Description
Technical field
The utility model relates to a kind of gas cooled retracting device, particularly relates to the receiving apparatus that cools back of pyrolysis gas after a kind of dry distillation of wood.
Background technology
The thermal decomposition of wood be timber at secluding air or pass under the condition of a small amount of air, add the process of thermal decomposition.The thermal decomposition of wood comprises the dry distillation of wood (referring generally to hard wood distillation), makes charcoal, soft wood distillation, the destructive distillation of birch skin and the Activated Carbon Production take wood chip, charcoal as raw material.The dry distillation of wood is to be that raw material adds thermal decomposition in retort with branch, the tip of a branch and firewood forests, produces gaseous product, through condensation separation, obtains pyrolkigneous liquid, wood tar, wood gas etc., and the solid product that remains in the retort is charcoal.Wood tar and pyrolkigneous liquid are further processed, and also can get a lot of chemical products.(selecting and edit from " Chinese Resources science encyclopedia ")
The organic compound that wood tar is a kind of hydrocarbon-containifirst, acids, phenols is higher contains phenolic compound and reaches 10-50% in the wood tar.Can obtain creasote, anti-poly-agent, floatation frother after the processing, the products such as wood pitch.Also can be used for the departments such as medicine, synthetic rubber and metallurgy
The steam gas mixture that generates when crude pyroligneous acid is the dry distillation of wood reclaims the liquid product general name that obtains through condensing cooling, and its productive rate accounts for the 45-50% of ovendriedwood weight.Owing to all contain some moisture in the raw material timber, so actual yield is higher.Rare pyrolkigneous liquid can be directly used in soil disinfection.Can make the products such as acetic acid, acetate or acetate, methyl alcohol and other solvents after the processing.Be used for weaving, leather, food, organic synthesis and other industry.
The incoagulable gas that generates during the dry distillation of wood is called wood gas, and its productive rate accounts for the 16-18% of over dry raw material timber weight.The composition of wood gas is subjected to the impact of destructive distillation final temperature.Usually contain 40-50%CO
2, 25-35%CO, 15-23%CH
4, 1-5%C

4, 0.5-2.5%H
2Along with the rising of destructive distillation final temperature, CO in the wood gas
2And the content of CO reduces CH

Thermal decomposition of wood product can extensively be used in the aspects such as chemical fibre, synthetic rubber, spices, food processing, metallurgy, dyestuff, medicine, ore dressing, anticorrosion, national defence and environmental protection.
Usually the separation method of mist mainly contains cryogenic rectification method (abbreviation Deep Cooling Method), pressure swing adsorption method (also claiming the PSA method) and macromolecule embrane method.The former claims low temperature process, and both claim non-low temperature process afterwards.These methods not only technological requirement are high, and energy resource consumption is large, are fit to large-scale industrial production, reclaim inapplicable for dry distillation of wood pyrolysis gas.
The utility model content
The purpose of this utility model just provides that a kind of energy resource consumption is little, the pyrolysis gas of safe and simple cool back receiving apparatus.
The purpose of this utility model is to realize by such technical scheme: a kind of pyrolysis gas cool back receiving apparatus, it is characterized in that: comprise that the top is provided with the closed container of air inlet and gas outlet, described closed container upper end is provided with water inlet and delivery port, in described closed container, be provided with condenser coil I and condenser coil II, link to each other by the collector pipe I between described water inlet and the described condenser coil II, link to each other by the collector pipe II between described condenser coil II and the described condenser coil I, link to each other by the collector pipe III between described condenser coil I and the described delivery port, be provided with the separation chamber with porous plate below described condenser coil II and the described condenser coil I, bottom, described separation chamber is provided with oil-out and liquid outlet.
In order to guarantee that the pyrolysis gas condensation effect is good, described condenser coil I and described condenser coil II are provided with more than one group.
In order to guarantee that the abundant condensation of wood tar and pyrolkigneous liquid goes out, different according to wood tar and pyrolkigneous liquid boiling point, the group number that the group number that described condenser coil II arranges arranges greater than described condenser coil I.
In order to isolate respectively wood tar and pyrolkigneous liquid in described separation chamber, described oil-out is lower than liquid outlet.
Owing to adopted technique scheme, the utlity model has following advantage:
(1) the utility model is the different boiling of utilizing wood tar and pyrolkigneous liquid, with condenser coil I and two sections condenser coils of condenser coil II the direct condensation of pyrolysis gas is reclaimed respectively, obtains respectively wood tar and pyrolkigneous liquid through precipitate and separate, and not solidifying wood gas is discharged; Three groups of collector pipes that arrange have been accelerated the flow velocity of cooling water, have improved the condensation efficiency to pyrolysis gas; Cooling water is recycling after heat exchange.
