Electrode gas purifier (preprocessor)

¥ Electricity Model: QT106-DJ Updated on: April 1, 2024 Product Catalog

Gas purifier (also known as preprocessor) is used to purify the measured gas. Devices for protecting sensors (electrodes, probes) in gas analyzers. In the monitored gas, the main factors affecting the electrode life are the pollution of coal tar, h2s and so2. The coal tar blocks the micro pores of the electrode head film, and h2s and so2 cause the electrode head to produce ag2s, thus reducing the effective conductive area of the electrode head. In serious cases, the instrument cannot be adjusted to 21% in the first calibration, which is called electrode poisoning.

Wuxi Active Carbon Adsorption Box Dry Chemical Adsorption Deodorization Haoyou Environmental Protection Direct Selling Manufacturer

¥ Electricity Model: HJHXT Updated on: May 23, 2024 Product Catalog

Activated carbon adsorption tower can also be called activated carbon adsorber, activated carbon adsorption filter and activated carbon adsorption tank. Activated carbon is a very small carbon particle with a large surface area, and there are also small pores capillary tubes in the carbon particle. This capillary tube has a strong adsorption capacity. Because the surface area of the carbon particle is large, it can fully contact with gas (impurities). When these gases (impurities) touch the capillary tube, they will be adsorbed and play a purification role. The essence of activated carbon adsorption is to use the characteristics of activated carbon adsorption to adsorb the organic solvent in the low concentration and high air volume exhaust gas to the activated carbon.

Liquid nitrogen refers to liquid nitrogen. Liquid nitrogen is inert, colorless, odorless, noncorrosive, nonflammable, and low temperature liquid. When vaporizing, a large amount of endothermic contact will cause frostbite. Nitrogen constitutes the majority of the atmosphere (78.03% by volume and 75.5% by weight). Under normal pressure, the boiling point of nitrogen is - 196.56 ℃, and 1 cubic meter of liquid nitrogen can expand to 696 cubic meters of pure gaseous nitrogen (21 ℃). If pressurized, liquid nitrogen can be obtained at a higher temperature.
