Introduction to Catalytic Combustion Equipment

Combustibles burn under the action of a catalyst. Compared with direct combustion, catalytic combustion has a lower temperature and more complete combustion. The catalysts used in catalytic combustion are multi-component substances of noble metals and metal oxides with a large specific surface area. For example, household catalytic gas stoves loaded with Pd or rare earth compounds can reduce the CO content in the exhaust gas and improve thermal efficiency. An alumina catalyst loaded with 0.2% pt can burn most organic compounds at 500℃, and deodorize and purify them to a chemical shift σ=1 or less. Catalytic combustion is flameless combustion, so it is suitable for occasions with high safety requirements, such as fuel cells using H2 and O2 as raw materials, and hand warmers using gasoline or alcohol as raw materials (the catalyst is Pt-impregnated asbestos). For example, to eliminate NOx smoke from chemical plants, fuel can be added to the smoke, and NOx can be converted into N2 gas through catalytic combustion with supported platinum and palladium catalysts. A combustion method in which combustible substances in harmful gases are decomposed and oxidized at a lower temperature using an appropriate catalyst. The key factor in catalytic combustion is the selection of the catalyst. There are many catalysts to choose from: according to their activity, there are palladium, platinum, rare earth and transition metal oxide catalysts; according to their shape, there are amorphous granular, spherical granular, monolithic honeycomb, mesh, wire felt and porous plate catalysts. The catalyst support is generally alumina and ceramic, in addition to natural zeolite, nickel-chromium wire and stainless steel wire.

Dimensions and structure of commonly used activated carbon adsorption and desorption devices in spray booths

Let's look at the size and structure of commonly used activated carbon adsorption desorption devices in spray booths. For cylindrical adsorption devices, the diameter is 1 to 2 m. For vertical adsorption devices, the height and diameter are approximately equal, and the activated carbon layer height is 1.5 to 1.8 m. For horizontal adsorption devices, the activated carbon layer height is 0.3-0.8m, which can be single-layer or multi-layer, and the gas flow rate is 0.3-0.6m/s; if the layer height is increased, the adsorption capacity and power cost will increase accordingly.

Mobile spray booth: price and classification of spray booths

The price of spray booths varies. According to investigations, the price of normal to low-end spray booths in China ranges from 22,000 to 60,000 yuan, while high-end ones range from 60,000 to 150,000 yuan. There are many types of products, but they are basically used for surface spraying and painting of workpieces in the automotive, hardware, machinery, furniture, and chemical industries.

Mobile spray booth manufacturer brief introduction: The technical principle of environmentally friendly telescopic booth

Environmentally friendly retractable spray booths are currently among the most technologically advanced spray booths in the world. They have changed the scope of work of old spray booths, which suffered from serious pollution, poor paint mist handling capabilities, poor safety, unstable performance, and non-compliance with environmental protection requirements. Below, a mobile spray booth manufacturer will briefly describe the technical principles of environmentally friendly retractable spray booths.

Introduction to waste gas treatment methods for large-scale retractable mobile spray booths

In the painting process of large-scale telescopic mobile spray booths, waste gas is inevitably generated, which not only pollutes the environment but also harms human health. Therefore, it is crucial to treat this waste gas. The main methods for waste gas treatment in spray booths include: water spraying method, combustion method, absorption method, condensation method, plasma low-temperature catalytic oxidation method, and adsorption method. Among them, the most commonly used are the water spraying method and the adsorption method.
