"153" nano-catalytic flue gas desulfurization and denitration device can save more than 50% year-on-year
On August 9th, the “153†nano-catalyzed flue gas desulfurization and denitration device developed by Beijing Putai Technology Development Co., Ltd. passed the expert appraisal in Beijing. “The R&D unit uses the oxidation method to develop the flue gas desulfurization and denitration technology, and its direction is correct. It has a good application prospect after the technology is perfected,†said Zhang Fan, the leader of the expert group and a researcher at the China Academy of Environmental Sciences.
Cui Chengzhe, general manager of the company, said that compared with the wet flue gas desulfurization technology commonly used in domestic power plants, the “153†device adopts the electronic catalysis and dust flocculation process, which can be realized without the expensive ammonia-containing redox agent. The goal of denitrification; nano-catalysis technology can make sulfur dioxide and nitrogen dioxide fully react or decompose in a few seconds, greatly shortening the reaction time; especially low-density catalytic wall and liquid membrane adsorption system, no need for booster fan and high-pressure circulating water pump, The energy saving is ≥50%.
“Simply speaking, taking a 10-ton coal-fired boiler as an example, the cost of flue gas, water and electricity for the treatment of 1 ton of coal by conventional technology is about 38 yuan. The technology only needs about 8.4 yuan; the cost of the boiler is about 80,000 yuan. The technology is about 50,000 yuan." Cui Chengzhe said.
After listening to the introduction, experts believe that the device uses catalytic oxidation technology to greatly increase the oxidation and absorption rate of sulfur dioxide and nitrogen oxides, reduce the volume of desulfurization and denitration tower, moderate equipment cost, and high cost performance.
This seminar was organized by the Beijing Invention Association. “Cui Chengzhe was awarded the Gold Medal of Beijing Invention and Innovation Competition twice in 2009 and 2012. The self-developed thermal storage electric heating, non-metallic heating body and other technologies have been widely promoted. I hope the device can also get the market. Recognition," said Zhong Zhijun, deputy secretary general of the association.

LED Therapy Light High Power, include 3 wattages, 300w 500w 1000w, 300w with 50pcs led, 500w with 1000cs led, 1000w with 200pcs led.
Why use led therapy light?
Red light therapy is a skin care treatment being offered as an alternative to physician-administered laser therapy.
Nost studies is involving red light therapy revolve around the treatment of acne, and of its ability ti get rid of wrinkle, while research is not yet conclusive on the benefits of red light therapy, studies suggest that concentrated red light is absorbed y the mitochondria in the cells and stimulates the generation of more collagen.
