Problems solved by technology

[0004]1. The equipment on the current branch can only be discharged after the backup branch is activated;
[0005]2. Unable to control the discharge pressure, it is easy to cause damage to downstream equipment and even cause injury to operating personnel;
[0006]3. The automation of sewage discharge is low, and manual sewage discharge operation steps are complicated, which increases the workload of operating personnel and the probability of misoperation

Embodiment 1

[0039] Example 1, such as figure 1 As shown, the embodiment of the present invention is an online sewage discharge device applied to gas pipeline stations. The device includes three filters 1 , six sewage discharge branches 5 , headers 22 , instrument junction boxes 13 and sewage tanks 12 .

[0040] Two liquid collection bags 14 are arranged under each filter 1 , there are six liquid collection bags 14 in total, and each liquid collection bag 14 is provided with a first liquid level transmitter 2 and a second liquid level transmitter 3 .

[0041] One end of each sewage branch 5 is connected to a liquid collection bag 14, and the other end of each sewage branch 5 is connected to the manifold 22, and each sewage branch 5 is sequentially provided with a first safety cut-off valve 6, a first Process ball valve 7, liquid level regulating valve 8 and second process ball valve 9.

[0042] The sewage tank 12 is connected with the manifold 22 , and the third liquid level transmitter 4...

Embodiment 2

[0054] Embodiment 2, an online sewage discharge method applied to an online sewage discharge device in a gas pipeline station, the method includes the following steps:

[0055] Step 1, the first liquid level transmitter 2 measures the liquid level value of the liquid collection bag 14, the first liquid level transmitter 2 judges the liquid level value, and when the liquid level value is a high liquid level value, it turns on The liquid level regulating valve 8 is used to start and trigger automatic sewage discharge;

[0056] When the liquid level value is a low liquid level value, the liquid level regulating valve 8 is closed to stop triggering of automatic sewage discharge;

[0057] When the liquid level regulating valve 8 fails to be closed, the first safety cut-off valve 6 arranged upstream of the liquid level regulating valve 8 is triggered to close.

[0058] At the same time, the first liquid level measurement signal of the first liquid level transmitter 2 is connected t...

Abstract

The invention discloses an online blowdown device applied to a gas pipeline station. The online blowdown device comprises: at least one filter, with at least one liquid collecting pocket arranged below each filter and two liquid level transducers arranged on each liquid collecting pocket; at least one blowdown branch, with one end of each blowdown branch connected to each liquid collecting pocket and the other end of the blowdown branch connected to a header, and a first safety shut-off valve, a first process ball valve, a liquid level regulating valve, and a second process ball valve arranged in order on each blowdown branch; a blowdown tank connected to the header, with a liquid level transducer arranged on the blow-down tank; the header, with a pressure transducer and a second safety shut-off valve arranged thereon; and an instrument junction box connected to the three liquid level transducers, the two safety shut-off valves, the liquid level regulating valve, and the pressure transducer. The invention also provides an online blowdown method applied to a gas pipeline station. The online blowdown device and online blowdown method disclosed by the invention have the advantages of ensuring the safety of operation of the station, reducing the operation risks, and facilitating energy conservation and emission reduction, and may be monitored by means of an SCADA system.

Description

technical field [0001] The invention relates to the technical fields of sewage discharge system, pipeline system and automatic control, in particular to an online sewage discharge device and an online sewage discharge method applied to gas pipeline stations. Background technique [0002] For the sewage system in the gas pipeline station, the traditional device is to set a ball valve and a sewage valve on the sewage branch. When the pipeline is used), first open the backup branch, close the upstream and downstream ball valves that need to be drained, then open the vent valve to vent the natural gas pressure to below the safe operating pressure, then close the vent valve, and finally open the ball valve and the sewage valve for sewage discharge. [0003] The disadvantages of this off-line sewage device are: [0004] 1. The equipment on the current branch can only be discharged after the backup branch is activated; [0005] 2. Unable to control the discharge pressure, it is e...
