The multitube acceleration smoke desulfurizer disclosed by the invention has the advantage of high desulfuration efficiency.
Description
Technical field
The present invention relates to the waste gas purification field, be specifically related to a kind of multitube and accelerate flue gas desulfur device.
Background technology
Coal-burning boiler in use can continue to produce sulfur-containing smoke gas, therefore all sulfur-containing smoke gas will be carried out to desulfurization by flue gas desulfur device, the structure of the flue gas desulfur device used at present is: comprise coal-burning boiler, desulfurization reaction tower, deduster, chimney, coal-burning boiler is connected with the desulfurization reaction tower downside by flue, desulfurization reaction tower is connected with deduster by flue, and deduster is connected with chimney by flue, and in desulfurization reaction tower, upper strata is provided with the desulfurizing agent spray equipment.The shortcoming of this flue gas desulfur device is: the gas flow rate that enters desulfurization reaction tower due to sulfur-containing smoke gas is fast, and the easy like this sulfur-containing smoke gas that causes is short with the time of contact of the desulfurizing agent sprayed from the desulfurizing agent spray equipment, and desulfuration efficiency is low.
Summary of the invention
The purpose of this invention is to provide a kind of multitube that a kind of desulfuration efficiency is high and accelerate flue gas desulfur device.
For achieving the above object, the present invention has adopted following technical scheme: described a kind of multitube accelerates flue gas desulfur device, comprising: coal-burning boiler is respectively arranged with outlet flue and the desulfurization reaction tower that advances mouth, deduster and chimney on upper and lower two side, coal-burning boiler is by being connected with desulfurization reaction tower with the flue that mouth is connected that advances of desulfurization reaction tower downside, desulfurization reaction tower is connected with deduster by the flue be connected with the outlet flue of its upside, deduster is connected with chimney by flue, at outlet flue and advance in the desulfurization reaction tower between mouth to be horizontally arranged with horizontal support, be evenly distributed with at least five group Venturi tube groups on horizontal support, every group of Venturi tube group at least comprises five Venturi tubes, be provided with shower in desulfurization reaction tower above Venturi tube, one end sealing of shower, the other end stretches out desulfurization reaction tower and prepares tower with desulfurizing agent and be connected, offer some spouts mouth spray down on shower.
Further, aforesaid a kind of multitube accelerates flue gas desulfur device, and wherein: described mouth spray flare opening arranges.
Enforcement by technique scheme, the invention has the beneficial effects as follows: the gas velocity of sulfur-containing smoke gas after Venturi tube can reduce, thereby increased the gas-liquid contact time of sulfur-containing smoke gas and desulfurizing agent, made fully haptoreaction of sulfur-containing smoke gas and desulfurizing agent, thereby improved desulfuration efficiency.
The accompanying drawing explanation
Fig. 1 is the operation principle schematic diagram that a kind of multitube of the present invention accelerates flue gas desulfur device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, described a kind of multitube accelerates flue gas desulfur device, comprising: coal-burning boiler 1 is respectively arranged with outlet flue and the desulfurization reaction tower 2 that advances mouth, deduster 3 and chimney 4 on upper and lower two side, coal-burning boiler 1 is connected with desulfurization reaction tower 1 by the first flue 5 be connected with 2 times side smoke inlets of desulfurization reaction tower, desulfurization reaction tower 2 is connected with deduster 3 by the second flue 6 be connected with its upside outlet flue, deduster 3 is connected with chimney 4 by the 3rd flue 7, at outlet flue and advance in the desulfurization reaction tower 2 between mouth to be horizontally arranged with horizontal support 8, be evenly distributed with at least five group Venturi tube groups on horizontal support 8, every group of Venturi tube group at least comprises five Venturi tubes 9, be provided with shower 10 in desulfurization reaction tower 2 above Venturi tube 9, one end sealing of shower 10, the other end stretches out desulfurization reaction tower 2 and prepares tower 11 with desulfurizing agent and be connected, offer some spouts mouth spray 12 down on shower 10, like this when sulfur-containing smoke gas after a plurality of Venturi tubes 9 on being uniformly distributed in horizontal support 8, the gas velocity of sulfur-containing smoke gas can reduce, and then increased the gas-liquid contact time of sulfur-containing smoke gas and desulfurizing agent, make fully haptoreaction of desulfurizing agent and sulfur-containing smoke gas, thereby improved desulfuration efficiency.In the present embodiment, described mouth spray 12 flare openings arrange, and can make like this desulfurizing agent can fully contact with sulfur-containing smoke gas, have improved desulfuration efficiency.In actual applications, the quantity of described Venturi tube group can arrange according to concentration and the gas velocity of sulfur-containing smoke gas.
Be only below concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the present invention's scope required for protection.
