Description

Technical Field

[0001] The present invention relates to the technical field of gas processing equipment, and in particular to a gas drying device, a maintenance system and a method. Background Art

[0002] In modern glass production lines, it is crucial to ensure the continuity and stability of compressed air supply, as this is directly related to the smoothness of the production process and the quality of the product. In order to achieve this goal, installing double valves in front of the micro-heat regeneration dryer has become a common and effective measure in the industry. This design is designed to continue to maintain the supply of compressed air through the valve on the other side even if there is a problem with the valve on one side, thereby minimizing the risk of production interruption caused by air outage.

[0003] However, as the glass manufacturing industry accelerates its overall transformation towards intelligence, more and more links in the production line have achieved automated control and remote monitoring, which has greatly improved production efficiency and reduced labor costs. But at the same time, it has also brought some new challenges. Specifically, as the frequency of manual on-site inspections has been greatly reduced, the ability to instantly perceive and respond to the operating status of equipment has become a new test.

[0004] In this context, when a micro-heat regeneration dryer or its related systems fail and require remote intervention by operators, a potential problem becomes apparent: the inability to quickly and accurately determine and operate the dual valve status on site often results in the failure to close the front valve synchronously while the dryer is shut down remotely. This delay may not only cause further disturbances in the compressed air system and affect the stable operation of the production line, but also violate the original intention of improving the overall intelligence level and achieving efficient unmanned management. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a gas drying device, comprising:

[0006] A micro-heat regeneration dryer, wherein the air inlet of the micro-heat regeneration dryer is connected to the air inlet pipeline of the glass production line through an electric ball valve, and the air outlet of the micro-heat regeneration dryer is connected to the air outlet pipeline of the glass production line;

[0007] The opening and closing state of the electric ball valve is consistent with the working state of the micro-heat regeneration dryer.

[0008] Preferably, a pre-oil remover is provided between the air intake pipe and the electric ball valve.

[0009] Preferably, the pre-oil remover comprises an oil remover body, and a drain outlet of the oil remover body is provided with a ball valve and an automatic drain valve which are connected in sequence.

[0010] Preferably, a dust collector is provided between the air outlet and the air outlet duct.

[0011] Preferably, a stop valve is also provided on the air intake pipe.

[0012] The present invention also provides a maintenance system for a gas drying device, comprising a maintenance module, which is electrically connected to the micro-heat regeneration dryer and the electric ball valve in the gas drying device as described above, and is used to control the micro-heat regeneration dryer to operate and the electric ball valve to open when no maintenance instruction is received remotely from an operator, and to control the micro-heat regeneration dryer to stop and the electric ball valve to close when a maintenance instruction is received remotely from an operator.

[0013] The present invention also provides a maintenance method for a gas drying device, which is applied to the above maintenance system, and includes the maintenance system determining whether a maintenance instruction sent remotely by an operator is received:

[0014] If yes, the micro-heat regeneration dryer is controlled to stop and the electric ball valve is controlled to close;

[0015] If not, the micro-heat regeneration dryer is controlled to operate and the electric ball valve is controlled to open.

[0016] The above technical solution has the following advantages or beneficial effects:

[0017] An electric ball valve is added in front of the micro-heat regeneration dryer, which opens and closes synchronously with the micro-heat regeneration dryer. When the equipment is shut down for maintenance, the operator remotely controls the micro-heat regeneration dryer and the electric valve to close automatically synchronously, ensuring that the valve in front of the micro-heat regeneration dryer is closed in time, so that the main gas delivery will not be affected during equipment maintenance, achieving the purpose of intelligentization of the entire plant.

[0019] Figure 2 The figure is a schematic structural diagram of a maintenance system for a gas drying device in a preferred embodiment of the present invention. DETAILED DESCRIPTION

[0020] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment, and other embodiments may also fall within the scope of the present invention as long as they conform to the gist of the present invention.

