Description

Technical Field

[0001] This invention belongs to the technical field of gas testing equipment, and specifically relates to an environmentally friendly intelligent gas processing device and control system. Background Technology

[0002] With the development of power systems, SF6 equipment (GIS, GIL, SF6 circuit breakers, etc.) is increasingly being used in power systems. SF6 gas testing is a routine pre-test for these power equipment. SF6 gas is widely used in electrical insulation equipment due to its excellent insulation properties and arc-extinguishing ability. However, for a long time, the exhaust gas generated by SF6 testing has been indiscriminately released into the atmosphere, causing enormous environmental damage over time. In addition, in field SF6 gas testing, the gas sampling ports are spaced far apart, but the testing equipment is bulky and inconvenient to move. Multiple tools (adapters, wrenches, SF6 gas leak detectors) also need to be carried, resulting in low efficiency and the easy loss of tools. Summary of the Invention

[0003] To address the aforementioned issues, this invention combines low-carbon technology with solutions to problems on the production site, effectively recovering exhaust gas generated during SF6 gas testing and improving the work efficiency of on-site testing personnel.

[0004] To overcome the problems existing in the prior art, the present invention provides the following technical solution:

[0005] Environmentally friendly intelligent gas treatment devices include:

[0006] The recycling vehicle includes a frame, on which an upper platform and a lower platform are sequentially mounted. The upper platform holds testing instruments, and the lower platform holds an exhaust gas recovery box.

[0007] The exhaust gas recovery box is connected to the test instrument via an exhaust pipe.

[0008] The exhaust gas recovery box is equipped with a first gas filter, a second gas filter, and a recovery gas tank, which are connected in sequence through an exhaust pipe.

[0009] Furthermore, the upper platform is provided with a first storage slot and a second storage slot, the first storage slot being a circular groove and the second storage slot being a square groove.

[0010] Furthermore, the side of the frame is provided with a lifting handrail, and a shift gear is installed at the connection between the lifting handrail and the frame and the upper platform. The shift gear engages with the locking teeth on the side of the frame.

[0011] Furthermore, wheels are installed at the bottom of the lower platform, and a side rail is installed on the edge of the upper platform. A side rail bracket is provided on the side rail, and the side rail bracket is inserted into the upper platform.

[0012] Furthermore, a hinge is installed between the frame and the side of the upper platform, and a hinge is installed between the frame and the side of the lower platform. The two short sides of the upper and lower platforms are hinged to the frame and configured to rotate upwards. Both the upper and lower platforms can be folded downwards symmetrically along the central axis.

[0013] Furthermore, the first gas filtration device is equipped with a filter plate, and the second gas filtration device is equipped with a molecular sieve.

[0014] Furthermore, a first buffer air bag is connected before the first air filtration device, and a second buffer air bag is connected before the second air filtration device.

[0015] Furthermore, a first solenoid valve, a low-pressure check valve, and a first pressure sensor are sequentially installed on the exhaust pipe connected to the first buffer gas bag inside the exhaust gas recovery box. A low-pressure air pump, a second solenoid valve, and a second pressure sensor are sequentially installed on the exhaust pipe between the first air filter and the second buffer gas bag. A compressor, a high-pressure check valve, and a pressure gauge are sequentially installed on the exhaust pipe between the second air filter and the recovery gas tank.

[0016] An environmentally friendly intelligent gas treatment control system is used to control the environmentally friendly intelligent gas treatment device described above. It includes: a control module installed inside a tail gas recovery box; the control module receives processing commands and controls the operation of a first solenoid valve and a second solenoid valve; the control module is connected to a serial communication module, which enables communication between the control module and external devices.

[0017] Furthermore, when the first pressure sensor or the second pressure sensor exceeds the set threshold, the control module issues an alarm signal and transmits it through the serial communication module.

[0018] The beneficial effects of this invention are:

[0019] 1. This invention designs a tail gas recovery and treatment device based on low-carbon technology requirements. The tail gas generated during the experiment reaches a secondary buffer device through a normally closed solenoid valve. When the pressure reaches a certain value, the gas pump is activated to compress the gas into a storage tank for storage. The device is also designed with power failure protection, leakage protection, and overpressure indication. It can effectively recover the tail gas generated during SF6 gas experiments, preventing the direct emission of greenhouse gases into the air.

[0020] 2. The entire device structure was specifically designed to address the unique characteristics of on-site SF6 gas testing. The upper layer is designed with placement positions for the equipment required for on-site testing (SF6 gas comprehensive detector, adapter connectors, SF6 gas leak detector, wrenches), and the bottom is equipped with casters for easy movement around the testing site. The overall design features a modular, foldable structure. This structural design facilitates the handling of testing equipment and the carrying of tools, reducing the workload of testing personnel and improving their work efficiency on-site.

