Description
Technical field
The utility model relates to a kind of device removing an acidic catalyst in methanol gas, particularly in the catalyzed reaction of production of biodiesel process, belongs to technical field of biochemical industry.
Background technology:
Utilizing sewer oil to produce in biodiesel process usually uses the vitriol oil as catalyzer, because it has catalytic efficiency high, speed of response is fast, advantage with low cost is widely used, but produce in reaction process simultaneously containing in an acidic catalyst methanol gas to the etching problem of equipment also very serious, particularly to the corrosion of methanol condenser and dilute methanol rectification and purification device, become in industry the problem being all the time all difficult to solve.
Methanol gas containing a small amount of sulfuric acid in traditional technology out directly enters methyl alcohol pipe bundle condenser from the gas-guide pipeline of enamel glass reactor, and generate the dilute methanol containing dilute sulphuric acid through condensation, dilute methanol obtains 99.8% methyl alcohol through rectification and purification, then continues reuse.The dilute methanol gas containing dilute sulphuric acid generated in this technique can produce corrosion to condenser and methanol rectification purifying plant; Meanwhile, because the volumetric molar concentration of sulfuric acid in whole reaction system declines gradually, speed of response slows down; The time of surveying the single reactor reaction of coarse biodiesel that traditional technology is produced factually is 6 hours/still, and electricity consumption 50 KWhs/ton, with steam 1 ton/ton, with 0.7 ton/ton, water, not only equipment maintenance cost 12 yuan/ton, loses time but also waste energy.
The utility model provides a kind of device removing an acidic catalyst in methanol gas, be exactly between enamel glass reactor and condenser, increase a separator, the separation contained through separator in the methanol gas of an acidic catalyst produced from enamel glass reactor like this, acidic catalyst agent concentration is obviously declined, then corrosion would not be produced to pipe bundle condenser and methanol rectification purifying plant when passing into pipe bundle condenser and methanol rectification purifying plant; Simultaneously due to an acidic catalyst reuse, make whole reaction system to positive reaction orienting response, shorten the reaction times, saved the energy; Survey factually, the time of single reactor reaction is 4 hours/still, shortens 33% than traditional technology; Coarse biodiesel electricity consumption 33 KWhs/ton, brownout 34%; With steam 0.72 ton/ton, save 28%; With 0.4 ton/ton, water, save 43%; Equipment maintenance cost 4 yuan/ton, save 67%, effect is fairly obvious.
Summary of the invention
A kind of device removing an acidic catalyst in methanol gas is made up of enamel glass reactor, separator, condenser, methanol rectification purifying plant; Described enamel glass reactor is common commercially available reactor; Described separator is made up of shell, liner, a pressure rack, filler; Described shell is made up of carbon steel Q235 material; Described liner is polytetrafluoroethylmaterial material, thickness 6mm; A described pressure rack is the screen of stainless steel, for placing and fixing filler; Described filler is tetrafluoroethylene corrugated material block, block height 100mm; Filler in separator arranges like this: arrange a pressure rack in the separator, place tetrafluoroethylene ripple packing above, arrange 8 layers altogether, place between layers, every layer height 100mm, total height 800mm in three-dimensional right-angled intersection; A pressure rack screen pressure rack is propped up in using above of filler, prevents gas percussion filler to be shifted; The specific surface area of filler is 500m
2/ m
3; Described condenser is common 316L stainless steel pipe bundle condenser; Described methanol rectification purifying plant is common 316L stainless steel rectifying purifying plant; Removing the device of an acidic catalyst in methanol gas is install like this: enamel glass reactor top airway connects a separator bottom inlet mouth, and separator top airway connects pipe bundle condenser inlet mouth, and condenser air outlet connects methanol rectification purifying plant; Separator bottom fluid flow tube connects enamel glass reactor.
A kind of to remove the device of an acidic catalyst in methanol gas be like this work: the methanol gas containing dilute sulphuric acid derived from enamel glass reactor top is introduced into separator bottom, methanol gas containing dilute sulphuric acid is less than the methanol gas of the lower concentration dilute sulphuric acid of 200ppm through separator separation generation liquid dilute sulphuric acid and concentration, and liquid dilute sulphuric acid is got back in reactor again through bottom liquid stream pipe; Containing lower concentration dilute sulphuric acid methanol gas to derive from the top of separator and enter pipe bundle condenser again, after condensation liquefaction, enter methanol rectification purifying plant, finally methanol purification be greater than 99.8% to concentration, reuse.
The beneficial effects of the utility model: to use dilute sulphuric acid density loss in the utility model energy production of biodiesel process the dilute sulphuric acid methanol gas of concentration 800-1200PPM through separator to below 200PPM, enter condenser and methanol purification device again, thus reach and reduce the corrosion of dilute sulphuric acid to condenser and purifying plant, extension device working life, cost-saving, continue catalyzed reaction because the sulfuric acid separated returns in reactor simultaneously, ensure that the volumetric molar concentration of an acidic catalyst in reaction system, make whole reaction system to positive reaction orienting response, shorten the reaction times and saved the energy.Survey factually, the time of single reactor reaction is 4 hours/still, shortens 33% than traditional technology; Coarse biodiesel electricity consumption 33 KWhs/ton, brownout 34%; With steam 0.72 ton/ton, save 28%; With 0.4 ton/ton, water, save 43%; Equipment maintenance cost 4 yuan/ton, save 67%, effect is fairly obvious.
