Description

Technical Field

[0001] The present invention relates to the technical field of waste gas purification, and particularly relates to an organic waste gas collection and purification device for the production of environment-friendly water-based ink. Background Art

[0002] As a relatively environment-friendly printing material, water-based ink has been widely used in the fields of packaging printing, publishing printing, etc. in recent years. Compared with traditional solvent-based ink, water-based ink uses water as a solvent or diluent, greatly reducing the emission of volatile organic compounds (VOCs). However, in the production process of water-based ink, such as batching, stirring, grinding, blending and other processes, a certain amount of organic waste gas will still be inevitably generated. These waste gases contain various pollutants, such as volatile organic compounds such as alcohols, esters, benzene series, as well as ink particles, dust, etc. If these waste gases are directly discharged into the atmosphere without effective treatment, it will have a serious impact on the surrounding air quality, causing environmental problems such as haze and photochemical smog, and at the same time will also endanger the health of the human respiratory system, nervous system, etc.

[0003] Chinese Patent Publication No. CN218130879U discloses an organic waste gas collection and purification device for the production of environment-friendly water-based ink, including a purification box. Connecting cylinders are respectively connected to both ends of the purification box. Clamping strips are respectively arranged at one end of the inner wall of the purification box. An activated carbon filter plate is slidably connected inside the clamping strips. First partitions are respectively arranged inside the purification box. The filtered waste gas drifts to the bottom of the nozzle. The filtered waste gas drifts to the bottom of the nozzle. By the operation of the water pump, the water on one side of the first partition is pumped out, so that the water is transported to the inside of the water receiving plate through a water pipe and then sprayed out by the nozzle, thereby filtering out the water-soluble particles in the waste gas. Then the waste gas drifts to the surface of the air-permeable plate. Through the irradiation of the ultraviolet lamp on the air-permeable plate, a photocatalytic reaction is carried out to purify the waste gas. Through such diverse treatments, the waste gas can be comprehensively purified and filtered, increasing the waste gas purification effect; However, the above device has a too simple structure during use and cannot automatically adjust the purification effect according to the particle content in the waste gas.

[0019] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0020] Example 1, as shown in Figure 1-3As shown in the figure, an environmentally friendly water-based ink production organic waste gas collection and purification device includes a housing 1. A spray component 2 is arranged on the lower side inside the housing 1. A cleaning component 3 is arranged above the spray component 2. A baffle component 4 is arranged above the cleaning component 3. Adjusting components 5 are arranged on the left and right sides of the baffle component 4. A filtering component 6 is arranged above the baffle component 4. An ultraviolet purification component 7 is arranged above the filtering component 6.

[0021] Therefore, in this solution, the ink molecules, water-soluble pollutants and large and small particles in the waste gas are first filtered and removed by the spray component 2 and the filtering component 6, laying the foundation for subsequent treatment. When the waste gas contains a large amount of particles, the cooperation of the cleaning component 3 and the adjusting component 5 can not only increase the inclination angle of the baffle component 4 to strengthen particle separation, but also move the ultraviolet purification component 7 to enhance the irradiation effect, so as to automatically adjust the purification effect according to the particle content in the waste gas, enabling the equipment to adapt to waste gases with different concentrations of pollutants, improving the treatment efficiency and stability, comprehensively purifying the waste gas, ensuring the purification effect and improving the energy utilization efficiency.

[0022] Embodiment 2. On the basis of Embodiment 1, this embodiment is to achieve the effect of automatically adjusting the purification ability according to the particle content in the waste gas.

[0023] Refer to Figure 1-10 , the housing 1 includes a base 11. A drain valve is arranged at the bottom of the base 11. An air inlet 12 is fixedly connected to the outer surface of the base 11. A fixed column 13 is fixedly connected to the upper end of the base 11. A fixed box 14 is fixedly connected to the upper end of the fixed column 13. An air outlet 15 is fixedly connected to the upper end of the fixed box 14. A connecting pipe 16 is fixedly connected to the lower end of the fixed box 14. The waste gas can enter the fixed box 14 from the base 11 through the connecting pipe 16.

