The original application date is July 31, 2024. The entire content of the original application is incorporated herein by reference. Technical Field

[0002] The present invention relates to the technical field of Venturi tubes, and specifically relates to an adjustable load long tube Venturi wet scrubber. Background Art

[0003] In the invention patent application with the publication (announcement) number: CN094765A, the publication (announcement) date: 00-04-03, and the title: An adjustable load long throat Venturi scrubber, it includes a scrubber comprising an elbow, a nozzle, a throat mechanism, and an adjusting cone head. One end of the elbow is an air inlet, and the other end is connected to the throat mechanism. The nozzle is installed on the side wall of the elbow. The adjusting cone head is located at the air inlet of the throat mechanism, and its relative position with respect to the inlet of the throat mechanism connected to the throat mechanism is adjustable, thereby adjusting the cross-sectional area of the gas entering the throat mechanism. The syngas enters from the air inlet, and the washing water enters from the nozzle. The washing water is impacted, broken, and atomized by the high-speed gas. After that, the syngas and the atomized washing water enter the throat mechanism through the gap between the adjusting cone head and the throat mechanism connected. Inside the throat mechanism, the gas flow rate increases rapidly and flows out. The present invention increases the online adjustable ability of the long throat Venturi scrubber and optimizes the spraying structure of the Venturi scrubber nozzle, improving the washing effect of the Venturi scrubber.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0023] Referring to Figures 1-11 As shown, the present invention provides an adjustable-load long-tube Venturi wet scrubber, which includes a first tank body 1 and a second tank body 1.1. The first tank body 1 and the second tank body 1.1 are connected in a through manner, and further includes: a cross-section adjusting mechanism: which is arranged in the second tank body 1.1 and moves in the throat part of the second tank body 1.1; When unstable gas enters the throat part of the second tank body 1.1, the air pressure pushes the cross-section adjusting mechanism to move in the throat part of the second tank body 1.1, thereby realizing the adjustment of the pressure at the position of the throat part.

[0024] Specifically, as shown in the figure, the scrubber includes a first tank body 1 and a second tank body 1.1. The first tank body 1 and the second tank body 1.1 are connected in a through manner. The second tank body 1.1 is provided with a throat part. The second tank body 1.1 includes an air inlet, and a spray pipe is fixedly connected at a position near the upper part inside the second tank body 1.1. A plurality of spray holes are linearly and equidistantly arranged in the axial direction of the spray pipe, and a valve is installed on the spray pipe. A droplet aggregation structure and a filtering structure are arranged inside the first tank body 1. A centrifuge is fixedly connected to the upper part of the first tank body 1. An exhaust port is opened at a position near the top of the first tank body 1, and then the clean gas is discharged.

[0025] In the prior art, an adjusting mechanism is provided in the throat part of the Venturi scrubber, that is, the second tank body 1.1, to adjust the cross-sectional area of the mechanism for the gas to enter the throat part. However, the adjustment is carried out manually or electrically. The adjusting mechanism generally only needs to be adjusted once when the gas with a constant pressure flows into the air inlet. However, if unstable air flow is introduced into the second tank body 1.1, the pressure in the throat part will fluctuate up and down. In order to ensure that the air pressure in the throat part is within a certain range, it is necessary to adjust the cross-sectional area in the throat part according to the air pressure in the throat part. And in this process, if it is necessary to adjust according to the air pressure, it is necessary to add a flow detection device and an electric adjustment device to cooperate for adjustment, and it is adjusted frequently according to the actual situation. In this example, by providing a cross-section adjusting mechanism in the throat part, it will be adjusted according to the magnitude of the gas pressure introduced into the second tank body 1.1, so that the cross-section adjusting mechanism moves axially or radially in the throat part to adjust the cross-sectional area of the throat part, and realize that the load at the throat part in the second tank body 1.1 is maintained within a certain range.

