Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment equipment, in particular to a waste gas treatment device for hot melt pressure sensitive adhesive production. Background Art

[0002] Hot melt pressure sensitive adhesive is a special adhesive that can quickly adhere to the surface of various materials under slight pressure without the use of solvents or other auxiliary means for activation. It is mainly made of synthetic rubber, resin and rubber oil, etc., which are mixed and heated into a molten state, and then coated on substrates such as cotton paper, cloth or plastic film. Hot melt pressure sensitive adhesive has the advantage of low cost, but its viscosity is significantly affected by temperature. Hot melt pressure sensitive adhesive is the third generation product after solvent-based and emulsion-based pressure sensitive adhesives. Compared with the former two, hot melt pressure sensitive adhesive is solvent-free, more conducive to environmental protection and safe production, and has high production efficiency and relatively low production cost. Therefore, countries around the world are vigorously developing hot melt pressure sensitive adhesives. Hot melt pressure sensitive adhesives are mainly used for various types of carton sealing, box sealing, paper packaging, beverage bottle labels, sealing aluminum foil, waterproof coils, express delivery bills, flexible packaging and other packaging purposes, and are suitable for various materials.

[0003] A large amount of waste gas is generated during the production process of hot melt pressure-sensitive adhesive. The waste gas not only contains a large amount of smoke and floating matter, but also contains a large amount of heat. When hot melt pressure-sensitive adhesive manufacturers produce it, the waste gas generated in the production process is generally transported to the inside of a treatment box through an intake fan, and then the activated carbon adsorption material in the treatment box is used to adsorb and purify the harmful substances in the waste gas. However, when this treatment method is used, a large amount of smoke will adhere to the surface of the activated carbon adsorption material inside the treatment box after a long period of waste gas treatment, which will lead to a decrease in the absorption efficiency of adsorption materials such as activated carbon for harmful substances in the waste gas. In addition, the long-term high-temperature waste gas will continuously thermally shock the activated carbon filter material, which will also reduce the adsorption and purification effect of the activated carbon filter material on harmful substances in the waste gas. Therefore, those skilled in the art have proposed a waste gas treatment device for hot melt pressure-sensitive adhesive production to solve the above-mentioned technical problems.

