[0038] Example
[0039] like Figure 1 and Figure 2 As shown, a specific embodiment of the present disclosure provides an exhaust device 100, including a flue 1 and a dust removal mechanism 2, wherein one end of the flue 1 is used to be connected with a reaction device and discharge the flue gas generated by the reaction device, and the other end is provided with a first negative pressure mechanism for forming a negative pressure in the tube cavity of the flue 1; the dust removal mechanism 2 includes a mechanism body 21 and an ash discharge pipe 22, the mechanism body 21 is arranged in the flue 1 and is movably matched with the inner wall surface of the flue 1, and an ash discharge port connected with the tube cavity of the flue 1 is provided on the mechanism body 21, one end of the ash discharge pipe 22 is connected with the ash discharge port, and the other end of the ash discharge pipe 22 passes through the tube wall of the flue 1 and is connected with the outside.
[0040] The reactants in the reaction equipment have volatile components. After the reaction occurs in the reaction equipment and the temperature rises, the volatile substances will enter the flue 1 along with the flue gas generated by the reaction. The first negative pressure mechanism creates negative pressure in the tube cavity of the flue 1 to extract the flue gas from the flue 1 to the outside for discharge. The temperature of the flue gas gradually decreases as it flows outward from the flue 1. The volatile substances will settle to form dust and deposit in the flue 1 due to the gradual decrease in temperature. In the present application, the mechanism body 21 moves in coordination with the inner wall surface of the flue 1, collects the dust in the flue 1 through the ash outlet on the mechanism body 21, and discharges the collected dust to the outside of the flue 1 through the ash outlet pipe 22 connected to the ash outlet, thereby ensuring the unobstructed flow of the flue 1.
[0041] In some embodiments, the exhaust device 100 also includes a second negative pressure mechanism 25, which is arranged on the ash discharge pipe 22 and is used to extract the dust collected by the mechanism body 21 to the outside of the flue 1, wherein the first negative pressure mechanism and the second negative pressure mechanism 25 can both use induced draft fans.
[0042] In some embodiments, the ash discharge pipe 22 is made of a telescopic flexible material, and the ash discharge pipe 22 moves along with the movement of the mechanism body 21 in the flue 1 .
[0043] In some embodiments, the mechanism body 21 is a groove-shaped structure, the groove opening of the groove-shaped structure is a dust outlet, and a shovel-shaped structure is formed at the groove opening to facilitate dust to enter the mechanism body 21, thereby improving the dust cleaning efficiency.
[0044] like Figure 3 As shown, in some embodiments, the flue 1 includes a first vertical section 11 and a first horizontal section 12 that are interconnected, the axis of the first vertical section 11 and the axis of the first horizontal section 12 are perpendicular to each other, the first vertical section 11 is relatively close to the reaction device along the axis direction, and the first horizontal section 12 is relatively close to the first negative pressure mechanism along the axis direction. The axis of the first vertical section 11 extends in the vertical direction, and the axis of the first horizontal section 12 extends in the horizontal direction. The flue gas enters from the first vertical section 11 and then enters the first horizontal section 12. In the first vertical section 11, the flue gas is quickly deposited at the connection between the first vertical section 11 and the first horizontal section 12 under the action of gravity, so that most of the dust is accumulated at a fixed position, thereby facilitating the centralized cleaning of the dust in the flue 1, thereby improving the cleaning efficiency of the dust.
[0045] In some embodiments, the mechanism body 21 moves in coordination with the inner wall surface of the first horizontal section 12. The flue gas will continue to settle while flowing in the first horizontal section 12. In other words, most of the volatile substances settle in the first horizontal section 12. It can be seen that the mechanism body 21 can complete the removal of most of the dust in the first horizontal section 12. Based on cost considerations, only the dust removal mechanism 2 is set in the first horizontal section 12 to achieve the effect of unblocking the flue 1.
[0046] In some embodiments, the cross section of the flue 1 is rectangular, the first vertical section 11 includes a left tube wall, a right tube wall, a front tube wall and a rear tube wall, the first horizontal section 12 includes an upper tube wall, a lower tube wall, a front tube wall and a rear tube wall, the cross section of the mechanism body 21 is rectangular and includes an upper groove wall, a lower groove wall, a front groove wall, a rear groove wall and a groove bottom wall, the groove bottom wall is arranged opposite to the groove opening, and an ash discharge pipe 22 is penetrated on the groove bottom wall. Dust is deposited on the lower tube wall of the first horizontal section 12. In the present application, the outer wall surface of the lower groove wall of the mechanism body 21 is attached to and slidably matched with the inner wall surface of the lower tube wall of the flue 1 to completely remove the dust deposited on the lower tube wall of the first horizontal section 12, thereby improving the dust cleaning efficiency.
