As shown in fig. 1, the invention provides an annealing furnace waste heat utilization system of a photovoltaic rolled glass production line, which comprises an annealing furnace and a glass tempering furnace, wherein a hot air interface 1 of the annealing furnace is connected with a hot air conveying pipeline 2 for conveying residual hot gas to the glass tempering furnace, the hot air conveying pipeline 2 is connected with an air supply device 3, an exhaust pipeline 4 for discharging the residual hot gas to the outside is connected between the air supply device 3 and the hot air interface 1 of the annealing furnace, and an exhaust regulating valve 5 is arranged on the exhaust pipeline 4; the glass tempering furnace is also additionally provided with a discharge pipeline for discharging gas to the outside.
In the annealing furnace waste heat utilization system of the photovoltaic rolled glass production line, the waste heat gas flow generated by the annealing furnace is conveyed to the glass tempering furnace through the hot air conveying pipeline 2, the waste heat gas flow has higher temperature and can heat the glass in the glass tempering furnace, so that the waste heat gas flow in the annealing furnace can be utilized, the utilization rate of energy is improved, and the energy waste is reduced.
The heating section of the glass tempering furnace can be divided into a low-temperature heating section and a high-temperature heating section, air flows between the low-temperature heating section and the high-temperature heating section are mutually isolated, and the hot air conveying pipeline 2 is connected with the low-temperature heating section of the glass tempering furnace. The low-temperature heating section adopts a hot air and electric heating combined mode, the low-temperature heating section is provided with an electric heating device, the low-temperature heating section can heat the photovoltaic rolled glass to about 300 ℃, and the high-temperature heating section adopts a complete electric heating mode and can heat the glass to the softening point temperature. For convenience of description, the glass tempering furnace 10 referred to hereinafter is referred to as a low-temperature heating section of the glass tempering furnace.
In the annealing furnace waste heat utilization system of the photovoltaic rolled glass production line, as shown in fig. 1, the annealing furnace is divided into a plurality of sections A, B, C along the glass movement direction, each section is provided with a hot air interface 1, and each hot air interface 1 is connected with a path of hot air conveying pipeline 2; the glass tempering furnace 10 is divided into a plurality of areas along the moving direction F of glass, and each hot air conveying pipeline 2 conveys residual hot air to one area of the glass tempering furnace 10. The temperatures of the residual heat gas in different sections of the annealing furnace have certain difference, and different hot air interfaces 1 of the annealing furnace are connected with different areas of the glass tempering furnace 10 according to the temperatures required by different areas of the glass tempering furnace 10.
As shown in fig. 1, the annealing kiln section includes an upstream area a, a midstream area B and a downstream area C, hot air interfaces 1 of the A, B, C areas are connected with a hot air conveying pipeline 2, each hot air conveying pipeline 2 is connected with an air supply device 3, different hot air conveying pipelines 2 are connected to different areas of the glass tempering furnace 10, and the air supply devices 3 provide power for air flows in the hot air conveying pipelines 2. Because the residual heat gas output by the annealing kiln has higher temperature, the air supply device 3 needs to be capable of enduring high temperature, as a preferred embodiment, the air supply device 3 is a high-temperature fan capable of frequency conversion adjustment, and the working temperature is less than or equal to 500 ℃.
In order to make the air flow input into the glass tempering furnace 10 by the hot air delivery pipe 2 uniform, as shown in fig. 1, a top branch pipe 6 and a bottom branch pipe 7 are arranged at the downstream end of the hot air delivery pipe 2, and the top branch pipe 6 and the bottom branch pipe 7 are respectively connected to the top and the bottom of the glass tempering furnace 10. Thus, the top and bottom of the glass tempering furnace 10 can receive hot gas at the same time, and the temperature in the glass tempering furnace 10 is relatively balanced. In order to conveniently adjust the flow rate of the hot gas in the glass tempering furnace 10, as shown in fig. 1, the top branch pipe 6 and the bottom branch pipe 7 are respectively provided with a branch adjusting valve 8, so that the flow rate of the hot air entering the glass tempering furnace 10 can be conveniently adjusted through the branch adjusting valve 8, and the purpose of adjusting the temperature in the glass tempering furnace 10 is achieved.
In order to ensure that the waste heat gas input into the glass tempering furnace 10 can fully exchange heat with the glass in the glass tempering furnace 10 and improve the heat exchange efficiency, a countercurrent heating mode is adopted in the glass tempering furnace 10. As shown in FIG. 1, the arrow direction F in the glass tempering furnace 10 in FIG. 1 indicates the moving direction of the glass. Since the temperature of the glass is higher upstream of the lehr than downstream, the hot residual gas temperature in the upstream section a of the lehr is higher than the hot residual gas temperature in the downstream section C. Since the temperature of the glass in the downstream of the glass tempering furnace 10 is higher than that in the upstream, the hot residual gas in the upstream section A of the annealing furnace is fed to the downstream of the glass tempering furnace 10, the hot residual gas in the midstream section B of the annealing furnace is fed to the midstream of the glass tempering furnace 10, and the hot residual gas in the downstream section C of the annealing furnace is fed to the upstream of the glass tempering furnace 10. The discharge duct of the glass tempering furnace 10 is provided at the upstream end of the glass tempering furnace 10, so that in the glass tempering furnace 10, the flow direction of hot air is opposite to the glass movement direction, and the temperature of hot air is gradually reduced but still higher than the glass temperature in the corresponding region in the process of flowing upstream from downstream, thereby heat exchange with glass can be carried out in the whole flowing process, and the heat exchange efficiency is improved. As shown in FIG. 1, the discharge piping of the glass tempering furnace 10 includes a top discharge pipe 11 provided at the top of the glass tempering furnace 10 and a bottom discharge pipe 12 provided at the bottom of the glass tempering furnace 10, and the outlets of the top discharge pipe 11 and the bottom discharge pipe 12 are combined together to discharge the gas to the outside.
