Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cell diffusion equipment, in particular to a liquid mixing device and a tail discharge processing system. Background Art

[0002] During the boron expansion tail gas treatment process, one tail gas treatment method is to preliminarily cool the tail gas before passing it into water, and the tail gas hydrolyzes boron oxide to achieve the boron oxide remaining in the liquid bottle. In the prior art, the tail gas is directly passed into the water bottle, so that the gas is directly passed into the water bottle, and the bubbles rise from the bottom of the water to the water surface. However, this method has the problem that the bubbles formed by the gas are relatively large, and the part of the bubble surface area in contact with water is partially dissolved in the water, but the gas inside the bubble formed is not in contact with water, and the contact between the gas and water is not sufficient, and the boron oxide in the tail gas is not completely and fully dissolved in the water. The dissolution of boron oxide is not thorough enough, and the white boron oxide powder in the tail gas accumulates in the pipeline. As a result, the pump speed is too high, the diaphragm of the pump is damaged, the equipment is affected, the process pressure is unstable, the film formation uniformity is poor, and the product yield is low. Utility Model Content

[0003] Based on this, it is necessary to provide a liquid mixing device and tail gas treatment system to address the technical problem that the contact between gas and water in the boron expansion tail gas treatment process in the existing technology is not sufficient, resulting in the boron oxide in the tail gas not being fully dissolved in water.

[0040] See Figures 2 to 4 , an embodiment of the present invention provides a liquid mixing device 300, which includes a liquid mixing bottle 310, a bottle cap 320, an air inlet pipe 33, an air outlet pipe 340 and a baffle 350. The liquid mixing bottle 310 is configured with a liquid mixing cavity with an open end; the bottle cap 320 is arranged on the mouth of the liquid mixing bottle 310; the air inlet pipe 33 passes through the bottle cap 320 and is inserted into the bottom of the liquid mixing cavity; the air outlet pipe 340 passes through the bottle cap 320 and extends into the liquid mixing cavity, for discharging the gas in the liquid mixing bottle 310; the baffle 350 is rotatably connected to the air inlet pipe 33; wherein, the exhaust gas is passed from the air inlet pipe 33 to the bottom of the liquid mixing cavity, and the baffle 350 rotates around the air inlet pipe 33 under the action of the rising exhaust gas.

[0041] The present invention provides a liquid mixing device 300. A liquid mixing bottle 310 is provided with a liquid mixing cavity for mixing boron oxide in exhaust gas with water. A bottle cap 320 is provided at the mouth of the liquid mixing bottle 310 to seal the liquid mixing cavity of the liquid mixing bottle 310, thereby preventing the exhaust gas entering the liquid mixing bottle 310 from escaping through the mouth of the liquid mixing bottle 310. An air inlet pipe 33 is inserted through the bottle cap 320 to the bottom of the liquid mixing cavity, allowing the exhaust gas containing boron oxide powder to enter the bottom of the liquid mixing cavity through the air inlet pipe 33, thereby extending the mixing path of the exhaust gas and water, allowing the boron oxide to mix more fully with the water. An air outlet pipe 340 is inserted through the bottle cap 320 and into the liquid mixing cavity, so that the gas in the liquid mixing bottle 310 can be discharged through the air outlet pipe 340. By arranging a baffle 350 on the air inlet pipe 33 and rotatably connecting the baffle 350 to the air inlet pipe 33, after the exhaust gas enters the bottom of the mixed liquid chamber from the air inlet pipe 33, the baffle 350 rotates around the air inlet pipe 33 under the action of the rising exhaust gas. The rotation of the baffle 350 changes the rising route of the exhaust gas in the water from a straight line to a curve, thereby extending the path of the gas in the water, which is beneficial for the boron oxide in the exhaust gas to be more fully mixed with water; in addition, the rotation of the baffle 350 can make the volume of the bubbles formed in the water as small as possible, thereby increasing the contact area between the bubbles and the water, and thus making the boron oxide and the water mix more fully; and, the rotation of the baffle 350 disturbs the water flow in the mixed liquid chamber, so that the bubbles and the water are mixed evenly. Through the above structure, the boron oxide in the exhaust gas can be fully dissolved in water, thereby achieving better exhaust gas treatment effects, and further reducing the solid powder particles in the exhaust gas passing through the vacuum pump 500, thereby reducing the maintenance of the pump 500 and back-end management, and reducing maintenance time and costs.

[0042] It should be noted that in this embodiment, the baffle 350 rotates relative to the air inlet pipe 33 by virtue of the buoyancy of the gas. A sealing ring is provided between the air inlet pipe 33 and the cover plate to seal the gap therebetween. Similarly, a sealing ring is provided between the air outlet pipe 340 and the bottle cap 320 to seal the gap therebetween.