[0019] Working principle: During the production process of hot melt pressure sensitive adhesive, the high-temperature exhaust gas generated is discharged through the conveying pipeline. At this time, the cooling and dilution mechanism is started. After the high-temperature exhaust gas enters the mixing and dilution flow channel of the exhaust gas exhaust channel through the conveying pipeline, part of the heat contained in the high-temperature exhaust gas is absorbed by the metal conduction plate in the mixing and dilution flow channel, so that the temperature of the high-temperature exhaust gas begins to drop, and the temperature of the metal conduction plate in the mixing and dilution flow channel begins to rise. After absorbing the heat in the high-temperature exhaust gas, the metal conduction plate evenly conducts it to various positions, and then the heat on the part of the metal conduction plate in the dispersion cavity is conducted through the cooperation of the air and the outer metal cover, so that the heat on the metal conduction plate is dissipated into the external environment, thereby completing The high-temperature exhaust gas is initially subjected to heat absorption and cooling treatment. At the same time, the exhaust fan on the outer metal cover is started, and the exhaust fan inputs air into the dispersion chamber. After the air enters the dispersion chamber, with the continuous delivery of the subsequent exhaust fan, the air in the dispersion chamber is accelerated to flow and enters the discharge transverse groove on the metal conduction plate through the diversion and guidance of the shielding diverter on the metal conduction plate. Then, the air entering the discharge transverse groove is discharged into the mixing and dilution flow channel through the discharge transverse groove on the metal conduction plate, thereby mixing with the high-temperature exhaust gas discharged into the mixing and dilution flow channel, diluting the harmful content in the high-temperature exhaust gas and cooling the high-temperature exhaust gas again. At the same time, with the continuous flow of air in the dispersion chamber, it is also synchronized. The metal conduction plate can conduct heat to the high-temperature exhaust gas in the dispersion chamber for cooling, thereby preventing the high-temperature exhaust gas from being directly discharged into the processing equipment and causing thermal shock damage to the equipment, thereby completing multiple cooling and dilution treatments of the high-temperature exhaust gas generated in the production process of the hot-melt pressure-sensitive adhesive; then the exhaust gas treated by the cooling and dilution treatment mechanism enters the first processing chamber in the processing box, at this time the circulating adsorption mechanism is started, first the circulating pump on the processing box is started, the circulating pump pumps the water in the storage chamber through the connecting pipe, and then transports it to the liquid separation seat on the top of the processing box through the connecting pipe, and then the water entering the liquid separation seat is diverted and then transported to the spray rows at various positions, and finally sprayed out by the spray row to become atomized water. and water curtain. When the high-temperature exhaust gas treated by the cooling and dilution mechanism enters the first treatment chamber, the high-temperature exhaust gas contacts the atomized water sprayed by the spray row and the water curtain. On the one hand, the heat in the high-temperature exhaust gas can be absorbed by the water, thereby performing the final cooling treatment on the exhaust gas. On the other hand, the contact between the exhaust gas and the water can adsorb the floating matter and smoke in the exhaust gas, thereby completing the pretreatment operation before the exhaust gas is purified. Then, the water adsorbing the floating matter and smoke in the exhaust gas falls down and is filtered through a plurality of mesh filter plates. After that, the filtered water falls into the storage chamber for subsequent recycling and reuse, thereby completing the cyclic adsorption treatment of the exhaust gas.After that, the exhaust gas treated by the circulating adsorption mechanism enters the second treatment chamber of the treatment box. At this time, the multiple treatment mechanisms are started, and the exhaust gas entering the second treatment chamber first passes through the filter cotton plate on the mounting seat 1 to perform multiple filtrations on the smoke and floating matter remaining in the exhaust gas. After the filter cotton plate has been used for a certain period of time, the staff can open the inspection window 1 on the treatment box, and then pull out the filter cotton plate in the plug-in slot 1, clean the smoke and floating matter collected and filtered on the filter cotton plate, and then reset it to ensure the filtering effect of the exhaust gas. Then, the exhaust gas filtered by the filter cotton plate enters the bottom position of the connecting seat. At this time, the high-voltage power supply on the treatment box is connected to the bottom of the connecting seat. The conductive connecting rod and the electrode ring rod at the top are energized, and the discharge of the electrode ring rod forms a high-intensity electric field at the position of the electrode ring rod. Under the action of this electric field, the smoke and floating matter in the exhaust gas entering the electric field collide with the free electrons and ions in the electric field, thereby being charged. Under the action of the electric field force, these charged particles move toward the electrode sheet with the opposite charge. Since the surface area of ​​the electrode ring rod is relatively large, the charged particles in the exhaust gas will be adsorbed on the surface of the electrode sheet, and then the air with smoke and floating matter removed will enter the next processing chamber through the guide groove on the electrode sheet for processing. After the smoke and floating matter on the electrode sheet are collected to a certain extent, the staff can use the processing box The control panel on the control panel controls the high-voltage power supply to cut off the power. After the power is cut off, the electrode ring rod accessories have no power support and thus cannot form a high-voltage electric field. After the power is cut off, the smoke and floating matter adsorbed on the electrode sheet will fall off and enter the collection drawer for centralized collection. After a certain degree of collection in the collection drawer, the staff can pull out the collection drawer on the processing box, and then centrally treat the smoke and floating matter collected in the collection drawer, so as to complete the multiple treatment of the exhaust gas; the exhaust gas treated by the multiple treatment mechanisms enters the third treatment chamber in the processing box, at which time the purification and emission mechanism starts, and the suction fan on the processing box operates, and the suction fan draws the air in the processing chamber, As a result, the waste gas entering the third treatment chamber is affected by the negative pressure and flows into the activated carbon filter plate on the second mounting seat. When the waste gas passes through the activated carbon filter plate, the activated carbon adsorption material in the activated carbon filter plate purifies the harmful substances in the waste gas. Finally, after the purification treatment, it is discharged through the exhaust duct after being guided by the suction fan. After the activated carbon filter plate has been used for a certain period of time, the filtering and purification effect of the activated carbon filter plate decreases. At this time, the staff can open the inspection window 2 on the treatment box, then pull out the activated carbon filter plate in the plug-in slot 2 and replace it with a new activated carbon filter plate before purifying the waste gas, thereby ensuring the purification effect of the waste gas, thereby completing the purification and emission treatment of the waste gas. ;

