A Refined Reactor with Lightning Protection Function

Abstract

The invention provides a refining reactor with a lightning strike protection function. The refining reactor comprises a refining reactor body, wherein the top of the refining reactor body is providedwith a feeding pipe; the feeding pipe is provided with a feeding valve; the feeding valve is connected with a pneumatic motor used for driving the feeding valve to open and close; the top of the refining reactor body is provided with an insulation rod; the top of the insulation rod is provided with an insulation box; a plurality of discharging electrodes in vertical arrangement are arranged in theinsulation box; an air gap is formed between the discharging electrodes; the insulation box is provided with air holes aligned with the air gaps; a metal pin is arranged on the discharging electrode;the insulation box is connected with the pneumatic motor through a main pipeline. Lightning strike is introduced onto the discharging electrode and releases the energy through the air gap; the breakdown air expands for blowing out the electric arc through the through hole; the arc extinguishing effect is achieved. The expanded air is transmitted to the pneumatic motor through the main pipeline; the feeding opening is closed; the hydraulic gas leakage is prevented; the expanded air is in a high-pressure state in the insulation box; the high-pressure air drives the pneumatic motor to close thefeeding valve through the main pipeline.

Description

technical field [0001] The invention relates to the technical field of refining reactor equipment, in particular to a refining reactor with lightning strike protection function. Background technique [0002] Hydrocracking is a process in the petrochemical industry, that is, in the process of petroleum refining, under high pressure and temperature, hydrogen is used as a catalyst to make heavy oil hydrogenation, cracking and isomerization reactions, and convert it into light Oil processing. For multi-bed refining reactors, the height of the refining reactor is generally very high, and in some cases the refining reactor is installed outdoors. Since the refining reactor is made of metal, the refining reactor is easily struck by lightning in areas with high lightning incidence. The refining reactor is filled with hydrogen, and the consequences of leakage will be disastrous. The current refining reactor has no lightning protection function, and cannot automatically close the fee...
