Background technology
In the industries such as electricity, iron and steel, wet electrical dust precipitator, as the end treating plant of flue gas purification system, carries out last degree of depth dedusting except mist process, to guarantee the minimum discharge of industrial smoke before fume emission. Flue gas keeps the stable of flow state to be the essential condition ensureing that electric precipitator outlet flue gas reaches lasting minimum discharge in wet electrical dust precipitator. If flue gas assignment of traffic between the electric field of wet electrical dust precipitator is uneven, local can be caused to run resistance increase, flow state is unstable, for the electric field that assignment of traffic is more, when having a power failure flushing, wet electrical dust precipitator very easily produces outlet dust and immediately discharges the phenomenon exceeded standard, thus can not reach continual and steady minimum discharge requirement. In electric precipitator and gas approach place mounting guiding board, it is possible to regulate the assignment of traffic of flue gas, but existing flow deflector is installed position and is fixed, its water conservancy diversion direction can not regulate, if there is the situation of assignment of traffic inequality between electric field, refitting can only be removed, cause claim for eot, waste of material.
Summary of the invention
The purpose of this utility model is to provide a kind of adjustable flue gas flow guiding device of wet electrical dust precipitator, so that being regulated in the water conservancy diversion direction of flue gas.
The adjustable flue gas flow guiding device of the utility model, it is made up of bracing frame and flow deflector, support frame as described above stretches bar and at least one pair of diagonal brace bar is formed by connecting by a grooved column and at least one pair of are flat, and is arranged on the gas approach position of wet electrical dust precipitator by grooved column; The two side putting down one end and grooved column of stretching bar is connected by described one respectively; The lower end of diagonal brace bar is connected the two side of grooved column by described one respectively, and upper end connects that a described couple is flat stretches bar respectively, and described flow deflector is fixed on two and flat stretches on bar; On the two side of described grooved column, vertical array has multiple adjustment hole, changes the horizontal angle of inclination �� of the adjustable flow deflector of adjustment hole that diagonal brace bar correspondence connects.
Adjustable flue gas flow guiding device comprises multiple bracing frame of shared same grooved column and multiple flow deflectors of correspondence.
Described grooved column is U-steel, described flat stretches bar and diagonal brace bar is angle steel.
In support frame as described above, U-steel, the flat each tie point stretched between bar or diagonal brace bar are all with bolts.
Described flow deflector is placed in two and flat stretch on bar and be connected and fixed with the flat bar of stretching of bolt and two.
The adjustable flue gas flow guiding device of above-mentioned wet electrical dust precipitator can according to the needs of air flow method in electric precipitator, conveniently the horizontal angle of inclination of each flow deflector is regulated respectively, flue gas assignment of traffic between wet electrical dust precipitator internal electric field is made to keep uniform and stable, it is ensured that the pollutent minimum discharge in flue gas. This apparatus structure is simple, and easy for installation, cost is low.
Accompanying drawing explanation
Fig. 1 represents the wet electrical dust precipitator structural representation that adjustable flue gas flow guiding device is housed.
Fig. 2 is the structural representation of adjustable flue gas flow guiding device.
Fig. 3 is that the A of Fig. 2 is to schematic diagram.
In figure, 1 flue gas flow guiding device, 2 flow deflectors, 3 flat stretch bar (flat hade steel), 4 diagonal brace bars (diagonal brace angle steel), 5 grooved columns (U-steel column), 6 adjustment holes, 7,8,9,10 bolt, 11 wet electrical dust precipitators, 12 electrodes, 13 flue gas inlet tubes, 14 smoke outlet tubes, 15 ash buckets.
Embodiment
As shown in Figure 1, electrode 12 is equipped with in wet electrical dust precipitator 11 inside, and bottom is provided with ash bucket 15. Flue gas from flue gas inlet tube lead to into, in wet electrical dust precipitator 11, the water smoke that flue gas contains and grit are adsorbed and be gathered into dust-containing liquid and drip by electrode 12, dust-containing liquid drops in action of gravity and falls to separated collection in ash bucket 15, and the flue gas after purification then discharges from the smoke outlet tube 14 of wet electrical dust precipitator 11. In the inner of flue gas inlet tube 13, adjustable flue gas guiding device 1 being housed, it comprises multiple flow deflector, with certain obliquity, flue gas is carried out water conservancy diversion respectively, makes flue gas assignment of traffic in wet electrical dust precipitator 11 evenly reasonable. The structure of adjustable flue gas flow guiding device 1 will be described further below.
See Fig. 2 and Fig. 3, adjustable flue gas flow guiding device is made up of flow deflector 2 and bracing frame, wherein, bracing frame comprises grooved column in a grooved column 5(the present embodiment and adopts U-steel, call U-steel column 5 in the following text), one to diagonal brace bar in diagonal brace bar 4(the present embodiment adopt angle steel, call diagonal brace angle steel 4 in the following text) and one stretch flow deflector union lever in bar 3(the present embodiment adopt angle steel to flat, call flat hade steel 3 in the following text); The two side of U-steel column 5 all has multiple adjustment hole 6; The left end of one pair of flat hade steel 3 with bolt 7 respectively two side with U-steel column 5 be connected; The lower end of one pair of diagonal brace angle steel 4 is connected by corresponding adjustment hole 6 with the two side of U-steel column 5 respectively with bolt 8, and upper end is connected with flat hade steel 3 with bolt 9; So far, diagonal brace angle steel 4 is constituted a diabolo bracing frame in the zygomorphy of U-steel column 5 by flat hade steel 3 and by one, and flow deflector 2 is placed on pair of horns steel 3, and is fixedly connected with angle steel 3 by bolt 10.
