Abstract

The invention discloses a furnace feeding system for preparing acid from a sulfur-containing material. The furnace feeding system for producing acid from the sulfur-containing material is characterized in that the material is output from the bottom by a feeding device and delivered to a feeding port of a fluidized bed furnace: material control devices are controlled by drivers to be drawn to change the feed opening size, so that the speed of the sulfur-containing material entering the feeding device is changed; the material control devices are fixedly connected with the drive ends of drivers,the drivers are automatically controlled by external electric control, manual labor is avoided, and feeding of the sulfur-containing material is more convenient and faster; auxiliary materials can beadded quantitatively, the utilization efficiency of resources is improved to the greatest extent, and the proportion between the materials is adjustable; the feeding situation and material combustionsituation in the furnace can be observed in time by a rotary high-temperature resistant lens, so that workers can accurately master feeding time and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of feeding systems, in particular to a boiler feeding system for acid production using sulfur-containing materials. Background technique [0002] At present, the process of using sulfur-containing materials to produce acid is as follows: after the sulfur-containing materials are crushed, they are sent to a fluidized fluidized furnace for combustion, and the sulfur dioxide gas produced enters the converter after cooling, dust removal, and drying, and is converted into sulfur trioxide by catalysts. The gas is sprayed and absorbed by the acid spray device of the absorption tower to make concentrated sulfuric acid. [0003] During the acid production process, it is necessary to feed materials to the fluidized fluidized furnace for combustion to generate furnace gas. The main component of the furnace gas is sulfur dioxide gas. Now it is transported to the feeding port by rubber conveyor belt, and the feeding port...
