Description
Technical Field
The invention relates to a cleaning method and a cleaning agent for a waterway system.
Background
It is known that, in a water passage system for supplying cooling water to an air conditioner, a refrigerator, or a heat exchanger, scale-like chemical scales and suspended minerals are generated as the operation progresses, and such substances adhere to the inside of the water passage system, and various troubles such as local corrosion of a pipe, clogging of the water passage system, a decrease in heat exchange rate, and a rapid increase in pressure loss … … are caused over time.
However, in order to prevent the above-mentioned first kind of trouble from occurring in the water channel system, it has been conventionally adopted to periodically exchange water in the water channel system, clean the interior of the water channel system, and then add a chemical to solve the problem of the scale-like chemical scale and suspended minerals. As the conventional agents, those essentially consisting of organic compounds are used. In the prior art, the water path system needs to be cleaned repeatedly, so that the inconvenience in management is increased, and the consumption of cleaning labor is increased; the chemical agents composed of organic compounds used are highly dangerous and have adverse effects on cleaning workers and the surrounding environment; in this case, if the concentration of the injected chemical is deviated, the pipeline of the waterway system is damaged, and the equipment is lost irreparably.
The above-mentioned disadvantages are the objects of the present invention. That is, not only the problems of the prior art described above are solved, but also various failures in the waterway system are prevented, and the waterway system is managed conveniently, and the worker and the surrounding environment are not contaminated or badly affected, and the waterway system pipe is not damaged. The invention provides a cleaning method for a waterway system and a technical means of a cleaning agent thereof.
Disclosure of Invention
In order to achieve the above object, the present invention adopts the following technical means: the description is made with reference to the figures in the examples, in which:
the cleaning method of the waterway system is characterized in that firstly, 1 or more than 2 water-soluble amorphous blocks, granules or powder containing sodium (Na), silicic acid and further containing silicon (Si), aluminum (Al) and boron (B) are put into water in the waterway system; along with this, water in a water channel system containing 1 or more of charged sodium and charged silicon, charged aluminum and charged boron in the water-soluble amorphous cake, granule or powder is gradually dissolved.
The water-soluble amorphous mass, granule or powder has a composition comprising: sodium oxide Na2O, silicic acid, and SiO2Aluminum oxide Al2O3Boron oxide B2O31 or 2 or more kinds of water path system cleaning agents.
After the technical means is adopted, the cleaning agent containing sodium (Na), silicic acid and 1 or more than 2 of water-soluble amorphous block, granular or powder of silicon (Si), aluminum (Al) and boron (B) in the components is put into water in a water channel system, and simultaneously the water-soluble block, granular or powder contains charged sodium and 1 or more than 1 of charged silicon, charged aluminum and charged boron which are gradually dissolved in the water channel system to clean the interior of the pipeline; at the moment, the charged sodium and water are combined to react to generate sodium hydroxide; the sodium hydroxide combined with the water reaction can dissolve silicon in the scale-shaped chemical dirt, prevent the scale-shaped chemical dirt and suspended mineral substances in a waterway system from occurring in advance, and has the capability ofsoftening and stripping the scale-shaped chemical dirt and suspended mineral substances attached to the waterway system. In addition, the water-soluble amorphous form of the silicic acid component containing silicon, that is, the amorphous form of the inorganic component, promotes the stabilization of the flow in the water channel system, and further works such as softening and peeling of scale-like chemical scales and suspended minerals are performed. Further, the stability can be enhanced by containing an aluminum component. In addition, the charged sodium dissolved in the water reacts with the water to form sodium hydroxide, which is generated and may corrode metals by alkali, and the corrosion is prevented by the boron contained therein.
The cleaning agent for cleaning water channel system is characterized by that the water-soluble amorphous block, granule or powder contains sodium oxide Na2O, silicic acid and SiO2Aluminum oxide Al2O3Boron oxide B2O31 or 2 or more kinds of detergent. This is achieved byThe chemical agent of one composition is an inorganic compound, so that the chemical agent does not cause pollution and adverse effects on operators and the surrounding environment, and does not damage the pipeline of a waterway system.
Examples
Hereinafter, embodiments of the present invention will be described in detail based on the attached drawings:
the water path system cleaning agent of the invention is water-soluble amorphous block, granule or powder containing sodium oxide Na2O, silicic acid and SiO2Aluminum oxide Al2O3Boron oxide B2O3The detergent of (1). When this water-soluble amorphous bulk, granular or powdery detergent is put into water, the water-soluble amorphous bulk, granular or powdery detergent is gradually dissolved, and the charged sodium, charged silicon, charged aluminum and charged boron are gradually eluted. The content of effective element components of the cleaning agent is shown as follows: sodium 7%>13.5 percent, 11 to 18 percent of silicon and 14.3 to 17.2 percent of boron.
However, the water channel system cleaning agent of the present invention can be applied to a water channel system (either a circulating system or a non-circulating system) for supplying cooling water to air conditioning equipment, a refrigerating device or a heat exchanger; the present embodiment is suitable for a cooling device of a cooling tower, as shown in FIG. 1; a cleaning agent is introduced into a water passage system 2 disposed between a cooling tower C and a heat exchanger B.
The water passage system 2 is a portion in which a water discharge portion 4 at the upper portion of the cooling tower C and a water sump portion 5 at the lower portion thereof are connected to each other via a heat exchanger B, and the water discharge mechanism 3 circulates water in the water passage system 2. The cleaning agent 1 is a storage section 6 for storing therein cleaning agents arranged in a mesh shape (with a space) in the storage section 5 (an arrow a indicates a flow direction of air and an arrow W indicates a flow direction of water).
