Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, and in particular to an online cleaning device for clogging operating flame arresters. Background Technology

[0002] The styrene extraction unit operates under negative pressure. A liquid ring vacuum pump can be used to maintain the negative pressure state of the system. Each vacuum pump outlet is equipped with a flame arrester. During the operation of the vacuum pump, the flame arrester often becomes clogged, causing a drop in the system vacuum. Therefore, the flame arrester needs to be cleaned to prevent clogging.

[0003] Currently, cleaning clogged flame arresters is done manually. This involves using a vacuum pump to remove the flame arrester and cleaning the flame arrester mesh, which requires cleaning twice a month. This method involves opening hazardous medium pipelines and working at heights, potentially leading to accidental release of hazardous medium energy and human safety hazards. Furthermore, disassembling the flame arrester mesh causes pressure fluctuations in the negative pressure system, affecting its subsequent operation. Additionally, this method wastes manpower, materials, and resources. Utility Model Content

[0005] The online cleaning equipment for clogging flame arresters provided by this utility model includes: A pipeline network is installed inside the flame arrester, with an inlet pipeline connected to the upper end of the pipeline network and a discharge pipeline connected to the lower end of the pipeline network. The inlet pipeline and the discharge pipeline extend to the outside of the flame arrester. Several nozzles are installed on the pipeline network, with the nozzles of the nozzles facing the flame arrester network; The inlet pipeline is connected to a first pipeline, a second pipeline, and a third pipeline outside the flame arrester, and valves are installed on the first pipeline, the second pipeline, the third pipeline, and the discharge pipeline.

[0006] In one embodiment of this utility model, a high-point exhaust pipe is provided at the upper end of the flame arrester, penetrating both the inside and outside of the flame arrester.

[0007] In one embodiment of the present invention, a pressure gauge is provided inside the flame arrester, and the pressure gauge is used to monitor the pressure inside the flame arrester.

[0010] In one embodiment of the present invention, the pipeline network includes a main pipeline and secondary pipelines, and the main pipeline and the secondary pipelines are connected by connecting pipelines.

[0011] In one embodiment of this utility model, the secondary pipelines are in two groups, and the two groups of secondary pipelines are symmetrically distributed on both sides of the main pipeline.

[0012] In one embodiment of this utility model, the main pipeline and the secondary pipeline are distributed along the center of the flame arrester mesh.

[0013] In one embodiment of the present invention, a plurality of the nozzles are evenly distributed at intervals on the main pipeline and the secondary pipeline, wherein the length of the secondary pipeline is less than the length of the main pipeline.

[0014] In one embodiment of this utility model, the online cleaning equipment for clearing blockages in the operating flame arrester has two sets, and the two sets of the online cleaning equipment for clearing blockages in the operating flame arrester are arranged on both sides of the flame arrester mesh.

[0015] The beneficial effects of this utility model are as follows: The online cleaning equipment for clogging flame arresters proposed in this utility model, during use, firstly, opens the valve on the first pipeline, drawing residual oil into the pipeline network through the first pipeline and spraying it out through a nozzle aimed at the flame arrester network.

In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0022] The specific structure of the online cleaning equipment for clogging flame arresters in this utility model is described in conjunction with [reference needed]. Figure 1 and Figure 2 The online flame arrester blockage clearing equipment includes: A pipeline network 10 is installed inside the flame arrester. The upper end of the pipeline network 10 is connected to an inlet pipeline 14, and the lower end of the pipeline network 10 is connected to a discharge pipeline 15. The inlet pipeline 14 and the discharge pipeline 15 extend to the outside of the flame arrester. A plurality of nozzles 21 are disposed on the pipeline network 10, with the nozzles of the nozzles 21 facing the flame arrester network; The inlet pipeline 14 is connected to a first pipeline 17, a second pipeline 18, and a third pipeline 19 outside the flame arrester. Valves 20 are installed on the first pipeline 17, the second pipeline 18, the third pipeline 19, and the discharge pipeline 15.

[0023] Specifically, the pipeline network 10 is a mesh structure composed of several pipes, which facilitates the arrangement of nozzles. The overall structure of the pipeline network 10 is not limited and can be circular, rectangular, hexagonal, etc. The entire pipeline network 10 must be housed inside the flame arrester. Ideally, the mesh surface of the pipeline network 10 should be arranged parallel to the mesh surface of the flame arrester so that after the nozzles 21 are aligned with the flame arrester mesh, all nozzles 21 can simultaneously and evenly spray the flame arrester mesh. In addition, the pipeline network 10 can be composed of several pipes connected together or it can be a single integrated structure. The first pipeline 17, the second pipeline 18, the third pipeline 19, the inlet pipeline 14, and the outlet pipeline 15 can be integrated with the pipeline network 10 or connected through interfaces.

