The spray device
(57) Abstract:The device is intended for dispersing the liquid and can be used in scrubbing machines, scrubbers, heat exchangers, etc. In the invention enhances the quality of atomization (achieving uniform density, irrigation, homogeneous fine-grained structure of the formed drops) when increasing the performance of a single device. The device includes a housing with a Central cavity in the transverse axis of which is made of several equidistant from each other cylindrical channels. The latter are located on the longitudinal axis of the housing and mated with the V output gap. Thus the ratio of the distance between the centers of the channels to their diameter lies in the range of 2 to 3, the width of the output nozzles formed by the intersection of cylindrical channels with V-slit is 0.2 to 0.5 of the diameter of the channels, and the ratio of the height of the V-slit to the width of the output nozzles lies in the range 6 - 12. 3 Il. The invention relates to devices dispersion liquid and can be used in scrubbing machines, scrubbers, heat exchangers, etc.Known flat-flame nozzle [Reference piperato. Site atomization nozzle consists of a thin plate, in which the stamping get profiled groove with nozzle oval or rectangular shape.The disadvantage of this device is the uneven distribution raspisivaem liquid over the cross section of the torch, which is determined by the shape of the output section of the nozzle. Up to 50% raspisivaem fluid is in the peripheral zone, where the droplet size is significantly greater than in the center of the torch.Closest to the proposed technical solution is the nozzle for receiving the flat jet, comprising a housing with a Central cavity in the form of a hemisphere and a slit having V input area [and.with. N 923633, CL In 05 In 1/04, 1982].In this case, since the outlet of the nozzle has the shape of an ellipse, the fluid flow axis of the nozzle is larger than at the periphery. In addition, with the increase in the absolute size of the nozzle (to improve performance) increase the size of the formed droplets occurs jet mode, leakage of the fluid that degrades the quality of the spray as a whole.The invention provides the technical result is to improve the quality of dispersion (dispersion, uniformity and cover the query result is provided in the spray device, comprising a housing with a Central cavity and wedge output gap due to the fact that according to the invention, the Central cavity is connected to the V-output slit means located on the longitudinal axis of the housing cylindrical channels, equidistant from each other on the transverse axis of the housing, and the ratio of the distance between the centers of the channels to their diameter lies in the range of 2 to 3, the width of the output nozzles of the device formed by the intersection of cylindrical channels with V-slit is 0.2 to 0.5 of the diameter of the channels, and the ratio of the height of the V-slit to the width of the output nozzles lies in the range of 6-12.In Fig. 1 shows a spraying device - General view; Fig. 2 - cross section a-a of the device of Fig. 3 is a bottom view (from the side).The spray device includes a housing 1 with a Central cavity 2, which is cylindrical channels 3 located on the longitudinal axis of the housing, is connected to the V-output gap 4. The diameter of cylindrical channels dtothe distance between their centers atothe height of the V-slit hy. At the intersection of cylindrical channels with V-slit formed output spray nozzle 5 of a width of Iy. The slit is made through throughout the/P> Raspylyaemye liquid is fed into the Central cavity of the body, where it is distributed along the cylindrical channels and fed to the output distribution nozzles. Because of their cross-section is a gap (the ratio of the width of the Iyto the length of dtois 0.2 to 0.5), the flowing stream at the entrance to the nozzle is compressed, and the output from it extends in a plane parallel to the slit, getting a flat fan-shaped. This side faces of the V-slits serve as guide vanes forming the spray and determining its geometrical parameters. The length of the guide section (hyin 6-12 times the width of the output nozzle (Iy), which ensures the formation of a stable, flat jet with opening angle corresponding to the angle of the V-slit.The distance between the centers of cylindrical channels ato(and, correspondingly, between the centers of the output nozzles) is chosen from the condition of uniform density irrigation in the cross section of the spray. If (ato/dto< 2 peripheral portions adjacent torches overlap directly at the exit of the nozzles before the formation of droplets, which subsequently increases their size and density of the PR is, the e time to connect in the guiding device (V-slit), so the density of irrigation between the axes of adjacent nozzles becomes smaller than average, which also degrades the quality of the work of the nozzle.Use one device for multiple nozzles located on its longitudinal axis, can proportionally increase the performance of the spray device while maintaining a high dispersion of the spray. The latter value is inversely proportional to the geometric dimensions of the output channels (the smaller the size, the higher the dispersion of the formed droplets).These characteristics of the spray (high performance, dispersion, uniformity of the density of irrigation) is required when carrying out the processes of interphase mass transfer (particulate absorption, drying and others). Particularly suitable use of the proposed spray device in processing units of rectangular shape, i.e. when the cross-section of the mass transfer zone (reaction) and spray like that.For example, in Venturi scrubbers with external pipe-coagulation rectangular, used for ash removal in power plants, the use of Ukiyo spray. The spray device, comprising a housing with a Central cavity and wedge output gap, characterized in that the Central cavity is connected to the V-output slit means located on the longitudinal axis of the housing cylindrical channels, equidistant from each other on the transverse axis of the housing, and the ratio of the distance between their centers to the diameter of the channel is in the range of 2 to 3, the width of the output nozzles formed by the intersection of cylindrical channels with V-slit, is 0.2-0.5 diameters of the channels, and the ratio of the height of the V-slit to the width of the output nozzles lies in the range of 6-12.
