Description

Technical Field

[0001] This utility model relates to the field of gas treatment technology, and in particular to a separator and gas treatment equipment for gas treatment. Background Technology

[0002] The large amounts of flue gas generated by factories need to be treated and purified before being discharged. Generally, the flue gas treatment method involves feeding the generated flue gas into a flue gas treatment tower, where it undergoes wet treatment before being discharged outside the tower. Some existing flue gas treatment towers also have internal separators, or dust collectors and demisters, to separate particles and droplets from the flue gas before it is discharged outside the tower, further purifying the flue gas.

[0003] Currently, baffles or swirl plates are commonly used to remove larger droplets, but this method is usually inefficient and requires a large separator. For finer droplets, electrode adsorption is typically used for separation, which necessitates additional electrical components, resulting in a more complex separator structure and higher installation costs. Utility Model Content

[0004] One objective of this invention is to provide a separator and gas processing equipment for gas processing that can solve any of the above-mentioned problems.

[0005] Specifically, this utility model provides a separator for gas treatment, comprising:

[0006] Multiple separation structures are stacked and spaced apart from adjacent structures. Each separation structure includes multiple inclined plates, with two opposite sides of each inclined plate designated as the head and tail ends. The inclined plates are connected sequentially head-to-tail, with adjacent inclined plates tilting in opposite directions. Each inclined plate has multiple through holes to allow gas to pass sequentially through the stacked separation structures.

[0007] Multiple guide structures are provided on the surface of each inclined plate. The guide structures are provided on the surface of the corresponding inclined plate opposite to the smoke inlet side, and each guide structure corresponds to a through hole. The projection of the guide structure on the surface of the inclined plate at least partially covers the corresponding through hole. The guide structure forms an outlet. In the distribution direction of the multiple separation structures, the outlets on the same separation structure face the same direction, and the outlets on two adjacent separation structures face opposite directions.

[0008] Optionally, the axis of the outlet formed by the guide structure is parallel to the surface of the inclined plate and extends along the inclination direction of the inclined plate.

[0009] Optionally, the guide structure has a bent surface on the side facing the through hole, the concave side of the bent surface facing the through hole, and the bent surface extends from the surface of the inclined plate where the guide structure is located to the outlet.

[0010] Optionally, the projection of the guide structure onto the surface of the inclined plate completely covers the corresponding through hole.

[0011] Optionally, the outlet is fitted to the surface of the inclined plate.

[0012] Optionally, the separation structure includes four inclined plates, and along the distribution direction of the four inclined plates, the first and last inclined plates extend to the same length along the inclined direction, the middle two inclined plates extend to the same length along the inclined direction, and the first and last inclined plates extend to a greater length along the inclined direction than the middle two inclined plates.

[0013] Optionally, all the through holes on two adjacent separation structures are staggered along the distribution direction of the plurality of separation structures.

[0014] Optionally, the porosity of each of the inclined plates in the separation structure is set to...

[0015] Optionally, the distance between two adjacent separation structures is set to

[0016] In another aspect of this utility model, a gas processing device is also provided, comprising:

[0017] An outer casing having a processing chamber, and an air inlet and an air outlet communicating with the processing chamber; and

[0018] According to any of the preceding claims, the separator is disposed within the processing chamber and located between the air inlet and the air outlet, such that gas entering the processing chamber from the air inlet passes through the separator before flowing to the air outlet.

[0019] This utility model discloses a gas separator and gas treatment equipment that utilizes a stacked arrangement of multiple separation structures. Each separation structure comprises multiple inclined plates connected end-to-end. Each inclined plate has multiple through holes and multiple guide structures on its surface. The guide structures are located on the surface of the corresponding inclined plate opposite to the smoke inlet side, and each guide structure corresponds to one through hole. The projection of the guide structure onto the surface of its respective inclined plate at least partially covers the corresponding through hole. Each guide structure has an outlet, and in the distribution direction of the multiple separation structures, the outlets on the same separation structure face the same direction, while the outlets on adjacent separation structures face opposite directions. Therefore, as gas flows through the separator along the distribution direction of the separation structures, gas passing through the through holes on one side of the separation structure is blocked by the guide structures, thus changing direction and flowing to the other side of the separation structure through the outlet. During the sequential passage through multiple separation structures, some particles and droplets in the gas are adsorbed onto the separation structures. Furthermore, due to the change in gas flow path, particles and droplets are more easily retained, thereby separating the particles and droplets. This process requires no electricity, reducing installation costs. Meanwhile, in the distribution direction of multiple separation structures, the outlets on two adjacent separation structures face opposite directions, which causes the gas to change direction differently when passing through two adjacent separation structures, thus helping to improve the separation effect of particles and droplets.

