Description

Technical Field

[0001] The invention relates to the technical field of energy-saving, environmentally friendly and cleaning technology, and in particular to a single-tube regeneration filter element device. Background Art

[0002] Mass spectrometry (MS) is a highly sensitive analytical method that ionizes chemical substances and uses electric and magnetic fields in the gas phase to separate ions according to their mass-to-charge ratio for detection. The filter element is one of the essential components of mass spectrometry detection instruments. The quality of the filter element affects the sample separation environment and detection results.

[0003] The traditional double-tube regeneration filter element has the function of filtering and drying the system gas. The double-tube regeneration filter element uses and regenerates two regeneration filter elements in rotation, and the regeneration cycle is manually set based on experience to provide a dry and clean gas environment for the system.

[0004] The main disadvantage of the double-tube regeneration filter element is that no matter which filter barrel is being regenerated, air must always be added to the system from the outside, which is not conducive to the stability of the system. The filter material of the double-tube regeneration filter element also has a lifespan problem, and it does not have the convenience of flexibly replacing dry and clean filter material. Summary of the invention

[0005] In view of this, the present invention provides a single-tube regeneration filter element device to solve the problem that in the traditional double-tube regeneration filter element, no matter which filter element barrel is being regenerated, air always needs to be added into the system from the outside, and dry and clean filter materials cannot be flexibly replaced.

[0006] In a first aspect, the present invention provides a single-tube regeneration filter element device, comprising:

[0007] A first pipeline, wherein an air inlet of the first pipeline is adapted to be in communication with an external air source, and an air outlet of the first pipeline is in communication with a non-regeneration filter cartridge barrel;

[0008] A three-way solenoid valve A, wherein the normally closed end of the three-way solenoid valve A is connected to the first pipeline, the normally open end of the three-way solenoid valve A is connected to the first air outlet of the regeneration filter cartridge barrel, and the common end of the three-way solenoid valve A is connected to the non-regeneration filter cartridge barrel;

[0009] A three-way connector A, wherein two interfaces of the three-way connector A are connected to the first pipeline, and the other interface of the three-way connector A is connected to the air inlet of the regeneration filter cartridge barrel through the second pipeline;

[0010] A three-way solenoid valve B, wherein the normally open end of the three-way solenoid valve B is connected to the second pipeline, the normally closed end of the three-way solenoid valve B is connected to the three-way connector B on the first pipeline, and the common end of the three-way solenoid valve B is connected to the regeneration filter cartridge barrel;

[0011] Under normal working conditions, the regeneration filter cartridge barrel is connected in series with the non-regeneration filter cartridge barrel, and the gas to be filtered passes through the regeneration filter cartridge barrel and the non-regeneration filter cartridge barrel in sequence before being discharged;

[0012] In the regeneration working state, most of the gas to be filtered passes through the non-regeneration filter cartridge barrel alone and is discharged, and the remaining part of the gas to be filtered passes through the heated regeneration filter cartridge barrel alone and is discharged from the second air outlet of the regeneration filter cartridge barrel.

[0013] The above structure, by setting the first pipeline, three-way solenoid valve A, three-way connector A and three-way solenoid valve B, allows the non-regeneration filter cartridge barrel and the regeneration filter cartridge barrel to be connected in multiple ways. Under normal working conditions, the regeneration filter cartridge barrel is connected in series with the non-regeneration filter cartridge barrel, and the gas to be filtered is discharged after passing through the regeneration filter cartridge barrel and the non-regeneration filter cartridge barrel in sequence. In this state, the gas to be filtered first passes through the regeneration filter cartridge barrel, and then enters the non-regeneration filter cartridge barrel after being filtered by the regeneration filter cartridge barrel. It can be understood that since the regeneration filter cartridge barrel has completed the filtration of most of the impurities in the gas to be filtered, after the gas reaches the non-regeneration filter cartridge barrel, the working intensity of the non-regeneration filter cartridge barrel is reduced. By connecting the regeneration filter cartridge barrel and the non-regeneration filter cartridge barrel in series, the service life of the non-regeneration filter cartridge barrel can be increased. And since the regeneration filter cartridge barrel is regenerable, the non-regeneration filter cartridge barrel is placed before the regeneration filter cartridge barrel to filter the gas to be filtered. In the regeneration working state, by changing the closing conditions of the interfaces of the three-way solenoid valve A and the three-way solenoid valve B, most of the gas to be filtered is discharged after passing through the non-regeneration filter cartridge barrel alone. At this time, the non-regeneration filter cartridge barrel plays a filtering role on the gas to be filtered, and the regeneration filter cartridge barrel needs to remove impurities inside it. The basic principle of filter cartridge regeneration is to heat the filter cartridge being regenerated and purge with a certain flow of gas to discharge moisture out of the system. In the present invention, the remaining part of the gas to be filtered is set to pass through the heated regeneration filter cartridge barrel alone and then be discharged from the second gas outlet of the regeneration filter cartridge barrel to achieve the above-mentioned gas purge and discharge moisture out of the system. In the traditional filter cartridge regeneration process, in order to ensure the gas balance of the system, it is necessary to supplement gas from the outside to enter the system, which is not conducive to the stability of the system. In this embodiment, a part of the gas in the air inlet of the first pipeline is diverted for use in the regeneration process of the regeneration filter cartridge barrel, which can avoid supplementing gas from the outside to enter the system.

