When the gas collecting and blocking tower works, gas penetrates through the annular plates 61 on the inner surface of the side wall of the tower body 11 through the gas outlet grooves 611 to enter the gas outlet pipe 5, the annular plates 61 are arranged in a plurality of layers up and down, the gas outlet grooves 611 are arranged in a staggered manner between the two adjacent layers of annular plates 61, the gas flows upwards from the gas outlet grooves 611 and then needs to flow for a certain distance along two sides of the two adjacent annular plates 61, and then the gas can flow upwards through the next gas outlet groove 611, namely the flowing gas slowly rises along a curved path, so that the distance of the gas flowing upwards between the annular plates 61 in the plurality of layers is increased, the contact time of the gas and the lower surface of each layer of annular plate 61 is prolonged, and the collecting and blocking capacity of the annular plates 61 on the micro-trimellitic benzene liquid beads is further improved; the joint part of the bottom end of the annular plate 61 and the outer surface of the side wall of the filter cylinder 62 is provided with a through groove 612, the pseudocumene droplets collected by the annular plate 61 at the middle layer flow back to the middle part of the tower body 11 through the through groove 612 again, the upper end of the through groove 612 is larger and beneficial to liquid inflow, the lower end is smaller, the gas flowing into the through groove 612 from the lower part is reduced, the phenomenon that the gas flowing into the through groove 612 obstructs the normal downward flow of the droplets in the through groove 612 due to excessive gas is avoided, and the working efficiency of the invention is further improved.
In an embodiment of the present invention, strings 613 are uniformly disposed between two ends of the air outlet groove 611 near the upper surface of the annular plate 61, and a metal sheet 614 is uniformly disposed on each string 613; each end face of the metal sheet 614 is parallel to the surface of the annular plate 61, and the surface of the metal sheet 614 is smooth; the metal sheets 614 are arranged on two adjacent strings 613 in a staggered manner; the lower surface of the metal sheet 614 is uniformly provided with drainage grooves 615, and the tail end of each drainage groove 615 close to the bottom of the annular plate 61 points to the direction of the string 613.
When the device works, gas passes through the gas outlet groove 611, the metal sheet 614 in the gas outlet groove 611 is in impact contact with the gas, and micro pseudocumene liquid beads in the gas are converged in the lower surface of the metal sheet 614, so that the collection capacity of the pseudocumene is further improved; the metal sheets 614 arranged on the two adjacent strings 613 in a staggered manner can prevent the metal sheets from colliding with each other after shaking due to gas impact, so that noise pollution is generated, and the working stability of the invention is improved; the metal sheet 614 and the string 613 are arranged near the upper surface of the annular plate 61, so that the flow of the liquid droplets on the metal sheet 613 is prevented from being obstructed by the gas flowing upwards; the drainage grooves 615 on the metal sheet 614 increase the surface area of the lower surface of the metal sheet 614 and can guide the liquid drops to the strings 613 and then flow down along the upper surface of the annular plate 61 in an inclined manner, thereby further improving the working efficiency of the invention.
As an embodiment of the present invention, the arc filter 623 is slidably connected to the top of the supporting plate 621, and the arc filter 623 has elasticity; a pressing plate 625 is arranged in the supporting plate 621, and a return spring 626 is arranged between the pressing plate 625 and the inner surface of the side wall of the tower body 11; the end part of the arc-shaped filter screen 623 is elastically connected with the side wall of the extrusion plate 625; the pressing plate 625 is slidably coupled to the lower end inner surface of the supporting plate 621 by a restoring spring 626.
When the carbon nonaarene raw liquid works, the carbon nonaarene raw liquid flows out from the tail end of the liquid inlet pipe 2 and impacts the surface of the arc-shaped filter screen 623, the arc-shaped filter screen 623 deforms due to the elasticity of the arc-shaped filter screen 623, the end part of the arc-shaped filter screen 623 extends towards the inner surface of the side wall of the filter cylinder 62, and the end part of the arc-shaped filter screen 623 is elastically connected with the extrusion plate 625, so that the extrusion plate 625 is pushed to move outwards; when the extrusion plate 625 moves towards the inner surface of the side wall of the filter cartridge 62, impurity particles and dirt accumulated on the inner surface of the bottom end of the support plate 621 are cleaned, the side filter screen 622 is prevented from being blocked due to long-term accumulation of the impurity particles and the dirt on the inner surface of the bottom end of the support plate 621, and meanwhile, a small amount of carbon nonaromatic hydrocarbon stock solution contained in the impurity particles and the dirt is overflowed due to extrusion of the extrusion plate 625, so that the passing efficiency of the carbon nonaromatic hydrocarbon stock solution is improved; the pressing plate 625 is returned to the original position by the restoring spring 626, further improving the working efficiency of the present invention.
