Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization tower support beams, and specifically discloses a stabilizing device for desulfurization tower support beams. Background Art

[0002] The "limestone-gypsum" wet flue gas desulfurization process accounts for more than 80% of the existing desulfurization and environmental protection processes. Therefore, the wet flue gas desulfurization process is a relatively mature and widely used process. The desulfurization tower is the main structure of the wet flue gas desulfurization process. The desulfurization tower can convert sulfur dioxide in the flue gas into sulfate or sulfuric acid to purify the flue gas, thereby reducing sulfur emissions in the environment.

[0003] Multiple layers of support beams are arranged in the desulfurization tower. To save equipment cost, the support beams are generally made of carbon steel lined with glass flakes. Since the wet flue gas generated in the wet desulfurization process is highly corrosive, as the running time of the desulfurization tower increases, the scales of the support beams at individual points of the desulfurization tower will wear out. When the carbon steel of the support beam is in direct contact with the wet flue gas, the wet flue gas can rapidly corrode the support beam. After the surface of the support beam is corroded through, the wet flue gas and slurry can enter the inside of the support beam through this point. Since the inside of the support beam is a pure carbon steel structure, the support beam corrodes rapidly from the inside. In severe cases, the spray layer and the support beam in the tower will fall off, and the desulfurization tower will lose the supporting function of the support beam. In the mildest case, it will cause the components in the absorption tower to fall off, and the components will enter the slurry pump through the circulating slurry system, causing irreparable damage to the slurry pump and affecting the progress of the desulfurization operation. In severe cases, it will cause the desulfurization tower to collapse, resulting in production accidents and immeasurable losses to the enterprise. Utility Model Content

[0004] Aiming at the problem that the support beam currently used in the desulfurization tower has high potential safety hazard, the utility model provides a stabilizing device for the support beam of the desulfurization tower.

[0007] Preferably, a guide rail is fixedly mounted on the top of the bracket, a sliding block for sliding fit is mounted on the guide rail, and a rubber pad that is tightly connected to the bottom surface of the support plate is fixedly mounted on the sliding block.

[0008] Preferably, a first hinge seat and a second hinge seat are fixedly installed on both sides of the support plate, respectively, a top end of the first hinge arm is hinged to the first hinge seat, and a top end of the second hinge arm is hinged to the second hinge seat.

[0009] Preferably, a rotating shaft is provided in the bracket, the outer end of the rotating shaft is rotatably matched with the bracket, the inner end of the rotating shaft is rotatably matched with the receiving plate, and a limiting plate close to the receiving plate is fixedly installed on the outer wall of the inner end of the rotating shaft.

Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

A rotating shaft 13 is arranged inside the bracket 2, and the rotating shaft 13 is arranged horizontally inside the bracket 2. The outer end of the rotating shaft 13 is rotatably matched with the inner wall of the bracket 2, and the inner end of the rotating shaft 13 is rotatably installed with a receiving plate 6, and the outer side of the receiving plate 6 is provided with a limiting piece 14 installed on the outer wall of the inner end of the rotating shaft 13, and the limiting piece 14 is used to prevent the receiving plate 6 from slipping off the rotating shaft 13, thereby ensuring the stability of the connection between the receiving plate 6 and the rotating shaft 13.

[0023] The receiving plate 6 is a triangular plate structure, and the receiving plate 6 is provided with a top corner and two bottom corners; a first hinged arm 4 is hinged at the top corner of the receiving plate 6, a second hinged arm 5 is hinged at the corner of one end of the bottom of the receiving plate 6, and a telescopic cylinder 7 is hinged at the corner of the other end of the bottom of the receiving plate 6, and the piston rod of the telescopic cylinder 7 is hinged to the receiving plate 6.

[0024] The first articulated arm 4 and the second articulated arm 5 are each formed by two arms hinged to each other; the bottom arm of the first articulated arm 4 is hinged to the receiving plate 6, and the top arm end of the first articulated arm 4 is hinged to a first articulated seat 11; the bottom arm of the second articulated arm 5 is hinged to the receiving plate 6, and the top arm end of the second articulated arm 5 is hinged to a second articulated seat 12. The first articulated seat 11 and the second articulated seat 12 are both arranged at the top of the bracket 2.

[0025] A guide rail 8 is fixedly installed on the top of the bracket 2. Two guide rails 8 are symmetrically arranged. Each guide rail 8 is equipped with a slider 9 that can slide along the guide rail 8. A rubber pad 10 is fixedly installed on the slider 9. A support plate 3 is installed on the top of the two rubber pads 10. The bottom surface of the support plate 3 is tightly connected to the rubber pad 10. The support plate 3 can slide horizontally on the top of the bracket 2 under the cooperation of the slider 9, and the shock-absorbing structure of the rubber pad 10 can effectively improve the stability of the support plate 3. A plurality of mounting holes are opened on the support plate 3, which can be used to fasten the support plate 3 to the bottom of the desulfurization tower support beam, so that the device can be installed inside the desulfurization tower.

[0026] The first articulated seat 11 is fixedly installed on the left side of the support plate 3 by bolts, and the second articulated seat 12 is fixedly installed on the right side of the support plate 3 by bolts; when the support plate 3 slides along the guide rail 8, the structural form of the first articulated arm 4 and the second articulated arm 5 can be adjusted, so that the receiving plate 6 in the bracket 2 rotates along the inner end of the rotating shaft 13.

After the surface of the support beam is corroded by wet flue gas, the wet flue gas and slurry will enter the inside of the support beam, causing the inside of the support beam to corrode rapidly, and the support beam will be tilted after being unbalanced; when the support beam is tilted, the support beam will drive the support plate 3 to slide horizontally along the guide rail 8, so that the first articulated arm 4 and the second articulated arm 5 adjust the structural layout, and the first articulated arm 4 and the second articulated arm 5 will drive the receiving plate 6 to rotate along the rotating shaft 13. During the rotation of the receiving plate 6, the piston rod of the telescopic cylinder 7 can be extended outward, so that the air pressure in the inner cavity of the telescopic cylinder 7 changes; the operator can obtain the sliding stroke of the piston rod of the telescopic cylinder 7 through the pneumatic sensing equipment, and the operator can immediately obtain the imbalance state of the support beam, so as to ensure the timely maintenance of the support beam, thereby ensuring the normal operation of the desulfurization tower. In summary, the utility model has a very broad application prospect.