[0029] like Figure 1 As shown, in one embodiment, the gas processing device includes a housing 100 and a separator 200. The housing 100 forms a processing chamber 101, and an inlet 102 and an outlet 103 communicating with the processing chamber 101. The separator 200 is disposed within the processing chamber 101 and located between the inlet 102 and the outlet 103, so that gas entering the processing chamber 101 from the inlet 102 passes through the separator 200 before flowing to the outlet 103, thereby separating particles and droplets from the gas by the separator 200.

[0030] It should be noted that, although not shown in the figure, the gas processing equipment also includes a spray structure installed in the processing chamber 101 for spraying a reaction solution that reacts with the gas into the processing chamber 101. The spray structure is located between the gas inlet 102 and the separator 200.

[0031] The separator 200 is the separator 200 of any of the following embodiments.

[0032] like Figures 2 to 4 As shown, in one embodiment, the separator 200 includes three plate-shaped separation structures 210, which are stacked and spaced apart from each other. Each separation structure 210 includes four inclined plates 220, with the two opposite sides of each inclined plate 220 designated as the head end and tail end. The multiple inclined plates 220 are connected sequentially in a head-to-tail manner, and the inclination directions of adjacent inclined plates 220 are opposite. Each inclined plate 220 is provided with multiple through holes 201, so that gas can pass through the multiple stacked separation structures 210 sequentially through the through holes 201. And a plurality of guide structures 230 are provided on the surface of each inclined plate 220. The guide structures 230 are provided on the surface of the corresponding inclined plate 220 away from the smoke inlet side and each guide structure 230 corresponds to a through hole 201. The projection of the guide structure 230 on the surface of the inclined plate 220 at least partially covers the corresponding through hole 201. The guide structure 230 forms an outlet 202. In the distribution direction of the plurality of separation structures 210, the outlets on the same separation structure 210 face the same direction, and the outlets on two adjacent separation structures 210 face opposite directions.

[0033] Reference Figure 3 As shown, specifically, multiple separation structures 210 are stacked longitudinally. Each separation structure 210 includes four inclined plates 220, which are distributed in the left-right direction. Starting from the left, the first inclined plate 220 is inclined from the lower left to the upper right, the second inclined plate 220 is inclined from the upper left to the lower right, the third inclined plate 220 is inclined from the lower left to the upper right, and the fourth inclined plate 220 is inclined from the upper left to the lower right. In other words, the separation structure 210 is roughly "M" shaped.

[0034] like Figures 2 to 4 As shown, each inclined plate 220 is provided with multiple through holes 201. Gas can flow from one side of the inclined plate 220 to the opposite side through the through holes 201. In other words, for two adjacent separation structures 210, gas can enter between the two separation structures 210 through the through holes 201 on any one of the inclined plates 220 of the first contacting separation structure 210.

[0035] Reference Figures 2 to 4 As shown, each inclined plate 220 has multiple guide structures 230 on its surface. The guide structures 230 are located on the surface of the corresponding inclined plate 220 facing away from the smoke inlet side, and each guide structure 230 corresponds to a through hole 201. Specifically, during the gas processing process of the separator 200, the gas passes through multiple separation structures 210 sequentially. Therefore, for the inclined plate 220, the side where the gas enters its through hole 201 is the smoke inlet side of the inclined plate 220. Figure 1As shown, after the gas enters the processing chamber 101 through the air inlet 102, it passes through multiple separation structures 210 in sequence. Therefore, the bottom side of each inclined plate 220 is the smoke inlet side, and the guide structure 230 is set on the top side of each inclined plate 220.

[0036] Continue to refer to Figures 2 to 4 As shown, the guide structure 230 is a shell-like structure that protrudes from the surface of the inclined plate 220 and at least partially covers the through hole 201. The portion of the guide structure 230 that adheres to the inclined plate 220 at least partially surrounds the through hole 201, and the projection of the portion protruding from the surface of the inclined plate 220 onto the surface of the adjacent inclined plate 220 completely covers the corresponding through hole 201. The guide structure 230 has an outlet 202, and in the distribution direction of the plurality of separation structures 210, the outlets 202 on the same separation structure 210 face the same direction, while the outlets on adjacent separation structures 210 face opposite directions. In other words, the component of the orientation of the outlet on the same separation structure 210 in the distribution direction of the plurality of separation structures 210 faces the same direction, while the component of the orientation of the outlets on adjacent separation structures 210 faces opposite directions. Figure 1 and Figure 3 As shown, multiple separation structures 210 are distributed along the vertical direction, so the components of the outlet 202 on the same separation structure 210 in the vertical direction are oriented in the same direction, while the components of the outlet 202 on two adjacent separation structures 210 in the vertical direction are oriented in opposite directions.

