Description

Technical Field

[0001] The utility model relates to the field of oil and natural gas gathering and transportation equipment, in particular to a tank liquid level alarm device. Background Art

[0002] For well sites in the middle and late stages of exploitation, the gas wells adopt the bubble drainage process to increase production. The bubble drainage process will bring gas field water out from the wellhead of the gas well. The discharged gas field water needs to be separated by separation and filtration equipment, and the gas field water is collected in the gas field water tank for storage. The gas field water is collected by a special water truck and transported to the sewage treatment plant for treatment, thereby avoiding environmental pollution.

[0003] At present, the liquid level in the gas field water tank is judged by observing the magnetic float level gauge installed outside the tank. The on-duty personnel need to observe the magnetic float level gauge many times during the gas field water collection process and judge the liquid level height in the gas field water tank based on experience. However, since the magnetic float level gauge does not have an alarm prompt function, if the operating personnel are negligent or misjudge, it is very easy to cause the gas field water to overflow from the gas field water tank, affecting the normal operation of the separation and filtration equipment, and thus affecting the production efficiency of natural gas.

[0004] Therefore, there is an urgent need for a technical solution to solve the technical problem that the currently used gas field water tanks do not have an alarm function. Utility Model Content
