Benefits of technology
This technology involves collecting cleanseery effluents that have been treated by treaters for producing energy or other useful products such as fertilizers through evaporation techniques. By adding this process with pure water it can remove harmful gases like nitrogen oxide emissions while also making them more valuable than traditional methods.
Problems solved by technology
This patented technical problem addressed by this patents relates to improving the efficiency and control over treating harmful or offensive compounds from industrial wastes such as petrolgetics that can cause environmental concerns due to their volatile nature. Current techniques involve expensive physical separation steps like distillations, solvent extractions, adsorbents, etc., while also being limited in terms of specificity towards particular classes of molecules. Therefore there needs an improved way to effectively remove these contaminating gases without causing negative effects on workers' wellbeings.

The invention discloses a wastewater purification spraying device for petrochemical wastewater deodorization and a purification method of the wastewater purification spraying device. The purification method comprises the following steps: (1) firstly introducing wastewater exhaust gas from a first wastewater treatment plant and a second wastewater treatment plant into a buffer tank, then stabilizing gas flow and carrying out gas-liquid separation, and returning wastewater into the second wastewater treatment plant by a wastewater return pipe; (2) conveying purified water from the second wastewater treatment plant to a spraying head in an absorption tower by a water pump through a purified water pipe; and (3) enabling exhaust gas in the buffer tank to enter the absorption tower just below the spraying head through a gas inlet pipe, spraying the exhaust gas with purified water, discharging the purified exhaust gas from a gas collecting hood into an exhaust funnel by an induced draft fan through a gas outlet pipe, and returning the purified water which absorbs contaminants to the second wastewater treatment plant through the wastewater return pipe; according to the wastewater purification spraying device and the purification method disclosed by the invention, a wastewater purification spraying and absorption method is adopted, the purified water in the wastewater treatment plants is used as an absorbent to absorb the exhaust gas from a wastewater pool, and the exhaust gas is discharged from the top of the absorption tower. The wastewater purification spraying device and the purification method disclosed by the invention have the advantages of good treatment effect, economy, practicability, safety, reliability, low carbon and environmental protection.
