[0018] The following provides a detailed description of the specific embodiments of this utility model. It should be understood that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of this utility model.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] The first aspect of this utility model provides a fluid mixing device, such as... Figure 1 As shown, the fluid mixing device includes: Casing 1; A wedge-shaped block 8 is horizontally disposed inside the housing 1, and divides the interior of the housing 1 into a first fluid channel 10 and a second fluid channel 11. The first slider 2 is disposed on the inner top surface of the housing 1, and is disposed parallel to the end face of the wedge block 8 opposite to the first slider 2. The second slider 5 is disposed on the inner bottom surface of the housing 1, and is disposed parallel to the end face of the wedge block 8 opposite to the second slider 5. The first drive motor 3 is fixedly installed on the inner top surface of the housing 1. Its rotating end is connected to the first lead screw 4. One end of the first lead screw 4 passes horizontally through the interior of the first slider 2 and is used to drive the first slider 2 to slide horizontally along the inner top surface of the housing 1. The second drive motor 7 is fixedly installed on the inner bottom surface of the housing 1. Its rotating end is connected to the second lead screw 6. One end of the second lead screw 6 passes horizontally through the interior of the second slider 5, and is used to drive the second slider 5 to slide horizontally along the inner bottom surface of the housing 1.

[0022] Specifically, based on the lead screw thread, for example, when the drive motor rotates forward / reverse, the lead screw drives the slider to slide horizontally from left to right, and when the drive motor rotates in reverse / forward, the lead screw drives the slider to slide horizontally from right to left. In this way, by adjusting the cross-sectional area of ​​the fluid outlet, the fluid flow rate can be adjusted to achieve precise mixing of the two fluids.

[0023] According to the above technical solution, based on this fluid mixing device, in practical applications, the fluid flow rate can be adjusted by adjusting the size of the fluid outlet cross-sectional area, so as to achieve precise mixing of gas-liquid, gas-gas, and liquid-liquid in a set ratio, thereby meeting the application needs of various application scenarios.

[0024] Specifically, the fluid mixing device adopts a modular design and can be configured into N types of gas and N types of liquid mixing modules according to different application scenarios.

[0025] In the fluid mixing device described in this utility model, preferably, as follows: Figure 1 As shown, the cross-section of the wedge block 8 is arrow-shaped, and the included angle formed by the arrowhead being symmetrically arranged with respect to the shaft axis is α, thereby dividing the interior of the housing 1 into equal parts, making the first fluid channel 10 and the second fluid channel 11 the same size, and better controlling the fluid flow.

[0026] More preferably, the cross-sections of the first slider 2 and the second slider 5 are both right angles, and the hypotenuse of the first slider 2, which has a right angle cross-section, is parallel to one hypotenuse of the arrow of the wedge block 8, and the hypotenuse of the second slider 5, which has a right angle cross-section, is parallel to the other hypotenuse of the arrow of the wedge block 8. Thus, in practical applications, the sliders can be driven to slide under the action of the drive motor, and the fluid flow rate can be adjusted by adjusting the size of the fluid outlet cross-sectional area, so as to achieve precise mixing of different fluids in a set ratio.

[0027] In a further preferred embodiment, the angle between the hypotenuse of the first slider 2 (with a right-angled cross-section) and its long right-angled side, and the angle between the hypotenuse of the second slider 5 (with a right-angled cross-section) and its long right-angled side, are both α. Specifically, the angle α is preferably 3-8°, further preferably 5-7°, and most preferably 6°. The sliding distance control accuracy is 1 / tanα times the distance control accuracy. Taking α=6° as an example, the control accuracy can be improved tenfold.

[0028] In another preferred embodiment, such as Figure 1As shown, the first slider 2 and the second slider 5 are the same size. Therefore, based on the symmetrical arrangement of the upper and lower fluid channels, the mixing ratio of the two fluids can be better adjusted in practical applications, thereby improving the ease of mixing operation and mixing accuracy.

[0029] In the fluid mixing device described in this utility model, preferably, as follows: Figure 1 As shown, a lead screw support plate 9 is provided on both the inner top surface and the inner bottom surface of the housing 1. The lead screw support plate 9 has a threaded hole for installing the lead screw, thereby limiting and supporting the lead screw, and thus improving the stability of the slider's horizontal sliding.

[0030] In the fluid mixing device described in this utility model, preferably, a controller is also provided outside the housing 1. The controller is electrically connected to the first drive motor 3 and the second drive motor 7 and is used to control the rotation speed and direction of the first lead screw 4 and the second lead screw 6, so as to better control the sliding of the slider and more accurately adjust the fluid flow rate by adjusting the size of the fluid outlet cross-sectional area, so as to achieve precise mixing of different fluids in a set ratio.

[0031] Further preferably, flow meters are provided at the outlets of both the first fluid channel 10 and the second fluid channel 11. The controller is used to dynamically control the rotational speed and direction of the first lead screw 4 and the second lead screw 6 based on the fluid flow rate values ​​measured by the flow meters. This allows for further feedback adjustment to improve the accuracy of mixing different fluids in a set ratio when the fluid flow rates at the two fluid outlets deviate from the set flow rates. Specifically, the flow meters can be set according to actual needs. When setting flow meters, appropriate types of flow meters can be set according to application requirements. For example, when mainly used for gas-liquid mixing, gas flow meters and liquid flow meters can be set at the two fluid outlets respectively; when mainly used for gas-gas mixing, gas flow meters can be set at the two fluid outlets; and when mainly used for liquid-liquid mixing, liquid flow meters can be set at the two fluid outlets.