[0037] Because the guide structure 230 covers the through hole 201, the axis of the outlet 202 intersects the axis of the through hole 201. In other words, the gas passing through the through hole 201 from one side of the inclined plate 220 will change its flow direction due to the obstruction of the guide structure 230, and then finally flow from the outlet 202 to the other side of the inclined plate 220.

[0038] It should be noted that, for ease of illustration, only some of the through holes and guide structures are shown in the figure.

[0039] Combination Figures 1 to 4As shown, specifically, during the gas processing, gas enters the processing chamber 101 through the inlet 102, then flows upward within the processing chamber 101, reacting with the reaction solution during this process, and then flows to the separator 200. The gas first passes through the lowermost separation structure 210, and the gas passing through the through-hole 201 is blocked by the guide structure 230, thus changing direction and flowing diagonally downwards, finally flowing through the outlet 202 between the lowermost and middle separation structures 210. Then, the gas passes through the through-hole 201 on the middle separation structure 210; similarly, the gas passing through the through-hole 201 is blocked by the guide structure 230, changing direction and flowing diagonally upwards, finally flowing through the outlet 202 between the middle and uppermost separation structures 210. Then, the gas passes through the through hole 201 on the uppermost separation structure 210. The gas passing through the through hole 201 is blocked by the guide structure 230, changes direction and flows diagonally downward, and finally flows from the outlet 202 to the space between the uppermost separation structure 210 and the outlet 103. Finally, the gas flows out of the processing chamber 101 from the outlet 103.

[0040] In this embodiment, multiple separation structures 210 are stacked and arranged. Each separation structure 210 includes multiple inclined plates 220 connected end-to-end. Each inclined plate 220 has multiple through holes 201, and each inclined plate 220 has multiple guide structures 230 on its surface. The guide structures 230 are disposed on the surface of the corresponding inclined plate 220 away from the smoke inlet side, and each guide structure 230 corresponds to one through hole 201. The projection of the guide structure 230 on the surface of the inclined plate 220 at least partially covers the corresponding through hole 201. The guide structure 230 forms an outlet 202. In the distribution direction of the multiple separation structures 210, the outlets on the same separation structure 210 face the same direction, and the outlets on two adjacent separation structures 210 face opposite directions. Therefore, as the gas flows through the separator 200 along the distribution direction of the separation structures 210, the gas passing through the through hole 201 from one side of the separation structure 210 will be blocked by the guide structure 230, thereby changing direction and flowing to the other side of the separation structure 210 through the outlet 202. As the gas flows through multiple separation structures 210, some particles and droplets in the gas are adsorbed onto the separation structures 210. Because the gas flow path changes, particles and droplets are more easily retained, thus separating them from the gas without the need for electricity, reducing installation costs. Furthermore, when particles or droplets pass through the guide structure 230 on the separation structure 210, their flow direction changes on the surface of the guide structure 230, making them more easily thrown onto the surface of the guide structure 230 by inertia, achieving a partial removal effect. Simultaneously, in the distribution direction of the multiple separation structures 210, the outlets of adjacent separation structures 210 face opposite directions, causing the gas to undergo different changes in direction when passing through adjacent separation structures 210, which helps to improve the separation effect of particles and droplets.

[0041] In addition, by ensuring that the projection of the guide structure 230 onto the surface of the inclined plate 220 completely covers the corresponding through hole 201, the ability of the guide structure 230 to change the gas flow direction is optimized, resulting in a better separation effect.

[0042] It should be noted that in some other embodiments of this application, the separator may also include two, four, or more separation structures. Additionally, the separation structure may include two, three, five, or more inclined plates. Alternatively, the projection of the guide structure onto the surface of the inclined plate may partially cover the corresponding through-hole; that is, the projection of the guide structure onto the surface of the inclined plate at least partially covers the corresponding through-hole.

[0043] Additionally, it should be noted that the guide structure can be integrally formed with the inclined plate or formed separately and then fixed to the inclined plate.

[0044] like Figures 2 to 4As shown, in one embodiment, the axis of the outlet 202 formed by the guide structure 230 is parallel to the surface of the inclined plate 220 and extends along the inclined direction of the inclined plate 220. The outlet 202 is in contact with the surface of the inclined plate 220.

