Description
Technical field
The utility model relates to a kind of outer foam of desulfuration absorbing tower that is installed in and collects tapping equipment automatically.
Background technology
Wet process of FGD is to use maximum sulfur removal technologies, accounts for more than 85% of thermal power plant installed capacity.Wet process of FGD all has the absorption tower, and foam often appears in the absorption tower in running, and absorption tower operation does not at present detect foamite system automatically, and foam also is difficult for discharging outside the tower.The untimely discharging of these foams is prone to cause desulfuration efficiency decline, gypsum dehydration difficulty, absorption tower foam to pour in down a chimney gas approach, causes system jams even device damage.
The gas that forms foam is mainly the CO of flue gas, oxidation air, desulfurization generation
2Deng, when boiler adopts fuel ignition, combustion-supporting, the steady combustion of oil gun, during the deduster operation exception, also can produce significant foam, these floatation of foam are on the liquid level of absorption tower, and foam can hinder SO
3 2-Oxidation reaction, reduction desulfuration efficiency directly influence the set steady operation, need load down operation even blowing out to handle in case of necessity.In the prior art, the equal non-foam of desulfuration absorbing tower detects tapping equipment automatically, when foam occurring, leans on absorption tower overfall observation, adopts to add antifoaming agent, so has slurries in the discharging of foam.
The utility model content
The utility model is for solving the problems of the technologies described above, and provides that a kind of absorption tower foam detects automatically, collection and tapping equipment.When foam appears in the absorption tower operation, can detect foam automatically, open foam valve and waste gas valve automatically, the absorption tower inner foam is discharged outside the tower.
To achieve these goals, the utility model adopts following technical scheme.
The outer foam of the desulfuration absorbing tower of the utility model is collected tapping equipment automatically, comprises foam trap, foam detecting device, foam drainage pipe, exhaust pipe, cleaning hose and electric control gear; Foam trap one end connects desulfuration absorbing tower, and the other end connects foam drainage pipe, exhaust pipe and cleaning hose, is respectively equipped with foam drainage tube valve, toxic emission tube valve and cleaning hose valve on said foam drainage pipe, exhaust pipe and the cleaning hose; Said foam detecting device is positioned at the foam trap top, and the output of foam detecting device is connected with the input of said electric control gear, and the output of said electric control gear is connected with foam drainage tube valve, toxic emission tube valve and cleaning hose valve respectively.
As the further improvement of the utility model, the foam trap bottom is equipped with the return duct that returns desulfuration absorbing tower.
The top of said foam trap has the installing hole that described foam detecting device is installed.
Said foam detecting device comprises electrode bar, base, lead-out wire, and wherein said base is installed in the foam trap top, and said electrode bar is fixed on the base, and passes installing hole.Adopt the sealing ring sealing between base and foam trap wall, electrode bar and the base, electrode bar and foam trap insulation.
Said exhaust pipe top is equipped with rain cover.
The operation principle of the utility model does; Foam detecting device can detect the absorption tower automatically and foam whether occur, when foam detecting device detects foam and occurs, sends signal to electric control gear; Electric control gear is opened foam drainage tube valve, toxic emission tube valve and cleaning hose valve automatically; Foam is discharged outside the tower automatically, and when lather collapse, the electric control gear by-pass valve control is closed automatically; Electric control gear can be devices such as single-chip microcomputer.The material that contains solid that the foam trap return duct can will get in the gatherer leans on the gravity effect to return the absorption tower, prevents that foam trap from stopping up, and simultaneously, the slurries amount of the foamover of discharge seldom.
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 can realize the automatic detection of foam in the desulfuration absorbing tower and collect discharging that prevent system jams, the raising desulfuration efficiency keeps the set steady operation.
