Description
Technical field
The present invention relates to one and the present invention relates to physics, chemical experiment, particularly, relate to a kind of experimental provision providing the water-bath energy-saving and environment friendly of the preparation biodiesel of steady temperature to react.
Background technology
Oil is the main body of countries in the world energy-consuming, and along with the development of modern industry, to the demand of oil by increasing, and earth fossil resources is limited.Biodiesel combustion product environmental pollution is little, if be applied to boats and ships, more can meet now in the world to the strict demand of diesel emission, but the shortcomings such as preparation bio oil cost is high, its chemical composition complexity bring very big obstruction to the process of bio oil Some substitute Conventional petroleum products, the cost of adding current production biodiesel, apparently higher than ordinary diesel oil, also becomes the bottleneck of biodiesel industrialized utilization.
Summary of the invention
For solving the problems referred to above that prior art exists, the present invention will design a kind of experimental provision of preparation biodiesel of low cost.
To achieve these goals, technical scheme of the present invention is as follows:
Prepare an experimental provision for biodiesel, comprise stirrer, stir small machine, iron stand, there-necked flask, temperature sensor, controller, water bath and solar water heater; Described water bath adopts heat-barrier material coated, and described iron stand is positioned at the side of water bath; Described there-necked flask to be positioned in water bath and to be supported by iron stand, described stirrer is deep in there-necked flask by a mouth of there-necked flask, the upper end of stirrer is stirred small machine and is connected, and stirring small machine is fixed on and is fixed on iron stand by connecting rod; Described temperature sensor is arranged in water bath, and temperature sensor is connected with controller by data wire; Described solar water heater is connected with water bath through magnetic valve by pipeline; Described controller is also connected with magnetic valve.
Heat-barrier material of the present invention is industrial waste foam.
Controller of the present invention is single-chip microcomputer, and controller can receive the temperature information of temperature sensor, and is contrasted by the bath temperature that this temperature and experiment set, and controls the magnetic valve feedwater of solar water heater, controls the temperature of water-bath with this.If bath temperature is too low, controller Controlling solenoid valve provides high-temperature water, if bath temperature is too high, then controller Controlling solenoid valve provides cold water.
Stirring small machine of the present invention controls the mixing speed of stirrer.
Compared with prior art, the present invention has following beneficial effect:
1, the present invention adopts waste cooking oil to be feedstock oil, and industry byproduct flyash is catalyst, greatly can reduce the cost of production biodiesel, and meanwhile, the required energy of experiment provides economic environmental protection by solar energy.
2, owing to present invention employs the method for solar energy heating water-bath, the object reducing production biodiesel cost is achieved.
3, due to present invention employs waste oil, industrial flyash " the two expense of industry " as reactant, achieves the object reducing production biodiesel cost.
Accompanying drawing explanation
The present invention is drawings attached 1 only, wherein:
Fig. 1 is the preparation biodiesel experimental provision of low cost of the present invention.
In figure: 1, stirrer, 2, stir small machine, 3, iron stand, 4, there-necked flask, 5, temperature sensor, 6, controller, 7, water bath, 8, solar water heater.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
Operation principle of the present invention is as follows: as shown in Figure 1, first utilizes solar heater 8 heating water, utilizes temperature controller 6 to set the heating-up temperature needed for testing, and is incubated with the heat-barrier material of water bath 7.When temperature is elevated to the temperature of esterification setting, the there-necked flask 4 that reactant is housed is put in water bath 7.Should be understood that, in there-necked flask 4, reactant liquid level below the liquid level of water bath 7, should ensure the reaction temperature of reactant.In the present invention, reactant is waste oil, and its acidity is higher, in order to improve reaction rate, therefore adopts the acid flyash of industry byproduct nanoscale as catalyst, in order to realize being separated of catalyst and biodiesel and glycerine, catalyst is done magnetization treatment.
For the ease of dissolving each other of waste oil and alcohol, arrange by the stirrer 1 stirring small machine 2 and drive, stirrer 1 comprises rotating shaft and is arranged on the blade on this rotating shaft.
In order to simulate the impact of different bath temperatures on biodiesel conversion rate, can in water bath 7 set temperature sensor 5.And the design temperature experimentally required, utilize temperature controller 6 pairs of bath temperatures to control.
After utilizing illustrated esterification experiment, the biodiesel that reaction generates can be taken out from there-necked flask 4, the performance (e.g., Cetane number, viscosity etc.) of biodiesel is detected.
Below the preferred embodiment of the present invention is described in detail by reference to the accompanying drawings; but; the present invention is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition, each the concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode.In order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible combination.
In addition, also can be combined between various different embodiment of the present invention, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
