This wet flue gas desulfurization absorption tower wall protector, absorption tower including the internally mounted nozzle, its characterized in that: the spray nozzle is arranged at the tail end of the slurry spraying pipeline, a pipe hoop is fixed at a position, close to the spray nozzle, of the slurry spraying pipeline, the pipe hoop is connected with a glass fiber reinforced plastic plate through an arc-shaped connecting steel plate, the glass fiber reinforced plastic plate is tightly attached to the inner wall of the absorption tower, and the position of the glass fiber reinforced plastic plate corresponds to a liquid outlet path of the spray nozzle. The utility model discloses under the condition that does not influence desulfurizing tower overall structure, adopt the protector of easily loading and unloading, prevented that edge nozzle spun thick liquid from directly scouring away to the tower wall, prevented the destruction of original interior anticorrosive coating, avoided the corruption of tower wall, the cost of maintenance of desulfurizing tower that has significantly reduced has increased desulfurization system's availability, has guaranteed the normal operating of production.
Description
(I) technical field
The utility model relates to an atmospheric environment protects technical field, in particular to wet flue gas desulfurization absorption tower wall protector.
(II) background of the invention
At present, the flue gas desulfurization processes adopted by coal-fired power stations in the world are various, and the flue gas desulfurization processes which are widely applied comprise: limestone-gypsum wet flue gas desulfurization, magnesium flue gas desulfurization, ammonia flue gas desulfurization, dry/semi-dry flue gas desulfurization and the like, wherein a wet flue gas desulfurization device accounts for about 85 percent, and is the most mature desulfurization process.
However, the process also has some disadvantages which are difficult to overcome, in particular the problem of scouring corrosion of the desulfurization absorption tower: the impact force of the slurry in the spraying area of the absorption tower is quite large, and the high-speed slurry continuously scours the tower wall, so that an anticorrosive coating in the tower wall is punctured or falls off, and the serious corrosion of the tower wall is formed.
Disclosure of the invention
The utility model discloses a remedy prior art not enough, provide a simple structure, be convenient for installation, excellent in use effect's wet flue gas desulfurization absorption tower wall protector.
The utility model discloses a realize through following technical scheme:
the utility model provides a wet flue gas desulfurization absorption tower wall protector, includes the absorption tower of internally mounted nozzle, its characterized in that: the spray nozzle is arranged at the tail end of the slurry spraying pipeline, a pipe hoop is fixed at a position, close to the spray nozzle, of the slurry spraying pipeline, the pipe hoop is connected with a glass fiber reinforced plastic plate through an arc-shaped connecting steel plate, the glass fiber reinforced plastic plate is tightly attached to the inner wall of the absorption tower, and the position of the glass fiber reinforced plastic plate corresponds to a liquid outlet path of the spray nozzle.
The utility model discloses a protection device of absorption tower wall is constituteed to the connection of ferrule, connecting plate and glass steel sheet, realizes the protecting against shock protection to the tower wall, increases the transmission path who sprays liquid simultaneously, improves and sprays desulfurization effect.
The utility model discloses a more excellent technical scheme does:
the connecting steel plate is connected with the pipe hoop in a welded mode, the glass fiber reinforced plastic plate is connected with the connecting steel plate in a bonded mode, the welding of the connecting steel plate ensures the connection strength of the pipe hoop and the glass fiber reinforced plastic plate, and meanwhile, the concrete installation position of the glass fiber reinforced plastic plate is convenient to adjust through a bonding mode.
The pipe hoop is made of 316L stainless steel, is convenient to disassemble, and meets the corrosion prevention requirement.
The connecting steel plate is made of 316L stainless steel or carbon steel coated with glass fiber reinforced plastic, so that the weight of the glass fiber reinforced plastic plate can be supported, and the corrosion prevention requirement can be met.
The glass fiber reinforced plastic plate is made of wear-resistant glass fiber reinforced plastic, is bonded with the connecting steel plate, is firm and reliable, and has no corrosion-resistant dead angle.
The thickness of the glass fiber reinforced plastic plate is 4-8mm and is tightly attached to the tower wall, a slurry film is formed at the tower wall through the rebound effect of the slurry, the phenomenon that the flue gas escapes along the tower wall is reduced, and the gas-liquid mass transfer effect is improved
The utility model adopts the protective device which is easy to assemble and disassemble without influencing the whole structure of the desulfurizing tower, prevents the direct scouring of the slurry sprayed by the edge nozzles to the tower wall, prevents the damage of the original inner anticorrosive coating, avoids the corrosion of the tower wall, greatly reduces the maintenance cost of the desulfurizing tower, increases the availability ratio of a desulfurizing system and ensures the normal operation of production; meanwhile, the fire in the tower is not needed in the installation process, and the method is safe, simple, convenient, effective and practical.
(IV) description of the drawings
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1 pipe hoop, 2 connecting steel plate and 3 glass steel plate.
(V) detailed description of the preferred embodiments
The attached drawing is a concrete embodiment of the utility model. The embodiment comprises an absorption tower internally provided with nozzles, wherein the nozzles are arranged at the tail end of a spraying slurry pipeline, a pipe hoop 1 is fixed at the position, close to the nozzles, of the spraying slurry pipeline, the pipe hoop 1 is connected with a glass fiber reinforced plastic plate 3 through an arc-shaped connecting steel plate 2, the glass fiber reinforced plastic plate 3 is tightly attached to the inner wall of the absorption tower, and the position of the glass fiber reinforced plastic plate 3 corresponds to a liquid outlet path of the nozzles.
Determining the position and the size of the glass steel plate 3 according to the position of a nozzle in the tower and the movement path of the sprayed slurry, thereby determining the size of the connecting steel plate 2; the size of the pipe clamp 1 is determined according to the size of the slurry pipe connected to the nozzle. Will outside the tower the utility model discloses protector is accomplished according to size processing, and the installer enters into installation protector in the tower to the actual conditions that the nozzle distributes in the tower adjusts. After the installation is accomplished, the start-up sprays, and is visible the utility model discloses the tower wall has been lived to the fine protection of protector, has avoided the direct impact of thick liquid, and glass steel plate 3 makes near tower wall formation thick liquid water film to the rebound effect of thick liquid simultaneously, can prevent effectively that the flue gas from hugging closely tower wall "escape".
Observe through long-term operation, the utility model discloses the protector effect is stable for desulfurization system's availability improves greatly, has reduced desulfurization system's interior anticorrosive maintenance cost, and practical effect is showing.
