Description

Technical Field

[0001] This utility model relates to the field of float glass manufacturing technology, and in particular to a gas processing device. Background Technology

[0002] In a float glass production line, molten glass is formed into flat glass strips in a tin bath. These flat glass strips then undergo a cold-end cutting process after being processed in an annealing furnace to finally form flat glass sheets. Between the tin bath and the annealing furnace is a slag box, above which is a transition roller table. As the flat glass strip is supported and conveyed by the transition roller table, its lower surface comes into contact with the transition rollers on the table, potentially resulting in scratches on the lower surface.

[0003] In recent years, sulfur dioxide gas has been sprayed onto the lower surface of flat glass ribbons on the transition roller table. At high temperatures, the sulfur dioxide gas reacts with Na ions in the glass composition to generate a thin film of sodium sulfate and sodium sulfite, which buffers and protects the flat glass ribbon. However, sulfur dioxide gas can easily escape in large quantities into the factory, damaging the steel structure and even posing occupational health hazards to employees. Therefore, there is an urgent need to propose a solution to these problems. Utility Model Content

[0004] The purpose of this invention is to provide a gas treatment device to solve the problem of large-scale leakage of sulfur dioxide gas at the slag box in the prior art.

[0005] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0006] A gas treatment device includes suction components, suction pipes, and a suction fan. The suction pipe is located above a transition roller table and extends along the conveying direction of the transition roller table.

Each suction component has an air inlet at its lower end and its upper end communicates with the suction pipe. The suction port of the suction fan communicates with the suction pipe, and the air outlet of the suction fan is used to communicate with a desulfurization tower. The gas treatment device also includes multiple curtain assemblies, which are spaced apart along the length of the suction pipe on its lower side.

[0017] This utility model proposes a gas treatment device, including a suction component, a suction pipe, and a suction fan. The suction pipe is located above the transition roller table and extends along the conveying direction of the transition roller table. Multiple suction components are spaced apart on the lower side of the suction pipe along the length direction of the suction pipe.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] This embodiment proposes a gas treatment device to solve the problem of large-scale leakage of sulfur dioxide gas at the slag box in the prior art.

[0031] like Figure 1 As shown, the gas treatment equipment includes an air intake component 1, an air intake pipe 2, and an air intake fan 3. The air intake pipe 2 can be located above the transition roller table 100 and extends along the conveying direction of the transition roller table 100. Multiple air intake components 1 are spaced apart on the lower side of the air intake pipe 2 along the length direction of the air intake pipe 2. The lower end of the air intake component 1 has an air inlet, and the upper end is connected to the air intake pipe 2. The air intake port of the air intake fan 3 is connected to the air intake pipe 2, and the air outlet of the air intake fan 3 is used to connect to the desulfurization tower 300. The gas treatment equipment also includes multiple curtain assemblies 4. Multiple curtain assemblies 4 are spaced apart on the lower side of the air intake pipe 2 along the length direction of the air intake pipe 2, and the air intake component 1 is located between two adjacent curtain assemblies 4. The lower side of the curtain assembly 4 can be spaced at a preset distance from the transition roller 200 on the transition roller table 100.

[0032] It is worth noting that in the float glass production line, molten glass floats on top of molten tin in the tin bath, gradually forming a flat glass strip. The flat glass strip needs to pass through a slag box and then be transported to an annealing furnace for annealing, followed by cold-end cutting to form glass sheets. A transition roller table 100 is installed on the upper side of the slag box, and a transition roller 200 is rotatably mounted on the transition roller table 100. The transition roller 200 is connected to a power mechanism, which drives the transition roller 200 to rotate, thus transferring the flat glass strip from the tin bath to the annealing furnace. The slag box is also equipped with an adjustable sulfur dioxide jetting device, used to spray sulfur dioxide gas onto the underside of the flat glass strip. At high temperatures, the sulfur dioxide gas reacts with Na ions in the glass composition to generate a thin film of sodium sulfate and sodium sulfite, which buffers and protects the flat glass strip. However, sulfur dioxide waste gas can easily escape in large quantities into the factory building, damaging the steel structure and even posing occupational health hazards to the employees.