[0020] The present invention provides a waste gas treatment device for hot melt pressure sensitive adhesive production. It has the following beneficial effects:

[0021] 1. The present invention adds and sets a cooling and dilution mechanism. On the one hand, by means of metal conduction, the heat in the exhaust gas can be efficiently conducted away to achieve cooling. At the same time, air flow is used to assist in driving heat dissipation. The exhaust gas temperature is effectively reduced by two prongs. On the other hand, by introducing external air to mix with the exhaust gas, the exhaust gas is not only diluted, but also its temperature is further reduced, which fundamentally prevents the high temperature of the exhaust gas from causing thermal shock to the inside of the treatment equipment. In this way, the normal operation of the treatment equipment is greatly guaranteed, so that it can stably and efficiently carry out subsequent treatment of the exhaust gas, reduce the risk of equipment failure caused by high temperature, extend the service life of the equipment, and ensure the continuity and reliability of the entire exhaust gas treatment process.

[0022] 2. The present invention increases and sets a circulating adsorption mechanism. When treating the waste gas treated by the cooling and dilution mechanism, on the one hand, the mechanism can effectively capture and remove smoke and floating objects contained in the waste gas with the help of water mist and water curtain, thereby ensuring the cleanliness of subsequent treatment of the waste gas. At the same time, water recycling is achieved through filtration, which greatly reduces the waste of water resources and conforms to the concepts of environmental protection and resource conservation. On the other hand, while playing a purification role, the water mist and water curtain can also cool the waste gas again, further optimizing the state of the waste gas and creating good conditions for subsequent more in-depth treatment links. This treatment method not only helps to improve the treatment efficiency and quality of the entire waste gas treatment system, but also can reduce equipment loss to a certain extent, reduce operating costs, and make waste gas treatment more green, efficient and sustainable.

[0023] 3. The present invention adds and sets multiple processing mechanisms. After the exhaust gas passes through the circulation processing mechanism, the multiple processing mechanisms begin to play a role. First, the filter panel is used to filter and remove the remaining smoke and floating matter in the exhaust gas again, further improving the purity of the exhaust gas. Then, the high-voltage electric field and the electrode sheet cooperate with each other to perform the final deep treatment on the remaining smoke and floating matter in the exhaust gas. It can remove those fine and stubborn impurities very accurately and efficiently, so that the exhaust gas reaches a higher cleanliness standard, thereby greatly ensuring the exhaust gas emission quality and effectively reducing the pollution impact on the surrounding environment. At the same time, it is also beneficial for enterprises to better meet environmental protection requirements, promote green production, and achieve sustainable development.

[0024] 4. The present invention increases and sets a purification and emission mechanism. Under the guidance of the suction fan, the exhaust gas is filtered through an activated carbon filter plate. The activated carbon filter plate can accurately capture various harmful substances remaining in the exhaust gas by virtue of its own developed pore structure and strong adsorption performance, and realize deep purification. This treatment method not only greatly improves the emission quality of the exhaust gas, making it meet more stringent environmental emission standards, effectively avoiding pollution to the surrounding atmospheric environment, but also helps enterprises establish a good environmental image. While fulfilling their environmental protection responsibilities, they also contribute to the sustainable development of the regional ecological environment and ensure the harmonious coexistence of production and the environment.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Please refer to the attached Figure 1 - Attachment Figure 3 The embodiment of the present invention provides an exhaust gas treatment device for hot melt pressure sensitive adhesive production, comprising a treatment box 1, which is a structural component of the overall device and is used to assemble and carry various treatment mechanisms and their subordinate structural components; two partitions 18, which are equidistantly arranged inside the treatment box 1, and divide the interior of the treatment box 1 into three interconnected treatment chambers 15 in sequence at equidistant intervals;

