Description

Technical Field

[0001] The present disclosure relates to the technical field of glass furnaces, and in particular to a heat storage chamber and a photovoltaic glass furnace. Background Art

[0002] In the production of photovoltaic glass, environmental protection indicators are very strict, and the kiln process parameters are required to operate stably. Therefore, a heat storage chamber inspection door is needed that can be opened for daily inspection and maintenance without affecting the emission of flue gas indicators, while also ensuring the stable and controlled operation of the kiln process.

[0003] Chinese patent document CN101907298A discloses a method for thermally repairing the small furnace tongue crown of a coal-fired glass furnace. The coal-fired glass furnace burner primarily comprises an air regenerator, a gas regenerator, and a small furnace structure. A thermal repair door is provided on the rear wall of the regenerator. At the start of the thermal repair, the explosion-proof fire tube is ignited, the upper grid of the gas regenerator is removed, and after the gas regenerator is sealed from below, the upper thermal repair door of the air regenerator is removed, the axial flow fan is activated, and cooling water drains are connected through the upper thermal repair door. When the regenerator temperature drops, the cracked small furnace tongue crown is removed and a new one is built. The present invention utilizes a manual cold repair method, accessed through the thermal repair door on the rear wall of the small furnace, and by lowering the temperature of the manual operation space, a damaged tongue crown is fundamentally replaced, resolving the problem of thermally repaired material gradually flaking and washing away in the prior art. In the above-mentioned comparative documents, a thermal repair door is provided on the heat storage chamber. The thermal repair door is built with insulating bricks and needs to be removed during thermal repair. The removal process is not only cumbersome, but also cannot effectively adjust the degree of opening of the thermal repair door. This is not only costly but also inconvenient for controlling flue gas emissions. In addition, after the maintenance is completed, the maintenance port needs to be resealed, further increasing the maintenance cost of the heat storage chamber. Utility Model Content

[0032] Techniques, methods, and equipment known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the techniques, methods, and equipment should be considered part of the specification.

[0033] In order to solve the problem of high maintenance cost and inconvenience of the heat storage chamber, according to the embodiment of the present application, a heat storage chamber is provided. The heat storage chamber of the present application will be described in detail below with reference to the accompanying drawings.

[0034] Referring to Figures 1 to 2 According to the embodiment of the present application, a heat storage chamber is provided. The heat storage chamber includes a main body 11, an access door 2, and a driving assembly 3.

[0035] The main body 11 includes a cavity inside, and an access opening 111 is provided on the side wall of the main body 11 and communicates with the cavity; the access door 2 is movably arranged on the main body 11 to adjust the opening size of the access opening 111; the driving assembly 3 is connected with the access door 2 to drive the access door 2 to move.

[0036] In the present application, the main body 11 internally comprises a cavity for the passage of combustion-supporting gas or exhaust gas. The main body 11 is provided with an access opening 111 in communication with the cavity, which is used for daily inspection and maintenance of the regenerative chamber 1. The access door 2 is movably arranged on the main body 11 to adjust the opening size of the access opening 111, so that the insulation layer and the insulation bricks do not need to be removed during the inspection of the regenerative chamber 1, thereby reducing the cost of the inspection process. By driving the access door 2 to move using the driving assembly 3, during the inspection process, the opening and closing size of the access door 2 is adjusted according to the real-time monitoring of the relevant data in the kiln, thereby ensuring that the emission of flue gas indicators is not affected during the daily inspection and maintenance of the regenerative chamber 1, and at the same time, the photovoltaic glass kiln process can be stably operated.

[0037] Specifically, when the dust in the photovoltaic glass kiln reaches a certain degree, daily maintenance is required, and when cleaning is required, the worker can enter the regenerative chamber 1 through the access opening 111 on the regenerative chamber 1 to perform the cleaning work. By arranging the access door 2 at the access opening 111, the opening size of the access opening 111 exposed by the access door 2 can be precisely controlled by controlling the driving assembly 3, so that the access door 2 is from closed to completely opened, and in this process, the corresponding small furnace combustion-supporting air consumption is adjusted in real time according to the opening and closing of the access door 2, the total combustion-supporting air consumption in the cavity is kept stable (i.e. the pressure in the furnace is stable), and the flue gas emission index is stably controlled. That is, by arranging the access door 2 driven by the driving assembly 3 at the access opening 111, the working steps of removing the insulation bricks and the insulation layer arranged at the access opening 111 in the prior art are reduced, and the work efficiency is improved. In addition, the inspection cost of the regenerative chamber 1 is reduced, and the controllability of the entire inspection process is realized.