[0024] The online cleaning equipment for clogging flame arresters in this solution can be put into operation while the negative pressure system is running, i.e., after the flame arrester is switched online. The use of this cleaning equipment does not affect the operation of the process negative pressure system. Before using this cleaning equipment, all valves 20 should be closed. The operation procedure of this cleaning equipment is as follows: First, open valve 20 on the first pipeline 17 to cut out the clogged flame arrester. The residual oil is transported to the pipeline network 10 through the first pipeline 17 and sprayed out through nozzle 21. The nozzle 21 is pointed towards the flame arrester network, and the residual oil will be sprayed onto the flame arrester network. Open valve 22 and close it after the residual oil fills the flame arrester. After the residual oil has soaked into the flame arrester network and dissolved the blockage, open valve 20 on the discharge pipeline 15 to discharge the residual oil. Second, close valve 20 on the first pipeline 17 and open valve 20 on the second pipeline 18. Nitrogen gas is charged into the flame arrester through the second pipeline 18 for purging, which can pressurize and discharge the residual oil inside. Finally, close valve 20 of the second pipeline 18 and open valve 20 of the third pipeline 19. Steam is then introduced into the flame arrester through the third pipeline 19 to perform high-pressure purging of the flame arrester mesh. Condensed water will be discharged to the outside of the flame arrester through discharge pipeline 15. The cleaning equipment in this solution is installed on the flame arrester without altering its external dimensions or affecting its internal operation. Furthermore, cleaning the flame arrester does not require disassembly, reducing the safety hazards of fire, explosion, and falls from height associated with open pipelines and high-altitude operations.

[0025] In some embodiments, a high-point vent pipe 22 penetrating both the inside and outside of the flame arrester is provided at the upper end of the flame arrester. For example, Figure 1As shown, when residual oil is pumped into the flame arrester, the space inside the flame arrester can be sealed. Air in the space enters with the residual oil and can be discharged from the high-point exhaust pipe 22 to prevent the pressure inside the flame arrester from increasing.

[0026] In some embodiments, a pressure gauge is provided inside the flame arrester to monitor the internal pressure. For example, Figure 1 As shown, the pressure inside the flame arrester can be monitored in real time using a pressure gauge, so that the pressure inside the flame arrester can be adjusted in a timely manner to ensure that the pressure inside the flame arrester does not affect its use.

[0027] In some embodiments, the inlet pipeline 14 is provided with a four-way connector, which is used to connect the first pipeline 17, the second pipeline 18, and the third pipeline 19 respectively. Connecting the inlet pipeline 14 to the first pipeline 17, the second pipeline 18, and the third pipeline 19 via the four-way connector makes pipeline connection simple and quick.

[0028] In some embodiments, the discharge line 15 is connected to the underground tank 16. For example, Figure 1 As shown, the ground tank 16 can collect oil or liquid discharged from the flame arrester in a timely manner to prevent contamination.

[0029] In some embodiments, the pipeline network 10 includes a main pipeline 11 and secondary pipelines 12, which are connected by a connecting pipeline 13. For example, Figure 1 As shown, the main pipeline 11 and the secondary pipeline 12 facilitate the installation of the nozzles 21, allowing the nozzles 21 to be evenly distributed on one side of the flame arrester mesh, thus ensuring the cleaning effect on the flame arrester mesh.

[0030] In some embodiments, the secondary pipelines 12 are in two groups, and the two groups of secondary pipelines are symmetrically distributed on both sides of the main pipeline 11. For example, Figure 1 As shown, the arrangement of the secondary pipeline 12 facilitates the even distribution of the nozzles 21 and ensures a balanced cleaning force on the flame arrester mesh.

[0031] In some embodiments, the main pipeline 11 and the secondary pipeline 12 are distributed along the center of the flame arrester network. For example, Figure 1 As shown, this arrangement allows the nozzle 21 to clean the flame arrester mesh more effectively.

[0032] In some embodiments, a plurality of the nozzles 21 are evenly distributed at intervals on the main pipeline 11 and the secondary pipeline 12, wherein the length of the secondary pipeline 12 is shorter than the length of the main pipeline 11. For example, Figure 1 As shown, this arrangement enables the nozzles 21 to be evenly spaced, facilitating thorough and uniform cleaning of the flame arrester mesh.

[0033] In some embodiments, the online cleaning equipment for clogging the flame arrester has two sets, which are arranged on both sides of the flame arrester mesh. Simultaneous cleaning of the flame arrester mesh from both sides allows for rapid completion of the cleaning process, reducing the impact of the equipment's operation on the flame arrester's operation.

[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
