Summary of the invention
Country handles air-conditioner circulating water and pays much attention to, particularly fatal legionella problem and environmental protection, factor such as energy-conservation,---2003 on August 19,, the Ministry of Health issued that " public place centralized air ventilation system hygienic practice " formulated the strict standard that the central air conditioning water coolant is carried out disinfection, cooling tower is carried out routine cleaning, and domestic general chlorinated product is handled recirculated water, think and can use cheap chlorinated product or the organic biocide of great toxicity, very big to environmental protection and energy saving harm.In actual use, speed is very fast because bacterium develops immunity to drugs, and recirculated water is alkalescence in addition, and the effect of chlorinated product and organic biocide is very little, and effectively kill bacteria and virus also can be brought very big toxicity and corrodibility simultaneously.
The purpose of this utility model just provide a kind of cooling water recirculation system go out give birth to, energy saver, very little with the effect that solves employing chlorinated product that prior art exists and organic biocide, effectively kill bacteria and virus also can be brought very big toxicity and corrosive problem simultaneously.
The technical solution of the utility model is: comprise ozonizer, gas liquid mixer and ozone concn monitor, the ozone gas outlet of described ozonizer is connected with the gas inlet of gas liquid mixer, the outlet of this gas liquid mixer is connected with an outlet of cooling system water tank or the circulating water outlet pipe of this water tank, and the liquid inlet of this gas liquid mixer is connected with another outlet of described water tank; The control end of described ozone concn monitor is connected with ozonizer, the probe of this ozone concn monitor be installed in the described water tank or circulating water loop in the on-line monitoring ozone concn, with the output of control ozonizer.
Described gas liquid mixer comprises ejector and water pump, and the main import of this ejector is connected with the outlet of water pump and the pneumatic outlet of ozonizer respectively with suction port, and the outlet of this ejector is connected with the circulating water outlet pipe of described water tank or this water tank.
Described gas liquid mixer adopts gas-liquid mixing pump.
The outlet of described gas liquid mixer is connected with the circulating water outlet pipe of described water tank and this water tank respectively by T-valve.
The utility model has the advantages that:
A. quantity of wastewater effluent reduces 70%;
B. do not need chemical agent, can satisfy environmental requirement fully;
C. ozone is best biocide, and effectively kill bacteria and virus comprise legionella, removes biological clay, algae, mould etc.;
D. use ozone can reduce erosion rate and (comprise iron and steel and copper) more than 50%;
E. because ozone can effectively be killed biomass, thereby can reduce even remove the dirt on condenser and the interchanger, then use ozone after, the highlyest can save energy 16%, compressor capacity raising 6%;
F. because ozone is on-the-spot the manufacturing, only make electricity consumption and air can realize automatic control, do not need to store and add medicine, but thereby save operation and overhead charges more than 80%;
G utilizes the ozone concn monitor automatically ozone amount to be controlled in the suitable scope.
Below in conjunction with embodiment the utility model is further specified.
Description of drawings
Fig. 1 is an overall structure synoptic diagram of the present utility model;
Embodiment
Referring to Fig. 1, this embodiment comprises ozonizer 1, gas liquid mixer (gas-liquid mixing pump 2) and T-valve 7, the ozone gas outlet of described ozonizer 1 is connected with two of gas-liquid mixing pump 2 corresponding inlets respectively with the water outlet of drawing from water tank 3, the outlet of gas-liquid mixing pump 2, is connected with the inlet of cooling tower 4 behind these circulating water outlet pipe 10 series connection user interchanger 6 in conversion between one of cooling system water tank 3 (bottom of cooling tower 4) inlet 11 and the circulating water outlet pipe 10 by T-valve 7.The working order of the signal control ozonizer 1 of probe 9 outputs of ozone concn monitor 8 is controlled in the suitable scope ozone output of ozonizer 1.
Gas liquid mixer 2 of the present utility model also can be made up of ejector and water pump, the main import of this ejector is connected with the outlet of water pump and the pneumatic outlet of ozonizer 1 respectively with suction port, and the outlet of this ejector is connected with the circulating water outlet pipe 10 of described water tank 4 or this water tank.
Principle of work of the present utility model is:
(1) ozone scale inhibition: the incrustation scale in the recirculating cooling water system is that the formation incrustation scale is separated out in crystallization to salts substances soluble in water owing to continuous evaporation concentration.It is generally acknowledged, ozone does not possess the ability of decomposing incrustation scale, but DOE (USDOE) and NASA (US National Aeronautics and Space Administration) studies show that, ozone has the ability that stops incrustation scale to generate, use ozone, total dissolved solidss in the water can reach 1700mg/l, and hardness can reach 724mg/l (in CACO3) and non-scaling, this be Scale inhibitors commonly used can not compare.Its reason may be that the generation and the ozone of micro-nitric acid has the ability that carbonate is moved to the hydrocarbonate direction.
(2) ozone protection against corrosion: it has been generally acknowledged that ozone is a kind of strong oxidizer; thereby has corrodibility; but research and application show; ozone has non-corrosibility; it is roughly similar to the mechanism of chromate corrosion inhibitors that ozone suppresses Corrosion Mechanism; major cause is owing to after labile atom oxygen that ozone produces after decomposing and the ferrous ion reaction, form the passive film that one deck contains γ-Fe2O3 on anode surface, and metal is had good protective action.NASA studies show that, behind the use ozone, the corrosion speed of iron and steel is 1/2～1/3 of a standard-required in the circulating cooling system.
(3) ozone is killed livestock: ozone is the strongest oxidized form biocide, be the efficient pollution-free biocide of generally acknowledging, more than the concentration of 0.1PPm, get final product effective kill virus and bacterium, and microbial growth in the Control Circulation water effectively, the underdeposit corrosion that alleviates biofouling and cause.Simultaneously, can oxidation scale organic components in the layer matrix, make the dirt layer lose binding agent and fluff and come off, thereby play the effect of scale removal.Ozone is as water conditioner, has simple to operately, and sterilizing ability is strong, and blowdown flow rate is few, can save water and energy, and need not regulate the pH value of water again, does not have advantages such as secondary pollution, and all there is good effect inhibition, the scale inhibition of recirculated water, aspect such as kill livestock.
