Description

Technical Field

[0001] This utility model relates to the field of dynamic wave desulfurization and dust removal equipment, and more specifically, to a turbulent dynamic wave desulfurizing agent injection device. Background Technology

[0002] Sulfur-containing flue gas (mainly containing SO2, SO3, H2S, etc.) is a harmful gas produced by industrial combustion (such as coal, petroleum, metallurgy, chemical industry, etc.), which easily forms acid rain (pH < 5.6) and corrodes equipment.

[0003] Existing sintering kilns primarily treat high-dust and high-sulfur flue gas using empty tower spray desulfurization. However, due to the large size of the empty tower spray equipment, the required coverage area, liquid-to-gas ratio, and pump head are very high, resulting in significant electricity waste. The manufacturing and operating costs are also relatively high, making it unsuitable for production operations. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a turbulent dynamic wave desulfurizing agent injection device. Through the cooperation of the tail inlet pipe and swirl blades, untreated flue gas is drawn into the fixed inlet pipe and violently mixed with desulfurizing liquid. The desulfurizing liquid generates intense turbulence and forms foam. The foamed desulfurizing liquid impacts the flue gas in the opposite direction. The contact surface between the gas and liquid phases at the interface is extremely large and the interface renewal rate is fast, thereby achieving a highly efficient mass transfer process, and acidic gases and dust are effectively removed.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example

[0020] Please see Figs. 1-3A turbulent dynamic wave desulfurizer injection device includes: a reverse spray pipe 1, a reverse spray inlet 2 extending from the top surface of the reverse spray pipe 1, a through hole on one side of the outer wall of the reverse spray inlet 2, and an installation port on one side of the outer wall of the reverse spray pipe 1; and a jet water vapor mixing component, the jet water vapor mixing component including: a water spraying component and an air intake component, the water spraying component including: an air intake fixed pipe 3, a middle air intake pipe 4, a tail air intake pipe 5, and a jet water vapor mixing nozzle 6, the air intake fixed pipe 3 being installed in the through hole, the middle air intake pipe 4 being installed at one end of the air intake fixed pipe 3, the tail air intake pipe 5 being installed at one end of the middle air intake pipe 4, the jet water vapor mixing nozzle 6 being installed at the output end of the tail air intake pipe 5, and the air intake component being disposed on one side of the reverse spray pipe 1 for introducing the mixture.

[0021] In a specific embodiment of this utility model, the desulfurizing agent is delivered to the inlet pipe 7 at high pressure and high flow rate using an existing desulfurization pump. At the middle air inlet pipe 4, the cross-sectional area of ​​the inlet pipe 7 is significantly reduced due to the occupation of the tail air inlet pipe 5, resulting in increased flow velocity. Under the action of the swirl vanes, it enters a faster swirling state, spraying backward and creating negative pressure. This draws untreated flue gas from the reverse spray inlet 2 into the fixed air inlet pipe 3, where it mixes violently with the desulfurization liquid. Due to the asymmetry of the fixed air inlet pipe 3, the middle air inlet pipe 4, and the tail air inlet pipe 5, the increased cross-sectional area of ​​the rear pipe leading to slower flow velocity and increased pressure, as well as the rotational force of the water, intense turbulence is formed in this area. The water is violently mixed to form foam. The foamed desulfurizing agent flows through the elbow and is injected into the distributor 8. Under pressure, it is rapidly distributed to each spray head 9. The spray head 9 cuts, accelerates, and pressurizes the desulfurizing agent again, and finally sprays it out at high speed. The foamed desulfurizing liquid sprayed out impacts the flue gas entering the reverse spray pipe 1 in the opposite direction. This reverse impact eventually reaches pressure equilibrium. Due to the principle of gas-liquid momentum balance, a uniform turbulent reaction zone with up-and-down fluctuations is formed at the liquid-gas equilibrium contact surface, which is called the foam zone. In this zone, the contact surface between the gas and liquid phases at the interface is extremely large and the interface renewal rate is fast, thereby realizing an efficient mass transfer process. Acidic gases and dust are effectively removed.

[0022] Specifically, the air intake components include: a water inlet pipe 7, a distributor 8, and multiple injection heads 9. The water inlet pipe 7 is installed inside the through-hole, the distributor 8 is installed at the output end of the water inlet pipe 7, and the multiple injection heads 9 are all installed at the output end of the distributor 8.

[0023] In this embodiment, the desulfurizing agent is introduced through the water inlet pipe 7 and the desulfurization pump. The distributor 8 is used to distribute the introduced foamy desulfurizing agent so that it is sprayed out from the spray head 9. The spray head 9 is a high-flow swirling high-speed solid cone spray head, which cuts, accelerates and pressurizes the desulfurizing agent so that it is sprayed out at high speed.

[0024] Specifically, the top surface of the water inlet pipe 7 has a mating hole.

[0025] In this embodiment, the tail air intake pipe 5 is fixed by a mating hole, and the dead water inlet pipe 7 is connected to the tail air intake pipe 5.

[0026] Specifically, the outer wall of the jet water vapor mixing nozzle 6 is provided with multiple swirl blades.

[0027] In this embodiment, the desulfurizing agent is cut by swirl blades, causing it to rotate.

[0028] Specifically, the outer wall of the water inlet pipe 7 is fitted with a connecting flange.

[0029] In this embodiment, a connecting flange is used to connect the inlet pipe 7 to the existing desulfurization pump.

[0030] Specifically, it mates with the fitting hole and the tail intake pipe 5.

[0031] In this embodiment, the tail intake pipe 5 is accommodated by a mating hole and sealed to prevent leakage.

[0032] Working principle: The desulfurizing agent is delivered to the inlet pipe 7 at high pressure and high flow rate using the existing desulfurization pump. At the middle air inlet pipe 4, the cross-sectional area of ​​the inlet pipe 7 is significantly reduced due to the occupation of the tail air inlet pipe 5, increasing the flow velocity. Under the action of the swirl vanes, it enters a faster swirling state, spraying backward and creating negative pressure. This draws the untreated flue gas from the reverse spray inlet 2 into the fixed air inlet pipe 3, where it mixes violently with the desulfurization liquid. Due to the asymmetry of the fixed air inlet pipe 3, the middle air inlet pipe 4, and the tail air inlet pipe 5, the increased cross-sectional area of ​​the rear pipes leading to slower flow velocity and increased pressure, as well as the rotational force of the water, intense turbulence is formed in this area, causing the water to... Intense mixing creates foam, and the foamed desulfurizing agent flows through the elbow and is injected into the distributor 8. Under pressure, it is rapidly distributed to each spray head 9. The spray head 9 further cuts, accelerates, and pressurizes the desulfurizing agent, finally spraying it out at high speed. The foamed desulfurizing liquid sprayed out impacts the flue gas entering the reverse spray pipe 1 in the opposite direction. This reverse impact eventually reaches pressure equilibrium. Due to the principle of gas-liquid momentum balance, a uniform turbulent reaction zone with up-and-down fluctuations is formed at the liquid-gas equilibrium contact surface, which is called the foam zone. In this zone, the contact surface between the gas and liquid phases at the interface is extremely large, and the interface renewal rate is fast, thereby achieving a highly efficient mass transfer process. Acidic gases and dust are effectively removed.

[0033] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
