Dedusting and desulfurization integrated machine

Abstract

The invention discloses a dedusting and desulfurization integrated machine. The machine comprises an inlet flue, a filter chamber, a dust chamber, a desulfurizing tower, an outlet flue and a circulating pool, wherein the inlet flue is communicated with the filter chamber; the filter chamber is communicated with the dust chamber through a first flue gas passage; the dust chamber is communicated with the desulfurizing tower through a second flue gas passage; a uniformly distributing board is arranged in the second flue gas passage; the outlet flue is formed in the top of the desulfurizing tower; a circulating hole is formed in the bottom of the desulfurizing tower and communicated with the circulating pool through a circulating pipeline; the circulating pool is connected with a circulating pump; and the circulating pump is connected with the desulfurizing tower through a liquid inlet pipe. The machine disclosed by the invention has the advantages that the dedusting and the desulfurization can be integrally completed; the dedusting effect is good; a bag dedusting method is not adopted, so that the operating cost is saved; the flue gas is stable and uniform; the desulphurization efficiency is high; scale cannot be easily formed in the desulfurizing tower and the pipeline; the machine is simple and convenient to operate; and the system can be stably operated in a long term.

Description

【Technical field】 [0001] The invention relates to the technical field of environmental protection equipment, in particular to the technical field of dust removal and desulfurization integrated machines. 【Background technique】 [0002] At present, the problem of environmental pollution has become a global social problem, especially air pollution, which has a wide range of harm, long time and deep harm. Air pollution is mainly caused by the exhaust gas emitted by the factory. During the production process of the factory, the billowing smoke carries pollutants such as dust and sulfur dioxide into the air. If the smoke has not been harmlessly treated, it cannot be directly discharged into the air. In the air, therefore, there is a dust removal device, which removes the smoke and dust in the flue gas. In addition, sulfur dioxide is one of the main pollutants in the atmosphere, and it is also an important indicator to measure whether the atmosphere is polluted. The control of sulf...

Problems solved by technology

First, the dust content in the flue gas is large and the cohesion is strong, which seriously reduces the desulfurization efficiency; second, when the flue gas enters the desulfurization tower, due to inertia, the gas is unevenly distributed in the tower, and the area facing the flue entrance The flow rate is high, which results in poor gas-liquid mass transfer effect and unstable airflow operation, which not only affects the desulfurization efficiency, but also affects the water removal effect of the demister; third, the gypsum produced by this method is in the desulfurization It is easy to consolidate in the equipment, which will block the desulfurization equipment and affect the use effect. In addition, the initial reaction speed of limestone is slow, which also has a certain impact on the desulfurization efficiency.
