Description

Technical Field

[0001] The invention relates to the technical field of substrate glass production, and in particular to a substrate glass channel cooling system. Background Art

[0002] In the substrate glass industry, the platinum channel directly or indirectly controls the temperature through flange heating to adjust the production process parameters. As cooling water to protect the flange, the reasonable installation and layout of the substrate glass channel cooling pipeline can greatly reduce the difficulty of installation and later maintenance, and better maintain the stability of the process equipment. The existing substrate glass channel cooling pipeline, kiln and platinum channel cooling water tray are set separately, without considering the scientific and economical layout of the cooling pipeline, and it is impossible to achieve the effect of reducing energy loss and saving costs while meeting the process production needs. In addition, after the platinum channel body is used, the copper busbar is energized and the power cannot be cut off during production, otherwise it is easy to cause blockage, resulting in paralysis of the production line. Due to the layout of the platinum channel body, heating flange and external bricks of the body, the installation height of the cooling water pipe of the substrate glass channel is about 3000mm from the ground, and the cooling water pipe is also fixed with a bracket above the flange heating, which is sensitive to changes in water pressure. Therefore, in order to avoid frequent water outages and maintenance operations caused by sudden changes in cooling water flow rate and pressure, the design of the substrate glass channel cooling pipeline must also consider how to keep the cooling water flow smooth to maintain equipment stability and reduce the difficulty of later equipment maintenance. This is not considered in the existing substrate glass channel cooling pipeline. Summary of the invention

DETAILED DESCRIPTION

[0027] To further explain the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings, in which the same reference numerals represent the same components.

[0028] Combined with reference Figure 1-7 The present embodiment provides a substrate glass channel cooling system, including a water inlet main line 1, a water return main line 2, 22-way water inlet branch lines 3, 22-way water return branch lines 4 and a remote controller. The water inlet main line 1 includes a water inlet main line 14 and a water inlet bypass line 16 connected in parallel. The water inlet main line 14 is provided with a butterfly valve (i.e., a first regulating valve 11), a water inlet pressure transmitter 12 and a water inlet temperature transmitter 13. The water inlet bypass line 16 is provided with a butterfly valve (i.e., a second regulating valve 15). The outlet end of the water inlet main line 14 and the outlet end of the water inlet bypass line 16 merge and are connected to the water inlet end of any water inlet branch line 3. Any water inlet branch line 3 is provided with a ball valve (i.e., a third regulating valve 31) and a first stop valve 32. A section of the water outlet of the first stop valve 32 is reserved for connecting with the cooling pipelines of high-temperature equipment such as kiln industrial TV, kiln throat and platinum channel, such as Figure 4 As shown (the inverted U-shaped pipe section is omitted in the figure), any return water branch pipeline 4 includes a return water branch pipe 42 provided with a second stop valve 41 for connecting with the cooling pipeline of the high-temperature equipment, and a first return water pipe 43 and a bypass return water pipe 44 respectively connected to the return water branch pipe 42. The first return water pipe 43 is provided with a ball valve (i.e., a fourth regulating valve 45), a water outlet temperature meter 46 with a transmitter, a water outlet flow meter 47, and a water outlet pressure gauge 48. The bypass return water pipe 44 is provided with a ball valve (i.e., a fifth regulating valve 49). The outlet end of the first return water pipe 43 and the outlet end of the bypass return water pipe 44 are merged and connected to the return water main pipeline 2. Specifically, the first water return pipe 43 includes three fourth regulating valves 45, and the first water return pipe 43 is arranged in the order of the fourth regulating valve 45, the outlet water temperature meter 46 with a transmitter, the outlet water flow meter 47, and the fourth regulating valve 45, and the outlet water side of the outlet water flow meter 47 is connected to a fourth regulating valve 45 and an outlet water pressure meter 48 in sequence through a branch pipe. The remote controller is respectively connected to the inlet water pressure transmitter 12, the inlet water temperature transmitter 13, the outlet water temperature meter 46 with a transmitter, and the outlet water flow meter 47 for remote monitoring. The range of the inlet water pressure transmitter 12 is 0-1Mpa, and the range of the inlet water temperature transmitter 13 is 10-30℃.

