Description

Technical Field

[0001] The utility model relates to a filter element cleaning device. Background Art

[0002] During the battery preparation process, waste gas containing VOCs is generated. The waste gas is treated through an activated carbon fiber filter. An adsorption core is used in the activated carbon fiber filter. The adsorption core continuously adsorbs VOCs. Under high-intensity operation, the impurities contained in the adsorption core increase, the mechanical strength decreases, and the adsorption efficiency decreases, which greatly affects the qualified emission of exhaust gas and is not conducive to the recovery of effective components in the waste gas by the adsorption core. At this time, the waste adsorption core will be taken out and replaced with a new one. This operation has a high replacement frequency and high cost for waste solid treatment of the adsorption core.

[0003] In the process of using activated carbon fiber to adsorb VOCs in exhaust gas, it was found that the performance of the activated carbon fiber was attenuated. Through fiber inspection and testing, it was found that the steam containing sulfate and steam containing water were the main factors of fiber attenuation. This impurity component could not be removed in the subsequent desorption process. Utility Model Content

The fixing frame 1 is used to fix the filter element 4 to be cleaned. The fixing frame 1 includes a bottom frame and a plurality of columns 13. The plurality of columns 13 are connected to the bottom frame to form an accommodating space for accommodating the filter element 4 to be cleaned. A support member is disposed in the accommodating space. The support member is disposed on the fixing frame 1 and connected to the fixing frame 1. There is a space between the support member and the bottom frame for one end of the filter element 4 to pass through. The support member is used to support the filter element 4 to be cleaned. The cleaning tank 2 has a cavity that can accommodate the fixing frame 1; a liquid inlet 212 and a liquid outlet 211 are provided on the cleaning tank 2.

[0043] The device has a cleaning state. When in the cleaning state, the filter element 4 to be cleaned is placed on the fixing frame 1, and the fixing frame 1 is located in the cavity of the cleaning tank 2. Cleaning liquid is conveyed into the cavity through the liquid inlet 212 of the cleaning tank 2. After a preset cleaning time, the liquid in the cleaning tank 2 is discharged, the fixing frame 1 is taken out, and then the filter element 4 is dried. The filter element 4 can be used again.

[0048] The support member includes a first support member and a second support member. There is a gap between the first support member and the second support member. The structures of the first support member and the second support member are the same. The first support member and the second support member are symmetrically arranged. Both the first support member and the second support member are in an inverted U - shape, which is a straight U - shape. The first support member and the second support member are distributed in the front - back direction ( Figure 7 ), or the first support member and the second support member are distributed in the left - right direction ( Figure 4 ). There is a gap between the first support member and the second support member for the middle filter cartridge of the filter element 4 to pass through. When the filter element 4 to be cleaned is placed in the fixing frame 1 and the fixing frame 1 is vertically arranged (that is, the vertical beam 17 is in the vertical direction), the bottom of the filter screen of the filter element 4 abuts against the upper surfaces of the first support member and the second support member, and one end of the central cylinder of the filter element 4 extends into the gap between the support member and the chassis.

[0049] In one embodiment, both the first support member and the second support member are in an inverted U - shape, which is a straight U - shape. The inverted U - shape means the opening is downward. Both the first support member and the second support member include a longitudinal beam 16 and two vertical beams 17. The two vertical beams 17 of the first support member are distributed in the front - back direction and are connected to the crossbar 11 of the chassis. The opposite ends of the longitudinal beam 16 of the first support member are respectively connected to the two vertical beams 17 of the first support member; the two vertical beams 17 of the second support member are distributed in the front - back direction and are connected to the crossbar 11 of the chassis.

The longitudinal beam 16 is parallel to the longitudinal bar 12 of the chassis, and the vertical beam 17 is parallel to the vertical column.

[0050] In the above - mentioned embodiment, further, referring to Figures 4 - 6 , both the first support member and the second support member further include two first connecting beams 18. The first connecting beam 18 and the longitudinal beam 16 are in the same horizontal plane. The first connecting beam 18 and the longitudinal beam 16 are perpendicularly arranged. The two first connecting beams 18 of the first support member are distributed in the front - back direction. One end of each of the two first connecting beams 18 of the first support member is respectively connected to the two vertical columns 13, and the other end is respectively connected to the two ends of the longitudinal beam 16. One end of each of the two first connecting beams 18 of the second support member is respectively connected to the other two vertical columns 13, and the other end is respectively connected to the two ends of the longitudinal beam 16.

