Description
Technical field
The present invention relates to one and monitor decision-making system in real time, particularly relate to recirculated water fouling tendency state and judge system
System.
Background technology
Circulation is widely used in the cooling of central air conditioner system and industrial cooling.Recirculated water was running
Cheng Zhong, along with system temperature rising, evaporation of water and extraneous dust enter the medium factor of water in a large number, causes in system water inorganic
Ion and the enrichment of organic substance, cause in circulation the foulings such as all kinds of heat exchangers, pipeline valve, corrosion and bacterium algae to grow
Raw, and then reduce rate of heat exchange, increasing energy consumption, service life of equipment is shortened in corrosion, jeopardizes production and living safety time serious.
The core of circulating water treatment technology is the water quality such as float, colloid and the solute by effectively controlling in recirculated water
Index comes the dirtiness resistance value of control system, corrosion rate, antibacterial and the breeding of float, improves system and runs cycles of concentration,
Reduce system water supplement amount and blowdown flow rate, and then the treatment operating costs of reduction system, shorten and invest return period, reach energy-conservation and subtract
Row and the target of guarantee public health security.
At present, China's recirculated water mainly uses chemistry method for dosing medicine to process, and throws in chemistry water quality treating chemicals at regular time and quantity, no
Can monitor water quality condition in real time, and then there is control lag, it is impossible to effectively scale inhibition, anticorrosion, concentration rate is low, and energy consumption and water consumption are big
Etc. problem.
Summary of the invention
It is an object of the invention to overcome cycle water in prior art can not monitor water quality condition in real time, and then there is tune
Save delayed problem；The recirculated water fouling tendency state decision-making system solving the problems referred to above is provided.
For reaching above-mentioned purpose, technical scheme is as follows:
Recirculated water fouling tendency state decision-making system, including cooling circulating water system, it is characterised in that described cooling circulating water system
System includes collecting-tank, and the cooling tower that collecting-tank forms closed circuit, and be arranged on the outlet of collecting-tank and cooling tower enters water
Pump between Kou, and the valve being arranged between the water inlet of collecting-tank and the outlet of cooling tower；
Pretreatment system and water quality detection system it is additionally provided with in described collecting-tank；Described pretreatment system is for being arranged on collecting-tank
The filter of outlet position, described water quality detection system includes controller, is connected with controller and is used for detecting filter
And the water quality detecting device of water quality situation between collecting-tank outlet.
Water quality situation is detected in real time by the present invention by water quality detecting device, is then sentenced by testing result
Fixed, because detecting instrument and the detection method of water quality are prior art, therefore repeat no more.The present invention is set by filter
Put, be prevented effectively from suspended solid etc. and the detection of water quality is impacted, improve the accuracy of detection.
Preferably, described water quality detecting device includes total dissolved solid analyzer, water hardness instrument and pH detector.Enter
One step, is provided with temperature inductor in described collecting-tank, described controller is connected with the pump in cooling circulating water system, valve
Connect.The invention provides a kind of water quality detection method, specific as follows:
First according to molten during in the pond detected, temperature, total dissolved solidss, calcium hardness coefficient and basicity factor calculate destination apparatus
The saturated pH and actual pH of liquid, then determines scale coefficient according to saturated PH and actual PH.
Wherein, saturated pH is according to formula pHs=(9.70+A+B)-(C+D) calculates, and actual PH is according to formula pHe=
1.465lgD+4.54 calculates, and scale coefficient is according to formula PSI=2pH-pHeCalculating, in above-mentioned formula, A is total dissolved solidss, B
For temperature in the pipe that detects, C is calcium hardness coefficient, and D is basicity factor, pHsFor saturated pH, pHeIt is fouling for actual pH, PSI
Coefficient.
The scale coefficient PSI determined can correctly reflect aqueous solution fouling and corrosion tendency, and PSI is the biggest, and solution more tends to
In corrosion type, otherwise more trend towards fouling type, in embodiments of the present invention, PSI>6 explanation aqueous solutions be corrosion type, PSI<6 says
Aqueous solution is fouling type, and PSI=6 explanation aqueous solution is leveling style.
In order to be able to reach most preferably filter effect, described collecting-tank includes the pond body with water inlet and outlet, peace
It is contained in the filter base of body interior outlet position, pond, described filter base is additionally provided with sealing member.
Further, described outlet is arranged on body bottom, pond, and this filter base is positioned at this internal outlet of pond
Position, and this filter is arranged on body bottom, pond by this filter base, described water quality detecting device is arranged on pond
The outlet position of body interior.
The present invention compared with prior art, has the following advantages and beneficial effect:
1, water quality situation can be detected in real time by the present invention by water quality detecting device, is then sentenced by testing result
Fixed, it is to avoid chemicals addition control is delayed, reach effective scale inhibition, anticorrosion, reduce the advantage such as energy consumption and water consumption；
2, the present invention setting by filter, is prevented effectively from suspended solid etc. and impacts the detection of water quality, improve detection
Accuracy；
3, present configuration is simple, detection accurately, provide for timely dosing and be effectively ensured.