[0029] The water inlet end of the water inlet main line 1 is connected to the power water inlet main of the water circulation equipment through a pressure reducing valve (not shown). The pressure of the process circulating water with kinetic energy in the power water inlet main is relatively high. The pressure is adjusted to the pressure required by the process production through the pressure reducing valve. At the same time, to prevent the cooling water pressure from being too high, the hose at the end of the water inlet branch line 3 is flushed open. Figure 2As shown, the 22-way water inlet branch pipeline 3 is uniformly fed with water from the water inlet main pipeline 1. In normal use, the second regulating valve 15 on the water inlet bypass pipe 16 is closed, and the process circulating water (0.2~0.4Mpa) flows into the water inlet main pipe 14 provided with the first regulating valve 11, the water inlet pressure transmitter 12 and the water inlet temperature transmitter 13. When the water inlet main pipe 14 fails or is under maintenance, the second regulating valve 15 is opened to allow water to flow in from the water inlet bypass pipe 16; Figure 3 As shown, during normal use, the fifth regulating valve 49 on the bypass return pipe 44 is closed, and the channel cooling water returns to the return water main line 2 through the first return pipe 43 equipped with a fourth regulating valve 45, a water outlet temperature meter 46 with a transmitter, a water outlet flow meter 47, and a water outlet pressure meter 48. When the first return pipe 43 fails or is under maintenance, the fifth regulating valve 49 is opened to return water from the bypass return pipe 44. The arrangement of the water inlet bypass pipe 16 and the bypass return pipe 44 is conducive to maintaining the stable operation of the substrate glass channel equipment.

[0030] The inlet water pressure transmitter 12, the inlet water temperature transmitter 13, the outlet water temperature meter with transmitter 46, and the outlet water flow meter 47 are all connected to the remote controller, and the corresponding data can be viewed remotely, and the corresponding process parameters can be monitored remotely in real time. When there is a fluctuation or failure, it can be discovered and handled in time. The outlet water temperature meter with transmitter 46 and the outlet water flow meter 47 can remotely monitor the return water temperature and return water flow data. The return water temperature reflects the cooling condition, and the return water flow reflects the cooling capacity. The outlet water pressure gauge 48 is an on-site pressure gauge, and the data can be directly observed during on-site inspection. When the outlet water pressure gauge 48 shows 0, it means that there is no medium flowing in the pipeline.

[0031] In this embodiment, the end section of the return water main line 2 is raised by 200 mm to form an inverted U-shaped pipe section 21. The diameter of the return water main line 2 is larger than the diameter of the inlet water main line 1. The diameter of the return water main line 2 is DN80, and the diameter of the inlet water main line 1 is DN65. The diameter of the return water branch line 4 is larger than the diameter of the inlet water branch line 3. The diameter of the return water branch line 4 is DN20, and the diameter of the inlet water branch line 3 is DN15. Different from the layout height of the furnace electrode cooling water pipe (the ground valve of the furnace electrode cooling water pipe is connected to the electrode cooling water plate with a hose, the height does not exceed 400mm, and the pipe is about 500mm), the installation height of the substrate glass channel cooling water pipe is about 3000mm from the ground, and the cooling water pipe is also fixed by a bracket above the flange heating. Therefore, it is more sensitive to water pressure changes, and the flow rate and pressure cannot change greatly in a short time, so as not to affect the use of equipment. Based on this, in order to increase the efficiency of cooling capacity utilization and control the flow rate of smooth water flow, the diameters of the return water main line 2 and the return water branch line 4 are designed to be larger than the inlet water main line 1 and the inlet water main line 2. While the diameter of the branch pipeline 3 is slightly larger, an inverted U-shaped pipe section 21 is added at the end of the return water main pipeline 2 to further balance the pressure changes caused by different pipe diameters. In addition, the heat dissipation of the later channel body deteriorates, resulting in an increase in the cooling capacity of the incoming water, causing the return water pipeline to return too quickly. Due to the excessive flow rate in the return water pipeline, there is a certain vacuum interval causing air accumulation / residue, affecting the use of the equipment. The inverted U-shaped pipe section 21 can also increase the pipe resistance, slow down the flow rate of the return water main pipeline 2, reduce abnormal noise, and offset the negative impact of opening / closing valves and stopping / delivering water during maintenance operations, further improving the stability of the equipment production process.

