[0043] In the description of the utility model, it is necessary to explain, unless another explicit provision and limitation, such as the term '' installation '' '' connected '' '' connected '' should be broad sense understanding, for example, can be fixedly connected, can also be detachable connection, or integrally connected;Can be mechanical connection, can also be electrical connection;Can be direct connection, can also be indirectly connected through the intermediate medium, can be the intercommunication of two elements inside.For the person skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0044] Example one

[0045] Refer to Figures 1-6 A quick-release gas drying pipe for the inlet of chemical tower, comprising: a drying pipe body 1, which has a filter cavity 11 inside, the two ends of the drying pipe body 1 form a first port 12 and a second port 13, a first union joint 14 is threadedly connected at the first port 12, and a second union joint 15 is threadedly connected at the second port 13; a drying filter medium 2 filled in the filter cavity 11; a first sleeve joint 16, one end of which is threadedly connected with the first union joint 14, and the other end is connected with an external gas pipe 81; and a second sleeve joint 17, one end of which is threadedly connected with the second union joint 15, and the other end is connected with a chemical tower inlet pipe 82.

[0046] It is worth mentioning that, the obvious difference with the prior art is that, the application scheme further comprises: a quick pipe clamping assembly 3, which is composed of a fixed semicircular pipe clamping body 31 and a movable semicircular pipe clamping body 32, a first fastener and a second fastener; the fixed semicircular pipe clamping body 31 extends outwardly on both sides to form a first flat connecting part 311, a circular connecting hole 312 is formed in the first flat connecting part 311, a connecting column 313 is outwardly protruded in the middle of the fixed semicircular pipe clamping body 31, and a fixing hole 314 is formed in the connecting column 313; the movable semicircular pipe clamping body 32 extends outwardly on both sides to form a second flat connecting part 321, a waist-shaped connecting hole 322 is formed in the second flat connecting part 321, the length of the waist-shaped connecting hole 322 is greater than the diameter of the circular connecting hole 312, so that the waist-shaped connecting hole 322 forms an adjusting section 3221 relative to the circular connecting hole 312; the first fastener (such as a screw, not shown in the drawing) is inserted into the waist-shaped connecting hole 322 and the circular connecting hole 312, so as to fixedly connect the fixed semicircular pipe clamping body 31 and the movable semicircular pipe clamping body 32, and clamp the drying pipe body 1 between the fixed semicircular pipe clamping body 31 and the movable semicircular pipe clamping body 32; the second fastener (such as a screw, not shown in the drawing) is connected to the external support 83 at one end and inserted into the fixing hole 314 of the connecting column 313 at the other end, so as to fix the quick pipe clamping assembly 3 on the external support 83.

[0047] The above is the basic structure scheme of the utility model, and the advantages are at least: 1. Through the quick connecting pipe clamping assembly 3, the drying pipe body 1 can be clamped and quickly connected to the external support 83 (chemical tower 8), realizing connection and fixation; 2. When disassembling, only the first fastener is removed, and the movable semicircular pipe clamping body and the fixed semicircular pipe clamping body 31 can be separated, so that the drying pipe body 1 can be quickly disassembled, and the drying pipe body 1 can be conveniently maintained; 3. In terms of gas path, the first clamping sleeve joint 16 is connected with the external gas pipe 81, and the second clamping sleeve joint 17 is connected with the chemical tower gas inlet pipe 82, so that the gas path can be connected and conducted. 4. When there are errors in the precision of the production and position of each component, or when different specifications and sizes of external supports 83 are used, the combination of the waist-shaped connecting hole 322 and the circular connecting hole 312 can adaptively adjust the relative position relationship between the movable semicircular pipe clamping body 32 and the fixed semicircular pipe clamping body 31, so as to eliminate the precision error and make the connection more stable and reliable.

[0048] In some preferred embodiments of the utility model, the first clamping sleeve joint 16 and the first movable joint 14 are provided with a gas flow sensor 4 between the threads. Because the filter cavity 11 has a certain drying and filtering effect on the gas, impurities in the gas will be trapped. When the impurities accumulate enough, they will block the passage, causing the gas flow to slow down, and the drying and filtering effect will be greatly reduced. Therefore, by providing a flow sensor, the flow sensor is in communication connection with the control center of the equipment. Once the gas flow index is abnormal, the control center can receive feedback in the first time, so that the staff can quickly troubleshoot. And the gas flow sensor 4 is arranged at both ends, which can detect the inlet gas flow and outlet gas flow respectively, observe the flow difference of the inlet and outlet gas in time, and timely eliminate the safety hazards caused by excessive internal pressure (bursting) or insufficient internal pressure.

[0049] Embodiment two

[0050] The quick-release gas drying pipe described above is applied to the gas inlet of the chemical tower 8. During operation, the chemical tower 8 will generate a large amount of heat, so at least part of the heat will be conducted to the quick-release gas drying pipe, causing the surface temperature of the quick-release gas drying pipe to rise. At this time, if the staff directly performs disassembly work, there will be a high risk of scalding.

[0051] Under normal circumstances, the staff will tentatively touch the drying pipe body 1. Although this method will not cause extremely serious consequences, it inevitably has safety risks, and there are many cases of local hand scalding in the field every year.