[0036] Please refer to the attached Figure 4 - Attachment Figure 5 , a cooling and diluting mechanism, which is arranged in the middle of one side of the processing box 1, and is used to cool and dilute the waste gas discharged from the production of hot melt pressure sensitive adhesive;

[0037] The cooling and dilution mechanism includes an exhaust duct 2. The exhaust duct 2 is arranged in the middle of one side of the treatment box 1. A mixing and dilution flow channel 25 is arranged inside the exhaust duct 2, and one end of the mixing and dilution flow channel 25 is connected to the interior of the first treatment chamber 15. A jacket metal cover 4 is fixedly connected to the middle of the outer wall of the exhaust duct 2. A plurality of metal conduction plates 28 are fixedly connected to the inner wall of the exhaust duct 2 at equal intervals, and the outer ends of the metal conduction plates 28 penetrate the exhaust duct 2 and extend into the jacket metal cover 4.

[0038] When the cooling and dilution mechanism is started, after the high-temperature exhaust gas enters the mixing and dilution flow channel 25 of the exhaust gas exhaust channel 2 through the delivery pipe, part of the heat contained in the high-temperature exhaust gas is absorbed by the metal conduction plate 28 in the mixing and dilution flow channel 25, so that the temperature of the high-temperature exhaust gas begins to drop, and the temperature of the metal conduction plate 28 in the mixing and dilution flow channel 25 begins to rise. After absorbing the heat in the high-temperature exhaust gas, the metal conduction plate 28 evenly conducts it to various positions, and then the heat on the part of the metal conduction plate 28 in the dispersion chamber 26 is conducted through the cooperation of the air and the outer metal cover 4, so that the heat on the metal conduction plate 28 is dissipated into the external environment, thereby completing the preliminary heat absorption and cooling treatment of the high-temperature exhaust gas.

[0039] The cooling and dilution mechanism also includes a shielding and diverting plate 30, and a shielding and diverting plate 30 is fixedly connected to one side of the middle of the upper and lower ends of the metal conduction plate 28. A discharge transverse groove 29 is opened in the middle of the upper and lower ends of the metal conduction plate 28. A discharge transverse groove 27 is opened in the middle of the upper and lower ends of one side of the metal conduction plate 28, and the interior of the discharge transverse groove 27 is respectively connected with the interior of the corresponding discharge transverse groove 29 on the same side. A dispersion chamber 26 is formed between the outer wall of the exhaust gas exhaust duct 2 and the inner wall of the outer metal cover 4. An exhaust fan 3 is arranged in the middle of one side of the upper and lower ends of the outer metal cover 4, and the exhaust outlet of the exhaust fan 3 is connected with the interior of the dispersion chamber 26.

[0040] At the same time, the exhaust fan 3 on the outer metal cover 4 is started, and the exhaust fan 3 inputs air into the dispersion chamber 26. After the air enters the dispersion chamber 26, with the continuous delivery of the subsequent exhaust fan 3, the air in the dispersion chamber 26 is accelerated to flow and enters the discharge groove 29 on the metal conduction plate 28 through the diversion and guidance of the shielding diverter plate 30 on the metal conduction plate 28. Then, the air entering the discharge groove 29 is discharged into the mixing and dilution flow channel 25 through the discharge groove 27 on the metal conduction plate 28, thereby mixing with the high-temperature exhaust gas discharged into the mixing and dilution flow channel 25, diluting the harmful content in the high-temperature exhaust gas and cooling the high-temperature exhaust gas again.

[0041] At the same time, as the air in the dispersion chamber 26 continues to flow, the heat in the high-temperature exhaust gas in the dispersion chamber 26 conducted by the metal conduction plate 28 can be cooled synchronously, thereby avoiding the thermal shock damage to the equipment caused by the high-temperature exhaust gas directly discharged into the processing equipment, thereby completing the multiple cooling and dilution treatments of the high-temperature exhaust gas generated in the production process of the hot melt pressure-sensitive adhesive.

