[0002] The existing gas-liquid separator is a separation device that uses the principles of centrifugal separation and wire mesh filtration to achieve liquid removal. It is mainly composed of a cylinder, a cyclone separator, a high-efficiency foam breaking net, a drain valve and other main components. It is generally installed in front of the drying device to achieve coarse filtration to remove part of the moisture in the air to reduce the workload of the drying device. After the existing gas-liquid separator has been working for a long time, the filter component inside it that is used to filter the moisture in the air has a high degree of humidity, and the moisture filtering effect will deteriorate. In order to ensure the water-gas separation effect, the gas-liquid separator is currently stopped and the filter component is removed for replacement. During the replacement process, the upstream and downstream equipment must also stop working, which affects the work efficiency and has poor production continuity. Utility Model Content

At this time, the corresponding box door can be opened to take out the filter component in the separation chamber switched to the idle state for replacement, thereby realizing the effect of simultaneous replacement and gas-liquid separation work, realizing continuous work, and thus improving work efficiency.

[0027] Example

[0028] Reference Figure 1-Figure 3 The present embodiment provides a gas-liquid separation device, including a box body 110, wherein two separation chambers 111 are arranged in the box body 110, and air outlets 112 are opened at the tops of the two separation chambers 111, and one side of the two separation chambers 111 is connected to a first air pipe 120, and the two first air pipes 120 are simultaneously connected to a three-way solenoid valve 130, and the three-way solenoid valve 130 is connected to a second air pipe 140, and a supporting frame 150 is arranged above the first air pipe 120 in the separation chamber 111, and a filter assembly 160 is arranged on the supporting frame 150, and the filter assembly 160 is used to filter moisture in water vapor, and two box doors 170 are arranged on the side walls of the box body 110, which are respectively close to the corresponding filter assemblies 160.

[0029] In this embodiment, when gas containing moisture is introduced through the second air pipe 140, one of the first air pipes 120 is connected through the three-way solenoid valve 130, so that the gas enters the corresponding separation chamber 111 through the first air pipe 120, and the moisture can be removed when the gas passes through the filter component 160 to form dry gas, and finally discharged from the corresponding air outlet 112, thereby realizing gas-liquid separation. At this time, the other separation chamber 111 is in an idle state. When the humidity of the filter component 160 in the separation chamber 111 in the running state is too high, the other first air pipe 120 is connected through the three-way solenoid valve 130 to switch the air path, so that the separation chamber 111 in the idle state enters the running state to continue the gas-liquid separation work, and the separation chamber 111 in the previous running state is switched to the idle state. At this time, the corresponding box door 170 can be opened to take out the filter component 160 in the separation chamber 111 switched to the idle state for replacement, thereby realizing the role of simultaneous replacement and gas-liquid separation, realizing continuous work, and thus improving work efficiency.

[0030] As an optional embodiment, the filter assembly 160 includes a mounting plate 161, which is placed on the supporting frame 150. A coarse filter layer 162 is arranged on the bottom surface of the mounting plate 161, and a plurality of filter tubes 163 connected to the coarse filter layer 162 are arranged on the top of the mounting plate 161. Fine filter elements 164 are arranged in the filter tubes 163. Both the coarse filter layer 162 and the fine filter element 164 are used to filter moisture in water vapor.

[0031] In this embodiment, when filtering, the gas first intercepts most of the moisture in the gas when passing through the coarse filter layer 162, and then passes through the fine filter elements 164 in multiple filter tubes 163 to filter the moisture in the gas again. Multiple fine filter elements 164 are set here for filtering, which can divide the gas into multiple strands for separate filtration, thereby increasing the contact area with the gas and improving the filtration efficiency.

[0032] It should be noted that when the entire filter assembly 160 is taken out for replacement, only the coarse filter layer 162 and the fine filter element 164 need to be replaced. Here, the coarse filter layer 162 can be connected to the ground of the mounting plate 161 by bonding or screws, and the fine filter element 164 can be directly inserted into the filter tube 163. The operation is convenient and quick.

