Abstract
The utility model discloses a device for collecting and discharging bubbles of a desulfuration absorption tower. The device comprises a bubble collector and a bubble discharge pipe, an exhaust gas discharge pipe and a washing pipe. The bubble collector is arranged inside the desulfuration absorption tower, the bubble discharge pipe, the exhaust gas discharge pipe and the washing pipe are arranged outside the desulfuration absorption tower, a bubble collector inlet is arranged in the bubble collector, and an outlet of the bubble collector is connected with the bubble discharge pipe, the exhaust gas discharge pipe and the washing pipe outside the desulfuration absorption tower respectively. When bubbles are produced in the desulfuration absorption tower during operation, an operation liquid level of the desulfuration absorption tower is raised to the highest overflow liquid level, and bubbles in the desulfuration absorption tower enter the bubble collector to be discharged out. According to the device, as positive pressure operation exists inside the absorption tower, bubbles are easy to discharge out of the absorption tower, phenomena of desulfurization efficiency decreases, by-product dehydration difficulties, large slurry displacement and boiler-stop processes caused by too many bubbles in the absorption tower are avoided, and a desulfuration device is maintained to operate safely and stably.
Description
Technical field
The utility model relates to a kind of foam of desulfuration absorbing tower and collects tapping equipment.
Background technology
Wet process of FGD is the most frequently used flue gas desulfurization technique in coal-burning power plant.Desulfurizer is in running, and foam often appears in the absorption tower, and the high-order floss hole on existing absorption tower has only overflow mechanism, and the import of overflow mechanism is designed to below the minimum operation liquid level of absorption tower, therefore leans on overflow mechanism to be difficult for discharging absorption tower inner foam.Combustion-supporting and the absorption tower long-time running of boiler start/ stop fuel oil is prone to produce foam, and the untimely discharging of these foams is prone to cause that desulfuration efficiency descends, the gypsum dehydration difficulty, even the stoppage in transit boiler is handled etc.
The gas that forms foam is mainly the CO of flue gas, oxidation air, desulfurization generation
2Deng, when boiler employing fuel ignition, combustion-supporting, the steady combustion of oil gun, during the deduster operation exception; Also can produce significant foam; These floatation of foam can not be eliminated even the foam that some foam such as fuel oil produce takes to add antifoaming agent on the liquid level of absorption tower, and foam can hinder SO
3 2-Oxidation reaction, reduction desulfuration efficiency for the desulphurization system of no bypass flue, directly influence the set steady operation, need load down operation even blowing out to handle in case of necessity.
The utility model content
The utility model provides a kind of foam of absorption tower to collect and tapping equipment for solving the problems of the technologies described above.When foam appears in the absorption tower operation, open foam valve and waste gas valve, the absorption tower inner foam is discharged outside the tower.
To achieve these goals, the utility model adopts following technical scheme.
A kind of foam of desulfuration absorbing tower is collected tapping equipment, comprises the foam trap and outer foam drainage pipe, exhaust pipe and the cleaning hose of desulfuration absorbing tower that are positioned at desulfuration absorbing tower; Have the foam trap import on the foam trap, the outlet of foam trap links to each other with outer foam drainage pipe, exhaust pipe and the cleaning hose of desulfuration absorbing tower respectively.
As the further improvement of the utility model, the horizontal line of foam trap import is higher than the highest overflow liquid level in the desulfuration absorbing tower.
Foam trap import top is designed with rain shade, and the area of rain shade prevents spraying layer spray slurries entering foam trap down greater than the area of foam trap, and rain shade can be oblique retaining formula, ridge type etc.
Foam trap import upper edge can be designed as zigzag, waveform or comb teeth shape, makes foam get into foam trap easily.
The projection of shape of foam trap can be rectangle, semicircle, circle or oval.
Be respectively equipped with foam drainage valve, exhaust valves and cleaning hose valve on foam drainage pipe, exhaust pipe and the cleaning hose.
Also be provided with rain cover on the exhaust pipe.
When operation finds that desulfuration absorbing tower has foam to produce, improve desulfuration absorbing tower operation liquid level to the highest overflow liquid level.Open foam drainage valve and exhaust valves, the foam in the desulfuration absorbing tower gets into foam trap and discharges outside the tower, and foam drainage finishes, and closes foam drainage valve and exhaust valves.When foam drainage pipe or exhaust pipe obstruction, close foam drainage valve and waste gas valve, open the cleaning hose valve, flushing finishes, and closes the cleaning hose valve.
The beneficial effect of the utility model is; Because in the desulfuration absorbing tower is operation under positive pressure; Foam is discharged outside the desulfuration absorbing tower easily; Avoid keeping the desulfurizer safe and stable operation because of the desulfuration absorbing tower foam too much causes desulfuration efficiency decline, byproduct dehydration difficulty, replaces slurries or blowing out processing in a large number.
