The tightness of the lower part of cyclone dust separator is another important factor that affects the efficiency of dust removal. After the dust-containing gas enters thecyclone dust separator, it makes a helical rotation movement from top to bottom along the outer wall. This downward rotating airflow reaches the bottom of the cone, turns upward, and rotates upward along the axis. The pressure distribution in the cyclone dust separator is that the pressure change in each axial section is small, and the radial pressure change is large (mainly referring to static pressure), which is determined by the distribution of the axial velocity and radial velocity of the airflow. The airflow makes a circular motion in the cylinder, the pressure on the outside is higher than the inside, and the static pressure is the highest near the outer wall, and the static pressure is the lowest at the axis. Even if the cyclone moves under positive pressure, the axis is still under negative pressure, and the negative pressure extending to the ash discharge port is the largest. If it is slightly less tight, a larger air leakage will occur, and the dust that has settled is bound to It is carried out of the exhaust pipe by the upward air current. Therefore, in order to make the dust removal efficiency meet the design requirements, it is necessary to ensure the tightness of the ash outlet, and in the case of ensuring the tightness of the ash outlet, the dust at the bottom of the cone of the dust collector should be removed in time, if it can not be continuously and timely discharged, High concentration dust will flow at the bottom, causing excessive wear of the cone.
The advantages of the cyclone dust separator are
(1) Because the whole process of convection heat transfer and heat conduction occurs together during the whole process of vapor and liquid touching, this kind of dust removal equipment not only has the function of ash removal, but also has the functions of reducing smoke and dust, digesting and absorbing harmful substances.
(2) Suitable for solving high temperature, flammable and explosive materials and harmful substances.
(3) The operation is normal, clean and efficient.
