High-efficiency desulfurization and dedusting technology and equipment thereof

Abstract

The invention discloses a high-efficiency desulfurization and dedusting technology. The technology comprises the following steps: 1. flue gas heat exchange; 2. flue gas desulfurization; 3. reaction water treatment; 4. aqueous solution monitoring; 5. water recycling; 6. flue gas dedusting; 7, flue gas heating; and 8, smoke evacuation. The invention also discloses high-efficiency desulfurization anddedusting equipment. The high-efficiency desulfurization and dedusting equipment comprises a smoke exhaust port, the smoke exhaust port is connected to a heat exchange box, a heat exchange plate is arranged in the heat exchange box, a desulfurization tower is connected to a smoke inlet zone, a sprinkler head is arranged on the top of the desulfurization tower, the desulfurization tower is connected with rotating blades through a rotating shaft, the desulfurization tower is connected to a dust removal chamber through a smoke outlet pipe, the desulfurization tower is connected to a lime pool and an alkaline pool through a sedimentation tank, the alkaline pool is provided with a pH detector, and the alkaline pool is connected to the sprinkler head through a water pipe. The technology realizes recycling through the reaction water in the heat exchange box and the desulfurization tower to avoid secondary pollution and improve energy utilization rate; the rotating blade in the desulfurization tower increases the efficiency of a desulfurization reaction, so that the sulfide in the flue gas reacts thoroughly, and the erosion of the inner wall by the flue gas is reduced.

Description

technical field [0001] The invention relates to the technical field of flue gas treatment, in particular to a high-efficiency desulfurization and dust removal process and equipment. Background technique [0002] In the process of industrial production, industrial flue gas will be produced. These flue gases contain a large number of harmful substances, among which sulfide is the most significant. Sulfur compounds are released into the atmosphere along with the flue gas to cause acid rain and environmental pollution. Contains a large amount of dust and harmful particles, which are released into the atmosphere and cause pollution to the atmosphere. Now the flue gas emitted by industrial production will be discharged into the atmosphere after a certain treatment. The current treatment is generally divided into two types: wet method and dry method. Now The most commonly used method is wet desulfurization and dust removal. The sulfide in the flue gas reacts with the solution in th...
