Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, in particular to a drying waste gas treatment device for fluff decorative cloth. Background Art

[0002] The gases generated during the drying process of printed fabrics mainly include water vapor, particulate matter, and volatile organic compounds. These gases are harmful to human health and the environment. VOCs released during the drying process, such as benzene, aldehydes, ketones, etc., are highly irritating. Long-term inhalation can damage the respiratory mucosa, causing symptoms such as coughing, chest tightness, and shortness of breath. In severe cases, it may lead to respiratory diseases. If the exhaust gas generated during the drying process is directly discharged into the atmosphere without treatment, it will cause air pollution and affect air quality.

[0003] Among them, the gases generated during the drying process of printed fabrics mainly include water vapor, particulate matter, and volatile organic compounds. The generated water vapor also moves with harmful substances. Due to the presence of water vapor, the complexity of waste gas treatment may be increased. Although water vapor itself is harmless, its high humidity environment may affect the efficiency of certain waste gas treatment equipment. In some cases, water vapor may even dissolve or carry a certain amount of harmful waste gas. Therefore, it is necessary to separate the generated water vapor. The current separation method is to use condensation method, which reduces the temperature of the waste gas and condenses the water vapor and other components into liquid, so as to achieve recycling and reuse. In this way, the gas passes through the condenser, and the cooling medium in the condenser exchanges heat with the waste gas, so that the temperature of the waste gas drops rapidly. During the heat exchange process, the degree of contact between the cooling medium and the waste gas is limited, and the local waste gas cannot directly contact the cooling medium.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments 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.

[0031] See also Figure 1-Figure 7 The present invention provides a technical solution: the fluff decorative cloth, as the name implies, has a layer of fine fluff on its surface. The presence of these fluffs has a significant effect on the physical and chemical properties of the decorative cloth. During the printing process, ink and solvent will be applied to the decorative cloth. For ordinary smooth-surface decorative cloth, the adsorption of ink and solvent mainly occurs on the surface of the cloth, and the adsorption area is relatively limited. However, for fluff decorative cloth, the situation is completely different. Due to the presence of fluff, the surface of the decorative cloth becomes uneven, which greatly increases the adsorption area of ​​ink and solvent. Drying is an important step after printing, which aims to remove excess ink and solvent on the decorative cloth, and at the same time remove the moisture in the fluff decorative cloth, so that it is dry and meets the use requirements. In this process, the volatile components in the ink and solvent will gradually evaporate to form waste gas. Therefore, an improvement is proposed, and a drying waste gas treatment device for fluff decorative cloth is proposed, including a transmission pipe 1 and a condenser pipe 2. The condenser pipe 2 is used to cover the transmission pipe 1, wherein the temperature of the water vapor in the transmission pipe 1 is reduced after the covering. The outer side of the condenser pipe 2 near the lower end is integrally provided with a water inlet pipe 21, and the inner side of the transmission pipe 1 is provided with a water outlet pipe 22. A condensation rack 3 for condensing water vapor is connected between the water outlet pipe 22 and the condenser pipe 2;

[0032] The condensation rack 3 includes a plurality of circumferentially distributed rotatable inner inclined heat exchange tubes 39. The water in the plurality of inner inclined heat exchange tubes 39 moves from bottom to top, and is used to condense the water vapor contacting the outer wall of the inner inclined heat exchange tubes 39. The inclined inner inclined heat exchange tubes 39 allow the water vapor to flow along the inner inclined heat exchange tubes 39 after liquefaction, so that the subsequent water vapor is ensured to contact the inner inclined heat exchange tubes 39.

[0033] The outer side of the water inlet pipe 21 is connected to a water pump for conveying water, and the outer side of the water outlet pipe 22 is connected to a water source, so that the cooling medium, that is, water, is conveyed, and the movement of water can enhance the convective heat exchange effect in the inner inclined heat exchange tube 39. The heat conduction efficiency between static water layers is low, while flowing water can continuously bring heat from the high temperature area to the low temperature area, and exchange heat with the outside through the wall of the inner inclined heat exchange tube 39. This convection effect significantly improves the rate and efficiency of heat exchange, making the liquefaction process faster and more effective.

