Description

Technical Field

[0001] The utility model relates to the technical field of iron oxide production, in particular to an acid mist spray tower for iron oxide production. Background Art

[0002] During the production process of iron oxide, a large amount of acid mist will be generated. In order to purify this acid mist, an acid mist spray tower is usually used. However, there are some problems in the actual application of the existing acid mist spray tower for iron oxide production.

[0003] On the one hand, when the water pump in the spray tower pumps the medicament for spraying, due to the lack of effective filtering measures, it is very easy to suck in impurities, resulting in the blockage of the water pump. Once the water pump is blocked, the entire spray system will stop running, seriously affecting the efficiency and effect of acid mist purification.

[0004] On the other hand, even if some spray towers are equipped with filtering devices, during long-term use, a large amount of impurities are easily attached to the filter screen, or crystallization occurs due to the action of the medicament. These impurities and crystals will gradually block the filter screen, reducing the filtering effect, and at the same time increasing the maintenance cost and workload of the system. Moreover, when the filter screen is severely blocked, it may also affect the normal operation of the water pump and even cause damage to the water pump.

[0005] In summary, the existing acid mist spray tower for iron oxide production has relatively large defects in impurity treatment and urgently needs to be improved. Content of the Utility Model

Detailed implementation manners

[0026] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0027] Such as Figures 1 - 9As shown in the figure, a mist spray tower for iron oxide production proposed by the utility model has a chemical replenishment water tank 11 provided at the bottom on one side of the spray tower body 10 in the acid mist purification assembly 1. One side of the chemical replenishment water tank 11 is located inside the spray tower body 10, and a filter screen 12 is installed on the end face of this side. An inverted "L"-shaped fixing plate 15 on the top of the chemical replenishment water tank 11 is movably provided with a lead screw 26 through a bearing seat 21. The bottom end of the lead screw 26 is movably provided on the bottom plate of the spray tower body 10 through a sealed bearing 22 and is connected to the transmission end of a motor 20 in the mounting frame 13. A driving member 24 is threadedly driven on the lead screw 26. There are several rows of bristles 25 on the front of the brush plate 23 on the driving member 24, and the bristles 25 are attached to the surface of the filter screen 12, forming an anti-blocking assembly 2. A spray assembly 3 is also provided on the top of the chemical replenishment water tank 11. The water pumping end of a water pump 30 in this assembly is connected to a suction pipe 33, and the other end of the suction pipe 33 is located inside the chemical replenishment water tank 11. The water outlet end of the water pump 30 is connected to a three-way pipe 31, and spray pipes 32 are respectively connected to the other two ports of the three-way pipe 31. The spray pipes 32 are located inside the spray tower body 10;

[0028] An air inlet 14 and a cleaning port 16 are provided on one side of the spray tower body 10. A sealing door 18 is connected to the side of the cleaning port 16 through a hinge 17. An air outlet 110 is provided on the top of the spray tower body 10. One end of a first air duct 40 in the air extraction assembly 4 is connected to the air outlet 110, and the other end of the first air duct 40 is connected to the air inlet end of an air extractor 41. The air outlet end of the air extractor 41 is connected to a second air duct 42. A rain shield 43 is provided on the top of the second air duct 42. A detachable activated carbon adsorption plate 19 is provided on one side of the spray tower body 10, above the spray pipes 32.

[0029] During use, first pour the neutralization and purification chemical into the chemical replenishment water tank 11, and then turn on the water pump 30. At this time, the water pump 30 will continuously pump out the chemical in the chemical replenishment water tank 11 and transport it to the two spray pipes 32. Subsequently, the chemical sprays out and falls from the spray pipes 32. Then, accurately connect the exhaust port of the iron oxide production equipment to the air inlet 14 of this device, and then turn on the air extractor 41 and the motor 20 simultaneously;

[0030] After the air extractor 41 is started, a strong suction force will be generated to extract the acid mist from the iron oxide production equipment. Under the action of the air extractor 41, the acid mist enters the spray tower from the air inlet 14 and starts to move upward. During this process, the acid mist comes into full contact with the falling chemical and undergoes a neutralization and purification reaction. The gas after neutralization and purification continues to rise and passes through the activated carbon adsorption plate 19. The activated carbon adsorption plate 19 will secondarily filter and adsorb some impurities in the gas during this process. Finally, the purified gas passes through the first air duct 40 and is discharged from the top of the second air duct 42;

[0031] When the motor 20 starts up, it should be set to the reciprocating cycle forward and reverse mode. When the motor 20 rotates, it will drive the driving member 24 through the lead screw 26, and then the driving member 24 drives the brush plate 23 to move up and down. In this way, the brush plate 23 can reciprocally brush the filter screen 12, effectively avoiding the blockage of the filter holes by impurities in the medicament, and at the same time preventing the crystallization of special impurities on the filter screen 12 to cause blockage, ensuring the normal operation of the entire device and good filtering effect.

[0032] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
