As shown in Figure 2; Said boiler tube 2 comprises the stove tube 21 and the bell 22 that is positioned at stove tube 21 opening parts that is used to hold dry distillation medium; Be provided with the box body 23 that is used to hold catalyzer in the said stove tube 21; These box body 23 surfaces are covered with cellular ventilating pit, and said stove tube 21 bottoms are provided with the closed gas via-hole that is used to feed reaction gas, and said bell 22 is provided with destructive distillation gas and portals 26.Being provided with graphite gasket between said stove tube 21 and the bell 22 seals.The exit of said stove tube 21 is provided with cellular baffle plate 25, is used to stop material.Said stove tube 21 bottoms are provided with three thermowell 24.Said destructive distillation gas portals and 26 is provided with ball valve 27.
After fragmentation, screening, the boiler tube of packing into adopts electrically heated mode secluding air to be heated to 500～700 ℃, keeps 30～120 minutes with a certain amount of pyrolysis feed of treating.The destructive distillation gas that produces obtains tar and raw gas after the water cooler condensation; Simple in structure, energy consumption is low, easy to operate, be fit to the solid materials of various qualities.
The effect of body of heater is a heat supplied, and Heating element adopts high-temperature electric resistance furnace silk (or globars), and top temperature can reach 1400 ℃, has thermo-efficiency height, fast, the long-lived characteristics of heat-up rate.Burner hearth adopts the turn-up structure, is easy to pick and place boiler tube, and when the cooling demand is arranged, opens upper furnace, makes it fast cooling.
Thermal insulation layer adopts senior refractory fibre to do lagging material, and it is few to have an insulation, light specific gravity, accumulation of heat, the characteristic of burner hearth internal temperature good uniformity.Position easy to wear adopts hardening technique to handle, and makes the stove material durable in use.
Control instruments adopts the digital temperature program control instrument, and PID regulates, and can heat up automatically, is incubated, lowers the temperature, and temperature-controlled precision is high, good reproducibility.Also can directly link to each other, obtaining the real-time curve of temperature, and carry out remote control through jack and softdog with computingmachine USB.
Shell and support adopt advanced numerically-controlled machine to process meticulously, and volume is little, in light weight, human oriented design, good looking appearance.The control bracket height makes boiler tube place height and ground 500-900mm, and in frame bottom castor is set, in order to moving and carrying of device.
Boiler tube is material generation pyrolytic place, must satisfy requirements such as material filling, temperature measuring and sealing.The stove tube is a circular cylindrical cavity, is used to hold various dry distillation mediums, and its bottom is provided with three thermowell and leaves a gas via-hole, and sleeve pipe is used for inserting TM with the monitoring material temperature.Gas via-hole is used in stove, feeding reactant gas, and the time spent does not shut.Be provided with a diameter cylindric capsule slightly littler in the stove tube, process, which is provided with the ventilating pit of cellular distribution, be mainly used in and hold catalyzer by the thin-walled steel plate than stove tube internal diameter.A cellular baffle plate is also established in stove tube exit, in order to stopping material, and has and slows down the effect that material particles is gone out by the destructive distillation band of gas to a certain extent.Bell is provided with destructive distillation gas and portals one, behind a ball valve, links to each other with cooling system with steel pipe, and the steel pipe end is made 24/40 positive ground (with reference to glassware ground standard, down together).The effect of ball valve is: destructive distillation gas overflowed when (1) prevented the high temperature discharging; (2) when using direct-cooled device, prevent suck-back; (3) through changing the size of valve, the control destructive distillation residence time of gas in boiler tube.Body of heater and bell adopt hard metal directly sealing and graphite gasket double seal mode, guarantee that destructive distillation gas can not leak, and both employings connect flange soon and fix, in order to dismounting.
Cooling segment is heat-eliminating medium with water, adopts three kinds of modes altogether, that is: direct-cooled, cold, mix cold.In the design, owing to take modular unit, only need to make preceding two types water cooler and get final product, mixed cooling system can be matched by preceding two kinds of water coolers and form.During concrete the use, can be according to the cooling situation of destructive distillation gas, what cooling units decision needs, and whether is necessary to take to mix cold mode.
Direct-cooled is destructive distillation gas directly to be fed carry out the refrigerative mode in the water.Wherein 1 is Glass tubing, and its upper end is 24/40 cloudy ground, so that cooperate with destructive distillation gas outlet pipe; The inlet pipe of lower end and gas washing bottle is similar, has four little air outlets to be symmetrically distributed, to increase the gas-to-liquid contact area, to strengthen condensation effect.Tetrafluoro joint door is done in direct-cooled device bottom, in order to leave standstill separatory, the reception of back profit.Likewise, can be according to cooling performance, a plurality of water coolers of contacting.The shortcoming of direct-cooled device is to cause profit to mix, and only remains could calculate corresponding pyrolysis oil productive rate behind the standing demix, and because profit directly contacts, cause the amount of pyrolysis water to be difficult to calculate, but the cooling water amount of this mode is less.
Between cold employing coiled pipe cooler, water coolant is walked in the pipe, destructive distillation is made leave with rage outside the pipe.This kind type of cooling can conveniently obtain the amount of material pyrolysis water, is with graduated receiving bottle, product speed and the output that also can observe tar at any time if adopt.Reserved opening on the water cooler can be used to connect all kinds of temperature, pressure detector, according to the requirement of test technology, can record temperature, the pressure of the destructive distillation gas gangway of system, the pressure and other parameters of gas reservoir.
Each water cooler is made by the ultrahard high-boron-silicon glass, and the softening temperature of this kind glass reaches 820 ℃, takes off 560 ℃ of fiery temperature, satisfies the temperature requirement of low-temperature pyrolysis fully.Use glass to do the material of water cooler, can observe the cooling degree of destructive distillation gas in the water cooler at any time, conveniently confirm right the most full water cooler quantity, and glass cleans also more conveniently, outward appearance is also more attractive in appearance.Certainly, also can select for use and not pass through the material of steel as water cooler, then more durable in use, but can not observe the situation in the water cooler.
Whole cooling system is installed on the brandreth, and brandreth can be confirmed the size of brandreth according to the quantity that water cooler is installed by reinforcing bar weldering system.
Natural gas gathering system is mainly a gas-holder; The mode that adopts draining to get gas, after experimental installation was built completion, at first energized dewatered to material; During this period, through T-valve 43 gas-holder is filled water (and being used for analyzing with airbag collection gaseous sample simultaneously).After storage tank was filled water, the swivel tee valve made it to link to each other with cooling system, through the size of by-pass valve control 42 aquifer yields, made and kept pressure-fired (100-1000Pa) in the boiler tube.Gas-holder one side is equipped with glass pipe, calculates the volume of dry distillation gas through the amount of measuring surplus water in the gas tank.