[0051] In another embodiment, both the first support member and the second support member are in an inverted U shape, where the inverted U shape means the opening faces downward. Both the first support member and the second support member include a cross beam 15 and two vertical beams 10. The two vertical beams 10 of the first support member are distributed in the left-right direction and are connected to the longitudinal bars 12 of the chassis. The opposite ends of the cross beam 15 of the first support member are respectively connected to the two vertical beams 10 of the first support member; the two vertical beams 10 of the second support member are distributed in the left-right direction and are connected to the longitudinal bars 12 of the chassis. The opposite ends of the cross beam 15 of the second support member are respectively connected to the two vertical beams 10 of the first support member. The cross beam 15 is parallel to the cross bar 11 of the chassis, the first connecting beam 18 is parallel to the longitudinal bar 12 of the chassis, and the vertical beam 10 is parallel to the vertical column. When the filter element 4 is placed in the fixing frame, the bottom of the filter screen of the filter element 4 abuts against the cross beam 15.

[0052] In the above embodiment, further, referring to Figures 7 - 9 , both the first support member and the second support member further include two second connecting beams 19. The two second connecting beams 19 are distributed in the left-right direction. The second connecting beam 19 and the cross beam 15 are located in the same horizontal plane. One end of each of the two second connecting beams 19 of the first support member is respectively connected to the two vertical columns 13 distributed in the left-right direction, and the other end of each of the two second connecting beams 19 of the first support member is respectively connected to the two vertical beams 10 (or the two ends of the cross beam 15) of the first support member; the opposite ends of the cross beam 15 of the second support member are respectively connected to the two vertical beams 10 of the first support member. One end of each of the two second connecting beams 19 of the second support member is respectively connected to the other two vertical columns 13 distributed in the left-right direction, and the other end of each of the two second connecting beams 19 of the second support member is respectively connected to the two vertical beams 10 (or the two ends of the cross beam 15) of the second support member. The cross beam 15 is parallel to the cross bar 11 of the chassis, the second connecting beam 19 is parallel to the longitudinal bar 12 of the chassis, and the vertical beam 10 is parallel to the vertical column.

[0053] In the cleaning state, if the cross beam 15 extends in the left-right direction, the longitudinal beam 16 extends in the front-back direction, and the vertical beam 17 and the vertical beam 10 both extend in the vertical direction. When the filter element 4 to be cleaned is placed in the fixing frame 1 and the fixing frame 1 is vertically arranged (i.e., the vertical beam 17 extends in the vertical direction), the bottom of the filter screen of the filter element 4 abuts against the longitudinal beam 16, and one end of the central cylinder of the filter element 4 extends into the gap between the support member and the chassis.

[0054] When there are multiple accommodating spaces in the accommodating space of the fixing frame 1, a gap is maintained between adjacent two accommodating spaces. A connecting rod 20 is arranged in the gap. The connecting rod 20 is located between adjacent two vertical columns 13. Both ends of the connecting rod 20 are respectively connected to these two vertical columns 13. The connecting rod 20 plays a strengthening role, making the overall structure more stable. In some embodiments, the connecting rod 20 is perpendicular to the vertical column 13, or the connecting rod 20 is inclined; multiple connecting rods 20 can be arranged. The multiple connecting rods 20 are sequentially distributed in the height direction of the fixing frame 1, and the multiple connecting rods 20 can be arranged in parallel.

[0055] In some embodiments, the fixing frame 1 further includes a limiting rod 14. Refer to Figure 5 , 8 . The limiting rod 14 is detachably arranged between two adjacent columns 13. The limiting rod 14 can be perpendicular to the column 13, or the limiting rod 14 is inclined. For two adjacent columns 13, when the limiting rod 14 is located between these two columns 13, the two columns 13 and the limiting rod 14 form one side of the fixing frame 1, and the limiting rod 14 forms a block on this side. When the filter element 4 to be cleaned is placed in the fixing frame 1, the limiting rod 14 can limit the filter element 4 to be cleaned from detaching from this side of the fixing frame 1. Preferably, a limiting rod 14 is arranged between every two adjacent columns 13, and blocks can be formed on the four sides (front side, rear side, left side, right side) of the fixing frame 1, which can better limit the filter element 4 to be cleaned from detaching from the accommodating space of the fixing frame 1.

[0056] In this example, the detachable embodiment of the limiting rod 14 is as follows: a through hole 131 for the limiting rod 14 to pass through is formed on the column 13. A limiting rod 14 is located between two adjacent columns 13. After the filter element 4 is placed in the fixing frame 1, the limiting rod 14 is then passed through the through hole 131 of the column 13, and the opposite ends of the limiting rod 14 are respectively located in the through holes 131 of the two adjacent columns 13. When it is not needed, the limiting rod 14 can be pulled out, and the operation is simple and convenient.

[0057] Refer to Figure 10 . A lifting lug 3 is arranged on the upper side of the fixing frame 1, which is convenient for the lifting mechanism to cooperate with the lifting lug 3 to transfer the fixing frame 1 into the cleaning tank 2. An opening is formed on the lifting lug 3, and the lifting lug 3 can be in a U shape.

