[0033] like Figure 1 As shown, some embodiments of the present invention provide a filtering and adsorption device, which is mainly used to filter volatile organic compounds and improve purification efficiency.

[0034] The filtering and adsorption equipment includes a feed hopper 100 , a filtering device 200 and a connecting pipe 500 .

[0035] Along the first direction, a feeding end is provided at one end of the feed hopper 100 so that external adsorption materials can be fed into the feed hopper 100 through the feeding end. In addition, a discharging end is provided at the other end of the feed hopper 100. It can be understood that the adsorption material entering the feed hopper 100 can be discharged through the discharging end.

[0036] In this embodiment, the first direction refers to the vertical direction, that is, the axial direction of the feed hopper 100 .

[0037] The filter device 200 is connected to the discharge end, that is, the adsorption material in the feed hopper 100 can enter the filter device 200 through the discharge end.

[0038] Specifically, the filtering device 200 includes a plurality of filters 210 connected in sequence along the first direction. It is understandable that the number of the filters 210 can be two or more than two arbitrary numerical values, which can be specifically set according to actual conditions.

[0039] In addition, along the second direction, an air inlet pipe 300 and an air outlet pipe 400 are respectively provided on two opposite sides of the filter 210, so that external gas can enter the filter 210 through the air inlet pipe 300, and the volatile organic compounds in the gas are adsorbed by the adsorption material in the filter 210 and then discharged from the air outlet pipe 400, so as to achieve the filtering of the volatile organic compounds in the gas.

[0040] Along the first direction, the adjacent inlet pipe 300 and the outlet pipe 400 are connected through a connecting pipe 500 to define an S-shaped airflow channel, so that a step-by-step adsorption and filtration structure for gas from bottom to top is formed in the filter device 200, which can not only improve the filtration and adsorption efficiency of gas, but also improve the filtration and adsorption quality of gas. In addition, by forming a bottom-up filtration of gas in the filter device 200, the part of the adsorbent material in the filter 210 away from the feed hopper 100 can reach the adsorption saturation state first, that is, the adsorption saturation state of the adsorbent material in the filter 210 decreases from bottom to top, thereby realizing the step-by-step replacement of the adsorbent material in the filter 210 from top to bottom, which can not only ensure that the adsorbent material of each level in the filter 210 can reach the adsorption saturation state, but also improve the utilization rate of the adsorbent material in the filter 210.

[0041] The first direction is perpendicular to the second direction. In this embodiment, the second direction refers to the horizontal direction.

[0042] like Figure 1 As shown, in some embodiments of the present invention, the plurality of filters 210 at least include a first filter 220 , a second filter 230 , a third filter 240 and a fourth filter 250 .

[0043] Along the first direction, a first valve 600 is provided at one end of the first filter 220 away from the second filter 230, so as to limit the adsorption material in the first filter 220 through the first valve 600. When the first valve 600 is closed, the adsorption material in the first filter 220 can remain stable. If the first valve 600 is opened, the adsorption material in the first filter 220 can be discharged from the first valve 600.

[0044] Among them, a second valve 700 is provided between the first filter 220 and the second filter 230, so as to limit the adsorption material in the second filter 230 through the second valve 700. When the second valve 700 is closed, the second valve 700 forms a barrier effect on the adsorption material in the second filter 230 to prevent the adsorption material in the second filter 230 from entering the first filter 220; if the second valve 700 is opened, the adsorption material in the second filter 230 can be discharged from the second valve 700 into the first filter 220, so as to facilitate the replacement of the adsorption material in the first filter 220.

[0045] In addition, a third valve 800 is provided between the second filter 230 and the third filter 240 so as to limit the adsorbent material in the third filter 240 through the third valve 800. When the third valve 800 is closed, the third valve 800 forms a barrier effect on the adsorbent material in the third filter 240 to prevent the adsorbent material in the third filter 240 from entering the second filter 230. If the third valve 800 is opened, the adsorbent material in the third filter 240 can be discharged from the third valve 800 into the second filter 230 to facilitate replacement of the adsorbent material in the second filter 230.

