Description
Technical Field
The invention relates to the technical field of waste gas treatment, in particular to a flue gas desulfurization waste gas treatment device.
Background
The sulfur dioxide in the flue gas is acidic in nature and can be removed from the flue gas by reaction with a suitable alkaline substance. The most commonly used alkaline materials for flue gas desulfurization are limestone, quicklime and slaked lime. Limestone is produced in a large quantity and is therefore relatively inexpensive, and both quicklime and slaked lime are produced from limestone by heating. Other basic substances such as sodium carbonate (soda ash), magnesium carbonate and ammonia are sometimes used. The alkaline material used reacts with the sulphur dioxide in the flue gas to produce a mixture with sulphate (depending on the alkaline material used, the salts may be calcium, sodium, magnesium or ammonium salts). The ratio between sulphite and sulphate depends on the process conditions, in some processes all sulphite is converted to sulphate. The reaction between sulphur dioxide and the alkaline substance takes place either in an alkaline solution (wet flue gas desulfurization technique) or on a wet surface of a solid alkaline substance (dry or semi-dry flue gas desulfurization technique).
In wet flue gas desulfurization systems, a basic substance (usually an alkali solution, more often a slurry of alkali) is encountered with the flue gas in a spray tower. Sulfur dioxide in flue gas dissolves in water to form a dilute acid solution, which then reacts with the alkaline species dissolved in the water. The reaction product and sulfate salts precipitate from the aqueous solution depending on the relative solubility of the various salts present in the solution. For example, calcium sulfate is relatively poorly soluble and therefore prone to precipitation; the solubility of sodium sulfate and ammonium sulfate is much better. In dry and semi-dry flue gas desulfurization systems, either the flue gas is injected into the flue gas stream through a bed of alkaline absorbent, or a solid alkaline absorbent is contacted with the flue gas. In either case, sulfur dioxide reacts directly with the solid alkaline material to form the corresponding sulfite and sulfate salts. In order for this reaction to proceed, the solid alkaline material must be quite loose or rather finely divided. In a semidry flue gas desulfurization system, water is added to the flue gas to form a liquid film on the surface of the alkaline substance particulate matter, and sulfur dioxide dissolves into the liquid film, accelerating the reaction with the solid alkaline substance.
According to Chinese patent publication No. CN115283406A, relates to the field of organic waste treatment and recovery, in particular to organic waste treatment equipment. The method comprises the following steps: the reaction tower is arranged in a vertical state and comprises a crushing cylinder, a separation cylinder and a liquid accumulation cylinder which are sequentially arranged from top to bottom; the gas separation mechanism is arranged beside the crushing barrel and fixedly connected with the crushing barrel, and can treat waste gas in the organic waste; the supporting mechanism is connected with the crushing cylinder and the gas separating mechanism and plays a role in supporting; the solid-liquid separation mechanism is connected with the crushing barrel and arranged inside the crushing barrel, the solid-liquid separation mechanism can perform solid-liquid separation treatment on organic waste, the solid-liquid separation mechanism comprises a filter disc, two cleaning brushes and a plurality of crushing cutters, the crushing cutters are arranged at equal intervals along the axial direction of the crushing barrel, the long edges of every two adjacent crushing cutters are mutually perpendicular, the filter disc is arranged at the lower part of the separation barrel, and the two cleaning brushes are respectively arranged on the upper side and the lower side of the filter disc and are mutually perpendicular.
At present, flue gas desulfurization exhaust treatment device is when using, because the restriction of big straight tube structure, can't realize high contact desulfurization and spray the operation, can't improve the degree of combining with sulfur dioxide to it is relatively poor to cause the actual effect of desulfurization, consequently needs an equipment to improve it to above-mentioned problem.
