The extrusion stress of friction butt joint between the inner wall of the tail end of the double-layer vacuum glass outer tube 5 and the outer wall of the lower end of the spherical glass inner tube 7 is from the stress generated by hooking connection between the inner tube fixing support 4 and the barb 3 on the inner wall of the double-layer vacuum glass outer tube 5; the extrusion stress of friction butt joint between the outer wall of the tail end of the spherical glass inner tube 7 and the inner wall of the inner tube interface 17 of the glass tee 10 and the inner wall of the bottle mouth of the collecting bottle 13 is from the gravity of the condensing tube.
The condensing pipe of the invention is characterized in that biomass thermal cracking gas (condensable and non-condensable) output by biomass thermal cracking equipment enters the condensing pipe from the air inlet 12 of the condensing pipe when in operation, wherein the condensable high-temperature biomass thermal cracking gas exchanges heat with cold air with lower temperature in a laboratory by taking glass as a medium in the process of passing through an elongated glass pipeline where the air inlet 12 is positioned, so that the heat and the temperature carried by the initial biomass thermal cracking gas are greatly reduced, and some high-boiling-point components in the biomass thermal cracking gas are firstly condensed on the inner wall of the glass pipeline where the air inlet 12 is positioned and fall into the collecting bottle 13 to collect partial high-boiling-point components in biological oil;
the biomass thermal cracking gas subjected to preliminary cooling and condensation enters a collecting bottle 13 to receive further air condensation and collection of a condensable part, so as to prevent explosion of the spherical glass inner tube 7 caused by overhigh biomass thermal cracking gas; the uncondensed biomass thermal cracking gas in the collecting bottle 13 is forced to enter the subsequent biomass thermal cracking gas, enters the spherical glass inner tube 7 from the tail end of the spherical glass inner tube 7 and moves upwards, and under the low-temperature environment condition provided by the condensing chamber 6, the biomass thermal cracking gas exchanges heat with the ice-water mixture in the condensing chamber 6 through the inner wall of the spherical glass inner tube 7, so that residual condensable components in the biomass thermal cracking gas are condensed on the inner wall of the spherical glass inner tube 7 and slide down to the collecting bottle 13, and the collection of low-boiling-point components in the biological oil is completed;
finally, non-condensable biomass pyrolysis gas is discharged from the exhaust port 1. Due to the continuous introduction of biomass thermal cracking gas, after absorbing heat of biomass thermal cracking gas in the spherical glass inner tube 7, ice blocks start to melt slowly by an ice water mixture (using an ice water mixture as an example) in the condensation chamber 6, when the ice blocks in the condensation chamber 6 are nearly completely melted, a proper amount of ice blocks need to be added into the condensation chamber 6 by unscrewing the screw cap 2, the screw cap 2 is screwed after the ice blocks are added, and then a valve in the water outlet 8 is opened to drain water so that a water line in the condensation chamber 6 is lowered to the lower end of the screw cap 2. According to the ablation condition of ice cubes in the condensation chamber 6 and the change of the water level line, corresponding measures are taken for the condensation pipe; the design of the double-layer vacuum glass outer tube 5 utilizes the principle of vacuum heat insulation to minimize the energy loss of the ice-water mixture in the condensation chamber 6, thereby improving the service time of once ice adding and enabling the condensation tube to work continuously and efficiently.
