Detailed Implementation

[0033] Currently, spray scrubbing is only downward spray scrubbing, which has two problems: first, the downward sprayed liquid falls in a columnar shape due to gravity, resulting in insufficient gas-liquid contact area; second, downward spray scrubbing has blind spots, allowing some waste gas to escape directly without treatment, both of which lead to poor waste gas treatment effect.

[0034] In view of this, the present application provides an organic waste gas treatment tower, which is designed to spray purification liquid downward through a first nozzle, achieve horizontal spraying through a multi-layer nozzle group, and further combine with a drive installation component to drive the spray pipe to rotate, forming a three-dimensional spray coverage of waste gas. This not only increases the gas-liquid contact area but also increases the gas-liquid contact time, and eliminates spray blind spots, achieving a more efficient waste gas treatment effect. It solves the technical problem in the prior art that the gas washing is only downward spraying, resulting in insufficient gas-liquid contact area and the existence of spray blind spots, causing some waste gas to escape directly without treatment, thus leading to poor waste gas treatment effect.

[0040] This application provides an organic waste gas treatment tower, such as... Figures 1 to 5 As shown. An organic waste gas treatment tower includes a vertical tower body 1 and a tower top 2. The bottom of the vertical tower body 1 is provided with an air inlet 3, and the top of the tower top 2 is provided with an exhaust outlet 4, the bottom of which is connected to the top of the vertical tower body 1.

[0041] Specifically, the vertical tower body 1 and the tower top 2 are detachably connected, and both the vertical tower body 1 and the tower top 2 are provided with observation windows 22.

[0042] The vertical tower body 1 and the tower top 2 can be detachably connected by flange docking, or by the tower top 2 fitting into the interior of the vertical tower body 1 and being secured with bolts. It should be noted that this application does not specifically limit the specific detachable connection method of the vertical tower body 1 and the tower top 2. Those skilled in the art can design a suitable connection structure according to actual needs. By setting the vertical tower body 1 and the tower top 2 to be detachably connected, it is convenient to clean the interior of the vertical tower body 1 and the tower top 2, and it is also convenient to repair and replace the internal structure of the vertical tower body 1. By setting the observation window 22, it is convenient for staff to observe and handle the internal condition of the tower in real time.

[0043] The interior of the vertical tower body 1 is provided with an adsorption zone and a spray assembly from top to bottom. The spray assembly includes a drive mounting assembly, a spray pipe 5, a liquid receiving pipe 6, a first nozzle 7, and several nozzle groups. The spray pipe 5 is vertically arranged along the central axis of the vertical tower body 1 and is connected to the drive mounting assembly. The drive mounting assembly is connected to the vertical tower body 1 and is used to drive the spray pipe 5 to rotate. The liquid receiving pipe 6 is located above the drive mounting assembly, with one end connected to the top of the spray pipe 5 and the other end connected to a purification liquid assembly located outside the vertical tower body 1. The first nozzle 7 is vertically arranged at the end of the spray pipe 5 away from the liquid receiving pipe 6 to spray the purification liquid downwards. Several nozzle groups are spaced apart at the end of the spray pipe 5 away from the liquid receiving pipe 6 to spray the purification liquid horizontally.

[0044] In this system, the spray pipe 5 is driven to rotate by a drive installation component and combined with the multi-layer nozzle group to achieve circumferential spraying of the purification liquid. Combined with the downward spraying of the purification liquid by the first nozzle 7, the system achieves three-dimensional spraying coverage of the exhaust gas. This not only increases the gas-liquid contact area and gas-liquid contact time, but also completely eliminates spray blind spots, thus achieving efficient treatment of the exhaust gas.

[0045] Specifically, the adsorption zone includes a dehydration plate 23, a water-absorbing sponge plate 24, a bamboo charcoal fiber plate 25, and an activated carbon adsorption plate 26. The dehydration plate 23, the water-absorbing sponge plate 24, the bamboo charcoal fiber plate 25, and the activated carbon adsorption plate 26 are distributed alternately from bottom to top and are all connected to the vertical tower body 1.

