Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.Following examples will contribute to those skilled in the art and understand the present invention further, but not limit the present invention in any form.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, some changes and improvements can also be made.These all belong to protection scope of the present invention.
The present invention adopts double indexing to control water quality, and namely specific conductivity controls and chlorion control.This two parameter arbitrary parameter does not meet user's set(ting)value, then native system can be intervened automatically to system, and index is returned in user's range of set value.Meanwhile native system also will carry out Automatic Dosing according to actual blowdown flow rate to system.
As shown in Figure 1, water treatment system of the present invention, comprises pollution discharge mechanism 7, medicating mechanism 2 and Programmable logical controller cabinet 3.Programmable logical controller cabinet 3 is with enough analog quantitys/number connect test port, relevant device is controlled with the signal of field apparatus in acquisition system (wash water valve, water pump, electric switching valve etc.), and on-the-spot hand/automatic switchover can be carried out to the blowdown motorized valve of pollution discharge mechanism 7 and medicating mechanism 2, and on-site manual control is carried out to the blowdown motorized valve of pollution discharge mechanism 7 and medicating mechanism 2.
First the original parameter of Programmable logical controller cabinet 3 is set, then by Data Control ratio adjusting valve 6 aperture, the control of sewage disposal speed of Programmable logical controller cabinet 3 according to cycles of concentration or conductivity probe 4, control medicating mechanism 2 start and stop dosing pump according to cycles of concentration simultaneously.According to different water coolant medicaments, dosing method need be set.As slow-release scale inhibitor dosage control according to system blowdown flow rate, sterilant dosage controls according to systemic circulation amount.Without people for removing start stop operation, according to different medicaments, automatically carry out dosing work, chemical feeding quantity is more reasonable, and water-quality guideline is stablized.
Original parameter generally comprises: cycles of concentration, specific conductivity, dosing pump, chlorine ion concentration and chemical feeding quantity per hour.
Specific conductivity controls, and mainly through the difference of contrast electrical conductivity ratio (ratios of two conductivity probe 4 image data) with user's set(ting)value, controls blowdown motorized valve.When the electrical conductivity ratio in pond of cooling tower 1 is lower than user set(ting)value A (set(ting)value is A, B two grades), system is automatically opened wash water valve and is carried out blowdown operation, when electrical conductivity ratio reaches the value B of setting, Programmable logical controller cabinet 3 control of sewage disposal mechanism 7 automatically closes wash water valve and stops blowdown operation.By touch-screen or upper computer (computer), valve opening amount or flux values are set in detail.
Chlorion controls, and mainly through the difference of the contrast chlorion ratio ratio of 9 image data (two chlorions pop one's head in) with user's set(ting)value, controls blowdown motorized valve.When the chlorion ratio in pond of cooling tower 1 is lower than set(ting)value A (set(ting)value is A, B two grades), Programmable logical controller cabinet 3 control of sewage disposal mechanism 7 automatically opens wash water valve and carries out blowdown operation, when chlorion ratio reaches the value B of setting, Programmable logical controller cabinet 3 control of sewage disposal mechanism 7 automatically closes wash water valve and stops blowdown operation.By touch-screen or upper computer (computer), valve opening amount or flux values are set in detail.
Cycles of concentration controls (cycles of concentration=rate of water make-up/blowdown flow rate), and rate of water make-up is monitored by feed water flow gauge 8, blowdown flow rate is monitored by electromagnetic type blowdown flow meter 5.Mainly through contrasting the difference of cycles of concentration instantaneous value and set(ting)value, blowdown motorized valve is controlled.When cycles of concentration ratio is lower than user set(ting)value A (set(ting)value is A, B two grades), Programmable logical controller cabinet 3 control of sewage disposal mechanism 7 automatically opens wash water valve and carries out blowdown operation, when cycles of concentration ratio reaches user set(ting)value B, Programmable logical controller cabinet 3 control of sewage disposal mechanism 7 automatically closes wash water valve and stops blowdown operation.By touch-screen or upper computer (computer), valve opening amount or flux values are set in detail.In addition, the automatic makeup water yield of pond of cooling tower 1 when needing automatic shield to start shooting during system boot, the shielding time freely should be changed by user.
Medicating mechanism 2 controls, and by monitoring in real time the aggregate-value of blowdown flow rate, Programmable logical controller cabinet 3 controls medicating mechanism 2 (dry contact control) automatically.When the aggregate-value of blowdown flow rate often expires X ton hour, Programmable logical controller cabinet 3, automatically unlatching medicating mechanism 2 pairs of pond of cooling tower 1 carry out dosing X minute.By that analogy blowdown flow rate often completely X ton then carry out a dosing.By touch-screen or upper computer (computer), the administration timing of drug of medicating mechanism 2 during unit blowdown flow rate is set in detail.
Control for daily blowdown, when cooling-water pump runs, dry contact closes, and pollution discharge mechanism 7 allows to start and automatically opens blowdown motorized valve and carries out daily blowdown control, and when cooling-water pump is out of service, no matter conductivity value is in what scope, and rapid pollution discharging is closed.By touch-screen or upper computer (computer), daily sewage draining valve open amount or flux values are set in detail.
Field programmable logic housing 3 is connected with cold monitoring upper computer and transmits, the data such as system blowdown flow rate, specific conductivity, cycles of concentration, chemical feeding quantity are imported in monitoring upper computer (computer).Further, monitoring computer can be selected, to cycles of concentration or specific conductivity upper lower limit value, to blowdown valve of electric valve aperture, set parameters such as administration timing of drug water coolant pollution discharge mechanism 7, medicating mechanism 2 control mode.Can monitor in time system blowdown, dosing situation, log history data, and adjust in time, guarantee that water-quality guideline is stablized, automatic pollution discharge, Adding medicine control are normal.
Above specific embodiments of the invention are described.It is to be appreciated that the present invention is not limited to above-mentioned particular implementation, those skilled in the art can make a variety of changes within the scope of the claims or revise, and this does not affect flesh and blood of the present invention.When not conflicting, the feature in the embodiment of the application and embodiment can combine arbitrarily mutually.
