Abstract
The utility model relates to an acrylic acid quench tower and belongs to the field of chemical equipment. The acrylic acid quench tower comprises a tower body, a tower cooler, a tower pump, and spray heads, wherein a cooling water inlet is formed in the upper end of the tower body; a flow-through plate is arranged at the lower end of the cooling water inlet; the bottom of the tower body is provided with a discharge port; and the discharge port is sequentially connected with the tower pump, the tower cooler, and the spray heads which are arranged on the lower part of the tower body through pipelines. The acrylic acid quench tower is characterized by also comprising an intratower liquid collection tank, an intratower cooler and an intratower circulating pump, wherein the middle part of the tower body is provided with the intratower liquid collection tank; and the intratower liquid collection tank is sequentially connected with the intratower circulating pump, the intratower cooler, and the spray heads which are arranged on the intratower liquid collection tank through pipelines. By the arranged upper, middle and lower three-layer cooling circulation system, the absorption effect of acrylic acid is also improved, so that the recovery rate of the acrylic acid is inevitably improved, the waste of the acrylic acid is reduced, materials are saved, the production cost of products is reduced, and the market competitiveness of the products is improved; and meanwhile, the equipment has a simple structure, and is convenient to repair and maintain.
Description
Technical field
The utility model relates to a kind of acrylic acid quench tower, belongs to the chemical industry equipment field.
Background technology
In acrylic acid is produced, when propylene, airborne oxygen carry out catalytic oxidation through oxidation catalyst, obtain the target product acrylic acid of gaseous state, except that target product, also have part accessory substance such as acetate, methacrylaldehyde, furfural, maleic anhydride, water etc.Because acrylic acid is prone to polymerization, need propylene steam acid chilling be absorbed, to prevent acroleic acid polymerization.Cheap and strong to acrylic acid absorbability because of the water price lattice, the chilling absorbent major part of acrylic acid quench tower is a water, but the more meeting that water adds causes acrylic acid concentration to reduce, and increases acrylic acid refined unit difficulty, increases energy consumption; And the cat head that can cause at least that water adds is discharged acrylic acid content height in the gas, causes the waste of acrylic products, and consumption is increased.
Summary of the invention
Deficiency according to prior art; The technical problem that the utility model will solve is: a kind of acrylic acid quench tower is provided; Not increasing under the situation that adds chilled water (chw), improve acrylic acid absorption efficiency through the structure that changes the acrylic acid quench tower, reduce acrylic acid waste; Practice thrift material, reduce production costs.
The utility model solves the technical scheme that its technical problem adopted: a kind of acrylic acid quench tower is provided; Comprise tower body, tower still cooler, tower still pump, shower nozzle; The tower body upper end is provided with the cooling water inlet, and the lower end, cooling water inlet is provided with turbogrid tray, and the tower body bottom is provided with discharging opening; Discharging opening connects tower still pump, tower still cooler successively through pipeline and is arranged on the shower nozzle of tower body bottom; Its characteristic is also comprising: circulating pump in cooler and the tower in collecting tank, the tower in the tower, and the tower body middle part is provided with collecting tank in the tower, and collecting tank connects in circulating pump in the tower, the tower cooler successively and is arranged on the shower nozzle above the collecting tank in the tower through pipeline in the tower.
Collecting tank is provided with liquid level gauge in the described tower.
Circulating pump is that two parallel connections are used in the described tower.
Reaction back products obtained therefrom is transported to next unit through tower still pump and pipeline.
The beneficial effect of the utility model is: use the upper, middle and lower-ranking cooling recirculation system through being provided with, make that acrylic acid quench tower cooling effect is better, acrylic acid assimilation effect also is improved; So just must improve acrylic acid rate of recovery, reduce acrylic acid waste, practice thrift material; Reduced production cost of products; Improved the competitiveness of product in market, this device structure is simple simultaneously, is convenient to maintenance and maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model;
1 is tower body among the figure; 2 is tower still cooler; 3 is tower still pump; 4 is collecting tank; 5 is shower nozzle; 6 is turbogrid tray; 7 is the cooling water inlet; 8 is cooler in the tower; 9 is circulating pump in the tower; 10 is liquid level gauge.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1; The utility model comprises: comprise tower body 1, tower still cooler 2, tower still pump 3, shower nozzle 5; Tower body 1 upper end is provided with cooling water inlet 7, and 7 lower ends, cooling water inlet are provided with turbogrid tray 6, and tower body 1 bottom is provided with discharging opening; Discharging opening connects tower still pump 3, tower still cooler 2 successively through pipeline and is arranged on the shower nozzle 5 of tower body 1 bottom; Its characteristic is also comprising: circulating pump 9 in cooler 8 and the tower in collecting tank 4, the tower in the tower, and tower body 1 middle part is provided with collecting tank 4 in the tower, and collecting tank 4 connects in the tower in circulating pump 9, the tower cooler 8 successively and is arranged on the shower nozzle 5 above the collecting tank 4 in the tower through pipeline in the tower.
Collecting tank 4 is provided with liquid level gauge 10 in the tower.
Circulating pump 9 is 2 parallel connection uses with tower still pump equal 3 in the tower.
Such setting just makes to have formed the upper, middle and lower-ranking circulating cooling system in the tower body 1 that make that acrylic acid quench tower cooling effect is better, acrylic acid assimilation effect also is improved, and has improved acrylic acid rate of recovery.
Reaction back products obtained therefrom is transported to next unit through tower still pump 3 and pipeline.