[0045] Reference Figure 3 and Figure 4 As shown, specifically taking the leftmost inclined plate 220 of the bottommost separation structure 210 as an example, the inclined plate 220 is inclined in the direction of lower left to upper right, and the outlet 202 faces lower left, that is, the axial extension direction of the outlet 202 is also lower left to upper right. In addition, the outlet 202 formed by the guide structure 230 is a non-closed outlet 202 with a notch, and the notch of the outlet 202 is attached to the surface of the inclined plate 220, so that the surface of the inclined plate 220 closes the notch of the outlet 202.

[0046] By making the axis of the outlet 202 parallel to the surface of the inclined plate 220 and making the outlet 202 fit against the surface of the inclined plate 220, the flow direction of the gas flowing out of the outlet 202 is more closely aligned with the plane of the inclined plate 220, which further facilitates the diffusion of gas on the surface of the inclined plate 220 and improves the adsorption effect of the inclined plate 220 surface on particles and droplets in the gas.

[0047] like Figures 2 to 4 As shown, in one embodiment, along the distribution direction of the four inclined plates 220, the first and last inclined plates 220 extend to the same length in the inclined direction, the middle two inclined plates 220 extend to the same length in the inclined direction, and the first and last inclined plates 220 extend to the same length in the inclined direction than the middle two inclined plates 220 extend to the same length in the inclined direction.

[0048] Reference Figures 2 to 4 As shown, taking the bottommost separation structure 210 as an example, the four inclined plates 220 are distributed in the left and right directions. The first and last two inclined plates 220, namely the leftmost and rightmost inclined plates 220, extend in the inclined direction for the same length. The middle two inclined plates 220, namely the second and third from the left, extend in the inclined direction for the same length. Moreover, the leftmost and rightmost inclined plates 220 extend in the inclined direction for a longer length than the second and third from the left inclined plates 220. In other words, the bottom side of the second and third inclined plates 220 from the left is higher than the bottom side of the leftmost and rightmost inclined plates 220.

[0049] By arranging the four inclined plates 220 along their distribution direction, ensuring that the first and last inclined plates 220 extend to the same length along the inclined direction, and that the two middle inclined plates 220 extend to the same length along the inclined direction, while the first and last inclined plates 220 extend to a length greater than the two middle inclined plates 220, the first and last inclined plates 220 form a tapering region, increasing the gas flow velocity. Simultaneously, the connecting sides of the two middle inclined plates 220 bulge towards the gas, causing the gas to disperse upon impact. This enhances the collision effect between the gas and the separation structure 210 as a whole, facilitating better separation of particles and droplets in the gas.

[0050] like Figure 3 and Figure 4 As shown, all the through holes 201 on two adjacent separation structures 210 are staggered along the distribution direction of the multiple separation structures 210. Specifically, the multiple separation structures 210 are distributed vertically, meaning that the through holes 201 of two adjacent separation structures 210 do not coincide at the vertical line at their center. This makes the gas flow path more complex, improves the contact and collision effect between the gas and the separation structures 210, and is beneficial for better separation of particles and droplets in the gas.

[0051] Reference Figure 3 and Figure 4 As shown, in one embodiment, the porosity of each inclined plate 220 in the separation structure 210 is set to 10% to 40%. Specifically, the ratio of the volume removed by each inclined plate 220 to form the through hole 201 to the volume of the remaining solid part is 10% to 40%. For example, it can be 10%, 15%, 20%, 25%, 30%, 35%, or 40%, etc., so as to ensure that the inclined plate 220 has good structural strength while ensuring good gas processing efficiency.

[0052] Reference Figure 3 and Figure 4 As shown, in one embodiment, the distance between two adjacent separation structures 210 is set to 10mm to 100mm. Specifically, the distance between the two surfaces corresponding to the two separation structures 210 along the distribution direction is set to 10mm to 100mm. For example, it can be 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, or 100mm, etc., so that the distance between two adjacent separation structures 210 is more appropriate, avoiding excessive space occupation due to being too far apart, and avoiding poor gas flow due to being too close.

[0053] In addition, the thickness of each inclined plate 220 is set from 0.09mm to 2.00mm, for example, it can be 0.09mm, 0.10mm, 0.20mm, 0.30mm, 0.40mm, 0.50mm, 0.60mm, 0.70mm, 0.80mm, 0.90mm, 1.00mm, 1.10mm, 1.20mm, 1.30mm, 1.40mm, 1.50mm, 1.60mm, 1.70mm, 1.80mm, 1.90mm or 2.00mm, etc., to ensure the separation effect while avoiding the separator 200 from being too bulky and costly.

[0054] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
