Automatic water replenishing control system for slag removal

An automatic water replenishing control system for slag removal, comprising:

• a monitoring unit, used for building a plurality of monitoring points according to circulation path of cold slag water;
• wherein the monitoring unit further comprises a plurality of monitoring sub-modules, wherein the monitoring sub-modules are used for collecting cold slag water parameters at each of the monitoring points;
• a central control unit, used for generating cold slag water loss parameters according to boiler operation parameters, and judging whether to generate a primary water replenishment plan according to the cold slag water loss parameters;
• wherein the central control unit is further used for generating a cold slag water evaluation value according to water quality parameters of cold slag water at each of the monitoring points, and setting a secondary water replenishment plan according to the cold slag water evaluation value;
• a water replenishing unit, wherein the central control unit sets working parameters of the water replenishing unit according to the primary water replenishment plan and the secondary water replenishment plan;
• wherein the central control unit comprises:
• a first processing module, used for setting a plurality of feedback time nodes and building a plurality of monitoring periods according to the feedback time nodes;
• a second processing module, used for obtaining slag parameters and generating cold slag water accumulated loss amount at each of the feedback time nodes according to a preset slag-cold slag water loss model;
• wherein the second processing module is further used for judging whether to generate the primary water replenishment plan according to the cold slag water accumulated loss amount;
• a third processing module, used for building a monitoring point sequence H according to position parameters of each of the monitoring points, and H=(h1, h2 . . . hi . . . hm), wherein m is a number of the monitoring points and hi is i-th monitoring point of cold slag water being passed after flows out of a overflow pool;
• a fourth processing module, used for obtaining water quality parameters of each of the monitoring points obtained by current feedback time node, and building an impurity content difference value sequence F of the current feedback time node, and F=(f1, f2 . . . fi . . . fm-1), wherein fi is impurity content difference value between i+1-th monitoring point and i-th monitoring point of the current feedback time node;
• a fifth processing module, used for generating a cold slag water evaluation value at the current feedback time node, and judging whether to generate the secondary water replenishment plan according to the cold slag water evaluation value at the current feedback time node.