[0032] In this embodiment, the water inlet branch pipe 3 is connected to the water inlet main pipe 1, and the water return branch pipe 4 is connected to the water return main pipe 2 by plug welding. The instruments, devices and valves in various places in the pipeline are all connected by flexible joints, which is convenient for later maintenance and disassembly and replacement when the branch pipes are blocked, or the instruments or valves are damaged. For direct pipeline and pipeline welding, if the pipeline is blocked, it is necessary to remove the valves or other pipe fittings, and then cut the pipeline to deal with the blockage. After adding flexible joints, it can be convenient for later maintenance, and replacement can be carried out without cutting the pipeline. At the same time, in daily maintenance, some pipelines can be prefabricated in advance for emergency use, which can respond quickly and replace quickly, reduce downtime, speed up the resumption of production, and maintain equipment stability. Figure 1As shown, the water inlet main line 1 and the water return main line 2 are installed separately on both sides. The installation height of the water return main line 2 of the entire cooling system is higher than the installation height of the water inlet main line 1. The upper left of the figure is the installation position of the water return main line 2, and the lower right is the installation position of the water inlet main line 1. Compared with the method of installing the water inlet main line 1 and the water return main line 2 on the same side, more installation space can be saved. The channel cooling system is bottom-in and top-out as a whole. The water inlet main line 1 is at the bottom and the water return main line 2 is at the top. The temperature of the water inlet main line 1 is lower than that of the water return main line 2 to form a temperature difference. The hot water flows upward, and the cooling efficiency can be increased by utilizing natural convection, reducing losses, and having a better heat transfer effect. The first stop valve 32 on the water inlet branch line 3 and the second stop valve 41 on the water return branch line 42 of the water return branch line 4 are reserved on the same side of the channel equipment to facilitate docking with the high-temperature equipment cooling pipeline.

[0033] Since there are gas pipelines, natural gas and oxygen supply on both sides of the kiln, the requirements for ground insulation of the kiln are higher than those of the platinum channel. It is necessary to avoid the kiln electrode cooling water plate being electrified, which will cause the kiln as a whole, especially the steel structure, to be electrified, thereby affecting the gas pipeline. Therefore, the electrode cooling water plate cannot be electrified, and there are symmetrical electrode bricks on the left and right sides of the kiln. At the same time, in order to avoid the kiln electrode and platinum channel processes from affecting each other, the cooling water of the two processes is processed separately. The existing kiln industrial TV and hose water is taken from the kiln water pan with ultrapure water. The production process of platinum channel mainly relies on flanges and heating tiles for electric heating, without gas combustion assistance, and the requirements are lower than those of kilns. The heating flange and the platinum channel body are insulated from the earth due to refractory bricks and basically will not be connected. Under the same conditions, the platinum channel can use softened water, an intermediate product with a conductivity slightly higher than that of ultrapure water, while softened water cannot be used for kiln electrode cooling due to the above reasons. Based on the higher production standards and requirements of the substrate glass industry, kiln electrode cooling water uses ultrapure water with a conductivity of 0.1us / cm. Therefore, in order to save costs and facilitate the layout of the cooling water pipeline on the third floor, in this embodiment, the flange cooling water, industrial TV cooling water, and throat cooling water are connected to the channel together.

