Problems solved by technology

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, to further improve 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

Abstract

The invention discloses a special dust and water removal unit for LD-type wet desulphurization. The device is applied to a central outlet in the top of a desulfurizing tower. The device comprises a water stop and water collection ring, a shaping suction port, a flue gas transition flue, an inlet flange, an outer ring, an inner ring, a gas-water trapping tank, a flushing water pipeline, a tower return area return pipe and an outlet flange. The airflow is discharged from the outlet of the desulfurizing tower and enters the shaping suction port to undergo shaping. In the process, a mushroom-shaped inlet smoke constant-speed line is formed at the shaping suction port, smoke enters a flat rectangular S-shaped channel, the interior of the channel is divided into two layers or multiple layers ofoverlapped S-shaped channels through S-shaped partition plates, and each layer of channel is divided into a positive semicircle (210 degrees) and a negative semicircle (150 degrees). The device has the advantages of being simple in structure and not prone to being blocked, meanwhile, the device is compatible with an original folded plate demister, and it can be seen through the structure that thetreatment efficiency of pumping and concentrating wet airflow is obviously improved compared with pure liquid recovery.

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. Invention content: [0003] The purpose of the pres...
