In particular, the device comprises:
the large ball barrel is arranged at the tail end of the automatic ball collecting device and used for receiving the spherical pig;
a small ball cylinder with a smaller cylinder diameter than the large ball cylinder, wherein the small ball cylinder is connected with the large ball cylinder through an eccentric reducing large head pipe and an eccentric reducing small head pipe;
the rubber buffer device is arranged at the tail end of the large ball barrel and prevents mechanical damage caused by too high ball entering speed;
the eccentric reducing large-small head pipe is a same pipe barrel and is provided with a large head end and a small head end, the large head end is connected with the large ball barrel, and the small head end is connected with the small ball barrel;
and the automatic control system comprises a sensor, an automatic control valve and an automatic control system.
In the present embodiment, the automatic control system is added to the conventional ball collecting device. Comprises a sensor, an automatic valve and an automatic control system to realize the automatic work of the ball collecting device.
In some embodiments, with respect to the automatic control system, it is further manifest that the sensors thereof comprise:
the monitoring station is arranged at a position with a specified distance from the station yard and used for monitoring the spherical pig signals and transmitting the spherical pig signals to the automatic control system;
the ball passing indicator is arranged on the small ball barrel;
and 2 remote pressure sensors, 2 in-situ pressure sensors and a methane detector which are all arranged and connected with the automatic ball receiving device.
In some embodiments, further embodied in the automatic control system is a self-regulating valve comprising:
the emptying valve, the blowdown valve, the communicating valve (ball valve), the nitrogen injection valve, the air inlet valve and the water injection valve are all arranged and connected with the automatic ball collecting device, and the automatic control system is combined to complete impurity discharge and automatic ball collection of the automatic ball collecting device;
and the quick-opening blind plate is arranged at the tail end of the large ball cylinder and the like.
In some embodiments, regarding the automatic control system, the automatic control system further includes:
the data acquisition and monitoring control system receives the monitoring signal of the monitoring station;
and the programmable logic controller comprises a sensor feedback signal receiving module and an automatic control valve control module.
In this embodiment, an automatic control system of the automatic ball collecting device includes: and the field explosion-proof Programmable Logic Controller (PLC) is connected with a data acquisition and monitoring control (SCADA) system.
Furthermore, the data acquisition and monitoring control system in the automatic control system and the programmable logic controller are in bidirectional communication, wherein the data acquisition and monitoring control system provides ball cleaning position information for the programmable logic controller, and the programmable logic controller uploads ball receiving process parameters to the data acquisition and monitoring control system.
Based on the above embodiment, when the automatic ball collecting device works, the automatic control system of the automatic ball collecting device is represented as follows: the monitoring station can be arranged at positions 5 kilometers, 10 kilometers and the like away from the station yard according to the actual situation of the site, so that the ball passing speed can be monitored conveniently, and the arrival time of the spherical pig can be predicted. After the signal of the monitoring station is transmitted into the station SCADA system, the arrival time of the pigeonhole can be calculated. When the ball indicator has a signal to feed back to the PLC, the PLC communicates with the SCADA system. The PLC receives signals of the field sensor and realizes automatic ball collection through the logic control of the switch valve and the blind plate switch.
With respect to the pellet cylinder, in some embodiments, the pellet cylinder has a length 6 to 12 times its cylinder diameter.
The design length of a conventional ball collecting barrel is generally 4-6 times of the barrel diameter, and under the condition that water and hydrates are accumulated in a pipe, the impurities such as the hydrates enter a large ball barrel, so that a spherical pig cannot enter the ball barrel. At the moment, the pressure in the ball barrel is higher, so that safety accidents are easy to happen, or the spherical pig cannot be taken out. The ball collecting cylinder is designed to be lengthened, preferably, in the embodiment, the length of the ball collecting cylinder is set to be 6-12 times according to different pipeline air sources. For gas field gas and inlet gas sources, the gas source contains more water and dust, and the length of the ball cylinder can be set to be 12 times of the diameter. For an LNG source, the length of the ball barrel can be properly shortened.
With respect to the eccentric reducing head pipe, in some embodiments, the eccentric reducing head pipe is a pipe wall with one side smoothly arranged.
The connecting part of the large ball cylinder and the small ball cylinder in the conventional ball collecting cylinder is connected by adopting concentric reducing large heads and small heads. In the process that the spherical pig enters the large ball barrel from the small ball barrel, if the ball inlet speed is too slow, the front end of the spherical pig contacts the bottom of the large ball barrel under the action of gravity, so that the spherical pig is clamped at the large head and the small head. In the invention, the large ball barrel and the small ball barrel are connected by the eccentric pipe, and particularly, one side of the eccentric pipe consisting of the large ball barrel and the small ball barrel is smoothly arranged, namely the side is taken as the bottom, the large pipe barrel hole and the small pipe barrel hole are respectively arranged towards the right left and the right, and the obtained front view is a right trapezoid or similar right trapezoid, so that the spherical pig can smoothly pass through the large head and the small head when passing through at a low speed, and the problem of spherical pig blocking can be effectively solved.
Regarding the rubber buffer device, the running speed of a pipe cleaner in a pipeline is about 15-20km/h, under the condition that the pressure difference between the front and the back of a spherical pig is large, the spherical pig speed exceeds 20km/h, the spherical pig enters too fast, the head of the spherical pig is easy to impact the quick-opening blind plate position of the spherical pig collecting device, and mechanical damage is caused. Therefore, according to the invention, the round rubber buffer device is arranged at the position of the quick-opening blind plate, so that the problem of mechanical damage caused by excessively high ball entering speed can be effectively prevented.
Another embodiment of the present invention provides a ball collecting method based on the automatic ball collecting device, which is further described in detail based on the above embodiments. Firstly, as shown in fig. 1 to 3, the novel ball collecting device adopts the lock ring type quick-opening blind plate 1, and has the advantages of reasonable structure, good sealing performance, rapid opening and closing, easy realization of automatic control, safety, reliability, strong bearing capacity and the like. The ball collecting device adopts an eccentric big head pipe 6 and an eccentric small head pipe 6 to connect a big ball barrel 5 and a small ball barrel 7. The small ball cylinders 7 are all designed to be lengthened, and the length is about 6-12 times of the cylinder diameter.
Secondly, the top of the ball collecting device barrel is also provided with a water inlet, and the bottom is provided with a water outlet. A pressure balance pipe is arranged in front of the large ball barrel and the small ball barrel. The tail end of the large ball barrel is provided with a rubber anti-collision buffer device. Pressure measuring ports are arranged at the upper parts of the large ball barrel and the small ball barrel. The upper part of the large ball barrel is provided with a nitrogen injection hole.
In addition, the ball cylinder of the ball collecting device is connected with the foundation through two saddles, and the saddles are connected with the ball cylinder in a welding mode. The upper side of the ball cylinder is provided with a safety valve for testing the overpressure protection function of the ball cylinder.