[0034] The lower end of the transmission pipe 1 is also configured to protrude downwards, so as to collect and discharge the condensed water, and to collect the waste water generated after liquefaction, so as to facilitate subsequent treatment.

[0035] The condensation rack 3 also includes a metal ring 31 for fixing and a matching ring 36 rotatably arranged in the metal ring 31. The upper and lower sides of the metal ring 31 are provided with an inlay groove 32. The inlay groove 32 is provided with a sealing ring 33 to prevent gas leakage. The transmission tube 1 is divided into two sections, the upper and lower sections, by the metal ring 31. The two sections of the transmission tube 1 extend into the inlay grooves 32 on the upper and lower sides respectively, and the two sections are fixed by extrusion. During the water vapor transmission process, the condensation rack 3 is contacted and the operation is performed directly inside the transmission tube 1, so that the structure is simple and there is no need to perform other operations on the water vapor again. In addition, a large amount of latent heat will be released when the water vapor is condensed, and this part of the heat can be effectively utilized. After the water vapor is condensed into liquid water, its volume will be greatly reduced, which is conducive to subsequent storage, transportation and processing.

[0036] In order to install the condensation rack 3, as Figure 4 and Figure 5 As shown, the metal ring 31 is fixedly sleeved on the inner side of the condenser 2 , the interior of the metal ring 31 is hollow, and a water inlet 34 connected to the condenser 2 is provided on the outer side of the metal ring 31 for conveying water into the metal ring 31 .

[0037] In order to realize the function that the inner inclined heat exchange tube 39 can rotate and at the same time minimize the leakage of water used for heat exchange, the inner side of the metal ring 31 is also provided with a circle of annular cavity 35 arranged coaxially with the metal ring 31, the outer side of the matching ring 36 extends into the annular cavity 35, and the upper and lower sides of the matching ring 36 are respectively in contact with the upper and lower sides of the annular cavity 35, and the inner side of the metal ring 31 is also provided with two circles of sealing ring layers 37, which are both fixed on the inner side of the metal ring 31. The sealing ring layer 37 is used to limit the matching ring 36, and the inner and outer sides of the matching ring 36 are both fitted with rubber rings 38. The outer rubber ring 38 is pressed against the inner wall of the metal ring 31, and the inner rubber ring 38 is pressed against the sealing ring layer 37, so that the inner inclined heat exchange tube 39 can rotate with the matching ring 36, and even if a gap is generated on the outer side of the matching ring 36 under the action of high temperature and movement, it is also used to move the water used for heat exchange into the transmission pipe 1, so as to maintain the integrity of the equipment and prevent the heat exchange water from contacting the liquefied wastewater and the liquefied wastewater from moving outward.

[0038] During the heat exchange process, the heat exchange medium needs to flow inside the inner inclined heat exchange tube 39, and the two ends of the inner inclined heat exchange tube 39 need to be connected. Multiple inner inclined heat exchange tubes 39 are inserted into the matching ring 36 at an angle downward, and the inclined lower end of the inner inclined heat exchange tube 39 is connected to the inside of the metal ring 31, and the inclined upper end of the inner inclined heat exchange tube 39 is fixed to the water outlet pipe 22 and its interior is connected to the inside of the water outlet pipe 22.

[0039] like Figure 6 As shown, in the top view of the inner inclined heat exchange tube 39, during the rotation process, most of the exhaust gas moving upward can contact the inner inclined heat exchange tube 39, thereby liquefying the water vapor to a great extent.

[0040] like Figure 2 As shown, the servo motor 4 is installed, and the interior of the transmission tube 1 is also provided with a servo motor 4 for driving the matching ring 36 to rotate. The servo motor 4 is located at the upper end of the condensation rack 3. The outside of the servo motor 4 has a protective shell, and the protective shell is fixed to the inner wall of the transmission tube 1. A gear 1 41 is fixed to the output end of the servo motor 4, and a gear 2 42 is fixedly sleeved on the outside of the water outlet pipe 22. The gear 1 41 is meshed with the gear 2 42. The servo motor 4 is located at the upper end of the condensation rack 3 to avoid water vapor from contacting the servo motor 4 as much as possible to avoid damage to the servo motor 4.