[0026] Cross-section adjusting mechanism: It is arranged at the position of the throat part inside the second tank body 1.1. The cross-section adjusting mechanism moves axially or radially in the throat part to adjust the cross-section of the throat part. And since the cross-section adjusting mechanism is adjusted according to the magnitude of the air pressure, it has a certain elastic compensation ability. Structures such as springs and elastic rubbers can be used in the prior art.

[0027] During the use process, when unstable gas flows into the second tank body 1.1, the flow rate of the gas will be large or small at this time. If the air pressure of the gas is small, at this time the cross-section adjusting mechanism is located at the middle, i.e., the narrowest position, of the throat part, and the cross-section is the largest at this time. When the flow rate of the gas gradually increases, it will cause the air pressure to push the cross-section adjusting mechanism to move at the position of the throat part inside the second tank body 1.1, so that it gradually moves from the narrowest position of the throat part to the widest position of the throat part according to the magnitude of the air pressure. Furthermore, the cross-section adjusting mechanism will adjust its cross-section at the position of the throat part according to the magnitude of the air pressure, so that the load at the throat part is maintained within a certain range.

[0028] For an adjustable-load long-tube Venturi wet scrubber provided by the present invention, when unstable gas flows into the second tank body 1.1, when the air pressure reaches the preset range, at this time the air pressure is used to push the cross-section adjusting mechanism at the position of the throat part to move radially or axially in the throat part, so as to adjust the air pressure inside the throat part and keep the load of the throat part within a certain range.

[0029] Refer to Figures 3-11 As shown, in another embodiment provided by the present invention, the cross-section adjusting mechanism includes a first adjusting component and a second adjusting component. The first adjusting component is used for the cross-sectional area in the axial direction of the second tank body 1.1, and the second adjusting component is used for adjusting the cross-sectional area in the radial direction of the second tank body 1.1.

[0030] Among them, the cross-section adjusting mechanism inside the throat part includes a first adjusting component and a second adjusting component. The first adjusting component is used for the cross-sectional area in the axial direction of the second tank body 1.1, and the second adjusting component is used for adjusting the cross-sectional area in the radial direction of the second tank body 1.1.

[0031] The second adjusting component includes a fixed pipe 1.10 fixedly connected inside the second tank body 1.1 and a connecting seat 1.11 slidably connected axially to the fixed pipe 1.10. A spring 1.101 is used to connect the fixed pipe 1.10 and the connecting seat 1.11.

[0032] Two first cross-section regulators 1.14 are rotatably connected to the connecting seat 1.11, and a second transmission unit is arranged between the first cross-section regulators 1.14. Thus, when the connecting seat 1.11 moves downward, the two first cross-section regulators 1.14 are driven to rotate to extrude and crush large particles.

[0033] The second transmission unit includes gears 1.12 coaxially and fixedly connected to the first cross-section regulators 1.14 respectively and a first rack 1.13 fixedly connected to the second tank body 1.1. The first rack 1.13 meshes with one of the gears 1.12, and a second rack 1.15 meshes between the two gears 1.12. The second rack 1.15 is slidably connected in the fixed pipe 1.10.

[0034] The second adjustment assembly includes two second cross-section regulators 1.16 slidably connected in the radial direction in the second tank body 1.1, and the second cross-section regulators 1.16 are respectively located on opposite sides in the second tank body 1.1.

[0035] The second transmission unit drives the second cross-section regulators 1.16 to move when the moving seat moves downward.

[0036] The second transmission unit includes connection blocks 1.111 fixedly connected to both sides of the connecting seat 1.11. A wedge-shaped groove 1.1110 is respectively and penetratingly connected to each connection block 1.111, and a transmission pin adapted to the wedge-shaped groove 1.1110 is respectively arranged on each second cross-section regulator 1.16.

[0037] Two support seats 1.100 are fixedly connected around the inner wall circumference of the second tank body 1.1, and each second cross-section regulator 1.16 is installed in the second tank body 1.1 through each support seat 1.100.

[0038] A second limiting groove 1.150 is formed on the second rack 1.15, and a block 1.103 adapted to the second limiting groove 1.150 is fixedly connected to the circumference of the fixed pipe 1.10 at a position corresponding to the second limiting groove 1.150.

