Problems solved by technology
These sulfur dioxide, nitrogen oxides and fine particles are the main culprits in the formation of smog, which will greatly affect the health of residents and even threaten their lives. Harmful gases and solid particles, but the elimination effect is not significant enough and still needs to be improved. In addition, the existing flue gas desulfurization and denitrification devices generally have poor dust wetting effect, self-flushing cannot be realized in the tower, and the dust concentration of the flue gas exiting the tower is 120mg / m 3 The above, and there are disadvantages of complex structure, high investment cost, high operating cost, and large floor space

The utility model relates to a desulfurization tower with a miniature wet dust collector, which belongs to the technical field of desulfurization equipment. The present invention aims to solve the common problems that existing flue gas desulfurization and denitrification devices generally have poor soot wetting effect, self-flushing cannot be realized inside the tower, and the dust concentration of flue gas exiting the tower is above 120 mg / m3. The middle part of the desulfurization tower of the present invention is provided with three groups of self-flushing sprinklers, each group of self-flushing sprinklers is connected to the water tank through a spray pipeline, a water pump is arranged on the spray pipeline, and an electromagnetic on-off valve is arranged on the water pump ;The miniature wet dust collector is located under the three sets of self-flushing sprinklers. Several lightning deflectors of the miniature wet dust collector are arranged horizontally and are fixed in the desulfurization tower through the installation frame. The adjacent two lightning The air flow channel is formed between the lightning deflectors, and the lightning deflectors are provided with micro nozzles. The present invention has a good dust wetting effect, and the dust concentration of the tower flue gas is within 50 mg / m3, realizing the self-flushing function of the desulfurization tower.
Description
technical field [0001] The invention relates to a desulfurization device, in particular to a desulfurization tower with a miniature wet dust collector, and belongs to the technical field of desulfurization and denitrification equipment. Background technique [0002] The exhaust gas after coal combustion in traditional coal-fired power plants is directly discharged into the atmosphere after dust removal, desulfurization and denitrification approach or even meet the emission standards, and the exhaust gas contains sulfur dioxide, nitrogen dioxide, Harmful gases such as nitric oxide and fine solid impurity dust such as fly ash with light specific gravity and small particles. These sulfur dioxide, nitrogen oxides and fine particles are the main culprits in the formation of smog, which will greatly affect the health of residents and even threaten their lives. Harmful gases and solid particles, but the elimination effect is not significant enough and still needs to be improved. I...
