Embodiment Construction

[0029] In order to better illustrate the purpose, technical solutions and advantages of the present invention, the present invention will be further described below in conjunction with specific embodiments. This invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concept of the invention to those skilled in the art, and the present invention will only be defined by the appended claims.

[0030] Such as Figure 4-6 As shown, a precision agglomerator is installed in the area with high concentration of ultrafine dust in the inner cavity of the cyclone dust collector, and its axis coincides with the axis of the cyclone dust collector.

[0031] Such as Figure 4 As shown, the cyclone dust collector includes dust discharge pipe 1, star feeder 2, straight pipe section 3 of dust discharge pipe...

Abstract

The invention discloses a precision agglomerator, which comprises an agglomerating agent injection device, a diversion curved surface, a laminar flow shedding ring and a sea-fixing cone. The top of the diversion curved surface is connected with the laminar flow shedding ring, and the agglomerating agent nozzle is provided with the first injection port of the agglomerating agent, which is arranged under the diversion curved surface. The condition of collision and reunion; the laminar flow shedding ring is a circular ring with an outer diameter larger than the maximum outer diameter of the diversion surface, so that the bottom layer of the attached wall laminar flow of the dusty airflow rising along the diversion surface breaks away from the diversion surface and enters the high-speed flow of the spiral flow area, the upper part of the laminar shedding ring is connected to the Dinghai cone. In the present invention, the agglomerating agent is added to agglomerate ultrafine particles into large particles, and guide the flow to the region with higher tangential velocity to realize centrifugal separation, thereby improving the dust removal efficiency of the cyclone dust collector. The Dinghai Cone can avoid the phenomenon of dragon wagging its tail.

Description

technical field [0001] The invention belongs to the technical field of gas-solid separation, and in particular relates to a precision agglomerator. Background technique [0002] Since Morse invented the cyclone dust collector in 1886, many scholars have made outstanding contributions to its theoretical research and structural improvement. The application of cyclone dust collector is more and more extensive. So far, it has been the most important in-service equipment for gas-solid separation in environmental protection dust removal and powder production. However, the cyclone dust collector has been unable to effectively separate ultrafine particles with a particle size of <5 μm. The reason is that there is a back-mixing phenomenon in the ash hopper of the cyclone dust collector and a dragon tail phenomenon in the axial area between the separation cone section and the ash hopper of the spiral flow. These two reasons cause the separation efficiency of ultrafine dust to be...
