Description

Technical Field

[0001] This utility model relates to the field of gas purification technology, and in particular to a dry demisting filter device. Background Technology

[0002] Dry demisting filter boxes, also known as water vapor separation exhaust gas demisting boxes, are mainly used to prevent water mist from spray towers and scrubbing towers from being drawn into subsequent treatment equipment by the fan, so as to intercept water mist and various particulate matter.

[0003] Traditional dry demisting filter boxes often use fiber structures for filtration. This filter-like method can become clogged due to the accumulation of pollutants after long-term use, resulting in a decrease in filtration efficiency. This necessitates frequent cleaning or replacement of the filter media. Furthermore, because the filter box lacks a proper barrier structure, even after demisting filtration is completed, some moisture will still be discharged from the exhaust pipe along with the gas, indicating incomplete water vapor separation. Utility Model Content

[0004] Those skilled in the art have provided a dry demisting filtration device to solve the problems mentioned in the background art.

[0005] To solve the above technical problems, this utility model provides a dry demisting filter device, including a housing shell. An air inlet pipe is fixedly installed in the middle of the left end face of the housing shell for the intake of exhaust gas. An exhaust pipe is fixedly installed in the middle of the upper end face of the housing shell for the discharge of filtered gas after impurities in the exhaust gas. A water pipe is fixedly installed in the middle of the lower end face of the housing shell for the discharge of filtered water and harmful substances mixed in the water.

[0006] A baffle plate is provided at the upper part of the hollow cavity inside the outer shell of the box. The side extension of the baffle plate is arc-shaped. Connecting plates are fixedly installed at both ends of the baffle plate. Multiple connecting plates will fix the baffle plate to the inner wall of the outer shell of the box.

[0007] A first baffle plate is fixedly installed in the middle of the hollow cavity inside the outer shell of the box, and a second baffle plate is fixedly installed at the bottom of the hollow cavity inside the outer shell of the box. A filter chamber is formed between the second baffle plate and the first baffle plate. Several multifaceted hollow spheres are placed in the filter chamber. A spherical end is provided in the middle of the filter chamber. Several through holes are opened on the spherical end. A conduit is fixedly installed on the left end of the spherical end. The conduit passes the exhaust gas connected to the air inlet pipe into the spherical end and fills the filter chamber with exhaust gas through several through holes. The centrifugal force generated by the rotating multifaceted hollow spheres increases the gas-liquid contact area, thereby completing gas-liquid separation.

[0008] In a preferred embodiment: a viewing window is provided at the bottom of the front end face of the outer shell of the box. The window of the viewing window is fixed with a transparent plastic plate by a number of PP screws, so as to facilitate observation of the stains adhering to the multi-faceted hollow spheres inside the box, thereby determining whether to replace the multi-faceted hollow spheres.

[0009] In a preferred embodiment: an annular plate is fixedly installed at the lower end of the side extension of the barrier plate. The annular plate is parallel to the inner wall of the housing shell, and a guide cavity is formed between the annular plate and the inner wall of the housing shell. The filtered gas after filtering impurities in the exhaust gas can be guided from the guide cavity to the exhaust pipe end.

[0010] In a preferred embodiment: triangular strips are fixedly installed on the lower sides of both the left and right ends of the fence baffle. The inclined surface of the triangular strip is an arc surface, and the width of the triangular strip is greater than the width of the guide cavity. Thus, the filtered air that has completed the filtration of impurities will be guided by the arc surface of the triangular strip to the bottom of the baffle plate to wait for air accumulation. After the air accumulation is completed, the filtered air is discharged from the guide cavity to the exhaust pipe end by air pressure.

[0011] In a preferred embodiment: the second baffle plate forms a water accumulation cavity with the bottom of the hollow cavity inside the outer shell of the box, and the bottom of the hollow cavity inside the outer shell of the box is set as an inclined surface to guide to the end of the water pipe, so that the separated liquid and its impurities can be guided out.

[0012] In a preferred embodiment: the top of the hollow cavity inside the housing is configured as an inclined surface that guides the gas to the exhaust pipe end, so that the separated gas can be guided out.

[0013] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0014] 1. When this utility model is used, multiple multi-faceted hollow spheres are used to replace the traditional filter material for gas-liquid separation. The multiple multi-faceted hollow spheres are used to generate centrifugal force by blowing and rotating the high-pressure exhaust gas. The structure of the multi-faceted hollow spheres increases the contact area between gas and liquid, thus completing gas-liquid separation. This can prevent the problem of impurities in the exhaust gas clogging the filter material and affecting the working efficiency of gas-liquid separation.

