Increase, burning in-furnace temperature is excessively high, sulphur can be made to distil, cannot efficiently use raw material sulphur.Especially this combustion furnace application
In cornstarch processing in the production of corn soaking sulfurous acid, above-mentioned many defects are had.Itself the reason is as follows that:
, need to be to corn soaking in production of corn starch process, raw material used by impregnating is food grade sulfurous acid, mesh
Preceding maize production enterprise is not easy to buy the sulfur dioxide of the food grade for producing sulfurous acid on the market, even if Some Enterprises
Outsourcing obtains food grade sulfur dioxide, and sulfur dioxide is injected in industrial water, and the sulfurous acid that preparation meets production requirement is used for
In the immersion of cornstarch, but the sulfur dioxide bought not very meets country since its production process is not easily-controllable or uncontrollable
Related regulation, therefore this method is eliminated.
Maize production enterprise buys food grade sulphur, carries out burning and generates sulfur dioxide, prepares sulfurous acid with water absorption, should
The defect of method is that the existing maximum burning capacity of sulphur stove is 100-150kg/h, with the increase of quantity combusted, combustion
It burns the temperature in furnace necessarily also to increase, burning in-furnace temperature is excessively high, sulphur can be made to distil, cannot efficiently used.
Therefore, it is necessary to be improved for above-mentioned defect, the combustion furnace for preparing sulfurous acid as raw material using sulphur is carried out
It improves, the sulfurous acid quality for producing the combustion furnace meets the requirement of institute, enterprise converted products, and makes the combustion furnace of design most
The phenomenon that avoiding sulphur distillation that from cannot being used effectively using raw material sulphur of limits.
