DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0030] Please refer to Figures 1-10 ​The application provides the technical scheme: a fermentation waste gas treatment equipment, comprising a tower body 1, three leakage plates 2 are arranged in the tower body 1 at intervals, a filler assembly 3 is arranged between the leakage plates 2, the filler assembly 3 comprises four mounting plates 31, a plurality of intermediate rods 32 are arranged between the mounting plates 31, a corrugated plate one 33 is connected to the lower side of the intermediate rod 32, an elastic plate group is connected to the upper side of the intermediate rod 32, the elastic plate group comprises a fixed outer plate 341, one side of the fixed outer plate 341 is connected and fixed with the intermediate rod 32, a movable plate 342 is slidably arranged on the surface of the side of the fixed outer plate 341 facing the intermediate rod 32, a fixing piece 343 is connected to the other side of the movable plate 342, a plurality of elastic blocks 344 are connected to the fixing piece 343 at intervals, a cover 345 is fixed to the intermediate rod 32 in cooperation with the elastic blocks 344, the elastic blocks 344 and the cover 345 are in sliding fit, an expansion spring 346 is connected between the intermediate rod 32 and the elastic blocks 344, a pressure sensing module 35 is arranged on the upper side of the movable plate 342, and a brush 36 is connected to the pressure sensing module 35.

[0031] Further, as shown in the figure, Figure 4 The cover 345 is laid with an electromagnetic module at the bottom, and the lower surface of the elastic block 344 is laid with an adsorbable material layer.

[0032] The supplementary description based on the above structure is as follows: a plurality of leakage holes 21 are formed in the leakage plate 2, the fixed outer plate 341 and the movable plate 342 are arranged in a corrugated plate structure, and the fixing piece 343 is arranged on the surface of the movable plate 342. Preferably, a limiting sleeve is connected to the upper side of the fixed outer plate 341 in cooperation with the movable plate 342, for guiding the longitudinal movement of the movable plate 342 and avoiding the deviation of the movable plate 342 in other directions when sliding. When the electromagnetic module is in a power-off state, the movable plate 342 is affected by the expansion spring 346, at this time, the distance between the bottom of the movable plate 342 and the intermediate rod 32 is maximum, and the brush 36 can contact the leakage hole 21. When the electromagnetic module is in a power-on state, the adsorbable material layer is attracted, driving the elastic block 344 to slide downward in the cover 345, so that the fixing piece 343 pulls the movable plate 342 downward at the same time, adjusting the distance between the brush 36 and the leakage plate 2, so that the upper surface of the brush 36 is below the lower surface of the leakage plate 2, and the brush 36 is not in close contact with the leakage hole 21.

[0033] The pressure sensing module 35 is used to determine the bending degree of the brush 36 according to the detected force signal, so as to evaluate whether the clogging of the hole 21 occurs. Specifically, when the brush 36 is in contact with the brushed object, the bristles will be subjected to the reaction force from the brushed object, which will be transmitted to the bottom of the brush 36 through the bristles and finally act on the pressure sensing module 35. The force detected by the pressure sensing module 35 is the size of the reaction force. The bristles will be elastically deformed, i.e. bent, when subjected to external force. According to Hooke's law, the deformation of the elastic body is proportional to the acting force. Therefore, the greater the bending degree of the bristles, the greater the force acting on the bristles. If the bending state of the bristles is uneven, i.e. part of the bristles has a greater bending degree and part of the bristles has a smaller bending degree, the force detected by the pressure sensing module 35 will also be uneven. This is because the bristles with a greater bending degree are subjected to a greater reaction force, and the bristles with a smaller bending degree are subjected to a smaller reaction force.

[0034] In one embodiment, as shown in Figure 6 、 Figure 7 The intermediate rod 32 is provided with a rotating rod 37, and the mounting plate 31 is provided with a fixed plate one 311 and a fixed plate two 312 matched with the rotating rod 37. The fixed plate one 311 and the fixed plate two 312 are provided with a space, and the rotating rod 37 is rotatably connected to the fixed plate one 311 and the fixed plate two 312 through the two ends of the rotating rod 37. The rotating rod 37 is rotatably matched with the fixed plate one 311.

[0035] The two ends of the rotating rod 37 are connected with a connecting rod 371, and the connecting rod 371 is located between the fixed plate one 311 and the fixed plate two 312. The connecting rod 371 is connected with a reset spring 372 between the connecting rod 371 and the fixed plate two 312. The other end of the connecting rod 371 is connected with a connecting shaft 373, and each connecting shaft 373 is hinged with a pressing rod 374.

