Description

Technical Field

[0001] The utility model belongs to the technical field of gas-liquid separation equipment, and specifically relates to a drainage control device for a horizontal gas-water separator. Background Art

[0002] Magnetic levitation turbine vacuum pumps are widely used in papermaking, electricity, chemical industry, food, pharmaceutical and other fields because of their advantages of energy saving, oil-free and water-free, and low noise. Their working principle is that through the high-speed rotation of the impeller, the wet air is sucked into the impeller and pressurized at high speed. After the single-stage turbine vacuum pump is pressurized by one impeller, it is discharged from the diffuser and volute. The multi-stage turbine vacuum pump is gradually compressed by multiple impellers to produce a higher vacuum degree. The horizontal gas-water separator is a filtering device used in high-speed magnetic levitation turbine vacuum pumps.

[0003] In the Chinese invention patent with patent application number 202311295479.1, a horizontal gas-water separator is proposed. The patent has the following problems: due to the deficiencies in the drainage device of the separator, when the internal medium of the separator is complex, various problems are likely to occur during the gas-liquid separation process, resulting in poor drainage of the gas-water separator and even affecting the normal operation of the magnetic levitation turbine vacuum pump. Utility Model Content

[0004] The main technical problem to be solved by the utility model is to provide a drainage control device for a horizontal gas-water separator, which adopts a structure for efficient drainage control through liquid level height change detection, and realizes interlocking control with a magnetic levitation turbine vacuum pump to ensure the normal operation of the magnetic levitation turbine vacuum pump.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A drainage control device for a horizontal gas-water separator comprises a tee, the water inlet end of the tee is fixedly mounted on the water outlet pipe of the separator, a first filtrate pump and a second filtrate pump are respectively mounted on the two water outlet ends of the tee, a liquid level detection assembly is arranged inside the separator, the first filtrate pump and the second filtrate pump are both connected to the liquid level detection assembly, and the liquid level detection assembly is also connected to a magnetically suspended turbine vacuum pump.

[0007] The following is a further optimization of the above technical solution by the utility model:

[0008] The liquid level detection assembly comprises a low liquid level gauge, a high liquid level gauge and a safety liquid level gauge which are arranged in sequence from bottom to top, and the low liquid level gauge, the high liquid level gauge and the safety liquid level gauge are all installed inside the separator.

[0009] Further optimization: the low liquid level gauge, high liquid level gauge and safety liquid level gauge all adopt float level gauges.

[0010] Further optimization: the low liquid level gauge, high liquid level gauge and safety liquid level gauge are all connected to the first filtrate pump, the high liquid level gauge and safety liquid level gauge are all connected to the second filtrate pump, and the safety liquid level gauge is connected to the magnetic levitation turbine vacuum pump.

[0011] Further optimization: the first filtrate pump is connected to a first remote local switch, and the second filtrate pump is connected to a second remote local switch.

[0012] The utility model adopts the above technical solution, which has the following beneficial effects: the technical solution of the utility model is ingenious in conception and reasonable in structure, and the liquid level height of the liquid inside the separator is monitored in real time through the liquid level detection component, so as to control the start and stop of the first filtrate pump and the second filtrate pump according to the change of the liquid level height, so as to discharge the liquid in the separator efficiently and conveniently.

[0013] Furthermore, the utility model does not change the structure of the separator, but only installs a liquid level detection component in the separator and installs a first filtrate pump and a second filtrate pump at the outlet pipe, thereby achieving the purpose of low-cost automatic drainage.

[0014] The liquid level detection component includes a low liquid level gauge, a high liquid level gauge and a safety liquid level gauge. The safety liquid level gauge is used to detect the critical value of the liquid level in the separator. When the liquid level is higher than the safety level, it is easy to affect the drainage of the magnetic levitation turbine vacuum pump. Therefore, the magnetic levitation turbine vacuum pump alarms and shuts down at this time, thereby realizing interlocking control between the horizontal gas-water separator and the magnetic levitation turbine vacuum pump.

[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] like Figure 1-Figure 4 As shown together, a drainage control device for a horizontal gas-water separator includes a tee pipe 1, the water inlet end of the tee pipe 1 is fixedly installed on the water outlet pipe of the separator 2, the two water outlet ends of the tee pipe 1 are respectively installed with a first filtrate pump 3 and a second filtrate pump 4, a liquid level detection component 5 is arranged inside the separator 2, the first filtrate pump 3 and the second filtrate pump 4 are both connected to the liquid level detection component 5, and the liquid level detection component 5 is also connected to a magnetically levitated turbine vacuum pump 6.

[0022] In this embodiment, the first filtrate pump 3 and the second filtrate pump 4 are both commercially available filtrate pumps that can be controlled manually or automatically.

