LD-type wet desulfurization special-purpose dust and water removal unit

Abstract

LD type wet desulfurization dedicated dedusting and water removal unit, applied to the outlet at the center of the top of the desulfurization tower, including water stop and water collection ring, plastic suction port, flue gas transition flue, inlet flange, outer ring, inner ring, gas and water capture The tank, the flushing water pipeline, the return pipe in the return tower area and the outlet flange, the air flow is discharged through the outlet of the desulfurization tower into the shaping suction port, and the air flow is integrated. During this process, a mushroom-shaped inlet flue gas isokinetic line will be formed at the shaping suction port. The flue gas enters a flat rectangular "S" channel, and the channel is divided into double-layer or multi-layer "S" channels with "S"-shaped partitions. Each channel is divided into a positive semicircle (210°) and an anti-semicircle. (150°). It has the advantages of simple structure and not easy to block, and is compatible with the original folding plate demister. The above structure shows that the efficiency of suctioning concentrated wet airflow is significantly higher than that of simply recovering liquid.

Description

technical field [0001] The invention relates to the technical field of design and design of environmental protection, in particular to an LD-type wet desulfurization special dust and water removal unit. Background technique [0002] In the limestone (lime) wet desulfurization process, due to its mature technology and high desulfurization efficiency (over 98%), it has become more and more mainstream. Another subject that comes with craftsmanship. At present, the commonly used folding plate type demister and roof plus tube type composite demister can meet the requirements of 70mg / m 3 Defog effect, further improving the demist standard needs to increase the wet electrostatic precipitator. The wet electrostatic precipitator will greatly increase the equipment cost, use cost and energy consumption, and it is very difficult for users to implement. The status quo of desulfurization in the society urgently needs new solutions. [0003] Invention content: [0004] The purpose of ...
