Description
Technical Field
The utility model relates to a limestone-gypsum wet desulfurization equipment field, especially a desulfurizing tower flue gas cooling structure.
Background
The waste flue gas generated in the pellet production process can be discharged after reaching the standard through desulfurization treatment. And the import temperature before the useless flue gas enters the desulfurization is about 120 ℃, and has glass scale anticorrosive coating and defroster in the desulfurizing tower, and glass scale anticorrosive coating and defroster do not all bear the high temperature more than 80 ℃, otherwise can cause anticorrosive coating to destroy and the defroster warp to influence desulfurization system normal operating. Therefore, the temperature of the flue gas needs to be lowered in advance, so that the glass flake anticorrosive coating and the demister are protected.
However, the existing spraying device has the defects that the spray pipe is unreasonable in design, the spray head of the spraying device is small in water spraying amount and easy to block, and once the spraying device is blocked, the spraying device is inconvenient to replace and often cannot effectively control the falling of an anticorrosive coating and the deformation of a demister due to too high flue gas temperature.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a convenient efficient change shower nozzle when the shower nozzle appears blocking is provided to guarantee the smooth desulfurizing tower flue gas cooling structure that goes on of flue gas cooling.
The utility model provides a technical scheme that its technical problem adopted is: desulfurizing tower flue gas cooling structure, including desulfurizing tower entry pipeline and set up in the cooling water pipe of the outer wall of desulfurizing tower entry pipeline, including at least one shower device, the shower device passes desulfurizing tower entry pipeline wall and sets up in desulfurizing tower entry pipeline, cooling water pipe and shower device intercommunication, wherein, be detachable connection structure between the shower nozzle of shower device and the shower device.
Furthermore, the detachable connecting structure between the spray head and the spray pipe device is a detachable flange connecting structure.
Furthermore, the wall surface of the spray head is uniformly provided with through holes.
Further, the diameter of the through hole is
Furthermore, the spray pipe devices are divided into three groups, and cooling water pipes penetrate through the wall surface of the inlet pipeline of the desulfurization tower and are communicated with the three groups of spray pipe devices.
Further, seven spray heads are provided for each shower unit.
Further, the material of the spray head is stainless steel.
Further, the shower pipe device is fixed to the inlet pipe of the desulfurization tower by bolts.
The utility model has the advantages that: in actual use, cooling water flows to the spray pipe device through the cooling water pipe and is sprayed out through a spray head of the spray pipe device to realize cooling. In case the condition of shower nozzle beiblockked up need dismantle when changing, only need take out the shower device to the outer wall orientation of desulfurizing tower inlet pipeline, can take out the shower nozzle of shower device outside the desulfurizing tower inlet pipeline in the lump to convenient the shower nozzle of dismantling realizes changing, the shower device after the change then passes desulfurizing tower inlet pipeline wall once more and sets up in the desulfurizing tower inlet pipeline, and realize the cooling once more. The utility model is particularly suitable for cooling the flue gas of a limestone-gypsum wet-type desulfurizing tower.
Drawings

Fig. 2 is a side view of the present invention.
Labeled as: desulfurizing tower 1, desulfurizing tower inlet pipeline 2, cooling water pipe 3, shower device 4, bolt 41, shower nozzle 5, through-hole 51.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, fig. 2, the cooling structure for flue gas of desulfurizing tower includes desulfurizing tower inlet pipe 2 and cooling water pipe 3 arranged on the outer wall surface of desulfurizing tower inlet pipe 2, including at least one spray pipe device 4, spray pipe device 4 passes desulfurizing tower inlet pipe 2 wall surface and sets up in desulfurizing tower inlet pipe 2, and cooling water pipe 3 and spray pipe device 4 communicate, wherein, be detachable connection structure between spray head 5 of spray pipe device 4 and spray pipe device 4.
Because shower device 4 passes 2 walls of desulfurizing tower entry pipeline and sets up in desulfurizing tower entry pipeline 2, also for follow-up 5 with shower device 4 and shower device 4 take out from desulfurizing tower entry pipeline 2 in provide the basis of structure, thereby realize dismantling and changing of shower nozzle 5 in desulfurizing tower entry pipeline 2 outside, reduced the degree of difficulty of the change that traditional structure brought. As a method for realizing the detachable connection structure between the spray head 5 of the spray pipe device 4 and the spray pipe device 4, it is preferable that the detachable connection structure between the spray head 5 and the spray pipe device 4 is a detachable flange connection structure. In order to ensure the durability of the spray head in use, the material of the spray head 5 is stainless steel. In order to facilitate the stable arrangement of the shower device 4 on the inlet pipe 2 of the desulfurization tower and the subsequent convenient disassembly, it is preferable that the shower device 4 is fixed on the inlet pipe 2 of the desulfurization tower by a bolt 41.
In order to further increase the amount of water sprayed and at the same time reduce the possibility of clogging of the spray head 5, it is preferable to adopt: through holes 51 are uniformly formed in the wall surface of the nozzle 5. The through holes 51 can not only increase the water spraying amount and further strengthen the cooling effect, but also can greatly prolong the time of completely blocking the spray head 5, thereby effectively ensuring the smooth production. In combination with practical experience, it is preferable that the diameter of the through hole 51 is
In order to ensure that the shower arrangement 4 can provide sufficient cooling water, the option of: the spray pipe devices 4 are three groups, and the cooling water pipe 3 penetrates through the wall surface of the inlet pipeline 2 of the desulfurizing tower and is communicated with the three groups of spray pipe devices 4. Like figure 1 three groups of shower devices 4 can provide a large amount of cooling water simultaneously to strengthen the cooling effect to the flue gas, glass scale anticorrosive coating and the defroster in the better protection desulfurizing tower. Based on the same concept, seven spray heads 5 are preferably provided per shower unit 4.