[0043] like Figure 3 and Figure 4 As shown, in one embodiment, the baffle 350 includes a rotating shaft 351 and blades 352. The rotating shaft 351 is configured with an axially extending mounting hole. The rotating shaft 351 is sleeved on the air inlet pipe 33 through the mounting hole. The rotating shaft 351 is rotatably connected to the air inlet pipe 33 via a bearing. The blades 352 are fixedly connected to the outer circumference of the rotating shaft 351. Specifically, the blades 352 are configured as a spiral structure.

[0044] A mounting hole extending axially through the rotating shaft 351 is provided to facilitate connection of the rotating shaft 351 to the air inlet pipe 33. The rotating shaft 351 is rotatably connected to the air inlet pipe 33 via a bearing, allowing the rotating shaft 351 to rotate relative to the air inlet pipe 33. The fan blades 352 are fixedly connected to the rotating shaft 351. When the upward gas acts on the fan blades 352, a tangential force is applied to the fan blades 352, causing the fan blades 352 to rotate relative to the air inlet pipe 33. The fan blades 352 thus disturb the water in the mixed liquid chamber, thereby increasing the upward path of the gas, reducing the volume of the bubbles, and improving the dissolution of the boron oxide particles in the gas.

[0045] like Figure 4 As shown, in one embodiment, the radial direction of the fan blade 352 is set at an angle to the radial direction of the rotating shaft 351. Furthermore, the angle between the radial direction of the fan blade 352 and the radial direction of the rotating shaft 351 ranges from 15° to 45°.

[0046] The radial direction of blades 352 is angled relative to the radial direction of rotating shaft 351. That is, blades 352 are tilted relative to the horizontal plane. This allows the force exerted on blades 352 by the rising gas to be divided into a force perpendicular to the plane of blades 352 and a force along the plane of blades 352. The force along the plane of blades 352 propels blades 352 to rotate about inlet pipe 33. The angle between the radial direction of blades 352 and the radial direction of rotating shaft 351 is set to 15°-45° to achieve optimal rotation of blades 352 relative to inlet pipe 33 during the rising process. Specifically, the angle of blades 352 can be 15°, 30°, or 45°.

[0047] like Figure 3 and Figure 4 As shown, in one embodiment, the fan blades 352 are provided in multiple layers along the axial direction of the rotating shaft 351. By providing multiple layers of fan blades 352 on a rotating shaft 351, the turbulence of the fan blades 352 on the water flow in the mixed liquid chamber is enhanced, thereby further ensuring the dissolution of the boron oxide particles in the gas in the water.

[0048] like Figure 3 As shown, in one embodiment, a plurality of baffles 350 are provided at intervals along the axial direction of the air inlet pipe 33. By providing a plurality of baffles 350 in the axial direction of the air inlet pipe 33, the upward floating path of the gas and the turbulence of the water flow are further increased, thereby allowing the boron oxide in the gas to be fully dissolved.

[0049] like Figure 1As shown, a tail exhaust treatment system includes the above-mentioned liquid mixing device 300. The tail exhaust treatment system includes a cooling bottle 200, a liquid mixing device 300, a valve body 400 and a pump 500. The cooling bottle 200 includes an air inlet and an air outlet, and the air inlet is connected to the exhaust port of the furnace body 100; the air inlet pipe 33 of the liquid mixing device 300 is connected to the air outlet of the cooling bottle 200; the valve body 400 is connected to the air outlet pipe 340; and the pump 500 is connected to the valve body 400.

[0050] By connecting the air inlet of the cooling bottle 200 to the exhaust port of the furnace body 100, the exhaust gas discharged from the furnace body 100 is cooled by the coolant in the cooling bottle 200. The air outlet of the cooling bottle 200 is connected to the air inlet pipe 33 of the liquid mixing device 300, so that the exhaust gas cooled by the coolant in the cooling bottle 200 passes through the liquid mixing device 300 to dissolve the boron oxide and then passes to the pump 500 through the valve body 400. As a result, the exhaust gas pressurized by the pump 500 contains less boron oxide, which reduces the maintenance of the pump 500 and the back-end management, reducing maintenance time and cost.

[0051] like Figure 1 As shown, in one embodiment, there are multiple liquid mixing devices 300, and the multiple liquid mixing devices 300 are arranged at intervals. By providing multiple liquid mixing devices 300 in the tail gas treatment system, the tail gas containing boron oxide powder particles can dissolve as much boron oxide as possible after passing through the multiple liquid mixing devices 300. As a result, the boron oxide particles contained in the gas leading to the valve body 400 and the pump 500 are minimized, thereby reducing the maintenance of the pump 500 and the back-end management, and reducing maintenance time and cost.

[0052] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
