Embodiment 1

[0024] A method for installing lightning protection and grounding equipment for benzene hydrogenation engineering is characterized by comprising the following steps:

[0025] a. Install the grounding body. The buried depth of the grounding body shall not be less than 0.6m at the top. The angle steel and steel pipe grounding bodies shall be arranged vertically, and the spacing of the vertical grounding bodies shall not be less than 2 times their length, and the spacing of the horizontal grounding bodies shall not be less than 5m. The buried position is not less than 1.5m away from the building; the grounding body is connected by welding, and its welding length is: galvanized flat steel is not less than twice its width, not less than three sides welding, and the welding length of galvanized round steel is equal to its diameter. 6 times and double-sided welding. When galvanized round steel is connected to galvanized flat steel, its length is 6 times the diameter of round steel. When ...

Abstract

A mounting method of lightning protection and grounding equipment in the benzol hydrogenation process is characterized by including the following steps of a, mounting a manual grounding body, b, mounting an artificial grounding body, c, laying grounding main wires, d, mounting a lightning conductor, e, mounting a support, f, embedding lightning protection downleads, g, laying lightning protection downleads in an exposed manner, h, mounting a lightning conduction net, and i, testing resistivity values. The mounting method of the lightning protection and grounding equipment has the advantages of reasonable design of mounting steps, simplicity in operation, safety and reliability in process quality, excellent electric performance and lower process cost.

Description

Technical field [0001] The invention relates to a method for installing lightning protection and grounding equipment, in particular to a method for installing lightning protection and grounding equipment for benzene hydrogenation projects. Background technique [0002] The process of the benzene hydrogenation unit is special, the system is complicated, the equipment is many, the pressure and temperature of the system itself are high, and the pump equipment is not allowed to run idly. The benzene hydrogenation project is mainly divided into the central control room and substation, refining equipment, water supply and drainage engineering, air compressor station, storage and transportation facilities (tank area and pump room), power supply of the whole plant, lighting of the whole plant, hydrogen production station, etc. In part, there are special requirements for lightning protection, fire protection, and explosion protection in the electrical installation of these facilities. The...
