This form cannot effectively distribute the gas, and after a period of use, a layer of oil is suspended inside the water seal device. If a flame enters retrograde, it is easy to generate a flame on the water surface, which poses a certain safety hazard. Therefore, it is necessary to remove the floating oil.

Detailed ways

The present application is further described in detail below in conjunction with the accompanying drawings.

In order to more clearly understand the technical solutions presented in the embodiments of the present application, the working principle of the existing combustible gas discharge water seal device for petrochemical engineering is first introduced.

The existing petrochemical engineering combustible gas discharge water seal structure is a vertical or horizontal tank. After the sealing water is poured inside, the air inlet pipe is buried below the liquid level. The existing water seal structure has a fixed internal structure and the water level cannot be adjusted. Water needs to be added or pumped when skimming the oil. In this process, the water level fluctuates greatly, which will cause fluctuations in the discharged gas, and pulse combustion is prone to occur, which poses certain safety hazards. Therefore, the existing system needs to be improved to improve its adaptability and oil discharge convenience due to its single application form and poor subsequent flexibility.

Please refer to Figure 1, which is a combustible gas discharge water seal device for petrochemical engineering disclosed in an embodiment of the present application, including: a connecting box 1, an air inlet pipe 2, a partition A3, a ventilation hole 4, a partition B5, an air outlet pipe 6, a drain pipe A7, a liquid inlet pipe 8, a drain pipe B9, a drain joint 10, a guide pipe 11, a solenoid valve A12 and a liquid level sensor 13. The connecting box 1 is arranged horizontally, and the end of the air inlet pipe 2 extends into the interior on the left side of the connecting box 1, and the end of the air inlet pipe 2 is close to the lower surface of the interior of the connecting box 1. The ventilation holes 4 are arranged in a circular array at equal distances through the end of the air inlet pipe 2 and are located on the pipe wall near the end of the connecting box 1. The end of the air inlet pipe 2 located in the connecting box 1 is sealed. The partition A3 is fixedly connected to the inner wall below the middle of the connecting box 1. The upper end of the partition A3 is separated from the upper end of the interior of the connecting box 1 by a distance. The partition B5 is fixedly connected to the right of the partition A3 On the inner wall of the connecting box 1 on the side, the upper end of the partition B5 is separated from the upper end of the inside of the connecting box 1 by a distance, and the height of the partition B5 is more than five centimeters higher than the height of the partition A3. The outlet end of the air outlet pipe 6 is connected to the upper surface of the right end of the connecting box 1, and the end of the drain pipe A7 is connected to the lower end of the connecting box 1 corresponding to the partition A3 and the partition B5. The liquid inlet end of the liquid inlet pipe 8 is connected to the lower surface of the connecting box 1 near the left end, and one end of the drain pipe B9 is connected to the lower surface of the right end of the connecting box 1. The drain joint 10 is equidistantly connected from bottom to top on the surface of the left side of the connecting box 1, and the guide pipe 11 is connected to the outlet end of the drain joint 10 respectively. The solenoid valve A12 is fixedly connected to the pipe body of the guide pipe 11 near one end of the drain joint 10, and the liquid level sensor 13 is equidistantly fixedly connected to the inner wall of the rear side of the connecting box 1.

Specifically, the upper and lower ends of the connecting box body 1 are arc-shaped, which is convenient for the complete discharge of gas or liquid. The arranged air inlet pipe 2 extends into the position near the bottom of the connecting box body 1, which is convenient for covering the liquid surface during air intake. When in use, a certain amount of water or a certain flow rate is injected into the left side of the connecting box body 1 through the arranged liquid inlet pipe 8, so as to immerse the end of the air inlet pipe 2. The ventilation holes 4 equidistantly opened at the end of the air inlet pipe 2 can discharge the gas in a dispersed manner. When setting, the aperture size and density can be set according to the required gas flow rate to ensure the stable flow rate of the discharged gas. The arranged partition A3 can block the liquid, so as to form a higher liquid level on the left side of the connecting box body 1. The arranged partition B5 is higher than the partition A3, and can make the floating oil on the left side follow the liquid to flow to the right into the partition A3 and in the high water level liquid sealing state. The liquid is discharged to the outside through the drain pipe A7 between the partitions B5. A collecting container is installed on the outside, and the collecting container is not connected to the external atmosphere. The gas is discharged to the outside through the outlet pipe 6. When changing different exhaust pressures, it is only necessary to control the opening and closing of the solenoid valve A12, so that the liquid level enters the guide pipe 11 through the drain joint 10, and then flows into the external collecting container to achieve drainage to the left side to meet the adjustment requirements of different heights. The height of the collecting container is lower than the bottom of the connecting box 1, and a pump body can also be used for extraction. The set liquid level sensor 13 can obtain the internal liquid level information, so as to achieve rapid adjustment. Compared with the traditional single liquid level height water seal structure, it has better flexibility and faster adjustment speed, greatly reduces the installation and adjustment cycle, does not affect production, and has good application prospects.
