Abstract
The utility model relates to a filling for fetid bio-treatment which comprises a reticular polyurethane foam plastic filling and a hard plastic ring filling. The filling of the utility model overcomes the shortcoming in the single use of the reticular polyurethane foam plastic filling that the filling is easy to be rammed, the gas circulation is short, the fixed microorganisms are not easy to be replaced and the mid of the filling is easy to have the anaerobic zone; as well as the shortcoming in the single use of hard plastic ring filling that the filling is smaller than the surface area, the porosity is low and the membrane formation is not easy. The utility model makes full use of the respective advantages of the two types of fillings and reaches a optimistic processing effect in the fetid process.
Description
Technical field
The utility model is applied in the biological deodorizing tower, as the stench biological treatment filler.
Background technology
Filler is the important component part in the biological deodorizing system, and some characteristics of further investigation filler are developed some new packings, and meaning is very great for bad smell biological is handled.At present, filler commonly used mainly contains polypropylene pellets from natural cobble, coarse crushing stone, charcoal to the haydite of manually firing, pottery and synthetic, plastics, stainless steel, APC particulate, carbon fibre, sponge etc. in the biological deodorizing system.And the filler of these kinds in use exists such or such shortcoming, and for example specific surface area is little, and porosity is low, and easy to be filmed easily wears out, and vapour lock is big, and fixation of microbe is difficult for upgrading, the central easily generation anaerobic zone of filler etc.
Summary of the invention
The purpose of this utility model provides a kind of novel stench biological treatment filler, thereby increases packing specific area and wetting ability, improves the biological capacity of unit volume; Increase the porosity of filler, thereby increase adsorption, enlarge foul smell and biological contact surface foul smell; Increase the intensity of filler and alleviate quality, prevent compacting and the short stream of gas occurs.
For achieving the above object the utility model by the following technical solutions, this filler special is made up of two portions and is comprised reticulated polyurethane sponge plastics and rigid plastics ring packing.Make full use of the reticulated polyurethane sponge plastics as the advantage that specific surface area is big, porosity is high of filler and the big advantage of intensity height, hardness of rigid plastics ring packing.The reticulated polyurethane sponge plastics is the regular cube shape, and the size dimension scope is at 20mm-40mm; Rigid plastics ring packing size range is: diameter 30mm-60mm, long 30mm-60mm.Two kinds of fillers are to mix the mode in bulk biological deodorizing tower of packing into, and the blending ratio of reticulated polyurethane sponge plastics and rigid plastics ring packing is between 0.5-1 (weight ratio).In the biological deodorizing tower, the rigid plastics ring packing can be used as the skeleton of reticulated polyurethane sponge plastics filler, solved to increasing the easy compacting of filler that packing specific area uses reticulated polyurethane foam separately and caused, central authorities easily produce the problem of anaerobic zone.
The beneficial effects of the utility model are the advantages that made full use of above two kinds of fillers, have reached good deodorizing effect.The short stream of the easy compacting of filler that this utility model filler has occurred when having overcome independent use reticulated polyurethane sponge plastics as filler, gas, fixation of microbe are difficult for upgrading and filler central authorities easily produce shortcomings such as anaerobic zone, and the packing specific area that occurs when using the rigid plastics ring packing separately is little, porosity is low, shortcoming such as easy to be filmed not.

1. deodorizing towers among the figure, 2. reticulated polyurethane sponge plastics, 3. rigid plastics ring packing
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
The utility model is applied in the odor treatment system of sewage work, in the waste gas with H
2S is as main object, the H of investigating
2S concentration is 10-30ppmv, and the waste gas air quantity is 2000m
3/ h.Reticulated polyurethane sponge plastics and the Pall ring weight ratio of packing in the deodorizing tower 1 is 0.5-1: 1 mixed fillers.Reticulated polyurethane sponge plastics size 40mm * 40mm * 40mm; Pall ring diameter 50mm, long 50mm.The packing layer total height is 3-4m, and the specific surface area of filler 2 is 500-600m
2/ m
3, the specific surface area of filler 3 is 100-120m
2/ m
3Gas liquid under with adverse current in packing layer contacts and mass transfer process fully, reaches the purpose that removes foul gas, and the residence time of gas in filler is 3-6s.