[0018] In an optional embodiment, the fixing shell fixes the non-regeneration filter cartridge barrel by its own elastic force;

[0019] Or a limiting structure is provided on the fixed shell, and the fixed shell fixes the non-regeneration filter cartridge barrel via the limiting structure.

[0020] In an optional embodiment, the regeneration filter cartridge barrel comprises a shell, a heat-insulating cotton disposed outside the shell, and a heating element disposed inside the shell;

[0021] In the regeneration working state, the heating element is energized to heat the outer shell and the filter element inside the outer shell, and the hot and humid air inside the regeneration filter element barrel is carried out through the gas to be filtered inside the regeneration filter element barrel.

[0022] In an optional embodiment, filter screens are provided at the air inlet and air outlet ends of the non-regeneration filter cartridge barrel and the regeneration filter cartridge barrel.

[0023] In an optional embodiment, the single-tube regeneration filter element device further includes a three-way solenoid valve C, and the three-way solenoid valve C is connected to the second air outlet of the regeneration filter element barrel.

[0024] In an optional embodiment, the single-tube regeneration filter element device also includes a solenoid valve fixing frame, which is fixed to the base frame, and the three-way solenoid valve A, the three-way solenoid valve B and the three-way solenoid valve C are fixed in parallel on the solenoid valve fixing frame.

[0025] In an optional embodiment, the single-tube regeneration filter element device also includes a sponge box, which is fixed to the solenoid valve fixing frame, the interior of the sponge box is suitable for placing a sponge, and the end of the pipe connected to the second air outlet of the regeneration filter element barrel is placed in the sponge box.

[0026] The single-tube regeneration filter device of this structure is in the regeneration working state. In the present invention, the remaining part of the gas to be filtered is arranged to pass through the heated regeneration filter barrel alone and then be discharged from the second air outlet of the regeneration filter barrel, so as to realize the above-mentioned gas purge and discharge the moisture from the system. In the present invention, a sponge box is fixed on the base frame, a sponge is placed inside the sponge box, and the end of the pipe connected to the second air outlet of the regeneration filter barrel is placed in the sponge box. Therefore, after the moisture is discharged from the second air outlet of the regeneration filter barrel, the sponge inside the sponge box can absorb the moisture in the gas.

[0027] In an optional embodiment, the single-tube regeneration filter element device also includes a temperature and humidity sensor and a pressure sensor, which are configured to detect environmental parameters so as to be suitable for calculating the regeneration cycle parameters of the regeneration filter element barrel based on the measured environmental parameters.

[0028] The single-tube regeneration filter element device of this structure measures the temperature, humidity, pressure and other parameters of the use environment by setting temperature and humidity sensors and pressure sensors. According to the environmental parameters, the algorithm is trained to calculate the regeneration cycle parameters that are most suitable for the filter element regeneration in the environment, so as to achieve the maximum efficiency of use. The specific algorithm can be analyzed using existing technology.

