UV photocatalytic purification activated carbon device

A wide-amplitude photon tube with 220v voltage and high intensity emits dual-band light (185nm,254nm) with balanced energy in a specific band to irradiate exhaust gas. UV high-energy ultraviolet beams are used to decompose oxygen molecules in the air to generate free oxygen. Due to the imbalance of positive and negative electrons carried by free oxygen, it needs to combine with oxygen molecules to generate ozone. Its reaction formula is:

Product Description

Laser level is a kind of instrument made by using red or blue visible rays and matching horizontal positioning instrument. It is used for measuring the flatness of the floor and belongs to surveying and mapping tools.

Can make objects in the same horizontal plane. Leveling is a ground construction. In building construction refers to the bricklayer wall, woodworking planing wood, etc. to make the surface of the high and low uneven flattening.

Generally used in building construction, with a level, ground instrument, etc., so that the surface of masonry or construction objects, sides, etc. look flat, no slope.

Laser level is an intelligent display device instrument, the role of laser level can be installed on the moving object, the acquisition of horizon signal, in a larger field of view to display the horizon, real-time display of the object's motion posture.

Laser level is of great significance to prevent spatial disorientation if it is applied to aircraft.

1. working principle

UV photocatalytic principle:A wide-amplitude photon tube with 220v voltage and high intensity emits dual-band light (185nm,254nm) with balanced energy in a specific band to irradiate exhaust gas. UV high-energy ultraviolet beams are used to decompose oxygen molecules in the air to generate free oxygen. Due to the imbalance of positive and negative electrons carried by free oxygen, it needs to combine with oxygen molecules to generate ozone. Its reaction formula is:

UV O₂→ O O (free oxygen) O or O O₂→O₃(Ozone). The use of high-energy UV high-energy ultraviolet light beams and ozone on the malodorous gases for synergistic decomposition and oxidation reaction, so that the malodorous gases are degraded into low molecular compounds, water and carbon dioxide, and then discharged through the air duct.

working principle of activated carbon adsorption:Adsorption is a phenomenon that occurs at the interface of two different phases, and the adsorption process is the diffusion process at the interface, which occurs on the solid surface, which is caused by the residual attraction on the solid surface. Adsorption can be divided into physical adsorption and chemical adsorption. Physical adsorption, also known as van der Waals adsorption, is caused by physical adsorption caused by electrostatic force or van der Waals attraction between adsorbent and adsorbate molecules. When the molecular attraction between solid and gas is greater than the attraction between gas molecules, even if the pressure of the gas is lower than the saturated vapor pressure corresponding to the operating temperature, the gas molecules will condense on the solid surface, physical adsorption is an exothermic process. Chemical adsorption, also known as active adsorption, is due to the chemical reaction force between the surface of the adsorbent and the adsorbate molecules, which involves the destruction and recombination of chemical bonds in the molecules, therefore, the adsorption heat of the chemical adsorption process is larger than the physical adsorption process. In the adsorption process, there is no strict boundary between physical adsorption and chemical adsorption. The same substance may be physically adsorbed at lower temperatures, while it is often chemical adsorption at higher temperatures. Activated carbon fiber adsorption is mainly based on physical adsorption, but due to the presence of surfactants, there is also a certain degree of chemical adsorption.

Technical characteristics of 2. equipment

UV photocatalytic purification equipment features:

1. Applicable environment: UV photocatalysis is suitable for completely oxidizing and purifying toxic and harmful odors such as waste gas into non-toxic and harmless low molecular components at normal temperature, and is suitable for treating toxic and harmful gases with medium concentration (the concentration can be evenly passed through by pretreatment), large gas volume (equipment can be combined for treatment) and strong molecular structure stability.

2, complete purification: through UV photocatalysis can directly oxidize the organic waste gas in the air into non-toxic and harmless substances, without leaving any secondary pollution.

3. High efficiency and energy saving: UV photocatalysis uses the vacuum wave ultraviolet light generated by artificial ultraviolet lamp as the energy source to drive the oxidation-reduction reaction, and uses the moisture and oxygen in the exhaust gas surface as the oxidant to effectively degrade the toxic organic waste gas. The biggest feature of UV photocatalysis is efficient purification and energy saving. UV photocatalysis has the characteristics of strong oxidation and effective decomposition, and is finally reduced to carbon dioxide (CO2), water (H2O) and other non-toxic and harmless substances, hydroxyl radical (OH-) and superoxide radical (O2-, O-), and its oxidation is higher than that of common ozone, hydrogen peroxide, potassium permanganate, hypochlorous acid, etc. 4, equipment long life, small footprint: purification system for the integration of the whole structure, equipment box material according to the requirements of the owner, you can choose stainless steel 304 or 316 material, the main equipment life of more than 10 years. Equipment covers an area of small, compact structure, beautiful appearance. Kill

Characteristics of activated carbon device for exhaust gas adsorption:

1. The adsorption of aromatic compounds is better than that of non-aromatic compounds.

2. The adsorption of branched hydrocarbons is better than that of linear hydrocarbons.

3. The adsorption of substances containing inorganic groups in organic matter is lower than that of substances without inorganic groups.

4. The adsorption of compounds with large molecular weight and high boiling point is higher than that of compounds with small molecular weight and low boiling point.

5. The higher the concentration of adsorbate, the higher the adsorption capacity.

6. The larger the internal surface area of the adsorbent, the higher the adsorption capacity.
