及注意事项过滤风速是酸雾净化塔选型的关键参数之一。 How to use an acid mist purification tower
and precautions Filtering wind speed is one of the key parameters for selecting an acid mist purification tower. It should be comprehensively determined according to the characteristics, particle size, temperature and concentration of dust or smoke in different applications. The imported dust concentration is generally 15-30g / m3, the filtering wind speed is not more than 0.6-0.8m / min, the imported dust concentration is 5-15g / m3, the filtering wind speed is not more than 0.8-1.2m / min, when the dust concentration is less than 5g / m3 At this time, the filtering wind speed is not more than 1.5-2m / min. In short, in order to reduce the resistance of the equipment, it should not be too large when selecting the filtering wind speed.
The acid mist purification tower uses PS or PSU polymer coated fiber filter material. When the filtering gas is at room temperature or below 100 ° C, a PS polymer-coated fiber filtering material is generally used. If PSU polymer-coated fiber filter materials are used at high temperatures, PSU polymer-coated fiber filter materials should be used. If it is used in a place with special requirements, it should be stated before ordering and another filter material should be selected.
Use and precautions of acid mist purification tower:
1. When using the SST series acid mist purification tower, first check the integrity of the pipeline valves of each system, and whether the selection and proportion of the adsorption liquid are correct. When the adsorption liquid does not meet the requirements, it should be added in time. When starting, the pump should be turned on 3- 5 minutes before turning on the fan. NED is on. When shutting down the purification system, the fan should be turned off for 2-3 minutes before the pump can be turned off. Otherwise, the motor will be burned, the packing will be blocked, and the purification effect will be affected.
2. The connection of the fan and pump of the acid mist purification tower should absolutely ensure that it turns correctly and does not reverse. Otherwise it will damage the motor and cause an accident.
three. When the equipment is used and delivered, the user should send someone to keep it and use it. Regular inspections reveal abnormal noise or water leaks from the equipment. It should be closed and repaired before use.
Chapter Four. The equipment is installed outdoors. The motor of the pump fan should use a rain cover to prevent the motor from getting wet. No matter the equipment is installed indoors or outdoors, if a glass fiber reinforced plastic or plastic fan is used, a protective cover must be installed to prevent the screws from loosening, bearing damage or suction of debris, and impeller damage Explosions and injuries should be addressed. Cause an accident.
5. Replacement and configuration of purification solution of acid mist purification tower : The formula of our factory purification absorption solution is determined by the gas source and concentration of the user unit. After the equipment passes the test, it is provided to the user management personnel.