[0038] That is, by using the above-mentioned regenerative chamber 1, the inspection cost is reduced during the daily inspection of the regenerative chamber 1, the inspection process is precisely controlled, and the process is stably operated during the inspection process.

[0039] In some embodiments, the access door 2 needs to consider high-temperature resistance, corrosion resistance, etc. when selected, for example, the access door 2 can be a stainless steel door, an alloy door, a graphite door, a ceramic door, etc., and the specific selection of the present application is not specifically limited.

[0040] In some embodiments, as Figure 1As shown, the driving assembly 3 comprises a driving member 31 and a transmission member 32. The transmission member 32 is arranged between the driving member 31 and the access door 2, and when the driving member 31 drives the transmission member 32 to move, the access door 2 is driven to move, thereby adjusting the opening size of the access opening 111. In the present application, the opening and closing size of the access door 2 directly affects the pressure in the kiln, and when the pressure in the kiln changes greatly, the opening and closing size of the access door 2 is finely adjusted to stabilize the pressure in the kiln, reduce the fluctuation of the kiln process during the maintenance process, and ensure the stable operation of the photovoltaic glass kiln process, thereby improving the quality of the photovoltaic glass.

[0041] In some embodiments, the driving member 31 comprises a motor, and the transmission member 32 comprises a lead screw or a gear rack. In the process of controlling the opening and closing of the access door 2, in order to ensure the stable and controlled operation of the photovoltaic glass kiln process, the opening and closing size of the access door 2 needs to be accurately controlled, and the motor is selected for driving to achieve accurate speed control. In addition, in order to ensure that the access door 2 adjusts the opening of the access opening 111, the access door 2 moves linearly, and therefore the transmission member 32 that can convert the rotation of the motor into linear motion is selected, for example, the transmission member 32 can be any one of a lead screw or a gear rack. In the present application, the transmission member 32 is a lead screw, which has the advantages of high precision, low friction, high load capacity, and various installation methods, and can improve the stability of the movement of the access door 2 and achieve accurate control.

[0042] In some embodiments, the regenerator 1 is provided with a guide rail 4, and the guide rail 4 supports and fixes the access door 2. The guide rail 4 extends to the access opening 111, so that the access door 2 can fully cover the access opening 111. When the access door 2 is slidably arranged on the guide rail 4, the opening size of the access opening 111 can be accurately adjusted according to the actual maintenance situation. Through the online control system, the access door 2 is accurately controlled, and the operation process of the access door 2 can be stopped or started at any time, thereby ensuring the stable operation of the pressure in the kiln.

[0043] In some embodiments, as shown in the figure, Figure 1 The guide rail 4 comprises a first I-steel 41, a second I-steel 42, a first channel steel 43, and a second channel steel 44. The first I-steel 41, the second I-steel 42, the first channel steel 43, and the second channel steel 44 are fixedly combined to form a guide rail 4 frame, so that the access door 2 can smoothly slide at the access opening 111. Specifically, the first channel steel 43 and the second channel steel 44 are arranged in parallel and extend to the access opening 111, the first I-steel 41 is vertically connected to the first ends of the first channel steel 43 and the second channel steel 44 corresponding to each other, the second I-steel 42 is vertically connected to the second ends of the first channel steel 43 and the second channel steel 44 corresponding to each other, and the access door 2 is slidably arranged between the first channel steel 43 and the second channel steel 44.

[0044] Specifically, the use of I-beams and channel steels in combination can enhance the structural stability of the guide rail 4. The I-beams can provide higher bending strength, and the channel steels can increase the connection points due to their open parts, making it convenient to connect with other structural parts, thereby improving the overall stability and rigidity. At the same time, the combination of channel steels and I-beams makes the channel steels easy to process and install, and the use of welding or bolting the channel steels and I-beams improves construction efficiency. In addition, the seismic resistance is good. The use of I-beams and channel steels can effectively divide and absorb energy, improve the seismic resistance of the guide rail 4, ensure that the drive assembly 3 reduces vibration during the process of driving the inspection door 2, improve the driving efficiency, and thus achieve precise control of the opening size of the inspection port 111 of the inspection door 2. In other words, the use of I-beams and channel steels in combination can not only give full play to their respective advantages, but also make up for the shortcomings that may exist in each other, making the final guide rail 4 both economical and practical, while improving the safety and durability of the guide rail 4.

