Description
Technical field
The utility model is related to a kind of pyrolysis installations, more particularly, to a kind of pyrolysis oven stove oxygen-enriching device.
Background technology
Pyrolysis oven has technologically advanced, process, (disposable charging and disposable slagging-off) easy to operate and safe, investment
Save, dust content low (burn agitation degree small), the advantages that operation and maintenance expense is low, service life is long.It is widely used in
Activated carbon manufactures and regeneration industry, charcoal (containing bamboo charcoal) manufacturing industry, the roasting processing industry of biomass alternative energy source product, metal
(nickel cobalt zinc/copper/iron/molybdenum/magnesium etc.) ore and kaolin roasting or calcination process industry, municipal sludge and industry are dirty
The pyrolysis of mud/house refuse and trade waste/waste and old circuit board-gasification resource utilization such as utilizes at the technical fields.
Existing pyrolysis oven generally uses normal air for combustion air and Secondary Air, since combustion air and Secondary Air introduce dress
It is invalid heat-carrying agent medium gas wherein up to the nitrogen of 79% volume ratio and be not involved in combustion process after setting system.This
Air blower is not only resulted in after some invalid gas componant introducing device systems and draft fan device is bulky, power is high, and
Air-introduced machine operation is caused because final smog discharge temperature necessarily is greater than dew point to avoid vapor condensation therein not
Steadily, excessive erosion (corrosion function of weak carbonic acid), the remaining sensible heat damage of this partial invalidity carrier gas occur for underground flue and chimney
Mistake also will be quite huge.In addition, this heat loss rate of partial invalidity carrier gas in waste-heat recovery device system is also considerable.
Utility model content
In order to overcome the shortcomings of the prior art, the utility model to provide a kind of heat that can effectively reduce gas consumption
Solve stove oxygen-enriching device.
A kind of pyrolysis oven oxygen-enriching device, including combustion-supporting gas chamber, gas gun, oxygen-enriched air import, the combustion-supporting gas chamber with
Combustion chamber import is connected, and the gas gun is embedded in combustion-supporting gas chamber, and the gas gun is connected with gas nozzle, institute
It states gas nozzle and is equipped with several equally distributed spray orifices；The oxygen-enriched air import is connected with oxygen-enriched air nozzle, described
Oxygen-enriched air nozzle includes ring flange, jet pipe and spout, and described jet pipe one end is connected with ring flange, the jet pipe other end and spout phase
Even, several flow distribution plates are equipped in the spout, the ring flange is connected with ring flange baffle.
Preferably, the combustion chamber entrance is equipped with spiral board.The rotation and injection that can speed up air-flow, provide high temperature
Gas guides airflow direction, protects gas gun, prevents gas backstreaming from entering combustion-supporting gas chamber, prevent the generation for " being tempered " phenomenon.
Preferably, the ring flange baffle is rounded, the ring flange baffle outer diameter is more than jet size.
Preferably, the flow distribution plate is embedded in spout.Being provided with of flow distribution plate is sprayed uniform conducive to oxygen-enriched air
Stablize, while increasing projected area.
The utility model is simple in structure, reasonable design, the gas nozzle of the utility model and setting for oxygen-enriched air nozzle
It sets, oxygen-enriched air can be made quickly, uniformly, accurately to spray into, so that fuel is sufficiently mixed with oxygen-enriched air, improve the burning of flame
Temperature and efficiency of combustion, while can effectively reduce gas consumption.