[0033] In this embodiment, by installing suction components 1 at intervals below the suction pipe 2, when the suction fan 3 is started, the sulfur dioxide waste gas in the slag box can be sucked into the suction pipe 2 by the suction components 1 and discharged to the desulfurization tower 300 for desulfurization treatment, effectively reducing the sulfur dioxide content in the factory. The desulfurization tower 300 is an inherent building in the glass factory, and the waste gas generated in the glass kiln can be introduced into the desulfurization tower 300 for desulfurization treatment. In this embodiment, the sulfur dioxide waste gas absorbed by the suction pipe 2 is discharged to the desulfurization tower 300 for treatment, eliminating the need to set up new desulfurization equipment, greatly improving the convenience of desulfurization, and saving factory construction costs. In addition, by setting up curtain components 4 and installing suction components 1 between two adjacent curtain components 4, the curtain components 4 can effectively prevent sulfur dioxide waste gas from leaking from the gap between the suction components 1 and the slag box, and can also effectively prevent sulfur dioxide waste gas from leaking from the gap between the suction components 1, thereby improving the processing efficiency of the gas treatment equipment.

[0034] Optionally, the suction element 1 is funnel-shaped, and the small end of the suction element 1 is connected to the suction pipe 2. This arrangement allows the large end of the suction element 1 to face the transition roller table 100, thereby improving the suction effect of sulfur dioxide waste gas in the slag box and improving the reliability of the gas treatment equipment.

[0035] For example, the suction fan 3 is a centrifugal fan. The centrifugal fan relies on the rotation of the impeller to generate centrifugal force, which draws gas in from the suction port and discharges it in the radial direction. It has a simple structure and reliable operation, which improves the reliability of the gas handling equipment.

[0036] Of course, other types of fans can be used in other embodiments, as long as they operate reliably, and no further restrictions are imposed here.

[0037] Optionally, the curtain assembly 4 includes a curtain and a mounting base. The mounting base is vertically mounted on the suction pipe 2, the upper side of the curtain is mounted on the mounting base, and the lower side is spaced at a preset distance from the transition roller 200. Understandably, the curtain not only effectively prevents the protective gas in the tin bath or annealing furnace from leaking through the opening, but also blocks sulfur dioxide waste gas in the slag box. These features facilitate the easy retraction of the curtain at any time. Furthermore, it allows for adjustment of the curtain's droop according to the thickness of the flat glass strip, ensuring good gas blocking effect when producing flat glass strips of different sizes.

[0038] For example, the curtain is made of fiberglass cloth. This design improves the curtain's insulation, heat resistance, and corrosion resistance, thereby enhancing the reliability of the gas handling equipment.

[0039] Of course, in other embodiments, the curtain can also be made of other materials, as long as it can meet the requirements of insulation, heat resistance and corrosion resistance and be suitable for the float glass production line environment. No further restrictions are imposed here.

[0040] Optionally, the curtain is sheet-like, and the thickness direction of the curtain is perpendicular to the axial direction of the transition roller 200. This arrangement facilitates the curtain to block the openings of the tin bath and annealing furnace in a surface-blocking manner. In addition, this arrangement allows the thickness direction of the curtain to be consistent with the arrangement direction of the suction element 1, thereby facilitating cooperation with the suction element 1.

[0041] Optionally, the mounting base is elongated, with its length parallel to the axial direction of the transition roller 200. The mounting base has a groove along its length, in which the curtain slides. This design facilitates the disassembly and retraction of the curtain, making it easier to replace. It also allows for adjustment of the curtain width to accommodate different sizes of transition roller tables 100, thus improving the reliability and adaptability of the gas treatment equipment.

[0042] Optionally, the curtain assembly 4 also includes a base, a sliding rod, and a lead screw. The base has a sliding hole and a threaded hole. The sliding rod slides into the sliding hole, and the lead screw engages with the threaded hole. The lower end of the sliding rod is connected to the mounting base, and the lead screw is rotatably mounted on the mounting base. This configuration allows the mounting base to be raised and lowered by rotating the lead screw. Simultaneously, because of the sliding rod, the mounting base does not rotate, thus facilitating the raising and lowering of the curtain. This allows the curtain to adapt to flat glass strips of different thicknesses and to transition roller tables 100 of different heights, improving the reliability of the gas handling equipment and the user experience.

