Description

Technical Field

[0001] The utility model relates to the technical field of acetylene production safety, in particular to an acetylene generating and purifying device which is convenient for maintenance. Background Art

[0002] In the process of producing acetylene gas by the calcium carbide method, part of the acetylene gas in the acetylene generator will directly enter the corresponding acetylene purification device, and the other part will first enter the acetylene gas tank for buffering and then be sent to the corresponding acetylene purification device.

[0003] In existing technology, multiple acetylene production lines, each consisting of the aforementioned acetylene generators and acetylene purification units, typically share a single acetylene gas tank. When one acetylene production line requires overhaul or individual shutdown for planned maintenance, the pipelines cannot be disconnected, forcing all of the lines to be shut down simultaneously. This severely impacts production efficiency and can result in incomplete gas replacement within the pipelines, posing a safety hazard. Utility Model Content

[0004] In order to solve the technical problem in the prior art that maintenance of acetylene production equipment affects production efficiency and poses safety hazards, the utility model provides an acetylene production equipment that is easy to maintain.

[0005] Acetylene production equipment that is easy to maintain includes multiple sets of acetylene generating devices, multiple sets of acetylene purification devices and acetylene gas holders. The gas outlets of the multiple acetylene generating devices and the gas inlets of the multiple acetylene purification devices are connected one-to-one through the acetylene gas holders. A first valve is provided between the acetylene gas holders and the gas inlets of the acetylene purification devices. The equipment also includes multiple sealing tanks, which are directly connected between the gas outlets of the acetylene generating devices and the gas inlets of the acetylene purification devices. A second valve is provided between the sealing tanks and the gas outlets of the acetylene generating devices.

[0006] The acetylene production equipment that is easy to maintain is characterized in that the sealing tank is sealed by a water seal.

[0007] The beneficial effects of the present invention include: the present invention is provided with a sealing tank, which can be used to isolate the acetylene purification device during the maintenance process, so that the acetylene purification device can be separately maintained, and it can be ensured that acetylene will not flow back during the maintenance process, thereby solving the technical problems in the prior art that the maintenance of acetylene production equipment will affect production efficiency and pose safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 This is a schematic diagram of the structure of the acetylene production equipment which is easy to maintain according to the utility model.

[0009] Marked in the figure are: 1-acetylene generator, 2-acetylene purification device, 3-acetylene gas holder, 4-first valve, 5-sealed tank, 6-second valve. DETAILED DESCRIPTION

[0010] The present invention will be described below with reference to the accompanying drawings.

[0011] like Figure 1 The figure shows an acetylene production equipment of the present invention that is easy to maintain, including multiple sets of acetylene generators 1, multiple sets of acetylene purification devices 2 and acetylene gas cabinets 3. The gas outlets of the multiple acetylene generators 1 and the gas inlets of the multiple acetylene purification devices 2 are connected one-to-one through the acetylene gas cabinets 3. The acetylene gas produced by the generator enters the acetylene gas cabinets 3 for buffering and then enters the purification device. A first valve 4 is provided between the acetylene gas cabinets 3 and the gas inlet of the acetylene purification device 2. The device also includes multiple sealing tanks 5, wherein the sealing tanks 5 are directly connected between the gas outlet of the acetylene generator 1 and the gas inlet of the acetylene purification device 2 without passing through the acetylene gas cabinets 3. A second valve 6 is provided between the sealing tanks 5 and the gas outlet of the acetylene generator 1.

[0012] Furthermore, the sealing method of the sealing tank 5 is water sealing, which has a simple and reliable structure and low cost.

[0013] In this embodiment, two sets of acetylene generators 1a and 1b and two corresponding sets of acetylene purification devices 2a and 2b are used. During normal production, the two sets of devices operate separately, and the water seal in the sealing tank 5 is not enabled. At this time, the sealing tank 5 only serves as part of the pipeline between the acetylene generator 1 and the acetylene purification device 2. Part of the acetylene gas in the acetylene generator 1 enters the acetylene purification device 2 through the sealing tank 5, and the remaining part enters the acetylene gas tank 3 for buffering, and then enters the acetylene purification device 2 for further processing. If the acetylene purification device 2a needs to be inspected and repaired, the second valve 6 of the sealing tank 5 of the corresponding production line and the first valve 4 of the acetylene purification device 2a are closed to replace the gas in the acetylene purification device 2a. After the replacement is completed, water is added to the sealing tank 5 to liquid-seal the air inlet pipe of the sealing tank 5, thereby realizing the inspection and repair of the acetylene purification device 2a alone. The acetylene generating device 1a, the acetylene generating device 2a and the acetylene purification device 2b are all operating normally. At the same time, the gas in the acetylene purification device 2a to be inspected can be prevented from entering the normally operating production equipment and causing safety hazards.

[0014] Compared with the existing technology, the acetylene production equipment of the present invention is easy to maintain. By additionally arranging a sealing tank between the acetylene generating device and the acetylene purification device, it is convenient to separately maintain the acetylene purification device while greatly reducing safety hazards. This solves the technical problem in the existing technology that maintenance of acetylene production equipment affects production efficiency and poses safety hazards.