[0024] Refer to Figure 4-5 , the spray component 2 includes a spray pipe 21 fixedly installed on the upper side of the base 11. A plurality of nozzles are arranged at the lower end of the spray pipe 21. The right end of the spray pipe 21 is connected to an external water tank. A metal filter plate 22 is arranged on the lower side of the spray pipe 21. The bottom wall of the inner surface of the base 11 is rotatably connected to a rotating shaft 23. A wind cup 24 is fixedly connected to the outer surface of the rotating shaft 23. A cleaning brush 25 is fixedly connected to the outer surface of the rotating shaft 23 and above the wind cup 24. The upper end of the cleaning brush 25 is rotatably connected to the metal filter plate 22.

[0025] The above spray pipe 21 is a conventional technical means in the prior art, and its working principle is: the water pump pumps the absorption liquid in the water tank into the pipeline, and after pressurization, it is transported to the nozzles at the lower end of the spray pipe 21. The nozzles spray the absorption liquid into fine mist droplets or liquid curtains. The waste gas enters from the lower part of the device and fully contacts the falling absorption liquid during the rising process. The pollutants in the waste gas undergo physical dissolution or chemical reactions with the absorption liquid, and thus are absorbed and removed.

[0026] The rotation of the wind cup 24 depends on the self-flow of the waste gas, realizing the full mixing of the spraying liquid and the air flow without additional power, saving energy and having a good mixing effect. Moreover, when the wind cup 24 rotates, it will drive the cleaning brush 25 to rotate synchronously, so that the cleaning brush 25 can clean the metal filter plate 22.

[0027] The metal filter plate 22 can effectively intercept larger particulate impurities in the waste gas, reducing the burden on the subsequent treatment structure.

[0028] Furthermore, the waste gas enters the base 11 from the air inlet 12. The waste gas with a certain flow rate drives the wind cup 24 to rotate. The wind cup 24 rotates to break up the spraying liquid into fine droplets, making the droplets fully contact with the waste gas. Some pollutants such as ink particles contained in the waste gas will dissolve in the spraying liquid, and some particulate pollutants will be captured after colliding with the droplets. Subsequently, the waste gas will pass through the metal filter plate 22, and larger ink agglomerated particles, impurities, etc. in the waste gas will be intercepted, thereby removing larger-sized ink agglomerated particles, solid impurities, etc. in the waste gas. Synchronously, the wind cup 24 can drive the cleaning brush 25 to clean the metal filter plate 22 synchronously, preventing the metal filter plate 22 from being blocked after long-term use.

[0029] Refer to Figure 6-8 , the cleaning assembly 3 includes an annular dust collection groove 31 slidably connected to the lower end of the fixed box 14. A plurality of first springs 32 are fixedly connected to the lower end of the annular dust collection groove 31. Connecting seats 33 are fixedly connected to the left and right sides of the annular dust collection groove 31. Connecting frames 34 are fixedly connected to the upper ends of the two connecting seats 33. A water spraying pipe 35 is arranged on the outer surface of the fixed box 14 and on the left side of the connecting pipe 16. A valve 351 is arranged at the left end of the water spraying pipe 35, and the left end of the valve 351 is connected to an external water source.

[0030] The above-mentioned annular dust collection groove 31 is made of polypropylene, with a light weight, which can reduce the self-weight of the annular dust collection groove 31 and make it more sensitive to the change in the weight of water droplets. At the same time, it has good toughness and chemical corrosion resistance, and is not easily damaged even when in long-term contact with water droplets containing impurities.

[0031] The highest position of the annular dust collection groove 31, which is also the initial position, is flush with the bottom of the fixed box 14, facilitating the smooth sliding of the dripping liquid above into the annular dust collection groove 31.

[0032] A pulling block 36 is slidably connected to the inner surface of the valve 351. The lower end of the pulling block 36 is fixedly connected to the left connecting frame 34. A limiting block 37 is fixedly connected to the upper end of the pulling block 36. A second spring 38 is fixedly connected to the upper end of the limiting block 37. A stop block 39 is fixedly connected to the upper end of the second spring 38. A water inlet 310 is arranged at the connection between the valve 351 and the water spraying pipe 35, and the outer surface of the stop block 39 is slidably connected to the water inlet 310.

[0033] A drain valve is provided at the rear of the annular dust collection tank 31, and the second spring 38 can reset the stopper 39 to block the water inlet 310.

