Describe an exemplary embodiment of the present utility model below with reference to accompanying drawings in detail.
Fig. 1 shows according to the cooling high-temperature fume dehydration of an exemplary embodiment of the present utility model and the structural representation of water seal arrangement.Fig. 2 is along the sectional view of A-A line among Fig. 1.Fig. 3 is along the sectional view of B-B line among Fig. 1.Fig. 4 is along the sectional view of C-C line among Fig. 1.Fig. 5 is along the sectional view of D-D line among Fig. 1.Fig. 6 is along the sectional view of E-E line among Fig. 1.Fig. 7 is along the sectional view of F-F line among Fig. 3.Fig. 8 is along the sectional view of G-G line among Fig. 3.Fig. 9 is along the sectional view of H-H line among Fig. 7.
As shown in Figure 1, in this exemplary embodiment, cooling high-temperature fume dehydration and water seal arrangement comprise tower body 1, inlet pipe 2, air outlet 3, water spray unit 4, dewatering unit 5, water filling port 6, water port 7a, 7b, scavenging duct 8, manhole 9a, 9b, 9c, 9d, stiffening plate 10, inspection platform 11, overflow port 12.
Wherein, inlet pipe 2 be arranged on tower body 1 the top and with tower body 1 internal communication; Water spray unit 4 is arranged on the inlet end of inlet pipe 2; Dewatering unit 4 is arranged between the outside wall surface of the inner-wall surface of tower body 1 and inlet pipe 2, and is positioned at the top, outlet side of inlet pipe 2; Air outlet 3 is arranged on the top of tower body, and is positioned at the top of dewatering unit 4.High-temperature flue gas (for example, the blast furnace purified gas) enters tower body 1 inside through the water smoke of the water spray unit 4 ejection back that cools from inlet pipe 2, floats then and dewaters by dewatering unit 5,3 emits from the air outlet at last.In addition, for the effect that realizes sealing, need usually in the tower body 1 to inject suitable liquid (as water) to appropriate depth.Here, when this device works better, the liquid level in the tower body 1 is no more than the outlet side of inlet pipe 2, and at this moment, the liquid of tower body 1 bottom plays the effect that prevents that furnace gas is excessive; And when this device needs maintenance, liquid level in the tower body is higher than the outlet side (being the dotted line place of the along continuous straight runs among Fig. 1) of inlet pipe 2, the pressure that utilizes liquid level to produce seals the gas in the inlet pipe 2, play the effect that cuts off water seal, the insertion level of inlet pipe 2 is determined according to gaseous tension.
As shown in Figure 2, water spray unit 4 comprises the water spray arm on a plurality of inlet ends that are distributed in inlet pipe 2, and the shower nozzle of water spray arm is positioned at inlet pipe 2.Preferably, the setting angle of a plurality of water spray arms is along the radial direction of inlet pipe 2.In this exemplary embodiment, water spray unit 4 comprises 11 water spray arms, and the water spray arm is around the inlet end setting of inlet pipe 2, and evenly distribution.Because the setting angle of water spray arm is along the pipeline radial direction, thereby the water outlet direction of the shower nozzle of water spray arm is all perpendicular to the air flow line in the inlet pipe 2, water smoke ejection back with air-flow at the bottom of action of gravity following enters tower, thereby can prolong low temperature water smoke to the cooling effect time of high-temperature flue gas, unit water yield cooling-down effect is better.
To shown in Figure 9, in this exemplary embodiment, dewatering unit 5 is welded into the multilayer reticulated structure by multiple steel construction piece (for example angle steel, joist steel) as Fig. 1, Fig. 3, Fig. 7, and gathers between the outer wall of the inwall of tower body 1 and water inlet pipe 2.Because dewatering unit 5 is arranged on the top of tower body 1, the direction that makes air-flow enter dewatering unit at the bottom of the tower is the antigravity direction, and gas velocity evenly and is relatively slowed down, and has strengthened dehydrating effect.
Extremely shown in Figure 6 as Fig. 1, Fig. 3, multiple structure of the prior art can also be set on the tower body 3, for example, water filling port 6 and overflow port 12 are set on tower body top, so that the liquid level in the tower body 1 is accurately controlled, in the bottom of tower body water port 7a, 7b are set, under situations such as maintenance, the liquid in the tower body 1 is discharged; In addition, this device can also comprise scavenging duct 8, and scavenging duct is communicated with inner chamber and the external air source (for example, nitrogen) of inlet pipe 2 when maintenance, so that the gas (for example, coal gas) in the inlet pipe 2 is fully discharged; In addition, this device can also comprise being arranged on and repairs manhole 9a, 9b, 9c, 9d into usefulness for manual inspection on the tower body, is arranged on described manhole with the stiffening plate 10 of strengthening action is played in tower body 1 junction, and is arranged on the interior structures such as inspection platform 11 of tower body.Those skilled in the art can also arrange by-pass valve control at need position or the pipeline place of cooling high-temperature fume dehydration of the present utility model and water seal arrangement, control effectively with the work to this device, do not repeat them here.
Cooling high-temperature fume dehydration of the present utility model and water seal arrangement are widely used in cooling, dehydration and the water shut off treatment of various high-temperature flue gas, for example, blast furnace purified gas, coke-oven gas etc., when being applied to the processing of blast furnace purified gas, disposable realization blast furnace purified gas enters cooling, dehydration and the water shut off treatment operation that needs before the pipe network.
In sum, cooling high-temperature fume dehydration of the present utility model and water seal arrangement, in a device, realized cooling, dehydration and water seal resistance simultaneously, reduced construction investment and floor space, and have characteristics such as simple in structure, easy to operate, practical, that treatment effect is good.
Although above by having described the utility model in conjunction with exemplary embodiment, but those skilled in the art should be clear, under the situation that does not break away from the spirit and scope that claim limits, can carry out various modifications and change to exemplary embodiment of the present utility model.
