Through using circulating water management controller, can practice thrift investment cost to cooling tower centralized control, convenient extension is to the control of cooling tower, all water yield, quality of water parameter surveyability, the accurate conveying of measurement.
Description
Technical field
The utility model belongs to the controller field, is specifically related to a kind of recirculated water management controller.
Background technology
The comprehensive physics of cooling-tower circulating water treatment system of existing industrial enterprise and two kinds of treatment process of chemistry comprise a plurality of unit for treating water reactors, as circulation pumping plant, filtration (bypath filter), chemical dosing, heating (nuclear heat) and moisturizing blowdown etc.Because of process distinction relates to a plurality of manufacturers, each processing unit is done things in his own way (as installing respectively, operation, the independent control system) cause system to repeat, loaded down with trivial details, thus cause cost of investment too high, the management poor efficiency, the expense of operation and maintenance is higher, and serious meeting produces operation troubles and production safety accident.
Summary of the invention
The utility model is at existing circular water treating system, and cost of investment is big, the use and maintenance cost height, and managerial confusion and occur the problem of potential safety hazard easily provides the central controlled recirculated water management of a kind of new digitizing controller.
A kind of recirculated water management controller, comprise monitoring water sample transmitter, liquid level sensor, refill flow transmitter and blowdown transmitter, the data that all the sensors reads all are sent on the main frame of recirculated water management controller, and recirculated water management controller also is provided with the multiple power source that is connected with explosive barrel and blowoff gate valve.
By using recirculated water management controller described in the utility model, direct current supply connects, the comprehensive driving, and conductivity sensor is accurately measured, and can reduce medicine consumption, water consumption, and can reduce maintenance cost; Centralized Control is simple to operate, and is powerful, and performance is flexible; Easy expansion is many cooling tower controls; At any time contrast 6 under meters, the total flux in last year and this year, remote keyboard control need not arrived the execute-in-place monitor;
Description of drawings
Accompanying drawing is the synoptic diagram after recirculated water is managed device and cooling tower is connected.
Among the figure:
1. recirculated water management controller, 2. cooling tower, 3. monitoring water sample transmitter, 4. liquid level sensor, 5. refill flow transmitter, 6. blowdown transmitter, 7. strainer, 8. blowoff gate valve, 9. multiple power source.
Embodiment
Below in conjunction with embodiment technical scheme of the present invention is further elaborated.
Embodiment
A kind of recirculated water management controller 1, be provided with four class transmitters on recirculated water management controller 1, this four classes transmitter is respectively the monitoring water sample transmitter 3, the liquid level sensor 4 that is used to monitor explosive barrel inner liquid medicine amount that are used to monitor cooling tower 2 inner liquid medicine amounts, be used to monitor for the refill flow transmitter 5 of refill flow in the cooling tower 2 and be used to monitor the blowdown transmitter 6 of blowdown flow rate.Wherein monitor water sample transmitter 3 and be located on the pipeline of injection threeway of cooling tower 2, and monitoring water sample transmitter 3 comprises conductivity probe, pH value probe and flow interlock switch; Liquid level sensor 4 is provided with in the explosive barrel, according to different needs, liquid level sensor 4 can comprise one or more in Scale inhibitors probe, Biocidal algae-killing agent probe and the soda acid probe, the probe that can certainly comprise all medicaments that other may be used can be monitored 8 different explosive barrels at most simultaneously; Refill flow transmitter 5 is located on the water pipe into cooling tower 2 moisturizings; Blowdown transmitter 6 is arranged on the blow-off pipe that is used to discharge dirt in the cooling tower 2, and is arranged between strainer 7 and the blowoff gate valve 8.More than four class transmitters be used to finish a cooling tower 2 monitored, and this uses novel described recirculated water management controller 1 simultaneously four cooling towers to be monitored, accompanying drawing is depicted as situation about simultaneously two cooling towers being monitored.Recirculated water management controller 1 also is provided with a multiple power source 9, and multiple power source 9 is blowoff gate valve 8 and the motor power supply that is arranged on the explosive barrel.By multiple power source 9, recirculated water management controller 1 can be controlled opening or closing of blowoff gate valve 8, and the amount of liquid medicine that adds to cooling tower.The alarm unit that on recirculated water management controller 1, also is provided with a monitor-interface that can link to each other and is used for reporting to the police with telephone wire or supervisory control computer.Control for convenience, with can be set to 16 recirculated waters when telephone wire or supervisory control computer are connected and manage controllers 1 and be connected with a telephone wire or supervisory control computer.Recirculated water management controller 1 uses be 115 volts direct current as power supply, and all sequence of control uses of recirculated water management controller 1 all is that UNCOL(universal computer oriented language) is write.
The working process of recirculated water management controller 1 is, recirculated water management controller 1 calculates the soup kind that needs add cooling tower 2 automatically according to the data based program that configures in advance that conductivity probe and pH value probe on the monitoring water sample transmitter 3 read, and each kind chemical liquid consumption, and pass through the add-on that multiple power source 9 is controlled soups.And after numerical value that blowdown transmitter 6 reads reached predefined value, recirculated water management controller 1 was opened by multiple power source 9 control blowoff gate valves 8.
By using this to use novel described recirculated water management controller, it is six greatly good to produce The place: 1. the corrosion inhibiting and descaling agent dosage eases down to 21 mg/litre, copper by 30 original mg/litre The material phenomenon no longer takes place to run in heat exchanger, can save cost 30%; 2. only need on-the-spot installation several The platform in-line meter just can be realized the control to a plurality of cooling towers 2; 3. have normal blowdown, dosing, Moisturizing becomes according to water quality finishes above process, and all water yields, water quality parameter are very clear; 4. Electrical conductivity, liquid level sensor, turbine flowmeter are not amplified in the middle of not needing directly into system, accomplish Accurate measurement transmits; 5. system directly is contained in pump house, dustproof, water, magnetic; 6. the operative employee exists Fully skillfully control native system in one week, and can according to the on-the-spot cycles of concentration of moisturizing electrical conductivity, fall Low fouling corrosion speed.
