Description

Technical Field

[0001] The present application relates to the technical field of industrial waste gas treatment, and in particular to an industrial waste gas desulfurization, denitrification, dust removal and cleaning equipment for air pollution prevention and control. Background Art

[0002] Flue gas desulfurization and denitrification technology is a boiler flue gas purification technology used in chemical industries that produce a lot of nitrogen oxides and sulfur oxides. Nitrogen oxides and sulfur oxides are one of the main sources of air pollution, so the application of this technology has many benefits for environmental air purification;

[0003] After searching, the existing patent (publication number: CN202410487356.6) discloses industrial waste gas desulfurization, denitrification and dust removal equipment, including a treatment tube, the treatment tube is connected to two reaction tubes and an air inlet pipe, and the treatment tube is connected to a filter tank through a feed pipe and a drain pipe; it also includes a liquid level monitoring component, a first plugging component and a second plugging component, which are arranged in the treatment tube, and the waste gas can be dusted in the liquid inside the reaction tube to reduce the possibility of dust in the waste gas entering the reaction tube. The waste gas after dust removal enters the liquid layer inside the reaction tube to ensure that the gas is fully contacted and reacted with the desulfurization and denitrification liquid in the reaction tube. By setting a liquid level monitoring component, the discharge of the treatment tube can be automatically adjusted according to the liquid supply of the reaction tube to the treatment tube, and according to the movement of the liquid level monitoring component, the second plugging component can be opened according to the specific usage situation to drive the suspended impurities in the treatment tube to be discharged through the drain pipe along with the liquid level.

[0019] Technical effects and advantages of this application:

[0020] 1. Compared with the prior art, this kind of air pollution prevention and control industrial waste gas desulfurization, denitrification, dust removal and cleaning equipment can pre-treat the dust in the industrial waste gas, thereby reducing the pressure of subsequent desulfurization and denitrification work, making the industrial waste gas treatment cleaner, and can make the treated solution waste liquid cleaner, which is convenient for subsequent solution recovery and treatment. The waste gas generated by industrial production enters the dust removal equipment through the air intake pipe for dust removal. When the industrial waste gas enters the dust removal equipment, the dust in the waste gas is adsorbed by the dust suction rod, so that the dust in the waste gas is separated from the waste gas.

[0021] 2. Compared with the prior art, the dust removal and cleaning equipment for desulfurization and denitrification of industrial waste gas for air pollution prevention and control has a good dust absorption effect during dust removal, and can remove the dust from the dust collection equipment after absorbing too much dust, thereby reducing the subsequent cleaning and maintenance procedures. When the dust suction bag captures and adsorbs too much dust, the electrostatic generator and the electrostatic connecting rod connected thereto are powered off, so that the dust captured and adsorbed by the dust suction bag falls from the dust suction bag, and ventilation can be used to assist the dust on the dust suction bag to fall off. The active screw is driven by the opening and closing motor to rotate, and the active screw drives the adjacent transmission screw to rotate through the transmission belt during the rotation process. The opening and closing slider moves and slides on the active screw or the transmission screw through the transmission slider, and when the two sets of opening and closing sliders move away from each other, the gap between the fixed plug plate and the connecting plate is opened, at which time the dust can fall into the dust collecting box from the gap, and the dust in the dust collecting box can be discharged from the dust outlet.

[0022] 3. Compared with the prior art, the desulfurization, denitrification, dust removal and cleaning equipment for industrial waste gas for air pollution prevention and control dries and adsorbs the waste gas after desulfurization and denitrification, so that the moisture in the waste gas and the possible mixed treatment liquid waste liquid can be completely removed, ensuring the cleanliness of the exhaust air and reducing the pollution of the waste gas. The waste gas after absorbing mist and water vapor is passed from the drying pipe to the activated carbon adsorption box, and when the waste gas passes through the drying pipe, the heating sleeve heats and dries the gas in the drying pipe, thereby further removing the moisture in the gas. The gas after further removing the moisture enters the activated carbon adsorption box, and the activated carbon in the activated carbon adsorption box further absorbs the moisture and impurities in the flue gas, and the flue gas passes through multiple sets of ventilation connecting plates and activated carbon for adsorption, so that the gas discharged from the exhaust port of the exhaust pipe is clean.

[0046] The working process of the present application is as follows: first, the waste gas generated by industrial production enters the dust removal device 1 through the air intake pipe 12 for dust removal, and the dust in the waste gas is adsorbed by the dust collecting rod 17, so that the dust in the waste gas is separated from the waste gas, and the dust collecting rod 17 is connected to the dust collecting rod fixing plate 151 through the electrostatic connecting rod 172, and the electrostatic generator 16 acts on the electrostatic connecting rod 172 through the connecting wire 173, so that the electrostatic connecting rod 172 is charged with static electricity, and the static electricity on the electrostatic connecting rod 172 acts on the dust collecting bag 171, so that the dust in the waste gas can be captured and adsorbed by the dust collecting bag 171, thereby separating the dust from the waste gas;

[0047] When the dust bag 171 captures too much dust, the electrostatic generator 16 and the electrostatic connecting rod 172 connected thereto are powered off, so that the dust captured by the dust bag 171 falls off the dust bag 171, and ventilation can be used to assist the dust on the dust bag 171 to fall off.

[0048] The exhaust gas treated by the dust removal device 1 is sent into the smoke inlet connecting tube 3 through the smoke delivery pipe 13. When the exhaust gas enters the smoke inlet connecting tube 3, it first passes through the swirl plate 51. When passing through the swirl plate 51, the exhaust gas spirally rises from the swirl plate 51, so that the exhaust gas rises evenly. The solution in the treatment liquid tank 7 is transported to the spray pipe 56 through the spraying liquid inlet pipe 74, and the solution in the treatment liquid tank 7 is driven by the stirring motor 711 in the stirring motor box 71 to rotate and stir the stirring rod 73, so that the concentration of the solution in the treatment liquid tank 7 is always uniform, which is convenient for subsequent reaction work.

[0049] The solution after reacting with the exhaust gas falls into the recovery solution box 4, and the reacted solution in the recovery solution box 4 can be discharged and recovered through the recovery drain port 41, and the exhaust gas after absorbing mist and water vapor is passed through the drying pipe 52 to the activated carbon adsorption box 6, and when the exhaust gas passes through the drying pipe 52, the heating sleeve 53 heats and dries the gas in the drying pipe 52, thereby further removing moisture from the gas, and the gas after further removing moisture enters the activated carbon adsorption box 6, and the activated carbon 62 in the activated carbon adsorption box 6 further absorbs moisture and impurities in the flue gas, and the flue gas passes through multiple sets of ventilation connecting plates 63 and activated carbon 62 for adsorption, so that the gas discharged from the exhaust port 611 of the exhaust pipe 61 is clean.
