Description
Technical field
The invention belongs to dedusting and desulphurization washer, be specifically related to a kind of honeycomb-shaped Venturi dedusting and desulphurization washer that has.
Background technology
Dedusting and desulphurization washer is widely used in flue-gas dust-removing and desulfurization, and the structure of the Venturi tube that existing dedusting and desulphurization washer adopts all is the tubular structure that comprises contraction section, trunnion and expanding reach.Dust is realized collision, is contacted at the gas channel of tubulose with atomized drop with sulfur dioxide gas, thereby realizes absorption, the removal of dust separation and sulfur dioxide gas.The dedusting and desulphurization washer of this structure often because atomize insufficient, droplet skewness, influences the effect of dust-removal and desulfurizing.
Summary of the invention
The object of the present invention is to provide a kind of honeycomb-shaped Venturi dedusting and desulphurization washer, with the abundant mixing that realizes dust granules and sulfur dioxide gas and atomized drop, contact, address the above problem.
Technical scheme of the present invention is: honeycomb-shaped Venturi dedusting and desulphurization washer, it comprises the spraying section, and the spraying section connects the venturi pipeline section, and the venturi pipeline section connects cyclone separator, baffle evenly is set in the venturi pipeline section, and baffle is made of with the cone that the diversion section two ends are connected diversion section.
Connect by connecting filament between the diversion section of described baffle.
The cone angle of the cone angle of the cone of diversion section one end and the cone of the diversion section other end varies in size.
Baffle is arranged in the Venturi tube; The adjacent baffle of same row or same row is connected by connecting filament, and the space between the baffle is gas-solid liquid three-phase high turbulence space.
The spraying section is provided with the taper expanding reach for shrinking taper between Venturi tube and the cyclone separator.
This dedusting and desulphurization washer adopts the baffle of special construction, utilize the slit of the formation of many cones to constitute the gas channel of venturi, dust and drop can crossfires in gas channel, collision space and probability between dust and the drop have been increased, promptly strengthened the turbulent flow of air-flow, increased the contact area and the absorption liquid Surface Renewal speed of sulfur dioxide and absorption liquid, made that sulfur dioxide gas and mixing of absorption liquid are more abundant, more effective, assimilation effect is better.This equipment volume is little, and is simple to operate, cost is low, operating cost is low.The desulfuration efficiency of this equipment is in 70%～90%; To fine dust efficient is 85%～95%; Washer resistance≤2000Pa.

Fig. 2 baffle is provided with structural representation.
The specific embodiment
Present embodiment is used for the explanation to claims of the present invention, and protection scope of the present invention is not limited to following structure.
As shown in Figure 1, spraying section 2 is for shrinking taper, and spraying water supply installation 1 is located at spraying section 2.Spraying water supply installation 1 comprises that feed pipe 1.1 and feed pipe 1.1 connect is located at nozzle 1.2 in the spraying section 2.Spraying section 2 connects Venturi tube 3, and Venturi tube 3 ends are established taper expanding reach 3.1, and the taper expanding reach is connected with cyclone separator 4.Cyclone separator 4 is identical with existing structure, and its structure is not this tired stating.
Baffle 5 evenly is set in the venturi pipeline section 3, and baffle 5 is made of the cone 5.2,5.3 that diversion section 5.1 is connected with the diversion section two ends.Baffle 5 is arranged in the venturi pipeline section with the arrangement of row and column; Baffle 5 is located at (as shown in Figure 2) in the venturi pipeline section with the rectangle or the foursquare form of horizontally-arranged and file in the present embodiment.Can certainly arrange with other forms according to the shape in venturi pipeline section cross section, as diamond array, or polygon is arranged or circular arrangement.The cone angle of cone 5.2 and cone 5.3 varies in size, the cone angle of the cone 5.2 of close spraying section is greater than the cone angle of the cone 5.3 of close cyclone separator in the present embodiment, form shrink space section 5.4 of shrinking fast and the space segment 5.5 (shown in Figure 1) that slowly enlarges like this.Baffle 5 adopts the heat-resistant, wear-resistant resistant material.
Connect by connecting filament between the diversion section of baffle.Can connect by single connecting filament between the adjacent diversion section, also can connect by the dual link silk.Connected by connecting filament between the diversion section of the adjacent baffle of same row or same row, perhaps row is connected by connecting filament with adjacent diversion section between being listed as.
Present embodiment as shown in Figure 2, baffle 5 is located in the venturi pipeline section with the foursquare form of horizontally-arranged and file, dual link silk 6 connections between the diversion section 5.1 of adjacent baffle among every row, the diversion section 5.1 and the spaces between the connecting filament 6 of adjacent like this two row are gas-solid liquid three-phase high turbulence space 7; Space among every row between adjacent two diversion sections constitutes turbulent flow space 8.Venturi pipeline section inwall connects support and connection silk 9, and support and connection silk 9 is connected with the diversion section 5.1 of baffle.Connecting filament 6 is connected the two ends of diversion section.Gas-solid liquid three-phase high turbulence space 7 communicates in the venturi pipeline section with turbulent flow space 8.
The cone 5.2 of above-mentioned baffle 5 and connecting filament 6 constitute similar cellular.The operation principle of this dedusting structure: dusty gas enters cone 5.2 spaces of Venturi tube by air inlet pipe by the spraying section, and air velocity enters the gas-solid liquid three-phase high turbulence space 7 between the diversion section 5.1 after sharply increasing; And the turbulent flow space 8 between the adjacent diversion section, in the relative motion of water droplet and dusty gas, grit surface parcel air film is broken back and wetting by water droplet, water droplet and dusty gas are used following air-flow, can be in high turbulence space 7 in a big way realization collision, the contact probability of grit and drop increases greatly, collision enforcement.Dusty gas with spray into and further atomized by high velocity air, turbulent flow space 8 and turbulent flow space 7 in, form the three-phase high turbulence, strengthen the ability of droplet capture dust, the raising dust removing effects.Equally, air-flow has increased the contact area and the absorption liquid Surface Renewal speed of sulfur dioxide and absorption liquid in turbulent flow space 8 and turbulent flow space 7, make that sulfur dioxide gas and mixing of absorption liquid are more abundant, more effective, and assimilation effect is better.
