Coal water mixture follows the tracks of the principle of work of batching control system:
The present embodiment is selected and can be done man-machine interface with the embedded computer of DCS system communication, arrange on the touchscreen coal dust, fresh water (FW), adjuvant enter to grind ratio value, respective flow value and other parameter, the concentration value of described embedded computer required by coal water slurry process and raw materials used water percentage, calculate out the actual expense of coal water mixture preparation technology coal dust, adjuvant, calculate out the actual magnitude of recruitment of fresh water (FW) simultaneously, complete composition proportion calculating prepared by coal water mixture thus.After composition proportion is determined, described embedded computer is according to the actual expense of pure coal dust, pure adjuvant and fresh water (FW), be converted to the formulation by weight selecting raw material, namely determined pulverized coal flow value, additive stream value and fresh water (FW) flow value needed for subordinate's control hierarchy function.
Three microcomputerized controllers perform the flow instruction of coal dust, adjuvant and fresh water (FW) respectively, start feeding device, when the specification value that certain feed stream value does not reach or overweight is filled a prescription of coal water mixture, microcomputerized controller is then constantly accelerated by frequency-variable controller or the travelling speed of the feeding device that slows down, make it the specification value that flow value constantly approaches formulation by weight, realize the Self-tuning System of raw material batcher, free excellent, the impact of its flow rate fluctuation is controlled at minimum state.In control procedure, with the flow rate fluctuation of coal dust batcher for main contral parameter, adjuvant feed pump and fresh water (FW) the feed pump then coal dust of formula tracking by weight proportion batcher fluctuate in proportion, guarantee the accuracy of each raw material real-time traffic ratio in coal water mixture preparation process.
Coal dust belt feeder, coal powder spiral batcher control principle: when belt feeder or screw feeder are in automatic control state, microcomputerized controller receives the pulverized coal flow value instruction while controlling (depart from touch-screen directly can arrange pulverized coal flow value on microcomputerized controller) of touch-screen, by the rotating speed of Frequency Converter Control belt feeder or screw feeder; Simultaneously the weight signal of coal dust and the rate signal of belt feeder motor or screw feeder motor on the belt feeder that provides of microcomputerized controller Real-time Collection LOAD CELLS or screw feeder, carry out computing by microprocessor.By the real-time flow data that calculates compared with the flow value of setting, then deviate adjustment is carried out, namely immediately regulated the motor speed of belt feeder or screw feeder by frequency converter, make real-time flow data level off to setting flow value, realize the object of dosing.During Non-follow control state, the tachometer value of belt feeder or screw feeder is directly set on microcomputerized controller, realizes closed-loop control by the constant speed of frequency converter to belt feeder or screw feeder, realize the object of dosing.
Feed pump (synchronously using with flowmeter) control principle: when being in automatic control state, microcomputerized controller receives fresh water (FW) flow value and the dilution additive flow value instruction (depart from when touch-screen controls and directly can arrange flow value on microcomputerized controller) of touch-screen, by the rotating speed of Frequency Converter Control pipeline feed pump motor; Simultaneously the flow signal of the fresh water (FW) that provides of microcomputerized controller Real-time Collection pipeline flowmeter or dilution additive, carries out computing by microprocessor.By the real-time flow data that calculates compared with the flow value of setting, then carry out deviate adjustment, namely immediately regulated the motor speed of pipeline feed pump by frequency converter, make real-time flow data level off to setting flow value, realize dosing requirement.During Non-follow control state, the tachometer value of feed pump is directly set on microcomputerized controller, realizes closed-loop control by the constant speed of frequency converter to feed centrifugal pump, realize dosing requirement.
Weightlessness declines batcher control principle: under automatic control state, after small feed bin fills it up with raw material first, and microcomputerized controller controls micro-batcher by the set-point (kg/h) of setting to start by predetermined amount of flow value feed.The electric signal directly weight being converted to correspondence by LOAD CELLS when the reduction of raw material in small feed bin sends microcomputerized controller to, preset flow value is compared with actual flow value, control the rotating speed of micro-batcher according to deviate Drazin inverse amount signal, thus reach the object of dosing.When in little storehouse, raw material is lower than setting, feeder is dosed to toward small feed bin and buys securities with all one's capital.Period, micro-batcher was by the constant operation of last spot speed, to be fed complete, and micro-batcher proceeds to again the metering of weight feed.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
