Abstract
The invention relates to a discharge spout for polyvinyl chloride resin production, and belongs to the field of chemical machines. The discharge spout comprises a discharge spout body, and a mixer and an antifoaming device are arranged in the discharge spout body. Foam which contains unreacted vinyl chloride monomers, emulgator and the like and is generated in the chloroethylene recycling process is subjected to antifoaming treatment in a physical mode, meanwhile, vinyl chloride monomers in a gas phase and fine latex in the foam are recycled, and paste resin latex obtained after antifoaming can directly enter a receiving tank, and enters a drying procedure from the receiving tank. According to the discharge spout, a traditional antifoaming treatment method of adding a chemical antifoaming agent is replaced, and the advantages of being thorough in antifoaming, easy to operate, high in economic benefit and excellent in product quality, saving energy, reducing consumption and the like are achieved.
Description
technical field:
The present invention relates to chemical machinery field, be specifically related to a kind of blowpit for polyvinyl chloride resin production.
background technology:
In the technique of producing PVC paste resin, vinyl chloride is recycled to system in blowpit process can take the emulsifying agent and serum that foam includes out of.Therefore, in vinyl chloride removal 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 adds the chemical method of chemical defoamer to eliminate foam in vinyl chloride removal process, and 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 solve the problem, and a kind of blowpit for polyvinyl chloride resin production with physical defoaming device is provided.
The object of the invention is to be achieved through the following technical solutions: a kind of blowpit for polyvinyl chloride resin production, comprise blowpit body, described blowpit body is the horizontal vessel of tilting, blowpit body axis and horizontal angle are 3 ° ~ 10 °, discharge port is set at the low spot place of blowpit body simultaneously, mixer and dynamic defoaming machine is provided with in described blowpit body, described mixer is installed on the top of described discharge port, described mixer comprises shaft and paddle, described blowpit body lower part is fixed in shaft one end of described mixer, the paddle of described mixer is arranged on the latter half of described shaft, described dynamic defoaming machine is installed on the height point place of blowpit body upper part.
Preferably, described dynamic defoaming machine comprises transmission device and blade.
Preferably, described dynamic defoaming machine also has rinse mouth and VCM floss hole.
Preferably, the blade of described dynamic defoaming machine adopts fan split blade type oblique cone structure, and the angle of blade oblique cone is 12 ° ~ 45 °.
Preferably, the paddle of described mixer is provided with one or more.
Preferably, described dynamic defoaming machine and mixer adopt DCS to control.
Preferably, the blade of described blowpit body internal surface and/or mixer, shaft adopt polishing.
Compared with prior art, usefulness of the present invention is: by arranging mixer and dynamic defoaming machine in blowpit body, vinyl chloride serum coarse grain in removal process is made to carry out abundant wet-milling, and for physically defoaming treatment is carried out to the foam containing unreacted VCM, emulsifying agent, serum, thin colloid, initator produced in removal 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 dynamic defoaming machine blade schematic diagram.
In figure: 1, blowpit body, 2, dynamic defoaming machine, 3, transmission device, 4, blade, 5, mixer, 6, discharge port, 7, rinse mouth, 8, VCM floss hole, 9, shaft, 10, paddle.
detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of blowpit for polyvinyl chloride resin production according to Fig. 1 and Fig. 2, comprise blowpit body 1, described blowpit body 1 is the horizontal vessel of tilting, its axis and horizontal angle are 3 ° ~ 10 °, discharge port 6 is set at low spot place, installing dynamic defoaming machine 2 and mixer 5 in blowpit body 1 simultaneously; Described mixer 5 is installed on the top of described discharge port 6, described blowpit body 1 bottom is fixed in shaft 9 one end of described mixer 5, the paddle 10 of described mixer 5 is arranged on the latter half of described shaft 9, described dynamic defoaming machine 2 is installed on the height point place on described blowpit body 1 top, described dynamic defoaming machine 2 comprises transmission device 3 and blade 4, described dynamic defoaming machine 2 also has rinse mouth 7 and VCM floss hole 8, described blade 4 adopts fan split blade type oblique cone structure, and the angle of blade 4 oblique cone is 12 ° ~ 45 °.
Operationally, described transmission device 3 drives described blade 4 to rotate to described dynamic defoaming machine 2, and described blade 4 forms one downward wind-force after rotating around it.When the foam that gas-phase space in container 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 destroy foam, and when foam generation is larger, lather quickness compares faster time, foam rises to described blade 4 place and just can be broken up by the blade 4 in High Rotation Speed, and the vinyl chloride gas of gas-phase space can export from VCM floss hole 8.After froth breaking end-of-job, open rinse mouth 7, blade 4 is rinsed.
Another preferred embodiment, difference is that the paddle 10 of described mixer 5 is provided with one or more.
Another preferred embodiment, difference is that described dynamic defoaming machine 2 and mixer 5 adopt DCS to control.
