Desulfurized activated carbon pores are developed for chemical raw materials, gas chemical synthesis gas, carbon dioxide gas for gas and beverages for pharmaceutical industry, purification of nitrogen, hydrogen chloride inert gas, purification of atomic facilities, and also for the removal of pollutants and mixed gases in the air. The classification is purified. Illustration: Desulfurized activated carbon Desulfurization activated carbon is made from high-quality coal and refined with advanced process equipment. Its appearance is dark black columnar particles or amorphous particles, with a large specific surface area, suitable void structure, high mechanical strength, can withstand high temperature, high pressure, not easy to break, easy to regenerate, long service life and so on. This product is made of high quality coal as raw material and refined by advanced process equipment. Its appearance is dark black columnar particles or amorphous particles, with a large specific surface area, suitable void structure, high mechanical strength, can withstand high temperature, high pressure, not easy to break, easy to regenerate, long service life and so on. It is widely used in flue gas desulfurization in thermal power plants, oil refining, petrochemical and chemical fiber industries, desulfurization of raw material gas in chemical fertilizer industry, gas desulfurization in gas, natural gas desulfurization and other chemical industries, and is the best additive for carbon dioxide production. Model technical indicators: Activated carbon for gas phase desulfurization: TY-2.0 TY-3.0 TY-4.0; Strength (%): >95 >93 >90; Sulfur capacity (mg/g); Specific surface area (m2/g); Ash (%): ≤15 ≤15 ≤15; Moisture (%): ≤3 ≤3 ≤3; Particle size (mm): 2.0 3.0 4.0; Packing density (g/l) - 520 470-510. Technical indicators: (implementation standard GB/T 7701.1-1997) The desulfurized activated carbon is made of a sulfur-containing material and has a black appearance, no taste, no toxicity, and a developed internal pore structure. A kind of microcrystalline carbon material with large specific surface area and strong adsorption capacity is a commonly used adsorbent. Desulfurized activated carbon is divided into powder shape, granular shape, irregular granular shape, cylindrical shape, spherical shape and fibrous shape. Desulfurization activated carbon refers to the use of activated carbon to support sulfonated titanium cyanide in the process of gasoline refining to remove excess thiol from crude oil, thereby reducing the sulfur content of gasoline and improving quality. In line with national environmental emission requirements. Desulfurization activated carbon features: 1. Large specific surface area and high adsorption value. As the activated carbon loaded with sulfonated titanium cyanide, the adsorption value of methylene blue is required to be high, the mesopores are developed, and the load exceeds that of ordinary activated carbon. 2, good strength, not easy to break. Since the loaded sulfonated titanium cyanide cobalt activated carbon is repeatedly subjected to a pressure test in a fixed bed and the solution is soaked, the strength is required to be high, and the particles are preferably in a natural shape. 3. The content of ash impurities is small. In order to ensure a smooth chemical reaction of the catalyst, it is necessary to minimize the content of various impurities such as ash and metal ions in the carbon. Improve the pore utilization of activated carbon. 4. Low moisture. Keep the minimum moisture of activated carbon as much as possible to avoid affecting its function. All have undergone strict quality control, with developed pores, low ash content, strong adsorption capacity, good desorption, large surface area, high mechanical strength, long service life and many other advantages, coupled with low prices, the launch of the Nanjing market is praised. It has been widely used in environmental protection, sewage treatment, wastewater treatment, drinking water purification, air purification, chemical, gas protection, flue gas desulfurization, food, food decolorization, catalyst carrier, medicine, solvent recovery and many other fields.
The Optical Turnstile ( Speed Gate , flap
Barrier Gate , Swing Barrier ) are designed to work in a normally closed mode and
retract inside the pedestal after a valid card has been presented to allow the
authorized user to pass. This type pedestrian Turnstile Gate is usually used in
bank lobby, office building, fitness club, school, subway station and so
on. It prevents unauthorized people to
enter the restricted areas.
Our optical Turnstile is a physical security device designed to restrict or control access to a building or secure area. Optical Turnstiles are usually a part of an Access Control system, which also consists of software, card readers, and controllers. Optical turnstiles operate much like regular mechanical turnstiles, except that they rely primarily on electronic (infrared) beams, and audible/visual interfaces to control entry. Rather than physically restraining a person, the optical turnstile uses sounds and lights to alert others to attempted entry by unauthorized individuals. For this reason, they are not likely to be used in subways and stadiums, as they are suited for settings where design and aesthetics are important, such as lobbies. They are perfect for high rise buildings with a single path through the lobby and staffed reception. The rate of people passing through the optical turnstile is high, with less delay than other methods. They are also suitable for the handicapped, as they are Barrier -free.
