Abstract
The invention relates to a novel cyclone separator capable of effectively inhibiting the phenomenon of ash ring jacking, which comprises an exhaust pipe, an inlet, a secondary air inlet, a column section and a conical section, wherein two symmetrical secondary air inlets are arranged above a top plate of the column section. According to the cyclone separator, the two secondary air inlets arranged above the top plate of the column section of the cyclone separator can introduce airflow with a certain flow speed and the flow direction of the airflow is the same as the axis of the cyclone separator, and when particles entering the cyclone separator form an ash jacking ring below the top plate, the introduced airflow can blow the particles forming the ash jacking ring to the separation space, so that the ash jacking ring phenomenon is reduced, the wall surface abrasion is reduced, and the service life of the cyclone separator is prolonged.

Technical Field
The invention relates to a novel cyclone separator capable of effectively inhibiting the phenomenon of ash ring ejection, and belongs to the technical field of gas-solid separation.
Background
The cyclone separator is a device for separating particles from gas by utilizing centrifugal force, and is widely applied to the fields of chemical industry, environment and energy, as the requirement on the separation performance of the cyclone separator is higher and higher, a plurality of researchers optimize the structure and parameters of the cyclone separator, and hopefully, the phenomena of unfavorable particle separation such as ash jacking ring, backflow, particle back mixing and the like in the working process of the cyclone separator can be weakened or even eliminated.
Disclosure of Invention
The invention aims to provide a cyclone separator which can effectively inhibit the phenomenon of ash ring, effectively reduce the abrasion of the wall surface of the cyclone separator and improve the particle separation efficiency.
The above technical problem of the present invention is solved by the following means.
The invention relates to a novel cyclone separator capable of effectively inhibiting the phenomenon of ash ring ejection, which comprises: the air exhaust pipe comprises an exhaust pipe (1), an inlet (3), a secondary air inlet (2), a column section (4) and a conical section (5).
The novel cyclone separator capable of effectively inhibiting the phenomenon of ash ring jacking is characterized by comprising two symmetrical secondary air inlets.
The novel cyclone separator capable of effectively inhibiting the phenomenon of ash ring ejection is characterized in that a secondary air inlet is arranged above a top plate and is in a fan shape.
According to the cyclone separator, the two secondary air inlets arranged above the top plate of the column section of the cyclone separator can introduce airflow with a certain flow speed and the flow direction of the airflow is the same as the axis of the cyclone separator, and when particles entering the cyclone separator form an ash jacking ring below the top plate, the introduced airflow can blow the particles forming the ash jacking ring to the separation space, so that the ash jacking ring phenomenon is reduced, the wall surface abrasion is reduced, and the service life of the cyclone separator is prolonged.

Fig. 3 is a top view of the present invention.
In the figure: (1) an exhaust pipe; (2) a secondary air inlet; (3) an inlet; (4) a column section; (5) a conical section.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1 to 3, a novel cyclone separator for effectively suppressing the soot-trapping phenomenon includes: the air exhaust pipe comprises an exhaust pipe (1), an inlet (3), a secondary air inlet (2), a column section (4) and a conical section (5).
The novel cyclone separator capable of effectively inhibiting the phenomenon of ash ring jacking is characterized by comprising two symmetrical secondary air inlets.
The novel cyclone separator capable of effectively inhibiting the phenomenon of ash ring ejection is characterized in that a secondary air inlet is arranged above a top plate and is in a fan shape.
The working principle of the invention is as follows: when the cyclone separator works to form an ash pushing ring, the particles forming the ash pushing ring are blown to the separation space by airflow introduced from the secondary air inlet, so that the ash pushing ring phenomenon is reduced, and the particle separation efficiency is improved.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
