Description

TECHNICAL FIELD

[0001] The application relates to the technical field of oil mist treatment equipment, in particular to an oil mist recovery system with a double-tower configuration. BACKGROUND

[0002] In the process of rolling aluminum foil, deformation heat is generated due to metal deformation, and rolling oil is used as a lubricating coolant to take away heat and reasonably lubricate. Due to the action of deformation heat, part of the rolling oil is atomized to form oil droplets with different particle sizes suspended above the rolling mill, which is commonly known as rolling oil mist. In engineering, oil droplets with a particle size greater than 5 microns are referred to as liquid oil mist, and oil droplets with a particle size less than 5 microns are referred to as gaseous oil mist. Oil mist will have a serious impact on the environment and human physical and mental health, so it is very important to collect and recycle oil mist during production.

[0003] Oil mist recovery has two main units, one for absorption and the other for desorption. The tower diameter of the absorption tower is determined by the system processing air volume. At present, the maximum processing capacity can reach 300,000 m 3 / h for a single unit. If the air volume is larger, two sets of oil mist recovery systems need to be configured, which will increase the investment cost, especially for cold rolling mills with low oil mist concentration in the exhaust smoke, the investment recovery period is longer. However, if the tower diameter of the absorption tower is enlarged to meet the exhaust smoke requirements, the packing height-to-tower diameter ratio in the tower will be out of balance, resulting in poor absorption effect. Therefore, an oil mist recovery system with a double-tower configuration is proposed to solve the above technical problems. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0021] In the following, the present application is further described in conjunction with specific embodiments, and it should be noted that the following described embodiments or technical features can be combined in any manner to form new embodiments without conflict.

[0022] In the description of the present application, it should be noted that for orientation words, such as terms "center", "transverse", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate the orientation and positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0024] One of the preferred embodiments of the present application is, for example, Figures 1 to 5As shown, an oil mist recovery system of a double-tower configuration includes a desorption tower 1, a pair of absorption towers 2, and a pump body 3, wherein the air inlet ends of the two groups of absorption towers 2 are connected with the oil mist absorption equipment, the oil outlet end of the absorption tower 2 is connected with the input end of the pump body 3, and the output end of the pump body 3 is connected with the oil inlet end of the desorption tower 1. Of course, the desorption tower 1, the absorption tower 2, the pump body 3, and how the pump body 3 transports the oil in the absorption tower 2 to the desorption tower 1 through the pipeline are all common knowledge of those skilled in the art.

[0025] It should be known that the oil mist recovery system mainly includes absorption and desorption stages during operation, wherein the absorption is to dissolve and absorb the rolling oil mist in the flue gas by the absorbent, the desorption is to separate the rolling oil and the absorbent dissolved in the absorbent by means of pressure reduction distillation, the oil-containing flue gas generated by the rolling mill is extracted from the rolling mill exhaust hood by the fan and then transported to the absorption tower 2 for absorption, that is, the flue gas is absorbed by the oil mist absorption equipment and transported into the absorption tower 2. That is, the existing smoke recovery system is mainly matched by one absorption tower 2 plus one desorption tower 1, and when the air volume increases, one absorption tower 2 cannot meet the demand, so two sets of oil mist recovery systems are needed, which increases the cost.

[0026] Therefore, in the present application, a pair of absorption towers 2 and a desorption tower 1 are matched to form a double (absorption) tower oil mist recovery system, so that when the air volume of the oil mist extraction increases, the two absorption towers 2 can meet the oil mist absorption treatment operation, thereby avoiding the cost problem of needing to configure two sets of systems due to excessive air volume, that is, the cost can be effectively controlled under the premise of normal operation of large air volume.

