Description

A kind of waste printed circuit board non-metal powder prepares the device of activated carbon
Technical field
This utility model belongs to field for the treatment of of solid waste, is specifically related to a kind of waste printed circuit board non-metal powder and prepares the device of activated carbon.
Background technology
In recent years, electronic waste has become as the problem that government, electronics industry and the public pay close attention to the most.The quickening updated along with electronic product and the shortening of electronic product life cycle, increasing waste electric products is environmentally safe causes huge threat.As the element that electronic product is the most basic, the safe efficient disposal of waste printed circuit board or recycling become the focus of countries in the world.At present main employing Mechanical Crushing is reclaimed for waste printed circuit board to be dissociated by the metal in wiring board, then by method for separating such as electrostatic, magnetic force, gravity, metal material and nonmetallic materials are separated.Metal dust is worth higher, can the most commercially sell.But few for accounting for the Application way of the non-metal powder of wiring board weight 70%, the most directly fill or simply for the filler as other materials, value is relatively low, cause the significant wastage of resource.At present, waste printed circuit board non-metal powder is prepared absorbent charcoal material as raw material by domestic having been reported.Duan Yuandong et al. is open reports the method using the waste plastics in circuit board to prepare activated carbon, the carbonization temperature of the method 500 DEG C, carbonization time 60 minutes, activation temperature 700 DEG C, soak time 90 minutes, but their not data such as announcement specific surface area preparing gained activated carbon.Yang Ertao et al. is open reports the method preparing activated carbon with waste printed circuit board non-metal powder, the method includes pyrolysis, molding, carbonization and four steps of steam activation, pyrolysis temperature 600 DEG C, pyrolysis time 2 hours, carbonization temperature 800 DEG C, carbonization time 30 minutes, steam activation temperature 850 DEG C, 3 hours steam activation time, the specific surface area of the activated carbon prepared under these conditions is 1019m2/ g, void content is 0.71cm3(commercial activated carbon surface amasss >=500m to/g2/ g, void content >=0.8cm3/g).In order to avoid the preparation process of high temperature carbonization, Kan et al. is the openest reports employing high-temperature water vapor and H3PO4The technology combined is for activating the method that waste printed circuit board non-metal powder prepares activated carbon.The method need not high temperature carbonization step, directly uses 50%H3PO4After activating 12 hours, it is re-activated 0.5 hour under 800 DEG C of high-temperature water vapors, but its activated carbon specific surface area obtained is only 810m2/ g, void content only has 0.6cm3/g。
Utility model content
For solving prior art carbonization temperature height, activation temperature length high, time-consuming, preparation process is many and energy consumption is high deficiency, this utility model provides kind waste printed circuit board non-metal powder and prepares the device of activated carbon.
This utility model adopts the following technical scheme that realization:
A kind of waste printed circuit board non-metal powder prepares the device of activated carbon, and described device includes CO2Gas cylinder, CO2Gas cylinder is connected with high-pressure pump, reactor, air relief valve, solid-liquid separation bottle and H in turn by pipeline3PO4Returnable bottle;Being provided with extraction valve bottom described reactor, reactor is provided with heater;H3PO4Returnable bottle passes through pipeline coupled reaction still;Solid-liquid separation bottle connects CO by pipeline2Gas cylinder.
Advantage the most of the present utility model is:
This utility model avoids the processes such as the high temperature carbonization of prior art needs, high-temperature activation, and step is few, and preparation time is short, and energy consumption is low, and the activated carbon specific surface area and the void content that prepare are above existing method.
Accompanying drawing explanation
Fig. 1 is reaction unit figure of the present utility model.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, and it is understandable to make features described above of the present utility model, purpose and advantage become apparent from, below in conjunction with embodiment, this utility model is further explained explanation, it should be noted that, all embodiments listed here are merely illustrative, are not meant to be defined this utility model scope.
Embodiment 1
As it is shown in figure 1, a kind of waste printed circuit board non-metal powder prepares the device of activated carbon, described device includes CO2Gas cylinder 1, CO2Gas cylinder 1 is connected with high-pressure pump 2, reactor 3, air relief valve 7, solid-liquid separation bottle 5 and H in turn by pipeline3PO4Returnable bottle 6 is constituted;Being provided with extraction valve bottom described reactor 3, reactor 3 is provided with heater 4;H3PO4Returnable bottle 6 is by pipeline coupled reaction still 3;Solid-liquid separation bottle 5 connects CO by pipeline2Gas cylinder 1.
This utility model using method is as follows:
By waste printed circuit board non-metal powder and 30%H3PO4Adding in reactor 3, solid-to-liquid ratio controls at 1:3g/mL, airtight heating, and temperature controls at 35 DEG C.Meanwhile, CO is opened2Gas cylinder 1, is passed through the CO after high-pressure pump 2 pressurizes2, Stress control is at 7.5MPa.After reacting 20 minutes, by controlling the extraction valve of reactor 3 outlet at bottom, pressure is reduced to normal pressure, CO through air relief valve 7 bottom reactor by reactant mixture the most afterwards2Gas recycling use, solid-liquid mix products enters solid-liquid separation bottle 5 and carries out solid-liquid separation, isolated H3PO4Recovered liquid enters H3PO4Returnable bottle 6 also recycles.Then, the solid product obtained is activated 20 minutes under nitrogen atmosphere in 200 DEG C of tube type resistance furnaces, be cooled to room temperature afterwards and take out after solid-liquid separation, scrubbed, 105 DEG C of dried acquisition absorbent charcoal materials.Analyzing specific surface area and the void content of the absorbent charcoal material of preparation, result shows: the specific surface area of the activated carbon prepared under these conditions reaches 1133m2/ g, void content is 1.15cm3/g。
