RO membrane pore diameter is one millionth of the hair, the naked eye can not see, bacteria, viruses, it is 5000 times, RO membrane water purifier Therefore, Only water molecules can pass, other impurities and heavy metals are discharged by the waste pipe, so the process of desalination, as well as astronauts wastewater treatment are […]

China’s blast furnace gas dry bag dedusting technology after 30 years of application and development, has become increasingly mature, and in many small and medium-sized blast furnace to promote the use of. At the same time, in recent years, China’s filter material has also made great progress, fiber and ultra-fine glass fiber composite high-temperature needle […]

Bag filter is a dry filter device. It is suitable for the collection of small, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt, and the dust-containing gas is filtered by the filtering effect of the fiber fabric. When the dust-laden gas into the bag filter, the particles are […]

Denitrification catalyst is mainly used to reduce the emission of nitrogen oxides in the flue gas content, so as to achieve emission standards, reduce environmental pollution. In the above, “denitrification catalyst deactivated why recycling” refers to the use of denitration catalyst is large, and itself contains some heavy metals and other environmentally harmful substances, inactivated […]

As we all know, although the catalyst does not react with the reactants, but because of the particularity of its environment, its damage is relatively large, so its life is limited. Generally 3-5 years later will be inactivated, the need for new ones. Then the deactivation of the catalyst and how to deal with it? […]

SCR technology for denitrification in China more than 95% of the thermal power industry production line is widely used, but at the same time the technology in the glass furnace and other industrial furnaces also successfully applied, such as the cement industry. But there is a technical difficulty is low-temperature catalyst, in the “denitrification catalyst […]

SCR technology is the most mature denitrification technology in denitrification technology, its NOx removal rate can reach more than 80%. At present, SCR technology has become the mainstream technology of denitration in power plants at home and abroad. SCR denitrification technology using ammonia as a reducing agent, into the temperature of about 280 ~ 420 […]

Filter is now in many industrial production has played an important role in the effective removal of particulate matter or suspended solids, so that the need to filter the material to be filtered and purified, the filter is more clean. Filtration of the filter is a delicate thing, the filter before the use of the […]

Unless regular maintenance is carried out, the hydraulic oil, mechanical oil and refrigerated oil will remain contaminated, regardless of the installation and operation of the equipment. A reduction in the characteristics of the hydraulic oil is accompanied by an immediate failure of the equipment which is unavoidable. The cost of equipment failure than the hydraulic […]

It is essential ventilation and air conditioning system is the main force of the air filter. Made of bags is mainly to meet the large amount of wind, low resistance requirements. The proper use of the bag filter is to install a prefilter at the front of the bag filter, typically using a disposable paper […]
