Description

Technical Field

[0001] The invention belongs to the field of equipment for realizing reverse contact between gas phase and solid phase, and relates to equipment for realizing reverse contact between gas phase and solid phase and its distribution funnel, and the equipment is particularly suitable for countercurrent activated carbon desulfurization. Background Art

[0002] In the field of industrial production, it is often necessary to use solid materials to contact with gases, so that various reactions occur between the gases and materials. In order to make the materials and gases fully contact, granular materials can be used to contact and react with the gases. For example, the most common method is to use activated carbon to adsorb and treat various industrial waste gases to be treated, thereby purifying the gases to be treated and meeting environmental protection requirements.

[0003] Generally in the prior art, when the gas to be treated is brought into contact and reacted with a material, the material is generally evenly distributed within a certain area, and then the gas to be treated is directly introduced into the area. For example, a reaction chamber can be established in the equipment, and the material is flatly loaded in the reaction chamber, and then the gas to be treated is introduced into the reaction chamber so that the gas and the material are brought into contact and react.

[0004] Since the gas to be treated is directly introduced into the material, the distribution of the gas to be treated in the material is not uniform, and the gas to be treated cannot be fully and evenly contacted with all the materials, which reduces the utilization rate of the materials and increases the cost. For example, the surface layer of the flat material can be fully contacted with the gas to be treated, but the material in the inner layer may only contact less gas to be treated, which reduces the utilization rate of the inner layer material.

[0005] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Summary of the invention

[0029] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0030] In the description of the present invention, the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention rather than requiring the present invention to be constructed and operated in a specific orientation, so it should not be construed as a limitation to the present invention. The terms "connected" and "connected" used in the present invention should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be directly connected or indirectly connected through an intermediate component. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0031] According to an embodiment of the present invention, as Figures 1 to 7As shown, an embodiment of the present invention provides a cloth funnel 1, which includes an upper funnel 2 and a lower funnel 3. The top opening of the upper funnel 2 is larger than the bottom opening of the upper funnel 2. The upper funnel 2 is arranged above the lower funnel 3, and the bottom opening of the upper funnel 2 corresponds to the top opening of the lower funnel 3. The horizontal projection plane of the bottom opening of the upper funnel 2 is located within the horizontal projection plane of the top opening of the lower funnel 3, and there is a gap between the upper funnel 2 and the lower funnel 3, and this gap forms an air inlet. Gas enters the upper funnel 2 and the lower funnel 3 through the air inlet between the upper funnel 2 and the lower funnel 3, and is uniformly mixed with the solid materials in the upper funnel 2 and the lower funnel 3. Figure 1 and Figure 5 The arrow in

[0032] The following takes the countercurrent method of activated carbon desulfurization as an example to illustrate the use process of the cloth funnel 1. The device for realizing the reverse contact between the gas phase and the solid phase and its cloth funnel in the embodiment of the present invention can also be used in other cases where granular or powdery materials are in reverse contact with gaseous materials. When in use, the activated carbon above enters through the top opening of the upper funnel 2, flows into the top opening of the lower funnel 3 through the bottom opening of the upper funnel 2, and finally is discharged through the bottom opening of the lower funnel 3. Since the horizontal projection plane of the bottom opening of the upper funnel 2 is located within the horizontal projection plane of the top opening of the lower funnel 3, the activated carbon will not overflow from the top opening of the lower funnel 3 when falling. While the activated carbon is falling, gas enters the space below the cloth funnel 1 and enters the cloth funnel 1 through the air inlet formed by the gap between the upper funnel 2 and the lower funnel 3, so as to fully mix and react with the falling activated carbon, improving the utilization rate of the materials.

[0033] The funnel is composed of a first side, a second side, a third side, and a fourth side that are connected in sequence circumferentially. Both the first side and the third side are formed by an upper funnel plate 5 and a lower funnel plate 6. The second side and the fourth side are formed by a second side plate and a fourth side plate respectively. Cuts 7 are provided on both the second side plate and the fourth side plate. The side plates at the cuts 7 are bent inward and connected (such as welded) to the adjacent upper funnel plate 5 to form the upper layer funnel 2. Specifically: three slits are cut at appropriate positions on the side plates. The three slits include a horizontal slit and two inclined slits of the same length. The bottom ends of the two inclined slits are respectively connected to the two ends of the horizontal slit. The angles between the two inclined slits and the horizontal slit are the same and are both obtuse angles. The side plate within the area enclosed by the three slits (which can be called a baffle) is bent inward along the connecting line of the top ends of the two inclined slits, so that the two hypotenuses of the baffle are attached to and welded and sealed with the adjacent upper funnel plate 5; a gap is generated between the bottom edge of the baffle and the side plate, facilitating gas to enter the cloth funnel 1 from this gap. The lower funnel plate 6 is connected to the second side plate and the fourth side plate. The area between the upper edge and the lower edge of the lower funnel plate 6 forms the lower layer funnel 3. During use, since both the second side plate and the fourth side plate are connected to the upper funnel plate 5 and the lower funnel plate 6, they play a connecting role, making the connection between the upper layer funnel 2 and the lower layer funnel 3 stable and facilitating production and manufacturing.