[0021] In a preferred embodiment of the present invention, based on the above problems existing in the prior art, a gas drying device is provided. Figure 1 As shown, including:

[0022] A micro-heat regeneration dryer 1, the air inlet of the micro-heat regeneration dryer 1 is connected to the air inlet pipe 3 of the glass production line through an electric ball valve 2, and the air outlet of the micro-heat regeneration dryer 1 is connected to the air outlet pipe 4 of the glass production line;

[0023] The opening and closing state of the electric ball valve 2 is consistent with the working state of the micro-heat regeneration dryer 1.

[0024] Furthermore, in this embodiment, a pre-oil remover 5 is provided between the air intake pipe 3 and the electric ball valve 2 .

[0025] Furthermore, in this embodiment, the pre-oil remover 5 comprises an oil remover body 51, and the drain port of the oil remover body 51 is provided with a ball valve 52 and an automatic drain valve 53 which are connected in sequence.

[0026] Furthermore, in this embodiment, a dust collector 6 is provided between the air outlet and the air outlet pipe 4, and a ball valve 52 is provided between the dust collector 6 and the air outlet pipe 4.

[0027] In a preferred embodiment of the present invention, a stop valve 7 is further provided on the air intake pipe 3 .

[0028] Specifically, in this embodiment, the opening and closing state of the electric ball valve 2 is linked and synchronized with the working state of the micro-heat regeneration dryer 1; the electric ball valve 2 can act as a cut-off valve, and the operator can remotely control it, and it meets the conventional piping method. The double valve can ensure that the main pipe does not affect the compressed air delivery when the equipment is repaired. After adding the electric ball valve 2, the water in the pipeline can be drained by the automatic drain valve 53 of the pre-oil remover 5, and there is no need to add an additional drain valve at the lowest point of the pipeline.

[0029] The stop valve 7 and the electric ball valve 2 between the pre-degreaser 5 and the micro-heat regeneration dryer 1 are all in the normally open state. When the micro-heat regeneration dryer 1 starts to operate normally, the electric ball valve 2 is fully opened. Open the stop valve 7, and ordinary compressed air enters the pre-degreaser 5 for degreasing. At this time, the ball valve 52 and the automatic drain valve 53 of the pre-degreaser body 51 can be used to discharge the sewage in the pipeline. Then, the purified compressed air without oil and water is sent out through the electric ball valve 2, the micro-heat regeneration dryer 1, the post-dust collector 6, and the ball valve 52 in sequence.

[0030] If the micro-heat regeneration dryer 1 needs to be repaired, the operator remotely sends a repair command to shut down the micro-heat regeneration dryer 1. Since the electric ball valve 2 is interlocked with it, it is also automatically closed. The stop valve 7 can be normally opened to avoid compressed air leakage in the main pipe. The residual sewage in the pipeline can be discharged using the ball valve 52 and automatic drain valve 53 provided in the front oil remover body 51.

[0031] The present invention also provides a maintenance system for a gas drying device, such as Figure 2As shown, the maintenance module 200 is included, and the maintenance module 200 is electrically connected to the micro-thermal regeneration dryer 1 and the electric ball valve 2 in the gas drying device 100 as mentioned above, and is used to control the micro-thermal regeneration dryer 1 to operate and control the electric ball valve 2 to open when no maintenance instruction is received remotely from the operator, and to control the micro-thermal regeneration dryer 1 to stop and control the electric ball valve 2 to close when a maintenance instruction is received remotely from the operator.

[0032] Specifically, in this embodiment, when an equipment failure occurs and the operator remotely shuts down the micro-heat regeneration dryer 1, the electric ball valve 2 is closed synchronously, ensuring that the valve in front of the micro-heat regeneration dryer 1 is closed in time, achieving the purpose of intelligentization of the entire plant, facilitating maintenance, saving materials and costs.

[0033] The present invention also provides a maintenance method for a gas drying device, which is applied to the above maintenance system, and includes the maintenance system determining whether a maintenance instruction sent remotely by an operator is received:

[0034] If yes, the micro-heat regeneration dryer is controlled to stop and the electric ball valve is controlled to close;

[0035] If not, the micro-heat regeneration dryer is controlled to run and the electric ball valve is controlled to open.

[0036] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of this specification and illustrations should be included in the protection scope of the present invention.