[0023] In this embodiment, the liquid level detection component 5 is used to monitor the liquid level inside the separator 2 in real time, and control the start and stop of the first filtrate pump 3 and the second filtrate pump 4 through the detected liquid level height change data to realize the drainage function of the separator 2.

[0024] Among them, the liquid level detection component 5 includes a low liquid level gauge 51, a high liquid level gauge 52 and a safety liquid level gauge 53 arranged in sequence from bottom to top, and the low liquid level gauge 51, the high liquid level gauge 52 and the safety liquid level gauge 53 are all installed inside the separator 2.

[0025] The low liquid level gauge 51, the high liquid level gauge 52 and the safety liquid level gauge 53 are all float level gauges.

[0026] In this embodiment, since the float level meter has high fault tolerance, simple logic control and high reliability, it can efficiently complete the drainage control work when the medium inside the separator 2 is complex, thereby effectively improving the drainage control effect of the utility model.

[0027] like Figure 3 As shown, the low liquid level gauge 51, the high liquid level gauge 52 and the safety liquid level gauge 53 are all connected to the first filtrate pump 3, the high liquid level gauge 52 and the safety liquid level gauge 53 are all connected to the second filtrate pump 4, and the safety liquid level gauge 53 is connected to the magnetic levitation turbine vacuum pump 6.

[0028] In this embodiment, the low liquid level gauge 51, the high liquid level gauge 52 and the safety liquid level gauge 53 are provided to realize the drainage function by efficiently controlling the start and stop of the first filtrate pump 3 and the second filtrate pump 4 according to the change of the liquid level height of the internal liquid on the separator 2.

[0029] The utility model can judge whether the operation of the first filtrate pump 3, the second filtrate pump 4 and the separator 2 is normal according to the continuous change of the liquid level height.

[0030] At the same time, the magnetic levitation turbine vacuum pump 6 is interlocked with the magnetic levitation turbine vacuum pump 6. When the separator 2 cannot drain water normally, the magnetic levitation turbine vacuum pump 6 is promptly controlled to stop, thereby avoiding damage to the magnetic levitation turbine vacuum pump 6.

[0031] In addition, the first filtrate pump 3 is connected to a first remote local switch 7 , and the second filtrate pump 4 is connected to a second remote local switch 8 .

[0032] In this embodiment, the first remote local switch 7 and the second remote local switch 8 both use intermediate relays.

[0033] The first remote local switch 7 is used to switch the first filtrate pump 3 to a manual-automatic mode, and the second remote local switch 8 is used to switch the second filtrate pump 4 to a manual-automatic mode.

[0034] When the first filtrate pump 3 and the second filtrate pump 4 are switched to the automatic mode, the utility model can perform efficient automatic drainage control according to the change of the liquid level height.

[0035] When the first filtrate pump 3 and the second filtrate pump 4 are switched to manual mode, the operator can start and stop the first filtrate pump 3 and the second filtrate pump 4 according to the actual liquid level height changes, which is not only used to realize the drainage function, but also can be used for the maintenance work of the first filtrate pump 3, the second filtrate pump 4 and the separator 2.

[0036] like Figure 4 As shown, the drainage control logic of the utility model is as follows:

[0037] In the first step, when the low liquid level gauge 51 detects that the liquid level inside the separator 2 reaches the low liquid level height, the low liquid level gauge 51 is turned on to control the first filtrate pump 3 to start drainage.

[0038] In the second step, if the low liquid level gauge 51 detects that the liquid level inside the separator 2 is lower than the low liquid level height, it means that the drainage is completed. At this time, the low liquid level gauge 51 is disconnected and the first filtrate pump 3 is controlled to stop running after a delay of 15 seconds;

[0039] If the high liquid level gauge 52 detects that the liquid level inside the separator 2 has reached the high liquid level, it means that the drainage is not completed. At this time, the high liquid level gauge 52 is turned on to control the second filtrate pump 4 to start drainage.

[0040] In the third step, if the high liquid level gauge 52 detects that the liquid level inside the separator 2 is lower than the high liquid level, it means that the drainage is completed, and the high liquid level gauge 52 is disconnected, and the first filtrate pump 3 and the second filtrate pump 4 are controlled to stop running after a delay of 60 seconds;

[0041] If the safety liquid level gauge 53 detects that the liquid level inside the separator 2 reaches the safety liquid level height, it means that the drainage is not completed, the safety liquid level gauge 53 is turned on, the magnetic suspension turbine vacuum pump 6 is controlled to stop, and an alarm is issued.

[0042] At this time, it is prompted to check whether the first filtrate pump 3, the second filtrate pump 4 and the separator 2 are normal.

[0043] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
