Abstract
The utility mode discloses a device for recovering methanol from crude glycerine by utilizing solar energy. The device comprises a solar collector, an electric heater, a temperature control system, a methanol distiller, a methanol storage cylinder, a condenser, a water tank and a heat transfer oil storage cylinder. According to the device for recovering the methanol from the crude glycerine by utilizing the solar energy, heat transfer oil is preheated by utilizing the solar energy and then is electrically heated to be up to a set temperature. The hot heat transfer oil is used for heating the methanol distiller in order to evaporate the methanol, and methanol steam is cooled by a condenser and then flows into the methanol storage cylinder. The hot transfer heat oil passes through the methanol distiller to heat water in the water tank and then returns to the heat transfer oil storage tank to absorb the solar energy. The device for recovering the methanol from the crude glycerine by utilizing the solar energy is simple in structure, reliable in performance, low in construction cost and good in effect, and realizes an effect of energy conservation.
Description
Technical field
The utility model relates to a kind of solar heat collector, is specifically related to a kind of device that utilizes solar energy to reclaim methyl alcohol from crude glycerine.
Background technology
It is one of huge bottleneck of facing of present whole world economic development that the energy lacks.Compare with petrifaction diesel; biodiesel has series of advantages; such as renewable, clean environmental protection, nontoxic, the discharging of more abundant, the net carbon dioxide of burning is almost nil etc.; the development biodiesel not only helps to break through the predicament of China's energy sleepiness, can also reduce human greenhouse and the environmental protection crisis that faces.The preparation of biodiesel is generally carried out ester exchange reaction by animal and plant fat and methyl alcohol and is realized, in the production process of biodiesel, can produce the crude glycerine of 10-15%.Contain glycerine, grease, biodiesel, methyl alcohol and a small amount of inorganic salts in the crude glycerine.In order to reduce the processing cost of biodiesel, methyl alcohol contained in the crude glycerine must be reclaimed, and is recycling.Traditional Methanol Recovery method employing steam or electrically heated mode are evaporated the methyl alcohol in the crude glycerine, recycle after the cooling, and the energy consumption of this process is higher, causes the processing cost of biodiesel higher.
Summary of the invention
For the problems referred to above that prior art exists, the purpose of this utility model is to provide a kind of device that reclaims effectively, cheaply methyl alcohol from crude glycerine.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of device that utilizes solar energy to reclaim methyl alcohol from crude glycerine comprises solar collector, electric heater, temperature control system, methyl alcohol distiller, methyl alcohol storage tank, condenser, water tank, conduction oil storage tank; Solar collector is connected with the conduction oil storage tank, and temperature control system connects electric heater, and the methyl alcohol distiller is connected with electric heater, and condenser connects methyl alcohol distiller and methyl alcohol storage tank, and water tank connects methyl alcohol distiller and conduction oil storage tank.
Solar energy is a kind of free the Nature energy, and is inexhaustible.But in the time that does not have the sun, such as overcast and rainy and night, people can't obtain solar energy, so we adopt electrically heated mode to remedy the weak point that natural conditions change.The crude glycerine that produces in the production of biodiesel process contains the compositions such as glycerine, methyl alcohol, grease and a small amount of inorganic salts.After pH value adjusting (5-7), need to reclaim the methyl alcohol in the crude glycerine.Under 1atm, the boiling point of glycerine is 182
oC, the boiling point of water are 100
oC, the boiling point of methyl alcohol are 65
oC, the boiling point of three kinds of components differs greatly, and by air-distillation, just can obtain higher degree (〉 95%) methyl alcohol, in the production of biodiesel process, recycle.
Utilize the conduction oil in the solar energy preheating conduction oil storage tank, conduction oil is heated to 150-200 by electrical heating after entering electric heater again
OCCrude glycerine in the thermal conductance deep fat heating methanol distiller is to 65-75
OC, evaporating methyl alcohol, methanol steam enters the methyl alcohol storage tank after cooling off through condenser.Heated the conduction oil of methyl alcohol distiller through water tank, the water in the heating water tank returns at last the conduction oil storage tank and absorbs solar energy.After the methyl alcohol evaporation fully, the hot water in the water tank enters the methyl alcohol distiller, reduces the viscosity of glycerine.
A kind of device that utilizes solar energy to reclaim methyl alcohol from crude glycerine of the present utility model is compared with existing technology, and has following beneficial effect:
The utility model takes full advantage of solar energy and heats crude glycerine, reclaims methyl alcohol.The utility model is simple in structure, dependable performance, cost are low, effective, has played the effect of energy savings.
Description of drawings
Fig. 1 is a kind of schematic diagram that utilizes solar energy to reclaim methyl alcohol from crude glycerine of the present utility model.
Among the figure: the 1-solar collector; The 2-electric heater; The 3-temperature control system; The 4-valve; The 5-valve; 6-methyl alcohol distiller; 7-methyl alcohol storage tank; The 8-condenser; The 9-water tank; The 10-valve; The 11-valve; The 12-Heat-transfer Oil Pump; 13-conduction oil storage tank.
The specific embodiment
Next explain below with reference to Figure of description a kind of device that utilizes solar energy to reclaim methyl alcohol from crude glycerine of the present utility model being done.
Adopt the device that utilizes solar energy from crude glycerine, to reclaim methyl alcohol of said structure to work as follows: conduction oil is packed in the conduction oil storage tank 13, Open valve 11 and Heat-transfer Oil Pump 12 are utilized solar collector 1 to accept solar energy and are heated conduction oil in the conduction oil storage tank 13.Start temperature control system 3, set conduction oil outlet temperature 150-200
OC, Open valve 11, opening electric heater 2(electrically heated rod and electrical heating wire etc.) with heat-conducting oil heating to the temperature that sets.With the crude glycerine that produces in the production of biodiesel process methyl alcohol distiller 6 of packing into, the pH that regulates crude glycerine is 5-7, starts and stirs, start condenser 8, Open valve 4, the methyl alcohol start vaporizer in the crude glycerine, after starting condenser 8 coolings, the liquid methyl alcohol storage tank 7 that flows into of methyl alcohol.Water is packed in the water tank 9, with heat-conducting oil heating water tank 9.After the evaporation fully of methyl alcohol in the crude glycerine, open valve 5, the hot water of adding crude glycerine weight 10-20% in the crude glycerine.Valve-off 5, valve 4 and valve 10 are discharged remaining crude glycerine from methyl alcohol distiller 6.
The above embodiment is a kind of of the more preferably concrete embodiment of the utility model, and the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacement all should be included in the protection domain of the present utility model.