As an embodiment of the present invention, a turbine 21 is disposed in the liquid inlet pipe 2 near the turning position in the tower body 1, and a fixing rod 211 is disposed on a surface of one blade of the turbine 21; two limiting rings 212 which are parallel are arranged at the position, close to the middle part, of the fixing rod 211; the fixing rod 211 is provided with a rotating ring 213, and the rotating ring 213 is nested between the two limiting rings 212 and is rotatably connected; an elastic rope 214 is arranged in the rotating ring 213, and the bottom end of the elastic rope 214 penetrates out of the middle position of the liquid inlet pipe 2 and is fixedly connected with the arc-shaped filter screen 623.
When the device works, the carbon nonaarene stock solution flows into the light component removal tower body 1 through the liquid inlet pipe 2, the turbine 21 in the liquid inlet pipe 2, which is close to the turning part, rotates due to liquid flowing, and the turbine 21 rotates to stir the carbon nonaarene stock solution with higher viscosity, so that the flow rate of the liquid flowing to the arc-shaped filter screen 623 is increased, and the filtering efficiency is further improved; when the fixing rod 211 moves from the lowest point to the highest point along with the blades of the turbine 21, the middle part of the arc-shaped filter screen 623 is stretched upwards through the elastic rope 214, the end part of the arc-shaped filter screen 623 gradually gets away from the inner surface of the side wall of the filter cartridge 62, the thrust force applied to the pressing plate 625 is reduced, and the pressing plate 625 is further restored to the initial position under the cooperation of the restoring spring 626; when the fixing rod 211 moves from the highest point to the lowest point along with the blades of the turbine 21, the upward force applied to the arc-shaped filter screen 623 is reduced, the end part of the arc-shaped filter screen 623 is gradually close to the inner surface of the side wall of the filter cylinder 62, the thrust applied to the extrusion plate 625 is increased, and the extrusion effect of the extrusion plate 625 on impurity particles and dirt is further increased; under the matching action of the turbine 21 and the elastic rope 214, once the turbine 21 rotates for one circle, namely the arc-shaped filter screen 623 fixedly connected with the tail end of the elastic rope 214 can generate elastic deformation, the elastic deformation degree of the arc-shaped filter screen 623 is improved, the extrusion effect of the extrusion plate 625 on impurity particles and dirt is increased, and the filtering efficiency of the arc-shaped filter screen 623 and the side filter screen 622 is further improved; the rotation ring 213 is connected with the elastic cord 214 to prevent the elastic cord 214 from winding around the fixing rod 211 when rotating; the rotating ring 213 is disposed between the two limiting rings 212, so that the upper end of the elastic cord 214 does not fall off the horizontal range of the fixing rod 211 in the process of rotating along with the turbine 21, and the elastic cord 214 is prevented from being wound on the blades of the turbine 21 in motion, thereby further improving the working efficiency of the present invention.
The specific working process is as follows:
the carbon nonaarene stock solution is downwards introduced into the light component removal tower body 1 from the liquid inlet pipe 2, simultaneously, the ethanol vapor is upwards introduced into the light component removal tower body 1 from the gas collecting pipe, when the carbon nonaarene stock solution flows through the arc-shaped filter screen 623, most of the carbon nonaarene stock solution falls into the bottom of the filter cylinder 62 through the arc-shaped filter screen 623, and impurity particles and dirt in the carbon nonaarene stock solution are blocked by the filter screen; because the end part of the liquid inlet pipe 2 in the filter cartridge 62 is directly opposite to the middle position of the arc-shaped filter screen 623, that is, the position where the carbon nonaromatic raw liquid contacts the arc-shaped filter screen 623 is the highest position of the arc-shaped filter screen 623, the impurity particles and the dirt flow down along the arc surface along with a small part of the carbon nonaromatic raw liquid to the periphery and finally converge in the bottom end of the support plate 621 on the side wall of the filter cartridge 62, and the small part of the carbon nonaromatic raw liquid on the upper surface of the bottom end of the support plate 621 flows to the bottom of the filter cartridge 62 again through the side filter screen 622; the arc-shaped filter screen 623 and the side filter screen 622 are matched to effectively remove residual impurity particles and dirt in the carbon nonaromatic raw liquid, so that the impurity particles and the dirt are prevented from flowing into the spray head 65 through the liquid collecting pipe 63 and the liquid distributing pipe 64 to cause blockage and even damage to the spray head 65, and further the lightness removing efficiency is influenced; because the arc-shaped filter screen 623 has elasticity, the impact of the carbon nonaarene stock solution causes the arc-shaped filter screen 623 to deform, the end part of the arc-shaped filter screen 623 extends towards the inner surface of the side wall of the filter cartridge 62, and the end part of the arc-shaped filter