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 flow inlet of the throat mechanism, and its relative position with the throat inlet connected to the throat mechanism is adjustable, so as to adjust the cross-sectional area of ​​the gas entering the throat mechanism; the synthetic gas enters from the air inlet, and the washing water enters from the nozzle. The washing water is impacted, crushed, and atomized by the high-speed gas. Afterwards, the synthetic gas and the atomized washing water enter the throat mechanism through the gap between the adjusting cone head and the throat mechanism. Inside the throat mechanism, the gas flow rate increases rapidly and flows out.

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0029] Reference Figure 1-11 As shown, the present invention provides an adjustable load long-tube venturi wet scrubber, comprising 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 through, and further comprising: a cross-section adjustment mechanism: which is arranged in the second tank body 1.1 and moves in the throat portion of the second tank body 1.1;

[0030] When the unstable gas enters the throat portion of the second tank body 1.1, the gas pressure pushes the cross-section adjustment mechanism to move in the throat portion of the second tank body 1.1, thereby adjusting the pressure at the throat portion.

[0031] 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 through-connected, the second tank body 1.1 is provided with a throat portion, the second tank body 1.1 includes an air inlet, and a spray pipe is fixedly connected to the second tank body 1.1 near the upper portion, a plurality of spray holes are linearly and equidistantly provided 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 provided in the first tank body 1, a centrifuge is fixedly connected to the upper portion of the first tank body 1, and an exhaust port is provided near the top of the first tank body 1 to discharge clean gas.

[0032] In the prior art, a regulating mechanism is provided in the throat of the second tank 1.1 of the Venturi scrubber for regulating the cross-sectional area of ​​gas entering the throat mechanism, but the regulation is performed manually or electrically. The regulating mechanism generally only needs to be adjusted once when a constant pressure of gas flows into the air inlet. However, if an unstable airflow is introduced into the second tank 1.1, the pressure of the throat will fluctuate. In order to ensure that the air pressure in the throat is within a certain range, it is necessary to adjust the cross-sectional area in the throat according to the air pressure in the throat. If the regulation is performed according to the air pressure in the process, a flow detection device and an electric regulating device need to be added to cooperate in order to perform the regulation, and the regulation is frequently performed according to the actual situation. In this example, a cross-sectional regulating mechanism is provided in the throat, and the cross-sectional regulating mechanism is adjusted according to the size of the gas pressure in the second tank 1.1, so that the cross-sectional regulating mechanism moves in the axial direction or radial direction of the throat to adjust the cross-sectional area of ​​the throat, so as to maintain the load at the throat in the second tank 1.1 within a certain range.

[0033] Cross-section adjustment mechanism: It is arranged at the throat portion inside the second tank body 1.1. The cross-section adjustment mechanism moves in the axial direction or radial direction of the throat portion to adjust the cross-section of the throat portion. Since the cross-section adjustment mechanism is adjusted according to the size of the air pressure, it has a certain elastic compensation ability. In the prior art, springs, elastic rubber and other structures can be used.

[0034] During use, when unstable gas flows into the second tank body 1.1, the gas flow rate will fluctuate. If the gas pressure is low, the cross-section adjusting mechanism is located in the middle of the throat, which is the narrowest position. At this time, the cross-section is the largest. When the gas flow rate gradually increases, the gas pressure will push the cross-section adjusting mechanism to move at the throat position in the second tank body 1.1, so that it gradually moves from the narrowest position of the throat to the widest position of the throat according to the size of the gas pressure. Then, the cross-section adjusting mechanism will adjust its cross-section at the throat position according to the size of the gas pressure, so that the load at the throat is kept within a certain range.

[0035] The present invention provides an adjustable load long-tube Venturi wet scrubber. When the inflowing gas with unstable air pressure in the second tank body 1.1 reaches a preset range, the air pressure pushes the cross-section adjustment mechanism at the throat portion to move in the radial or axial direction of the throat portion, thereby adjusting the air pressure in the throat portion so that the load of the throat portion is maintained within a certain range.

[0036] Reference Figure 3-11As shown, in another embodiment provided by the present invention, the cross-section adjustment mechanism includes a first adjustment component and a second adjustment component, the first adjustment component is used for adjusting the axial cross-sectional area of ​​the second tank body 1.1, and the second adjustment component is used for adjusting the radial cross-sectional area of ​​the second tank body 1.1.

[0037] The cross-sectional adjustment mechanism in the throat portion includes a first adjustment component and a second adjustment component. The first adjustment component is used for adjusting the cross-sectional area of ​​the second tank body 1.1 in the axial direction, and the second adjustment component is used for adjusting the cross-sectional area of ​​the second tank body 1.1 in the radial direction.

[0038] The second adjustment assembly comprises a fixing tube 1.10 fixedly connected to the second tank body 1.1 and a connecting seat 1.11 axially slidably connected to the fixing tube 1.10. The fixing tube 1.10 and the connecting seat 1.11 are connected via a spring 1.101.

[0039] Two first section regulators 1.14 are rotatably connected to the connecting seat 1.11, and a second transmission unit is arranged between each first section regulator 1.14, so that the two first section regulators 1.14 are driven to rotate during the downward movement of the connecting seat 1.11 to squeeze and crush the large particles.

