Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of petrochemical industry, and relates to an efficient antifoaming agent injection system for a lubricating oil production line. Background Art
[0002] During the production and transportation of lubricating oil, due to a certain amount of additives contained in the lubricating oil, the oil inevitably collides and vibrates in the pipeline, which will cause the oil to have a tendency to generate foam. The formation of stable foam will cause extremely adverse consequences, not only resulting in waste and loss of lubricating oil, but also reducing the performance of the oil. Therefore, the foam generated in the pipeline must be eliminated in time. In production practice, generally, a compound antifoaming agent is injected into the lubricating oil pipeline for defoaming treatment. The antifoaming agent is an oil-soluble surfactant, which can increase the surface tension of the oil foam or reduce the strength and toughness of the foam surface film, thereby reducing the ability of the lubricating oil to generate foam and achieving the purpose of eliminating foam.
[0003] The addition of traditional antifoaming agents is simply to directly add the antifoaming agent into the lubricating oil pipeline by a feed pipe. The antifoaming agent cannot be fully contacted with the lubricating oil, and the antifoaming effect is not good. Moreover, when the oil pressure in the pipeline is relatively high, it will cause difficulties in adding the antifoaming agent, which brings certain troubles to the production of lubricating oil. Content of the Utility Model
[0004] The utility model provides an efficient antifoaming agent injection system for a lubricating oil production line, aiming to add an antifoaming agent to the lubricating oil production line to make the antifoaming agent fully contact with the lubricating oil.
[0005] For this reason, the utility model adopts the following technical solutions:
[0006] An efficient antifoaming agent injection system for a lubricating oil production line includes multiple lubricating oil pipelines and a stirrer for stirring the antifoaming agent. The outlet at the lower end of the stirrer is connected with a main feed pipe for transporting the antifoaming agent; a main pipe valve and a feed pump are arranged on the main feed pipe; the outlet of the main feed pipe is connected with a number of parallel feed branch pipes, and a filter and a branch pipe valve are arranged on each feed branch pipe;
[0007] The tail end of each feed branch pipe is connected with a spray head, and each spray head is respectively placed in different lubricating oil pipelines, and the spraying direction of the spray head is the same as the liquid flow direction of the lubricating oil pipeline; a spray head installation port is arranged on the lubricating oil pipeline, and the spray head is placed in the lubricating oil pipeline through the spray head installation port and is fixed and sealed with the spray head installation port through a flange;
[0008] The spray head is conical, including a cone cap and a ring plate. The head of the cone cap faces the opposite direction of the lubricating oil flow; the ring plate is densely provided with spray holes.
[0009] Furthermore, the feed pump is a metering pump.
[0010] Furthermore, the branch pipe valve is a check valve.
[0011] Furthermore, the nozzle is located on the central axis of the lubricating oil pipeline.
[0012] The beneficial effects of the present utility model are as follows:
[0013] 1. The anti-foaming agent can be evenly added to the lubricating oil pipeline and make full contact with the lubricating oil, and the anti-foaming effect is ideal; when the oil pressure in the lubricating oil pipeline is relatively high, the lubricating oil will not flow back into the anti-foaming agent filling system, ensuring the safe operation of the system; the system is easy to control, and the filling flow rate of the anti-foaming agent and whether the anti-foaming agent is added to each lubricating oil pipeline can be flexibly controlled;
[0014] 2. The conical cap of the nozzle faces the opposite direction of the lubricating oil flow. When the lubricating oil flows through the conical cap, a low-pressure area is formed behind the conical cap. Therefore, the lubricating oil behind the conical cap forms a turbulent state. The ring of the nozzle is located behind the conical cap, and the anti-foaming agent ejected from the ring holes of the ring contacts the lubricating oil in the turbulent state, enabling the anti-foaming agent to make full and uniform contact with the lubricating oil, ensuring the anti-foaming effect and avoiding the problem of uneven mixing caused by direct addition through the feeding pipe.

[0018] The following further illustrates the present utility model in conjunction with the drawings and specific embodiments:
[0019] As Figure 1 and 2As shown in the figure, an efficient antifoaming agent filling system for a lubricating oil production line includes multiple lubricating oil pipelines 9 and a stirrer 1 for stirring the antifoaming agent. The outlet at the lower end of the stirrer 1 is connected to a main feed pipe 2, and the main feed pipe 2 is used to transport the antifoaming agent; a main pipe valve 4 and a feed pump 5 are provided on the main feed pipe 2; the outlet of the main feed pipe 2 is connected to a number of parallel feed branch pipes 3, and a filter 6 and a branch pipe valve 7 are provided on each feed branch pipe 3. The tail end of each feed branch pipe 3 is connected to a spray head 8, and each spray head 8 is respectively placed in a different lubricating oil pipeline 9, and the spraying direction of the spray head 8 is the same as the liquid flow direction of the lubricating oil pipeline 9; a spray head installation port is provided on the lubricating oil pipeline 9, and the spray head 8 is placed in the lubricating oil pipeline 9 through the spray head installation port and fixed and sealed with the spray head installation port through a flange 11; the spray head 8 is conical, including a cone cap and an annular plate, and the orientation of the head of the cone cap is opposite to the lubricating oil flow direction; the annular plate is also in a concave conical shape, and spray holes are densely distributed on the annular plate, and the spray head 8 is located on the central axis of the lubricating oil pipeline 9. In the present invention, the feed pump 5 is a metering pump, and the branch pipe valve 7 is a check valve.
[0020] The working principle of the present invention is as follows:
[0021] During use, various antifoaming agents are added to the stirrer 1 for stirring to obtain a composite antifoaming agent with better effects, and then the mixed antifoaming agent is transported to each feed branch pipe 3 through the main feed pipe 2 and injected into the lubricating oil pipeline 9 by the spray head 8. In particular, since the orientation of the cone cap of the spray head 8 is opposite to the lubricating oil flow direction, when the lubricating oil flows through the cone cap, a low-pressure area is formed behind the cone cap, so the lubricating oil behind the cone cap forms a turbulent state. And the annular plate of the spray head 8 is located behind the cone cap, and the antifoaming agent ejected from the spray holes of the annular plate contacts the turbulent lubricating oil, enabling the antifoaming agent to be in full and uniform contact with the lubricating oil, ensuring the antifoaming effect and avoiding the problem of uneven mixing caused by direct addition through the injection pipe.
[0022] In addition, during the transportation of the antifoaming agent, foaming may also occur due to the bending of the pipeline. The filter 6 is provided to eliminate the foam generated during the transportation of the antifoaming agent and ensure the uniform ejection of the antifoaming agent. Selecting a metering pump as the feed pump 5 can better control the flow rate of the antifoaming agent; the branch pipe valve 7 is selected as a check valve to prevent the lubricating oil from flowing into the antifoaming agent filling system when the oil pressure in the lubricating oil pipeline 9 is relatively high, thus ensuring the safe operation of the system.
