The utility model provides a problem that cogeneration circulating water turbidity is big, water waste is big, realized circulating water automatic filtration, it is stable to have maintain the turbidity, reaches the purpose that reduces blowdown, water economy resource.
Description
Technical field
The utility model relates to cogeneration circulating water treatment, is specifically related to a kind of cogeneration recirculated water water saving art Controlling System.
Background technology
When cement kiln residual heat generating cools exhaust steam in steam turbine in process of production, need a large amount of water coolants.For ensureing height of formation vacuum in condenser, the heat transfer effect of condenser must be ensured, maintain the good heat transfer effect of condenser, just must ensure that the heat-transfer surface of condenser is clean without dirt, reduce thermal resistance as much as possible, this just has higher requirement to the Water-quality control of recirculated cooling water, and main Con trolling index has the turbidity of recirculated water, specific conductivity, hardness, basicity etc.Existing water technology in circulating water pool, adds sterilant to suppress the microbial growth in water, the calcium ions and magnesium ions added in Scale inhibitors and recirculated water reacts the carbonate that formed and loosen or the cotton-shaped particle of silicate is separated out, thus the hardness in reduction recirculated water, by technology controlling and process basicity such as acid addings, the control of turbidity controls mainly through blowdown.Because cement production enterprise generally exists a large amount of dust, under normal circumstances, turbidity the most easily exceeds standard, and just needs a large amount of blowdown to change water to reduce the turbidity of water after overproof water quality, and a large amount of pharmaceutical chemicals needing to add of waste, has also consumed water resources excessively simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is a kind of cogeneration recirculated water water saving art Controlling System of design, utilize this system on the basis of original interpolation sterilant, Scale inhibitors Controlling Technology, recirculated water in circulating water cooling tower pond is filtered, reduce the suspended substance in recirculated water, the turbidity of effective reduction recirculated water, be reduced to and control turbidity and the Circulating water effluent that carries out, reduce amount of makeup water, reach the object of water saving.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of cogeneration recirculated water water saving art Controlling System, comprise circulating water cooling tower, the oil cooler be connected with circulating water cooling tower and cooling water circulating pump and condenser, circulating water strainer is established on described circulating water cooling tower side, circulating water strainer position is higher than circulating water cooling tower, circulating water strainer is connected by pipeline with circulating water cooling tower and cooling water circulating pump, the motorized valve controlled by PLC established by the pipeline that circulating water strainer is connected with cooling water circulating pump, circulating water cooling tower establishes turbidimeter.
The utility model adopts the cogeneration recirculated water water saving art Controlling System designed by technique scheme, owing to passing through to increase turbidity on-line measuring point and PLC, water filter on existing circulating water system basis, and relevant connection pipeline and by-pass valve control, achieve recirculated water automatic filtration, maintain turbidity to stablize, reach the object reducing blowdown, saving water resource.
Accompanying drawing explanation
Fig. 1 represents the structural representation of the utility model cogeneration recirculated water water saving art Controlling System.
Embodiment
Illustrate below in conjunction with the structure of accompanying drawing to the utility model cogeneration recirculated water water saving art Controlling System.
See Fig. 1, the utility model cogeneration recirculated water water saving art Controlling System, comprises circulating water cooling tower 1, and the oil cooler 6 be connected with circulating water cooling tower 1 and three cooling water circulating pumps 5 and condenser 7, circulating water cooling tower 1 is also provided with cooling tower fan 8.Circulating water strainer 2 is established on circulating water cooling tower 1 side, wherein, the position of circulating water strainer is higher than circulating water cooling tower 1, circulating water strainer 2 can utilize siphon principle to realize automatic back-washing, namely when recirculated water is filtered by circulating water strainer 2, suspended substance in water is caught by filter material layer and is detained, impurity on filter material layer to a certain extent rear water resistance increases, system can utilize siphon principle to realize automatic back-washing, impurity recoil is got rid of to sewage draining exit, after Impurity removal, water resistance on filter material layer reduces, system has and is automatically converted to filtration condition, the effluent quality of circulating water strainer 2 can maintain about 5NTU.Circulating water strainer 2 is connected by pipeline with the outlet pipe of circulating water cooling tower 1 and cooling water circulating pump 5, the motorized valve 3 controlled by PLC established by the pipeline that circulating water strainer 2 is connected with cooling water circulating pump 5, and motorized valve 3 is used for controlling to go to the water yield of circulating water strainer 2.Circulating water cooling tower 1 is established turbidimeter 4, the online measuring point of turbidimeter 4 is set, the labour intensity in order to reduce watchstander, maintain the water conditioning of recirculated water, realize the automatic control of system, according to the change of turbidity of circulating water, the aperture going to circulating water strainer 2 valve is controlled by transmitter and PLC, adjust the water yield by circulating water strainer 2, make the turbidity of recirculated water remain stable, reach the object reducing blowdown saving water resource.
Process control procedure of the present utility model is: three circulating cooling water pumps 5 supply recirculated cooling water to cooling apparatus oil cooler 6, condenser 7, and the turbidity control criterion of water quality is≤20NTU.When turbidity of circulating water reaches 15NTU, open the valve of motorized valve 3, start to carry out water filtration, the delivery turbidity of circulating water strainer is generally 5NTU, thus the water turbidity in maintenance circulating water pool is between 15-20NTU.When the turbidity of recirculated water reaches 18NTU, the valve of standard-sized sheet motorized valve 3, realizes operating at full capacity of circulating water strainer 2, maintains the running balance of the turbidity of recirculated water.When the turbidity of recirculated water reaches 20NTU, PLC system sends warning automatically.
Before the utility model transformation, the rate of water make-up of circulating water pool every day is at 1800 tons, and blowdown flow rate is every day 550 tons, and all the other be the losses of vaporization losses and drift ice, and the turbidity of recirculated water is wayward, frequently occurs situation about exceeding standard, and causes a large amount of wastes of medicine and water resources.On probation through trial-production, turbidity is controlled by filtration unit after transformation, the blowdown flow rate of recirculated water is down to 250 tons (necessary blowdown reduces the hard and basicity of calcium in recirculated water), rate of water make-up reduces about 300 tons every day, the water quality of annual circulating water pool can be stable control between 15-20, annual water saving about 100,000 tons, reduce by the industrial wastewater discharge of nearly 100,000 tons, economic and social benefit is remarkable simultaneously.This process control system can realize recirculated water automatic filtration, maintains turbidity and stablizes, reduce blowdown, saved water resources.
