Description

Technical Field

[0001] The utility model relates to the technical field of sulfuric acid leakage detection devices, in particular to a sulfuric acid leakage detection and blocking isolation device. Background Art

[0002] With the development of the chemical industry, sulfuric acid as an important chemical raw material is widely used in various fields. In the production and transportation of sulfuric acid, pipelines are usually used for transportation. With the long-term use of pipelines, the pipeline parts will age. The aged pipeline parts are prone to leakage. Once a leak occurs, it will not only pollute the environment, but also cause serious harm to personnel. At this time, in order to ensure the safety of pipeline transportation, corresponding leak detection and plugging isolation devices are usually installed on the pipeline to detect and isolate the leak in time.

[0003] However, most leak detection and plugging isolation devices can only detect and isolate leaks when in use. During pipeline transportation, after a leak occurs and isolating, there is still sulfuric acid in the pipeline at the leaking part. This part of sulfuric acid cannot be transported to other parts in time, which will cause inconvenience to the subsequent replacement of the leaking pipeline part. In view of this, we proposed a sulfuric acid leak detection and plugging isolation device. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 The utility model provides a technical solution: a sulfuric acid leakage detection and plugging isolation device, comprising a first electric valve 1 and a second electric valve 11 arranged on one side of the first electric valve 1, a first delivery pipe 10 is fixedly installed between the first electric valve 1 and the second electric valve 11, a second delivery pipe 12 is fixedly installed on the second electric valve 11, and a liquid pressure gauge 14 is arranged on the first delivery pipe 10 and the second delivery pipe 12, and the liquid pressure gauge 14 is used to detect the liquid pressure in the pipeline to determine whether there is a leakage;

[0027] Specifically, an electric control box 2 is provided on one side of the first delivery pipe 10, and a control module 20 is provided in the electric control box 2. A recovery box 3 is also provided on one side of the first delivery pipe 10, and a delivery pump 33 is provided on one side of the recovery box 3. An inflow pipe 36 is fixedly installed on the liquid outlet end of the delivery pump 33, and the inflow pipe 36 extends into the recovery box 3. A suction pipe 331 is fixedly installed on the liquid inlet end of the delivery pump 33, and a solenoid valve 34 is fixedly installed on the suction pipe 331. Multiple liquid inlet ends of the solenoid valve 34 are fixedly installed with outflow pipes 35, and the outflow pipes 35 are fixedly installed on the corresponding first delivery pipe 10 and second delivery pipe 12, so as to ensure that when in use, after the corresponding pipeline part leaks, the delivery pump 33 can be used to transport the sulfuric acid in the leaking pipeline part to the recovery box 3 for temporary storage operation.

[0028] In this embodiment, a threaded tube 13 is fixedly installed on the first delivery tube 10 and the second delivery tube 12, and the liquid pressure gauge 14 is threadedly connected to the threaded tube 13. The detection end of the liquid pressure gauge 14 extends into the corresponding tube body, which facilitates the assembly operation of the liquid pressure gauge 14.

[0029] Specifically, a sound and light alarm module 21 is fixedly installed on the top surface of the electric control box 2, and the sound and light alarm module 21 is used for alarm operation.

[0030] Furthermore, a threading hole 22 is provided on the bottom plate of the electric control box 2, and the threading hole 22 is used for threading operation; a cover plate 23 is hinged on the front side of the electric control box 2 through a hinge, and the cover plate 23 is used for dust protection operation when closed.

[0031] In addition, a top cover 30 is fixedly mounted on the top surface of the recovery box 3 , and the inflow pipe 36 passes through the top cover 30 , so that the top cover 30 is used for sealing operation.

[0032] It is worth noting that the recovery box 3 is provided with a transparent plate 31 arranged along the height direction of the recovery box 3, and the transparent plate 31 is used for observation operation.

[0033] In this embodiment, a discharge pipe 32 is fixedly installed on the bottom cylinder of the recovery box 3 , and a valve 321 is fixedly installed on the discharge pipe 32 to facilitate the discharge operation of sulfuric acid in the recovery box 3 .

[0034] It is worth noting that the liquid pressure gauge 14 is used to detect the liquid pressure in the pipeline and transmit the detection data to the control module 20. When the pipeline is not leaking, the liquid pressure in each pipeline is constant. If a pipeline leaks, the detection value of the liquid pressure gauge 14 at the corresponding pipeline position will decrease. At this time, the data signal is transmitted to the control module 20, and the control module 20 controls the electric valves on both sides of the unloading pipeline to close, realize the blocking and isolation operation, and suspend the continued delivery of sulfuric acid. At the same time, the control module 20 controls the solenoid valve 34 to open, and controls the delivery pump 33 to work, so as to realize the delivery of the residual sulfuric acid in the leaking pipeline to the recovery box 3 for temporary storage. At the same time, when a leak occurs, the control module 20 controls the sound and light alarm module 21 to emit a sound and light alarm.

[0035] Finally, it should be noted that the components involved in the utility model, such as the liquid pressure gauge 14, the control module 20, the first electric valve 1, the second electric valve 11, the delivery pump 33 and the sound and light alarm module 21, are all universal standard parts or components known to technical personnel in this field, and their structures and principles are all known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adapted controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the utility model. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0036] When the sulfuric acid leakage detection and plugging isolation device of the utility model is in use, after sulfuric acid is transported in the first delivery pipe 10 and the second delivery pipe 12, the liquid pressure gauge 14 detects the liquid pressure in the pipe. When the value detected by the liquid pressure gauge 14 at a certain position decreases, it proves that a leak occurs in the pipe position in front of the liquid pressure gauge 14. At this time, the first electric valve 1 and the second electric valve 11 at both ends of the leaking pipe position are closed to perform a plugging and isolation operation. In addition, the corresponding solenoid valve 34 channel is opened to connect the corresponding outflow pipe 35 to the leaking pipe, and then the delivery pump 33 is connected to an external power supply and made to work. The delivery pump 33 works to transport the sulfuric acid in the leaking pipe to the recovery box 3 for temporary storage, and then the valve 321 is opened to discharge the sulfuric acid in the recovery box 3 to the outside.
