The utility model discloses simple structure can effectively restrain the dioxin and synthesize, reduces environmental pollution's solid waste burns tail gas quench device.
Description
Affiliated technical field
The utility model belongs to Solid Waste Treatment device field, particularly a kind of solid waste burning tail gas chilling apparatus.
Background technology
Clinical waste comprises all kinds of solids such as clinical refuse, useless medicine, contain a large amount of bacteriums, pathogenic microorganism, parasite, also contain other harmful substance, have features such as space-pollution, acute infection and latency pollution, the harmfulness of its virus, germ be common house refuse tens, hundreds of even thousands of times.If deal with improperly,, also become the source of pestilence probably with the severe contamination that causes environment.Therefore the incineration disposal of clinical waste has caused the great attention of relevant department, and the incineration disposal scale of clinical waste is also increasing day by day.But because the tail gas treatment process technology and the equipment that match with incinerator do not pass a test, required time of tail gas temperature-fall period is longer, the result has caused the discharging of synthesizing in a large number, exceed standard of dioxin, has caused environmental pollution, has run counter to the innoxious principle of hazardous waste.
The utility model content
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, and it is synthetic effectively to suppress dioxin, reduces the solid waste burning tail gas chilling apparatus of environmental pollution.
Technical solution of the present utility model can realize according to following mode:
A kind of solid waste burning tail gas chilling apparatus is characterized in, contains: tower body; Top at described tower body is furnished with venturi; The lower passage of described venturi communicates with the bottom of tower body; Bottom at described tower body is furnished with exhanst gas outlet; Is furnished with shower nozzle A in the bottom of described venturi.
The utility model is furnished with standby shower nozzle B in the bottom of described tower body.
The utility model is simple in structure, and it is synthetic effectively to suppress dioxin, reduces environmental pollution.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model system construction drawing;
The specific embodiment
The utility model contains: tower body 1; Is furnished with venturi 2 on the top of described tower body 1; The lower passage of described venturi communicates with the bottom of tower body 1; Is furnished with exhanst gas outlet 3 in the bottom of described tower body 1; Is furnished with shower nozzle A4 in the bottom of described venturi.Is furnished with standby shower nozzle B5 in the bottom of described tower body 1.
Tail gas from incinerator enters from cooling tower top, carry out heat exchange with cooling medium-water, the tail gas cooling is reduced to rapidly below 200 ℃ when water is vaporized, has effectively avoided the synthesis temperature interval of dioxin, has therefore suppressed the synthetic of dioxin to a large extent.Establish a standby shower nozzle B5 in the venturi exit, when contingency occurring, lower the temperature with assurance tail gas.
The utility model is the medical wastes incineration system of disposal ability 1.5t/h, enter from the tail gas of incinerator 6 top from cooling tower, at the converging transition and the trunnion place of venturi and cooling medium-water carries out heat exchange and water is vaporized, exhaust temperature is controlled in 140-220 ℃ the scope by the self-con-tained unit regulating pondage simultaneously, guarantees that exhaust temperature is higher than dew point in synthetic suppressing dioxin.Its rate of temperature fall is 730 ℃/S, with rate of temperature fall be 270 ℃/S cooling tower comparatively speaking, the synthetic quantity of dioxin obviously reduces.Check experiment is carried out in sampling in the cooling tower exit, and when rate of temperature fall was 730 ℃/S as a result, the total amount of dioxin was 7.3ng-TEQ/Nm
3, when rate of temperature fall was 270 ℃/S, the total amount of dioxin was 15.1ng-TEQ/Nm
3, promptly the synthetic quantity of dioxin reduces 52%, and its effect is fairly obvious.
Claims (2)
1, a kind of solid waste burning tail gas chilling apparatus is characterized in that, contains: tower body (1); Is furnished with venturi (2) on the top of described tower body (1); The lower passage of described venturi communicates with the bottom of tower body (1); Is furnished with exhanst gas outlet (3) in the bottom of described tower body (1); Is furnished with shower nozzle A (4) in the bottom of described venturi.
2, according to the described solid waste burning tail gas of claim 1 chilling apparatus, it is characterized in that: be furnished with standby shower nozzle B (5) in the bottom of described tower body (1).