[0039] Specifically, such as Figures 10-11As shown, a fixed pipe 1.10 is fixedly connected inside the second tank body 1.1. A spring 1.101 is fixedly connected inside the fixed pipe 1.10. Two first limiting grooves 1.102 are circumferentially formed on the inner wall of the fixed pipe 1.10. A cylinder adapted to the fixed pipe 1.10 is fixedly connected to the connecting seat 1.11. A limiting pin 1.110 adapted to each first limiting groove 1.102 is fixedly connected to the circumferential side of the cylinder at positions corresponding to the first limiting grooves 1.102. The end of the cylinder is fixedly connected to one end of the spring 1.101. Two first cross-section regulators 1.14 are respectively rotatably connected to the connecting seat 1.11. A gear 1.12 is coaxially fixedly connected to each of the two first cross-section regulators 1.14. A second gear 1.12 is engaged between the two gears 1.12. A second limiting groove 1.150 is formed through the end face of the second gear 1.12. A block 1.103 adapted to the second limiting groove 1.150 is fixedly connected to the circumferential side of the fixed pipe 1.10 at a position corresponding to the second limiting groove 1.150. A first gear 1.12 is engaged with the circumferential side of one of the gears 1.12. The first gear 1.12 is fixedly connected inside the second tank body 1.1. Inside the second tank body 1.1, two support seats 1.100 are circumferentially and fixedly connected in the radial direction at a position near the widest part of the throat portion. A waist-shaped groove is formed through the end face of each support seat 1.100. A connecting shaft adapted to the waist-shaped groove is fixedly connected to the axial direction of the second cross-section regulator 1.16. A connecting block 1.111 is fixedly connected to each of the opposite sides of the support seat 1.100. A wedge-shaped groove 1.1110 is formed in each connecting block 1.111. A connecting pin 1.160 adapted to the wedge-shaped groove 1.1110 is fixedly connected to the end face of each second cross-section regulator 1.16. Each connecting pin 1.160 is respectively arranged in the wedge-shaped groove 1.1110 corresponding to it.

[0040] During use, when unstable gas flows into the second tank 1.1, the gas flow rate will be large or small. If the gas pressure is small (less than a predetermined value, which is set by those skilled in the art according to the on-site installation and manufacturing requirements), at this time, the two first cross-section regulators 1.14 on the connecting seat 1.11 are located in the middle of the throat section, that is, the narrowest position. At this time, the cross-section is the largest, that is, the load at the throat section is maintained within the preset range. When the gas flow rate gradually increases, the gas pressure at the throat section increases, which will cause the load on each first cross-section regulator 1.14 in the throat section to exceed the preset value. At this time, the gas pressure will push the first cross-section regulator 1.14 downward, causing the gear 1.12 on the first cross-section regulator 1.14 to mesh with the first one, driving it to rotate, causing the first cross-section regulator 1.14 to mesh with the second rack 1.15, driving the second rack 1.15 downward, and further causing the second rack 1.15 to drive the other first cross-section regulator 1.14 to rotate. As a result, the two first cross-section regulators 1.14 rotate in opposite directions, and the distance between the centers of the two first cross-section regulators 1.14 can be set by those skilled in the art according to needs, so that the circumferences of the two first cross-section regulators 1.14 can abut against each other or have a small gap, and can break large particles in the gas. (In this embodiment, the large particles are some particles with relatively low hardness, such as mud balls, etc.). During the downward movement of the connecting seat 1.11, the second cross-section regulators 1.16 move in the waist-shaped groove and the wedge-shaped groove 1.1110 respectively, so that the second cross-section regulators 1.16 move in the radial direction of the second tank 1.1, adjusting the axial cross-section in the second tank 1.1. Thus, the cross-section adjusting mechanism will adjust its cross-section at the throat section according to the gas pressure. When the gas pressure becomes small, at this time, under the action of the spring 1.101, the first cross-section regulator 1.14 and the second cross-section regulator 1.16 are reset, so that the load at the throat section is maintained within a certain range.

[0041] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
