Description

Technical Field

With the changes in energy structure and the enhancement of environmental protection awareness, gas generator sets, as a clean and efficient way of power generation, have gradually attracted market attention. Gas generator sets will produce a lot of flue gas during operation, and these flue gases contain a lot of nitrogen oxides, which are also one of the main pollutants in the atmosphere. Therefore, it is necessary to purify the nitrogen oxides contained in the flue gas, otherwise the nitrogen oxides will enter the atmosphere and pollute the atmospheric environment.

[0003] A flue gas purification device is required for flue gas purification. The existing flue gas purification device generally achieves the purification purpose by spraying the flue gas. When the sprayed liquid comes into contact with the dust particles in the flue gas, the dust particles in the flue gas will adhere to it. Since the flue gas is in a flowing state during purification, relying solely on the spraying method cannot ensure that the flue gas and the spraying liquid can fully contact, so that part of the flue gas is discharged without being sprayed, thereby resulting in incomplete flue gas purification, making the effect of purifying the flue gas unsatisfactory, and reducing the working efficiency of the flue gas purification device.

After the roller rotates, it squeezes the hose, so that the flue gas in the spray box enters the purification box through the first gas pipe, the hose, and the second gas pipe, which speeds up the speed of the gas entering the purification box from the spray box and improves the working efficiency of the flue gas purification.

[0021] 4) When the second motor drives the connecting shaft to rotate, the second bevel gear on the connecting shaft rotates accordingly, the first bevel gear meshes with the second bevel gear to drive the second rotating shaft to rotate, and the fifth pulley coaxial with the first bevel gear rotates synchronously. The fifth pulley drives the fourth pulley to rotate through the third belt, thereby driving the stirring shaft to rotate. The stirring rod on the stirring shaft rotates accordingly to stir the lime water at the bottom of the spray box, preventing the lime water from settling at the bottom of the spray box, thereby ensuring the effect of the lime water on the flue gas.

[0022] 5) A scraper is installed under the multiple stirring rods at the bottom of the stirring shaft. The bottom of the scraper is in contact with the bottom inner wall of the spray box. When the lime water in the spray box is discharged, the scraper can drive the lime water to move, which can reduce the residual lime water inside the spray box and is conducive to the discharge of lime water.

[0023] 6) The exhaust pipe is spiral-shaped, which can further reduce the flow rate of the flue gas, facilitate sufficient spraying of the flue gas, and improve the purification effect of the flue gas.

[0024] 7) The first spray plate is in the shape of a ring, and the second spray plate is in the shape of a disc. The flue gas passes through the obstruction of the second spray plate and moves around the second spray plate before moving upward. The flue gas moving upward will be sprayed for the second time by the spray head on the first spray plate, thereby improving the effect of flue gas purification.

[0025] 8) On both sides of the filter frame, a cavity is opened on the upper side wall of the air intake duct, and a sealing component is installed inside the cavity. The sealing component can prevent the smoke in the air intake duct from moving upward, ensuring that the smoke in the air intake duct can flow normally, which is beneficial to the purification of the smoke.

[0026] 9) A reinforcement rod is installed between the air intake pipe and the spray box, which improves the stability of the air intake pipe installation. BRIEF DESCRIPTION OF THE DRAWINGS