Under normal working conditions, the regenerative filter cartridge barrel is connected in series with the non-regenerative filter cartridge barrel, and the gas to be filtered is discharged after passing through the regenerative filter cartridge barrel and the non-regenerative filter cartridge barrel in sequence. In this state, the gas to be filtered first passes through the regenerative filter cartridge barrel, and then enters the non-regenerative filter cartridge barrel after being filtered by the regenerative filter cartridge barrel. It can be understood that since the regenerative filter cartridge barrel has completed the filtration of most of the impurities in the gas to be filtered, the working intensity of the non-regenerative filter cartridge barrel is reduced after the gas reaches the non-regenerative filter cartridge barrel. By connecting the regenerative filter cartridge barrel and the non-regenerative filter cartridge barrel in series, the service life of the non-regenerative filter cartridge barrel can be increased. And since the regenerative filter cartridge barrel is regenerative, the non-regenerative filter cartridge barrel is placed before the regenerative filter cartridge barrel to filter the gas to be filtered. In the regeneration working state, by changing the closing conditions of the interfaces of the three-way solenoid valve A and the three-way solenoid valve B, most of the gas to be filtered is discharged after passing through the non-regeneration filter cartridge barrel alone. At this time, the non-regeneration filter cartridge barrel plays a filtering role on the gas to be filtered, and the regeneration filter cartridge barrel needs to remove impurities inside it.

[0063] Example 1

[0064] Mass spectrometry (MS) is a highly sensitive analytical method that ionizes chemical substances and uses electric and magnetic fields in the gas phase to separate ions according to their mass-to-charge ratio for detection. The filter element is one of the essential components of mass spectrometry detection instruments. The quality of the filter element affects the sample separation environment and detection results.

[0065] The traditional double-tube regeneration filter element has the function of filtering and drying the system gas. The double-tube regeneration filter element uses and regenerates two regeneration filter elements in rotation, and the regeneration cycle is manually set based on experience to provide a dry and clean gas environment for the system.

[0066] The main disadvantage of the double-tube regeneration filter element is that no matter which filter barrel is being regenerated, air must always be added to the system from the outside, which is not conducive to the stability of the system. The filter material of the double-tube regeneration filter element also has a lifespan problem, and it does not have the convenience of flexibly replacing dry and clean filter material.

[0067] To this end, a single-tube regeneration filter element device is provided in this embodiment to solve the above-mentioned problem.

[0068] In this embodiment, if Figures 1 to 5As shown, the single-tube regeneration filter element device includes a first pipeline 1, a three-way solenoid valve A4, a three-way connector A5 and a three-way solenoid valve B7. The air inlet of the first pipeline 1 is suitable for communicating with an external air source, and the air outlet of the first pipeline 1 is connected to the non-regeneration filter element barrel 2; the normally closed end of the three-way solenoid valve A4 is connected to the first pipeline 1, the normally open end of the three-way solenoid valve A4 is connected to the first air outlet of the regeneration filter element barrel 3, and the common end of the three-way solenoid valve A4 is connected to the non-regeneration filter element barrel 2; the two interfaces of the three-way connector A5 are connected to the first pipeline 1, and the other interface of the three-way connector A5 is connected to the air inlet of the regeneration filter element barrel 3 through the second pipeline 6; the normally open end of the three-way solenoid valve B7 is connected to the second pipeline 6, the normally closed end of the three-way solenoid valve B7 is connected to the three-way connector B8 on the first pipeline 1, and the common end of the three-way solenoid valve B7 is connected to the regeneration filter element barrel 3. In the present embodiment, the single-tube regenerative filter element device has a normal working state and a regeneration working state. In the normal working state, the regeneration filter element barrel 3 is connected in series with the non-regeneration filter element barrel 2, and the gas to be filtered passes through the regeneration filter element barrel 3 and the non-regeneration filter element barrel 2 in turn and is discharged; in the regeneration working state, most of the gas to be filtered passes through the non-regeneration filter element barrel 2 alone and is discharged, and the remaining part of the gas to be filtered passes through the heated regeneration filter element barrel 3 alone and is discharged from the second gas outlet of the regeneration filter element barrel 3.

[0069] The above structure, by setting the first pipeline 1, the three-way solenoid valve A4, the three-way connector A5 and the three-way solenoid valve B7, enables the non-regeneration filter cartridge barrel 2 and the regeneration filter cartridge barrel 3 to have multiple ways of connection. Under normal working conditions, the regeneration filter cartridge barrel 3 is connected in series with the non-regeneration filter cartridge barrel 2, and the gas to be filtered is discharged after passing through the regeneration filter cartridge barrel 3 and the non-regeneration filter cartridge barrel 2 in sequence. In this state, the gas to be filtered first passes through the regeneration filter cartridge barrel 3, and then enters the non-regeneration filter cartridge barrel 2 after being filtered by the regeneration filter cartridge barrel 3. It can be understood that since the regeneration filter cartridge barrel 3 has completed the filtration of most of the impurities in the gas to be filtered, the working intensity of the non-regeneration filter cartridge barrel 2 is reduced after the gas reaches the non-regeneration filter cartridge barrel 2. By connecting the regeneration filter cartridge barrel 3 and the non-regeneration filter cartridge barrel 2 in series, the service life of the non-regeneration filter cartridge barrel 2 can be increased. And since the regeneration filter cartridge barrel 3 is regenerable, the non-regeneration filter cartridge barrel 2 is placed before the regeneration filter cartridge barrel 3 to filter the gas to be filtered.

