[0002] Column is one of the very important equipment in chemical industry, petroleum chemical industry and refining, and common column generally has metal material column, non-metal material column, composite material column and other special material column (such as graphite column, titanium alloy column).

[0003] In metal material column, ordinary metal material column and non-metal material column are not suitable for storing strong acid, especially under high concentration and high temperature conditions, such as ordinary stainless steel column can only resist 5% or less dilute sulfuric acid, 316 molybdenum-containing stainless steel column can only resist 15% concentration or less sulfuric acid solution without flow rate, without scouring, without aeration at room temperature, and is not suitable for strong acid storage.

[0004] In non-metal material column, most columns such as polyethylene (PE) column, polypropylene (PP) column and polyvinyl chloride (PVC) column are not suitable for storing strong acid, and only polytetrafluoroethylene (F46) column can store 200℃ or less sulfuric acid or fuming sulfuric acid, which has high cost and is usually used for scientific research rather than daily industrial use.

[0005] Glass fiber lined glass steel column is a kind of composite material structure using glass fiber as reinforcing material combined with resin matrix (such as epoxy resin, polyurethane resin, etc.), which has both corrosion resistance of plastic and strength and durability of glass steel. This material can effectively ensure the safe storage of liquid or gas in column due to its light weight, high strength, heat resistance, corrosion resistance and electrical insulation, and has long service life, especially in special occasions such as petroleum, chemical industry, medicine and other fields. In daily storage and transportation operation, chemical liquid mixed by various materials needs to be stored and placed in column, especially when storing industrial strong acid such as sulfuric acid, various columns cannot be used for storing strong acid because they cannot withstand strong acid corrosion, but glass fiber reinforced composite column can be used for storing strong acid due to its high corrosion resistance.

Concentrated acid diluter is essential in the production process of sulfuric acid, the traditional diluter is to insert the process water pipe directly below the liquid surface. When diluting concentrated sulfuric acid, a large amount of heat is released.

The dilution equipment for sulfuric acid has high efficiency in preparing dilute sulfuric acid. However, the water inlet pipe is directly inserted into the sulfuric acid solution to dilute the sulfuric acid, and the single outlet can cause violent reaction in the local part, generate a large amount of heat and cause production accidents.