[0046] In this embodiment, a fourth valve 900 is provided between the third filter 240 and the fourth filter 250 so as to limit the adsorption material in the fourth filter 250 through the fourth valve 900. When the fourth valve 900 is closed, the fourth valve 900 forms a barrier effect on the adsorption material in the fourth filter 250 to prevent the adsorption material in the fourth filter 250 from entering the third filter 240. If the fourth valve 900 is opened, the adsorption material in the fourth filter 250 can be discharged from the fourth valve 900 into the third filter 240 to facilitate replacement of the adsorption material in the third filter 240.

[0047] Furthermore, a fifth valve 1000 is provided between the fourth filter 250 and the feed hopper 100. When the fifth valve 1000 is closed, the fifth valve 1000 forms a barrier to the adsorption material in the feed hopper 100, thereby preventing the adsorption material in the feed hopper 100 from entering the fourth filter 250. If the fifth valve 1000 is opened, the adsorption material in the feed hopper 100 can be discharged from the fifth valve 1000 into the fourth filter 250, so as to facilitate the replacement of the adsorption material in the fourth filter 250.

[0048] In this embodiment, the filter device 200 can adsorb volatile organic compounds in the gas, thereby reducing the concentration of organic components in the gas and improving the purification efficiency.

[0049] It should be noted that, in the present embodiment, the air outlet pipe 400 of the first filter 220 is connected to the air inlet pipe 300 of the second filter 230 through the first connecting pipe 510, the air outlet pipe 400 of the second filter 230 is connected to the air inlet pipe 300 of the third filter 240 through the second connecting pipe 520, and the air outlet pipe 400 of the third filter 240 is connected to the air inlet pipe 300 of the fourth filter 250 through the third connecting pipe 530, so as to define an S-shaped airflow channel.

[0050] It is worth noting that the external gas enters the S-shaped air flow channel through the air inlet pipe 300 of the first filter 220, that is, the gas entering the filter device 200 will first flow through the adsorption material located in the first filter 220, and the volatile organic compounds in the gas will be filtered by the adsorption material in the first filter 220. It can be understood that the concentration of volatile organic compounds in the gas entering the first filter 220 is the highest, that is, the adsorption material located in the first filter 220 can reach the adsorption saturation state first.

[0051] Specifically, the external gas passes through the first filter 220 , and after being adsorbed and filtered by the adsorption material in the first filter 220 , it is discharged from the outlet pipe 400 of the first filter 220 into the first connecting pipe 510 , so as to complete the first stage filtration of the gas through the first filter 220 .

[0052] Secondly, the gas after the first stage filtration enters the second filter 230 from the first connecting pipe 510 through the air inlet pipe 300 of the second filter 230, and is filtered and adsorbed by the adsorption material in the second filter 230, and the filtered and adsorbed gas is discharged from the air outlet pipe 400 of the second filter 230 into the second connecting pipe 520 to complete the second stage filtration of the gas.

[0053] Again, the gas after the second stage filtration enters the third filter 240 from the second connecting pipe 520 through the air inlet pipe 300 of the third filter 240, and is adsorbed and filtered by the adsorption material in the third filter 240, and the filtered and adsorbed gas is discharged from the air outlet pipe 400 of the third filter 240 into the third connecting pipe 530 to complete the third stage filtration of the gas.

[0054] Finally, the gas after the third stage filtration enters the fourth filter 250 from the third connecting pipe 530 through the air inlet pipe 300 of the fourth filter 250, and is adsorbed and filtered by the adsorption material in the fourth filter 250, and the filtered and adsorbed gas is discharged from the air outlet pipe 400 of the fourth filter 250 to complete the fourth stage filtration of the gas.

