Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structured flowchart of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Referring to Fig. 1, the object of the present invention is to provide uniform milling production run infiltration water control system, comprise industrial computer 1, described industrial computer 1 is connected with on-off value data acquisition card 2, analog data collection card 3, human-computer interaction module 4, switching value output module 5, analog output module 6, described analog data collection card 3 is connected with infrared moisture measuring tester 31, Cold water tap aperture table 32, hot-water valve aperture table 33, fluid level transmitter 34, temperature sensor 35, electromagnetic flowmeter 36 and frequency converter 37, described analog output module 6 is connected with cold water electric operator 61, hot water electric operator 62 and frequency converter 37.The present invention detects infiltration water temperature by temperature sensor, electromagnetic flowmeter detects permeate water flow, by industrial computer, receive permeate water flow and the temperature instruction of self scheduling or dispatching, by dispatch command and temperature detection signal comprehensive rear form hot water and the instruction of cold water control valve opening, regulate infiltration water temperature; After comprehensive by dispatch command, electromagnetic flowmeter signal, form frequency converter rotary speed instruction, in order to control infiltration water revolution speed, guarantee that infiltration water supplies with on demand.After No. five squeezers, IR Moisture Measurement Apparatus is set.Bagasse moisture is measured, measurement result is sent into the important parameter that Control Room is controlled as boiler combustion.
As the concrete embodiment of the present invention, described switching value data amount capture card 2 is connected with equipment operation monitoring signaling module 21, equipment failure signaling module 22, system operation signal module 23 and automatic/hand handover module 24.Described switching value output module 5 is connected with fault acousto-optic alarm module 51 and duty display module 52.
Height and the amount of seepage of squeezing sucrose extraction number in close relations.Increase amount of seepage, can improve sucrose extraction, but can make mixed juice hammer degree reduce simultaneously, during evaporation, quantity of steam increases, and squeezes roll row juice load simultaneously and increases the weight of.When amount of seepage is few, makes to squeeze sucrose extraction and reduce, economic benefit declines.Not proportional between amount of seepage and sucrose extraction.After amount of seepage is increased to a certain degree, then increase the water yield, the increase of gained sugar is very few.Domestic sugar refinery mostly adopts the amount of seepage of 14～20% pairs of sugarcane ratios.
It is a following control system that infiltration water interlock is controlled, and according to current pressing quantity thereof, system detects current amount of seepage by electromagnetic flowmeter, by the given instruction of amount of seepage, uses AC frequency conversion speed regulator to regulate the rotating speed of water pump, realizes the adjusting of amount of seepage.
The number that adds amount of seepage, by the fiber of sugarcane divide, daily squeezed quantity determines.The variation that should divide according to a fiber that squeezes sugarcane in season, daily squeezed quantity number and the addition of change infiltration water.Fiber divides when low, and the amount of seepage adding is few, and fiber divides when high, and the amount of seepage adding is many; When daily squeezed quantity is high, the amount of seepage adding is many.When daily squeezed quantity is low, the amount of seepage adding is few.To adding the control of amount of seepage, be according to one, to squeeze the change curve that in season, sugarcane fibre divides to set.
By sugarcane fibre, divide change curve, daily squeezed quantity, the best jointly to form the given instruction of amount of seepage to parameters such as sugarcane compare, the amount of seepage adding is controlled.After comprehensive by dispatch command, electromagnetic flowmeter signal, form frequency converter rotary speed instruction, in order to control infiltration water revolution speed, guarantee that infiltration water supplies with on demand.
Infiltration water temperature control aspect: infiltration water temperature should be controlled between 38～45 ℃, and excess Temperature can make sugarcane layer filament expansion, enters roller difficulty makes the non-sugar in mixed juice increase simultaneously, and purity declines.It is that the quantity delivered of adjusting hot water realizes by detecting infiltration water temperature variation through hot-water valve aperture table that infiltration water temperature is controlled.
System adopts temperature sensor to detect infiltration water temperature, and this detection signal is sent into PLC.PLC receives the instruction from dispatcher or dispatching simultaneously.After dispatch command and temperature detection signal are comprehensive in PLC, form the instruction of hot water control valve opening, regulate infiltration water temperature.
When bagasse moisture on-line is detected: infrared moisture measuring instrument is set after 5# crusher, bagasse moisture is carried out to on-line measurement.And can realize the demonstration of bagasse moisture trend.When bagasse moisture surpasses setting, system sends to operating personnel the signal that transfinites in time, reminds managerial personnel to adjust in time relevant dispatch command or equipment is carried out to necessary adjustment to guarantee the requirement of bagasse water satisfied boiler combustion.Bagasse moisture signal is carried out to the comprehensive rear rate signal that forms squeezer simultaneously.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