[0042] Please refer to the attached Figure 3 , a circulating adsorption mechanism, which is arranged in the first processing chamber 15, and is used to cool and adsorb the waste gas after the treatment by the cooling and dilution mechanism by means of liquefied water mist and liquefied water curtain;

[0043] The circulating adsorption mechanism includes a spray row 24. A plurality of spray rows 24 are equidistantly and staggeredly arranged on the top of the inner wall of the first processing chamber 15, and the spray rows 24 are staggered by atomizing spray rows and water curtain spray rows. A plurality of mesh filter plates 16 are equidistantly and fixedly connected to the middle and lower parts of the inner side of the first processing chamber 15, and the apertures of the mesh filter plates 16 decrease successively from top to bottom. A storage chamber 17 is arranged at the bottom of the inner side of the first processing chamber 15. A liquid separator seat 5 is arranged in the middle of one side of the top of the processing box 1, and the interior of the liquid separator seat 5 is connected with the liquid inlet of the corresponding spray row 24. A circulating pump 14 is arranged on one side of the middle and lower part of the rear end of the processing box 1, and the liquid inlet of the circulating pump 14 is connected with the bottom of the storage chamber 17 through a connecting pipe, and the liquid outlet of the circulating pump 14 is connected with the interior of the liquid separator seat 5 through a connecting pipe.

[0044] When the circulating adsorption mechanism is started, the circulating pump 14 on the processing box 1 is started first. The circulating pump 14 pumps the water in the storage chamber 17 through the connecting pipe, and then transports it to the liquid separation seat 5 on the top of the processing box 1 through the connecting pipe. Thereafter, the water entering the liquid separation seat 5 is diverted and then transported to the spray rows 24 at various positions, and finally sprayed out by the spray row 24 to become atomized water and a water curtain.

[0045] When the high-temperature exhaust gas treated by the cooling and dilution mechanism enters the first treatment chamber 15, the high-temperature exhaust gas contacts the atomized water sprayed by the spray row 24 and the water curtain. On the one hand, the heat in the high-temperature exhaust gas can be absorbed by water, thereby performing the final cooling treatment on the exhaust gas. On the other hand, the floating matter and smoke in the exhaust gas can be adsorbed through the contact between the exhaust gas and water, thereby completing the pretreatment operation before purifying the exhaust gas. Then, the water that adsorbs the floating matter and smoke in the exhaust gas falls and is filtered through a plurality of mesh filter plates 16. After that, the filtered water falls into the storage chamber 17 for subsequent circulation and reuse, thereby completing the cyclic adsorption treatment of the exhaust gas.

[0046] Please refer to the attached Figure 6 - Attachment Figure 7 , a multiple treatment mechanism, which is arranged in the second treatment chamber 15, and is used to perform multiple treatments on the waste gas treated by the circulating adsorption mechanism;

[0047] The multiple processing mechanism includes a mounting seat 19, a mounting seat 19 is arranged on one side of the middle of the second processing chamber 15, a plurality of plug-in slots 31 are equidistantly provided inside the mounting seat 19, filter cotton plates 32 are slidably connected inside the plug-in slots 31, and an inspection window 6 is arranged on one side of the middle of the top of the processing box 1.

[0048] When the multiple processing mechanism is started, the exhaust gas entering the second processing chamber 15 is first filtered multiple times by the filter cotton plate 32 on the mounting seat 19 to remove the smoke and floating objects remaining in the exhaust gas. After the filter cotton plate 32 has been used for a certain period of time, the staff can open the inspection window 6 on the processing box 1, and then pull out the filter cotton plate 32 in the plug-in slot 31, clean the smoke and floating objects collected and filtered on the filter cotton plate 32, and then reset it, so as to ensure the filtering effect of the exhaust gas.

[0049] The multi-processing mechanism also includes a connecting seat 23. A connecting seat 23 is arranged on one side of the middle of the top end of the second processing chamber 15. Conductive connecting rods 33 are fixedly connected at the four corners of the bottom of the connecting seat 23. Multiple electrode ring rods 22 are equidistantly arranged on the conductive connecting rods 33. Multiple electrode sheets 20 are equidistantly arranged in the middle of the bottom end of the connecting seat 23. Multiple groups of guide grooves 34 are equidistantly provided on the electrode sheets 20. A high-voltage power supply 7 is arranged on one side of the middle of the top end of the processing box 1, and the high-voltage power supply 7 is electrically connected to the connecting seat 23, the conductive connecting rod 33 and the electrode sheets 20. A collection drawer 12 is arranged on one side of the bottom end of the front side of the processing box 1, and a control panel 11 is arranged on one side of the upper and middle part of the front side of the processing box 1, and the control panel 11 is electrically connected to the high-voltage power supply 7.

