Description

Technical Field

[0001] The utility model relates to the technical field of scrubbers, in particular to a long-throat Venturi scrubber with a flow regulation structure. Background Art

[0002] The long-throat Venturi scrubber is a device for gas purification and particulate removal. By forming a low-pressure area between the contraction section and the diffusion section, the gas-liquid mixing is made more sufficient, thereby improving the removal efficiency of pollutants. Adjusting the flow rate plays an important role in the long-throat Venturi scrubber, which helps to optimize the equipment performance and enhance the purification effect.

[0003] A long-throat Venturi wet scrubber with adjustable flow rate recorded in the patent document with the publication number CN218901284U. The solution recorded therein adjusts the depth of the flow regulation component in the connection section by slidingly connecting the flow regulation component with the first connection part, and then adjusts the airway space in the connection section to make the flow rate of the dust-containing gas in a suitable state, which can improve the washing effect of the Venturi scrubber.

[0004] The above case has the problem that the dust-containing gas cannot be filtered. Since the dust-containing gas will carry impurities when entering the scrubber interior, if the impurities are not filtered, the impurities will deposit on various components of the scrubber, causing blockage of the air flow channel, reducing the gas flow rate and washing effect, and the hard particulate matter will also cause wear to the scrubber under the action of the high-speed gas flow.

An adjusting component for adjusting the gas flow is provided on one side of the inlet section 100. By pushing the limiting strip, it drives the concave plate 604 and the filter plate 603 to move, so that the filter plate 603 reaches inside the intake pipe 601, and filters the dust-containing gas entering from the intake pipe 601.

[0032] As Figure 1 and Figure 2 shown in the figure, the adjusting component includes a support frame 701, the support frame 701 is fixedly connected to one side of the inlet section 100, a motor 702 is provided on the other side of the support frame 701, a threaded rod is provided at the output end of the motor 702, a slider 703 is slidably connected inside the support frame 701, and the threaded rod is threadedly connected inside the slider 703. A clamping component for clamping the scrubbing pipe 500 is provided at the bottom of the slider 703. By starting the motor 702, it drives the threaded rod to rotate, and then drives the slider 703 to move.

[0033] As Figure 2 and Figure 4 shown in the figure, the clamping component includes a limiting plate 801, the limiting plate 801 is fixedly connected to both sides of the bottom of the slider 703, a clamping block 802 is slidably connected between the two limiting plates 801, a bidirectional lead screw 803 is rotatably connected between the two limiting plates 801, a turntable is provided at one end of the bidirectional lead screw 803, and the threads at both ends of the bidirectional lead screw 803 are threadedly connected inside the clamping block 802. Limiting rods are slidably connected to both ends inside the two clamping blocks 802, and both ends of the limiting rods are fixedly connected to the limiting plate 801. By rotating the turntable, it drives the bidirectional lead screw 803 to rotate, thereby driving the two clamping blocks 802 to approach or move away from each other.

[0034] As Figure 3As shown, a fixing component for limiting and fixing the limiting strip is provided on the concave plate 604. The fixing component includes a buckle 901 which is arranged at both ends of the top of the concave plate 604. Lock blocks 902 are arranged at both ends of the top of the limiting strip. By pulling the buckle 901 to reach the position of the lock block 902, the concave plate 604 and the limiting strip are limited and fixed.

[0035] As Figure 2 shown, a spray head is provided at one end of the washing pipe 500 inside the inlet section 100, and a plurality of spray holes are formed in the spray head so that the washing liquid can be evenly sprayed into the inlet section.

[0036] As Figure 1 shown, a regulating valve is provided on the deceleration section 200, and the gas flow rate entering the throat can be controlled through the regulating valve.

[0037] As Figure 2 and Figure 4 shown, the two clamping blocks 802 are adapted in shape and specification to prevent the washing pipe 500 from falling off during the clamping process.

[0038] Embodiment 2

[0039] As Figure 1 and Figure 3 shown, the difference from Embodiment 1 is that a handle is provided on the limiting strip to facilitate pulling the handle.

[0040] The above embodiments disclose a long-throat Venturi scrubber with a flow regulation structure. Among them, the dust-containing gas is discharged into the interior of the inlet section 100 through the air inlet pipe 601. Subsequently, the filter plate 603 filters it. Then, by rotating the turntable, it drives the bidirectional lead screw 803 to rotate, thereby driving the two clamping blocks 802 to approach each other, so as to clamp the scrubbing pipe 500. Subsequently, adjustments are made according to the discharge volume of the dust-containing gas. When the discharge volume of the dust-containing gas meets the usage standard, by starting the motor 702, it drives the threaded rod to rotate, and then drives the slider 703 to move, so as to drive the scrubbing pipe 500 to move outside the inlet section 100, making all the internal space be used as an air passage. When the discharge volume of the dust-containing gas decreases, the motor 702 is started again to drive the scrubbing pipe 500 to move inside the inlet section 100, making part of the space of the inlet section 100 be used as an air passage to increase the gas flow rate. It can also be manually adjusted according to the actual situation. By rotating the turntable, the two clamping blocks 802 can be separated from each other, so that the scrubbing pipe 500 can be manually operated to change the position of the scrubbing pipe 500 according to the judgment of the actual situation, ensuring that it can adapt to a large range of flow changes. The gas flow rate into the throat can also be controlled by adjusting the valve. When the dust-containing gas enters the Venturi scrubber, due to the gradually decreasing cross-sectional area, the gas flow rate gradually increases and reaches the maximum in the throat section 300. At this time, the interior of the inlet section 100 is sprayed through several spray holes on the scrubbing pipe 500, spraying the liquid into the high-speed airflow to form a large number of fine droplets. These droplets collide and coagulate with the particulate matter and pollutants in the airflow, thereby realizing the capture of pollutants. When the gas enters the diffuser section 400, the flow rate gradually decreases, the pressure rises, and gas-liquid separation occurs. The clean gas finally discharges from the interior of the diffuser section 400.

[0041] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
