Abstract

The invention relates to a regulation and control method for improving waste heat recovery efficiency of a sinter vertical cold kiln cooling process. The technical problem that an existing sinter vertical cold kiln cooling process lacks key parameter regulation and control is mainly solved. According to the technical scheme, the regulation and control method for improving the waste heat recovery efficiency of the sinter vertical cold kiln cooling process comprises the specific steps that (1) the temperature is set, wherein the range of the cooling air kiln drawing temperature is set to be min (380) lt in an MATLAB program; tgoo (i) lt; max (450) to obtain an optimal energy recovery effect; 2) establishing a temperature control equation, namely establishing a temperature control equation of cooling air and sinter temperature, and solving a sinter kiln entering temperature tmi (i) and a cooling air kiln entering temperature tgi (i) in a sintering regulation process; 3) iteratively calculating the optimal solution range: obtaining the optimal solution range of the sintering ore kiln entering temperature tmi (i) and the cooling air kiln entering temperature tgi (i); and (4) three key parameters are regulated and controlled, specifically, the cooling air kiln entering temperature tgi (i), the sinter kiln entering temperature tmi (i) and the cooling air kiln entering speed omegagy are regulated and controlled based on the optimal solution range in the step (3).