[0036] It should be noted that, in the absence of external force, the connecting rod 371 maintains a vertical state with the fixed plate one 311 under the action of the reset spring 372, corresponding to the vertical state of the corrugated plate one 33. At this time, the height between the pressing rod 374 and the fixed plate one 311 is the largest. When the pressing rod 374 is pressed by external force, the pressing rod 374 drives the connecting rod 371 to rotate to one side through the connecting shaft 373, the height between the pressing rod 374 and the fixed plate one 311 is reduced, and the other end of the connecting rod 371 drives the rotating rod 37 to rotate, so that the rotating rod 37 drives the corrugated plate one 33 and the telescopic plate group to deflect by a certain angle, thereby adjusting the angle and adjusting the direct contact area between the exhaust gas and the surface of the corrugated plate one 33 and the telescopic plate group. When the external force pressing state is released, the reset spring 372 restores to the initial state and pulls the connecting rod 371 back to the vertical state.

[0037] As shown in Figure 8As shown, the tower body 1 surface is matched with the pressure rod 374 each set of a group of drive assembly 4, drive assembly 4 includes the mounting frame 41, the mounting frame 41 is fixed on the tower body 1 surface, the mounting frame 41 is provided with the drive rod 42, the drive rod 42 is rotatably connected with the mounting frame 41, the drive rod 42 is fixed with the drive block 43 at the end of the tower body 1, the drive rod 42 the other end is connected with the driver one 44, the mounting frame 41 both sides are fixed with the air cylinder 45, the driving end of the air cylinder 45 is connected with the connecting frame 46, the driver one 44 is installed on the connecting frame 46, the drive rod 42 is rotatably connected with the connecting frame 46.

[0038] In actual operation, the height of the drive assembly 4 is higher than the maximum height of the pressure rod 374, the shape of the drive block 43 is not unique, and it can be set according to the actual situation. In the non-working state, the air cylinder 45 pulls the driver one 44 away from the mounting frame 41 through the connecting frame 46, at this time the drive block 43 is away from the pressure rod 374, when the air cylinder 45 is contracted, the connecting frame 46 is pushed, so that the drive block 43 on the drive rod 42 is close to the pressure rod 374, and finally located above the pressure rod 374. When the driver one 44 drives the drive rod 42 to rotate, the drive rod 42 synchronously drives the drive block 43 to rotate, so as to realize the force on the pressure rod 374. According to the different rotating directions, the rotating direction of the connecting rod 371 driven by the pressure rod 374 is different, and the tilting direction of the corrugated plate one 33 and the telescopic plate group is also different.

[0039] As shown in Figure 2 , the mounting plate 31 is circumferentially connected with the annular plate 5, the annular plate 5 is provided with the limiting ring 6 upward and downward, the annular plate 5 is movably connected with the limiting ring 6, the outer part of the annular plate 5 is provided with the gear slot 51, and the tower body 1 is provided with the notch matched with the annular plate 5.

[0040] As shown in Figure 9 , Figure 10 , the surface of the tower body 1 is provided with the fixed frame 11, the driver two 12 is installed on the fixed frame 11, the driving end of the driver two 12 is sleeved with the gear one 13, the rotating shaft 14 is rotatably arranged on the fixed frame 11, the gear two 141 is sleeved with the gear three 142 on the rotating shaft 14 matched with the gear slot 51, and the gear three 142 is matched with the gear one 13.

[0041] In actual operation, the driver two 12 is used for controlling the rotating shaft 14 to rotate forward or reversely through the gear one 13 and the gear three 142, the rotating shaft 14 drives the gear two 141 to rotate, so that the annular plate 5 is synchronously rotated between the limiting rings 6. When the annular plate 5 rotates, the filler assembly 3 is driven to rotate as a whole, and the rotating angle range of the annular plate 5 satisfies that the drive assembly 4 and the filler assembly 3 will not collide. The rotation of the filler assembly 3 can adjust the position of the waste gas passage, agitate the waste gas to increase the contact area, and at the same time, the repeated rotation can make the brush 36 clean the surface of the leakage plate 2, thereby indirectly realizing the dredging of the leakage hole 21.

[0042] In one embodiment, as shown in Figure 9 The tower body 1 is provided with an air inlet 15 at the bottom and an air outlet 16 at the top, and the air outlet 16 is connected with a dehumidifier.

[0043] A spray pipe 17 is arranged in the tower body 1, the spray pipe 17 is located above the leakage plate 2, and a liquid output pipe 18 is connected to the bottom of the tower body 1.