[0052] To eliminate the above-mentioned defects, the structural scheme provided by the embodiment is as follows: referring to Figure 10 , a temperature-sensitive coating is arranged on at least part of the outer wall of the drying pipe body 1 to form a temperature-sensitive layer 5. A specific example is that the critical temperature value of the temperature-sensitive layer 5 is 40°; when the real-time temperature at the temperature-sensitive layer 5 is lower than or equal to 40°, the temperature-sensitive layer 5 presents a first color 51; when the real-time temperature at the temperature-sensitive layer 5 is higher than 40°, the temperature-sensitive layer 5 presents a second color 52. When handling, the worker can directly observe the color (the first color 51 or the second color 52) presented by the temperature-sensitive layer 5 with the naked eye; if it is the first color 51, it belongs to the safe temperature range, and the worker can directly operate; if it is the second color 52, the worker can wait for cooling or pour low-temperature liquid on the drying pipe body 1 to rapidly cool it, and then operate after changing to the first color 51.

[0053] Embodiment three

[0054] In some preferred embodiments of the utility model, the filter cavity 11 is separated into multiple single chambers 111 by multiple separation supports 6. In order to realize gas flow, adjacent single chambers 111 need to be mutually conductive. It is worth mentioning that each single chamber 111 can be independently filled with the same or different types of drying filter medium 2. That is, the user has the autonomy to select the drying filter medium 2 in each single chamber 111, which can achieve different drying and filtering effects on the gas when different drying filter media 2 are filled; when the same drying filter medium 2 is filled, the single drying and filtering effect is greatly improved.

[0055] Optionally, the drying filter medium 2 includes any one or more of activated carbon particles, silica gel particles, metal organic framework compound particles, and adsorption resin particles.

[0056] The activated carbon particles can adsorb moisture in the air and reduce humidity. This feature enables them to dry the air in some environments, making them suitable for moisture-proof and drying treatment of stored goods. By absorbing moisture and releasing water, activated carbon can help regulate the humidity of the environment, keeping it within a relatively stable range. The porous structure of activated carbon particles provides a large specific surface area, enabling them to effectively adsorb pollutants and odors in the gas, including volatile organic compounds (VOCs), smoke, ammonia, and other harmful substances. In air purification, activated carbon particles can capture fine particulate matter in the air, improving air quality. Furthermore, activated carbon particles can be functionalized to enhance their adsorption capacity for specific gases, such as odor molecules or toxic gases.

[0057] Silica gel particles are a common desiccant with a strong hygroscopic capacity, effectively absorbing moisture from the air. Once saturated with moisture, they can be regenerated by heating or other methods to restore their hygroscopic capacity, making them reusable. The microporous structure of silica gel particles also allows for a limited filtering of small airborne particles, including dust and impurities. Furthermore, silica gel particles have relatively low adsorption of chemicals and do not react with most gases, thus maintaining excellent filtration performance in certain applications.

[0058] Among them, Metal-Organic Frameworks (MOFs) particles have a very high specific surface area, usually around 1000m 2 / g or more, which gives them excellent hygroscopicity and the ability to effectively absorb moisture from the air. They can be designed to have a high affinity for water while having a low affinity for other gases, enabling more efficient drying under specific conditions. They can usually be regenerated by heating or reducing pressure to restore their hygroscopic capacity, demonstrating excellent recyclability. Furthermore, metal-organic framework particles can effectively remove volatile organic compounds (VOCs), odors, and pollutants from the air, improving air quality.

[0059] Certain types of adsorption resin particles (such as polystyrene resins) can effectively absorb moisture from the air and possess a high hygroscopic capacity. These particles typically react quickly to moisture, rapidly reducing the humidity in the air. These particles can be regenerated through heating, vacuuming, or blowing air to restore their hygroscopic properties, making them economical for repeated use. Furthermore, the porous structure of these particles allows them to capture solid particles and liquid droplets suspended in the air, making them suitable for use as particulate filtration media. These particles possess the ability to selectively adsorb specific molecules or gases, effectively removing specific pollutants or harmful gases from the air.

[0060] Example 4

[0061] Based on the structure of the third embodiment, this embodiment provides a more preferred solution, which is as follows: Figures 7-8 The partition bracket 6 is in the shape of a Chinese character "U." The cross-section of the filter cavity 11 is circular, and the diagonal length of the partition bracket 6 is equal to the inner diameter of the filter cavity 11. The specific shape of the partition bracket 6 provides good support and divides the space of the filter cavity 11. Furthermore, the center of the "U"-shaped partition bracket 6 has a through hole 61, and a gap 62 exists between the "U"-shaped partition bracket 6 and the inner wall of the filter cavity 11. This allows gas to pass smoothly from the center and edges, improving gas flow efficiency.

[0062] If the gas flows directly forward in the filter cavity 11 in one direction, especially when the pressure is large, the time and area of the gas contacting the dry filter medium 2 are not enough, which results in poor drying and filtering effect and affects the subsequent use. Figure 9 The single cavity 111 is also provided with a plurality of blocking ribs 7, and the adjacent blocking ribs 7 are staggered to form a winding filter flow channel 71 in the single cavity 111. Through the arrangement of the blocking ribs 7, the gas is forced to flow along the winding filter flow channel 71, so that the gas has enough time and area to contact the dry filter medium 2, and the good drying and filtering effect of the gas is ensured.

[0063] It should be pointed out that other technical solutions of the present application are all prior art, and therefore will not be described in detail.

[0064] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the art, a number of improvements and refinements can be made without departing from the concept of the present application, and these improvements and refinements should also be considered within the scope of protection of the present application.
