Abstract
The invention relates to the field of chemical machinery, and relates to a removing tower used in polyvinyl chloride resin production. The removing tower comprises a tower body, a feeding port and a discharge port. A dynamic defoaming machine is arranged on the top of the tower. A feeding nozzle is arranged on the output end of the feeding port. A distribution pipe with an inwardly extending structure is arranged above the feeding nozzle. A plurality of spraying holes are provided on the distribution pipe. According to the invention, a traditional defoaming treatment method of adding a chemical defoaming agent is replaced. The removing tower is energy-saving and consumption-reducing, and has the advantages of thorough defoaming, simple operation, high economic benefit, good product quality, and the like.
Description
technical field:
The present invention relates to chemical machinery field, be specifically related to a kind ofly remove tower for polyvinyl chloride resin production.
background technology:
In the technique of producing PVC paste resin, polyvinyl chloride latex exports to enter through double pipe heater from blowpit and removes tower process, gas-phase space can produce a large amount of foams, containing unreacted VCM, emulsifying agent, serum, thin colloid, initator etc. in these foams, if these foams follow latex access arrangement pipeline, will blocking pipeline, what impact was produced normally carries out.In order to address this problem, traditional handicraft be add defoamer chemical method to eliminate foam, not only cost is higher, also directly affects the stability of latex and the performance of product.
summary of the invention:
The object of the invention is to enter to solve polyvinyl chloride latex the problem removing and produce a large amount of foam in tower process, and provide a kind of can ditch by mechanical means, deaeration carried out to the foam produced in subtractive process remove tower.
The object of the invention is to be achieved through the following technical solutions: thisly remove tower for polyvinyl chloride resin production, comprise tower body, charging aperture and discharging opening, it is characterized in that: described tower body top is provided with dynamic defoaming machine, described charging aperture output is provided with the feed nozzle that has constant slope, stretch the distributor pipe of structure in described feed nozzle top is provided with, described distributor pipe has several spray apertures.
Further, described dynamic defoaming machine comprises transmission device and impeller, and described impeller is provided with blade.
Further, described dynamic defoaming machine is also provided with rinse mouth and VCM floss hole.
Preferably, on described dynamic defoaming machine, the blade of impeller adopts fan split blade type oblique cone structure, and the angle of blade oblique cone is 12 ° ~ 45 °.
Preferably, described tower body inside is also provided with one or more layers of de-bubble dish.
Preferred, described de-bubble dish is made up of one or more metallic plate, and de-bubble dish has certain gradient, and edge is provided with several wedge angles triangular sawtooth outwardly.
Preferably, described charging aperture has one or more.
Preferably, remove tower described in and be provided with DCS control system.
Preferably, described tower body inner surface or blade, distributor pipe adopt polishing.
Compared with prior art, usefulness of the present invention is: by arranging feed nozzle at charging aperture place, and for physically defoaming treatment is carried out to the foam containing emulsifying agent, serum produced in subtractive process, reclaim the VCM in gas phase and the thin latex in foam simultaneously, paste resin emulsion bubbles hardly after froth breaking, directly can enter groove, and enter drying process by groove.Therefore, the present invention has and does not add the advantages such as chemical defoamer, froth breaking is thorough, simple to operate, energy-saving and cost-reducing, high financial profit, product quality are excellent.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the front view of dynamic defoaming machine impeller.
Fig. 3 is the top view of de-bubble dish.
In figure: 1, tower body, 2, dynamic defoaming machine, 201, transmission device, 202, impeller, 203, rinse mouth, 204, VCM floss hole, 205, blade, 3, charging aperture, 4, feed nozzle, 5, distributor pipe, 6, discharging opening, 7, de-bubble dish.
detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of according to Fig. 1 removes tower for polyvinyl chloride resin production, comprise tower body 1, charging aperture 3 and discharging opening 6, described tower body 1 top is provided with dynamic defoaming machine 2, described dynamic defoaming machine 2 comprises transmission device 201, impeller 202, rinse mouth 203 and VCM floss hole 204, it is inner that described impeller 202 stretches into tower body 1, and described rinse mouth 203 and VCM floss hole 204 communicate with tower body 1 inside; Described charging aperture 3 output is provided with the feed nozzle 4 that has constant slope, stretches the distributor pipe 5 of structure, described distributor pipe 5 has several spray apertures in described feed nozzle 4 top is provided with, and it is inner that described distributor pipe 5 is laterally fixedly connected on tower body 1.
Operationally, described transmission device 201 drives described impeller 202 to rotate to described dynamic defoaming machine 2, and described impeller 202 forms one downward wind-force after rotating around it.When the foam that gas-phase space in tower produces rises gradually, under normal circumstances, due to the reason of blast, the generation of foam can be suppressed and suppress foam to rise, and then destruction foam, and when foam generation is larger, lather quickness compares faster time, foam rises to described impeller 202 place and just can be broken up by the blade 205 in High Rotation Speed, and the vinyl chloride gas of gas-phase space can export from VCM floss hole 204.After froth breaking end-of-job, open rinse mouth 203, impeller 202 is rinsed.
Another preferred embodiment, difference is: as shown in Figure 2, and the blade 205 of described dynamic defoaming machine 2 adopts fan split blade type oblique cone structure, and the angle of blade oblique cone is 12 ° ~ 45 °.
Another preferred embodiment, difference is: as shown in Figure 3, and described tower body 1 inside is also provided with one or more layers of de-bubble dish 7, and described de-bubble dish 7 is fixedly connected with tower body 1 inwall.
Another preferred embodiment, difference is that described charging aperture has one or more.
Another preferred embodiment, removes tower and adopts DCS to control described in difference is.
