Description

Technical Field

[0001] The utility model relates to the technical field of cyclone separator devices, in particular to a cyclone separator with increased dust removal efficiency. Background Art

[0002] Cyclone separator is a commonly used dust removal equipment, which separates solid particles from airflow by using the rotation and centrifugal force of airflow. This equipment is often used in industrial production to remove dust, particles and other impurities in the air to ensure the cleanliness and safety of the production environment.

[0003] Although cyclone separators are very effective in dust removal, they also have some limitations. For example, the dust removal effect of cyclone separators may be affected in cases where the particle size is small or the density is low. In addition, for some special gas components, cyclone separators may not be able to completely remove impurities.

[0004] In view of the above, the present application proposes a cyclone separator with increased dust removal efficiency, by increasing the radial distance from the inlet to the center of the cyclone separator to increase the centrifugal force, so that solid particles or droplets have more opportunities to be separated, thereby improving the effect of impurity treatment.

[0026] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is further described below in conjunction with specific embodiments.

[0028] The present application proposes a cyclone separator for increasing dust removal efficiency, which is specifically as follows;

[0029] For reference Figure 1-2 The present application is mainly composed of a cylinder 1, a spiral top 2 arranged on the top of the cylinder 1 and an ash discharge pipe 3 arranged at the bottom of the cylinder 1. When the gas enters the cylinder 1 through the spiral top 2, the solid particles or liquid droplets in the gas are separated by centrifugal force, and the droplets are discharged from the ash discharge pipe 3.

[0030] For reference Figure 1 The cylinder 1 includes a circular body 11, a conical body 12 and an elongated body 13; the end of the conical body 12 with a larger diameter is connected to the circular body 11, and the end of the conical body 12 with a smaller diameter is connected to the elongated body 13; in some special cases, the air flow or liquid flow cannot rotate for the required time inside, so that the separation effect is not ideal.

[0031] In order to further optimize the above-mentioned problems, the present application optimizes the circular body 11 and the conical body 12; firstly, in the existing, most of the built-in separator devices are also designed by connecting the circular and conical shapes, but the height of most of the circular shapes is higher than the conical end; in the present application, the conical body 12 is extended, so that in the present application, the height of the conical body 12 is higher than the circular body 11.

[0032] The flow in a cyclone separator consists of two main aspects: a) swirl or primary flow pattern axial flow or secondary flow pattern. The swirl primary flow pattern is used to apply a greater inertia or centrifugal force to the particles than the gas molecules. The purpose is to create a centrifugal field large enough so that the particles do not penetrate into the vortex core of the high-efficiency cyclone separator, where the gas will move upward and leave the separator. Another approach is to treat the centrifugal field as a barrier or boundary, just as we think of particle filtration, so that the particles cannot pass through the medium with a pore size smaller than the particle. The factors affecting the centrifugal force applied to the particles can be calculated by the centrifugal force equation (Fc = Vt2 / rM), where Fc is the centrifugal force, Vt is the tangential velocity, M is the mass of the particle, and r is the radius of the circular motion of the measuring point. It is obvious from this equation that the greater the tangential velocity, the greater the mass, and the smaller the radius of motion, the greater the centrifugal force. In view of this, we can ignore the mass of the particle because it will not change in any way. On the other hand, the tangential velocity and the radius of motion can be used as variables affecting the efficiency of the cyclone separator.

[0033] The tangential component of the inlet velocity of the cyclone separator air inlet 22 can be increased, and the radial distance between the inlet and the inner core of the high-efficiency cyclone separator can be increased to increase the tangential velocity. During the cyclone separator swirl process, due to the conservation of momentum, the tangential velocity will increase when moving to a shorter movement radius. Therefore, a spiral top 2 with the same diameter is set at the top of the circular body 11. The setting of the spiral top 2 can increase the length of the rotation path of the airflow inside the inner core, thereby extending the contact time between the airflow and the solid particles and enhancing the separation effect. The spiral top 2 includes a top shaft 21, an air inlet 22 and an air outlet 23; the top shaft 21 is spiral and has the same diameter as the circular body 11. The air inlet 22 is set on the side of the top shaft 21, and the air outlet 23 is set on the upper surface of the top shaft 21.

[0034] Furthermore, the setting of the circular body 11 and the spiral top 2 with equal diameters can reduce the resistance of the airflow inside and reduce energy loss, thereby improving the energy efficiency of the separator and reducing the operating cost.

[0035] In the area where the speed increases to maintain momentum, this flow phenomenon is called a free vortex. At a certain moment, the viscous force on the gas molecules prevents the increase of the tangential velocity, and the gas rotates in the form of a solid, fixed or forced vortex. Therefore, in addition to increasing the inlet speed to increase the centrifugal force, the centrifugal force can also be increased by reducing the diameter of the outlet pipe, reducing the diameter of the high-efficiency cyclone separator, or increasing the radial distance from the inlet to the center of the high-efficiency cyclone separator. Therefore, in this application, it is selected to set the height of the cone 12 higher than the circular body 11, and increase the radial distance from the inlet to the center of the high-efficiency cyclone separator to increase the centrifugal force. The increase in the height of the cone 12 part means that the airflow or liquid flow has more time and space to separate during the separation process. This may increase the contact time between solid particles or droplets and the airflow, thereby increasing the separation efficiency. At the same time, the rotation time of the airflow or liquid flow inside the separator may be extended, which helps to separate the solid particles or droplets more thoroughly, thereby achieving the effect of improving the separation accuracy.

[0036] For reference Figure 1 The ash discharge pipe 3 includes an upper shaft 31 and a lower shaft 32. The upper shaft is conical in shape, and the end with a larger diameter is connected to the bottom of the elongated body 13; the lower shaft 32 is cylindrical, and its diameter is connected to the end with a smaller diameter of the upper shaft 31; due to the setting shape of the ash discharge pipe, the resistance and pressure loss of the airflow can be further reduced, thereby achieving the effect of improving the efficiency of the system.

[0037] Furthermore, the dust discharge pipe 3 is mainly connected to the bottom of the elongated body 13, and the elongated body 13 can help to more effectively guide solid particles or liquid droplets into the dust discharge pipe 3, thereby optimizing the discharge of waste. By adjusting the position and design of the vertical pipeline, the waste can be more evenly distributed in the dust discharge pipe, reducing the residue or blockage of waste in the system.

[0038] In the utility model, the working steps of the device are as follows:

[0039] The gas is introduced through the air inlet 22 of the spiral top 2, and moves in the cylinder 1. Under the action of the special flow channel, the airflow makes a spiral motion from top to bottom in the cyclone separator. During the movement, the liquid droplets and dust particles with high density are thrown to the inner wall of the cylinder 1 under the action of centrifugal force, and fall into the cone 12 along the inner wall of the circular body 11 under the action of gravity. The airflow is in the inner layer, and the gas and solid are separated; among them, the cone 12 part of the cylinder 1 has a reduced rotation radius and an increased tangential speed, and the airflow and particles make a downward spiral motion. Near the bottom of the cone 12, the airflow turns into an upward rotational motion, and is finally discharged from the top outlet 23, and the large particles fall into the ash discharge pipe 3 for discharge.

[0040] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
