A fuse is also called a fuse, which is defined by the IEC127 standard as a "fuse-link". It is an electrical component that is installed in the circuit to ensure the safe operation of the circuit. A fuse is actually a short-circuit protector widely used in power distribution systems and control systems, mainly for short-circuit protection or severe overload protection. A fuse is a current protector made by applying this principle after the current exceeds a specified value for a period of time to melt the melt by its own heat. Fuses are widely used in high and low voltage power distribution systems and control systems as well as in electrical equipment. As short-circuit and over-current protectors, they are one of the most popular protection devices. A fuse is an overcurrent protector. The fuse is mainly composed of a melt and a fusion tube and an additional filler. In use, the fuse is connected in series to the protected circuit. When the current of the protected circuit exceeds a specified value, and after a certain period of time, the heat generated by the melt itself melts the melt, causing the circuit to be disconnected, thereby protecting effect. An electrical device that breaks a circuit with a metal conductor as a melt is connected in series in a circuit. When an overload or short-circuit current passes through the melt, the melt itself is heated and melted, thereby contributing to the power system, various electrical equipment, and household appliances. Certain protection. It has anti-delay characteristics. When the overload current is small, the fuse time is long; when the overload current is large, the fuse time is short. Therefore, within a certain overload current range until the current returns to normal, the fuse will not blow and can continue to be used. The fuse is mainly composed of a melt, a casing and a support 3, wherein the melt is a key component for controlling the fuse characteristics.

1. Product introduction
Coal-based columnar net gas Activated Carbon is cylindrical, tasteless non-toxic; as high quality Anthracite the raw material, by process of crushing, mixing, extrusion, molding, drying, carbonization, activation and made. It has reasonable pore structure, good adsorption properties, high mechanical strength, able to withstand the high temperature, high pressure and not easily broken, easy to regenerate, and low cost characteristics. It is widely used in sewage treatment, gas treatment, solvent recovery, desulfurization and denitrification, nitrogen making machine, air separation equipment, paint shop and other fields.
2. Application
a.Coal columnar net gas activated carbon used for purification, such as chemical raw materials, pharmaceutical chemical synthesis gas, industrial gas, nitrogen, chlorine, hydrogen chloride, ethylene hydrocarbons, ozone, ethane, butane, cracking gas, carbon dioxide and hydrogen used in beverage; atomic facilities exhaust inert gas and remove the pollutants; also separate and purify mixed gas. It also can be used for gas masks and protective equipment disinfection and filtration.
b.Coal columnar net gas activated carbon is mainly suitable for industrial waste treatment, such as waste gas power plant, chemical plant gas, coking plant, smelting plant, oil plant. Coal columnar net gas activated carbon rely on the good adsorption capacity, developed gap, high iodine value can make a cleaning purpose.
3. Adsorption purification principle and process
The physical properties of coal-based activated carbon introduction: it is cylindrical black particles; the physical, chemical properties analysis of carbon is a porous carbon, the highly developed pore structure makes it has large surface area, so it is easy to full contact with toxic and harmful gases in the air (and harmful impurities), so this highly developed capillary and pore structure formed a powerful adsorption force field, which gives the unique adsorption properties of activated carbon.
Adsorption: the organic waste gas passes through the filter removed the solid particulate material, from the upper to the lower into the adsorption tank. The organic matter is captured, absorbed and concentrated by the activated carbon, and the purified air is discharged from the lower part of the tank through the main fan into the atmosphere.
Stop: when activated carbon adsorption reached saturation,it stops to inhalation waste gas; and then blowing up into the steam through the activated carbon bed, which expelled the organic matter from the activated carbon, and the subsequent restoration of desorption, activated carbon activity is recycled.
Hot air drying and cooling: the activated carbon layer after desorption remains 80%-90% steam condensate which can in reducing carbon layer activity; therefore using the hot air to dry, close the steam valve, and then through the air cooling at 25 DEG C, activated carbon can be recovered into the circulation.