[0047] In fact, after the flue gas leaves the flue 1, it needs to be processed by the filtering mechanism to reduce the impact on the environment. The volatile substances will not completely form dust and be deposited in the flue 1 during the process of flowing with the flue gas to the outside. A small part of the volatile substances cannot be effectively deposited but flow with the flue gas to the filtering mechanism. The volatile substances flowing to the filtering mechanism will cause the filtering mechanism to be blocked, thereby affecting the filtering effect of the filtering mechanism, and further causing the flue gas emissions to fail to meet the standards.
[0048] In some embodiments, the flue 1 also includes a second vertical section 13 and a second horizontal section 14 which are interconnected, the second horizontal section 14 and the first horizontal section 12 are arranged in parallel and spaced apart, and the second vertical section 13 and the first vertical section 11 are arranged in parallel and spaced apart; the flue 1 also includes a third vertical section 15, a third horizontal section 16 and a fourth vertical section 17, the third vertical section 15 connects the first horizontal section 12 and the third horizontal section 16, the fourth vertical section 17 connects the second horizontal section 14 and the third horizontal section 16, the first vertical section 11 is connected to the reaction equipment, and the fourth vertical section 17 is connected to the first negative pressure mechanism. In the present application, a stepped flue 1 is formed by sequentially connecting a first vertical section 11, a first horizontal section 12, a second vertical section 13, a third horizontal section 16, a third vertical section 15, a second horizontal section 14 and a fourth vertical section 17 to extend the flow time of the flue gas in the flue 1 and increase the number of turns of the flue gas flow direction, so that the volatile substances in the flue gas flow in the flue 1 are completely settled into dust, thereby preventing the flue gas flowing out of the flue 1 from carrying volatile substances and causing blockage of the filtering mechanism.
[0049] In some embodiments, there are two dust removal mechanisms 2 and the mechanism bodies 21 of the two dust removal mechanisms 2 are respectively movably coordinated with the first horizontal section 12 and the second horizontal section 14. The first mechanism body 21 of the first dust removal mechanism 2 is located in the first horizontal section 12, and the second mechanism body 21 of the second dust removal mechanism 2 is located in the second horizontal section 14. The two dust removal mechanisms 2 are respectively used to remove dust deposited in the first horizontal section 12 and the second horizontal section 14, thereby improving the dust cleaning efficiency.
[0050] Since most of the volatile substances will be deposited in the first horizontal section 12, and the first mechanism body 21 is located in the first horizontal section 12, some dust will be accumulated above the first mechanism body 21, and this part of the dust cannot be discharged from the ash outlet and the ash outlet pipe 22 to the outside, thus affecting the dust cleaning effect of the exhaust device 100. In some embodiments, the flue 1 also includes a first extension section 18 connected to the first vertical section 11, the first extension section 18 and the first horizontal section 12 are respectively located on the left and right sides of the lower end of the first vertical section 11, the axis of the first extension section 18 extends in the horizontal direction and is arranged in line with the axis of the first horizontal section 12, and the first mechanism body 21 moves with the inner wall surface of the first extension section 18. In the present application, the first mechanism body 21 is located in the first extension section 18, and when the dust is deposited in the first horizontal section 12, the first mechanism body 21 moves from the first extension section 18 to the first horizontal section 12 to remove the dust, so as to avoid the dust from accumulating above the first mechanism body 21, thereby improving the dust cleaning effect.
[0051] Similarly, in some embodiments, the flue 1 also includes a second extension section connected to the second vertical section 13, the second extension section and the second horizontal section 14 are respectively located on the left and right sides of the lower end of the second vertical section 13, the axis of the second extension section extends in the horizontal direction and is arranged colinearly with the axis of the second horizontal section 14, and the second mechanism body 21 is movably matched with the inner wall surface of the second extension section.
[0052] After the volatile substances settle, small-sized dust and large-sized dust will be formed. The small-sized dust will be cleaned out of the flue 1 by the dust removal mechanism 2. Due to the power of the second negative pressure mechanism 25 of the dust removal mechanism 2, some large-sized dust cannot be extracted into the ash outlet pipe 22. During the movement of the mechanism body 21, this part of the large-sized dust will be pushed by the mechanism body 21. Among them, the first mechanism body 21 moves from right to left to push the dust into the third vertical section 15 and fall into the connection between the third horizontal section 16 and the third vertical section 15, and the second mechanism body 21 moves from left to right to push the dust into the fourth vertical section 17 and fall into the connection between the third horizontal section 16 and the fourth vertical section 17. In some embodiments, the pipe wall at the connection between the third vertical section 15 and the third horizontal section 16 and the pipe wall at the connection between the fourth vertical section 17 and the third horizontal section 16 are both provided with a cleaning port 5, and the cleaning port 5 is provided with a cover plate 6 for opening and closing the cleaning port 5. In the present application, the large-size dust accumulated at the connection between the third horizontal section 16 and the third vertical section 15 and the connection between the third horizontal section 16 and the fourth vertical section 17 is cleaned through the cleaning port 5, thereby improving the dust cleaning effect.
