Embodiment Construction

[0023] The specific implementation method of the present invention will be described below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 5 As shown, the present invention is completed by three sections, namely three sets of main equipment and its auxiliary equipment constitute a complete set of system equipment, to achieve the goal of solving the odor of smoke. They are dedusting cooling tower and its auxiliary equipment, micro-bubble washing tower and its auxiliary equipment, biological filtration tower and its auxiliary equipment. Among them, the dedusting and cooling tower 1 and the micro-bubble washing tower are used for cooling, dust removal and oil removal, laying the foundation for the deodorization of the biological filter tower 14, ensuring a suitable temperature, and avoiding the blocking of the biological filter tower 14 by dust and tar.

[0025] Dust removal and cooling tower 1: The dust removal and cooling tower 1 is provided with a p...

Abstract

The invention relates to a treatment technology and equipment for biological fermentation fungus residue drying flue gas stink. The method includes: a. subjecting the flue gas generated by fermentation fungus residue drying to washing cooling dedusting process to make the treated flue gas venting temperature not higher than 55DEG C and the dust removal amount of the flue gas not less than 90%; b. performing oil removal on the dedusted and cooled flue gas to let the tar and dust content of the flue gas both less than 2mg/Nm<3>; and c. removing peculiar smell from the oil removed flue gas by a biological filter tower. The equipment consists of a dedusting cooling tower, a microbubble washing tower and the biological filter tower connected in order. The technology and equipment provided by the invention solve the environmental pollution problem caused by the fungus residue drying flue gas stink, can thoroughly solve the flue gas stink, and the flue gas odor is lower than the emission standard and reaches the environmental protection emission standard, thus avoiding troubling residents.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a technology and equipment for controlling the odor of flue gas from drying biological fermentation slag. Background technique [0002] The bio-fermentation industry, including the industrial production of biopharmaceuticals such as antibiotics and amino acids, produces a large amount of biological residues, which are composed of mycelia and the precursors of biological fermentation substances, with a moisture content of more than 80%. These residues are usually dried in the industry The machine uses hot air or steam to remove the moisture in the fungus residue. The drying temperature is about 140°C, and some reach 600°C. The volatile organic compounds in the fungus residue are taken out with the hot air and have a strong pungent smell. Large-scale fermentation enterprises The output is large, the amount of fungus residue is large, and the amount of smoke is larg...