[0034] In some embodiments of the present invention, the material of the side plates forming the first side, the second side, the third side, and the fourth side is steel, such as Q235 steel plates.

[0035] Furthermore, the top opening of the lower layer funnel 3 is larger than the bottom opening of the lower layer funnel 3. Such a design can, on the premise of ensuring a certain size of the bottom opening of the cloth funnel 1 (i.e., the bottom opening of the lower layer funnel 3) (the purpose is to ensure the material leakage efficiency), as much as possible expand the size of the top opening of the lower layer funnel 3 (since the inclination of the side of the cloth funnel 1 is generally fixed, the higher the height of the lower layer funnel 3, the larger the size of its top opening), so that the gap area between the top opening of the lower layer funnel 3 and the upper layer funnel 2 is larger, which is more conducive to the entry of gas.

[0036] In order to further prevent the activated carbon from overflowing from the top opening of the lower layer funnel 3, the upper edge of the lower funnel plate 6 is located above the lower edge of the upper funnel plate 5.

[0037] Furthermore, the upper funnel plate 5 and the lower funnel plate 6 on the same side of the cloth funnel 1 are arranged in parallel.

[0038] Further, it further includes a secondary gas distributor 9 (or a secondary gas distribution component). The secondary gas distributor 9 is arranged inside the upper funnel 2, above the bottom opening of the upper funnel 2. The secondary gas distributor 9 includes at least one dividing portion 10. The dividing portion 10 includes two inclined panels. The vertices of the two inclined panels are connected to form a V-shaped groove with the opening facing downward. The two end portions of the dividing portion 10 are respectively connected to the inner wall of the upper funnel 2, dividing the upper funnel 2 into at least two falling openings. During use, the inclined panels of the dividing portion 10 and the inner wall (which is also an inclined surface) of the upper funnel 2 form a new small funnel shape one by one, which is equivalent to dividing the inner area of the upper funnel 2 into multiple small funnels. In this way, the activated carbon can fall evenly at multiple points, which is conducive to the contact between the gas and the activated carbon, and avoids the accumulation of activated carbon in the upper funnel 2, so that the activated carbon in its inner layer cannot contact or is not fully contacted with the gas. The V-shaped dividing portion 10 can be formed by simply bending a strip-shaped plate, such as a strip-shaped stainless steel plate, along the midline to form a V shape during processing; it is easy to process and saves materials.

[0039] Further, the secondary gas distributor 9 includes two dividing portions 10. The two dividing portions 10 are cross-connected, such as cross-connected in a cross shape, dividing the upper funnel 2 into four falling openings.

[0040] Further, the secondary gas distributor 9 is arranged at the top opening of the upper funnel 2, and the top of the secondary gas distributor 9 is flush with the top of the upper funnel 2.

[0041] The embodiment of the present invention further provides a cloth funnel layer using the above cloth funnel 1. The cloth funnel layer is arranged inside the adsorption tower, dividing the adsorption tower into upper and lower layers. Specifically, the frame of the cloth funnel layer (the frame formed by the upper edges of the two through-length plates 8 and the upper edges of the upper funnels 2 on both sides) is tightly connected to the inner wall of the adsorption tower. It is also possible to arrange multiple cloth funnel layers in an array inside the adsorption tower according to the width of the adsorption tower, thereby dividing the adsorption tower into upper and lower layers. The cloth funnel layer includes multiple cloth funnels 1. The multiple cloth funnels 1 are connected to each other in the horizontal direction and are arranged in an array; the second side panels of the multiple cloth funnels 1 are coplanar and are an integral structure, and the fourth side panels of the multiple cloth funnels 1 are coplanar and are an integral structure; for example, two through-length plates 8 can be respectively used as the common second side panel and the fourth side panel of the multiple cloth funnels 1. As the support of the entire cloth funnel layer, since two of the sides of the multiple cloth funnels 1 share a whole through-length plate 8, it not only saves materials, avoids cutting waste, but also increases the connection strength between the cloth funnel layers, making the manufacture of the cloth funnel layer simpler and faster. During use, only two long plates need to be cut according to the length requirement of the entire cloth funnel layer, and cuts 7 are arranged in sequence along the length direction on the two long plates. The plates inside the cuts 7 are folded inwards, and lower funnel plates 6 are arranged at intervals between the two long plates. The corresponding folded-in plates are connected by upper funnel plates 5 to form the entire cloth funnel layer.