[0053] In some embodiments, the flue 1 further includes a plurality of groups of interconnected horizontal sections and vertical sections, and a dust removal mechanism 2 is provided in each horizontal section. The more horizontal sections and vertical sections there are, the better the dust cleaning effect is.
[0054] Those skilled in the art will appreciate that using horizontal sections and vertical sections with axes perpendicular to each other is a preferred embodiment. In fact, using pipe sections with intersecting axes can enhance the settling of volatile substances.
[0055] In some embodiments, the dust removal mechanism 2 further includes a moving track 23 arranged outside the flue 1, the moving track 23 extends along the axial direction of the flue 1, a running port 19 extending along the axial direction of the flue 1 is provided on the pipe wall of the flue 1, and a moving member 24 passing through the running port 19 is provided on the mechanism body 21, the moving member 24 moves in coordination with the moving track 23, and the moving member 24 is drivingly connected to the driving member. In the present application, the driving member drives the moving member 24 to move on the moving track 23, thereby realizing the movement of the mechanism body 21 in the flue 1 to complete the removal of dust in the flue 1.
[0056] In some embodiments, the moving member 24 is a moving wheel and an axle. The axle passes through the operating port 19 and is connected to the mechanism body 21. The moving wheel is arranged at the end of the axle. The driving member is a driving motor, which drives the moving wheel to rotate.
[0057] In order to maintain the negative pressure in the flue 1, the flue 1 needs to be airtight. In some embodiments, a sealing component is provided on the outer wall of the flue 1. The sealing component is made of a flexible material and can cover the operation port 19. In the present application, the moving member 24 will push the sealing component away during the movement to avoid interference of the sealing component with the moving member 24.
[0058] like Figure 4 As shown, in some embodiments, the sealing assembly includes a plurality of sealing strips 3, which are arranged in sequence along the extension direction of the running port 19, and there is an overlapping portion between adjacent sealing strips 3, one end of the sealing strip 3 is fixed on the outer wall surface of the pipe wall of the flue 1 and is located above the running port 19, and the other end of the sealing strip 3 covers the running port 19 under the action of gravity. In the present application, when the moving member 24 moves to the position of any sealing strip 3, the sealing strip 3 is pushed away by the moving member 24, and the other sealing strips 3 still cover the running port 19 to achieve the sealing of the running port 19, thereby maintaining the sealing of the flue 1.
[0059] In some embodiments, the width of the sealing strip 3 along the extension direction of the operating port 19 is the same as the width of the moving member 24 along the extension direction of the operating port 19, so that the moving member 24 only pushes open one sealing strip 3 each time, thereby maintaining the sealing of the flue 1.
[0060] The working principle of the first negative pressure mechanism is to form a negative pressure in the flue 1 to suck the flue gas generated by the reaction equipment. To ensure the efficiency of sucking out the flue gas, the first negative pressure mechanism needs to maintain the negative pressure at the air inlet of the flue 1 at a set value. When dust accumulates in the flue 1, it will reduce the absolute value of the negative pressure at the air inlet of the flue 1. The first negative pressure mechanism needs to increase the power to maintain the absolute value of the negative pressure at the air inlet of the flue 1 at the set value. As the power of the first negative pressure mechanism increases, the absolute value of the negative pressure on the side of the dust accumulation position close to the first negative pressure mechanism increases, and the absolute value of the negative pressure on the side of the dust accumulation position close to the reaction equipment returns to the set value. In other words, the dust accumulation position in the flue 1 can be determined by detecting the absolute value of the negative pressure in the flue 1, that is, the dust accumulation position is between the position where the absolute value of the negative pressure is greater than the set value and the position where the absolute value of the negative pressure returns to the set value.
