Abstract
The utility model relates to an incinerator of medical refuse, which essentially consists of a combustion chamber, an ash chamber, an air preheater and a chimney, wherein a preheating ventilation duct, a second air duct and a third air duct are equipped at the external wall in the combustion chamber above which an airflow baffle is equipped. The first air, the second air and the third air after a preheating can be blown into the combustion chamber from the different direction. In case of incinerating the refuse of lower heat value, one burner is sufficient for a combustion promotion; in case of incinerating the refuse of high heat value, the burner for combustion promotion is excessive. In case of incinerating the medical refuse, no smoke and odor generates, which saves the fuel consumption and lowers the operation cost.
Description
The utility model relates to a kind of incinerator for medical garbage, and it is mainly used in the medical waste of burning disposal hospital.
Chinese patent ZL93220173.3 has described existing incinerator, and such incinerator mainly is made up of first combustion chamber, second combustion chamber, grey chamber, air preheater, chimney.Though this class incinerator has solved the problem of waste incineration, need two burners combustion-supporting during operation, fuel consumption is big, the operating cost height.
In order to overcome the deficiency of above-mentioned incinerator, the purpose of this utility model is to provide a kind of novel incinerator, this incinerator is only established a combustion chamber, when burning waste of low heating value, only need a burner combustion-supporting, when burning higher calorific value rubbish, do not need burner combustion-supporting, thereby reach fuel savings, reduce the purpose of operating cost.
The purpose of this utility model is achieved in that the utility model mainly is made up of combustion chamber, grey chamber, air preheater, chimney etc., it is characterized in that, a plurality of pre-warm-air pipes is set in the inwall of combustion chamber, a plurality of secondary air channels and a plurality of tertiary-air pipe are set; Pre-warm-air pipe top communicates with air preheater, and the bottom communicates with grey chamber; Secondary air channel with communicate with grey chamber, tertiary-air pipe communicates with air preheater; Have a plurality of secondary air holes and a plurality of tertiary airs hole on the inwall of combustion chamber, from the beneath combustion chamber of sending into, secondary wind wall scattering in the combustion chamber enters the combustion chamber by grey chamber for wind, and tertiary air is sent into from combustion chamber tangent to periphery direction, forms swirling eddy.On top, combustion chamber blast fence is set, blast fence is a hollow structure, communicates with air preheater, has a plurality of scattered porosities at blast fence circumferencial direction and bottom.
The utility model is by burner hearth the further preheating of combustion air; not only protect burner hearth but also improved combustion air temperature; the high temperature combustion air enters the combustion chamber with different angles from different directions; make rubbish fully burning under the high temperature air effect; reduce and pollute; reduce the generation of dioxin, and fuel savings.
Below in conjunction with Figure of description the utility model is further described.
Accompanying drawing is a structure chart of the present utility model.
Illustrated by the structure of accompanying drawing incinerator for medical garbage.Incinerator mainly is made up of combustion chamber 3, grey chamber 8, air preheater 2, chimney 1 etc.A plurality of pre-warm-air pipes 13 are set in the inwall of combustion chamber 3, and pre-warm-air pipe 13 tops communicate with air preheater 2, and the bottom communicates with grey chamber 8; Also be provided with a plurality of secondary air channels 11 and tertiary-air pipe 4 in the inwall of combustion chamber 3, secondary air channel 11 communicates with grey chamber 8, has a plurality of secondary air holes 10 above; Tertiary-air pipe 4 communicates with air preheater 2, has a plurality of tertiary airs hole 5 above, the tertiary air hole along the combustion chamber 3 inwall tangent to periphery arrange; 3 tops are provided with blast fence 15 in the combustion chamber, and blast fence is a hollow structure, and top communicates with air preheater 2, have a plurality of scattered porosities 14 with circumferencial direction below blast fence 15; 3 middle parts, combustion chamber are provided with charge door 12, and a fire grate 7 is adorned in the bottom, and burner 6 is equipped with in the combustion chamber; Ash chamber 8 is provided with ash hole 9, and an air inlet 16 is left on air preheater 2 tops.
Effect to incinerator for medical garbage describes below.Start burner when burning away the refuse, heat up in the combustion chamber, when being raised to 300 ℃, furnace temperature drops into rubbish, and by the air inlet air feed, rubbish fire burns, the combustion air that is infeeded by air inlet is through the air preheater preheating, and by the further preheating of pre-warm-air pipe, secondary air channel, tertiary-air pipe that is arranged on the combustion chamber inwall, wind of high temperature enters the combustion chamber by the bottom, combustion chamber, high temperature secondary wind enters the combustion chamber from the secondary air hole scattering, the high temperature tertiary air sprays into the combustion chamber along combustion chamber tangent to periphery direction, forms swirling eddy; Under the immixture of wind of high temperature, secondary wind, tertiary air, rubbish fully burns, and the high-temperature flue gas no color or smell that burn to produce enters atmosphere through chimney, burns the ashes that the produce ash entrance chamber that falls.
Incinerator for medical garbage burn water content big, when calorific value is lower than 3000 kilocalories/kilogram waste of low heating value, it is combustion-supporting to start burner; Incinerating combustion value is higher than 3000 kilocalories/kilogram rubbish, and is must burner not combustion-supporting.Because the heat that produces when burning is recycled fully, under most of situation, burning away the refuse does not need burner combustion-supporting.Burn effectively, the flue gas odorless does not have flue dust, fuel savings.Since only adopt a burner, so it is cost is low, easy and simple to handle.