[0070] In the regeneration working state, by changing the closing state of the interface of the three-way solenoid valve A4 and the three-way solenoid valve B7, most of the gas to be filtered passes through the non-regeneration filter cartridge barrel 2 alone and is discharged. At this time, the non-regeneration filter cartridge barrel 2 plays a filtering role on the gas to be filtered, and the regeneration filter cartridge barrel 3 needs to remove impurities inside it. The basic principle of filter cartridge regeneration is to heat the filter cartridge being regenerated and purge with a certain flow of gas to discharge moisture out of the system. In this embodiment, the remaining part of the gas to be filtered passes through the heating regeneration filter cartridge barrel 3 alone and is discharged from the second gas outlet of the regeneration filter cartridge barrel 3 to achieve the above-mentioned gas purge and discharge moisture out of the system. In the traditional filter cartridge regeneration process, in order to ensure the gas balance of the system, it is necessary to supplement gas from the outside to enter the system, which is not conducive to the stability of the system. In this embodiment, a part of the gas in the air inlet of the first pipeline 1 is diverted for use in the regeneration process of the regeneration filter cartridge barrel 3, which can avoid supplementing gas from the outside to enter the system.

[0071] Specifically, Figure 6 As shown, under normal working conditions, the gas to be filtered enters the first pipeline 1 from the air inlet of the first pipeline 1. At this time, the lower end interface of the three-way solenoid valve B7 is closed, the upper end interface of the three-way solenoid valve A4 is closed, and the upper end interface of the three-way solenoid valve C13 is closed, so that the gas to be filtered enters the first pipeline 1 from the air inlet of the first pipeline 1, and then passes through the three-way connector A5 and the three-way solenoid valve B7 in sequence to reach the regeneration filter cartridge barrel 3, and after being filtered by the regeneration filter cartridge barrel 3, it reaches the three-way solenoid valve A4 from the air outlet of the regeneration filter cartridge barrel 3, and then passes through the three-way solenoid valve A4 to reach the non-regeneration filter cartridge barrel 2, and is discharged from the air outlet of the non-regeneration filter cartridge barrel 2 after being filtered by the non-regeneration filter cartridge barrel 2.

[0072] like Figure 6 As shown, when the regeneration filter cartridge barrel 3 needs to be regenerated, the upper interface of the three-way solenoid valve B7 is closed and the lower interface is opened, the upper interface of the three-way solenoid valve A4 is opened and the lower interface is closed, and the upper interface of the three-way solenoid valve C13 is opened and the lower interface is closed. Then the single-tube regeneration filter cartridge device enters the regeneration working state. In the regeneration working state, the gas to be filtered enters the first pipeline 1 from the air inlet of the first pipeline 1. After the gas to be filtered passes through the three-way joint B8, due to the setting of the two-way speed regulating valve 9, most of the gas to be filtered passes through the three-way joint B8 and enters the first pipeline 1, and then reaches the three-way solenoid valve A4 and enters the non-regeneration filter cartridge barrel 2. After being filtered by the non-regeneration filter cartridge barrel 2, it is discharged from the air outlet of the non-regeneration filter cartridge barrel 2. A small part of the gas to be filtered passes through the three-way joint B8, passes through the two-way speed regulating valve 9 and the three-way solenoid valve B7 to reach the regeneration filter cartridge barrel 3. The interior of the regeneration filter cartridge barrel 3 is heated to generate moisture. The small part of the gas to be filtered that reaches the regeneration filter cartridge barrel 3 takes away the moisture generated inside the regeneration filter cartridge barrel 3, flows through the air outlet of the regeneration filter cartridge barrel 3 to the three-way solenoid valve C13, and flows out through the three-way solenoid valve C13.

[0073] In this embodiment, if Figure 4 As shown, the single-tube regeneration filter element device is provided with a two-way speed regulating valve 9, and the two-way speed regulating valve 9 is connected between the three-way connector B8 and the three-way solenoid valve B7.