[0043] Optionally, a grip is provided at the end of the screw away from the mounting base. This feature facilitates gripping and rotating the screw, improving the ease of use of the curtain assembly 4.

[0044] For example, the grip is a handwheel, which is coaxially connected to the lead screw. This design facilitates operation of the lead screw, reduces the difficulty of raising and lowering the curtain assembly 4, and thus improves the user experience.

[0045] Of course, other gripping components may be used in other embodiments, and no further restrictions are imposed here.

[0046] Optionally, the gas treatment equipment also includes a gas transmission pipe 5, one end of which is connected to the outlet of the suction fan 3, and the other end is used to connect to the lower side of the desulfurization tower 300. This arrangement facilitates the connection between the suction fan 3 and the desulfurization tower 300, thereby improving the adaptability of the gas treatment equipment to the working environment.

[0047] For example, an electric valve 6 is installed on the gas transmission pipe 5 to control the opening and closing of the gas transmission pipe 5. This setting can control whether the gas transmission pipe 5 transmits gas as needed, thereby determining whether to perform desulfurization operation according to the working status of the desulfurization tower 300, and improving the reliability of the gas treatment equipment.

[0048] For example, the gas treatment equipment also includes a mounting frame 7, which is installed inside the float glass production line plant. The mounting frame 7 has an installation platform on its upper side, on which the suction fan 3 is mounted. The suction pipe 2 is fixed to the roof beam of the plant and is at the same height as the suction fan 3 on the mounting platform. This arrangement facilitates positioning the suction pipe 2 above the slag box, thereby facilitating the alignment of the lower end of the suction component 1 with the transition roller table 100. Simultaneously, the suction pipe 2 easily connects to the suction fan 3 on the mounting frame 7, improving the structural rationality of the gas treatment equipment.

[0049] For example, a ladder is provided on the mounting frame 7. This arrangement facilitates the maintenance of the suction fan 3 and the connection between the suction fan 3 and the suction pipe by the staff, thereby improving the reliability of the gas handling equipment.

[0050] As is generally the case, the desulfurization tower 300 is connected to a kiln exhaust gas inlet pipe 400 at its lower side and a flue gas outlet pipe 500 at its upper side. Both the kiln exhaust gas inlet pipe 400 and the flue gas outlet pipe 500 are equipped with electric valves 6 to control the entry of kiln exhaust gas and the emission of treated flue gas. After the gas is discharged from the desulfurization tower 300 via the gas inlet pipe 5 and the kiln exhaust gas inlet pipe 400, the sulfur dioxide exhaust gas is discharged through the flue gas outlet pipe 500 after treatment by the desulfurization tower 300.

[0051] It is worth mentioning that the desulfurization tower 300 uses a dry desulfurization process. Dry desulfurization is based on the principles of adsorption by adsorbents and chemical absorption, converting sulfur dioxide in the waste gas into soluble compounds. The dry desulfurization process of the desulfurization tower 300 has become a relatively mature technology on the market, and will not be elaborated further here.

[0052] Optionally, the gas treatment equipment also includes a side suction component, which is installed in the slag box and has an air intake that is connected to the air intake of the suction fan 3. This configuration can assist in the suction of sulfur dioxide waste gas in the slag box, thereby improving the waste gas treatment capacity of the gas treatment equipment and enhancing the user experience.

[0053] Optionally, the side suction components are located on both sides of the transition roller table 100 along the conveying direction. This arrangement avoids interference between the side suction components and the transition roller 200, improving the structural rationality of the gas treatment equipment.

[0054] The working process of the gas processing equipment in this embodiment is as follows:

[0055] First, turn on the sulfur dioxide jetting device on the transition roller table 100. Based on the thickness of the transition roller table 100 and the flat glass strip, adjust the suction unit 1 and the hanging curtain to a suitable height. Then, turn on the suction fan 3 and the electric valve 6 on the gas delivery pipe 5 to start the desulfurization operation.
