Acidic crystallization device for desulfurization and denitrification equipment

Abstract

The invention discloses an acidic crystallization device for desulfurization and denitrification equipment. The device comprises a desulfurization and denitrification tank, a spraying assembly, gas guiding and mixing assemblies and a gas purifying treatment assembly, an acidification mechanism and a liquid supplementing box which are communicated with each other are arranged at the bottoms of the two sides of the desulfurization and denitrification tank respectively, a flow guide table is arranged at the edge of the bottom in the desulfurization and denitrification tank, the inner side of the flow guide table is provided with hemispherical flow guide seats which are matched with each other, the bottom of the interior of each hemispherical flow guide seat is provided with a fan, and the two sides of the top of the desulfurization and denitrification tank are provided with breather pipes which are communicated with each other. Through mutual cooperation of the gas guiding and mixing assemblies, flue gas fed into the desulfurization and denitrification tank is promoted to be dispersed and discharged from a communicating pipe and a through opening under spiral flow guide of an inner spiral flow guide pipe, and meanwhile, a stirring effect is achieved under rotation of the communicating pipe, so that the flue gas is treated more uniformly under operation of the spraying assembly, and the mixing precision and effect of wet-type treatment of the flue gas are improved.

Description

technical field [0001] The invention relates to the technical field of desulfurization and denitrification, in particular to an acid crystallization device used for desulfurization and denitrification equipment. Background technique [0002] Coal-fired boilers refer to boilers whose fuel is coal.

[0002] Coal-fired boilers refer to boilers whose fuel is coal. After the heat of coal is converted, steam is generated for industrial production, but not all of the heat is effectively converted, and some of the heat is consumed without work, so there is an efficiency problem. The use of coal-fired boilers The scope of the coal-fired boiler is very wide. When the coal-fired boiler is in use, it will produce a large amount of flue gas, and the particles, sulfur-containing compounds and nitrogen-containing compounds contained in the flue gas are all substances that pollute the atmosphere. The smoke and dust problem of coal-fired boilers has always been troubled. these people;

[0003] The current treatment methods for flue gas from coal-fired boilers are mostly wet treatment methods. However, in the actual treatment of flue gas, a large amount of flue gas needs to be transported, and the flue gas contains a lot of dust and harmful substances, and it is easy to concentrate and produce condensation. Agglomeration will increase the adhesion with the conveying mechanism and reduce the conveying efficiency of the flue gas, and when the flue gas is mixed with the wet treatment water, the flue gas may wander around and cannot fully contact the water, thereby reducing the flue gas The diversion of the gas treatment increases the treatment time and waiting time. After a single treatment of the flue gas, the odor and sulfur gas may still remain, which makes the single treatment effect of the flue gas of the device fail to meet the ideal requirements and reduces the treatment effect of the flue gas. , reducing the availability of the device
