Description
Technical Field
The invention relates to the technical field of flue gas treatment, in particular to a novel weighing type ship-shaped ash bucket.
Background
With the continuous increase of coal consumption in China, the emission of sulfur dioxide and dust from fire coal is also increasing. The discharge amount of pollutants is the top of the world, so that the environmental pollution of China is becoming serious, the improvement of the dust removal technology of coal-fired facilities, the reduction of the discharge amount of smoke dust and the control of the discharge amount of sulfur dioxide become urgent needs of social and economic sustainable development, and the improvement is imperative.
The coal-fired sulfur dioxide control method can be divided into three categories: pre-combustion desulfurization, in-combustion desulfurization, and post-combustion desulfurization (flue gas desulfurization), wherein post-combustion desulfurization of flue gas is considered to control SO2The most effective way of contamination. As for the flue gas desulfurization technology, there are mainly 4 kinds of flue gas desulfurization processes that have been widely used at present: wet limestone/gypsum absorption (Wet-FGD), dry spray drying purification (SDA), in-furnace calcium spray post-humidification water activation (LIFAC), and circulating fluidized bed flue gas purification (CFB-FGD).
The circulating fluidized bed flue gas purification process is to add Ca (OH) into a desulfurizing tower2SO in powder and flue gas2And other constituents of the flue gas, e.g. SO3The acid gases of HCl, HF, etc. are fully contacted and mixed, and the atomized water sprayed at the inlet of the desulfurizing tower can reduce the flue gas temperature and ensure the optimal reaction condition, and can be sprayed at the inlet of the Ca (OH)2The surface of the particles forms a liquid phase. Ca (OH) in desulfurizing tower2The powder, flue gas and sprayed water are mixed thoroughly in suspension and passed through an excess of Ca (OH)2The powder is circulated for many times in the desulfurizing tower, and SO in the flue gas is enabled to be in a proper Ca/S ratio of 1.3-1.92、SO3And the acid gas can be fully absorbed, so that the high-efficiency desulfurization and the high-efficiency utilization of the desulfurizer are realized.
The residence time of the desulfurizer in the desulfurizing tower is short, most of newly added desulfurizer enters the rear dust remover from the outlet at the top of the desulfurizing tower along with flue gas, and the desulfurized fly ash collected by the dust remover contains a large amount of unreacted desulfurizer, so that the desulfurized fly ash needs to be returned to the desulfurizing tower for reuse by a set of material returning device, and the higher desulfurization efficiency is realized at the lower calcium-sulfur ratio. At present, the more common material returning device is directly combined with an air locking device by using an air chute. When the material returning device faces various working conditions in the use process, the ash discharge of the air locking device cannot be combined with the actual ash amount in the ash bucket, and the phenomenon that the ash of the individual ash bucket is discharged and the desulfurized ash in other ash buckets is accumulated and bridged can occur; meanwhile, the phenomena of uneven reaction of a boiler, an induced draft fan, a sintering machine and a desulfurizing tower caused by uneven ash discharge of a dust remover due to the fact that the amount of returned materials is small and large and the pressure difference of the desulfurizing tower is uncontrollable can occur.
A control process adopted by a circulating fluidized bed flue gas desulfurization system at present comprises the steps of ① judging the quantity of dust in a dust hopper through a material level switch on the dust hopper of a dust remover, when the height of the dust accumulated in the dust hopper reaches the position of a high material level, explaining that the quantity of the dust in the system exceeds the quantity required by the operation of the system, conveying the dust to a dust bin by the system, stopping the conveying of the system until the dust accumulation height is reduced to the position of the low material level, ② controlling the return quantity of the system by additionally arranging a metering device on a circulating dust conveying device.
