Where should the lightning rod of a distillation tower be installed?
Thread Content
For a column section composed of distillation columns for flammable organic compounds, with a maximum height of 60 m, what are the requirements for installing lightning rods? How many do I need to install? How to distribute it?
The protection range of a lightning rod is within an angle of 45 degrees; with these conditions, it’s not possible to give you any further advice.
Bro, according to the new lightning protection design, as long as the thickness of your tower wall is over 4 mm, it’s not necessary to install a lightning rod; the tower itself can be used as a lightning receptor. For specific details, refer to the electrical specifications or consult an electrical professional.
1. Installation specifications for lightning rods and lightning conductors: Refer to Sections 25 and 26 of the Code for Acceptance of Construction Quality of Building Electrical Engineering, GB5.303–2002. 2. Points to note in practice: In addition to conducting inspections in accordance with the specifications, the following should also be taken into account: (1) Lightning rods: 1) The lightning rod should be cut into upper, middle, and lower sections according to the designed length; 2) When the height of the lightning rod exceeds 5 meters, wind-resistant tie rods should be used in groups of 3. 3) The steel plate under the lightning rod must be firmly connected to the concrete base. 4) The thickness of the tip of the lightning rod should be no less than 3 MM. (2) Lightning protection strips: 1) When using the rebar inside columns as conductors for concealed installation of lightning protection strips, the diameter of the rebar should be at least 12 mm; the rebar should be joined together by single welding. 2) When the length of the roof exceeds 18 meters, in addition to being installed along the perimeter of the building, concrete blocks should also be placed on the roof panels, with clamps embedded in these concrete blocks, and the lightning protection strips laid along those blocks.
It seems that none of the towers these days have lightning rods, right? Just use the grounding device directly, right?
That’s absolutely correct. According to the design specifications for chemical equipment, as long as the wall thickness of the tank top exceeds 4 MM, it is not necessary to install a lightning protection device, but good grounding is required.
