Product introduction

Cyclone dust collector is a type of dust removal device. The dust removal mechanism is to make the dust-laden air flow rotate, and the dust particles are separated from the air flow by centrifugal force and collected on the wall of the device, and then the dust particles fall into the ash hopper by gravity. Each component of the cyclone dust collector has a certain size ratio. The change of each proportional relationship can affect the efficiency and pressure loss of the cyclone dust collector. Among them, the diameter of the dust collector, the size of the air inlet, and the diameter of the exhaust pipe are the main influencing factors. . When using it, it should be noted that when a certain limit is exceeded, favorable factors can also be transformed into unfavorable factors. In addition, some factors are beneficial to improving the dust removal efficiency, but they will increase the pressure loss, so the adjustment of various factors must be taken into account.

The cyclone dust collector is composed of an inlet pipe, an exhaust pipe, a cylinder, a cone and an ash hopper. The cyclone dust collector has a simple structure, is easy to manufacture, install, maintain and manage, and has low equipment investment and operating costs. It has been widely used to separate solid and liquid particles from air streams, or to separate solid particles from liquids. Under normal operating conditions, the centrifugal force acting on the particles is 5 to 2,500 times that of gravity, so the efficiency of the cyclone dust collector is significantly higher than that of the gravity settling chamber. Based on this principle, a cyclone dust removal device with a dust removal efficiency of more than 90% has been successfully developed. Among the mechanical dust collectors, the cyclone dust collector is the most efficient one. It is suitable for the removal of non-viscous and non-fibrous dust, mostly used to remove particles above 5 μm, and the parallel multi-tube cyclone dust collector device also has a dust removal efficiency of 80-85% for particles of 3 μm. The cyclone dust collector is constructed of special metal or ceramic materials that are resistant to high temperature, abrasion and corrosion, and can be operated under the conditions of temperature up to 1000°C and pressure up to 500×105Pa. Considering the technical and economic aspects, the pressure loss control range of the cyclone dust collector is generally 500-2000Pa.

Features

According to the previous method of integrating the axial velocity with respect to the flow area, calculate the change of the descending flow of the conventional cyclone dust collector after installing different types of drag reducing rods, and calculate the percentage of the total flow rate of the descending flow dust collector at different sections under various conditions Drawn to show the difference between the average value of the overflow in the upflow and downflow areas, that is, the difference between the downflow and the actual overflow in the downflow area. It can be seen that the short-circuit flow and drop flow of each model change along the height of the dust collector. Compared with the conventional cyclone dust collector, the installation of full-length drag reduction rods 1# and 4# increases the short-circuit flow rate, but the installation of non-full-length drag reduction rods H1 and H2 reduces the short-circuit flow rate. After the installation of 1# and 4#, the variation law of the descending flow along the process is basically the same as that of the conventional cyclone dust collector, showing a linear distribution, and the three lines descend in parallel. But after installing H1 and H2, the distribution is a broken line instead of a straight line, and its inflection point is exactly the position of the section where the drag reducing rod is inserted from bottom to top. It can also be seen from this that the non-full-length drag reducing rod increases the descending flow at the sections above the section, and the descending flow is larger than that of conventional dust collectors. However, after contacting the drag reducing rod, the descending flow decreases rapidly, reaching the cone The bottom of the body reaches or is lower than the value of the conventional dust collector.

The reduction of short-circuit flow can improve the dust removal efficiency, increase the descending flow of the section, and increase the residence time of dusty air in the dust collector, creating more opportunities for dust separation. Therefore, although the drag reduction effect of the non-full-length drag-reducing rod is not as good as that of the full-length drag-reducing rod, it is more conducive to improving the dust removal efficiency of the cyclone dust collector. There is as much as 24% of the short-circuit flow near the inlet section of the exhaust core pipe of the conventional cyclone dust collector, which will seriously affect the overall dust removal effect. How to reduce this part of the short-circuit flow will be a research direction for improving efficiency. Although the drag reduction effect of non-full-length drag-reducing rods is not as good as that of full-length drag-reducing rods, it will be more effective because it reduces the short-circuit flow of conventional cyclone dust collectors and increases the flow rate of cross-section decline, which improves the dust removal efficiency of cyclone dust collectors. practical significance.