[0027] The existing absorption tower 2 uniformly sprays the introduced absorbent through the atomizing nozzle 401 during work, since the atomizing nozzle 401 is located at the central position of the spraying working chamber, and the maintenance opening 201 for maintaining the atomizing nozzle 401 is located at the side position of the absorption tower 2, so there is a certain distance between the atomizing nozzle 401 and the maintenance opening 201, which makes it inconvenient for the maintenance personnel to manually maintain or replace the atomizing nozzle 401, and the way of using the maintenance tool to enter the spraying working chamber from the maintenance opening 201 and implement the maintenance operation is relatively cumbersome, and the whole maintenance or replacement operation is difficult. Of course, in order to improve the atomization effect of the atomizing nozzle 401, the atomizing nozzle 401 can be composed of multiple nozzles, that is, multiple nozzles are arranged in multiple directions, so that the absorbent can be uniformly sprayed in the absorption tower 2, thereby ensuring that the gas oil mist passing through can be fully absorbed, thereby improving the oil mist recovery efficiency.

[0028] Therefore, in order to solve the above technical problems, in one embodiment of the present application, as shown in Figure 2As shown, the outer upper end of the absorption tower 2 is provided with an access opening 201, and the inner upper center of the absorption tower 2 is provided with an atomization assembly 4 corresponding to the access opening 201. The atomization assembly 4 includes an atomization pipe 402 and an atomization nozzle 401. The atomization pipe 402 is horizontally installed through the absorption tower 2. The atomization nozzle 401 is installed at the end of the atomization pipe 402 through a connecting structure 5. The atomization nozzle 401 is located at the inner upper center of the absorption tower 2. The outer part of the atomization nozzle 401 is provided with an operating rod 6, which extends to the access opening 201.

[0029] It can be understood that when the staff needs to overhaul the atomization nozzle 401, the door of the access opening 201 is first opened, and then the staff holds the operating rod 6 to disassemble and assemble the atomization nozzle 401 through the cooperation of the operating rod 6 and the connecting structure 5. In this way, the staff does not need to enter the tower body to operate, thereby simplifying the overhaul process and improving the overhaul efficiency.

[0030] Of course, the connecting structure 5 has various structural forms, including but not limited to the following two structures:

[0031] Structure one (not shown): The connecting structure 5 includes a connecting pipe 501. The first end of the connecting pipe 501 is detachably installed (for example, bolted) on the atomization nozzle 401. The second end of the connecting pipe 501 is threadedly connected with the end of the atomization pipe 402. The operating rod 6 is fixedly installed on the connecting pipe 501 and coaxially arranged with the second end of the connecting pipe 501.

[0032] It can be understood that when the staff disassembles the atomization nozzle 401, the connecting pipe 501 can be rotated in the opposite direction through the operating rod 6, so that the connecting pipe 501 is screwed and separated from the atomization pipe 402. Finally, the atomization nozzle 401 can be taken out of the access opening 201 through the operating rod 6. Similarly, when the atomization nozzle 401 is installed, the atomization nozzle 401 is first inserted into the tower body through the operating rod 6, and the connecting pipe 501 is connected with the atomization pipe 402. Then, the connecting pipe 501 is driven to rotate in the forward direction through the operating rod 6, so that the connecting pipe 501 is screwed and connected with the atomization pipe 402, thereby achieving the installation of the atomization nozzle 401.

[0033] Structure two: as shown in Figure 2 and Figure 3 The connecting structure 5 includes a connecting pipe 501, a connecting sleeve 502, and a transmission assembly 503. The first end of the connecting pipe 501 is detachably installed (for example, bolted) on the atomization nozzle 401. The second end of the connecting pipe 501 is rotationally connected with the connecting sleeve 502. The connecting sleeve 502 is threadedly connected with the end of the atomization pipe 402. The transmission assembly 503 is installed on the connecting pipe 501. The input end of the transmission assembly 503 is connected with the operating rod 6. The output end of the transmission assembly 503 is connected with the connecting sleeve 502.