[0034] When the weight of the annular dust collection tank 31 reaches a certain level, it will slowly sink and squeeze the first spring 32, driving the connecting seat 33 and the connecting frame 34 to descend together, so that the connecting frame 34 drives the pulling block 36 to descend. The pulling block 36 pulls the limiting block 37, the second spring 38 and the stopper 39 to descend. The stopper 39 moves and leaves the position where it completely fits with the water inlet 310, and water will flow into the spray pipe 35 from the water inlet 310 and then flow into the annular dust collection tank 31, so that the water flow flushes the annular dust collection tank 31.

[0035] Refer to Figure 9 , the baffle assembly 4 includes four second rotating shafts 41 rotatably connected to the inner surface of the fixed box 14. Baffle plates 42 are fixedly connected to the outer surfaces of the four second rotating shafts 41. The positions of the four second rotating shafts 41 and the baffle plates 42 are respectively located at the four sides of the inner surface of the fixed box 14.

[0036] The above-mentioned second rotating shafts 41 and the baffle plates 42 are vertically distributed on the four surfaces of the inner surface of the fixed box 14, avoiding the problem that part of the waste gas drifts away and leaks from the connection between one of the second rotating shafts 41 and the fixed box 14. Even if the waste gas rises and leaks from one direction, there are still three other directions, enabling the waste gas to be fully treated and ensuring the effectiveness and stability of the purification device.

[0037] Furthermore, when the sprayed waste gas enters the fixed box 14 from the connecting pipe 16 and then continues to rise and hits the baffle plate 42, the direction of its airflow will suddenly change. Due to inertia, the particles in the waste gas will continue to move in the original direction and hit the baffle plate 42. After the particles collide with each other, they are more likely to aggregate into larger liquid beads and slide down to the annular dust collection tank 31 under the action of gravity. When the amount of particles in the waste gas is small, the annular dust collection tank 31 remains stationary and the waste gas can be normally filtered and purified. When the amount of particles in the waste gas is large, the annular dust collection tank 31 will quickly accumulate weight, causing the annular dust collection tank 31 to descend and driving the spray pipe 35 to start spraying water. When the spray pipe 35 starts spraying water, the weight of the annular dust collection tank 31 will increase rapidly.

[0038] Wherein, a sealing ring is provided at the connection between the annular dust collection tank 31 and the fixed box 14, and there will be no water leakage.

[0039] Refer to Figure 7 And Figure 9, the adjusting assembly 5 includes a first fixing plate 51 fixedly connected to the left side of the fixed box 14. The upper end of the first fixing plate 51 is fixedly connected to a first airbag 52. The upper end of the connecting frame 34 is fixedly connected to a pressing plate 53. The lower end of the pressing plate 53 is fixedly connected to the first airbag 52. Two second fixing plates 54 are fixedly connected to the left side of the inner surface of the fixed box 14. The two second fixing plates 54 are respectively located on two adjacent inner walls of the inner surface of the fixed box 14 and are distributed vertically. The right end of the first airbag 52 is fixedly connected to a first air pipe 55. Both ends of the first air pipe 55 are fixedly connected to second airbags 56. The lower ends of the two second airbags 56 are fixedly connected to the two second fixing plates 54. The upper ends of the two second airbags 56 are movably connected to the two baffle plates 42.

[0040] The four second airbags 56 are respectively located at the lower ends of the four baffle plates 42, and the specific positions are in a circular array, respectively close to the four surfaces of the inner surface of the fixed box 14.

[0041] Furthermore, when the weight of the annular dust collection groove 31 increases rapidly, it will drive the pressing plates 53 on both sides to squeeze the first airbag 52, so that the two first airbags 52 simultaneously inflate the four second airbags 56 inside. The second airbags 56 expand and thus push up the baffle plates 42 in contact with them, making the inclination angle of the baffle plates 42 larger. After the inclination angle becomes larger, the degree of direction change of the waste gas when passing through the baffle plates 42 is more significant. Due to inertia, the particles will continue to move along the original direction, which increases the probability of the particles hitting the baffle plates 42. After more particles hit the baffle plates 42, they collide with each other and aggregate into larger liquid beads, which are more likely to slide down to the annular dust collection groove 31 under the action of gravity, thereby improving the separation efficiency of ink particles, dust, etc. in the waste gas, reducing the discharge of particles with the purified waste gas. At the same time, when the liquid beads slide down along the surface of the baffle plates 42 under the action of gravity, the larger the inclination angle, the greater the component force of gravity along the surface of the baffle plates 42 downward, the stronger the driving force for the liquid beads to slide down, and the faster the sliding speed. This can effectively reduce the residence time of the liquid beads on the baffle plates 42 and reduce the possibility of being re-entrained by the upward airflow, ensuring the stability of the separation effect.

