Automatic blocking judgment device for gas pipeline filter separator and automatic blocking judgment method

Abstract

The invention discloses an automatic blocking judgment device for a gas pipeline filter separator, comprising a first gathering pipe, a second gathering pipe and two branch main pipes between the first gathering pipe and the second gathering pipe. Each of the branch main pipes is successively provided with a valve, a pressure gauge, a cyclone separator, a filter separator, a pressure gauge, a flow transmitter and an electric valve. The differential pressure transmitter is mounted on the filter separator; a differential pressure transmitter is installed on the filter separator. The differential pressure transmitter, the flow transmitter and the electric valve are all connected to a junction box, which has an access to a control system. The invention also discloses an automatic blocking judgment method for the gas pipeline filter separator. The invention has the beneficial effects as follows: whether the gas pipeline filter separator is blocked can be monitored in real time, the alarm speed is timely and the accuracy rate is high, the operation efficiency of the gas pipeline is improved, and the energy loss is reduced.

Description

technical field [0001] The invention relates to the technical field of pipeline systems, in particular to an automatic blocking detection device and an automatic blocking detection method for a filter separator of a gas transmission pipeline. Background technique [0002] During the operation of the pipeline, due to impurities in the gas, one or several filter separators are blocked, resulting in a large pressure loss when the gas passes through the filter, which eventually leads to an abnormal increase in energy consumption and reduces the benefits of the enterprise. And brought adverse effects to the enterprise. If you do not grasp the relevant information such as whether the filter separator is clogged in time, and deal with it in time, the clogging will continue to increase, the energy consumption will continue to increase, and eventually the filter element will be damaged. [0003] As for whether the filter separator of the gas transmission pipeline is blocked, the pre...

Problems solved by technology

[0002] During the operation of the pipeline, due to impurities in the gas, one or several filter separators are blocked, resulting in a large pressure loss when the gas passes through the filter, which eventually leads to an abnormal increase in energy consumption and reduces the benefits of the enterprise. and adversely affect the business

If you do not grasp the relevant information such as whether the filter separator is clogged in time, and deal with it in time, the clogging will continue to increase, the energy consumption will continue to increase, and eventually the filter element will be damaged.

[0003] As for whether the filter separator of the gas pipeline is blocked, the previous projects could not automatically judge, and the blockage of the filter separator could not be found in time, so that the relevant problems could only be found during fixed periodic maintenance.