[0034] It can be understood that when the atomizing nozzle 401 is disassembled, it is actually the butt joint relationship between the connecting sleeve 502 and the atomizing pipe 402. Therefore, when the staff disassembles and assembles the atomizing nozzle 401, the operating rod 6 can be operated at this time, and the operating rod 6 drives the connecting sleeve 502 to rotate through the transmission assembly 503. For example, the forward helical rotation of the connecting sleeve 502 can be matched with the atomizing pipe 402, that is, the installation of the atomizing nozzle 401 can be realized, as shown in (a) of Figure 3 ; the reverse helical rotation of the connecting sleeve 502 can be matched with the atomizing pipe 402, that is, the disassembly of the atomizing nozzle 401 can be realized, as shown in (b) of Figure 3 .

[0035] The specific structure of the transmission assembly 503 is not limited in the present application, and a specific structure is provided below for reference:

[0036] As shown in Figure 4 , the operating rod 6 is rotatably installed on the connecting pipe 501, the transmission assembly 503 includes a gear ring 5031 and a gear 5032, the gear ring 5031 is sleeved and installed on the connecting sleeve 502, and the gear 5032 is installed on the operating rod 6.

[0037] It can be understood that the staff drives the gear 5032 to rotate through the operating rod 6, and the gear 5032 acts on the gear ring 5031, so that the gear ring 5031 drives the connecting sleeve 502 to rotate, and the threaded engagement and separation between the connecting sleeve 502 and the atomizing pipe 402 are realized, thereby realizing the disassembly and assembly of the atomizing nozzle 401.

[0038] Further, as shown in Figure 4 , the connecting pipe 501 includes a horizontal section 5011 and a vertical section 5012 (that is, the connecting pipe 501 has an L-shaped structure) which are in communication with each other, the horizontal section 5011 is connected with the connecting sleeve 502, and the vertical section 5012 is connected with the atomizing nozzle 401. The operating rod 6 penetrates and is rotatably installed in the vertical section 5012, that is, the vertical section 5012 has two supporting points for the operating rod 6, thereby making the installation stability of the operating rod 6 better.

[0039] Based on the above embodiment, another embodiment of the present application is that the atomizing pipe 402 and the connecting pipe 501 can be matched through the positioning assembly 7. It can be understood that when the atomizing nozzle 401 is disassembled, the connecting pipe 501 and the atomizing pipe 402 are guided and positioned through the positioning assembly 7, so that the atomizing nozzle 401 does not shake during disassembly, thereby being more convenient to operate.

[0040] Specifically, as shown in Figure 3As shown, the positioning assembly 7 comprises a positioning rod 701 and a positioning plate 702, the positioning plate 702 is installed on the atomizing pipe 402 and externally provided with a positioning groove 703, and the positioning rod 701 is installed on the connecting pipe 501 and matched with the positioning groove 703. It can be understood that when installing, the worker can correspond and insert the positioning rod 701 into the positioning groove 703 through the operation rod 6, and then butt the connecting sleeve 502 with the atomizing pipe 402 through the operation rod 6, so that the connecting sleeve 502 will not rotate along the axial direction when the operation rod 6 rotates subsequently, and can also support the atomizing nozzle 401, so that the operation rod 6 is more convenient to rotate, and the atomizing nozzle 401 can also maintain the correct installation position of being vertically downward after installation. Similarly, when disassembling, when the connecting sleeve 502 is separated from the atomizing pipe 402 by rotating the operation rod 6, if there is no limiting effect of the positioning rod 701 and the positioning groove 703, the atomizing nozzle 401 will have a sudden downward force under gravity at the moment of separation, and then the phenomenon of slipping off may occur, which is not convenient to operate.

[0041] Finally, it should be pointed out that when structure one is adopted, although the structure is simple, the whole atomizing nozzle 401 needs to be rotated together through the operation rod 6 when operating, which makes disassembly more laborious, and after installation, the atomizing nozzle 401 may not necessarily maintain a correct vertically downward state, therefore structure two is preferred; of course, both structures can meet the actual needs, and those skilled in the art can select according to the actual situation.

[0042] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, the above embodiments and descriptions in the specification are only the principles of the present application, and various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
