Abstract
The utility model relates to a semi-continuous acrylic waste oil cracking device. The semi-continuous acrylic waste oil cracking device is characterized by comprising an acrylic acid waste oil storage tank, a cracking reactor, a condenser, a vacuum system, an acrylic finished product tank and a liquid seal device, wherein the acrylic acid waste oil storage tank is connected with a material inlet of the cracking reactor through a pipeline, a material outlet of the cracking reactor is connected with the condenser through another pipeline, the condenser is connected with the vacuum system, an outlet of the condenser is connected with the liquid seal device, and a material outlet of the liquid seal device is connected with the acrylic finished product tank. Under the condition that the investment of the equipment is not increased, the semi-continuous acrylic waste oil cracking device realizes the semi-continuous cracking operation, single cracking quantity of acrylic waste oil is increased to 400% from 80%, the cracked acrylic in different grades can be separated during the cracking process, by adopting the continuous feeding model, i.e. the polymerization inhibitor continuous feeding, the semi-continuous acrylic waste oil cracking device can effectively prevent the aggregating, and effectively ensures the safe production.
Description
Technical field
The utility model relates to the semicontinuous cracker of a kind of vinylformic acid waste oil, belongs to the chemical industry equipment field.
Background technology
Vinylformic acid is in dehydration and rectifying, part acrylic acid is arranged along with the prolongation of time and the rising of temperature, can become the polymkeric substance of acrylic acid dimer and other form gradually, wherein acrylic acid dimer (β acyloxy propionic acid) can be decomposed into bimolecular vinylformic acid at 150 ℃, and this principle of industrial usefulness is carried out the cracking of vinylformic acid waste oil.If but if knock off cracking technology between the vinylformic acid employing,,, can cause the acroleic acid polymerization in cracking still or the cracker along with time lengthening because stopper wherein at high temperature can consume very soon, have a strong impact on production efficiency and safety.
Summary of the invention
According to the deficiencies in the prior art, the technical problems to be solved in the utility model is: provide a kind of vinylformic acid waste oil semicontinuous cracker, it is semicontinuous to make that the cracking of vinylformic acid waste oil can realize, enhances productivity and safety coefficient.
The technical scheme that its technical problem that solves the utility model adopts is: provide a kind of vinylformic acid waste oil semicontinuous cracker, it is characterized in that comprising: acrylic acid waste oil tank, cracking still, condenser, vacuum system, vinylformic acid finished product jar and liquid seal device, the acrylic acid waste oil tank links to each other with the feeding mouth of cracking still by pipeline, the discharge port of cracking still is connected with condenser by pipeline, condenser connects vacuum system, condensator outlet connects liquid seal device, and the liquid seal device discharge port connects vinylformic acid finished product jar.
The beneficial effects of the utility model are:
1, do not increasing under the large equipment investment situation, realizing semicontinuous cracking operation;
2, vinylformic acid waste oil single burst size rises to 400% by 80% of original still volumetric quantity;
3 and in cracking process the effective separately cracking vinylformic acid of different grades;
4, owing to adopt the continuous charging mode, be equal to the continuous adding of stopper, effectively prevented the polymeric generation, effectively having ensured keeps the safety in production carries out.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 is the acrylic acid waste oil tank; 2 is cracking still; 3 is condenser; 4 is vacuum system; 5 is vinylformic acid finished product jar; 6 is liquid seal device.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, the utility model comprises: acrylic acid waste oil tank 1, cracking still 2, condenser 3, vacuum system 4, vinylformic acid finished product jar 5 and liquid seal device 6, acrylic acid waste oil tank 1 links to each other by the feeding mouth of pipeline with cracking still 2, the discharge port of cracking still 2 is connected with condenser 3 by pipeline, condenser 3 connects vacuum system 4, condenser 3 outlets connect liquid seal device 6, and liquid seal device 6 discharge ports connect vinylformic acid finished product jar 5.
During use, disposable input vinylformic acid waste oil is still volumetrical 20%～40% in cracking still 2 from acrylic acid waste oil tank 1, open vacuum system 4,-0.05～-heat up under the 0.06Mpa and control still temperature at 150～160 ℃, when vinylformic acid distillates, beginning adding acrylic acid dimer continuously to cracking still 2 in, and guarantee to distillate reason and add-on balance to the greatest extent the time, material enters condenser 3, enters liquid seal device 6 then, enters vinylformic acid finished product jar 5 at last.