[0040] The second transmission unit includes a gear 1.12 coaxially fixedly connected to each first section adjuster 1.14 and a first rack 1.13 fixedly connected to the second tank body 1.1, the first rack 1.13 is meshed with one of the gears 1.12, a second rack 1.15 is meshed between the two gears 1.12, and the second rack 1.15 is slidably connected in the fixed tube 1.10.

[0041] The second adjustment assembly comprises two second cross-section adjusters 1.16 which are slidably connected in the radial direction in the second tank body 1.1, and each second cross-section adjuster 1.16 is located at two opposite sides of the second tank body 1.1.

[0042] The second transmission unit drives each second cross-section adjuster 1.16 to move when the moving seat moves downward.

[0043] The second transmission unit comprises connection blocks 1.111 fixedly connected to both sides of the connection seat 1.11, each connection block 1.111 is respectively connected with a wedge-shaped groove 1.1110, and each second cross-section adjuster 1.16 is respectively provided with a transmission pin matched with the wedge-shaped groove 1.1110.

[0044] Two support seats 1.100 are fixedly connected around the inner wall of the second tank body 1.1, and each second cross-section adjuster 1.16 is installed in the second tank body 1.1 through each support seat 1.100.

[0045] A second limiting groove 1.150 is provided on the second rack 1.15, and a clamping block 1.103 adapted thereto is fixedly connected to the peripheral side of the fixed tube 1.10 at a position corresponding to the second limiting groove 1.150.

[0046] Specifically, Figure 10-11 As shown, a fixing tube 1.10 is fixedly connected inside the second tank body 1.1, a spring 1.101 is fixedly connected inside the fixing tube 1.10, and two first limiting grooves 1.102 are arranged around the inner wall of the fixing tube 1.10, a cylinder adapted to the fixing tube 1.10 is fixedly connected to the connecting seat 1.11, and a limiting pin 1.110 adapted to the fixing tube 1.10 is fixedly connected at a position corresponding to each first limiting groove 1.102 on the circumferential side of the cylinder, and the end of the cylinder is fixedly connected to one end of the spring 1.101, and two first section adjusters 1.14 are rotatably connected to the connecting seat 1.11, and a gear 1.12 is coaxially fixedly connected to the two first section adjusters 1.14, and a second gear 1.12 is meshed between the two gears 1.12, and a second limiting groove 1.150 is arranged through the end surface of the second gear 1.12, and a position corresponding to the second limiting groove 1.150 on the circumferential side of the fixing tube 1.10 is fixedly connected to the fixing tube 1.10. A card block 1.103 adapted to it is fixedly connected, and a first gear 1.12 is meshed on the circumferential side of one of the gears 1.12. The first gear 1.12 is fixedly connected to the inside of the second tank body 1.1. Inside the second tank body 1.1, two support seats 1.100 are fixedly connected in the radial direction near the widest part of the throat portion, and a waist-shaped groove is provided through the end face of each support seat 1.100. A connecting shaft adapted to the waist-shaped groove is fixedly connected in the axial direction of the second section regulator 1.16. A connecting block 1.111 is fixedly connected on the opposite sides of the support seat 1.100, and each connecting block 1.111 is provided with a wedge-shaped groove 1.1110.

[0047] During use, when unstable gas flows into the second tank body 1.1, the gas flow rate will fluctuate. If the gas pressure is small (less than a predetermined value, which is set by technicians in the field according to the on-site installation and production requirements), the two first section regulators 1.14 on the connecting seat 1.11 are located in the middle of the throat, that is, the narrowest position. At this time, the cross-section is the largest, that is, the load at the throat is kept within a preset range. When the gas flow rate gradually increases, the gas pressure at the throat increases, which will cause the load on each first section regulator 1.14 in the throat to exceed the preset value. At this time, the gas pressure will push the first section regulator 1.14 to move downward, so that the gear 1.12 on the first section regulator 1.14 meshes with the first gear, driving it to rotate, so that the first section regulator 1.14 meshes with the second rack 1.15, driving the second rack 1.15 to move downward, and then the second rack 1.15 drives another first section regulator 1.14. Rotate, so that the two first section regulators 1.14 rotate in opposite directions, and the distance between the centers of the two first section regulators 1.14 can be set according to the technology in the field as needed, so that the circumferential sides of the two first section regulators 1.14 can abut against each other or the gap is small, and large particles in the gas can be crushed (the large particles in this embodiment are some particles with smaller hardness, such as mud balls, etc.). In the process of the connecting seat 1.11 moving downward, each second section regulator 1.16 moves in the waist groove and the wedge groove 1.1110 respectively, so that the second section regulator 1.16 moves in the radial direction of the second tank body 1.1, and the axial section in the second tank body 1.1 is adjusted, so that the section adjustment mechanism will adjust its section at the throat position according to the size of the air pressure. When the air pressure becomes smaller, the first section regulator 1.14 and the second section regulator 1.16 are reset under the action of the spring 1.101, so that the load at the throat is kept within a certain range.
