Description
Technical Field
The invention belongs to the technical field of cleaning agents, and particularly relates to a dust accumulation acidic cleaning agent and application thereof.
Background
The power generation efficiency of the photovoltaic panel is significantly affected by the ash deposition phenomenon, which is a problem that cannot be ignored. To address this challenge, photovoltaic power plants commonly employ cleaning robots or manual methods for periodic ash removal. In non-factory areas, the photovoltaic panel ash deposition caused by natural sedimentation is usually loose, and can be easily removed by simple blowing or water washing.
However, the dust retention challenges faced by photovoltaic panels on or near the roof of a factory are particularly unique and complex. This is mainly due to the specific environmental contaminants generated by industrial production activities, which are more adherent and aggressive to the photovoltaic panels. Specifically, these contaminants include soot, metals and metal oxides, polycyclic aromatic hydrocarbons, oils and fats, and fibers, among others, are of a wide variety and complexity. They not only gradually absorb dust in the air to form a crystalline shell, but also tend to have strong adhesion, high hardness, and tightly adhere to the surface of the photovoltaic panel, and are difficult to remove by conventional physical ash removal means.
Even more troublesome is that for some long-term unwashed factory floor photovoltaic panels, the contaminants may be further solidified after the microorganisms carried on the dust are rain washed. During the growth of microorganisms they secrete mildew spots containing enzymes and organic acids which, when combined with contaminants, form stubborn dust which is difficult to remove by purging or water flushing. The dense and uneven dust accumulation not only can reduce the power generation efficiency of the photovoltaic panel, but also can generate a hot spot effect, damage the photovoltaic panel and even cause potential safety hazards such as fire disaster.
In addition, the heavy and light plant areas are different in production type, and pollution sources are different. This results in different types of plant area photovoltaic panel dust deposition components and characteristics, further increasing the difficulty and complexity of the ash removal. Therefore, it is important to develop a high-efficiency cleaning agent for the dust accumulation of the photovoltaic panels in different types of factories.
Although the types of toughened glass cleaning agents on the market are numerous, few products which can be effectively applied to the intractable dust collection cleaning of the photovoltaic panels in factories are available. Moreover, most cleaning agents are neutral or alkaline, which can corrode the glass and cause damage to the photovoltaic panel. Therefore, the development of the high-efficiency acidic chemical cleaning agent specially designed for the roof photovoltaic panel in the factory area has important significance. The cleaning agent needs to be capable of removing stubborn dust in a targeted manner, and meanwhile, protecting the photovoltaic panel from damage so as to ensure efficient operation of the photovoltaic system and improve the power generation efficiency. This not only helps to promote the economic benefits of the photovoltaic power plant, but also helps to promote the sustainable development of renewable energy sources.

In the specific embodiment, the residence time of the dust-accumulation acidic cleaning agent on the surface of the photovoltaic panel is 10-60 s, the washing times are 1-2 times, and the dosage ratio of the water to the dust-accumulation acidic cleaning agent is (1-2): 1.
Compared with the prior art, the invention has the following beneficial effects:
The invention provides a dust accumulation acidic cleaning agent, which comprises sulfamic acid, an alkaline pH regulator, an anionic surfactant and a foaming agent, wherein sulfamic acid can react with metal and metal oxide, has extremely strong calcium scale removal capability, can increase the cleaning capability of the metal oxide, and has extremely good removal effect on specific metal dust, carbonate and silicate particles in a factory area. The aqueous solution of the alkaline pH regulator is alkaline, so that the pH value of the cleaning agent can be effectively regulated, and the alkaline pH regulator is stabilized in the optimal pH use range of several anionic surfactants in the components, thereby improving the stability and the acid cleaning effect of each component. The anionic surfactant has excellent emulsifying, solubilizing, decontaminating, dispersing, cleaning, wetting, antistatic and antirust properties, is suitable for compatibility with other components of the acidic cleaning agent, and can meet the cleaning requirements of most factory scenes. The foaming agent has good stability, can play a role in foaming in the cleaning agent, and is beneficial to improving the cleaning effect. In conclusion, the components of the dust accumulation acidic cleaning agent cooperate to jointly improve the cleaning effect, stability and applicability of the cleaning agent. In addition, the acidic cleaner can treat inorganic dirt which is difficult to remove by the alkaline cleaner.
