The acrolein absorbing tower removes crylic acid before acrolein is absorbed, and can prevent the acrolein from being polymerized due to the easy volatility and the easy polymerizability of the acrolein, thereby improving the efficiency of a device.
Description
Technical field
The utility model relates to a kind of methacrylaldehyde absorption tower, belongs to the chemical industry equipment field.
Background technology
Contain a large amount of acrylic acid in the reacting gas in the methacrylaldehyde production process, so before absorbing methacrylaldehyde, must earlier acrylic acid be removed.When adopting two tower process, reacting gas is earlier through acrylic acid absorption column, at the bottom of tower, obtain acrylic acid aqueous solution, absorb back gas and enter the methacrylaldehyde absorption tower through pipeline again, at the bottom of tower, obtain aqueous acrolein solution, because of the effumability of methacrylaldehyde and hypertoxicity, easily polymerizable, cause in the two tower process processes, polymerization easily takes place in methacrylaldehyde, thereby influences the yield of device, causes environmental hazard simultaneously.When adopting two tower process, acid is operated for dividing tower with aldehyde, and acid is difficult for grasping with aldehyde concentration, is not easy to obtain the acrylic acid and the acrolein solution of steady concentration, and subsequent treatment is had certain unstability.
Summary of the invention
According to the deficiencies in the prior art, the technical problems to be solved in the utility model is: a kind of methacrylaldehyde absorption tower is provided, makes methacrylaldehyde separate in same tower with acrylic acid and absorb.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of methacrylaldehyde absorption tower is provided, it is characterized in that by comprising the methacrylaldehyde absorber portion and washing the acid section, the methacrylaldehyde absorber portion is positioned at washes acid section top, wherein methacrylaldehyde absorber portion top offers exhaust port, install below the exhaust port and absorb water inlet, absorb the water inlet lower end methacrylaldehyde absorber portion filler is installed, be provided with the methacrylaldehyde section below the methacrylaldehyde absorber portion filler and rise gas hood, the methacrylaldehyde section rises the gas hood lower end and is provided with the acrolein solution outlet, acrolein solution outlet lower end is that methacrylaldehyde absorber portion bottommost is equipped with two sections and washes sour filler, topmost the acrylic acid section is installed rises gas hood to wash the acid section, the acrylic acid section rises to be provided with below the gas hood inhales the acid solution distributor, inhale acid solution distributor lower end and be equipped with and wash one section filler of acid, washing acid section bottom has air inlet and acid solution outlet and washes the acid section and link to each other.
The utility model is that original acrylic acid scrubbing tower and methacrylaldehyde absorption tower are merged into a tower, and a parts and function do not become in the tower, but can realize tower operation.
The beneficial effects of the utility model are: can earlier acrylic acid be removed before absorbing methacrylaldehyde, can be because of the effumability of methacrylaldehyde and hypertoxicity, easily polymerizable, cause methacrylaldehyde generation polymerization, thereby improved the yield of device, also can not cause environmental hazard simultaneously, realize that the whole absorption process operations elasticity in tower operation back strengthens greatly, has effect preferably to control acrylic acid concentration, methacrylaldehyde concentration.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 is exhaust port; 2 for absorbing water inlet; 3 is methacrylaldehyde absorber portion filler; 4 rise gas hood for the methacrylaldehyde section; 5 are the acrolein solution outlet; 6 are two sections washes sour filler; 7 rise gas hood for the acrylic acid section; 8 for inhaling the acid solution distributor; 9 for washing one section filler of acid; 10 is air inlet; 11 are the acid solution outlet.
The specific 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: exhaust port 1, absorb water inlet 2, methacrylaldehyde absorber portion filler 3, the methacrylaldehyde section rises gas hood 4, acrolein solution outlet 5, wash sour filler 6 for two sections, the acrylic acid section rises gas hood 7, inhale acid solution distributor 8, wash one section filler 9 of acid, air inlet 10 and acid solution outlet 11, the methacrylaldehyde absorption tower is mainly by the methacrylaldehyde absorber portion with wash acid section and constitute, the methacrylaldehyde absorber portion is positioned at washes acid section top, wherein methacrylaldehyde absorber portion top offers exhaust port 1, install below the exhaust port 1 and absorb water inlet 2, absorb water inlet 2 lower ends methacrylaldehyde absorber portion filler 3 is installed, be provided with the methacrylaldehyde section below the methacrylaldehyde absorber portion filler 3 and rise gas hood 4, the methacrylaldehyde section rises gas hood 4 lower ends and is provided with acrolein solution outlet 5, it is that methacrylaldehyde absorber portion bottommost is equipped with two sections and washes sour filler 6 that acrolein solution exports 5 lower ends, topmost the acrylic acid section is installed rises gas hood 7 to wash the acid section, the acrylic acid section rises to be provided with below the gas hood 7 inhales acid solution distributor 8, inhale acid solution distributor 8 lower ends and be equipped with and wash one section filler 9 of acid, washing acid section bottom has air inlet 10 and acid solution outlet 11 and washes the acid section and link to each other.
During use, reacting gas is entered the washing section of acrylic acid absorption column by air inlet 10, once through washing one section filler 9 of acid, inhale acid solution distributor 8, the acrylic acid section rises gas hood 7 and two sections wash sour filler 6, advanced the two-stage washing, and rise gas hood 4 place's temperature by control methacrylaldehyde section, make that methacrylaldehyde gas concentration and acrylic acid content reach a desired value in the gas.Rising gas hood 4 by the methacrylaldehyde section separates the acrylic acid absorber portion of aqueous acrolein solution and bottom.After washing mist after the acid and absorbing methacrylaldehyde through the aqueous solution, waste gas is discharged by top exhaust port 1, and water is entered by the absorption water inlet 2 of upper end, and the acid solution of Xing Chenging has acid solution outlet 11 discharges at last.
After this equipment came into operation, whole absorption process operations elasticity strengthened greatly, and control acrylic acid concentration, methacrylaldehyde concentration are had effect preferably.
