文档介绍:摘要
硫酸是一种高沸点难挥发的强酸,易溶于水,能以任意比与水混溶,作为一个国家强大的标志,在国民生产中起着不可忽视的作用。本设计采用接触法和硝化法来生产硫酸,接触法采用接触物质—触媒,而硝化法则采用含硝硫酸,即是氧化氮的硫酸溶液。两法均以制备二氧化硫为起点,而后再用不同的方法制成硫酸。本设计用硫铁矿为最初原料,在沸腾焙烧炉中进行高温煅烧,再进入电除尘器,旋风除尘器,最后进入废热锅炉产生初始硫酸,再经处理得到所需硫酸。通过物料衡算与热量衡算得出本次设计符合要求。

ABSTRACT
Sulfuric acid is a high boiling point volatile acid difficult to dissolve in water, miscible with water in any ratio, as a powerful symbol of a country, in the national production and plays an essential role. The design method and nitration by exposure to produce sulfuric acid, using the contact material contact method - catalyst, and with nitric acid were used for nitrification, which is nitric oxide sulfuric acid solution. Preparation of sulfur dioxide is the two laws as a starting point, and then re-use made of sulfuric acid in different ways. The design for the initial raw material with pyrite, in the boiling baking in high temperature calcination, re-entering the electrostatic precipitator, cyclone, and finally into the waste heat boiler to create the initial sulfuric acid, sulfuric acid and then processed to obtain the required. Through the material balance and heat balance obtained to meet the requirements of this design.
Keywords: Pyrite, Production, Sulfuric acid, Boiling furnace.