[0058] In this example, the cavity of the cleaning tank 2 is separated into a first cavity 21 and a second cavity 22 by a partition 23. The second cavity 22 is located below the first cavity 21. When in the cleaning state, a gap is maintained between the filter element 4 to be cleaned and the partition 23. A liquid inlet 212 and a liquid outlet 211 are formed on the first cavity 21, and the setting position of the liquid inlet 212 is higher than the setting position of the liquid outlet 211. A liquid outlet 221 is formed on the second cavity 22, the setting position of the liquid outlet 211 is higher than the liquid outlet 221, and the liquid outlet 221 and the liquid outlet 211 are communicated through a pipeline, and the pipeline is located in the second cavity 22. The arrangement of the second cavity 22 is convenient for arranging the liquid outlet pipeline and facilitating the complete discharge of the liquid in the cleaning tank 2 from the liquid outlet 221.

[0059] In some embodiments, the liquid outlet 211 and the liquid outlet 221 are respectively on the opposite sides of the cleaning tank 2. The arrangement of the two outlets is convenient for completely discharging the liquid in the cleaning tank 2 from the two outlets.

[0060] In some embodiments, a reinforcing rod 24 is disposed in the second cavity 22, and the reinforcing rod 24 extends in the vertical direction. The cleaning tank 2 in this example is cube-shaped, and the cleaning tank 2 has an upper side and a lower side that are oppositely arranged up and down, a front side and a rear side that are oppositely arranged front and back, and a left side and a right side that are oppositely arranged left and right. The side surface of the cleaning tank 2 is preferably made of 304 stainless steel plate. A reinforcing rib 25 is provided on the outer periphery of the cleaning tank 2 in this example to increase the strength of the cleaning tank 2.

[0061] The specific implementation manner of the filter element cleaning device in this example for cleaning the filter element is as follows:

[0062] 1. First, lay the filter element and the fixing frame flat (both the center line of the filter element and the columns of the fixing frame are horizontally arranged), roll the filter element into the inside of the fixing frame, place the filter element connection flange above the position of the support member. After the position is confirmed, connect the limiting rod between two adjacent columns to fix the filter element; then slowly lift the filter element and the fixing frame vertically by hoisting the lifting lugs on the fixing frame, and hoist the filter element and the fixing frame into the cleaning tank and place them stably; when placing the filter element on the fixing frame, the filter element is inverted, which is beneficial to the smooth discharge of the contaminants attached to the filter element;

[0063] 2. Drain hot water (the hot water used is preferably 60 - 70 °C) from the liquid inlet of the cleaning tank, and the water level is higher than the highest point of the filter element. After cleaning for a period of time, the water in the cleaning tank will be relatively turbid for the first time. Keep the water temperature and water level for 30 minutes, and then directly discharge the water in the cleaning tank through the liquid outlet and the liquid discharge port;

[0064] 3. Enter the second water wash. Similarly, drain hot water so that the water level is higher than the highest point of the filter element, and then connect a beaker of the sewage in the tank every 5 minutes through the liquid discharge port. Then observe the color of the beaker through the white-lined paper until the color of the new beaker of sewage no longer visibly darkens significantly compared with the color of the previous beaker. Keep the water temperature and water level for 30 minutes, and then directly discharge the water in the tank through the liquid discharge port and the liquid outlet;

[0065] 4. Re-drain hot water and repeat the above steps about 2 - 3 times until the hot water in the new tank remains clear and then stop the operation. Keep the water temperature and water level for 30 minutes, and then directly discharge the water in the tank through the liquid discharge port and the liquid outlet on the cleaning tank;

[0066] 5. Lift out the filter element and the fixing frame, dry the cleaned filter element, and the cleaning process ends.

[0067] When cleaning a new filter element to be cleaned, the above steps can be repeated, and the operation is simple.

[0068] The advantages of the filter element cleaning device in this example are:

[0069] Through the hot water cleaning method in the cleaning tank, the activated carbon adsorption filter element is repeatedly cleaned and then naturally dried. The hot water cleaning method does not damage the mechanical strength, chemical properties, and physical properties of the activated carbon adsorption filter element, and enhances the adsorption effect of the activated carbon adsorption filter element, with low cost and high economic value. After the activated carbon adsorption filter element is cleaned, it is equivalent to being recycled once, its service life is extended, the replacement frequency decreases, and the cost is reduced; after the activated carbon adsorption filter element is added to the adsorption tank again, the adsorption efficiency is enhanced, and the tail gas VOCs content meets the standards.

[0070] The above embodiments are only for illustrating the technical concept and characteristics of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
