Abstract
The utility model relates to an online automatic control system for decolorizing sewage by adopting ozone. The online automatic control system comprises an ozone generator, a chromaticity measuring device and a PID (photo-ionization detector) controller, wherein the chromaticity measuring device is in circuit connection with the PID controller and the ozone generator through a current converter; the PID controller controls the output power of the ozone generator according to signals input by the chromaticity measuring device. Compared with the prior art, the online automatic control system disclosed by the utility model adopts the chromaticity measuring device and the PID controller to automatically adjust the power of the ozone generator so as to achieve an aim of automatically controlling the output of ozone; according to the chromaticity and flow changes of the sewage, the output of ozone is controlled in real time, so that the treatment effect of the sewage can reach a standard. The online automatic control system disclosed by the utility model reduces the secondary pollution caused by redundant ozone, saves energy sources, and is convenient in control and safe and reliable in use.
Description
Technical field
The utility model relates to technical field of sewage, and especially a kind of on-line automatic Controlling System that adopts ozone that sewage is decoloured and processed, is widely used in the fields such as sewage disposal and middle water reuse.
Background technology
Sewage disposal comprises the processing of municipal effluent, industrial sewage and medical sewage, and ozone application is sterilization and disinfection, removes pollution substance at the Main Function of waste water control industry; Especially decolouring taste removal is had to irreplaceable effect, to reach emission standard.
Existing ozone decolours while processing to sewage, and because the colourity of sewage and flow etc. can change, and the supply of ozone can not change and change along with their, causes and deepens or when the discharge of sewage increases, its treatment effect can not be up to standard when Colority of Sewage Water; And shoal or when flow reduces, can produce again unnecessary ozone when Colority of Sewage Water, not only to environment, bring secondary pollution, and can bring the waste of the energy.
Utility model content
For above the deficiencies in the prior art, the purpose of this utility model is to provide a kind of on-line automatic Controlling System that adopts ozone that sewage is decoloured and processed, adopt online colour measurement device to measure in real time ozonize effect, automatically control the power of ozonizer, to reach the object of automatic control ozone output.
The purpose of this utility model is achieved by the following technical solution:
The on-line automatic Controlling System that adopts ozone that sewage is decoloured and processed, comprise ozonizer, colour measurement device and control device, described ozonizer is connected with control device circuit, control device is connected with described colour measurement device circuit, described control device, according to the signal of colour measurement device input, is controlled the output rating of ozonizer.
As optimal technical scheme of the present utility model, described control device comprises PID controller, and described colour measurement device is connected with PID controller circuitry by current converter.
As optimal technical scheme of the present utility model, described current converter is 4-20mA transmodulator.
As optimal technical scheme of the present utility model, described colour measurement device and described current converter are arranged in an airtight cabinet.
As optimal technical scheme of the present utility model, described colour measurement device is arranged on the water port place of sewage.
The beneficial effects of the utility model are: with respect to prior art, the utility model adopts colour measurement device and PID controller to automatically adjust to the power of ozonizer, reaches the object of automatic control ozone output; According to the variation of Colority of Sewage Water and flow, control in real time ozone output, thereby can make the treatment effect of sewage up to standard.The utility model had both reduced the secondary pollution that unnecessary ozone brings, and had saved again the energy, and it is convenient, safe and reliable to control.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
Fig. 1 is automatic control system FB(flow block) of the present utility model.
In figure, 1, water port, 2, colour measurement device, 3, current converter, 4, PID two-position controller, 5, control circuit for ozone generator, 6, Discharge Cell of Ozone Generators.
Embodiment
As shown in Figure 1, the on-line automatic Controlling System that adopts ozone that sewage is decoloured and processed, comprise ozonizer, colour measurement device 2,4-20mA current converter 3 and PID two-position controller 4, colour measurement device 2 and 4-20mA current converter 3 are arranged in an airtight cabinet, described colour measurement device 2 is arranged on water port 1 place of sewage, colour measurement device 2 is connected with PID controller 4 circuit by current converter 3, and described current converter 3 is that outward current is the transmodulator of 4-20mA.PID controller 4 is connected with Discharge Cell of Ozone Generators 6 circuit by control circuit for ozone generator 5, and PID controller 4, according to the signal of colour measurement device 2 inputs, is realized the online output rating of automatically controlling in real time ozonizer.
During use, first setup control numerical value in PID controller 4, outputs control signals to ozonizer.When Colority of Sewage Water improves or when flow becomes large, online colorimetric detection signal changes thereupon, 4-20mA current signal is linear change thereupon also, by PID controller 4, make ozonizer increase or reduce power, thereby guarantee appropriate ozone work output, ozone is played a role more accurately in sewage decoloring field, avoid secondary pollution.
Claims (5)
1. an on-line automatic Controlling System that adopts ozone that sewage is decoloured and processed, comprise ozonizer, colour measurement device and control device, it is characterized in that: described ozonizer is connected with control device circuit, control device is connected with described colour measurement device circuit, described control device, according to the signal of colour measurement device input, is controlled the output rating of ozonizer.