[0034] In this embodiment, 2-way water inlet branch pipes 3 are designed to cool the kiln throat, 3-way water inlet branch pipes 3 are used to cool the kiln industrial TV, 11-way water inlet branch pipes 3 are used to cool the platinum channel, and 6-way water inlet branch pipes 3 are used as spare water inlet pipes. The cooling water of the kiln industrial TV and throat is changed from ultrapure water taken from the kiln water tray to softened water taken from the channel water tray, so that the cooling of the kiln industrial TV and throat eliminates the pure water pretreatment, reverse osmosis, ion exchange and ultraviolet disinfection required for ultrapure water. Toxins and reverse osmosis membranes and ion exchange resins can be treated. Softened water can be obtained in the process of preparing pure water. The 6-way water inlet branch pipe 3 in front of the channel cooling water tray is reserved for the kiln industrial TV and throat. Calculated at 2 yuan / ton, the flow rate of the 6-way water inlet branch pipe 3 is 5.4m³ / h. Calculated at the cost of ultrapure water of 4.8 yuan / ton, it can save about 140,000 yuan a year, effectively reducing the working pressure and operating costs of pure water preparation equipment and extending the service life of the equipment.

[0035] In actual applications, the main water inlet line 1, the main water return line 2, the 22-way water inlet branch line 3, and the 22-way water return branch line 4 of the substrate glass channel cooling system are installed on the lower floor. At the same time, the water inlet branch line 3 and the water return branch line 4 extend from the lower floor to the upper floor by about 200 mm. The first stop valve 32 is installed at the outlet end of any water inlet branch line 3, and the second stop valve 41 is installed at the inlet end of any water return branch line 4. A section of the pipe is reserved at the outlet end of the first stop valve 32 for connecting with the cooling pipes of high-temperature equipment such as kiln industrial TV, kiln throat and platinum channel, and a section of the pipe is reserved at the inlet end of the second stop valve 41 for connecting with the cooling pipes of high-temperature equipment such as kiln industrial TV, kiln throat and platinum channel. Figure 7 As shown, a flange copper tube 52 for cooling water in and out is correspondingly provided on the outer periphery of any heating flange 51 on the platinum channel. The flange 51 is cooled by the cooling water flowing through the flange copper tube 52. The water inlet end of the flange copper tube 52 is connected to the pipeline reserved at the water outlet end of the corresponding first stop valve 32 through a hose and a pipe clamp. The water outlet end of the flange copper tube 52 is connected to the corresponding return branch pipe 42 through a hose and a pipe clamp. The hose clamp can be used to prevent the hose from falling off, and a pagoda head can be installed at the end of the pipe to achieve quick connection. In fact, the specific number of the water inlet branch pipe 3 and the water return branch pipe 4 can be determined according to the specific number of the heating flanges 51 on the platinum channel and the needs of the design of other equipment and spare groups.

[0036] The substrate glass channel cooling system of the present invention has a water inlet bypass pipe and a bypass water return pipe designed to maintain the stable operation of the substrate glass channel equipment and reduce process fluctuations. The instruments, devices and valves in various places in the pipeline are all connected by flexible joints, which is convenient for disassembly and replacement when the branch pipe is blocked, the instruments or valves are damaged, and the difficulty of maintenance after installation is reduced. At the same time, in daily maintenance, some pipelines can be prefabricated in advance for emergency use, which can respond quickly, replace quickly, reduce the failure time, speed up the resumption of production, and help maintain the stability of the process equipment and extend the service life of the platinum channel; the cooling water at the kiln industrial TV and the throat is connected to the channel cooling water system, so that the cooling water at the kiln industrial TV and the throat is changed from ultrapure water to softened water, which reduces the operating cost and the working pressure of the pure water preparation equipment, and helps to extend the service life of the equipment; the water inlet pressure transmitter, the water inlet temperature transmitter, the water outlet temperature meter with the transmitter, the water outlet flow meter, etc. are all connected to the remote controller for communication, and the corresponding process parameters can be remotely monitored in real time, and fluctuations or failures can be discovered and handled in time.

[0037] The above description is only a specific implementation of the present invention. It should be pointed out that any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
