[0002] Venturi scrubbers are widely used in coal chemical industry, power engineering and other fields to purify dusty gas. It fully mixes gas and liquid at the throat, and uses the atomization of liquid and the inertial collision of dust particles to achieve efficient separation and removal of dust particles in the gas. Due to the complex composition of the treated gas, some corrosive substances, and the low pH value of the washing water, the inner wall anti-corrosion lining or surfacing layer of the Venturi scrubber is easily corroded, and then corrodes the shell base material.

[0003] The internal parts of existing Venturi scrubbers are usually fixedly connected to the shell. Once the internal parts are damaged or need to be replaced, the entire equipment often needs to be disassembled, which not only increases the difficulty of maintenance, but may also cause damage to other parts of the equipment. In addition, due to its complex internal structure, disassembly, inspection, maintenance and replacement are relatively difficult, which requires a lot of time and manpower, increasing the company's operating costs.

[0011] In a preferred embodiment of the internal part replacement device of the present invention: one end of the contraction section is connected to the diffusion section, and an air hole is provided at the connection between the contraction section and the diffusion section.

[0012] In a preferred embodiment of the internal component replacement device of the present invention: the diameter of the air hole is smaller than the diameter of the straight cylinder.

[0013] In a preferred embodiment of the internal component replacement device of the present invention: one end of the tube body away from the fixing plate is an injection point, and the injection point extends into the diffusion section inside the throat.

[0023] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with specific implementation methods and drawings.

[0024] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may vary according to the intention of a person of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as a general description based on the meaning of the terms and the present invention.

[0025] Reference Figure 1 to Figure 4 The present embodiment provides an internal parts replacement device, comprising an inner sleeve 1, including a straight cylinder 11, a throat 12 connected to the straight cylinder, a mounting plate 13 connected to the throat 12, and a clamping member 14 arranged on the outer wall of the straight cylinder 11; a water spray pipe 2, comprising a tube body 21 and a fixing plate 22 arranged on the outer wall of the tube body 21; the mounting plate 13 is fixed between the flanges of the scrubber, and the straight cylinder 11 is fastened by the clamping member 14, so that the inner sleeve 1 is installed inside the scrubber for easy disassembly and inspection; the fixing plate 22 can install the water spray pipe 2 on the outer wall of the scrubber for easy disassembly and replacement.

[0026] The inner sleeve 1 is arranged inside the air inlet pipe 31, and the mounting plate 13 is clamped between the flanges connecting the air inlet pipe 31 and the elbow 32; the straight cylinder 11 is the main component of the inner sleeve 1, which can ensure the smooth entry of gas and make the gas flow smoother and more stable; the throat 12 is connected to the straight cylinder 11, and is the key part of gas-liquid mixing. The design of the throat 12 increases the gas flow rate; the fixing plate 22 is fixedly connected to the outer wall of the water spray pipe 2, and the fixing plate 22 can be connected to the flange of the outer wall of the water inlet pipe 34, so as to install the water spray pipe 2.

[0027] As an optional embodiment, the clamping member 14 includes a plurality of support blocks 141 equidistantly arranged on the outer wall of the straight tube 11 .

[0028] like Figure 2 As shown, a plurality of support blocks 141 are fixedly connected to the outer wall of the straight cylinder 11; the support blocks 141 are preferably arranged in four numbers, which are equidistantly arranged on the outer wall of the straight cylinder 11 to form a uniformly distributed support structure, so that when the clamping member 14 is tightening the straight cylinder 11, the stress is evenly distributed on the outer wall, avoiding stress concentration, thereby improving the durability and reliability of the inner sleeve 1.

[0029] As an optional embodiment, the straight tube 11 is communicated with the inside of the throat 12 .

[0030] The straight tube 11 is connected to the inside of the throat 12 to form a continuous fluid channel, ensuring that the gas and the washing liquid can pass through the inner sleeve 1 smoothly, so that the gas can be gradually accelerated when entering the throat 12, achieving the best gas-liquid mixing effect.

[0031] As an optional embodiment, the throat 12 includes a contraction section 121 connected to one end of the straight tube 11 , and the end of the contraction section 121 away from the straight tube 11 is inclined toward the center of the inner sleeve 1 .

[0032] The design of the contraction section 121 being inclined toward the center of the circle can make the gas form a centripetal flow inside the throat 12, making the gas flow smoother, reducing the energy loss of the gas during the flow process, and facilitating the uniform distribution of the scrubbing liquid and the mixing of gas and liquid.

[0033] As an optional embodiment, a diffuser section 122 is provided at one end of the mounting plate 13 , and an end of the diffuser section 122 away from the mounting plate 13 is inclined toward the center of the inner sleeve 1 .

[0034] In the diffuser section 122, the gas flow rate is reduced, which is conducive to gas-liquid separation. Water droplets in the washing liquid settle under the action of gravity and are separated from the purified gas, thereby improving the washing effect. The design of the diffuser section 122 inclined toward the center of the inner sleeve 1 helps to optimize the flow path of the fluid, reduce the resistance of the fluid in the diffuser section, and improve the flow efficiency of the fluid.

