Description
Technical field
The present invention relates to a kind of charing equipment, particularly a kind of continous way charring furnace that can in carbonization process, prevent the material caking.
Technical background
Biomass energy is a kind of good renewable energy source, is resources effective such as oil, coal are replenished.More common biomass materials such as agricultural crop straw etc. owing to utilize mode few, normally pile up in the fields and directly burn habitually in the past, not only waste, and contaminate environment.Along with the research and development of biomass energy, biomass material comprises that the wood chip in agricultural crop straw, forest farm etc. can pass through high temperature carbonization, thereby realizes multiple use.Traditional charing equipment generally is to allow biomass material be in carry out charing under the hot environment, adopt the cooking stove formula of sealing, a charging needs to seal coking chamber later on and carries out charing, after finishing, charing carries out discharging again, can't continuous firing, and in discharging with again in the fill process, calorific loss is bigger, and is less economical.
And the present charring furnace that continous way work is also arranged, CN102363729A patent as Patent Office of the People's Republic of China's bulletin on February 29th, 2012, name is called stalk coke oven, this device comprises coking chamber, the burner of heat is provided for coking chamber, be provided with the charing auger in the described coking chamber, the charing auger has an opening for feed and a discharge port, and the auger wall of charing auger is provided with some airways that inflammable gas exported to the coking chamber outside.Realize continuous input and output material work in this device use, and in carbonization process, can effectively inflammable gas be derived and utilize to have very high energy utilization efficiency.But there is following defective in this device use: 1, charing auger barrel is tubular, make and be subjected to the barrel restriction with the spiral motion of helical feed sheet in the biomass material carbonization process, biomass material lacks relative movement, when barrel transmits heat biomass material is carried out from outside to inside carbonization process, rotate synchronously with the helical feed sheet material back of luming easily after the charing, cause the charing in the auger after material can't normally carry.2, opening for feed and discharge port are arranged on the auger, pass in the gap of the flue gas of cracking by biomass material in the part carbonization process, overflow from opening for feed and discharge port, pollute and energy dissipation.
Summary of the invention
The objective of the invention is to solve in the existing auger continuously carbonizing equipment after the charing material easily caking rotate with auger, cause the conveying blocking problem, a kind of continous way charring furnace of anti-caking is provided.
Another object of the present invention is to solve the problem that flue gas in the existing auger continuously carbonizing equipment overflows from opening for feed and discharge port easily, and a kind of continous way charring furnace that prevents that flue gas from overflowing is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of anti-caking continous way charring furnace, comprise that coking chamber, coking chamber one side are provided with the burner that the charing heat is provided, described coking chamber is separated to form mutual disconnected hot blast chamber and feeding channel by dividing plate, the hot blast chamber is looped around the feeding channel outside, burner is communicated with the hot blast chamber, described feeding channel is the reciprocating type structure for conveying of the multilayer of stacked on top of one another, the end of each layer feeding channel is provided with the vertical passageway that is communicated with the lower floor feeding channel, is arranged side by side a plurality of helical feed sheets on every layer of feeding channel.The indoor hot blast by burner of hot blast provides the charing heat, the transfer passage of biomass material in coking chamber during feeding channel, feeding channel all adopts a plurality of helical feed sheets to carry side by side for every layer, make every layer of transfer passage be the cylinder section that flat cross section replaces traditional auger, improve the restriction of barrel to mass transport of knowing clearly, make biomass material when charing is lumpd, can not be subjected to the barrel restriction and only rotate synchronously with single helical feed sheet, and cause conveying not smooth.This structure at biomass material when charing is lumpd, can throw away, enter adjacent spiral conveying blade with the turning direction tangent line of a spiral conveying blade and carry scope, and the spiral conveying blade on the limit is after piling up too high biomass material, spiral conveying blade in the middle part of random device natural vibration, biomass material can be scattered is back naturally carried scope, formation moves in circles, and has avoided biomass material charing caking back to rotate synchronously with spiral conveying blade.Biomass material is reciprocal transportation in the feeding channel of stacked on top of one another, and the feeding channel throughput direction of neighbouring layer is opposite, has increased the distance that charing is carried.
