Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1, 2 and 3, an environment-friendly waste gas purification absorption tower comprises a bottom plate 1, a tower body 5 is fixed on the upper side of the bottom plate 1, and an alkaline solution 19 is filled in the tower body 5. A fixed ring 14 is fixed inside the tower body 5, and a transfusion tube 15 is embedded inside the fixed ring 14. A plurality of spray columns 16 are arranged on the lower side of the fixing ring 14, each spray column 16 is communicated with the infusion tube 15, and a plurality of liquid spraying holes 18 are arranged outside the spray columns 16. The upside of bottom plate 1 still is fixed with a supporting bench 2, and hydraulic pump 3 is installed to the upside of a supporting bench 2, is connected with pipette 11, fluid-discharge tube 12 on the hydraulic pump 3 respectively, and the other end of pipette 11 links to each other with the downside of tower body 5. A first filter screen 10 is installed at a lower nozzle of the pipette 11 and adapted to prevent solid waste from entering the inside of the hydraulic pump 3. The level of the alkaline solution 19 is higher than the lower nozzle of the pipette 11. The other end of the liquid discharge pipe 12 is communicated with a liquid delivery pipe 15. The bottom of tower body 5 is connected with intake pipe 4, and waste gas passes through intake pipe 4 and gets into the inside of tower body 5. After waste gas enters the interior of the tower body 5 through the gas inlet pipe 4, acid gas in the waste gas reacts with alkaline solution 19, the acidic gas is adsorbed by the alkaline solution 19, the gas flow moves from bottom to top, the hydraulic pump 3 conveys the alkaline solution 19 at the bottom into the liquid conveying pipe 15 and disperses the alkaline solution into the spraying columns 16 through the liquid conveying pipe 15, the spraying columns 16 above the alkaline solution 19 spray the alkaline solution 19 through liquid spraying holes 18 arranged outside, and the fine alkaline solution 19 is sprayed through the liquid spraying holes 18 on the spraying columns 16, so that the gas can be fully contacted with the alkaline solution 19, and the unabsorbed acid gas is reabsorbed.
As shown in fig. 1, a second filter 17 is installed at the top exhaust port of the tower body 5 to prevent large particles from being discharged. The tower body 5 is internally provided with an adsorption layer 13 which is suitable for adsorbing harmful gas, and the adsorption layer 13 is internally provided with activated carbon particles. The outside of tower body 5 is fixed with vertical ladder frame 9, the easy access maintenance. The outside of tower body 5 is installed with barometer 8, can show the inside atmospheric pressure value of tower body 5, can send out the police dispatch newspaper when atmospheric pressure surpasss the default, prevents that inside pipeline from blockking up the back atmospheric pressure and rise. The bottom of the tower body 5 is connected with a waste liquid discharge pipe 6, and a valve 7 is arranged on the waste liquid discharge pipe 6. The alkalinity in the alkaline solution 19 is gradually weakened along with the increase of the gas flowing through the purification tower, more impurities are mixed in the solution, and the valve 7 can be opened to discharge the solution through the waste liquid discharge pipe 6 when the alkaline solution 19 needs to be replaced.
After waste gas enters the interior of the tower body 5 through the gas inlet pipe 4, acid gas in the waste gas reacts with alkaline solution 19, the acidic gas is adsorbed by the alkaline solution 19, the gas flow moves from bottom to top, the hydraulic pump 3 conveys the alkaline solution 19 at the bottom into the liquid conveying pipe 15 and disperses the alkaline solution into the spraying columns 16 through the liquid conveying pipe 15, the spraying columns 16 above the alkaline solution 19 spray the alkaline solution 19 through liquid spraying holes 18 arranged outside, and the fine alkaline solution 19 is sprayed through the liquid spraying holes 18 on the spraying columns 16, so that the gas can be fully contacted with the alkaline solution 19, and the unabsorbed acid gas is reabsorbed. The gas flow continues to rise, and the unadsorbed harmful gas is absorbed by the adsorption layer 13. Finally, the gas is discharged into an external connecting pipe through a top pipe orifice and is subjected to the next filtration. The environment-friendly waste gas purification absorption tower has good purification effect and full filtration.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
