second pipe body 9 in a fixed state.

[0031] Working principle: The fan 12 extracts the flue gas in the smoke inlet pipe 7 and enters the tank body 1 through the inclined pipe 6. The spray head 4 sprays the desulfurization agent water mist to carry out desulfurization treatment on the flue gas. After a long time, the fan 12 can be disassembled for cleaning. The third pipe body 11 can be moved to the right, the corrugated pipe 10 is compressed, and the third pipe body 11 and the first pipe body 8 no longer press tightly on both sides of the fan 12. Then, the fan 12 is moved forward for disassembly, and the dust on its fan blades is cleaned.

[0032] It should be noted that the device structure and drawings of this patent mainly describe the principle of this patent. On the basis of this design principle, the settings of the power mechanism, power supply system, control system, etc. of the device are not fully described clearly. However, on the premise that those skilled in the art understand the principle of the above patent, the specific details of its power mechanism, power supply system, and control system can be clearly known.

[0033] In this patent, an inclined pipe is installed at the lower side of the right side wall of the tank body. The right end of the inclined pipe is installed with a smoke inlet pipe, which is composed of a first pipe body, a second pipe body, a corrugated pipe, and a third pipe body. Spring members are provided on both the upper and lower sides of the first pipe body. Through the spring members, the first pipe body and the third pipe body can be pressed tightly on both sides of the fan. By setting the inclined pipe, it can be avoided that the falling desulfurization liquid enters the smoke inlet pipe and affects the smoke intake volume, and it is convenient to disassemble the fan through the spring members, facilitating the cleaning of the dust inside the fan.