[0041] An adsorption layer 5 is also provided in the transmission pipe 1. The adsorption layer 5 is located at the upper end of the condensation rack 3 and is used for adsorbing harmful substances in the exhaust gas.

[0042] The adsorption layer 5 is porous activated carbon. The activated carbon has an extremely high specific surface area, which means that there are a large number of adsorption sites on its surface, which can efficiently adsorb pollutants in the exhaust gas. There are abundant micropores and mesopore structures inside the activated carbon. These pores provide a large amount of space and channels for the adsorption process, allowing the pollutant molecules in the exhaust gas to enter smoothly and be adsorbed. Activated carbon is widely used in industrial waste gas treatment and laboratory waste gas treatment due to its excellent adsorption performance, and has become an important material in the field of waste gas purification.

[0043] like Figure 3 As shown, an inner partition 23 is longitudinally fixed on the inner wall of the lower end of the condenser 2, and the axis of the inner partition 23 coincides with the axis of the condenser 2. The inner partition 23 is used to change the route of water movement, so that the water enters the outside of the inner partition 23, then moves upward, passes through the upper end of the inner partition 23, and then moves downward and enters the metal ring 31, so that the water in the condenser 2 moves, the movement path of the water is increased, and the water in the condenser 2 is replaced.

[0044] The working principle of the present invention is that when the decorative cloth is printed, especially the decorative cloth with fluff, the fluff on the surface of the decorative cloth will absorb a certain amount of ink, dye and other chemical additives during the printing process. These substances are easy to volatilize during the drying process, thereby increasing the pollutant content in the exhaust gas.

[0045] To this end, the waste gas generated during the drying process will be discharged through the transmission pipe 1. The transmission pipe 1 is an ordinary pipe. A condenser 2 is provided on the transmission pipe 1, and the local transmission pipe 1 is covered so that the water vapor in the drying process condenses to form water, avoiding transmission with the waste gas, thereby reducing the complexity of waste gas treatment.

[0046] In addition, the inner inclined heat exchange tube 39 can rotate under the action of the servo motor 4. The rotating inner inclined heat exchange tube 39 has a large contact area with the moving water vapor, and also produces a stirring effect, which liquefies most of the passing water vapor into water, thereby improving the efficiency of liquefaction. The water vapor may contain impurities or salts, which may be deposited and form scale when the surface of the inner inclined heat exchange tube 39 is cooled. Rotating the inner inclined heat exchange tube 39 helps to reduce this scaling phenomenon, because the deposits are not easy to adhere to the tube wall during the rotation process. Rotation may also help the water vapor to be evenly distributed outside the inner inclined heat exchange tube 39, thereby ensuring that the entire heat exchange tube can effectively perform heat exchange and liquefaction processes.

[0047] In addition, the inclined inner inclined heat exchange tube 39 is inclined downward to help the liquefied water flow downward along the outer wall of the inner inclined heat exchange tube 39, reducing the possibility of water accumulation on the tube wall, thereby improving the heat exchange efficiency and preventing the formation of scale. In addition, there is a centrifugal force generated by the rotation, which makes it easier for the liquefied water to move along the inner inclined heat exchange tube 39, so that the water vapor can always be in contact with the outer wall of the inner inclined heat exchange tube 39, ensuring that it is not blocked by the liquefied water.

[0048] It should be noted that when the high-temperature water vapor contacts the outer wall of the inner inclined heat exchange tube 39 with a lower temperature, it releases heat and lowers the temperature. As the temperature decreases, the water vapor gradually reaches below its dew point and begins to liquefy into water. Liquefaction is an exothermic process, but in this system, since the inner inclined heat exchange tube 39 continuously absorbs heat from the water vapor and transfers it to the surrounding environment, the liquefaction process can continue.

[0049] The matching ring 36 can rotate, and there are rubber rings 38 on both the inner and outer sides of the matching ring 36 to prevent the water in the metal ring 31 from leaking out. Even if leakage occurs, it will move outward from the gap outside the matching ring 36 to the inside of the transmission pipe 1 to mix with the liquefied water, thereby avoiding leakage to the outside and maintaining the integrity of the equipment.

[0050] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