[0033] As an optional embodiment, a gas channel 1641 is opened in the fine filter element 164, and the gas channel 1641 allows the gas to pass smoothly to avoid blockage and excessive gas pressure. The gas channel 1641 is wavy, which can increase the stroke of the gas in the gas channel 1641, thereby increasing the contact area between the fine filter element 164 and the gas to improve the filtering effect.

[0034] As an optional implementation, the vertical cross-sections of the mounting plate 161 and the coarse filter layer 162 are both in an upwardly arched arc shape, which can further increase the contact area between the coarse filter layer 162 and the gas to improve the filtering effect.

[0035] As an optional implementation, the filter tube 163 is integrally fixedly connected to the mounting plate 161, and the structure is firm and stable, which facilitates one-piece molding.

[0036] As an optional embodiment, a plurality of step holes 1611 are provided on the top of the mounting plate 161, and a limiting groove cooperating with the step holes 1611 is provided on the bottom of the filter tube 163. The cooperation between the step holes 1611 and the limiting groove allows the filter tube 163 to be detachably connected to the mounting plate 161. Since the material of the fine filter element 164 is relatively soft, it is slow to replace the fine filter elements 164 one by one. Therefore, based on the detachable structure of the filter tube 163 and the mounting plate 161, when replacement is performed, the filter tube 163 with the wet fine filter element 164 can be completely removed, and then the filter tube 163 with the dry fine filter element 164 can be replaced as a whole, so as to facilitate quick replacement, and then the filter assembly 160 can be put back to its original place, and then the wet fine filter element 164 in the removed filter tube 163 can be replaced for next use.

[0037] As an optional implementation, the three-way solenoid valve 130 is electrically connected to a PLC controller 180, which is disposed on the outer wall of the box body 110. The switching time can be set through the PLC controller 180, that is, after working for a period of time, the three-way solenoid valve 130 can be automatically switched to connect with another first air pipe 120 to switch the air path, thereby performing alternating filtering work, which has a high degree of automation and is easy to manage.

[0038] It should be noted that a buzzer electrically connected to the PLC controller 180 may be provided here. When the gas circuit is switched, the buzzer may sound to remind the staff that the filter assembly 160 should be replaced. The model of the PLC controller 180 may be S7-200.

[0039] As an optional embodiment, a drain solenoid valve 190 electrically connected to the PLC controller 180 is provided at the bottom of the separation chamber 111, and the drain solenoid valve 190 is connected to the first drain pipe 210, and the two first drain pipes 210 are simultaneously connected to the second drain pipe 220. After working for a period of time, a certain amount of water accumulates in the separation chamber 111. At this time, the drain solenoid valve 190 can be controlled to open by the PLC controller 180 to discharge the accumulated water through the first drain pipe 210 and the second drain pipe 220.

[0040] As an optional embodiment, a water level gauge 230 is provided on the inner wall of the separation chamber 111. The monitored water level of the water level gauge 230 is lower than that of the first air pipe 120. The water level gauge 230 is electrically connected to the PLC controller 180. The water level at the bottom of the separation chamber 111 can be monitored by the water level gauge 230. When the water level reaches a preset height, a signal can be sent to the PLC controller 180 to control the drain solenoid valve 190 to open for drainage. It does not require manual management and can operate automatically.

[0041] As an optional embodiment, the inner wall of the separation chamber 111 is provided with a guide plate 240 located below the supporting frame 150. The guide plate 240 is arranged at an angle and faces the first air pipe 120. The guide plate 240 is used to guide the airflow to the filter assembly 160 above. There is a gap between the downwardly inclined end of the guide plate 240 and the side wall of the box body 110 having the first air pipe 120.

[0042] In this embodiment, when the gas enters the separation chamber 111 from the first gas pipe 120, it first collides with the guide plate 240 to guide the gas so that it can quickly flow upward through the filter assembly 160, while also improving the uniformity of contact between the gas and the filter assembly 160. In addition, the water filtered on the filter assembly 160 can drip onto the guide plate 240, and finally drip onto the bottom of the separation chamber 111 along the downward tilt direction of the guide plate 240.

[0043] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