[0074] As mentioned above, during the regeneration process of the regenerated filter cartridge barrel 3, a portion of the gas in the air inlet of the first pipeline 1 needs to be diverted for use in the regeneration process of the regenerated filter cartridge barrel 3. In order to enable most of the gas to be filtered to enter the non-regenerated filter cartridge barrel 2 for filtration, a small portion of the gas is allowed to enter the regenerated filter cartridge barrel 3. Therefore, a two-way speed regulating valve 9 is arranged between the three-way connector B8 and the three-way solenoid valve B7. The two-way speed regulating valve 9 is adjusted to adjust the amount of gas entering the regenerated filter cartridge barrel 3.

[0075] In this embodiment, if Figure 1 As shown, the single-tube regenerative filter element device also includes a base frame 10, and a non-regenerative filter element barrel 2 and a regenerative filter element barrel 3 are arranged in the base frame 10; a fixed shell 11 is fixed on the base frame 10, and the non-regenerative filter element barrel 2 is inserted into the fixed shell 11.

[0076] In the above structure, the base frame 10 includes an upper fixed plate, a side plate and a lower fixed plate. The upper fixed plate and the lower fixed plate are respectively fixed to the two ends of the side plates, and the bottom of the lower fixed plate is provided with a support foot. When installing the regenerated filter cartridge barrel 3 and the non-regenerated filter cartridge barrel 2, the regenerated filter cartridge barrel 3 and the non-regenerated filter cartridge barrel 2 are both installed between the upper fixed plate and the lower fixed plate. At the installation position of the regenerated filter cartridge barrel 3, the upper fixed plate and the lower fixed plate are both provided with grooves, and the two ends of the regenerated filter cartridge barrel 3 are placed inside the grooves on the upper fixed plate and the lower fixed plate to limit the position of the regenerated filter cartridge barrel 3. At the same time, the upper fixed plate and the lower fixed plate are both provided with through holes in the groove position, and an interface is provided inside the through hole for connecting the air outlet and the air inlet of the regenerated filter cartridge barrel 3. Similarly, at the installation position of the non-regenerative filter cartridge barrel 2, a fixed shell 11 is fixed between the upper fixed plate and the lower fixed plate, the fixed shell 11 is open downward, and a through hole is provided on the lower fixed plate. This through hole is used to pull the non-regenerative filter cartridge barrel 2 out of the fixed shell 11 through the through hole, so as to facilitate the replacement of the filter cartridge inside the non-regenerative filter cartridge barrel 2.

[0077] In this embodiment, the fixed shell 11 fixes the non-regeneration filter cartridge barrel 2 by its own squeezing force. That is, the fixed shell 11 is made of elastic material, and after the non-regeneration filter cartridge barrel 2 is inserted into the fixed shell 11, the non-regeneration filter cartridge barrel 2 abuts against the side wall of the fixed shell 11 and causes the fixed shell 11 to deform elastically, thereby enabling the fixed shell 11 to fix the non-regeneration filter cartridge barrel 2 by its own elastic force.

[0078] In some other embodiments, a limiting structure is provided on the fixed shell 11, and the fixed shell 11 fixes the non-regeneration filter cartridge barrel 2 via the limiting structure. For example, the limiting structure is a semicircular protrusion provided on the fixed shell 11, the semicircular protrusion is provided in a groove on the fixed shell 11, and a spring is provided between the bottom wall of the groove and the semicircular protrusion, and the semicircular protrusion is forced to protrude from the surface of the fixed shell 11 by the elastic force of the spring to clamp the non-regeneration filter cartridge barrel 2, and the semicircular protrusion can be forced to retract into the groove on the fixed shell 11 when the non-regeneration filter cartridge barrel 2 is pulled with force.

[0079] In this embodiment, if Figure 5 As shown, the regeneration filter cartridge barrel 3 includes an outer shell 31, a heat-insulating cotton 32 arranged on the outside of the outer shell 31, and a heating element 33 arranged inside the outer shell 31; in the regeneration working state, the heating element 33 is energized to heat the outer shell 31 and the filter element inside the outer shell 31, and the hot and humid air inside the regeneration filter cartridge barrel 3 is carried out through the gas to be filtered inside the regeneration filter cartridge barrel 3.

