The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of Analytic Tower that is applied to sulfur dioxide smelting smoke absorption resolving, comprise the housing 1 processing with titanium steel composite board, mist eliminator 3, housing 1 is by upper shell 101, middle shell 102, lower house 103 forms, described upper shell 101 is provided with gas vent 16, lower house 103 is provided with condensate liquid inlet 10, liquid outlet 14, liquid entrance 13 again boils, described mist eliminator 3 is located in upper shell 101, the below of described mist eliminator 3 is provided with acid separating device 6, the below of described acid separating device 6 is provided with packing layer 7, packing layer 7 is that acid resistant porcelain ring is by grate plate 8 and crossbeam 9 carryings, described acid separating device 6 is formed by connecting by least two group acid traps, described acid trap comprises main acid tube 17, acid distributing tube 18, divide acid tank 19, downspout 21, described acid distributing tube 18 is communicated with a minute acid tank 19 by T-shaped threeway cloth acid tube 22, within described adjacent two minutes, acid tank 19 connected by communicating pipe 20.
T-shaped threeway cloth acid tube 22 comprises horizontal cloth acid tube 221 and vertical cloth acid tube 222, and the diameter of described horizontal cloth acid tube 221 is greater than the diameter of vertical cloth acid tube 222, and horizontal cloth acid tube 221 is provided with a plurality of cloth acid hole 23.
Described mist eliminator 3 is two and is fixed in upper shell 101 by brace summer 4, and brace summer 4 is connected with acid separating device 6 by suspension rod 5; Described upper shell 101 is provided with the first manhole 2, and described the first manhole 2 is two; Described lower house 103 is provided with liquid level gauge mouth 11, the second manhole 12, sewage draining exit 15; The liquid entrance 13 that boils is again connected with reboiler outlet, and lean solution, after reboiler heating, under higher temperature, pressure, enters Analytic Tower with liquid form, produces flash distillation in Analytic Tower, carries out secondary parsing, produces steam, and desorbed solution is carried out to secondary parsing.
Desorbed solution enters Analytic Tower by main acid tube 17, is distributed to each open type divides in acid tank 19 through main acid tube 17 inflow acid distributing tubes 18, and acid distributing tube 18 enters a minute acid tank through T-shaped threeway cloth acid tube 22.In order to make minute acid tank 19 inner boundaries stable, horizontal cloth acid tube 221 can not be too short, in order to avoid two goes out acid, causes greater impact apart from being too near to; Secondly, horizontal cloth acid tube 221 diameters are greater than the diameter of vertical cloth acid tube 222, reduce flow velocity, and in horizontal cloth acid tube 221 both sides, offer some cloth acid hole 23 and let out acid, and 221 liang of horizontal cloth acid tubes of reduction bring out sour impulsive force.Like this, can guarantee that the interior liquid level of minute acid tank 19 is without great fluctuation process.Communicating pipe 20 is connected as a single entity each minute acid tank 19, and each minute acid tank 19 played secondary adjustment and guarantee that minute acid tank 19 liquid level is identical.For acid in an all minutes point minute acid amount in tower is equated, within each minute, acid tank 19 must be in same level, carry out a fraction acid, by minute acid tank 19, flow into downspout 21 and complete two fraction acid, downspout 21 use overflow modes are distributed to each minute sour point, the lemon sodium mixed liquor that downspout flows out flows out by the liquid level static pressure in minute acid tank, and sour levelling is steady, guarantees that downspout 21 evenly goes out acid.The advantages such as have the sectional area of freely ventilating large, it is few that sour foam is carried secretly, and operating flexibility is large, is difficult for stopping up, and minute sour dot density is large, is convenient to install, debugging and maintenance, and acid mist is low, and tower resistance is little, reach the work of uniform acid distribution mode.