Furthermore, the dust acidic cleaning agent also comprises acetone, sodium chloride and IS-129 hydrochloric acid corrosion inhibitor, and IS suitable for cleaning dust of photovoltaic panels in heavy factories. The dust accumulation components of the photovoltaic panel in the heavy factory area are complex, and the dust accumulation components comprise metal oxides, carbonates, silicate, residual organic matters of incomplete combustion of coal dust, polycyclic aromatic hydrocarbon, fly ash and the like. Wherein, polycyclic aromatic hydrocarbon in the dust as an organic matter has hydrophobicity, and the hydrophobicity is gradually enhanced along with the increase of the ring number of the benzene ring. The cleaning agent composed of sulfamic acid, alkaline pH regulator, anionic surfactant and foaming agent can be used for removing the dust, but when acetone and sodium chloride are added on the basis of the cleaning agent, naCl reacts with sulfamic acid to generate hydrochloric acid, so that the reactivity of the cleaning agent to metal and oxide dust IS enhanced, the acetone IS used as an organic solvent, has fat solubility and water solubility, can effectively dissolve and remove various organic matters and adhesive matters on the surface of the photovoltaic panel, and the IS-129 hydrochloric acid corrosion inhibitor plays a role in avoiding the corrosion of the frame of the photovoltaic panel, so that the cleaning effect can be further improved.
Furthermore, the dust-accumulation acidic cleaning agent also comprises ammonium citrate and laurinol polyoxyethylene ether, and is suitable for dust-accumulation cleaning of photovoltaic panels in light factories. Because the organic matters in the dust accumulation of the photovoltaic panel in the light factory area are less, various fiber filaments, saw dust and the like are easy to fly and are adsorbed by the dust, so the ammonium citrate and the laurinol polyoxyethylene ether are added into the cleaning agent. The ammonium citrate has the effects of both the detergent and the permeation promoter, can reduce the diffusion resistance of the cleaning agent between fibers and reduce the adsorption of the cleaning agent on grease, and simultaneously, the laurinol polyoxyethylene ether is used as an antistatic agent, so that the electrostatic effect of the fibers can be further reduced. When the cleaning agent composed of sulfamic acid, alkaline pH regulator, anionic surfactant and foaming agent and the added ammonium citrate and laurinol polyoxyethylene ether are used simultaneously, the cleaning effect on dust deposit adhered to various fibers can be remarkably improved.

The pH value of the dust accumulation acidic cleaning agent is 2.5-4.0, the sulfamic acid cleaning effect is optimal in the pH range of 2.5-4.0, and the stability of the rest components can be maintained.
On the one hand, acetone, sodium chloride and IS-129 hydrochloric acid corrosion inhibitor are added on the basis of the dust-accumulation acidic cleaning agent, and the dust-accumulation acidic cleaning agent specifically comprises 1.0% -6.0% of sulfamic acid, 0.5% -4.0% of alkaline pH regulator, 1.0% -4.0% of anionic surfactant, 0.3% -0.5% of foaming agent, 1.0% -4.0% of acetone, 0.5% -1.0% of sodium chloride, 0.05% -0.1% of IS-129 hydrochloric acid corrosion inhibitor and the balance of desalted water. Wherein, 1.0 to 4.0 percent of acetone, 0.5 to 1.0 percent of sodium chloride and 0.05 to 0.1 percent of IS-129 hydrochloride corrosion inhibitor are simply called as a component B in the following formula.
On the one hand, ammonium citrate and laureth are added on the basis of the dust accumulation acidic cleaning agent, and the dust accumulation acidic cleaning agent specifically comprises 1.0% -6.0% of sulfamic acid, 0.5% -4.0% of alkaline pH regulator, 1.0% -4.0% of anionic surfactant, 0.3% -0.5% of foaming agent, 0.5% -4.0% of ammonium citrate, 1.0% -2.0% of laureth and the balance of desalted water. Wherein, in the following formula, 0.5 to 4.0 percent of ammonium citrate and 1.0 to 2.0 percent of polyoxyethylene lauryl ether are abbreviated as component C.