[0032] The second aspect of this invention provides the application of the fluid mixing device in a wet scrubber. The fluid mixing device is used to mix the reagent and water in a predetermined ratio and then introduce the mixture into the liquid inlet of the wet scrubber, thereby improving the dust removal efficiency of the wet scrubber. Specifically, wet scrubbers typically require different reagents to remove different components of flue gas, and the mixing ratio of different reagents with water usually varies. Using the fluid mixing device described in this invention, the fluid flow rate can be flexibly adjusted by changing the cross-sectional area of ​​the fluid outlet according to actual needs, thereby achieving precise mixing of different fluids in a predetermined ratio.

[0033] The present invention will be described in detail below through embodiments, but the scope of protection of the present invention is not limited thereto.

[0034] Example 1 Adopting such Figure 1 The fluid mixing device shown mixes two different fluids. Specifically, the fluid mixing device includes: Casing 1; A wedge-shaped block 8 is horizontally disposed inside the housing 1, and divides the interior of the housing 1 into a first fluid channel 10 and a second fluid channel 11. The first slider 2 is disposed on the inner top surface of the housing 1, and is disposed parallel to the end face of the wedge block 8 opposite to the first slider 2. The second slider 5 is disposed on the inner bottom surface of the housing 1, and is disposed parallel to the opposite end face of the wedge block 8. The first drive motor 3 is fixedly installed on the inner top surface of the housing 1. Its rotating end is connected to the first lead screw 4. One end of the first lead screw 4 passes horizontally through the interior of the first slider 2 and is used to drive the first slider 2 to slide horizontally along the inner top surface of the housing 1. The second drive motor 7 is fixedly installed on the inner bottom surface of the housing 1. Its rotating end is connected to the second lead screw 6. One end of the second lead screw 6 passes horizontally through the interior of the second slider 5, and is used to drive the second slider 5 to slide horizontally along the inner bottom surface of the housing 1. Specifically, the wedge block 8 has an arrow-shaped cross-section, and the included angle formed by the arrowhead symmetrically arranged with respect to the axis of the arrow shaft is α; the cross-sections of the first slider 2 and the second slider 5 are both right-angled, and the hypotenuse of the first slider 2 with a right-angled cross-section is parallel to one hypotenuse of the arrowhead of the wedge block 8, and the hypotenuse of the second slider 5 with a right-angled cross-section is parallel to the other hypotenuse of the arrowhead of the wedge block 8; the included angle between the hypotenuse of the first slider 2 with a right-angled cross-section and its long right-angled side, and the included angle between the hypotenuse of the second slider 5 with a right-angled cross-section and its long right-angled side are both α; the included angle α is 6°; the first slider 2 and the second slider 5 are the same size; a screw support plate 9 is provided on the inner top surface and the inner bottom surface of the housing 1, and the screw support plate 9 has a threaded hole for installing the screw.

[0035] In practical applications, such as Figure 1 As shown, when fluid A and fluid B need to be mixed in a 1:2 ratio, the first drive motor 3 is first controlled to drive the first slider 2 to slide, and the second drive motor 7 drives the second slider 5 to slide, so that the ratio of the cross-sectional area of ​​the fluid outlet of the first fluid channel 10 to the cross-sectional area of ​​the fluid outlet of the second fluid channel 11 is 1:2. Then, fluid A is introduced into the inlet of the first fluid channel 10 and fluid B is introduced into the inlet of the second fluid channel 11. Finally, fluid A and fluid B are precisely mixed at a flow rate ratio of 1:2 after being output from their respective outlets.

[0036] Testing has shown that the fluid mixing device described in this invention can achieve precise mixing of any two fluids in a set ratio in practical applications, thereby meeting the application needs of various application scenarios.

[0037] Example 2 Referring to Embodiment 1, the difference is that a controller is also included outside the housing 1. The controller is electrically connected to the first drive motor 3 and the second drive motor 7 and is used to control the rotation speed and direction of the first lead screw 4 and the second lead screw 6. Flow meters are provided at the outlet ends of the first fluid channel 10 and the second fluid channel 11. The controller is used to dynamically control the rotation speed and direction of the first lead screw 4 and the second lead screw 6 according to the fluid flow rate value measured by the flow meters.

[0038] Testing has shown that, compared to the solution in Example 1, the fluid mixing device described in this utility model can further improve the accuracy of mixing any two fluids in a set ratio.

The first slider can slide horizontally along the inner top surface of the housing under the drive of the first drive motor, and the second slider can slide horizontally along the inner bottom surface of the housing under the drive of the second drive motor. In practical applications, the fluid flow rate can be adjusted by adjusting the size of the fluid outlet cross-sectional area to achieve precise mixing of gas-liquid, gas-gas, and liquid-liquid in a set ratio, thereby meeting the application needs of various application scenarios.
