Abstract
The invention relates to a cooling circulating water double pollution discharge treatment method, widely applied to water quality treatment and control of cooling circulating water. A control system is utilized to control double pollution discharge of a cooling circulating water treatment system, and a double drain outlet is adopted to carry out water quality control and water quality control. The invention avoids the defect that the traditional water treatment adopts single drain outlet to discharge pollution. By double pollution discharge control technology, stable control and treatment are carried out on circulating water quality indexes, the water quality of circulating water is ensured to be stable for a long time, not only water resource is saved, heat exchange efficiency of equipment is improved, environmental pollution is reduced, but also the service life of cooling circulating water system equipment is prolonged.
Description
Technical field
The present invention relates to the water quality control technology of cooling circulating water system, a kind of cooling circulating water double pollution discharge treatment method of more specifically saying so extensively is useful for the water quality control and the processing of cooling circulating water.
Background technology
At present, circulation is widely used in the productive life every field, and normally moving needs to solve problems such as water quality control, water treatment usually in the use.The normal method for treating water that uses is direct filtration, promptly by suspension in the direct filtered water of various types of filters (as quartz sand filtration device, fibrous nodules fiber bundle filter, all kinds of well strainer), impurity, the control turbidity, adopt physics or chemical method again, water quality is carried out anticorrosion, antiscale and sterilization processing.Though these methods have solved the suspension of system and have suppressed the problems such as fouling, corrosion and bacterium algae of system, but control of the water quality of system and control stability problem are perplexing the development of cool cycles water technology always, as: the impurity blowdown in the water treatment procedure, water quality control blowdown all concentrates on an impurity sewage draining exit of water treatment facilities one filter plant body, the requirement of water amount of blowdown and water quality control simultaneously can't be mated, it is conflicting with Control of Impurities to form water quality control, cause the cooling circulating water system can't be normal, economical, environmental protection, operation efficiently.
Summary of the invention
The present invention will propose a kind of cooling circulating water water quality control processing method exactly, to the stability of circulating water quality control, by double dirt and relevant detection control device, guarantees that circulating water quality can be steady in a long-term in design water quality requirement scope especially.
A kind of cooling circulating water double pollution discharge treatment method is characterized in that by control system the cooling circulating water water treatment system being carried out double pollution discharge control, adopts two sewage draining exits to carry out water quality control and water treatment.
Described control system has water quality parameter detection, water quality blowdown control and filters blowdown control, reaches two blowoff valves by the water quality parameter detecting sensor respectively, carries out water quality control and water treatment to filtering sewage draining exit and water quality sewage draining exit.
The present invention improves existing cool cycles method for treating water, has avoided the drawback of traditional water treatment system single drain outlet blowdown.。Thoroughly solve cooling circulating water water treatment system (adopting two sewage draining exits) to the water quality control of cooling water and the great difficult problem of water treatment.By double dirty control technology, circulating water quality is stablized control and handled, guarantee the circulating water quality long-term stability, both energy savings prolongs service life of cooling circulating water system equipment again.
Description of drawings
Fig. 1 is a schematic flow sheet of the present invention
Fig. 2 is a control signal input and output schematic diagram of the present invention
Below in conjunction with accompanying drawing the present invention is described in further details
The specific embodiment
The present invention can set up controller 1 and water quality sewage draining exit 3 on the filtration system of existing water treatment.Controller 1 has water quality parameter detection, water quality control blowdown and filters blowdown control function, respectively by water quality parameter detecting sensor 6 blowoff valves 2,4, carries out double dirt control to filtering sewage draining exit 5 and water quality sewage draining exit 3.
At first, to the water quality requirement of water in the system and the water quality index of moisturizing, determine the water quality control parameter of cool cycles water running when normally moving by cooling circulating water system.Should control then in the parameter input controller 1, water quality parameter detecting sensor 6 with the water quality parameter of cooling circulating water, be real-time transmitted in the controller and compare.
When the water quality parameter of cooling circulating water surpassed controlling value, controller 1 output signal was opened water quality blowoff valve 2, is carried out low discharge water quality blowdown adjusting by water quality sewage draining exit 3.
When the various types of filtration device of the configuration of cooling circulating water, when the impurity level of holding back filtration surpassed controlling value, controller 1 output signal was opened water filtration blowoff valve 4, filters blowdown by filtering sewage draining exit 5.
When detected water quality parameter reached controlling value, controller 1 output shutdown signal was closed and is filtered blowoff valve 4, stops blowdown, and the benefit entry enters system makes system's water quality turn for the better.
Repeat above-mentioned water quality blowdown adjustment process, the water quality parameter of final control cool cycles is stabilized in the scope of requirement, finish the basic task of cooling system circulation water treatment, promptly effectively control circulating water quality, all the time satisfy in the water quality parameter scope of setting, guarantee water quality with blowdown flow rate, the rate of water make-up of minimum.
Move water quality requirement, configure control parameter (as PH, electrical conductivity, turbidity, chlorion, zeta potential etc.) in advance with moisturizing water quality in controller 1 according to system, water quality parameter detecting sensor 6 is handled the signal input controller 1 that detects.When all kinds of parameters in the system water surpassed setting value, controller 1 was opened water quality blowoff valve 2, carried out water quality control blowdown.
When the various types of filtration device of system configuration was held back the impurity level parameter of filtration above the setup parameter value, controller 1 was opened and is filtered blowoff valve 4, filters blowdown.The benefit of former water has gone into to improve the water quality of water in the system, and when each water quality index of system water all reached setting value, controller 1 cut out blowoff valve, stops the water quality blowdown or filters blowdown.Realize two sewage draining exits are carried out double pollution discharge control by said process, reach control water quality, satisfy recirculating cooling water system water quality and meet standard comprehensively.
Claims (2)