[0061] In some embodiments, the exhaust device 100 further includes a control unit and a plurality of negative pressure detection members 4, which are arranged at intervals on the flue 1 and are used to detect the negative pressure value in the flue 1. The control unit is configured to determine the dust accumulation position in the flue 1 according to the detection value of the negative pressure detection member 4. In the present application, when the detection value of a certain negative pressure detection member 4 increases, dust accumulation occurs between the arrangement position of the negative pressure detection member 4 and the arrangement position of the next negative pressure detection member 4 close to the side of the reaction device and with the same detection value, so as to select a method of opening the dust cleaning port 5 or starting the dust removal mechanism 2 according to the dust accumulation position, thereby improving the degree of automation and refinement of the exhaust device 100.
[0062] In some embodiments, after starting the dust removal mechanism 2 to clean the dust at the dust accumulation position, when the detection value of the negative pressure detection component 4 with an increased detection value gradually returns to the design value, the dust removal mechanism 2 is closed to complete the cleaning of the dust in the flue 1; after starting the dust removal mechanism 2 to clean the dust at the dust accumulation position, when the detection value of the negative pressure detection component 4 with an increased detection value has not returned to the design value, the dust removal mechanism 2 is closed and the cleaning port 5 is opened to clean the dust at the dust accumulation position until the detection value of the negative pressure detection component 4 with an increased detection value gradually returns to the design value.
[0063] In some embodiments, the number of negative pressure detection elements 4 is at least three, and the three negative pressure detection elements 4 are respectively arranged on the first horizontal segment 12, the second horizontal segment 14, and the third horizontal segment 16. Most dust will accumulate on the first horizontal segment 12, the second horizontal segment 14, and the third horizontal segment 16. Based on cost considerations, only the negative pressure detection elements 4 are arranged on the first horizontal segment 12, the second horizontal segment 14, and the third horizontal segment 16 to complete the determination of the dust accumulation position.
[0064] The embodiment of the present disclosure also provides a neutral borosilicate glass processing system, including an exhaust device 100, a kiln and a kiln pressure regulating device 200, wherein the kiln is connected to one end of the flue 1 as a reaction device; the kiln pressure regulating device 200 is arranged in the flue 1 and close to the first negative pressure mechanism. Since the neutral borosilicate glass processing system adopts all embodiments of the exhaust device 100, the neutral borosilicate glass processing system has all the beneficial effects brought by the exhaust device 100. The volatile substances discharged with the flue gas are completely settled through the flue 1 of the exhaust device 100, so that the flue gas discharged by the neutral borosilicate glass meets the emission standards.
[0065] The kiln is used for hot-melt processing of neutral borosilicate glass. Neutral borosilicate glass contains volatile components such as boron, potassium, and sodium. After the neutral borosilicate glass is heated in the kiln, volatile substances such as boron, potassium, and sodium will enter the flue 1 along with the smoke generated by the hot melt, and gradually settle in the flue 1 to form dust as the temperature decreases. During the hot-melt processing of neutral borosilicate glass, the kiln needs to maintain a stable pressure in the kiln, and the kiln pressure regulating device 200 is used to maintain a stable pressure in the kiln. In some embodiments, the neutral borosilicate glass processing system also includes a kiln pressure detection component and a control center. The kiln pressure detection component is used to detect the kiln pressure in the kiln. The control center is electrically connected to the kiln pressure detection component and the kiln pressure regulating device 200 and is configured to adjust the kiln pressure regulating device 200 according to the detection value of the kiln pressure detection component.
[0066] When it is necessary to open the cleaning port 5 to remove dust in the flue 1, the pressure inside the kiln will change. At this time, the kiln pressure regulating device 200 works to maintain the stability of the pressure inside the kiln. However, if the cover plate 6 is opened too quickly, the kiln pressure regulating device 200 will be unable to adjust the pressure inside the kiln in time. Therefore, it is necessary to adjust the opening speed of the cover plate 6 to adapt to the kiln pressure regulating device 200, so as to maintain the stability of the pressure inside the kiln and ensure normal processing in the kiln.
[0067] In some embodiments, the cover plate 6 is movably matched with the flue 1 and driven by a motor. The driving motor of the cover plate 6 is electrically connected to the control center, and the control center adjusts the driving motor to control the opening speed of the cover plate 6.
[0068] In some embodiments, the control unit of the exhaust device 100, the negative pressure detection component 4 of the exhaust device 100, the drive motor of the cover plate 6 of the exhaust device 100, the drive motor of the moving part 24 of the exhaust device 100, the kiln pressure regulating device 200 and the kiln pressure detection component are all electrically connected to the control center, thereby realizing integrated control of the neutral borosilicate glass processing system, thereby improving the degree of automation of the neutral borosilicate glass processing system.
[0069] It can be understood by those skilled in the art that the negative pressure detection element 4 and the kiln pressure detection element can adopt differential pressure transmitters, and the kiln pressure regulating device 200 can adopt kiln pressure gate plates.