[0045] In some embodiments, as Figure 2 As shown, a sealing layer 8 is provided between the surface of the inspection door 2 facing away from and toward the heat storage chamber 1 and the groove wall of the first channel steel 43, as well as between the surface of the inspection door 2 facing away from and toward the heat storage chamber 1 and the groove wall of the second channel steel 44. The sealing layer 8 is provided between the inspection door 2 and the channel steel. When no maintenance is being performed, the inspection door 2 seals the inspection opening 111. Specifically, the top of the inspection door 2 contacts the roller 5 in the first channel steel 43, and the two side walls of the inspection door 2 close to the first channel steel 43 are respectively provided with a sealing layer 8 between the first channel steel 43. When the heat storage chamber 1 is not being maintained, the inspection opening 111 can be better sealed to improve the quality of the product. At the same time, the bottom of the inspection door 2 contacts the roller 5 in the second channel steel 44, and the two side walls of the inspection door 2 close to the second channel steel 44 are respectively provided with a sealing layer 8 between the second channel steel 44. That is, when the regenerator 1 requires inspection and maintenance, a sealing layer 8 is provided between the inspection door 2 and the channel steel. However, the inspection door 2 can be slightly adjusted in position, allowing it to be slightly disengaged during sliding. When the inspection door 2 moves to the predetermined position, it returns to its original position within the channel steel. This arrangement ensures that the sealing layer 8 does not hinder the sliding of the inspection door 2 when it is necessary, and provides a good seal for the inspection opening 111 when the regenerator 1 does not require inspection.

[0046] In some embodiments, the sealing layer 8 needs to be made of a material that can withstand high temperature (temperature higher than 300℃), has good sealing performance and is durable. For example, the sealing layer 8 can be made of ceramic fiber, graphite-based sealing material, refractory mortar, metal sealing gasket, etc., which are not specifically limited in the present application, and can be reasonably selected according to the working temperature, pressure condition, chemical environment and installation and maintenance convenience in actual production. In addition, the sealing layer 8 arranged between the channel steel and the access door 2 can also bring the following beneficial effects: good sealing can effectively reduce the heat dissipation, maintain the temperature stability in the kiln, and improve the energy utilization efficiency; ensure the cleanliness in the kiln, ensure the product quality of photovoltaic glass; help maintain the pressure balance in the kiln, avoid the pressure change caused by the entry of external air or the discharge of internal gas, affect the production process; ensure the safety of the operators and help prevent safety accidents such as fire; reduce the influence of the external environment on the conditions in the furnace, thereby reducing the aging speed of the internal parts of the equipment and prolonging the service life of the equipment.

[0047] In some embodiments, the first channel steel 43 and the second channel steel 44 are both provided with a rolling part, which is beneficial to the opening and closing of the access door 2.

[0048] Specifically, the rolling part includes a plurality of rolling shafts 5 arranged at intervals, for example, the number of rolling shafts 5 can be 2, 5, 10, 20, etc., and the specific number is not specifically limited in the present application and can be set as needed in actual production. The rolling shafts 5 in the channel steel can significantly reduce the frictional resistance of the access door 2 during opening or closing, making the operation of the access door 2 more smooth, which is particularly important for the frequent maintenance and maintenance of the regenerative chamber 1, and can also improve the work efficiency. Second, the rolling shafts 5 can help the access door 2 better fit the sealing layer 8 and ensure the sealing effect. Third, reduce the maintenance cost, reduce the wear degree between the access door 2 and the channel steel, and reduce the long-term operation cost. Fourth, improve the operation precision, the rolling shafts 5 can accurately control the position of the access door 2, and can accurately control the opening and closing size of the access door 2 during the maintenance process.

