Description
Technical field
The utility model relates to a kind of biological treatment device of high temperature foul waste gas, belongs to environmental technology field.
Technical background
Odor pollution is as one of the world's seven overall situation public hazards, and stench is complained increasing.The foul waste gas pollution prevention technique mainly contains absorption process, absorption method, catalytic oxidation, photocatalytic method, corona method, ozone method, plasma method and microbial method etc.The biological deodorizing method is compared with physical-chemical process, has that operating cost is low, simple to operate, treatment effect is good and characteristics such as non-secondary pollution, becomes the main stream approach of deodorization research in recent years.From the early 1980s, biological method purification waste gas obtains very big development in Germany, Japan and Holland, and becomes one of the hot research field, forward position in world industry waste gas purification field gradually.Up to the present; Industries such as existing all kinds of microbial deodorant devices and equipment have been successfully applied to metallurgy, oil, chemical industry, light industry in states such as moral, day, lotuses, butcher, sewage disposal; The biological purification plant that puts into operation has exceeded thousand covers; Equipment and device development be commercialization situation, and effect are good.Domesticly start late in this respect, just begin the research that experimentizes of biochemical process purifying low-concentration waste gas up to the nineties.And there is bioanalysis to handle research reports such as containing ammonia foul smell, hydrogen sulfide and methyl mercaptan mixing [, house refuse stench, multicomponent odorous gas, pharmaceutical factory's volatility mix waste gas, aquatic feeds foul waste gas.Domestic biotechnology has realized practical applications in exhaust-gas treatments such as reclaimed rubber factory, aquatic feeds foul waste gas, pharmaceutical factory's oxygen compatibility pool high concentration stench, oil refining sewerage factory evil and sewage plant bad smells.
The bio-trickling method is the later stage eighties 20th century deodorization technique just to occur, and it is little that it has pressure drop, is difficult for stopping up, and contaminant removal capacity is strong, is prone to regulate advantages such as control, and therefore developing the bio-trickling deodorization equipment has become at present the focus of research both at home and abroad.Be primarily aimed at the foul waste gas biological treatment under the normal temperature condition both at home and abroad, but less to high temperature foul waste gas biological treatment research with application.It is generally acknowledged that it is 30-40 ℃ that bioanalysis is handled the preference temperature of foul gas, hot environment can be killed deodorizing microorganism.To the biological treatment of high temperature foul gas, generally pass through first spraying cooling, this not only consumes a large amount of water, and produces a large amount of waste water, causes secondary pollution, increases spray wastewater treatment expense simultaneously.In used heat oven dry mud, the sludge incineration process of cement kiln, many industry such as aquatic feeds production, petrochemical industry refining etc. produce high-temperature gas.Press for the new type high temperature biological deodorization device that can address the above problem.
Summary of the invention
The purpose of the utility model provides a kind of biological treatment device of high temperature foul waste gas.The microorganism that overcomes traditional biological deodorizing equipment can not be born the shortcoming of hot environment, deodorizing effect difference, provides that a kind of process equipment is simple, the biological treatment device of convenient for maintenance management, the investment operating cost is low and odor removal efficient is high high temperature foul waste gas.
High temperature foul waste gas biological treatment device drips filter bed district, classified spraying device, demister and circulation fluid storage tank by ceramics filling Biotrickling filter district, biological activated carbon and connects to form successively.This device is reverse-flow or cross-current type bio-trickling device, steel construction or xoncrete structure.Drip the combination of filter bed district by first ceramics filling Biotrickling filter district artifact active carbon.Adopt the deodorizing microecosystem of the microorganism species structure of special efficacy degraded foul gas.Every layer filter bed all is provided with spray equipment in the high temperature foul waste gas biological treatment device, and spray equipment adopts beam type gas ejection-type support plate and the supporting use of liquid re-distributor, can solve the shower nozzle blockage problem.This microorganism fungus kind can adapt to 10～68 ℃ of wider temperature range, and tolerance low temperature and high temperature have better deodoriging properties.Used filler (carrier) is haydite, pottery piece, mixed fillers etc. in the bio-trickling device, and the filler layering is loaded.Each filler unit is established a gas flow guiding orifice plate and one group of distributing slot, and waste gas and shower water are evenly distributed.
In the biological cycle liquid storage tank aeration tube is set, the pH probe is set to regulate the appropriate pH value of circulation fluid automatically through adding acid or alkali.The mist device install is removed at the bio-trickling device top, it be with woven wire or synthetic fibers silk screen as except that the mist element, clamping is between two screens and constitute.
The utility model compared with prior art has the following advantages
1. equipment is simple, and main equipment is a bio-filtration deodorization device only.
2. have anti-shock loading property preferably, stable, can adapt to the requirement that noncontinuity is produced.
3. the microecosystem that makes up of special efficacy microorganism fungus kind, this system can adapt to 10～68 ℃ of wider temperature range, and tolerance low temperature and high temperature have better removal performance.
4. be suitable for the high temperature foul waste gas processing that the production phase produces, like mud oven dry, sludge incineration, aquatic feeds etc.
5. every layer filter bed all is provided with spray equipment.
