Development of an Automatic Protection Device for Electric Control and Monitoring of Blowing Ash Pipeline Blockage
In order to prevent dust pollution,the oil drilling site uses ash tank for the preparation of weighted drilling fluid.Ash tank is a pressure vessel,driven by compressed air with pressure pressure of 0.7～1mpa,equipped with pressure gauge and pressure relief valve and tested regularly.When the security equipment is stuck and the discharge pipe is blocked abnormally,it is easy to cause unsafe events of sudden pressure release.This paper analyzes the causes of unsafe elements,and designs a device according to preventive measures to solve this problem.
