Summary of the invention
The purpose of this utility model is to provide a kind of cellular venturi flue-gas dust-removing and desulfurization washer, to realize the abundant combination of dust and drop, addresses the above problem.
The technical solution of the utility model is: cellular venturi flue-gas dust-removing and desulfurization washer, it comprises the spraying section, the spraying section connects Venturi tube, Venturi tube connects cyclone separator, evenly at interval baffle is set in the Venturi tube, baffle is made of with the cone that the diversion section two ends are connected diversion section.
Dividing plate evenly is set in the pipe in the described mound, and dividing plate is connected with the diversion section of 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 with the arrangement of row and column; Connect dividing plate between the diversion section of the adjacent baffle of same row or same row, the space between the dividing plate of row and row or row and row 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 contact area and the absorption liquid Surface Renewal speed of sulfur dioxide in 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 greater than 70%～90%; To fine dust efficient greater than 85%～95%; Washer resistance≤2000Pa.
Description of drawings
The cellular venturi flue-gas dust-removing and desulfurization of Fig. 1 washer structural representation.
Fig. 2 baffle is provided with structural representation.
The specific embodiment
Present embodiment is used for the explanation to the utility model claims, and protection domain of the present utility model 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.
Evenly at interval baffle 5 is set in the Venturi tube 3, 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 tube with the arrangement of row and column; Baffle 5 is located at (as shown in Figure 2) in the Venturi tube 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 tube 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 abrasion-proof corrosion-proof corrosion material.
Dividing plate evenly is set in the Qiu Liguan, and dividing plate is connected with the diversion section of baffle.Single layer separator can be connected between the adjacent diversion section, also double-layer clapboard can be connected.Connect dividing plate between the diversion section of the adjacent baffle of same row or same row, perhaps row is connected dividing plate with adjacent diversion section between being listed as.
Present embodiment as shown in Figure 2, baffle 5 is located in the Venturi tube with the foursquare form of horizontally-arranged and file, connect double-layer clapboard 6 among every row between the diversion section 5.1 of adjacent baffle, the diversion section 5.1 and the space between the dividing plate 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 and two dividing plates constitutes turbulent flow space 8.The Venturi tube inwall connects supporting clapboard 9, and supporting clapboard 9 is connected with the diversion section 5.1 of baffle.
The cone 5.2 of above-mentioned baffle 5 and dividing plate 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 diversion section 5.1 and the dividing plate 6 after sharply increasing; And the turbulent flow space 8 between adjacent two diversion sections and two dividing plates among every row, 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.