[0050] Then the exhaust gas after being filtered by the filter cotton plate 32 enters the bottom position of the connecting seat 23. At this time, the high-voltage power supply 7 on the processing box 1 energizes the conductive connecting rod 33 and the electrode ring rod 22 at the bottom of the connecting seat 23. The discharge of the electrode ring rod 22 forms a high-intensity electric field at the position of the electrode ring rod 22. Under the action of this electric field, the smoke and floating matter in the exhaust gas entering the electric field collide with the free electrons and ions in the electric field, thereby carrying an electric charge. These charged particles move toward the electrode sheet 20 with the opposite charge under the action of the electric field force. Since the surface area of ​​the electrode ring rod 22 is relatively large, the charged particles in the exhaust gas will be adsorbed on the surface of the electrode sheet 20, and then the air without smoke and floating matter will pass through the guide groove 34 on the electrode sheet 20 into the next processing chamber 15 for treatment.

[0051] After the smoke and floating matter on the electrode sheet 20 are collected to a certain extent, the staff can control the high-voltage power supply 7 to cut off the power through the control panel 11 on the processing box 1. After the power is cut off, the electrode ring rod 22 accessories are no longer supported by electricity and thus cannot form a high-voltage electric field. After the power is cut off, the smoke and floating matter adsorbed on the electrode sheet 20 will fall off and enter the collection drawer 12 for centralized collection. After the collection in the collection drawer 12 reaches a certain extent, the staff can pull out the collection drawer 12 on the processing box 1, and then centrally process the smoke and floating matter collected in the collection drawer 12, thereby completing multiple treatments of the exhaust gas.

[0052] Please refer to the attached Figure 8 , a purification and emission mechanism is arranged in the third processing chamber 15, and is used for the final purification and emission treatment of the waste gas after the multiple processing mechanisms have finished the treatment.

[0053] The purification and emission mechanism also includes an intake fan 9. An intake fan 9 is arranged in the middle part of one side of the processing box 1 away from the exhaust duct 2, and the air inlet of the intake fan 9 is connected with the interior of the third processing chamber 15. An exhaust duct 10 is arranged on the exhaust port of the intake fan 9, and a foreign matter protection cover 13 is arranged on the end of the exhaust duct 10 away from the intake fan 9.

[0054] When the purification and emission mechanism is started, the suction fan 9 on the treatment box 1 operates, and the suction fan 9 draws the air in the treatment chamber 15, so that the exhaust gas entering the third treatment chamber 15 flows under the influence of negative pressure and enters the activated carbon filter plate 35 on the mounting seat 21. When the exhaust gas passes through the activated carbon filter plate 35, the activated carbon adsorption material in the activated carbon filter plate 35 purifies the harmful substances in the exhaust gas. Finally, after purification, the exhaust gas is discharged through the exhaust duct 10 under the guidance of the suction fan 9.

[0055] The purification and discharge mechanism includes a mounting seat 21, and a mounting seat 21 is arranged inside the third processing chamber 15. A plurality of plug-in grooves 36 are equidistantly provided inside the mounting seat 21, and activated carbon filter plates 35 are slidably connected in the plug-in grooves 36. An inspection window 8 is arranged in the middle of the top side of the processing box 1 away from the liquid separation seat 5.

[0056] After the activated carbon filter plate 35 has been used for a certain period of time, the filtering and purification effect of the activated carbon filter plate 35 decreases. At this time, the staff can open the inspection window 2 8 on the processing box 1, and then pull out the activated carbon filter plate 35 in the plug-in slot 2 36 and replace it with a new activated carbon filter plate 35 before purifying the exhaust gas, thereby ensuring the purification effect of the exhaust gas and completing the purification and emission treatment of the exhaust gas.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