[0015] 2. When this utility model is used, by adding a triangular strip at the lower end of the fence baffle to form a meandering gas deposition circuit with the barrier plate and the annular plate, the bottom of the barrier plate serves as a gas volume limiting surface, allowing the moisture carried by the separated gas to fall off under the influence of gravity, further blocking impurities carried by the filtered gas and increasing the filtration effect.

For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] Please see Figures 1-3This embodiment provides a dry demisting filter device, including a housing shell 1. A viewing window 2 is provided at the bottom of the front end face of the housing shell 1. The window of the viewing window 2 is fixed with a transparent plastic plate by several PP screws, which facilitates observation of the dirt adhesion of the multi-faceted hollow spheres 12 inside the housing, thereby determining whether to replace the multi-faceted hollow spheres 12. An air inlet pipe end 3 is fixedly installed in the middle of the left end face of the housing shell 1. The air inlet pipe end 3 is used for the intake of exhaust gas. An exhaust pipe end 4 is fixedly installed in the middle of the upper end face of the housing shell 1. The exhaust pipe end 4 is used for the discharge of filtered air after filtering impurities in the exhaust gas. A water pipe end 5 is fixedly installed in the middle of the lower end face of the housing shell 1. The water pipe end 5 is used for the discharge of water and harmful substances mixed in the water after filtering the water in the exhaust gas.

[0024] A baffle plate 6 is provided on the upper part of the hollow cavity inside the housing 1. The side extension of the baffle plate 6 is arc-shaped. Connecting plates 7 are fixedly installed on both the left and right ends of the baffle plate 6. Multiple connecting plates 7 will fix the baffle plate 6 to the inner wall of the housing 1. An annular plate 8 is fixedly installed on the lower end of the side extension of the baffle plate 6. The annular plate 8 is parallel to the inner wall of the housing 1, so that a guide cavity 9 is formed between the annular plate 8 and the inner wall of the housing 1. The filtered gas after filtering impurities in the exhaust gas can be guided from the guide cavity 9 to the exhaust pipe end 4.

[0025] A first baffle plate 10 is fixedly installed in the middle of the hollow cavity inside the outer shell 1. Triangular strips are fixedly installed on the lower sides of both ends of the first baffle plate 10. The inclined surfaces of the triangular strips are arc-shaped, and the width of the triangular strips is greater than the width of the guide cavity 9. Thus, the filtered air that has completed the filtration of impurities will be guided by the arc-shaped surfaces of the triangular strips to the bottom of the baffle plate 6 to wait for air accumulation. After the air accumulation is completed, the filtered air is discharged from the guide cavity 9 to the exhaust pipe end 4 by air pressure. A second baffle plate 11 is fixedly installed at the bottom of the hollow cavity inside the outer shell 1. A filter cavity is formed between the second baffle plate 11 and the first baffle plate 10. Several multi-faceted hollow spheres 12 are placed in the filter cavity. A spherical end 14 is provided in the middle of the filter cavity. The upper part has several through holes 15. The left end of the spherical end 14 is connected to and fixedly installed with a conduit 13. The conduit 13 introduces the exhaust gas connected to the air inlet pipe 3 into the spherical end 14, and fills the filter chamber with exhaust gas through several through holes 15. The centrifugal force generated by the rotating multi-faceted hollow spheres 12 increases the contact area between gas and liquid, thereby completing gas-liquid separation. The second baffle plate 11 and the bottom of the hollow cavity inside the outer shell 1 form a water accumulation cavity. The bottom of the hollow cavity inside the outer shell 1 is set as an inclined surface to guide to the water pipe end 5, so that the separated liquid and its impurities can be guided out. The top of the hollow cavity inside the outer shell 1 is set as an inclined surface to guide to the exhaust pipe end 4, so that the separated gas can be guided out.

[0026] The working principle of this utility model is as follows:

[0027] In use, the exhaust gas is fed into the spherical end 14 through the inlet pipe 3 and the conduit 13. The exhaust gas will fill the filter chamber through multiple through holes 15. At this time, multiple multifaceted hollow spheres 12 will rotate under the blowing of high-pressure exhaust gas, forming centrifugal force. The structure of the multifaceted hollow spheres 12 increases the gas-liquid contact area, thus completing gas-liquid separation. Using multiple multifaceted hollow spheres 12 instead of traditional filter media for gas-liquid separation can prevent the problem of impurities in the exhaust gas clogging the filter media and affecting the working efficiency of gas-liquid separation. At the same time, the triangular strip at the lower end of the baffle plate 10, together with the barrier plate 6 and the annular plate 8, forms a meandering gas deposition circuit. The bottom of the barrier plate 6 serves as a gas volume limiting surface, allowing the moisture carried by the separated gas to fall off under the influence of gravity, further blocking impurities carried by the filtered gas and increasing the filtration effect.

[0028] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
