[0052] Referring to Fig. 1 again, this is a plan view of a sub-channel, from which we can understand the basic structure of the small-scale vortex generator and how it is arranged. General requirements: Vs≥Lv; Vs=0.5Wv~8Wv; Lv=0.5Wv~0.8Wv; Hw=(2.5~25)Wv; Sa=0.25Wv~2Wv;
[0053] The width Hw of the sub-channel may also be 100mm to 750mm, which can be determined according to the size of the main flue. The design principle is: first determine Wv, then other geometric parameters can be determined, or the width Hw of the sub-channel can also be determined first.
[0054] see you again figure 2 , is a schematic diagram of a blade that produces a small-scale vortex. The shape of the blade edge teeth is not strictly limited in theory, and can be hemispherical, stepped, triangular, etc. The α angle of the Z-shape is required to be greater than 90°.
[0055] see you again Figure 4 , it is quite obvious that turbulent vortices are formed in the folds of the blade 3 and in the wake o...

The invention discloses a device and a method for mixed fluid particle coalescence, wherein an airflow pipeline is longitudinally divided into a plurality of sub-channels by at least one sub-channel clapboard so that the fluid is divided into a plurality of sub-fluids; a coalescence device is respectively arranged in each sub-channel and comprises a square frame in the sub-channel, a plurality ofZ-shaped blades are fixed on the square frame, and a plurality of Z-shaped blades are longitudinally arranged along the sub-channel; the Z-shaped blades comprise plates folded in a Z shape longitudinally, both sides of the Z-shaped plates are respectively provided with a plurality of teeth, the Z-shaped blades are transversely arranged in the sub-channels, teeth at one side of each Z-shaped plateface to the coming direction of an airflow in each sub-channel, and the teeth at the other side of each Z-shaped plate are opposite to the coming direction of the airflow in each sub-channel. A plurality of small turbulent flow regions are created behind the large-size turbulent flow of the sub-flow upstream to obey the motion of the small turbulent flow, thus relative smaller particles in flue gas are coalesced for being conveniently removed.
Description
technical field [0001] The invention relates to a technology for removing tiny particles in flue gas, in particular to a device and method for agglomerating mixed fluid particles. Background technique [0002] In many industrial processes, small particles that are harmful to humans are emitted into the atmosphere. Among these particles are usually very small submicron particles that are easily inhaled by the human body and enriched in toxic compounds. Their combination of toxicity and ease of inhalation has attracted the attention of governments of various countries, and successively enacted strict laws to control the emission of particles with a diameter of microns, especially those with a diameter of less than 2.5 microns (Pm 2.5 ) of particulate matter. [0003] Smaller particles in atmospheric emissions are the main cause of reduced visibility caused by air pollutants, and the opacity of the atmosphere depends primarily on the amount of fine particles in the emissions....
