Description

The animal used as test incinerator

Technical field

The utility model belongs to the environmental sanitation equipment technical field, is specifically related to a kind of at the incinerator that burns harmful substance, particularly animal used as test.

Background technology

One of processing mode of harmful substance was to adopt to burn during prior art was produced life, as to hospital waste, part house refuse etc.At present, the incinerator that has had multiple structure, the better structure that compares is to adopt vertical body of heater, generally on main chamber, be provided with secondary combustion chamber, generally without handling or handling the back through simple spray and just advance in the atmosphere by smoke stack emission, the incinerator of this class formation can satisfy the burning of common rubbish to flue gas after the burning substantially.But for some special harmful rubbish, as hospital waste, spoil, the corpse of animal used as test particularly, they may contain many infective virus, therefore sufficient combustion is wanted high, if burn incompletely, poisonous and harmful substance such as dioxin, furans etc. just can not complete oxidations, decomposition, discharging advances in the atmosphere to cause secondary pollution.And the vertical structure of existing incinerator tends to occur the flame-out phenomenon of second-time burning anoxic because furnace cavity is less, can not realize abundant burning.In addition, also contain a large amount of cigarette ash, odor pollutant and peculiar smell molecule in the flue gas that discharge spoil burning back, and the spray of prior art is handled the cigarette ash can only dispose wherein, then acts on minimumly for stink and peculiar smell, so the direct discharging of these stink peculiar smell also can bring environmental pollution.Can't address the above problem effectively just because of existing incinerator, also there is not at present special spoil incinerator, and for the processing that requires stricter medical experiment spoil, just having only of having adopts simple incinerator to handle, great majority still are the underground mode of imbedding that adopts, and its harm is well imagined.

Summary of the invention

The purpose of this utility model is the problem at the prior art existence, providing a kind of is primarily aimed in experimental animal carcass, also applicable to the animal used as test incinerator of general spoil, high harm rubbish etc., to solve the adequacy problem of combustion furnace burning, further solve removal problem to the harmful stink and the peculiar smell of gas fume after burning.

The technical solution of the utility model is as follows:

A kind of animal used as test incinerator, it has automatic feed mechanism, body of heater, spray column and smoke evacuation system.Automatic feed mechanism is over against the charging aperture of body of heater, described body of heater is horizontal body of heater, have at least two combustion chambers, first combustion chamber is a main chamber, its underpart is provided with fire grate, inherent top, each combustion chamber or top are provided with combustor, are separated by dividing plate between each combustion chamber, and communicate on dividing plate top; The smoke outlet flue of body of heater connects spray column, and the smokejack of spray column is picked out by top, connects a clarifier, and the smoke outlet flue of clarifier inserts smoke evacuation system.

Described animal used as test incinerator also is connected with preheater between the smoke outlet flue of body of heater and spray column, the cool air hose front end of preheater is connected with combustion fan, and its hot-air is carried go back to the combustion chamber again by delivery outlet.

The chamber design of one combustion chamber, back is a little more than last combustion chamber in the described body of heater.

Described clarifier is made of housing, the supporting network of its inner lamination layout and the filtering material that is arranged on every layer of supporting network, leave suitable gas channel between the filtering material, and the gas channel between two-layer staggers mutually.

In addition, described smoke evacuation system includes chimney and injection blower fan, and the injection blower fan is upwards inserted in the chimney by the chimney bottom.

This incinerator has guaranteed enough combustion spaces by Proper Design is become horizontal, and at least two combustion chambers such as main chamber are set, and combustor is from upper furnace or top igniting, and these all are enough to guarantee abundant combustion efficiency.The further setting by preheater, to the particular design of front and back combustion chamber height with in the design of smokejack brake application plate valve, all facilitation has been played in abundant burning.In addition, at stink in the flue gas and peculiar smell, this incinerator has also been set up the clarifier that flue gas is had filtration when spray column is set, by choosing the filtering material of corresponding deodorizing taste removal, just can remove stink and peculiar smell effectively.In order reduce polluting as much as possible, and to reduce the capital expenditure of smoke removal facility, to adopt the injection blower fan, the height of chimney can be reduced greatly guaranteeing to reach under the condition of discharge standard.

Therefore, the utility model has the advantages that to rubbish, animal particularly animal used as test can carry out enough burning fully, fully burn bacterium, the virus of going out wherein, prevent harm to environment; In addition, can effectively remove flue dust, stink and peculiar smell in the flue gas, effectively avoid bringing auxiliary air to pollute.

This incinerator detects through experiment, and the fume emission after the burning can reach discharging standards fully.