[0021] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures pointed out in the description and the drawings. Attached Figure Description

[0031] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0032] like Figure 1 In this embodiment, the environmentally friendly intelligent gas treatment device includes a recycling vehicle 1. The recycling vehicle 1 includes a frame 15, on which an upper platform 11 and a lower platform 12 are sequentially mounted. Testing instruments 2 are placed on the upper platform 11, and an exhaust gas recovery box 3 is placed on the lower platform 12. The testing instruments 2 are connected to the exhaust gas recovery box 3 via an exhaust pipe. The testing instruments 2 include an SF6 electrical equipment gas comprehensive detector, an SF6 gas leak detector, etc. The exhaust gas recovery box 3 recovers the exhaust gas generated during the test and purifies the SF6 exhaust gas through adsorption and filtration for reuse.

[0033] like Figure 2 The upper platform 11 is provided with a first storage slot 111 and a second storage slot 112. The first storage slot 111 is a circular groove, and the second storage slot 112 is a square groove. The first storage slot 111 and the second storage slot 112 are used to place various test tools, connectors, etc.

[0034] The frame 15 is provided with a lifting armrest 13 on its side. A shift gear 14 is installed at the connection between the lifting armrest 13 and the frame 15 and the upper platform 11. The shift gear 14 engages with the locking teeth on the side of the frame 15. The height of the lifting armrest 13 can be adjusted by rotating the shift gear 14, allowing the lifting armrest 13 to be rotated upwards or rotated downwards to unfold.

[0035] The lower platform 12 is equipped with wheels 16 at its bottom, and the upper platform 11 is equipped with side rails 17 along its edge. The side rails 17 are provided with side rail brackets, which are inserted into the upper platform 11. The wheels 16 at the bottom facilitate movement within the test area.

[0036] A hinge 18 is installed between the frame 15 and the side of the upper platform 11, and a hinge 18 is installed between the frame 15 and the side of the lower platform 12. The two short sides of the upper platform 11 and the lower platform 12 are hinged to the frame 15 and configured to rotate upwards. Both the upper platform 11 and the lower platform 12 can be folded downwards symmetrically along the central axis. The entire recovery vehicle 1 is foldable. When the test is over and the instruments are removed, the folded state is such that the middle position of the upper platform 11 and the lower platform 12 is facing upwards, and the vehicle is symmetrically folded up along the central axis. The two short sides of the upper platform 11 and the lower platform 12 are hinged to the frame 15 and rotated upwards to a near-vertical position, so that the entire length of the recovery vehicle 1 can be folded up. In the unfolded state, the middle position of the upper platform 11 and the lower platform 12 is pressed down until it is horizontal. The two short sides of the upper platform 11 and the lower platform 12 are hinged to the frame 15 and rotated downwards to a horizontal position. The upper platform 11 and the lower platform 12 are restricted to folding upwards only from the middle position. Once unfolded to the horizontal direction, they cannot be rotated anymore to ensure that the test instruments are placed stably.

[0037] like Figure 3 The exhaust gas recovery box 3 is equipped with a first gas filter 33, a second gas filter 35, and a recovery gas tank 4, which are connected in sequence through an exhaust pipe. The first gas filter 33 contains a filter plate, and the second gas filter 35 contains a molecular sieve. A first buffer gas bag 32 is connected before the first gas filter 33, and a second buffer gas bag 34 is connected before the second gas filter 35. The filter plate is designed to filter particulate matter and decomposition products in the exhaust gas, and the molecular sieve removes moisture from the SF6 gas. The purified gas then enters the compressor 47, is compressed by the compressor 47, and is stored in the recovery gas tank 4.

[0038] The exhaust gas recovery box 3 is equipped with a first solenoid valve 41, a low-pressure check valve 42, and a first pressure sensor 43 sequentially installed on the exhaust pipe connected to the first buffer air bag 32. The exhaust pipe between the first air filter device 33 and the second buffer air bag 34 is equipped with a low-pressure air pump 44, a second solenoid valve 45, and a second pressure sensor 46 sequentially installed on the exhaust pipe between the second air filter device 35 and the recovery gas tank 4. The exhaust pipe between the second air filter device 35 and the recovery gas tank 4 is equipped with a compressor 47, a high-pressure check valve 48, and a pressure gauge 49 sequentially installed on the exhaust pipe.

[0039] This embodiment also provides an environmentally friendly intelligent gas treatment control system for controlling an environmentally friendly intelligent gas treatment device. The system includes a control module 31 installed within the exhaust gas recovery box 3. The control module 31 receives processing commands and controls the operation of the first solenoid valve 41 and the second solenoid valve 45. The control module 31 is connected to a serial communication module, which enables communication between the control module and external devices. When the first pressure sensor 43 or the second pressure sensor 46 exceeds a set threshold, the control module 31 issues an alarm signal and transmits it through the serial communication module.

[0040] Furthermore, in field operations, traditional SF6 gas testing requires approximately 2 man-hours per GIS interval for each SF6 test. (hours), the total working hours after using this device is 1 (person) The working hours have been greatly shortened, reducing the investment of manpower and resources in the work and thoroughly implementing the concept of reducing the burden on security personnel.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
