Description

The invention relates to devices for the implementation of heat and mass transfer processes and centrifugal separation of gas-liquid systems and can be used in various industries to condition and purify process gases and air.

The purpose of the invention is to intensify the operation of the device and reduce its energy consumption due to the organization of the toroidal vortex process B of the precipitation chamber,

Figure 1 shows the proposed cyclone apparatus; Figure 2 is the same as the embodiment,

The cyclone apparatus contains a cyclone chamber 1 with an input 2 to be processed, a lower axial outlet nozzle 3 coaxially placed under the nozzle 3 a precipitating chamber 4 having a peripheral outlet 5 of the treated medium in the upper part, formed between the annular oval 6 and the annular reflector 7, made in confuser. On the bottom 8 of the settling chamber 4 there is a conic divider 9 coaxially with the nozzle 3. The device 10 for axial movement can be fixed either on the lid (FIG. O or on the settling chamber. 4 (FIG. 2)). In the latter version, the cap 6 serves as the bottom cyclone. cameras 1,

The device works as follows.

The gas flow enters the cyclone chamber 1 through the nozzle 2, twists and contacts with a finely dispersed liquid, in this case both the gas cleaning from impurities upon contact with the liquid and its cooling occurs. Under the action of centrifugal forces, the fluid and the particles wetted by it move to the periphery of chamber 1 and, together with the gas flow, enter the precipitation chamber 4, the stack along the walls of the nozzle 3.

The twisted jet entering the chamber 4 reaches the splitter 9, after which the gas flow reverses the direction, moving upwards along the walls of the chamber 4, and drops of water with particles of separating material contained in them eject to the bottom 8 and chamber 4 walls. In the upper part of chamber 4, with the help of a reflector 7, the gas flow is directed to the axial zone, where part of the stream is ejected by a swirling axial jet and moves in the direction of the splitter 9, and the other part is rotated 180 ° and enters ny in the peripheries outlet 5 formed between the reflector 7 and the lid 6.

Due to the ejection of a part of the gas flow enveloping the reflector 7, a toroidal vortex is formed in the precipitation chamber 4. The power of the toroidal vortex is increased due to

increase the flow rate of the ejected flow (up to 75% of the total flow rate through the horizontal section of the toroidal vortex) by adjusting the distance between the reflector 7

and a cover 6 with the aid of the device 10. The powerful toroidal vortex is characterized by high circumferential flow rates simultaneously rotating around the axis of the chamber 4 and around the section

torus, About the power of the toroidal vortex is judged by drift of particles of various sizes placed on the edge of the reflector 7 into the iriose zone. When a powerful toroidal vortex occurs

The entrainment of particles into the axial zone of chamber 4 is observed even at a height of 5-10 mm above the edge of the reflector 7.

Part of the stream forming the toroidal vortex and containing particles of material that could not be separated in chamber 1 repeatedly falls into the region of intense coagulation (shaded). This region is characterized by high relative velocities of particles entrained in the gas flow and trapped by a toroidal vortex, and particles in a swirling jet, in particular, water droplets flowing

from chamber 1, coagulation of material particles in the indicated areas intensifies the separation process on the walls of the precipitation chamber 4.

The sedimentation chamber of the proposed design reduces the aerodynamic resistance of the device by approximately 25%.
