Description
Technical field
The present invention relates to waste gas purification field, be specifically related to the high efficiency of transmission layer desulfurizer in desulfuration absorbing tower.
Background technology
Coal-burning boiler in use can continue to produce sulfur-containing smoke gas, therefore all needs sulfur-containing smoke gas to carry out desulfurization by flue gas desulphurization system; Flue gas desulphurization system comprises: the coal-burning boiler setting gradually, and sack cleaner, air-introduced machine, offers respectively outlet flue and the desulfuration absorbing tower and the chimney that enter mouth on upper and lower two side, and in desulfuration absorbing tower, upper strata is provided with spraying device of desulfurizing tower; Coal-burning boiler is connected with sack cleaner by the first smoke pipeline, sack cleaner is connected with air-introduced machine by the second smoke pipeline, air-introduced machine is by being connected with desulfuration absorbing tower with the smoke-intake pipe road that mouth communicates that enters of desulfuration absorbing tower downside, and desulfuration absorbing tower is connected with chimney by the 3rd smoke pipeline being connected with the outlet flue of its upside; When work, the sulfur-containing smoke gas that coal-burning boiler produces, under the effect of air-introduced machine, enters sack cleaner and desulfuration absorbing tower successively, finally discharges from chimney; Enter after desulfuration absorbing tower at sulfur-containing smoke gas, the spraying device of desulfurizing tower in desulfuration absorbing tower sprays desulfurizing agent downwards, and the sulfur-containing smoke gas moving upward carries out the outlet flue from desulfuration absorbing tower after desulphurization reaction and discharges with can contact to the desulfurizing agent falling.The gas flow rate that enters desulfurization reaction tower due to sulfur-containing smoke gas is fast, make time of contact of desulfurizing agent of sulfur-containing smoke gas and spraying device of desulfurizing tower ejection short, cause desulfuration efficiency low, be all to improve desulfuration efficiency by auxiliary desulphurizing device is set in desulfuration absorbing tower at present, the structure of auxiliary desulphurizing device is: the spraying device of desulfurizing tower in desulfuration absorbing tower and enter on the inwall between mouth to be provided with sieve plate.The operation principle of this auxiliary desulphurizing device is: after spraying device of desulfurizing tower is sprayed onto on sieve plate downwards, desulfurizing agent can form one deck desulfurizing agent moisture film on sieve plate, in the time that sulfur-containing smoke gas upwards passes through sieve plate, can produce bubbling effect to the desulfurizing agent moisture film on sieve plate, increase like this haptoreaction time of sulfur-containing smoke gas and desulfurizing agent, thereby improved desulfuration efficiency.The shortcoming of this auxiliary desulphurizing device is: on the one hand, sieve plate volume is large, Heavy Weight, and installation and maintenance are loaded down with trivial details, and cost is high, and enterprise's production and application cost is high; On the other hand, because desulfurizing agent has formed desulfurizing agent moisture film on sieve plate surface, and sieve plate in use easily causes the obstruction of sieve aperture in sieve plate due to fouling, so all can increase the resistance that sulfur-containing smoke gas moves in desulfuration absorbing tower, must strengthen the power consumption of air-introduced machine, guarantee flue gas is at the proper motion of flue gas desulphurization system, thereby causes the power consumption of air-introduced machine high, further increased enterprise's production and application cost.
Summary of the invention
The object of this invention is to provide that a kind of installation and maintenance are convenient, desulfuration efficiency is high and can reduce the high efficiency of transmission layer desulfurizer in the desulfuration absorbing tower of flue gas desulphurization system energy consumption.
For achieving the above object, the present invention has adopted following technical scheme: the high efficiency of transmission layer desulfurizer in described desulfuration absorbing tower, comprise: desulfuration absorbing tower, upper at desulfuration absorbing tower, on lower two side, offer respectively outlet flue and enter mouth, upper strata in desulfuration absorbing tower is provided with spraying device of desulfurizing tower, at spraying device of desulfurizing tower and enter to be at least provided with a high-efficiency desulfurization mechanism in the desulfuration absorbing tower between mouth, each high-efficiency desulfurization mechanism at least comprises two-layer parallel transport layer, the pipe that every layer of transport layer is bearing on desulfuration absorbing tower inwall by some parallel interval respectively forms, in each high-efficiency desulfurization mechanism, the pipe that pipe in every layer of transport layer is adjacent in transport layer is the distribution of antarafacial intersection.
Further, high efficiency of transmission layer desulfurizer in aforesaid desulfuration absorbing tower, wherein: at spraying device of desulfurizing tower and enter to be provided with a high-efficiency desulfurization mechanism in the desulfuration absorbing tower between mouth, high-efficiency desulfurization mechanism is made up of two-layer parallel upper transport layer and lower transport layer, the pipe that upper transport layer and lower transport layer are bearing on desulfuration absorbing tower inwall by some parallel interval respectively forms, and the pipe in upper transport layer is the crossing 90 ° of distributions of antarafacial with the pipe in lower transport layer.
By the enforcement of technique scheme, the invention has the beneficial effects as follows: by least two-layer parallel transport layer, when desulfurizing agent falls to after lower transport layer from upper transport layer, desulfurizing agent can form desulfurizing agent water curtain between upper transport layer and lower transport layer, increase like this time of staying of desulfurizing agent in desulfuration absorbing tower, thereby the haptoreaction time that has increased sulfur-containing smoke gas and desulfurizing agent, desulfuration efficiency is high; Due to the pipe smooth surface of composition transport layer, make pipe surface less scaling simultaneously, also can not increase the resistance in desulfuration absorbing tower like this, and then can not increase the energy consumption of air-introduced machine in improving desulfuration efficiency, enterprise's production and application cost is low.