[0049] In some embodiments, the heat storage chamber 1 further comprises a sensor (not shown in the figure) and a controller 6, the sensor is electrically connected with the controller 6, and the controller 6 is connected with the driving assembly 3; the sensor transmits the received signal to the controller 6, and the controller 6 controls the driving assembly 3 to drive the maintenance door 2 to move. In this application, the pressure in the kiln is controlled by a computer, specifically, by a DCS. When the heat storage chamber 1 needs to be maintained and repaired, the pressure in the corresponding kiln on the computer is adjusted, the signal is transmitted to the sensor, the sensor transmits the signal of the change of the pressure to the controller 6, the controller 6 controls the driving assembly 3 to drive the maintenance door 2 to move, the DCS system can monitor the pressure in the kiln in real time, according to the opening size of the maintenance opening 111 of the maintenance door 2, the amount of combustion-supporting air in the heat storage chamber 1 is adjusted in time, so that the amount of air entering through the maintenance opening 111 and the intake amount of the combustion-supporting air keep the pressure in the kiln balanced. When the pressure in the kiln is balanced, it also ensures that the smoke emission index can be stably controlled.

[0050] According to the above embodiments, it can be known that the heat storage chamber 1 of the present application comprises a main body 11, a maintenance door 2 and a driving assembly 3. The heat storage chamber 1 solves the problem that the heat storage chamber 1 cannot stop working at any time during daily maintenance and repair; and effectively shortens the action time, reduces the work intensity and improves the work efficiency; in addition, it also realizes accurate control of the air intake amount during maintenance and daily maintenance, keeps the pressure in the photovoltaic glass kiln stable; and can further solve the stable operation of the process parameters and the smoke emission index during the kiln reversing process and the maintenance and repair process.

[0051] In some embodiments, in combination Figures 1 to 3 The present application also provides a photovoltaic glass kiln, which comprises the above-mentioned heat storage chamber 1. In the process of producing photovoltaic glass, the kiln needs to be reversed once after working for 20 minutes, to ensure that the temperature distribution in the furnace is uniform, reduce local overheating, improve the utilization efficiency of energy, improve product quality, reduce thermal stress, and optimize the process flow.

[0052] As Figure 3 shown, in the photovoltaic glass kiln, the heat storage chambers 1 are symmetrically arranged on both sides of the melting pool 7, and the symmetrically arranged heat storage chambers 1 are also symmetrically provided with maintenance doors 2. The two heat storage chambers 1 perform different work, one of them introduces combustion-supporting air (i.e. fresh air enters the heat storage chamber 1 after preheating and then enters the combustion chamber), and the other discharges the flue gas after combustion (the high-temperature flue gas releases heat before being discharged through the heat storage chamber 1, which can realize effective recovery and utilization of energy), and when discharging the flue gas, it is linked with the desulfurization and denitrification system, and whether the smoke emission index meets the standard is monitored in real time.

[0053] Specifically, when the kiln needs to be reversed after working for a period of time (i.e. 20 minutes), the kiln reversal is precisely controlled through the DCS, at which time the air inlet and the exhaust gas also follow the automatic reversal. The original regenerator 1 for inlet of combustion-supporting air is replaced by the exhaust gas, and the regenerator 1 for exhaust gas is used for inlet of combustion-supporting air. In actual production, when the regenerator 1 needs to be cleaned, the work is carried out in the regenerator 1 for inlet of combustion-supporting air to ensure the safety of the workers. When reversal is needed, the workers immediately exit the regenerator 1, at which time the sensor transmits a signal to the controller 6, which controls the driving assembly 3 to timely close the access door 2. At this time, when the access door 2 is from fully open to fully closed, the opening of the rotary gate (not shown in the figure) on the DCS needs to be unchanged, and the combustion-supporting air consumption of the corresponding small furnace is simultaneously increased to stabilize the pressure of the kiln. After reversal, when the original regenerator 1 for exhaust gas also needs to be cleaned, the DCS can be used to synchronously open the access door 2 thereof, which is conducive to the cleaning of the workers.

[0054] In summary, in the present application, by providing two regenerators 1 on the photovoltaic glass kiln, the effective recovery and utilization of energy are achieved. In addition, by providing the access door 2 at the access opening 111, the opening and closing of the access door 2 can be precisely controlled through the DCS during the daily maintenance and maintenance of the regenerator 1, and the amount of air entering the regenerator 1 can be timely adjusted by adjusting the opening and closing size of the access door 2, so as to realize the overall stability of the air entering the regenerator 1, thereby ensuring the controlled operation of the flue gas emission index.
