Description

Defoaming device and absorption tower

Technical Field

The embodiment of the application relates to the technical field of environmental protection, in particular to a defoaming device and an absorption tower.

Background

More than 80% of coal in China is converted into energy in other forms in a direct combustion mode, and SO generated by coal combustion₂Is a major source of atmospheric pollution. Flue gas desulfurization by controlling SO₂The main measure of pollution, and the wet flue gas desulfurization technique is widely adopted as the most mature and effective mainstream technique.

An absorption tower is a device that performs an absorption operation. The liquid-gas phase contact state can be divided into three types. The first type is a plate tower, a bubbling absorption tower and a stirring bubbling absorption tower, wherein gas is dispersed in a liquid phase in a bubble form; the second type is an ejector, a venturi, a spray tower in which liquid is dispersed in a gas phase in the form of droplets; the third type is a packed absorption column and a falling film absorption column in which liquid contacts with a gas phase in a film-like motion. The gas-liquid two-phase flow mode in the tower can be countercurrent or cocurrent. The countercurrent operation is usually adopted, namely the absorbent is added at the top of the tower and flows from top to bottom, the absorbent is contacted with gas flowing from bottom to top, liquid absorbing the absorbent is discharged from the bottom of the tower, and purified gas is discharged from the top of the tower.

The absorption tower is used as the most important reaction equipment in wet desulphurization, and the internal gypsum slurry state is complex in the operation process. Factors such as the influence of water in the slurry on the surface tension of the slurry, the disturbance of the input of a stirrer and a circulating pump on the slurry, the blowing of oxidizing air, ultrafine particles carried in the slurry after dust removal by a bag-type dust remover and the like can cause the gypsum slurry to generate a large amount of bubbles, and the foaming of the gypsum slurry in an absorption tower is a common problem in the operation of various desulfurization devices. The generation of a large amount of bubbles on the liquid surface of the tower forms a false liquid level, which easily causes that the liquid containing bubbles flows back to the flue at the inlet of the absorption tower, and seriously causes the fault tripping of a draught fan to influence the safe operation of a generator set.

At present, the main means for eliminating bubbles on the liquid surface of the absorption tower is to manually spray a defoaming agent or manually wash the foam on the ground after the foam overflows. Therefore, the long-term manual spraying of the defoaming agent not only increases the operation cost, but also adversely affects the operation of the desulfurization system.