[0055] In summary, the filtering and adsorption device provided by the utility model defines an S-shaped airflow channel from bottom to top in the filtering device 200, so that a step-by-step adsorption and filtration structure for gas from bottom to top is formed in the filtering device 200, which can not only improve the filtering and adsorption efficiency of gas, but also improve the filtering and adsorption quality of gas. In addition, by forming a bottom-up filtration of gas in the filtering device 200, the adsorption material in the first filter 220 can reach the adsorption saturation state first. That is, the adsorption saturation state of the adsorbent materials in the fourth filter 250, the third filter 240, the second filter 230 and the first filter 220 decreases from bottom to top, so that the adsorbent materials in the feed hopper 100 can enter the fourth filter 250 through the fifth valve 1000, the adsorbent materials in the fourth filter 250 can enter the third filter 240 through the fourth valve 900, the adsorbent materials in the third filter 240 can enter the second filter 230 through the third valve 800, the adsorbent materials in the second filter 230 can enter the first filter 220 through the second valve 700, and the adsorbent materials in the first filter 220 can be discharged through the first valve 600, thereby realizing the step-by-step replacement of the adsorbent materials in the filter 210 from top to bottom. In this way, it can not only ensure that the adsorbent materials at each level in the filter 210 can reach the adsorption saturation state, but also improve the utilization rate of the adsorbent materials in the filter 210.

[0056] In addition, the user can adjust the filtration level of the gas in the filter device 200 according to actual conditions to meet the different needs of users and improve the diversity, adjustability and utilization rate of the gas adsorption filtration of the filter adsorption equipment.

[0057] In this embodiment, the volumes of the first filter 220, the second filter 230, the third filter 240 and the fourth filter 250 are equal to ensure the accuracy of the adsorption material during the replacement process and to ensure the consistency of the filtering capabilities of the first filter 220, the second filter 230, the third filter 240 and the fourth filter 250 for volatile organic compounds in the gas.

[0058] It should be noted that the calibers of the air inlet pipe 300, the air outlet pipe 400 and the connecting pipe 500 are equal to ensure the uniformity of gas filtration by each stage of adsorption material in the filter 210, as well as the uniformity of gas filtration capacity of each stage of adsorption material, thereby improving the gas filtration quality and stability.

[0059] That is, the gas entering the filter 210 will not leak from the edge of the second ventilation end, so as to ensure the adsorption and filtration quality of the gas.

[0060] In addition, in some embodiments, a receiving hopper (not shown in the figure) is provided on the side of the first valve 600 facing away from the first filter 220, and the receiving hopper is connected to the first filter 220 through the first valve 600, so that the adsorption material saturated with adsorption in the first filter 220 can be discharged into the receiving hopper through the first valve 600 and recovered through the receiving hopper.

[0061] As shown in the figure, in some embodiments of the present invention, a first detector 1100 is provided on one side of each of the connecting pipes 500 , so as to detect the concentration of volatile organic compounds in the gas flowing through the connecting pipe 500 through the first detector 1100 .

[0062] In addition, along the second direction, the air inlet pipe 300 of the first filter 220 is provided with a second detector 1200 to detect the concentration of volatile organic compounds in the gas before entering the filtering device 200 through the second detector 1200 .

[0063] Specifically, the outlet pipe 400 of the fourth filter 250 is provided with a third detector 1300 to detect the concentration of volatile organic compounds in the gas after the fourth-stage adsorption filtration through the third detector 1300, that is, the concentration of volatile organic compounds in the gas after adsorption by the filter device 200 is detected by the third detector 1300.

[0064] like Figure 1 As shown, in some embodiments of the present invention, the filter 210 includes a mesh frame and an adsorption layer.

[0065] It can be understood that the mesh frame is a porous cylindrical structure, so that external gas can enter the mesh frame through the holes in the outer wall of the mesh frame, that is, the external gas can pass through the mesh frame during the flow.

[0066] The shape of the mesh frame can be a hollow cylindrical shape or a hollow polygonal structure, which can be set according to actual conditions.

[0067] In this embodiment, a screen frame having a hollow cylindrical shape is taken as an example for specific description.

[0068] Specifically, the mesh frame has a guide channel, the axis of which coincides with the axis of the mesh frame, and the adsorption layer is disposed in the guide channel to form a filter 210 .

[0069] It should be noted that the adsorption layer is the adsorption material described in the above embodiment, that is, the adsorption layer is formed in the guide channel of the screen frame by adding the adsorption material into the guide channel of the screen frame.

[0070] It can be understood that since the outer wall of the filter 210 is a mesh frame, the gas can effectively enter the mesh frame through the holes on the mesh frame and contact the adsorption layer, and the volatile organic compounds in the gas are adsorbed by the adsorption layer, thereby achieving filtration of volatile organic compounds.

[0071] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0072] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0073] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
