Hydrogen peroxide is also known as hydrogen peroxide. Pure hydrogen peroxide is a light blue viscous liquid. It can be mixed with water in any proportion. It is a strong oxidant. It is suitable for disinfection of medical wounds, environmental impact disinfection and food safety disinfection in my country. . Wuxi hydrogen peroxide with higher concentration (more than 10%) is used in textile, leather, paper, and wood manufacturing industries as bleaching and deodorizing agents. Hydrogen peroxide is also one of the components of hair dyes, and is also used as a material for synthesizing organic raw materials (catechol), medicine, metal surface treatment agent, polymerization initiator, etc. Can also be used as rocket propellant. Hydrogen peroxide manufacturers are mainly used for sterilization and external medical purposes, such as wound disinfection. The best ratio for testing blood: 6% hydrogen peroxide plus 0.005% methylene blue. Industrial hydrogen peroxide is another hydrogen oxide besides water. The viscosity is slightly higher than that of water, and the chemical properties are unstable. Generally, it is stored in the form of a 30% or 60% aqueous solution, and its aqueous solution is commonly known as hydrogen peroxide. Hydrogen peroxide has strong oxidizing properties and is weakly acidic. There is an oxidative technical role and a reduction historical role in the presence of different developmental situations. It is used for photographic stain remover, blue thinning of color film positive film, thin film super-proportion, etc. It is easy to decompose and not easy to survive for a long time.

Anthraquinone method is one of the most mature production methods in the world. At present, the methods for producing hydrogen peroxide by anthraquinone method in domestic industry include nickel catalyst in suspension kettle, palladium catalyst in fixed bed, fluidized bed process and so on.

In the production process of different processes, a large number of filters and detergents are used in order to solve the problems of process medium pollution, product output increase, energy consumption reduction, safety production guarantee and environmental protection.

The development process of filtration technology separation in the production of anthraquinone mainly involves various teaching forms such as liquid-solid separation, liquid-liquid separation, gas-solid/gas-liquid separation, etc. There are common forms such as bag filters and cartridge filters. Information filtering, filtering out these impurities and particles, and in the gas-liquid separation section, Chinese wire mesh and other forms are mostly used.

1. Hydrogenation section

The working solution undergoes hydrogenation reaction under the action of palladium catalyst, and the generated hydrogenation solution is deoxidized after the filter. All incoming gases in this process need a filter to ensure the purity of the student’s reaction. The palladium catalyst company in the reaction itself is of great value for the development and recovery of the enterprise. It is necessary to use the filter information for classification and recovery. The filter has a huge impact on the hydrogenation reaction. In the downstream products of the hydrogenation tower, we generally set hydrogenation liquid separators and filters to remove the mixed gas or clay.

In the fluidized bed process, we also need to add a multistage filter catalyst, which will be very small and return to the oxidation tower intercept, while protecting the safety of the subsequent production process.

2. Oxidation section

In the oxidation section, the air needs to pass through the filter to remove the tiny particles in the ambient air, and then analyze and react with the hydrogenation liquid. After the oxidation technology reaction process is completed, the oxidized liquid enters an extraction time stage after passing through the filter.

The oxidized tail gas undergoes multi-stage demisting through condensation, cyclone, screen mesh, and activated carbon adsorption, and then enters the subsequent treatment.

3. Extraction section

In this section, all feed liquids need to be set with filters to prevent excess impurities from entering the extraction column and affecting product quality. A liquid phase separator and a liquid-liquid phase separator are set at the same time to remove excess water or solvent.

4. Post-processing section

The raffinate flows from the raffinate separator to the bottom of the drying column containing the traces of potassium carbonate solution and water mixed with the hydrogen peroxide removal herein. A filter lye is set up in this section, the lye prevents debris from entering the main process.

In the full acid production process, the alkali column is eliminated and a coalescer-based separator is used to separate the water as well.