[0080] In this embodiment, the air inlet and air outlet ends of the non-regeneration filter cartridge barrel 2 and the regeneration filter cartridge barrel 3 are both provided with filter screens 12. By providing filter screens 12 at the air inlet and air outlet ends of the non-regeneration filter cartridge barrel 2 and the regeneration filter cartridge barrel 3, when the gas to be filtered enters the non-regeneration filter cartridge barrel 2 or the regeneration filter cartridge barrel 3 through the air inlet, and when the gas to be filtered leaves the non-regeneration filter cartridge barrel 2 or the regeneration filter cartridge barrel 3 through the air outlet, the filter screens 12 provided at the air inlet and air outlet ends of the non-regeneration filter cartridge barrel 2 and the regeneration filter cartridge barrel 3 can filter the gas to be filtered.

[0081] In this embodiment, if Figure 6 As shown, the single-tube regeneration filter element device also includes a three-way solenoid valve C13, and the three-way solenoid valve C13 is connected to the second air outlet of the regeneration filter element barrel 3.

[0082] Under normal working conditions, the regenerated filter cartridge barrel 3 is connected in series with the non-regenerated filter cartridge barrel 2, and the gas to be filtered is discharged after passing through the regenerated filter cartridge barrel 3 and the non-regenerated filter cartridge barrel 2 in turn. In this state, the gas to be filtered first passes through the regenerated filter cartridge barrel 3, and then enters the non-regenerated filter cartridge barrel 2 after being filtered by the regenerated filter cartridge barrel 3. It can be understood that since the regenerated filter cartridge barrel 3 has completed the filtration of most of the impurities in the gas to be filtered, after the gas reaches the non-regenerated filter cartridge barrel 2, the working intensity of the non-regenerated filter cartridge barrel 2 is reduced. By connecting the regenerated filter cartridge barrel 3 and the non-regenerated filter cartridge barrel 2 in series, the service life of the non-regenerated filter cartridge barrel 2 can be improved. In the regeneration working state, by changing the closing state of the interface of the three-way solenoid valve A4 and the three-way solenoid valve B7, most of the gas to be filtered passes through the non-regeneration filter cartridge barrel 2 alone and then is discharged. At this time, the non-regeneration filter cartridge barrel 2 plays a filtering role on the gas to be filtered, and the regeneration filter cartridge barrel 3 needs to remove impurities inside it. The basic principle of filter cartridge regeneration is to heat the filter cartridge being regenerated and purge a certain flow of gas to discharge moisture out of the system. In this embodiment, the remaining part of the gas to be filtered passes through the heating regeneration filter cartridge barrel 3 alone and then is discharged from the second gas outlet of the regeneration filter cartridge barrel 3 to achieve the above-mentioned gas purge and discharge moisture out of the system. Therefore, in this embodiment, the second gas outlet of the regeneration filter cartridge barrel 3 is connected to a three-way solenoid valve C13. In the normal working state, the three-way solenoid valve C13 closes the second gas outlet of the regeneration filter cartridge barrel 3.

[0083] In this embodiment, the single-tube regeneration filter element device further includes a solenoid valve fixing frame 14 , which is fixed to the base frame 10 , and the three-way solenoid valve A4 , the three-way solenoid valve B7 and the three-way solenoid valve C13 are fixed in parallel on the solenoid valve fixing frame 14 .

[0084] like Figure 1 and Figure 2 In the embodiment shown, the solenoid valve fixing frame 14 is fixed on the front side of the base frame 10, and the solenoid valve fixing frame 14 is fixed with a three-way solenoid valve A4, a three-way solenoid valve B7 and a three-way solenoid valve C13, and the three three-way solenoid valves are placed in parallel. When in use, Figure 6 The method shown connects the three-way solenoid valve A4, the three-way solenoid valve B7 and the three-way solenoid valve C13 with the regeneration filter cartridge barrel 3 and the non-regeneration filter cartridge barrel 2.

[0085] In this embodiment, the single-tube regeneration filter element device also includes a sponge box 15, which is fixed to the solenoid valve fixing frame 14. The interior of the sponge box 15 is suitable for placing sponges, and the end of the pipe connected to the second air outlet of the regeneration filter element barrel 3 is placed in the sponge box 15.