[0046] The dehydration plate 23 is used to remove free moisture and protect the downstream adsorption layer. The water-absorbing sponge plate 24 is used to absorb droplets and water-soluble pollutants to reduce the humidity of the exhaust gas. The bamboo charcoal fiber plate 25 is used to absorb macromolecular organic matter (such as oils, resin-based VOCs, etc.) and particulate heavy metals (such as mercury vapor, lead dust, etc.) as a pre-filter layer for the activated carbon adsorption plate 26 to pre-filter the exhaust gas, effectively preventing the activated carbon adsorption plate 26 from clogging and slowing down the saturation rate of the activated carbon. The activated carbon adsorption plate 26 is used to adsorb volatile organic compounds (benzenes, aldehydes, ketones, etc.), some inorganic harmful gases (such as hydrogen sulfide, ammonia, etc.), and odor molecules (such as thiols, amines, and other malodorous substances) to achieve deep purification and ensure that the exhaust gas meets emission standards.

[0047] Specifically, the drive mounting assembly includes a fixing pipe 8, a mounting box 9, a drive shaft 10, a first bevel gear 11, a second bevel gear 12, and a drive motor 13. The fixing pipe 8 is connected to the vertical tower body 1 radially and has a mounting cavity 14 inside. One end of the mounting cavity 14 communicates with the outside of the vertical tower body 1, and the other end communicates with the mounting box 9. The drive shaft 10 is located in the mounting cavity 14, with one end located outside the vertical tower body 1 and connected to the drive motor 13, and the other end located inside the mounting box 9. The mounting box 9 is located on the central axis of the vertical tower body 1. The spray pipe 5 vertically passes through the mounting box 9 and is rotatably connected to the mounting box 9 through a bearing. The first bevel gear 11 and the second bevel gear 12 are both located inside the mounting box 9. The first bevel gear 11 is connected to the drive shaft 10. The spray pipe 5 is fixedly connected to the second bevel gear 12. The first bevel gear 11 and the second bevel gear 12 mesh. The liquid receiving pipe 6 is connected to the end of the spray pipe 5 located above the mounting box 9. The first nozzle 7 and several nozzle groups are located below the mounting box 9. Each nozzle group includes at least three second nozzles 20. The at least three second nozzles 20 are arranged laterally and are evenly distributed along the circumference of the spray pipe 5. The purification liquid assembly includes a delivery pipe 16, a check valve 17, a water pump 18, and a purification liquid tank 19. One end of the delivery pipe 16 is connected to the liquid receiving pipe 6, and the other end is connected to the check valve 17. The other end of the check valve 17 is connected to the water pump 18, and the other end of the water pump 18 is connected to the purification liquid tank 19. The purification liquid tank 19 is used to store the waste gas purification liquid.

[0048] The specific number of the second nozzles 20 in each nozzle group is determined according to the spray coverage angle of the second nozzles 20. It is only necessary to ensure that a number of the second nozzles 20 can spray 360° full coverage. In this embodiment, a rotary joint 21 is provided inside the vertical tower body 1. The rotary joint 21 is located above the drive mounting assembly. Specifically, the rotary joint 21 is located above the mounting box 9. One end of the rotary joint 21 is connected to the spray pipe 5, and the other end is connected to the liquid receiving pipe 6. To prevent the spray pipe 5 from moving axially, a limiting block (not shown in the figure) can be provided on the spray pipe 5. The limiting block can be provided at one end of the spray pipe 5 located on the mounting box 9 and slidably supported on the top of the mounting box 9.

[0049] In some preferred embodiments, a spiral guide plate 15 is provided inside the vertical tower body 1. The spiral guide plate 15 is located below the mounting box 9 and surrounds the outer periphery of the spray pipe 5.

[0050] Specifically, the pitch of the spiral guide plate 15 is defined as D, the distance between two adjacent nozzle groups is d, and the distance between the first nozzle group above the spiral guide plate 15 and the spiral guide plate 15 is L. Then, L > 0 and L < d = D / 2 are satisfied. The outer diameter of the spiral guide plate 15 is equal to the inner diameter of the vertical tower body 1. The inner diameter of the spiral guide plate 15 is slightly larger than the sum of the diameter of the spray pipe 5 and twice the length of the second nozzle 20, so as to avoid the spiral guide plate 15 affecting the rotation of the second nozzle 20 and the spray pipe 5.

