A few things you must know about cleaning and installing silicon carbide nozzles
Silicon carbide high-efficiency nozzles are mainly used for desulfurization, denitrification, and dust removal in coal-fired power plants, which can prevent the flue gas emitted by power plants from directly polluting the atmosphere. The silicon carbide nozzle was chosen mainly because of its excellent properties such as high strength, high hardness, corrosion resistance, wear resistance, and high temperature resistance. According to the spray shape, silicon carbide nozzles can be divided into fan, cone, liquid column flow, air atomization and flat nozzles. At the same time, the names of the venturi nozzle, the forced air blowing nozzle and the special silicon carbide nozzle reflect the operating efficiency of the nozzle. Today I want to share with you the things you should pay attention to when cleaning silicon carbide nozzles and what you should pay attention to when installing.
First, the problems that should be paid attention to when cleaning silicon carbide nozzles
1. The cleaning damage of the silicon carbide nozzle should be within the limit, and corresponding measures should be taken to inhibit the corrosion that may be formed by the metal
2. The cleaning agent should be able to remove dirt quickly and thoroughly
3. Based on localization, the chemicals used to clean the silicon carbide nozzles are cheap and easy to obtain, and the cleaning cost is low without excessive capital consumption
4. Silicon carbide nozzle cleaner should not produce foam and odor, so as not to affect the cleaning process and on-site hygiene
5. The cleaning conditions of the silicon carbide nozzle cleaning agent are relatively mild, and do not depend on the strengthening conditions of the attachment port as much as possible. For example, there is no need to have too high requirements on temperature, pressure, mechanical energy, etc.
Second, the matters that should be paid attention to when installing the silicon carbide nozzle
1. For each welding system, ensure that the entire surface is involved in welding
2. The surface of the silicon carbide nozzle must be kept clean, otherwise the fastening effect will be reduced. The installer must check to ensure that all dust covered by the bonding area (such as packaging materials used during transportation) is blown clean
3. Keep the silicon carbide nozzle dry, and the bonding part is sufficient to withstand the pressure generated by the normal operation of the silicon carbide nozzle
4. The washer is off-axis, moderately tightened
