Dust and water removal unit special for LD type wet desulphurization

Abstract

The invention belongs to the technical field of design environmental protection, and particularly relates to a dust and water removal unit special for LD type wet desulphurization, and the following scheme is provided: the dust and water removal unit comprises a water stopping and collecting ring, the inner wall of the water stopping and collecting ring is fixedly connected with a shaping suction port, the outer wall of the shaping suction port is fixedly connected with a connecting ring, and the inner wall of the connecting ring is fixedly connected with an inlet flange; an inlet flue gas constant-speed line is arranged on the inner wall of the water stopping and collecting ring, a flue gas transition flue is arranged on the inner wall of the inlet flange, an outer ring is installed on the inner wall of the flue gas transition flue, and an inner ring is arranged in the outer ring. By arranging the flue gas transition flue, the treatment frame, the flow guide cover and the bent activated carbon adsorption plates, after flue gas enters the flue gas transition flue, the flue gas enters the treatment frame through the flow guide cover, and under the sealing and guiding action of the sealing plate, the flue gas can only pass through all the bent activated carbon adsorption plates; and the bent activated carbon adsorption plate prolongs the time that the flue gas is located in the treatment frame, and the flue gas adsorption treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of design and 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 demisters and roof ridge plus tube composite demisters can meet the demisting effect of 70mg / m3. To further improve the demisting standard, wet electrostatic precipitators need to be added. Wet electrostatic precipitators will lead to equipment costs and usage. The cost and energy consumption are greatly increased, and it is very difficult for users to implement. The status quo of desulfurization in the society urgently needs new solutions.
