Rotary drum dryer is mainly used in building materials industry or metallurgical industry, such as slag, clay, coal powder, drying metal ore beneficiation leaching residue and other materials. Thus make the rotary dryer is subdivided into industrial rotary dryer, cement dryer, mining dryer, sand dryer, sludge dryer, etc. There will be a lot of dust for long-term use rotary drum dryer,if not promptly treated, will affect the normal operation of dust removal equipment. Henan Bailing will tell you about the several ways to clean the drum dryer.
1, the reverse flow cleaning. Literally, this approach is a relative movement state of the dust filter bag on the gas and exhibits, so the airflow dryer bag is deformed while generating vibration effect, so that it will leave the dust bag, thereby collected . This cleaning method generally bulging, relaxation and contraction Do not three states. When using this method of cleaning, pay attention to wait until the dust after a certain thickness, or else fall into a piece of dust can not affect the cleaning effect.
2, pulse cleaning. This approach iuse pulse to vibrate the drum dryer and dust bag. Pulse cleaning can be divided into two types: the injection pulse and pulsed gas tank. At present, China's domestic pulse cleaning are all commonly injection pulse.
3, acoustic cleaning. This approach use sound waves to make the rotary drum dryer bag vibration in order to achieve the cleaning purpose. This cleaning method has significant effects in the cement industry, zinc oxide, carbon black, etc. occur in the glass fiber filter bag, since the glass fibers in the repeated mechanical action are easily damaged, and sonic cleaning methods utilized the Sonicare, can well protect the glass fiber from damage.
4, mechanical cleaning. Mechanical cleaning subdivision, then, can be divided into high-frequency oscillation, artificial vibration and mechanical vibration of three. Among the four dryer bag cleaning work, this approach is the simplest one. In this way, there are three forms of exercise, are the horizontal direction of movement 'vertical motion and rapid vibration. These three ways drum dryer bag damage is relatively large, and clean thoroughly enough, this approach has gradually been replaced.