In order to facilitate the adjustment of the residual heat gas flow rate fed into the glass tempering furnace 10, as shown in fig. 1, a gas supply adjusting valve 9 is provided on the hot air conveying pipeline 2 between the exhaust pipeline 4 and the air supply device 3, and the gas supply adjusting valve 9 can be adjusted according to the gas flow rate required by the glass tempering furnace 10. In order to facilitate detection of parameters such as temperature, pressure, flow and the like of gas in the hot air conveying pipeline 2, as shown in fig. 1, a section of the hot air conveying pipeline 2 from the annealing kiln hot air interface 1 to the exhaust pipeline 4 is a first section of the hot air conveying pipeline, and a temperature detection device 13 and a pressure detection device 14 are arranged on the first section of the hot air conveying pipeline; one section of hot air conveying pipeline 2 from the exhaust pipeline 4 to the top branch pipe 6 and the bottom branch pipe 7 is a second section of hot air conveying pipeline, and a temperature detection device 13, a pressure detection device 14 and a flow detection device 15 are arranged on the second section of hot air conveying pipeline, so that gas parameters output by the annealing kiln hot air interface 1 and gas parameters input into the glass tempering furnace 10 can be detected so as to be convenient for control.
In order to control the gas flow in the hot air conveying pipeline 2 conveniently, the air supply devices 3 on each hot air conveying pipeline 2 are high-temperature fans, the working temperature of each high-temperature fan is less than or equal to 500 ℃, the frequency conversion adjustment is carried out, and the working frequency is set manually and is in linkage with the pressure signal of the pressure detection device 14 on the corresponding hot air conveying pipeline 2 correspondingly. The air supply regulating valves 9 on the hot air conveying pipelines 2 are all high-temperature automatic cut-off butterfly valves, and the switching states of the butterfly valves are respectively interlocked with the running states of the air supply devices 3 on the corresponding hot air conveying pipelines 2. When the air supply device 3 stops running, the air supply regulating valve 9 is automatically closed; when the air supply device 3 is started to operate, the air supply adjusting valve 9 is automatically opened.
As shown in fig. 1, the exhaust regulating valves 5 on the exhaust pipes 4 are also high-temperature automatic regulating butterfly valves, and the opening degrees of the exhaust regulating valves 5 are linked with temperature signals detected by the temperature detecting devices 13 on the first-stage hot air conveying pipe and the second-stage hot air conveying pipe. During normal production, the exhaust regulating valve 5 is in a closed state according to a certain pressure value fed back by the pressure detection device 14 on the first section of hot air conveying pipeline and a temperature feedback signal fed back by the temperature detection device 13 on the first section of hot air conveying pipeline, and all hot air in each area of the annealing kiln is sent to the glass tempering furnace 10 through the air supply devices 3 for heating the photovoltaic rolled glass. When the hot air discharge amount of a certain area of the annealing kiln is increased due to production adjustment, the hot air discharge amount of the area is larger than the air supply amount of the air supply device 3, the opening degree of the exhaust adjusting valve 5 on the exhaust pipeline 4 of the area is correspondingly increased according to the increase condition of the pressure detection value detected by the pressure detection device 14 on the first section of the hot air conveying pipeline, and redundant hot air is discharged to the outside atmosphere. When the hot air discharge amount of a certain area of the annealing kiln is reduced due to production adjustment, the hot air discharge amount of the area is smaller than the air supply amount of the air supply device 3, the pressure detection value detected by the pressure detection device 14 on the first section of the hot air conveying pipeline of the area is smaller than a certain initial pressure value, at the moment, the exhaust regulating valve 5 on the exhaust pipeline 4 of the area keeps a closed state, and the corresponding air supply device 3 in the area correspondingly reduces the operation frequency according to the pressure detection value until the pressure detection value on the first section of the hot air conveying pipeline of the area is restored to the certain initial pressure value. Meanwhile, the glass tempering furnace 10 correspondingly increases the electric heating load according to the reduction of the flow of the hot air, so as to ensure that the photovoltaic rolled glass in the glass tempering furnace 10 is heated to a set temperature. When the hot air discharge temperature of a certain area of the annealing kiln is increased due to production adjustment, the hot air temperature at the downstream of the air supply device 3 of the area is higher than a certain initial set temperature value, at the moment, the exhaust regulating valve 5 on the exhaust pipeline 4 of the area is correspondingly increased in opening degree according to the increase of the temperature detection value detected by the temperature detection device 13 at the downstream of the air supply device 3, and outdoor cold air is sucked into the air supply device 3 until the hot air temperature at the downstream of the air supply device 3 is recovered to a certain initial set value. When the hot air discharge temperature is reduced due to production adjustment in a certain area of the annealing kiln, the hot air temperature at the downstream of the air supply device 3 in the area is lower than a certain initial set temperature value, the exhaust regulating valve 5 on the exhaust pipeline 4 is kept closed at the moment, and the electric heating load is correspondingly increased according to the reduction of the hot air temperature by the glass toughening furnace 10 so as to ensure that the photovoltaic rolled glass is heated to the set temperature. As shown in fig. 1, the branch regulating valve 8 is a manual high-temperature butterfly valve, and the flow rates of the hot air at the upper part and the lower part can be manually regulated to regulate the temperatures of the upper space and the lower space in the glass tempering furnace 10.
Based on the technical scheme, the annealing furnace waste heat utilization system of the photovoltaic rolled glass production line can fully utilize waste heat airflow of the annealing furnace and reduce energy waste.
