Abstract
The utility model discloses a novel saponification tower device and relates to equipment for chemical production; the novel saponification tower device comprises a tower body, a tower plate, a flushing water pipe and a steam coiled tube, the tower plate is fixed in the tower body, the arc flushing water pipe is arranged on the tower plate, the steam coiled tube is arranged at the lower part in the tower body, the tower plate is a double-overflowing tower plate and is provided with an overflow weir, and a downcomer is arranged close to the position of the tower wall. The novel saponification tower device has high production capacity, low pressure drop of the tower plate, high efficiency, strong anti-blocking and anti-scaling capacity.
Description
Technical field
The utility model relates to a kind of Chemical Manufacture device therefor, a kind of saponification column device that is used to produce expoxy propane of saying so more specifically.
Background technology
At present, the mode of big in the world rule film suitability for industrialized production expoxy propane mainly contains two kinds: be the chlorohydrination of representative and be the indirect oxidation method of representative with U.S. ARCO chemical company with U.S. DOW chemical company.China begins to produce expoxy propane the sixties, most of chlorohydrination that adopts.Wherein the saponifying process capital equipment is a saponification column, has determined the propylene consumption of expoxy propane and stablizing of steam consumption and production.The development that the favourable chlorohydrination of the technology innovation of saponification column is produced expoxy propane.
The common fault of saponification column mostly is that plate efficiency is general at present, and operating flexibility is little, and fouling is stopped up easily.Novel saponification column device described in the utility model has particular design, and production capacity is big, the plate efficiency height, and operating flexibility is big, and plate pressure drop is little, and is simple in structure, and anti-clogging fouling ability is strong.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of production capacity big, and plate pressure drop is little, efficient is high, the novel saponification column device that anti-clogging fouling ability is strong.
The purpose of this utility model is to be achieved by following technical scheme:
A kind of novel saponification column device comprises tower body, column plate, and wash tub pipe, steam pipe coil is characterized in that, and column plate is fixed in the tower body, and column plate is provided with the arc wash tub pipe, and the bottom is provided with steam pipe coil in the tower body, and described column plate is the double overflow column plate and is provided with downflow weir.
Described column plate is provided with downspout at the Kao Tabi place.
Described column plate has eight layers, and wherein 5,6,7 layers of column plate are provided with exit weir.
Horizontal column plate is housed in the tower body of circle, arrange according to certain tray spacing, the sieve aperture that has on the column plate, downflow weir is set on the column plate, be to keep certain thickness liquid layer on the plate, every layer of column plate is provided with downspout at the Kao Tabi place, between downspout bottom and the lower floor's column plate certain space arranged, and helps dropping liq and flows to lower floor's column plate through this.During operation, liquid flow to lower floor's column plate by the upper strata column plate through downspout by the gravity effect, and cross-current crosses column plate to another downspout, and so step by step tray is dirty, is gone out by tower bottom flow at last, and the downflow weir on the column plate can make and keep certain thickness mobile liquid layer on the plate face; Uprising gas is delivered at the bottom of the tower below the undermost column plate, promote by pressure difference, be dispersed into tiny stream thigh by sieve aperture, liquid layer bubbling and going out onboard, gas-liquid contacts closely and carries out mass transfer, under normal operating gas velocity, air-flow by the sieve aperture rising, should be able to stop liquid to be revealed through sieve aperture downwards, every layer of column plate is provided with wash tub pipe, can prevent effectively that lime mud in the saponification process from stopping up crack at the bottom of downspout and the downspout.
The beneficial effects of the utility model are:
1. production capacity is big; 2. plate efficiency height; 3. operating flexibility is big; 4. plate pressure drop is little; 5. anti-clogging fouling ability is strong.
Description of drawings
Fig. 1 is the structural representation of the utility model saponification column device.
Among the figure: 1. sieve plate column plate; 2. downspout; 3. wash tub pipe; 4. exit weir; 5. steam pipe coil; 6. tower body.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing:
In the drawings, in diameter is the circular tower body 6 of 5m 8 layers of horizontal column plate are housed, column plate 1 spacing is 900mm; Have the sieve aperture of φ 20～25mm on the column plate 1, sieve aperture is made triangular and is arranged 1-4 layer percent opening 6.40% sieve aperture φ 20 on column plate 1, centre-to-centre spacing 61mm, 5,6 layers of percent opening 10.00% sieve aperture φ 25, centre-to-centre spacing 61mm, 7,8 layers of percent opening 18.43% sieve aperture φ 25, centre-to-centre spacing 43mm; It is flat type double overflow weir that the downflow weir form is set on the column plate 1, and height of weir plate is 100mm; Every layer of column plate 1 is provided with downspout 2 at the Kao Tabi place, and the center downcomer width is 436mm, and both sides downspout width is 543mm, between the bottom of downspout 2 and the lower floor's column plate certain space arranged, and highly is 76.2mm; 5,6,7 layers of column plate is provided with the exit weir 4 of the 30 ° of high 80mm in inclination angle; Steam inside coil pipe 5 circular diameters are 4000mm, and the coil pipe caliber is φ 150 perforate φ 5 totally 766 holes; Column plate 1 wash tub pipe 3 is an arc, arranges that along tower body 6 inwalls the downward 30 ° of hole for water sprayings that have 10～20 φ 10 of level can be flushed to the lime mud at place, crack at the bottom of downspout and the downspout.
