Abstract
The utility model discloses a recovery tower that noncondensable gas that is used for alkanisation equipment to generate, including body of the tower 1, 1 upper end of body of the tower is provided with heat exchanger 2, and 2 belows on the heat exchanger on 1 top of body of the tower are provided with filter screen 3, and the body of the tower of 3 tops of filter screen is provided with exhaust hole 4, and 3 belows of filter screen are provided with alkali lye dispenser 5, and 5 belows of alkali lye dispenser are provided with alkali lye baffle 6, and alkali lye baffle 6 is provided with the gas pocket, 1 lower part of body of the tower is provided with gaseous phase distributor 7, and gaseous phase distributor 7 and alkali lye baffle are provided with heat exchanger 28 between 6, the 1 inside polytetrafluoroethylene regular packing that adopts of body of the tower. According to the above technical scheme, the beneficial effects of the utility model comprises: , simple structure, reasonable in design, the temperature that reduces the noncondensable gas is with acid so that collect to proceed alkanisation production with the great alkanisation raw materials gas separation of the molecule that carries in the noncondensable gas.
Description
Technical field
This utility model relates to a kind of fixed gas recovery tower, particularly relates to the recovery tower of a kind of fixed gas generated for alkylation equipment.
Background technology
In petroleum refining industry, alkylation process is mainly for the production of the blending component of high-knock rating gasoline, and in alkylation production equipment, fixed gas needs to be collected by recovery tower.Fixed gas reclaims and takes high pressure cryogenic separation at present, but the aobvious acidity of alkyl plant fixed gas, the tower internals being generally separated does not adapts to, and alkylation is exothermic reaction, and the highest certain corrosivity of temperature is the strongest.
Utility model content
This utility model is for the deficiency existing for prior art, and provides a kind of simple in construction, reasonable in design, makes recovery more thorough, solves the recovery tower of the fixed gas of etching problem simultaneously.
To achieve these goals, this utility model provides the recovery tower of a kind of fixed gas generated for alkylation equipment, including tower body, described tower body upper end is provided with heat exchanger, it is characterized in that, being provided with filter screen below the heat exchanger on described tower body top, the tower body above described filter screen is provided with steam vent, it is provided with alkali liquor dispenser below described filter screen, below described alkali liquor dispenser, is provided with alkali liquor baffle plate；Described tower body bottom is provided with gaseous distributer, is provided with heat exchanger two between described gaseous distributer and described alkali liquor baffle plate.
Wherein, described alkali liquor baffle plate is provided with pore.
Described tower body is internal uses politef structured packing.
During work, the fixed gas that alkylation equipment generates is entered tower body bottom by gaseous distributer, starts to float, and tentatively lowers the temperature via heat exchanger two and continues to rise；The fixed gas that the alkali liquor water smoke that alkali liquor dispenser spreads generates with alkylation equipment downwards from tower body top contacts, and neutralizes the acidity of the fixed gas that alkylation equipment generates.Alkali liquor water smoke falls into alkali liquor baffle plate and is buffered, and the fixed gas continuing to generate with alkylation equipment reacts；Fixed gas after neutralization continues upward through alkali liquor water smoke, then wears filter screen, and the steam vent above tower body enters collects link.Meanwhile, the gas molecule that moieties is bigger condenses into liquid and continues the raw material as alkylation equipment.
The beneficial effect of this programme can be learnt according to the narration of such scheme, and simple in construction is reasonable in design, reduces the temperature of fixed gas and acid to collect, and separated by raw material for alkylation gas bigger for the molecule carried in fixed gas and proceed alkylation and produce.Heat exchanger two is set and reduces the temperature of fixed gas, make fixed gas that the corrosivity on tower body top to be reduced.Alkali liquor dispenser is provided above filter screen, and the fixed gas making tower body discharge decreases steam.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure, 1, tower body；2, heat exchanger；3, filter screen；4, steam vent；5, alkali liquor dispenser；6, alkali liquor baffle plate；7, gaseous distributer；8, heat exchanger two.
Detailed description of the invention
For the technical characterstic of this programme can be clearly described, below by detailed description of the invention, this programme is illustrated.
As shown in Figure 1, the present embodiment is the recovery tower of a kind of fixed gas generated for alkylation equipment, including tower body 1, tower body 1 upper end is provided with heat exchanger 2, being provided with filter screen 3 below the heat exchanger 2 on tower body 1 top, the tower body above filter screen 3 is provided with steam vent 4, is provided with alkali liquor dispenser 5 below filter screen 3, being provided with alkali liquor baffle plate 6 below alkali liquor dispenser 5, alkali liquor baffle plate 6 is provided with pore；Tower body 1 bottom is provided with gaseous distributer 7, is provided with heat exchanger 28 between gaseous distributer 7 and alkali liquor baffle plate 6；Tower body 1 is internal uses politef structured packing.
During work, the fixed gas that alkylation equipment generates is entered tower body 1 bottom by gaseous distributer, starts to float, and tentatively lowers the temperature via heat exchanger 28 and continues to rise；The fixed gas that the alkali liquor water smoke that alkali liquor dispenser 5 spreads generates with alkylation equipment downwards from tower body top contacts, and neutralizes the acidity of the fixed gas that alkylation equipment generates.Alkali liquor water smoke falls into alkali liquor baffle plate 6 and is buffered, and the fixed gas continuing to generate with alkylation equipment reacts；Fixed gas after neutralization continues upward through alkali liquor water smoke, then wears filter screen 3, and the steam vent 4 above tower body 1 enters collects link.Meanwhile, the gas molecule that moieties is bigger condenses into liquid and continues the raw material as alkylation equipment.
This utility model can pass through or use prior art to realize without the technical characteristic described; do not repeat them here; certainly; described above is not to restriction of the present utility model; this utility model is also not limited to the example above; change that those skilled in the art are made in essential scope of the present utility model, retrofit, add or replace, also should belong to protection domain of the present utility model.