[0035] As an optional embodiment, one end of the contraction section 121 is connected to the diffusion section 122 , and an air hole 123 is provided at the connection between the contraction section 121 and the diffusion section 122 .

[0036] The design of the air hole 123 forms a local fluid channel between the contraction section 121 and the diffusion section 122, which helps to adjust the flow characteristics of the fluid; through the air hole 123, the flow of gas between the contraction section 121 and the diffusion section 122 can be controlled to ensure that the flow of the fluid inside the throat 12 is smoother.

[0037] As an optional embodiment, the diameter of the air hole 123 is smaller than the diameter of the straight cylinder 11 .

[0038] Since the diameter of the air hole 123 is smaller than the diameter of the inner wall of the straight tube 11, the flow rate of the fluid passing through the air hole 123 can be increased. At the same time, the air hole 123 can form a local negative pressure area inside the throat 12, which is more conducive to the atomization of the washing liquid and the mixing of gas and liquid.

[0039] As an optional embodiment, one end of the tube body 21 away from the fixing plate 22 is an injection point 211 , and the injection point 211 extends into the diffusion section 122 inside the throat 12 .

[0040] The injection point 211 extends into the diffusion section 122, which can make the washing liquid fully contact with the high-speed gas. In the diffusion section 122 of the throat 12, the gas flow rate gradually decreases and the pressure gradually recovers. The injection point 211 can make the washing liquid spray in the area with lower gas flow rate, which is more conducive to forming a more uniform gas-liquid mixture, thereby enhancing the dust removal effect.

[0041] When in use, the mounting plate 13 is fixed between the flanges of the scrubber, the straight cylinder 11 is fastened by the clamping piece 14, the inner sleeve is installed inside the air inlet pipe 31, and the fixing plate 22 is connected to the flange on the outer wall of the water inlet pipe 34, and the water spray pipe 2 is installed, so that the inner sleeve 11 and the water spray pipe 2 are easy to disassemble, assemble and replace, making the maintenance of the equipment more convenient, reducing the equipment downtime, and improving the operation efficiency of the equipment.

[0042] Reference Figure 1 to Figure 4 The present embodiment provides a venturi scrubber, including a main body assembly 3, including an air inlet pipe 31 movably arranged on the outer wall of the inner sleeve 1, a curved pipe 32 arranged on the outer wall of the air inlet pipe 31, an air outlet pipe 33 arranged on the outer wall of the curved pipe 32, and a water inlet pipe 34 arranged on the outer wall of the curved pipe 32.

[0043] The air inlet pipe 31 introduces the dust-containing gas from the front-end equipment into the scrubber to ensure that the gas can smoothly enter the throat pipe 12 for treatment. The design of the elbow 32 allows the gas to smoothly turn and enter the throat pipe 12 after entering from the air inlet pipe 31, which helps to optimize the flow path of the gas and reduce the formation of turbulence and eddy currents. The curvature design of the elbow 32 helps to reduce the direct impact and scouring of the fluid on the pipe wall, reduce the wear and corrosion rate of the inner wall, and extend the service life of the equipment; the air outlet pipe 33 discharges the purified gas after the scrubbing treatment out of the scrubber and enters the subsequent process flow or is discharged into the atmosphere; the water inlet pipe 34 is fixedly connected to the outer wall of the elbow 32 and is internally connected. The water inlet pipe 34 introduces the washing liquid into the scrubber and supplies it to the water spray pipe 2 for use. The washing liquid is sprayed into the throat pipe 12 through the water spray pipe 2 and is fully mixed with the dust-containing gas to achieve a dust removal effect.

[0044] As an optional embodiment, one end of the curved pipe 32 is connected to the air inlet pipe 31 through a flange, and the other end is connected to the air outlet pipe 33 through a flange, and the mounting plate 13 is fixed between the air inlet pipe 31 and the curved pipe 32 .

[0045] The flange connection method not only ensures the sealing and reliability of the connection, but also facilitates disassembly and maintenance, reducing equipment downtime. The elbow 32 is a part of the main component 3. Its modular design allows the elbow 32 to be replaced alone when a certain part of the scrubber is replaced or upgraded, without the need for large-scale disassembly and modification of the entire equipment, reducing maintenance costs and workload.

[0046] In summary, the design of the elbow 32 can avoid stress concentration areas such as right angles or sharp angles, so that the stress generated by the fluid during the flow process is more evenly distributed on the pipe wall, reducing the problem of excessive local stress, thereby reducing the fatigue damage and corrosion risks of the equipment, improving the durability of the equipment, optimizing the flow path of gas and liquid, improving the dust removal efficiency of the scrubber, and ensuring the stable operation and convenient maintenance of the equipment.

[0047] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