[0042] Refer to Figure 3 , a first filter plate 61 is arranged on the inner surface of the fixed box 14. A second filter plate 62 is arranged above the first filter plate 61. A third filter plate 63 is arranged above the second filter plate 62.

[0043] Furthermore, the first filter plate 61 is a coarse fiber filter layer, which can remove larger particle sizes that still remain after the previous steps of treatment, such as slightly aggregated particles and fibrous impurities that have not been completely removed. The second filter plate 62 is an activated carbon adsorption filter layer, which mainly removes volatile organic compounds in the waste gas, such as benzene series, esters, ketones, etc., as well as various odor substances. The filter plate three 63 is a high-efficiency fiberglass filter layer that removes residual fine particles in the exhaust gas, such as nanoscale organic aerosols and fine dust.

[0044] Refer to Figure 7 And Figure 10 , the ultraviolet purification component 7 includes a support plate 71 fixedly connected to the inner surface of the fixed box 14. Three ultraviolet lamps 72 are arranged at the upper end of the support plate 71. The upper ends of the two air bags one 52 are fixedly connected with two air pipes two 73 respectively. The mutually close ends of the two air pipes two 73 are fixedly connected with an air bag three 74.

[0045] The lower ends of the two air bags three 74 are jointly fixedly connected to the support plate 71, and the upper ends of the two air bags three 74 are jointly fixedly connected with an ultraviolet filter 75.

[0046] The ultraviolet lamp 72 can deeply purify the volatile organic compounds VOCs remaining after the previous multi-layer filtration treatment, further reduce the concentration of organic pollutants, and ensure the up-to-standard discharge of the exhaust gas.

[0047] When the particle content in the exhaust gas is low and the high-intensity ultraviolet lamp 72 is not required for irradiation, the ultraviolet filter 75 can block part of the ultraviolet rays and appropriately reduce the irradiation intensity of the ultraviolet lamp 72 on the exhaust gas. This helps to avoid excessive ultraviolet energy consumption and extend the service life of the ultraviolet lamp 72. When there are a large number of particles in the exhaust gas, the annular dust collection groove 31 increases in weight due to collecting particles, triggering the pressing plate 53 to squeeze the air bag one 52. The air bag one 52 can inflate the air bag two 56 while also inflating the air bag three 74. The inflation of the air bag three 74 can drive the ultraviolet filter 75 to lift up, causing the surface of the air pipe two 73 to lose the shield, enhancing the ultraviolet irradiation effect. Finally, the purified gas is discharged from the air outlet 15.

[0048] The overall realization of the adaptive adjustment function of the device dynamically adjusts the purification method according to the concentration of pollutants in the exhaust gas. When there are more particulate pollutants, it means that there may also be relatively more organic pollutants. At this time, enhancing the ultraviolet irradiation intensity can more effectively decompose organic pollutants, improve the purification effect, and ensure the up-to-standard discharge of the exhaust gas under complex working conditions.

[0049] It should be added that in the initial stage of the device operation, each structure has effectively purified the exhaust gas, and can remove most of the larger particles and part of the water-soluble pollutants. As the weight of the annular dust collection groove 31 increases, the changes in each structure will improve the subsequent exhaust gas treatment effect, but the previous purification foundation ensures that the initial exhaust gas can also be well purified. Moreover, the entire purification process is a continuous dynamic adjustment process. Generally speaking, the device can maintain a relatively stable and high purification efficiency for the exhaust gas entering at different stages.

[0050] Therefore, this solution preliminarily sprays the exhaust gas through the spray component 2, and then allows the water-saturated exhaust gas to collide with the baffle plate 42 to separate and condense into liquid droplets and slide down to the annular dust collecting trough 31. When the exhaust gas contains a large number of particles, the weight of the annular dust collecting trough 31 can be used to simultaneously complete the self-cleaning of the annular dust collecting trough 31, and adjust the inclination angle of the four baffle plates 42 and the shielding area of ​​the ultraviolet filter 75 on the ultraviolet lamp 72 to enhance the overall purification and filtering effect of the exhaust gas, and automatically adjust the purification strategy according to the actual situation of the exhaust gas.

[0051] It should be noted that the specific installation method of the spray pipe 21 and the ultraviolet lamp 72, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0052] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
