Combined step coupling deodorization method and equipment thereof

Abstract

The invention discloses a combined step coupling deodorization method and equipment, the combined step coupling deodorization equipment comprises a washing tower, a biotrickling filter tower and a filter tower which are connected in sequence, the washing tower is internally provided with a spraying assembly, a macromolecule corrugated folded plate washing area macromolecule filler assembly and anoil removal filter; a plurality of trickling filter area macromolecule biological filler assemblies and circulating water assemblies are arranged in the biological trickling filter tower; a pluralityof filtering units are arranged in the filtering tower; the system further comprises a control system, and the control system comprises a detection module and a control module. Waste gas sequentiallypasses through the washing tower, the bio-trickling filter and the filtering tower, hydrogen sulfide in the waste gas at the final outlet is smaller than 0.1 mg / Nm < 3 >, and the odor concentration issmaller than 200. And automatic detection and automatic adjustment are carried out in each process through the control system, so that intelligent processing is realized.

Description

technical field [0001] The invention relates to the technical field of deodorization of domestic waste transfer stations and kitchen waste treatment plants, in particular to a combined cascade coupling deodorization method and equipment thereof. Background technique [0002] Mainly used in domestic waste transfer stations and kitchen waste treatment plants to produce high concentrations of hydrogen sulfide, methyl mercaptan, TRS (total reduced sulfur) gas, VOCs, particulate matter, animal and vegetable oils, etc., hydrogen sulfide 10-30mg / Nm 3 , the odor concentration is 20000-50000, the height of the exhaust pipe is limited (when there is a case where the exhaust pipe is lower than 15m or cannot be higher than the surrounding buildings according to the site conditions) and the emission standard is strict. At present, most deodorization reactors have low treatment efficiency, especially the lack of effective measures to remove animal and vegetable oils, and cannot adapt to t...

AI Technical Summary

Problems solved by technology

At present, most deodorization reactors have low treatment efficiency, especially the lack of effective measures to remove animal and vegetable oils, and cannot adapt to the current and future stricter exhaust gas emission standards, and the degree of self-control is low, the operation is low and the control is difficult. Only detect the concentration of hydrogen sulfide at the inlet and outlet and the pH value of the spray liquid
