Automatic control method, device and equipment for sulfur content in mixed gas and medium

The invention discloses an automatic control method, device and equipment for sulfur content in mixed gas and a medium. The method comprises the following steps: mixing and configuring a plurality of configuration gases according to a preset proportion to obtain mixed coal gas; collecting at least one configuration gas real-time parameter of each configuration gas, and estimating the sulfur content in the mixed gas according to the configuration gas real-time parameters; if it is determined that the sulfur content does not meet the low-sulfur-content emission condition, calculating the sulfur dioxide contribution degree of each configuration gas to the mixed gas according to at least one configuration gas real-time parameter of each configuration gas; and according to each sulfur dioxide contribution degree, re-determining the proportioning amount of each configuration gas when the mixed gas is generated, so as to obtain the mixed gas meeting the low-sulfur emission condition.
