Abstract
The invention relates to a cyclone separator for introducing secondary air from the upper side of an inlet, belonging to the technical field of cyclone separation. According to the cyclone separator, secondary air introduced from the upper side of the inlet of the cyclone separator blows airflow and particles entering from the inlet away from the upper side of the inlet for a certain distance when the airflow and the particles are about to enter a column separation space, so that the particles are prevented from forming an ash jacking ring below a top plate, the wall surface abrasion is reduced, and the service life of the cyclone separator is prolonged.
Description
Technical Field
The invention relates to a cyclone separator for introducing secondary air from the upper side of an inlet, belonging to the technical field of cyclone separation.
Background
The cyclone separator is a widely applied gas-solid separation device, has simple structure, convenient manufacture and maintenance, no moving parts and can continuously and stably operate under severe conditions of high temperature, high pressure and the like, but the internal flow field is more complex, particles easily form an ash ejecting ring in the flow field, and the abrasion of the wall surface is aggravated, so that the failure of the cyclone separator is caused.
Disclosure of Invention
The invention aims to provide a novel cyclone separator which can effectively prevent the formation of an ash jacking ring and reduce the abrasion of a wall surface.
The above technical problem of the present invention is solved by the following means.
The invention relates to a cyclone separator for introducing secondary air from the upper side of an inlet, which comprises: the device comprises an exhaust pipe (1), an inlet (3), a secondary air inlet (2), a column section (4), a conical section (6) and a dust exhaust port (7);
the separation chamber (5) is composed of the exhaust pipe (1), the inlet (3), the column section (4), the conical section (6) and the dust exhaust port (7), and the secondary air inlet (2) is formed in the upper side of the inlet (3).
The cyclone separator for introducing the secondary air from the upper side of the inlet is characterized in that the flow direction of the secondary air introduced from the secondary air inlet (2) is parallel to the axis of the cyclone separator.
The cyclone separator for introducing the secondary air from the upper side of the inlet is characterized in that the secondary air inlet is arranged at the tail end of the inlet and is tangential to the column section of the cyclone separator.
According to the cyclone separator, secondary air introduced from the upper side of the inlet of the cyclone separator blows airflow and particles entering from the inlet away from the upper side of the inlet for a certain distance when the airflow and the particles are about to enter a column separation space, so that the particles are prevented from forming an ash jacking ring below a top plate, the wall surface abrasion is reduced, and the service life of the cyclone separator is prolonged.

In the figure: (1) an exhaust pipe; (2) a secondary air inlet; (3) an inlet; (4) a column section; (5) a separation chamber; (6) a conical section; (7) a dust exhaust port.
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 cyclone separator for introducing overfire air into an upper side of an inlet, comprising: the device comprises an exhaust pipe (1), an inlet (3), a secondary air inlet (2), a column section (4), a conical section (6) and a dust exhaust port (7);
the separation chamber (5) is composed of the exhaust pipe (1), the inlet (3), the column section (4), the conical section (6) and the dust exhaust port (7), and the secondary air inlet (2) is formed in the upper side of the inlet (3).
The cyclone separator for introducing the secondary air from the upper side of the inlet is characterized in that the flow direction of the secondary air introduced from the secondary air inlet (2) is parallel to the axis of the cyclone separator.
The cyclone separator for introducing the secondary air from the upper side of the inlet is characterized in that the secondary air inlet is arranged at the tail end of the inlet and is tangential to the column section of the cyclone separator.
The working principle of the invention is as follows: when the particle-laden gas stream enters the cyclone from the inlet, secondary air introduced from the upper side of the inlet blows the gas stream and particles away from the upper side of the inlet for a distance to prevent the formation of soot rings.
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.
Claims (3)
1. A cyclone separator with overfire air introduced at the upper side of the inlet, comprising: the device comprises an exhaust pipe (1), an inlet (3), a secondary air inlet (2), a column section (4), a conical section (6) and a dust exhaust port (7);
the separation chamber (5) is composed of the exhaust pipe (1), the inlet (3), the column section (4), the conical section (6) and the dust exhaust port (7), and the secondary air inlet (2) is formed in the upper side of the inlet (3).
2. A cyclone separator with overfire air introduced at the upper side of the inlet according to claim 1, characterized in that the direction of the overfire air flow introduced from the overfire air inlet (2) is parallel to the cyclone separator axis.