[0051] The spiral guide plate 15 is installed to improve airflow distribution, so that the waste gas is evenly distributed in the treatment tower, enhance gas-liquid contact efficiency, and thus improve the waste gas treatment effect.

[0052] In some preferred embodiments, the cross-section of the fixing tube 8 perpendicular to its axial direction is triangular, and the bottom of the mounting box 9 is configured as a frustum structure, with the smaller end facing the nozzle assembly.

[0053] Specifically, by setting the cross-section of the fixed pipe 8 perpendicular to its axial direction to be triangular, and setting the bottom of the mounting box 9 to be a frustum structure, the obstruction of the fixed pipe 8 and the mounting box 9 to the rise of exhaust gas is reduced, and the technical effect of exhaust gas diversion and flow diversion is achieved.

[0054] In some preferred embodiments, the inner wall of the top of the vertical tower body 1 is provided with a first sliding groove 27, a second sliding groove 28, a third sliding groove 29, and a fourth sliding groove 30. The first sliding groove 27, the second sliding groove 28, the third sliding groove 29, and the fourth sliding groove 30 are symmetrically distributed around the central axis of the vertical tower body 1. The length of the first sliding groove 27 is defined as H1, the length of the second sliding groove 28 as H2, the length of the third sliding groove 29 as H3, and the length of the fourth sliding groove 30 as H4, satisfying H1 > H2 > H3 > H4. The dehydration plate 23 is slidably connected in the first sliding groove 27, the water-absorbing sponge plate 24 is slidably connected in the first sliding groove 27 and the second sliding groove 28, the bamboo charcoal fiber plate 25 is slidably connected in the first sliding groove 27, the second sliding groove 28, and the third sliding groove 29, and the activated carbon adsorption plate 26 is slidably connected in the first sliding groove 27, the second sliding groove 28, the third sliding groove 29, and the fourth sliding groove 30.

[0055] The first chute 27, the second chute 28, the third chute 29, and the fourth chute 30 are all two in number and symmetrically distributed around the central axis of the vertical tower body 1. The projections of the lines connecting the two first chute 27s, the two second chute 28s, the two third chute 29s, and the two fourth chute 30 on the horizontal plane are all set at certain angles and do not overlap. The dewatering plate 23 is slidably connected to the first chute 27, the water-absorbing sponge plate 24 is slidably connected to the first chute 27 and the second chute 28, the bamboo charcoal fiber plate 25 is slidably connected to the first chute 27, the second chute 28, and the third chute 29, and the activated carbon adsorption plate 26 is slidably connected to the first chute 27, the second chute 28, the third chute 29, and the fourth chute 30. Within the fourth chute 30, the dehydration plate 23, the absorbent sponge plate 24, the bamboo charcoal fiber plate, and the activated carbon adsorption plate 26 are detachably connected to the vertical tower body 1, facilitating the replacement of these components. Through the sequence H1 > H2 > H3 > H4, the dehydration plate 23, the absorbent sponge plate 24, the bamboo charcoal fiber plate, and the activated carbon adsorption plate 26 are installed in layers. It should be noted that the dehydration plate 23 has a corresponding set of opposing sliders, the absorbent sponge plate 24 has two corresponding sets of opposing sliders, the bamboo charcoal fiber plate has three corresponding sets of opposing sliders, and the activated carbon adsorption plate 26 has four corresponding sets of opposing sliders. This allows the upper plate to simultaneously seal the corresponding chute of the lower plate, preventing exhaust gas from escaping.

[0056] In summary, the organic waste gas treatment tower provided in this application provides a method that sprays purification liquid downward through a first nozzle, achieves horizontal spraying through a multi-layer nozzle group, and further combines a drive installation component to drive the spray pipe to rotate, forming a three-dimensional spray coverage of the waste gas. This not only increases the gas-liquid contact area but also increases the gas-liquid contact time and eliminates spray blind spots, achieving a more efficient waste gas treatment effect. It solves the technical problem in the prior art where the spray washing is only downward, resulting in insufficient gas-liquid contact area and the existence of spray blind spots, causing some waste gas to escape directly without treatment, thus leading to poor waste gas treatment effect.