screen 623 contacts the extrusion plate 625, so that the extrusion plate 625 is pushed to move outwards; when the extrusion plate 625 moves towards the inner surface of the side wall of the filter cartridge 62, impurity particles and dirt accumulated on the inner surface of the bottom end of the support plate 621 are cleaned, the side filter screen 622 is prevented from being blocked due to long-term accumulation of the impurity particles and the dirt on the inner surface of the bottom end of the support plate 621, and meanwhile, a small amount of carbon nonaromatic hydrocarbon stock solution contained in the impurity particles and the dirt is overflowed due to extrusion of the extrusion plate 625, so that the passing efficiency of the carbon nonaromatic hydrocarbon stock solution is improved; meanwhile, under the matching action of the blades of the turbine 21 and the elastic ropes 214, the arc-shaped filter screen 623 can generate elastic deformation once when the turbine 21 rotates for one circle, so that the elastic deformation degree of the arc-shaped filter screen 623 is improved, namely the extrusion effect of the extrusion plate 625 on impurity particles and dirt is increased, and the filtering efficiency of the arc-shaped filter screen 623 and the side filter screen 622 is further improved; the side wall of the bottom end of the filter cylinder 62 is inverted cone-shaped, so that the carbon nonaromatic raw liquid filtered at the upper part of the filter cylinder 62 can be converged to the top end of the liquid collecting pipe 63 in the downward flowing process, the flow of the carbon nonaromatic raw liquid required by the spray head 65 at the bottom end of the liquid separating pipe 64 is sufficient, and the condition that the spray head 65 uniformly sprays the carbon nonaromatic raw liquid is provided; the nozzle 65 continuously sprays the carbon nonaromatic hydrocarbon stock solution onto the packing layer 66, the carbon nonaromatic hydrocarbon stock solution extends below the packing layer 66 to wet the surface of the packing, and simultaneously, the ethanol vapor flowing upwards from the lower surface of the packing layer 66 moves along gaps between the packing layers 66, so that gas-liquid two phases are fully contacted to transfer heat and carry out mass transfer; when the device works, the temperature in the lightness-removing tower body 1 is controlled to be kept at 166-168 ℃, because the boiling point of the pseudocumene is 169.35 ℃, and the boiling point of most other substances in the carbon nonaromatic hydrocarbon stock solution is lower than 166 ℃, the pseudocumene in the carbon nonaromatic hydrocarbon stock solution does not reach the boiling point and falls into a collecting pipe 67 at the bottom of the lightness-removing tower body 1, the collecting pipe 67 is in an inverted cone shape, so that the pseudocumene is collected to the top end of a liquid outlet pipe 3 in the flowing process, and the collecting efficiency of the pseudocumene is improved; meanwhile, most other substances in the carbon nonaromatic hydrocarbon stock solution reach the boiling point, become gaseous and enter ethanol vapor through mass transfer, most target products, namely the pseudocumene, flow into the collecting pipe 67 from the packing layer 66, and a small amount of tiny pseudocumene liquid beads rise along with the ethanol vapor; when the gas contacts the annular plate 61, because the annular plate 61 is obliquely arranged and has a smooth surface, the tiny liquid beads in the gas gradually gather on the lower surface of the annular plate 61 to form liquid beads with larger volume; one part of the liquid beads directly drops from the lower surface of the annular plate 61 to the packing layer 66, and the other part flows along the inclined lower surface of the annular plate 61 and finally returns to the packing layer 66; the arrangement of the annular plate 61 can enable the micro pseudocumene liquid mixed in the ethanol gas to return to the packing layer 66 again, thereby avoiding the waste of target products and improving the working efficiency of the invention; the annular plates 61 are arranged in a plurality of layers up and down, the gas outlet grooves 611 are arranged between every two layers of annular plates 61 in a staggered mode, so that the upward flowing path of gas between the annular plates 61 is increased, the contact time of the gas and the lower surface of each layer of annular plate 61 is prolonged, the metal sheets 614 in the gas outlet grooves 611 are in impact contact with the gas, small pseudocumene liquid beads in the gas are converged in the lower surfaces of the metal sheets 614, and the pseudocumene collecting capacity is further improved; finally, the gas is discharged out of the lightness removing tower body 1 through a gas outlet pipe 5 at the middle position of a tower cover 12; according to the invention, the carbon nonaromatic hydrocarbon stock solution is filtered and treated by arranging the arc-shaped filter screen 623, so that impurity particles and dirt in the carbon nonaromatic hydrocarbon stock solution are removed, the problem of easy blockage during liquid spraying is solved, and the small liquid beads of the pseudocumene mixed in the gas are collected and treated by arranging the inclined annular plate 61, the gas outlet groove 611 and the metal sheet 614, so that the production efficiency of a target product is improved, the resource waste is avoided, and the energy consumption is reduced.
