Shanghai Zhongjing's ultra strong acid and alkali resistant micro nano bubble generator, with its excellent anti-corrosion performance and stable micro nano bubble generation ability, focuses on extreme corrosive environments and extends to multiple fields. Specific application scenarios can be divided into the following categories, covering key areas such as industry, environmental protection, and medical care:

1、 Core application areas: Chemical and Chemical Industry (Strong Corrosive Scenarios)

As the core adaptation scenario of the device, it mainly solves the efficiency and equipment durability issues in the treatment of corrosive liquids such as strong acids, strong alkalis, and high salts, including:

Acid alkali waste liquid pretreatment: In the treatment of strong acid (such as sulfuric acid, hydrochloric acid) and strong alkali (such as sodium hydroxide, potassium hydroxide) waste liquids generated in chemical production (such as electroplating, printing and dyeing, pharmaceutical intermediate synthesis), micro nano bubbles (such as air, ozone bubbles) are used to enhance the oxidation-reduction reaction - for example, ozone micro nano bubbles are used to oxidize heavy metal ions (such as hexavalent chromium) and organic pollutants (such as phenols) in the waste liquid, improving degradation efficiency, while equipment corrosion resistance is avoided from being damaged by waste liquid corrosion.

Chemical reaction assistance: In corrosive reaction processes that require sufficient gas-liquid contact (such as oxidation reactions under acidic conditions and hydrolysis reactions under alkaline conditions), the extremely large specific surface area of micro nano bubbles (hundreds of times larger than ordinary bubbles) can significantly increase the contact area between gases (such as oxygen and carbon dioxide) and liquid reactants, accelerate reaction rates, reduce raw material waste, and the equipment can withstand the strong acid-base environment of the reaction system.

Corrosive liquid stirring and mass transfer: replacing traditional easily corrosive stirring equipment, in chemical storage tanks and reaction vessels, the "non mechanical stirring" mixing of corrosive liquids is achieved through the upward disturbance of micro nano bubbles, while efficient mass transfer of gases (such as inert gas protection and reaction gas introduction) is completed, avoiding mechanical stirring components from failure due to corrosion.

2、 Extended application area one: Environmental protection and sewage treatment (including corrosive wastewater scenarios)

In addition to the chemical industry, it can also treat "weakly to moderately corrosive wastewater" generated by other industries, balancing environmental standards and equipment stability:

Electroplating wastewater treatment: Electroplating industry wastewater often contains acidic plating solution (such as chrome plating wastewater with pH<2), alkaline degreasing wastewater (pH>12), and pollutants such as cyanide and heavy metals. This device can generate ozone micro nano bubbles, which can stably oxidize cyanide in strong acid/strong alkali environments (producing non-toxic CO ₂ and N ₂), or enrich heavy metal ions through the adsorption of micro nano bubbles, improving treatment efficiency.

Garbage leachate treatment: The composition of garbage leachate is complex, and some aged leachate is strongly acidic (pH<3) and contains high concentrations of COD and ammonia nitrogen. Traditional aeration equipment is prone to corrosion. This device can generate air micro nano bubbles to enhance the degradation efficiency of aerobic microorganisms, while the acid and alkali resistant material ensures long-term operation without damage.

Auxiliary desulfurization and denitrification: In the flue gas desulfurization and denitrification systems of power plants and steel plants, the desulfurization solution in the absorption tower (such as weak alkaline limestone slurry or strong alkaline ammonia desulfurization solution) is prone to corrosion of the aeration components. This device can generate micro nano bubbles, improve the contact efficiency between desulfurizer and SO ₂, NOx, and reduce energy consumption.

3、 Extended application area 2: Industrial cleaning (corrosive cleaning scenarios)

In industries that require precise cleaning with acid-base solutions, addressing the dual needs of "cleaning efficiency" and "equipment corrosion resistance":

Semiconductor/Photovoltaic Cleaning: During the cleaning process of semiconductor wafers and photovoltaic silicon wafers, acidic cleaning agents (such as hydrofluoric acid, nitric acid mixture) are often used to remove surface oxide layers and metal impurities, or alkaline cleaning agents (such as ammonium hydroxide solution) are used to remove organic pollutants. This device can generate micro nano bubbles, which adhere to the surface of the wafer and generate a small impact force when they rupture, enhancing the stripping effect of the cleaning agent. At the same time, the equipment is resistant to hydrofluoric acid and strong alkali, avoiding corrosion by the cleaning solution.

Metal surface rust removal/scaling: In mechanical manufacturing and ship maintenance, strong acids (such as hydrochloric acid and phosphoric acid) are used to remove rust on metal surfaces, or strong alkalis are used to remove scale. Micro nano bubbles can enable acid/alkali solutions to cover metal surfaces more evenly, avoiding local excessive corrosion, while improving rust removal/scaling speed and reducing the amount of chemicals used.

4、 Other potential application areas

Medical and Bioengineering: In certain biological reactions that require weak acid-base environments (such as enzymatic hydrolysis and microbial fermentation), this device can generate micro nano oxygen bubbles to improve dissolved oxygen efficiency, and the acid alkali resistant material meets biosafety requirements (food grade/medical grade PP or stainless steel should be selected).

Agriculture and Aquaculture: For the improvement of saline alkali land (soil with strong alkalinity) or the conditioning of acidic soil, this device can generate micro nano bubble water to improve soil permeability; In aquaculture, if the water is weakly acidic/alkaline due to pollution, micro nano oxygen bubbles can be generated to enhance dissolved oxygen, and the equipment is resistant to water corrosion and suitable for long-term outdoor use.