[0042] An embodiment of the present invention further provides a device for realizing reverse contact between a gas phase and a solid phase, which includes a housing and a cloth funnel layer.

[0043] Specifically, the housing forms an accommodation space, the cloth funnel layer is the above-mentioned cloth funnel layer, the cloth funnel layer is arranged in the housing, and is connected to the side wall of the housing to divide the accommodation space into an upper space and a lower space. The lower space contains gas, and the solid material falls into the cloth funnel 1 from the upper space.

[0044] In other words, the cloth funnel layer includes two support plates, multiple pairs of upper funnel plates 5 and multiple pairs of lower funnel plates 6. The two support plates (i.e., the integral full-length plate 8) are arranged oppositely. Along the length direction of each support plate, a plurality of air inlet components are arranged at intervals. Each air inlet component includes: an air inlet hole (i.e., the cut 7) and a baffle (i.e., the inwardly bent part of the side panel at the cut 7). The air inlet hole is opposite to the baffle. The top end of the baffle is connected to the support plate with the air inlet hole, and the bottom end of the baffle has a gap with the support plate with the air inlet hole so that the baffle deflects relative to the support plate towards the space between the two support plates. The two upper funnel plates 5 are arranged oppositely and are located between the two support plates. The side end of the baffle is connected to the upper funnel plate 5. The two lower funnel plates 6 are arranged oppositely and are located below the two upper funnel plates 5 and between the two support plates. The caliber between the lower ends of the two upper funnel plates 5 is smaller than the caliber between the upper ends of the two lower funnel plates 6. The two upper funnel plates 5, the two lower funnel plates 6 and the two support plates are connected into a funnel shape, and the upper edges of two adjacent upper funnel plates 5 are connected.

[0045] Furthermore, the upper edges of the upper funnel plates 5 of adjacent cloth funnels 1 are abutted against each other, and the upper edges of multiple cloth funnels 1 are flush. By setting like this, the arrangement density of the cloth funnels 1 can be maximized, the falling amount of activated carbon per unit time can reach the maximum, and the contact between the gas and the activated carbon can be made more sufficient. Welding operations are not required between the mutually abutted upper funnel plates 5, reducing the workload of equipment manufacturing.

[0046] It should be noted that when the material falling into the cloth funnel 1 is activated carbon and the gas entering the cloth funnel 1 is flue gas, the cloth funnel 1 can be called a gas distribution device for desulfurization and denitrification or a gas distribution device for desulfurization or a gas distribution device for denitrification.

[0047] In summary, the device for realizing the reverse contact between the gas phase and the solid phase and its cloth funnel provided by the present invention adopt the form of the upper funnel 2 and the lower funnel 3, form an air inlet between the two funnel layers, so that the gas enters the inside of the cloth funnel 1 to be fully mixed with the material, and primary gas distribution is carried out at the air inlet; by adopting the secondary gas distributor 9 arranged in the upper funnel 2 of the cloth funnel 1, the upper funnel 2 is divided into multiple small funnels to form secondary gas distribution, making the contact with the solid more sufficient. The falling path of the material in the upper funnel 2 is dispersed, so that the gas is fully mixed with the material in the upper funnel 2, greatly increasing the contact opportunity between the gas and the material and improving the utilization rate of the material. The cloth funnel layer of the present invention uses two through-length plates 8 as the common sides of multiple cloth funnels 1 respectively, which not only saves materials, avoids cutting waste, but also increases the connection strength between the cloth funnels 1 in the cloth funnel layer, making the manufacture of the cloth funnel layer simpler and faster. The present invention adopts the method of partial bending to realize the production of the air inlet, greatly reducing the construction period.

[0048] The foregoing are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