In one embodiment, the alkaline pH regulator is one of disodium hydrogen phosphate or sodium citrate, and the anionic surfactant can be one or more of monolauryl phosphate, dodecylbenzene sulfonic acid and alcohol ether phosphate surfactants. In addition, the foaming agent is preferably dinitroso pentamethylene tetramine foaming agent.

The invention further provides application of the dust accumulation acidic cleaning agent in cleaning of photovoltaic panels in factories.
Furthermore, for heavy factory areas such as coal-fired power plants, coking plants, steel plants, chemical plants, printing and dyeing plants and the like, the cleaning agent should be an acidic cleaning agent for accumulated dust formed by the component A and the component B.

In the dust accumulation acidic cleaning agent composed of the component A and the component B, 1) polycyclic aromatic hydrocarbon is taken as an organic matter, has certain hydrophobicity, and the hydrophobicity is gradually enhanced along with the increase of the ring number of benzene rings, so that certain difficulty is brought to cleaning the dust accumulation by only adopting the component A, and hydrochloric acid is generated by the simultaneous use of NaCl and sulfamic acid when the component A+the component B is adopted, so that the reactivity of the dust accumulation on metals and oxides thereof is increased. 2) Acetone is used as a fat-soluble and water-soluble organic solvent, and can dissolve various organic matters and adhesives adsorbed on the surface of the photovoltaic panel to desorb the organic matters and adhesives, and then quickly volatilize to enable the organic matters and adhesives to be adsorbed again by dust and finally removed.
Furthermore, for light industrial areas such as textile factories, building material factories, food factories and the like, the cleaning agent should use the dust-accumulation acidic cleaning agent composed of the component A and the component C. The dust accumulation component of the photovoltaic panel in the factory has fewer organic matters, and various fiber filaments, saw dust and the like are easy to fly away and are adsorbed by dust after rain and adhered to the photovoltaic panel. It is desirable to add component C, which contains a penetration aid and an antistatic agent, to facilitate removal of various types of fibers that are prone to static electricity generation.
In the dust accumulation acidic cleaning agent composed of the component A and the component C, 1) various fibers are easy to generate static electricity due to the effects of factors such as electric field induction and hot air drying, and ammonium citrate has the effects of a detergent and a permeation assisting agent, so that the diffusion resistance of the cleaning agent components among the fibers is reduced, the adsorption of the cleaning agent components on grease is reduced, and 2) laurinol polyoxyethylene ether (peregal O) is used as a nonionic surfactant, is acid and alkali resistant, so that the static effect of the fibers can be further lightened, and the cleaning effect of dust accumulation adhered to various fibers is improved when the component A+the component C is adopted.
For other types of less polluting plant areas, the cleaning agent is only a dust-accumulation acidic cleaning agent composed of the component A.
In the dust accumulation acidic cleaning agent formed by the component A, 1) sulfamic acid can react with metal and metal oxide, has extremely strong calcium scale removal capability, can increase the cleaning capability of the metal oxide, has extremely good removal effect on metal dust, carbonate and silicate particles which are special in a factory area, 2) an alkaline pH regulator (disodium hydrogen phosphate and sodium citrate aqueous solution) is alkaline, has the effect of regulating pH, can stabilize the pH value of the cleaning agent to be 2.5-4.0, and the optimal pH ranges of several anionic surfactants in the component are all 2.5-4.0, so that the stability of each component can be improved, and the acid cleaning effect is improved, and 3) the anionic surfactant is widely applied surfactant and is suitable for compatibility with other components of the acidic cleaning agent. The monolauryl phosphate surfactant has excellent emulsifying, solubilizing, antistatic and antirust performances, and the alcohol ether phosphate surfactant has excellent decontamination, emulsifying, dispersing, cleaning, wetting, antistatic and antirust performances, and is suitable for most factory scenes. 4) Dinitroso pentamethylene tetramine plays a role in foaming and has good stability.
