Technical Field

The utility model relates to the technical field of industrial waste sulfuric acid recycling, in particular to pyrite-doped waste sulfuric acid burning equipment convenient to use.

Background

In recent years, the gasoline alkylation process produces more than 100 ten thousand tons of waste sulfuric acid per year, and as the quality of gasoline increases, this wastes both sulfur resources and causes environmental pollution. At present, four methods for treating waste sulfuric acid at home and abroad mainly exist: concentrating and recovering, neutralizing, comprehensive utilization and cracking regeneration. The use of cracking recovery of alkylated spent sulfuric acid is currently the more popular method, with the cracking process being carried out in a horizontal cracking furnace. Because the waste sulfuric acid is required to absorb heat during cracking, the system for producing sulfuric acid by taking pyrite as a raw material adopts the combined treatment of adding fuel, spraying sulfur and hydrogen sulfide gas during the cracking, and the system for producing sulfuric acid by roasting pyrite in a fluidized bed furnace simultaneously carries out the cracking of the waste sulfuric acid, thereby creating a new way for producing acid by cracking the waste sulfuric acid and having strong applicability and economy.

However, the existing most pyrite-doped waste sulfuric acid equipment adopts the way that the furnace gas of a fluidized bed furnace directly enters a heat exchanger to exchange heat with air for cooling, and the heat exchanger is blocked quickly due to high dust content of the gas, so that the heat exchanger cannot normally operate.