The amount of detergent 1 and the water-soluble amorphous lumps, granules and powders constituting detergent 1 contained in storage section 6 can be adjusted to 0.0025% to 0.003% in water depending on the flow rate of water flowing through water passage system 2 between cooling tower C and heat exchanger B, and detergent 1 can exert the maximum effect.
Next, the water-soluble amorphous cake, granule, and powder of cleaning agent 1 disposed in storage section 5 are gradually dissolved in water in the water channel system, and charged sodium, charged silicon, charged aluminum, and charged boron contained in the water-soluble amorphous cake, granule, and powder are also gradually eluted. Wherein, due to the movement of the charged sodium, the scale-shaped chemical dirt and the suspended mineral in the waterway system are prevented from being generated in advance, and the scale-shaped chemical dirt and the suspended mineral in the attached waterway system are softened and peeled.
Further, a description will be given of a process of removing scale-like chemical scales in a water channel system by detergent 1 dissolved in water in the water channel system and by chemical decomposition of the scale-like chemical scales due to movement of charged sodium.
First, scaly chemical foulants generated in heat exchangers and pipes are mainly composed of elements such as silicon (Si), calcium (Ca), magnesium (Mg), iron (Fe), and the like. On one hand, because the water-soluble amorphous block, granule or powder is dissolved in the water channel system, the sodium (Na) dissolved in the water and the water are combined and reacted into sodium hydroxide (2NaOH), and the sodium hydroxide can dissolve silicon (Si) in the scale-shaped chemical dirt.
Chemical structure 1
Silicon (Si) having an adhesive effect in the scale-like chemical dirt component is dissolved in water, and other components such as calcium (Ca) in the scale-like chemical dirt are also dropped in water. At this time, sodium hydroxide is not dissolved in calcium (Ca), magnesium (Mg) and the like, and fine crystals are formed and flowed into water. The scale-like chemical scales generated in the heat exchanger and the piping can be removed by such dissolution.
There are other methods of dissolving charged sodium in water, such as making into troche and concentrated granule, but since lactose and acid clay which are not resistant to high temperature are used, it is not suitable to use high temperature fluid. The invention adopts inorganic components, and uses the method that the temperature is not moved left and right, but the components are dissolved in water stably for a long time, and uses silicic acid to prepare amorphous (noncrystalline) shape; at this time, the aluminum (hydroxide) is added, and the dissolution is stabilized (aluminum silicate).
Next, the following description is made: suspended minerals are produced in the pipe and heat exchanger from the sticky state of fungi together with the formation of scaly chemical scales, which are peeled off and suspended substances are also dropped off. This phenomenon can remove scaly chemical scales and suspended minerals without using boron (B), but when sodium hydroxide is produced, there is a possibility that metals are corroded by alkali; in order to prevent this corrosion, boron should be added, i.e. charged boron forms a charged boron film on the inner side of the pipe or heat exchanger, so that the metal is not corroded and has a protective effect.
The principle process of removing scaly chemical dirt and suspended minerals generated in the pipeline system is described above. Next, sodium hydroxide, which is a combination reaction of sodium (Na) and water, reacts to a scaly chemical scale component contained in water as described below to prevent the formation of new scaly chemical scales. That is, the main component of scale-like chemical scales contained in water is composed of elements such as calcium (Ca) and magnesium (Mg), and these various inorganic elements are dissolved in water after being bonded with carbonic acid, hydrogen, and the like. Sodium hydroxide reacts with calcium and magnesium in water to aggregate, so that no new scaly chemical scale is formed in the water channel system (pipeline and heat exchanger), but the water channel system is coagulated into gel and finally discharged as slurry.
The above description shows that the cleaning agent of the present invention is composed of safe inorganic elements, and is very convenient in storage, use, transportation, etc.
The results of the effectiveness test of the cleaning agent for waterway system according to the present invention are illustrated in fig. 2: this test was conducted by charging 5Kg of the detergent of the present invention into a cooling apparatus of 175t, and then measuring the pressure difference between the inlet side and the outlet side of the heat exchanger, and is illustrated by referring to FIG. 2.
According to the graph represented in fig. 2, the pressure loss value decreases with the passage of time for the curve using the detergent of the invention, and after 3 months, the value shows stability. This represents a profile of detergent with an increase in pressure loss over time, indicating the occurrence of scale-like chemical scales, suspended minerals within the water system. This indicates that scaly chemical fouling, suspended minerals are occurring and adhering within the waterway system.
From the above test results, it can be proved that the cleaning agent of the present invention has a good cleaning effect when used in a waterway system.
As described above, the cleaning agent of the present invention is capable of removing scale-like chemical scales and suspended minerals adhering to a water channel system constantly and continuously during administration, and management of the water channel system is facilitated. Meanwhile, new scaly chemical dirt and suspended mineral substances are prevented from being attached to the waterway system, and the heat transfer efficiency can be improved along with the reduction of the pressure loss of the waterway system.
Further, the cleaning agent of the present invention contains 1 or 2 or more components selected from among charged sodium, charged silicon, charged aluminum and charged boron in an amorphous cake, a granular or a powder. Since this material is an inorganic compound, it does not adversely affect the operator and the surrounding environment, and there is no fear of damaging the piping of the waterway system.
