Description

Technical Field

[0001] The utility model belongs to the technical field of chemical equipment, and specifically relates to a VOCs waste gas dephenolization centralized treatment tower. Background Art

[0002] The technologies for treating phenol-containing waste gas include adsorption, absorption, biodegradation, photocatalytic degradation, etc. Among them, adsorption, biodegradation, photocatalytic degradation and other methods are often used for treating phenol-containing wastewater, while phenolic substances are not destroyed during physical treatment and can be recycled. Traditional physical methods usually preliminarily treat the waste gas through condensation, then adsorb the phenolic substances in the waste gas by spraying liquid, and finally adsorb it through activated carbon. However, the adsorption effect of activated carbon is poor. The adsorption capacity of algae calcium is thousands of times that of activated carbon. When algae calcium is adsorbed, large crystal particles will precipitate due to the phenolic substances, resulting in blockage of the pore structure in the algae calcium. At this time, the algae calcium needs to be replaced. The traditional replacement requires stopping the operation of the device, resulting in the working efficiency of the device being affected, and most of the existing devices cannot accurately determine when to replace the algae calcium.

The air inlet 3 is installed below the side wall of the main body 1, the controller 2 and the spray mechanism 4 are installed on the main body 1, the exhaust pipe 6 is installed on the top of the main body 1, the electric valve 5 is installed at the connection between the main body 1 and the exhaust pipe 6, the electric telescopic rod 7 and the filter mechanism 8 are installed on the exhaust pipe 6, the sealing ring 9 is slidably installed on the inner wall of the exhaust pipe 6, the detector 91 is installed on the inner wall of the sealing ring 9, and the telescopic end of the electric telescopic rod 7 is installed on the sealing ring 9.

[0023] The filtering mechanism 8 includes a motor 81, a turntable 82, a shell 83, screws 84, a filter block 85, a sealing groove 1 86, a mounting ring 87, a spring 88, a movable groove 89, a sealing groove 2 810, a sealing gasket 811 and a protective shell 812. The motor 81 is installed on the top of the main body 1, and the turntable 82 is installed on the motor 81. A groove matching the turntable 82 is provided on the side wall of the exhaust pipe 6. Several shells 83 are annularly installed on the turntable 82. The shells 83 are fixed to the turntable 82 by screws 84. The filter block 85 is slidably installed on the shell 83. A mounting ring 87 is installed on the inner wall of the shell 83. A movable groove 89 matching the mounting ring 87 is provided on the side wall of the frame of the filter block 85. The mounting ring 87 is installed on the movable groove 89 by a spring 88.

[0024] The user can control the various electrical components of the device through the controller 2, which is convenient for the user to control the operation of the device. The air inlet 3 is used to deliver the waste gas to be treated into the interior of the main body 1. After the waste gas enters the interior of the main body 1 through the air inlet 3, it will flow upward. The rising waste gas will pass through the spray mechanism 4 and the filter mechanism 8. The cooperation of the spray mechanism 4 and the filter mechanism 8 can separate the phenolic substances in the waste gas from the waste gas, thereby realizing the dephenolization of the waste gas. The waste gas after treatment will be discharged from the device through the exhaust pipe 6. The installation position of the electric valve 5 enables the electric valve 5 to control the opening and closing of the exhaust pipe 6, thereby realizing the sealing of the waste gas in the main body 1 by the electric valve 5. The working effect of the filter mechanism 8 will decrease during long-term use. At this time, the filter mechanism 8 needs to be replaced. When the user replaces the filter mechanism 8, the main body 1 can be sealed by the electric valve 5 to avoid To prevent the exhaust gas from being discharged during the process of the user replacing the filter mechanism 8, which affects the environment and the user's health, the sealing ring 9 can be used to seal the gap between the exhaust pipe 6 and the filter mechanism 8 to prevent the exhaust gas from leaking during the treatment process, which affects the working effect of the device. The position of the sealing ring 9 can be controlled by the electric telescopic rod 7 to control whether the sealing ring 9 seals the gap between the exhaust pipe 6 and the filter mechanism 8 to prevent the user from being obstructed by the sealing ring 9 during the process of replacing the filter mechanism 8. The detector 91 can be used to detect the amount of phenolic substances in the exhaust gas discharged from the exhaust pipe 6. When the exhaust gas is unqualified, the detector 91 will transmit a signal to the controller 2 to remind the user to replace the filter mechanism 8. The detector 91 is installed on the inner wall of the sealing ring 9 to ensure that the lifting of the sealing ring 9 will not affect the working effect of the detector 91.