[0044] The specific implementation method is as follows:

[0045] Step one: the spray pipe 17 sprays the purification liquid, and the treated fermentation waste gas enters the tower through the air inlet 15 at the bottom of the tower body 1;

[0046] Step two: the waste gas flows upward, first encounters the first leakage plate 2 at the lowermost layer, part of the waste gas rises through the leakage hole 21, and part of the waste gas is preliminarily intercepted by the leakage plate, the waste gas continues to rise and enters the filler assembly 3; the waste gas passes through the zigzag channel formed by the corrugated plate one 33 and the expansion plate group, and the corrugated plate structure greatly increases the surface area of gas-liquid contact; the spray pipe 17 located above the leakage plate 2 continuously sprays the absorption liquid (such as lye, water, etc.), and the liquid forms a liquid film on the surface of the corrugated plate of the filler assembly 3; the harmful components (such as acid gas, VOCs, etc.) in the waste gas and the absorption liquid occur physical dissolution or chemical reaction on the huge contact surface, and are effectively removed, and the purified gas continues to rise and passes through the second, third leakage plate 2 and the filler assembly 3 between them in turn, and the above-mentioned gas-liquid contact absorption process is repeated to realize multi-stage purification and ensure the treatment efficiency;

[0047] Step three: the waste liquid formed by the reaction of the spray liquid and the pollutants flows downward under the action of gravity, and finally falls layer by layer through the leakage hole 21 on the leakage plate 2, all the waste liquid is collected to the bottom of the tower body 1, and is discharged out of the tower through the liquid output pipe 18, and enters the subsequent liquid treatment system (such as a sedimentation tank, a circulating water tank, etc., which is pumped back to the spray pipe after treatment for recycling) ;

[0048] Step four: the gas after multi-stage purification reaches the top of the tower and is discharged from the air outlet 16, and the gas enters the dehumidifier (such as a wire mesh demister) to remove the water mist entrained therein, and is finally discharged to standard.

[0049] Specifically, in step two, the pressure sensing module 35 monitors the pressure on the brush 36 in real time. When the leakage hole 21 is partially blocked, the liquid flowing through the hole decreases, resulting in a decrease in the liquid impact force on the brush 36, and a decrease in the bending deformation of the brush 36, and a decrease in the pressure signal. When the pressure signal remains below the set threshold, it is determined that the area has a tendency to block. The electromagnetic module is powered off, and the brush 36 moves up under the action of the extension spring 346 and tightly contacts the leakage hole 21. The annular plate 5 is driven by the driver 2 to rotate slowly in forward and reverse directions, driving the entire filler assembly 3 to rotate, and the brush 36 at the bottom of the filler assembly 3 can clean the surface of the leakage plate 2 comprehensively, and dredge the blocked leakage hole 21. If the blockage is frequent, the filler angle can be adjusted to further increase the gas-liquid contact area and improve the waste gas purification efficiency.

A treatment method of a fermentation exhaust gas treatment apparatus, which is applied to the fermentation exhaust gas treatment apparatus according to claim 4, characterized by, The specific method is as follows: Step one: the spray pipe (17) sprays the purification liquid, the treated fermentation waste gas enters the tower through the air inlet (15) at the bottom of the tower body (1); Step two: the waste gas flows upwards, first encounters the first leakage plate (2) in the lowermost layer, part of the waste gas rises through the leakage hole (21), part of the waste gas is preliminarily intercepted by the leakage plate, the waste gas continues to rise and enters the filler assembly (3); the waste gas passes through the zigzag channel formed by the corrugated plate one (33) and the expansion plate group; the spray pipe (17) located on the upper side of the leakage plate (2) continuously sprays the absorption liquid downward, the liquid forms a liquid film on the surface of the corrugated plate one (33) and the expansion plate group in the filler assembly (3), the harmful components in the waste gas and the absorption liquid occur physical dissolution or chemical reaction on the contact surface, are effectively removed, the purified gas continues to rise and passes through the second, third leakage plate (2) and the filler assembly (3) between them in turn, repeats the above waste gas and absorption liquid contact reaction process; Step three: the waste liquid formed after the spray liquid reacts with the pollutants flows downward under the action of gravity, and finally falls through the leakage holes (21) on the leakage plate (2) layer by layer. All the waste liquid is collected at the bottom of the tower body (1) and discharged outside the tower through the liquid output pipe (18) to enter the subsequent liquid treatment system. Step four: the gas after multi-stage purification reaches the top of the tower and is discharged from the gas outlet (16). The gas enters the dehumidifier to remove the water mist entrained therein and is finally discharged up to standard.
