Description

Charring furnace

Technical field

The utility model is a kind of charring furnace, belongs to carbon production apparatus field.

Background technology

Charring furnace be for by biological material if wood chip, stalk etc. are under high temperature, anoxia condition, form the device of porous carbon structure.In carbonization process, produce a large amount of coal gas in charring furnace, these coal gas do not make full use of, and cause the waste of the energy.CN102032553A " equipment of a kind of continuous rotary biomass pyrolytic charing and boiler heat supplying integration " discloses one and utilizes biomass pyrolytic to carbonize generation wood gas, the equipment of high temperature energy is provided by the high-temperature flue gas form biomass pyrolysis produced after burning, although wood gas is recycled by this equipment, but there is following deficiency in this equipment: coal gas easily condenses into wood tar oil, cause line clogging, contaminated equipment and environment.

Utility model content

For the deficiency that prior art exists, the utility model object is to provide a kind of charring furnace, and the coal gas produced in carbonization process is fully recycled, and the tar blocking pipe that coal gas can be avoided to produce.

To achieve these goals, the utility model realizes by the following technical solutions: a kind of charring furnace, comprise body of heater, coking chamber and coke discharging room is divided in described body of heater, hot gas in described coking chamber is communicated to coke discharging indoor by vapor pipe, described coke discharging indoor are provided with the solidifying burnt plate that two row stagger up and down, the solidifying burnt plate of two row lays respectively at the both sides of the vertical centerplane of coke discharging room, each solidifying burnt plate is downward-sloping to vertical centerplane by the inwall of coke discharging room, the bottom of described coke discharging room is coke discharging mouth, described coke discharging room sidewall is provided with pneumatic outlet near bottom position, described pneumatic outlet is communicated with the supervisor be positioned at above body of heater.

Further, the pneumatic outlet of described coke discharging room is communicated with coking chamber by product heat cal rod.

Further, described vapor pipe and product heat cal rod overcoat have water-cooled tube.

Further, described coking chamber comprises inner barrel and outer cylinder body, and the combustion chamber for closing between described inner barrel and outer cylinder body, the inside of described inner barrel is material placement space.

The beneficial effects of the utility model: a kind of charring furnace of the present utility model, comprise body of heater, coking chamber and coke discharging room is divided in described body of heater, hot gas in described coking chamber is communicated to coke discharging indoor by vapor pipe, described coke discharging indoor are provided with the solidifying burnt plate that two row stagger up and down, the solidifying burnt plate of two row lays respectively at the both sides of the vertical centerplane of coke discharging room, each solidifying burnt plate is downward-sloping to vertical centerplane by the inwall of coke discharging room, the bottom of described coke discharging room is coke discharging mouth, described coke discharging room sidewall is provided with pneumatic outlet near bottom position, described pneumatic outlet is communicated with the supervisor be positioned at above body of heater.Because the hot gas in carbonization process is recycled by supervisor by the charring furnace of this structure, meanwhile, owing to being provided with coke discharging room, make the hot gas that produces in carbonizing before entering supervisor in coke discharging indoor just by coke discharging, supervisor can not tar and blocking.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of charring furnace of the utility model.

Embodiment

The technique means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.

Refer to figure, the utility model provides a kind of technical scheme: a kind of charring furnace, comprises body of heater 1, is divided into coking chamber 2 and coke discharging room 3 in described body of heater 1.Coking chamber 2 comprises inner barrel 21 and outer cylinder body 22, combustion chamber for closing between described inner barrel 21 and outer cylinder body 22, the inside of described inner barrel 21 is material placement space, the powder of biomass or bar are placed in inner barrel 21, the heat produced in combustion chamber enters in inner barrel 21, make material by high temperature carbonization, in carbonization process, produce heat smoke.Hot gas in coking chamber 2 is communicated in coke discharging room 3 by vapor pipe 4, the solidifying burnt plate 5 that two row stagger up and down is provided with in described coke discharging room 3, the solidifying burnt plate of two row lays respectively at the both sides of the vertical centerplane of coke discharging room, each solidifying burnt plate is downward-sloping to vertical centerplane by the inwall of coke discharging room, the bottom of described coke discharging room 4 is coke discharging mouth 31, described coke discharging room 4 sidewall is provided with pneumatic outlet 32 near bottom position, and described pneumatic outlet 32 is communicated with the supervisor 6 be positioned at above body of heater 1.Hot gas enters after in coke discharging room 3 and runs into solidifying burnt plate 5, objectionable impurities in hot gas condenses into tar after running into solidifying burnt plate 5, and discharge from coke discharging mouth 31, except upper comb 10 then upwards enters in supervisor 6 by defocused hot gas, hot gas is delivered to other operations and is used by supervisor 6, because hot gas has first carried out coke discharging before entering supervisor 6, such hot gas can not produce tar to block supervisor 6 in supervisor 6.Solidifying burnt plate 5 staggered arrangement of two row makes, and hot gas is partially formed eddy current, contacts more abundant, solidifying burnt better effects if with solidifying burnt plate 5.In order to improve solidifying burnt efficiency, outside coke discharging room 3, being surrounded by water-cooled tube 9, in water-cooled tube 9, passing into water coolant, by water coolant, the temperature in coke discharging room 3 is reduced, avoid flue gas to form solid-state Jiao at high temperature in the indoor reaction of coke discharging.

In order to improve heat recuperation rate, threeway 7 is provided with outside the pneumatic outlet 32 of described coke discharging room 3, threeway is communicated with product heat cal rod 8 with pneumatic outlet 8, upper comb 10 respectively, product heat cal rod 8 is communicated with coking chamber 2, by product heat cal rod 8, the portion gas heat of pneumatic outlet 32 is carried out being recycled in coking chamber 2, improve temperature in coking chamber 2.In like manner, there is water-cooled tube 9 at vapor pipe 4 and product heat cal rod 8 also overcoat, reduce hot gas solidifying burnt probability in supervisor further, reduce and be responsible for blocked possibility.

More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model, to those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, the utility model can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.

In addition, be to be understood that, although this specification sheets is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of specification sheets is only for clarity sake, those skilled in the art should by specification sheets integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