[0025] The motor 81 can provide power for the rotation of the turntable 82. The filter block 85 is used to filter the exhaust gas. When the exhaust gas passes through the filter block 85, the phenolic substances in the exhaust gas will be adsorbed on the filter block 85, thereby realizing the separation of the phenolic substances contained in the exhaust gas. The shell 83 is installed on the turntable 82 by means of screws 84, which is convenient for the user to disassemble the shell 83, thereby reducing the difficulty for the user to replace the used filter block 85. The filter block 85 is installed on the turntable 82 by means of the shell 83. When the filter block 85 needs to be replaced, it is only necessary to control the rotation of the turntable 82 by means of the motor 81 to complete the replacement of the filter block 85. The rotating turntable 82 will take the filter block 85 that needs to be replaced away from the exhaust pipe 6 while sending the new filter block 85 into the exhaust pipe 6, thereby reducing the difficulty for the user to replace the filter block 85 and improving the working efficiency of the device. Several filter blocks 85 are installed on the turntable 82. When the device is used, the user can replace the used filter block 85, thereby improving the working efficiency of the device. After entering the exhaust pipe 6, the electric telescopic rod 7 controls the sealing ring 9 to move downward, and the sealing ring 9 moving downward will push the filter block 85. The filter block 85 moves downward under the action of the sealing ring 9, and the sealing ring 9 seals the gap between the top surface of the turntable 82 and the exhaust pipe 6. The frame of the filter block 85 seals the gap between the bottom surface of the turntable 82 and the exhaust pipe 6, ensuring the sealing of the exhaust pipe 6 during use, avoiding leakage of exhaust gas during the treatment process, resulting in the working effect of the device being affected. The cooperation between 87 and the movable groove 89 can ensure the stability of the filter block 85 during the movement. The spring 88 supports the filter block 85 to ensure that when the filter block 85 is not suppressed by external force, the top and bottom surfaces of the filter block 85 are on the same plane as the top and bottom surfaces of the turntable 82, ensuring that the filter block 85 will not hinder the rotation of the turntable 82. After the sealing ring 9 releases the suppression of the filter block 85, the filter block 85 quickly returns to its original position under the action of the spring 88, ensuring that the rotation of the turntable 82 will not be hindered.

[0026] Specifically, a sealing groove 1 86 is provided on the top of the frame of the filter block 85, a protrusion matching the sealing groove 1 86 is provided on the bottom surface of the sealing ring 9, a sealing groove 2 810 matching the filter block 85 is provided on the inner wall of the exhaust pipe 6, and a sealing gasket 811 is provided on the side walls of the sealing groove 1 86 and the sealing groove 2 810.

[0027] The cooperation between the sealing groove 1 86 and the bottom protrusion of the sealing ring 9 ensures the sealing effect of the sealing ring 9 on the gap between the top surface of the turntable 82 and the exhaust pipe 6. The cooperation between the filter block 85 and the sealing groove 2 810 ensures the sealing effect of the filter block 85 on the gap between the bottom surface of the turntable 82 and the exhaust pipe 6. The sealing gasket 811 further improves the sealing effect of the filter block 85 and the sealing ring 9.

[0028] Specifically, a groove is provided at the position where the screw 84 is installed on the shell 83, and the height of the groove of the shell 83 is greater than the distance between the top surface of the screw 84 and the bottom surface of the groove of the shell 83 after the screw 84 is installed.

[0029] The height of the groove on the housing 83 ensures that after the screw 84 fixes the housing 83 on the turntable 82, the screw 84 completely enters the interior of the turntable 82, thereby preventing the rotation of the turntable 82 from being affected due to the top surface of the screw 84 being higher than the top surface of the turntable 82.

[0030] Specifically, a protective shell 812 matching the turntable 82 is provided at the position where the groove is opened on the side wall of the exhaust pipe 6 , and a sealing door is provided on the protective shell 812 .

[0031] The protective shell 812 can protect the filter block 85, prevent the filter block 85 to be used from being affected by the external environment during the operation of the device, ensure that the service life of the filter block 85 to be used is not affected by the external environment, ensure the working effect of the device, reduce the frequency of users replacing the filter block 85, and improve the working efficiency of the device. The position of the sealing door set on the protective shell 812 is located at the position where one of the filter blocks 85 is located inside the exhaust pipe 6. The sealing door set on the protective shell 812 ensures the protective effect of the protective shell 812 while facilitating the user to replace the used filter block 85.

[0032] Specifically, the spray mechanism 4 includes a water pump 41, a cooler 42, a spiral tube 43, a partition 44, a through hole 45, a through pipe 46 and a liquid storage tank 47. The liquid storage tank 47 is installed at the bottom of the main body 1, and the water pump 41 is installed on the side wall of the liquid storage tank 47. The spiral tube 43 is installed inside the side wall of the main body 1, and the spiral tube 43 is connected to the liquid storage tank 47 through the water pump 41. The water pump 41 connecting the main body 1 and the liquid storage tank 47 is installed at the bottom of the side wall of the main body 1. Several partitions 44 are installed on the inner wall of the main body 1, and several through holes 45 are evenly opened on the partition 44. A through pipe 46 connected to the spiral tube 43 is installed on the side wall of the through hole 45.

