An Intrinsically Safe Pipeline Oil Static Eliminator

Abstract

The invention provides an intrinsically safe pipeline oil static eliminator, which mainly solves the problem that the oil static electricity in the pipeline cannot be completely eliminated under the current technical conditions. Density monitors, power supplies and controls. The pipeline is the body of the static eliminator; the connecting flange is used to connect the static eliminator in series on the pipeline; the discharge needle is connected to the pipeline; the insulation module is used to ensure that the discharge needle and the pipeline will not be broken down by high voltage; It is used to detect the electrostatic charge of the oil in the pipeline, and upload the data to the control module; the power module is used to output voltage; the control device receives the data from the oil charge density monitor, controls the output of the power module, and acts as an oil charge density monitor When the detected data exceeds the set value, the control device controls the output of the power module to completely neutralize the oil static electricity in the pipeline to realize the intrinsic safety of oil static electricity.

Description

technical field [0001] The invention relates to a static eliminator for inflammable and explosive places such as petrochemical oil gas storage and transportation, in particular to an intrinsically safe pipeline oil static eliminator. Background technique [0002] In the process of oil product transportation in petrochemical enterprises, due to reasons such as low oil conductivity, excessive oil delivery speed, and impurities in the oil product, a large amount of static electricity will be generated during the oil product transportation process, and static electricity will bring safety hazards. The "General Guidelines for the Prevention of Electrostatic Accidents" (GB 12158-2006) and the "Static Safety Regulations for Liquid Petroleum Products" (GB 13348-2009) clearly stipulate that a liquid static eliminator can be installed at the end of the pipeline to reduce the accumulation of static electricity. However, the passive static eliminator eliminates the static electricity of...

Problems solved by technology

Although this device can also eliminate the static charge near the front of the needle tip, the static electricity between the needle tip and the catheter cannot be effectively eliminated, and it is the friction between this part of the oil and the insulating pipeline that will aggravate the generation of static electricity, and also exists in the pipeline. After the needle tip is worn out due to oil impact, the electricity dissipation effect drops sharply

Therefore, most of the existing static elimination devices cannot effectively eliminate the static charge of the oil transported in the pipeline.

In addition, in the process of neutralizing the charge with the discharge needle, sometimes the discharge voltage of the discharge needle is too large, resulting in the breakdown of the connection between the discharge needle and the pipeline, resulting in serious wear and tear of the pipeline, and the indeterminate discharge volume leads to waste of power and Dangerous accidents caused by excessive discharge voltage resulting in overload of oil charge
