Benefits of technology

The present technology described involves making use of recycled acidified waters from various industries such as manufacturing or processing plants that produce harmful chemicals during their operation. These liquids contain large amounts of impurity elements like iron (Fe) and chromium(Cr). To save money on disposing these wastes properly, they have been treated beforehand instead of discarding them afterward. This helps protect our natural resources better while reducing environmental concerns associated therewith. Additionally, some plasma-based processes require high levels of oxygen gas purification due to its potential health hazards caused by excessive exposure to airborne particles containing Fe3+or Cr6+) generated through combustion processors. Overall, this new method provides an efficient way to treat industrial effluents effectively without generating unwanted substances.

Problems solved by technology

This patented technical problem addressed by this patents relates to reducing emissions from combustion sources that contain SO2. These gases can be damaging for both human bodies and wildlife if they are released into atmosphere without being treated properly or with proper treating techniques.

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] A double-alkali flue gas desulfurization equipment, such as Figure 2-3 As shown, it includes a desulfurization tower, a regeneration tank and a filter press. The regeneration tank is divided into four treatment tanks in sequence by three partitions. From left to right, they are the first treatment pool, the second treatment pool, and the third treatment pool. And the 4th treatment pool, filter screen 14 is set on the first partition 11 and the 3rd partition 13; Preferably, filter screen 14 is arranged on the top of the first partition 11 and the 3rd plate 13, to guarantee that filter screen do

Abstract

The invention discloses a double-alkali flue gas desulfurizing method, and relates to the field of waste gas treatment. The double-alkali flue gas desulfurizing method comprises the following steps: S1, producing an absorbent; S2, absorbing SO2in a desulfurization tower; S3, regenerating the absorbent in a regeneration tank; S4, supplementing alkali water; S5, treating a sulfurized product. Through use of waste alkali water as a regenerant, the desulfurization cost is saved and the environment is protected; a desulfurization product is calcium sulfite, which has a great effect in life.