[0033] The liquid storage tank 47 stores a liquid that can dissolve phenolic substances. When the exhaust gas contacts the liquid, the phenolic substances in the exhaust gas will dissolve into the liquid, thereby separating the phenolic substances in the exhaust gas. The water pump 41 can provide power for the flow of the liquid. The water pump 41 connected to the spiral tube 43 will transport the liquid in the liquid storage tank 47 to the inside of the spiral tube 43. The partition 44 can divide the inside of the main body 1 into several spaces. The through holes 45 opened on the partition 44 are used for the exhaust gas to circulate in the inside of the main body 1. By setting a plurality of through holes 45, the air permeability of the partition 44 is guaranteed, and the liquid in the spiral tube 43 During the flow, the waste gas will be sprayed into the interior of the through hole 45 through the through pipe 46. When the waste gas flows through the through hole 45, the waste gas will come into contact with the liquid. By setting the through hole 45, it can be ensured that the waste gas can come into contact with the liquid more comprehensively, thereby ensuring the dephenolization effect of the device. By setting a plurality of partitions 44, the dephenolization effect of the spray mechanism 4 is further improved. The water pump 41 connected to the main body 1 can return the liquid that has absorbed phenolic substances to the interior of the liquid storage tank 47, thereby realizing the recycling of the liquid and reducing waste. The user should regularly replace the liquid in the liquid storage tank 47 to ensure the dephenolization effect of the spray mechanism 4.

[0034] Specifically, a certain amount of liquid remains at the bottom of the main body 1 , the liquid level inside the main body 1 is higher than the position where the water pump 41 is connected to the main body 1 , and the liquid level inside the main body 1 is lower than the position where the air inlet 3 is connected to the main body 1 .

[0035] The liquid retained at the bottom of the main body 1 can play a liquid seal effect, preventing the exhaust gas delivered into the main body 1 by the air inlet 3 from entering the liquid storage tank 47 through the water pump 41 connected to the main body 1, which would affect the working effect of the device. The position of the liquid level inside the main body 1 ensures that the gas delivered into the main body 1 by the air inlet 3 will not enter the liquid inside the main body 1, further ensuring the working effect of the device.

[0036] Specifically, a cooler 42 is installed on the liquid storage tank 47 .

[0037] The cooler 42 can lower the temperature of the liquid inside the liquid storage tank 47. The low-temperature liquid is sent into the interior of the spiral tube 43 by the water pump 41. As the liquid flows, the low-temperature liquid will lower the temperature inside the main body 1. The shape of the spiral tube 43 increases the internal movement range of the liquid on the side wall of the main body 1, ensuring the cooling effect of the low-temperature liquid. Some phenolic substances in the exhaust gas will be liquefied under the action of low temperature, thereby improving the working effect of the device.

[0038] The working principle and use process of the utility model are as follows: the water pump 41 and the cooling machine 42 are started, the cooling machine 42 reduces the temperature of the liquid inside the liquid storage tank 47, the water pump 41 connected with the spiral tube 43 sends the liquid inside the liquid storage tank 47 into the inside of the spiral tube 43, the liquid inside the spiral tube 43 is sprayed into the inside of the through hole 45 through the through pipe 46, and finally the liquid enters the bottom of the main body 1, the liquid inside the main body 1 is sent back to the liquid storage tank 47 by the water pump 41 connected with the main body 1, the exhaust gas is sent into the inside of the main body 1 through the air inlet 3, the exhaust gas sent into the inside of the main body 1 will flow upward through the through hole 45, the flowing gas and the liquid will contact to achieve the preliminary dephenolization of the exhaust gas, and then the gas enters the exhaust pipe 6, the exhaust gas entering the exhaust pipe 6 leaves the device after passing through the filter block 85, the detector 91 will detect the phenol content of the exhausted exhaust gas, when the data detected by the detector 91 does not meet the standard, the electric valve 5 is closed, the electric telescopic rod 7 is controlled to extend, and the sealing ring 9 is released from the filter The filter block 85 is suppressed, and the filter block 85 returns to its original position under the action of the spring 88, and the motor 81 is started. The motor 81 rotates the turntable 82, and the rotating turntable 82 replaces the filter block 85. After the new filter block 85 enters the interior of the exhaust pipe 6, the motor 81 is turned off, and the electric telescopic rod 7 is controlled to shrink. The sealing ring 9 moves downward under the action of the electric telescopic rod 7, and the bottom protrusion of the sealing ring 9 enters the sealing groove 1 86. The downward-moving sealing ring 9 will push the filter block 85 into the sealing groove 2 810, thereby sealing the gap between the exhaust pipe 6 and the turntable 82 and fixing the turntable 82. Finally, the electric valve 5 is opened to complete the replacement of the filter block 85. When replacing the used filter block 85, the sealing door of the protective shell 812 is opened, and the screw 84 is rotated to release the screw 84 from fixing the shell 83, and the shell 83 is removed, and then the shell 83 with the new filter block 85 is installed on the turntable 82, and then the sealing door of the protective shell 812 is restored to its original position.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
