Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of all.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to shown in Fig. 1, it is the utility model fluidized bed furnace automatic temperature control system structural representation.Described fluidized bed furnace automatic temperature control system, comprising:
Be arranged on the determination of oxygen content instrument 101 of fluidized bed furnace fume desulfurizing tower outlet, be arranged on the pressure of bellows table 103 of air blast bellows; And be arranged on fluidized bed furnace temperature measuring instrument 102, the burner hearth internal pressure measuring instrument 104 of fluidized bed furnace;
Control device 105, input is connected with described determination of oxygen content instrument 101, the pressure of bellows table 103, fluidized bed furnace temperature measuring instrument 102, burner hearth internal pressure measuring instrument 104 respectively, and output is connected with feeder 107, air blast and return air flashboard 109, air-introduced machine 108.
In a preferred embodiment of the present utility model, described fluidized bed furnace automatic temperature control system also comprises temperature setting device 106, is connected with described control device 105.
In a preferred embodiment of the present utility model, described control device 105 is programmable logic controller (PLC) (PLC), and certain described control device 105 also can realize the device of controlling functions for other.Described programmable logic controller (PLC), comprising: judge module, and when actual temperature, to reach setting value temperature required, and oxygen content higher than operating mode actual value, then sends the signal of coal-supplying amount deficiency; Processing module, receives the signal of described coal-supplying amount deficiency, improves feeder coal-supplying amount.
With reference to shown in Fig. 2, it is the system architecture schematic diagram of the utility model application.
Specifically, in the outlet of fluidized bed furnace fume desulfurizing tower, determination of oxygen content instrument is installed, the oxygen content (such as 10%) of flue gas is discharged under measuring operating mode, in fluidized bed furnace running, set one temperature required (such as 800 degree), and make signal import PLC into, PLC is according to actual temperature, the pressure of bellows, burner hearth internal pressure adjustment feeder coal-supplying amount, blower air quantity, air-introduced machine air quantity, if temperature reaches setting value temperature required (such as 800 degree), oxygen content is but higher than operating mode actual value (such as 12%), then judge that coal-supplying amount is not enough, PLC sends warning rapidly, and make adjustment, improve feeder coal-supplying amount, make the fired state that fluidized bed furnace reaches desirable.
Above-described detailed description of the invention; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only detailed description of the invention of the present utility model; and be not used in restriction protection domain of the present utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
