The diameter and insertion depth of the exhaust pipe have a great influence on the dust removal efficiency of the diy cyclone dust collector. The diameter of the exhaust pipe must be selected to a suitable value. The diameter of the exhaust pipe is reduced, which can reduce the rotation range of the internal swirl. The dust is not easily discharged from the exhaust pipe, which is beneficial to improve the dust removal efficiency, but at the same time, the speed of the air outlet increases and the resistance loss Increase; if the diameter of the exhaust pipe is increased, although the resistance loss can be significantly reduced, but the exhaust pipe is too close to the wall of the cylindrical tube, it is easy to form a "short circuit" phenomenon of internal and external swirling flow, which causes the external swirling flow Part of the unremoved dust is directly mixed into the exhaust pipe and discharged, thereby reducing the dust removal efficiency. It is generally believed that the diameter of the exhaust pipe is 0.5 to 0.6 times the diameter of the cylinder. If the exhaust pipe is inserted too shallow, it is easy to cause the dust-containing airflow of the air inlet to directly enter the exhaust pipe, which affects the dust removal efficiency; the exhaust pipe is inserted deep, it is easy to increase the friction surface of the airflow and the pipe wall, so that the resistance loss increases, and at the same time, The distance between the exhaust pipe and the bottom of the cone cylinder is shortened, which increases the chance of dust back to the mixed discharge. The insertion depth of the exhaust pipe is generally slightly lower than the bottom of the air inlet. Because the unit steel consumption of the diy cyclone dust collector is relatively large, the better method in the design scheme is to gradually decrease the thickness of the material from the top to the bottom of the barrel!
The main advantages of diy cyclone dust collector are as follows.
(1) It is convenient for multiple units to be used in parallel when dealing with large air volume, and the efficiency resistance is not affected.
(2) It can withstand high temperature of 400℃, if special high temperature resistant materials are used, it can also withstand higher temperatures.
(3) After the dust collector is equipped with a wear-resistant lining, it can be used to purify the flue gas containing high abrasive dust.
(4) The ash can be cleaned dry, which is beneficial to the recovery of valuable dust.
