Abstract
The utility model belongs to tail gas treatment devices, and particularly relates to a device for recycling butanol/octanol tail gas. The device consists of a tail gas storage tank, a reaction tank and an absorption tower, wherein a tail gas inlet is arranged at the lower end of the tail gas storage tank, a tail gas outlet of the tail gas storage tank is connected with a gas inlet of the reaction tank, a gas outlet of the reaction tank is connected with a gas inlet of the absorption tower, a liquefied gas supplement pipeline is arranged between the reaction tank and the absorption tower, a medical dosing device is arranged at the upper part of the reaction tank, and an extracted gas outlet and a waste gas outlet are arranged at the upper part of the absorption tower. According to the device, before entering the absorption tower, the tail gas firstly enters the reaction tank, impurities in the tail gas are removed by a series of reactions such as dosing, so that the finished product of liquefied gas obtained in the later period does not contain other gas impurities; furthermore, the device is additionally provided with the liquefied gas supplement pipeline, when the content of the tail gas in the storage tank is low, the liquefied gas can be supplemented into the absorption tower by regulating a control valve on the liquefied gas supplement pipeline, so that circulation in the absorption tower is smooth, and the output of the liquefied gas is increased.
Description
Technical field
The utility model relates to exhaust gas processing device, relates in particular to a kind of fourth octanol device for recovering tail gas.
Background technology
Butanols and octanol are due to the method production that can synthesize with hydroxyl in same set of device, therefore custom becomes the fourth octanol.The fourth octanol is water white transparency, inflammable oily liquids, has special smell, can form azeotropic mixture with water and multiple compounds, and moderate toxicity is all arranged.The fourth octanol is the important source material of synthetic fine chemical product, mainly for the production of plasticizer, solvent, dehydrating agent, defoamer, dispersant, flotation agent, petroleum additive and synthetic perfume etc.Contain a large amount of propylene, propane, mixing butyraldehyde in fourth octanol tail gas; recovery value is very large; existing fourth octanol device for recovering tail gas is when tail gas holding vessel inner exhaust gas content is low; often can cause the tower reactor circulation in the absorption tower not smooth; the liquefied gas discharging enters torch; cause a large amount of loss of product liquefied gas, cause a large amount of wastes, affected the output of vent gas treatment.And existing fourth octanol device for recovering tail gas can not done further processing to fourth octanol tail gas, just enters into to carry out in the absorption tower separating of liquefied gas and incondensable gas, makes the phenomenon that has impurity in the resulting liquefied gas of processing.
The utility model content
The utility model is intended to for the deficiency that exists in background technology, and propose a kind of simple in structure, can improve the fourth octanol device for recovering tail gas of liquefied gas output.
Fourth octanol device for recovering tail gas of the present utility model, to be consisted of by tail gas holding vessel, retort and absorption tower, the lower end of tail gas holding vessel is provided with the tail gas import, the air inlet of the tail gas outlet coupled reaction tank of tail gas holding vessel, the gas outlet of retort connects the air inlet on absorption tower, the pipeline on retort and absorption tower is provided with liquefied gas and augments pipeline, and the top of retort is provided with chemicals dosing plant, the bottom is provided with exhaust outlet c, and the top on absorption tower is provided with extracts gas outlet and waste gas outlet.
As further improvement of the utility model, connected heater on the absorption tower.
As further improvement of the utility model, be provided with valve a between retort and heater.
As further improvement of the utility model, liquefied gas is augmented pipeline and is provided with control valve b.
Fourth octanol device for recovering tail gas of the present utility model, reasonable in design, before tail gas enters into the absorption tower, at first enter into retort, by the impurity in the reflection removal tail gas of some row such as dosing, make in the liquefied gas of later stage finished product and do not contain other foreign gases, the utility model has additional liquefied gas and augments pipeline simultaneously, when holding vessel inner exhaust gas content is low, augment by regulating liquefied gas the effect that control valve on pipeline is accomplished supply liquefied gas in the absorption tower, make circulation smoothness in the absorption tower, increase the output of liquefied gas.
Description of drawings
Fig. 1 is fourth octanol device for recovering tail gas structural representation of the present utility model.
The specific embodiment
Below in conjunction with 1 pair of fourth octanol device for recovering tail gas of the present utility model of accompanying drawing, be described further:
