Background technology
Along with the raising of living standards of the people, require also corresponding raising for drinking water quality.Country forces the implementation of standard for city quality processed, and this control for waterworks dispensing (such as throwing alum) technology is had higher requirement.The greatest problem of Artificial Control existence at present is: exceed standard in order to prevent water turbidity, add alum as far as possible; And when condition changes, manually can not adjust throwing the alum amount constantly, produce to consume and also just can't reduce; In the face of accident, careless slightly, just be easy to generate industrial accident, jeopardize safe drinking water.
It is the Industrial processes of a complexity that tap water is thrown alum technology, and it has non-linear, large time delay, many enter factors (flooding velocity, influent turbidity and temperature, pH value, alum concentration etc.), characteristics such as uncertainty, time variation, ambiguity and the individual opposite sex.It still is an open system, and except limited several the survey the parameter, many immesurable factors also can directly influence throws the alum effect, causes this critical process still to be under manually operated, the relatively backward state.
At present, domestic most water factories mostly adopt volume pump to throw the alum flow control, with the frequency of volume pump and the stroke indirect control parameter as the alum flow control.But survey factually, have severe nonlinear between the frequency of volume pump and stroke and the theoretical delivery, after the barrier film deterioration of volume pump, flow also will reduce greatly, jeopardize production safety.Volume pump has also exposed its deficiency in the process of long-time running, as equipment and supplies costliness, maintenance technique require high, installation space is big, therefore Stroke Control must be difficult to realize automatization, Small Flow Control difficulty etc. at the scene.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of dispensing Controlling System is provided, having solved tap water production dispensing technology lags behind, cycle is long, and multiplefactor is disturbed, the difficult problem of automation fields such as nonlinearities change, realized tap water production throwing alum technology unmanned, automatically operation is safe and reliable, the intelligent control target of water conditioning.
For realizing above-mentioned technical purpose, the scheme that the utility model provides is: a kind of dispensing Controlling System, comprise source water turbidity instrument, source water temperature sensor, the preceding water turbidity instrument of filter and medicine under meter, and, the signal output part of water turbidity instrument and medicine under meter connects with the PLC module respectively before described source water turbidity instrument, source water temperature sensor, source water ga(u)ge, the filter, and the PLC module connects the electronic control valve on the administration line set respectively and drives the frequency transformer of the impeller pump work on the administration line set.
And the signal that water turbidity instrument, medicine under meter, electronic control valve and frequency transformer connect with the PLC module before described source water turbidity instrument, source water temperature sensor, source water ga(u)ge, the filter is the 4-20MA signal.
And described PLC module connects with the upper computer computer.
And described upper computer computer expert crosses Ethernet switch and connects with the PLC module.
And described Ethernet switch changes ethernet server by serial ports and connects with the source water ga(u)ge.
And described serial ports changes ethernet server and the source water ga(u)ge carries out the RS485 communication by the Modbus agreement.
The utility model a plurality of with rivers be the water factory at water source realized tap water production throw alum technology automatically operation reach best effect, guaranteed that the waterworks realizes energy-saving and cost-reducing, personnel reduction and enlargement and production safety, its economic and social benefit is all very remarkable, is convenient to promote in various waterworkss.Be to carry out the strong behave that national water and wastewater industry is forced standard, guaranteed urban and rural residents' drinking water safety, utilize modern information technologies to rebuild traditional industry, promote technical progress of industry.
