Description

Associated gas condensate automatic drain device

technical field

The utility model relates to an automatic drainage device for associated gas condensate, which belongs to the technical field of associated gas condensate drainage.

Background technique

Oil well produced fluid contains a large amount of associated gas. When the ambient temperature and pressure change, the heavy components in these associated gases will condense and become condensate. If the condensate is not discharged in time, it is easy to flow back into the gas pipeline and the gas supply pipeline of the heating furnace, causing the pipeline to freeze and block in winter, causing a condensate oil flash explosion accident.

At present, the associated gas condensate in domestic oil and gas processing stations mainly relies on manual discharge, that is, during production and operation, the operator needs to frequently open the outlet valve of the gas-liquid separator to discharge the condensate, especially once every two hours in winter operation , Some sites even have to be opened every ten minutes, which is very labor-intensive. Moreover, relying entirely on the staff's visual inspection and heard sounds for manual discharge, the removal effect is very poor. For some oil fields with high hydrogen sulfide content, frequent manual discharge of condensate will increase safety hazards. After the condensate is discharged, the valve is not closed in time, which will cause a large amount of gas to escape into the atmosphere, causing environmental pollution and waste of resources. .

Detailed ways

The embodiment of the utility model is further described with reference to Fig. 1 and 2:

Example:

The automatic drainage device for associated gas condensate consists of liquid inlet 1, liquid outlet 2, balance valve port 3, lever 4, floating ball 5, floating ball holder 6, body 7, valve nozzle 8, valve seat 9, gate valve 11, filter 12, gate valve 2 13, gate valve 3 14, gate valve 4 15, heat tracing device 16 and strut 17:

The body 7 (circular, rectangular or oval) of the associated gas condensate automatic draining device is provided with a liquid inlet 1 at the upper end, with a balance valve port 3 on the side wall, and with a liquid outlet 2 at the bottom. The upper part of the liquid outlet 2 is a valve seat 9 located in the body 7 , and the upper end surface of the valve seat 9 is provided with a strut 17 . One end of the lever 4 is connected to the support rod 17 , and the other end is connected to the floating ball holder 6 , and the lever 4 is provided with a valve mouth 8 corresponding to the valve seat 9 . Float ball 5 is connected above the float support sheet 6 .

The front of the body 7 liquid inlet 1 is connected to the filter 12 and the gate valve 11 connected to the gas-liquid separator 10, the liquid outlet 2 of the body 7 is connected to the gate valve 2 13 and the dirty oil tank, and the pipeline in front of the gate valve 11 is connected to the pipeline behind the gate valve 2 13 There is a gate valve three 14, and a gate valve four 15 is connected between the gas-liquid separator 10 and the liquid inlet 1 of the body 7 or the balance valve port 3. All components of the automatic liquid draining device are connected by pipelines, and heat tracing devices 16 are arranged outside each pipeline.

The working principle of the utility model is as follows:

The condensate flows out from the gas-liquid separator 10, passes through the gate valve 11 and the filter 12, and enters the body 7 of the automatic liquid draining device from the liquid inlet 1. During normal operation, the automatic drain device operates normally, and enters the dirty oil tank through the normally open gate valve 213. Before the incoming liquid level reaches the balance point of the lever 4, the floating ball 5 does not move; when the incoming liquid level exceeds the equilibrium point of the lever 4, the floating ball 5 floats up, driving the floating ball holder 6 to rise, and is acted by the lever 4 , lift the valve mouth 8, open the liquid outlet 2, and form automatic liquid discharge.

The gate valve four 15 is connected to the gas-liquid separator 10 and the liquid inlet 1 or the balance valve port 3 of the automatic liquid discharge device, which can effectively avoid the formation of air resistance in the liquid discharge device and affect the normal liquid discharge. The filter 12 that is located in front of the automatic drain device can regularly clean up the dirt in the liquid to ensure its smooth passage. When the automatic draining device breaks down, the gate valve 314 can be manually opened to drain the liquid, and the automatic draining device can be repaired.
