Description

Biological mud fume purifier of fume

Technical field

The utility model relates to a kind of kitchen oil fume purifying device, particularly relates to a kind of biological mud fume purifier of fume.

Background technology

Oil smoke is a kind of gaseous contaminant that people produce in the cooking food process, is edible oil and the food volatile matter at high temperature and the mixture of condensate aerosol and aqueous vapor, indoor dusty gas thereof.Compare with industrial smoke, oil content content height in the oil flue waste gas, viscosity is big, also has peculiar smell.On form, contain liquid, solid, gas three-phase pollutant simultaneously.Its chemical composition mainly is an organic matter, and kind is more, and is water-soluble relatively poor.

At present, the main industrial ventilation cleaner that adopts is handled oil smoke on the market, main type has mechanical type, filtering type, electrostatic, wet type, combined type etc., and low, the instant effect of these equipment development costs has been obtained certain effect aspect the pollution of oil smoke aerosol in control food and drink oil smoke.But because the greasy dirt viscosity that is captured down is big, strong adhesion, cause the resistance of separation equipment to increase, filtrate can not clean and utilize, isolation of purified equipment stops up, cause the action time of equipment continuous effective short, safeguard cleaning and running expense height, be easy to a difficult problem such as secondary pollution, and these equipment are generally not good to escaping gas treatment effect in the oil smoke; Abroad based on the physico-chemical process of thermal oxide burning method and catalytic purification method owing to being difficult to reduce cost significantly and safety issue restricts it and applies.There is following problem in existing specifically fume treating device: the effective storage life of (1) cleaning equipment is short.Most every month or need clean once half a year, especially outstanding for electrostatic separation equipment and this situation of filter plant.(2) some cleaning equipment complex structures efficiently, Operation and maintenance are had relatively high expectations, as electrostatic precipitation, isolated by filtration, wet scrubbing or the like.(3) most of cooking fume control equipments are only paid attention to the removal of oil smoke droplet, and are that the removal of peculiar smell is not included.And the resident is very big to the penetrating odor suggestion of the outer mist extractor of the catering trade at present.(4) efficient cleaning equipment cost and operating cost are higher, equipment cost mainly is meant apparatus body cost and material cost (the disposable filtrate used as filter plant), and operating cost comprises maintenance cost, cleaning expense etc. (cleaning oil pollution and the maintenance that separate with isolated by filtration and Wen as electrostatic separation).(5) research of home-use cooking fume cleaner seldom mainly utilizes the mechanical type fume exhausting fan directly to efflux at present, though family kitchen oil smoke discharge amount is few, because its One's name is legion, drain time is concentrated, and the total emissions amount still can not be ignored.Therefore, the characteristics big according to oil smoke viscosity are used new waste gas pollution control and treatment theoretical principle, and it is a privileged direction that the special-purpose oil smoke of development of new is administered.

Summary of the invention

The purpose of this utility model is to provide a kind of practicality, outer cooking fume purifier easily, oil smoke gas is through the biological mud layer in the device, pollutant is adsorbed and microbial degradation by mud, realizes Oil-gas Separation and qualified discharge, solves the outer mist extractor problem that disturbs residents.

The utility model is achieved in that biological mud ditch mixes earth by stainless steel, plastics or reinforcing bar and makes, the jet-flow aeration pipe is evenly arranged in biological mud ditch bottom, places groove approximately to 2/3rds groove eminences [liquid level gauge demonstration] in the active bio mud of having inoculated superior microorganism; Air inlet pipe connects gas skirt and is fixed in groove and covers with the jet-flow aeration pipe and link to each other, and dehydrating tower is fixed on groove and covers by being connected and fixed device, and temperature controller links to each other by magnetic valve with water inlet pipe, and water inlet pipe covers by being bolted to groove, and bottom land has mud discharging mouth; Air-introduced machine is installed on poor covering, and links to each other with dehydrating tower by air entraining pipe; The sensor of temperature controller stretches in the biological mud.

Characteristics of the present utility model are biological mud ditch, it is different with the operation principle of existing fume purifier of fume, the former is the organic assembling of biological and materialization principle, the latter only is physical principle or the principles of chemistry and simple combination thereof, biological mud is the activated sludge of having inoculated superior microorganism, oil flue waste gas enters biological mud layer in the jet-flow aeration mode, pollutants such as oil content are at first separated from gas by effects such as activated sludge absorption, absorptions, play biochemical reaction with microorganism then and generate small-molecule substance (CO ₂, H ₂O etc.), some difficult degradation things form the excess sludge discharge with microbial metabolic products.Be provided with the jet-flow aeration pipe, mud discharging mouth, water inlet and attemperating unit etc. in the biological mud ditch.Temperature control system can set up temperature bound (20 ℃～35 ℃) on their own, and inflow links to each other with attemperating unit, temperature surpass the upper limit then automatically water inlet be lower than lower limit and then stop into water.

The beneficial effects of the utility model are, collection collection cigarette, processing are one with control system, and compact conformation takes up an area of less; The treatment effeciency height, the oil content clearance can reach 95%, and the peculiar smell clearance can reach 90%; Antijamming capability is strong; Excellent in cushion effect; Energy consumption is low, can utilize the heat energy auto-control reaction temperature of flue gas self; The cost performance height.Installation and Debugging convenience, security of operation, non-secondary pollution.
