Rotary spraying assembly of desulfurization column

Abstract

The invention relates to a rotary spraying assembly of a desulfurization column, belonging to the technical field of desulfurization equipment. The rotary spraying assembly comprises transverse supports and longitudinal supports, wherein the transverse supports and the longitudinal supports are staggerly arrayed and arranged in a grid shape; spraying assemblies are arranged between adjacent transverse supports or longitudinal supports; a plurality of groups of the spraying assemblies are arranged and are directly connected by water pipes; each spraying assembly comprises a shell, a rotating assembly arranged inside the shell and a spraying unit thereof; each shell is in the shape of a hollow cylinder; two sides of each shell are provided with matching detachable cover bodies; each sprayingunit comprises a plurality of groups of spraying pipelines; each spraying pipeline is provided with a plurality of spraying holes; and each spraying hole is provided with a matching atomizing nozzle.The rotary spraying assembly of the invention can quickly realize all-round spraying treatment on sulfur-containing substances inside the desulfurization column, avoids secondary pollution and reduces cost.

Description

technical field [0001] The invention relates to a rotating spray assembly of a desulfurization tower in the field of desulfurization equipment. Background technique [0002] In recent years, China's flue gas desulfurization industry has developed rapidly, and a considerable number of flue gas desulfurization facilities have been built; with a large number of limestone / gypsum wet flue gas desulfurization devices put into operation, desulfurization devices have become an important part of environmental protection equipment operators. The level of operation and management of the main devices managed directly affects the economy and safety of production; a large number of environmental monitoring data show that due to the increase of acidic substances in the atmosphere, cloud water over most parts of the earth is becoming acidic, such as If left unchecked, the area of ​​the acid rain area will continue to expand, and the harm to humans will also increase day by day; it has been ...

[0002] In recent years, China's flue gas desulfurization industry has developed rapidly, and a considerable number of flue gas desulfurization facilities have been built; with a large number of limestone / gypsum wet flue gas desulfurization devices put into operation, desulfurization devices have become an important part of environmental protection equipment operators. The level of operation and management of the main devices managed directly affects the economy and safety of production; a large number of environmental monitoring data show that due to the increase of acidic substances in the atmosphere, cloud water over most parts of the earth is becoming acidic, such as If left unchecked, the area of ​​the acid rain area will continue to expand, and the harm to humans will also increase day by day; it has been confirmed that sulfur dioxide and nitrogen dioxide in the atmosphere are the main substances that form acid rain; sulfur dioxide and nitrogen dioxide in the atmosphere are mainly It comes from the combustion of coal and oil; according to statistics, the world emits about 100 million tons of sulfur dioxide and about 50 million tons of nitrogen dioxide into the atmosphere every year. Therefore, acid rain is mainly caused by human production activities and life; the components of acid rain measured in the United States are , sulfuric acid accounts for 60%, nitric acid accounts for 32%, hydrochloric acid accounts for 6%, and the rest is carbonic acid and a small amount of organic acid; and as mentioned above, the spray device of the traditional desulfurization tower can no longer meet the current demand, and the traditional spray The atomization of the device is uneven, and the atomization effect cannot be guaranteed. Even if the atomization effect can be guaranteed, the spraying is uneven and the effect is not good.
