Abstract
The utility model relates to an oxidative dehydrogenation tail gas recovery device, which belongs to the field of chemical processes. The oxidative dehydrogenation tail gas recovery device comprises a light hydrocarbon adsorption tower, an emptying cooler I, an emptying cooler II, an absorption oil recovery tank and a recovery oil conveying pump, wherein the light hydrocarbon adsorption tower is connected with the emptying cooler I and the emptying cooler II through pipelines in sequence; discharge ports of the emptying cooler I and the emptying cooler II are connected with the absorption oil recovery tank through pipelines; and a discharge port of the absorption oil recovery tank is connected with the recovery oil conveying pump through a pipeline. After the tail gas of the device is subjected to C6 oil adsorption, 4 tons of C6 oil can be adsorbed each day, and 1,400 tons of C6 oil can be recovered a year, so that the raw material is saved, the production cost is reduced, the environment is protected, and the solvent oil is recovered to reduce energy consumption.
Description
Technical field
The utility model relates to a kind of oxidative dehydrogenation device for recovering tail gas, belongs to the chemical process field.
Background technology
In the present chemical field, often have tail gas and directly be discharged into the situation in the atmosphere, especially problem is particularly outstanding in oxidation degassing tail gas; At first in the oxidative dehydrogenation tail gas discharging directly into atmosphere, caused the waste of carbon six oil, the waste of raw material; This just is equivalent to the raising of product cost, has improved production cost virtually, and there is very big peculiar smell in the tail gas that is discharged in the atmosphere; Environment has been caused very big pollution, and this theory with environmental protection is mutually not compound.
Summary of the invention
According to the deficiency of prior art, the technical problem that the utility model will solve is: a kind of oxidative dehydrogenation device for recovering tail gas is provided, and carbon six oil of carrying secretly in the absorption tail gas reduce energy resource consumption, have avoided environmental pollution.
The utility model solves the technical scheme that its technical problem adopted: a kind of oxidative dehydrogenation device for recovering tail gas is provided; It is characterized in that comprising: lighter hydrocarbons adsorption tower, emptying cooler I, emptying cooler II, the oily recycling can of absorption and recovered oil delivery pump; The lighter hydrocarbons adsorption tower connects emptying cooler I and emptying cooler II successively through pipeline; The discharging opening of emptying cooler I and emptying cooler II is connected the oily recycling can of absorption through pipeline, and the discharging opening that absorbs oily recycling can connects the recovered oil delivery pump through pipeline.
Described lighter hydrocarbons adsorption tower is that 2～5 series connection are used.
Described lighter hydrocarbons adsorption tower is that 2 parallel connections are used.
During use, when lighter hydrocarbons adsorption tower normal sorption put into production, the hydrogenation dehydrogenated tail gas was got into by the lighter hydrocarbons adsorption tower, and the tail gas after the absorption is discharged by aiutage.
When carbon six oil analysis exceeded standard in the adsorption tower tail gas, the lighter hydrocarbons adsorption tower that absorption carbon six oil are wherein exceeded standard cut out regeneration, feeds vapour cooking; With the tail gas process emptying cooler I of boiling, emptying cooler II, emptying after twice cooling; Wherein carbon six oil that get off of condensation have been come and have been absorbed oily recycling can; Regeneration ending when the liquid level that absorbs oily recycling can no longer goes up utilizes the recovered oil delivery pump, and carbon six oil that reclaim are got to the charging again of device head tank.
The beneficial effect of the utility model is: after device exhaust was carried out carbon six oil absorption, every day, adsorbable carbon six oil were 4 tons, and recyclable carbon six oil were 1400 tons in 1 year; Conservation; Reduced production cost, effectively protected environment, and reclaimed solvent naphtha and reduced energy resource consumption.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
1 is the lighter hydrocarbons adsorption tower among the figure; 2 are emptying cooler I; 3 are emptying cooler II; 4 for absorbing oily recycling can; 5 is the recovered oil delivery pump.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
Embodiment 1
As shown in Figure 1; The utility model comprises: lighter hydrocarbons adsorption tower 1, emptying cooler I 2, emptying cooler II 3, the oily recycling can 4 of absorption and recovered oil delivery pump 5; Lighter hydrocarbons adsorption tower 1 connects emptying cooler I 2 and emptying cooler II 3 successively through pipeline; The discharging opening of emptying cooler I 2 and emptying cooler II 3 is connected the oily recycling can 4 of absorption through pipeline, and the discharging opening that absorbs oily recycling can 4 connects recovered oil delivery pump 5 through pipeline.
Lighter hydrocarbons adsorption tower 1 is that 2 series connection are used in the present embodiment.
During use, when lighter hydrocarbons adsorption tower 1 normal sorption put into production, the hydrogenation dehydrogenated tail gas was got into by lighter hydrocarbons adsorption tower 1, and the tail gas after the absorption is discharged by aiutage.
When carbon six oil analysis exceeded standard in the lighter hydrocarbons adsorption tower tail gas, that lighter hydrocarbons adsorption tower 1 that absorption carbon six oil are wherein exceeded standard cut out regeneration, feeds vapour cooking; Tail gas process emptying cooler I 2 and emptying cooler II 3 with boiling; Emptying after twice cooling, wherein carbon six oil that get off of condensation have been come and have been absorbed oily recycling can 4, regeneration ending when the liquid level that absorbs oily recycling can 4 no longer goes up; Utilize recovered oil delivery pump 5, carbon six oil that reclaim are got to the charging again of device head tank.
Embodiment 2
Lighter hydrocarbons adsorption tower 1 is that 2 parallel connections are used in the present embodiment.