[0086] As described above, in the regeneration working state, in this embodiment, the remaining part of the gas to be filtered is arranged to pass through the heated regeneration filter cartridge barrel 3 separately and then be discharged from the second air outlet of the regeneration filter cartridge barrel 3, so as to realize the above-mentioned gas purge and discharge the moisture from the system. In this embodiment, a sponge box 15 is fixed on the solenoid valve fixing frame 14, a sponge is placed inside the sponge box 15, and the end of the pipe connected to the second air outlet of the regeneration filter cartridge barrel 3 is placed in the sponge box 15. Therefore, after the moisture is discharged from the second air outlet of the regeneration filter cartridge barrel 3, the sponge inside the sponge box 15 can absorb the moisture in the gas.

[0087] In this embodiment, the single-tube regeneration filter element device also includes a temperature and humidity sensor and a pressure sensor, which are configured to detect environmental parameters so as to be suitable for calculating the regeneration cycle parameters of the regeneration filter element barrel 3 based on the measured environmental parameters.

[0088] The single-tube regenerative filter element device provided in this embodiment has a normal working state and a regeneration working state. In the normal working state, the regeneration filter element barrel 3 is connected in series with the non-regeneration filter element barrel 2, and the gas to be filtered passes through the regeneration filter element barrel 3 and the non-regeneration filter element barrel 2 in sequence and is discharged. When the regeneration filter element barrel 3 needs to be regenerated, the single-tube regeneration filter element device enters the regeneration working state, at which time most of the gas to be filtered passes through the non-regeneration filter element barrel 2 alone and is discharged, and the remaining part of the gas to be filtered passes through the heated regeneration filter element barrel 3 alone and is discharged from the second gas outlet of the regeneration filter element barrel 3. Therefore, it is often necessary to manually judge when the regeneration filter element barrel 3 is to be regenerated.

[0089] In this embodiment, a temperature and humidity sensor and a pressure sensor are provided to measure the temperature, humidity, pressure and other parameters of the use environment, and the algorithm is trained according to the environmental parameters to calculate the regeneration cycle parameters that are most suitable for the filter element regeneration in the environment, so as to achieve the maximum efficiency of use. The specific algorithm can be analyzed using existing technology.

[0090] The single-tube regeneration filter element device provided in this embodiment is used as follows: Figure 6 As shown, first, the lower end interface of the three-way solenoid valve B7 is closed, the upper end interface of the three-way solenoid valve A4 is closed, and the upper end interface of the three-way solenoid valve C13 is closed, so that the single-tube regeneration filter element device enters a normal working state. Under the normal working state, after the filtered gas enters the first pipeline 1 from the air inlet, it passes through the three-way connector A5 and the three-way solenoid valve B7 in sequence to reach the regeneration filter element barrel 3, and after being filtered by the regeneration filter element barrel 3, it reaches the three-way solenoid valve A4 from the air outlet of the regeneration filter element barrel 3, and then reaches the non-regeneration filter element barrel 2 through the three-way solenoid valve A4, and is discharged from the air outlet of the non-regeneration filter element barrel 2 after being filtered by the non-regeneration filter element barrel 2.

[0091] When the regeneration filter cartridge barrel 3 needs to be regenerated, the upper interface of the three-way solenoid valve B7 is closed and the lower interface is opened, the upper interface of the three-way solenoid valve A4 is opened and the lower interface is closed, and the upper interface of the three-way solenoid valve C13 is opened and the lower interface is closed. Then the single-tube regeneration filter cartridge device enters the regeneration working state. In the regeneration working state, the gas to be filtered enters the first pipeline 1 from the air inlet of the first pipeline 1. After the gas to be filtered passes through the three-way joint B8, due to the setting of the two-way speed regulating valve 9, most of the gas to be filtered passes through the three-way joint B8 and enters the first pipeline 1, and then reaches the three-way solenoid valve A4 and enters the non-regeneration filter cartridge barrel 2. After being filtered by the non-regeneration filter cartridge barrel 2, it is discharged from the air outlet of the non-regeneration filter cartridge barrel 2. A small part of the gas to be filtered passes through the three-way joint B8, passes through the two-way speed regulating valve 9 and the three-way solenoid valve B7 to reach the regeneration filter cartridge barrel 3. The interior of the regeneration filter cartridge barrel 3 is heated to generate moisture. The small part of the gas to be filtered that reaches the regeneration filter cartridge barrel 3 takes away the moisture generated inside the regeneration filter cartridge barrel 3, flows through the air outlet of the regeneration filter cartridge barrel 3 to the three-way solenoid valve C13, and flows out through the three-way solenoid valve C13.

[0092] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
