Abstract
An anti-blockage device in new pentanediol distillation process comprises an absorption cylinder 1 containing water and an absorption pipe 2 connected with the distillation equipment, wherein the absorption cylinder 1 is positioned with a cooling device and an outlet pipe 11 connected with a vacuum pump, and a cooling device thereof is positioned with a cooling water inlet pipe 1 and a cooling water outlet pipe 13. The absorption pipe 2 is positioned on the absorption cylinder 1, wherein the lower end of the absorption pipe 2 is inserted in the water in the absorption cylinder 1. To prevent the absorption pipe 2 from being blocked when the distilled products condense in entering the absorption cylinder 1, the absorption pipe 2 has a heating steam bushing 3 outside, wherein the heating steam bushing 3 is positioned with a heating steam inlet 31 and a condensate water outlet 32. The utility model shall be installed between the distillation equipment and the vacuum pump in operation. The utility model has the advantage of easy structure and operation, capable of continuous production, highly efficient in production, the service life of the vacuum pump being lengthened, the discharge of new pentanediol being lessened, with substantial economic and social benefit.
Description
Technical field:
The utility model relates to the solid vacuum distillation plant in a kind of chemical production equipment, antiplugging apparatus in particularly a kind of neopentyl glycol still-process.
Background technology:
In the existing neopentyl glycol distillation purification process, uncooled fully in order to prevent neopentyl glycol, adopted the way of multi-stage condensing.This method is not only invested bigger, and the pipeline of vacuum system very easily stops up, and causes to be difficult to operate continuously, and needing in the production often stops clears up condenser, the poor continuity of production.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and provide a kind of simple in structure, can keep serialization production, antiplugging apparatus in the high neopentyl glycol still-process of production efficiency.
The technical solution of the utility model is: antiplugging apparatus comprises absorption cylinder that water is housed and the absorption tube that is connected with distillation plant in the neopentyl glycol still-process, absorb on the cylinder outlet pipe that is connected with vacuum pump is arranged, absorption tube is installed in and absorbs on the cylinder, and insert in the water that absorbs in the cylinder its lower end.
The further technical scheme of the utility model is: stop up absorption tube for preventing the condensation when entering the absorption cylinder of distillatory product, the heating steam sleeve pipe is arranged outside absorption tube, more than the fusing point of distillage, heating steam import and condensation-water drain are arranged on the heating steam sleeve pipe with the temperature that keeps absorption tube.
The utility model further technical scheme is: absorbing on the cylinder has refrigerating unit, and entrance of cooling water pipe and cooling water outlet pipe are arranged on the refrigerating unit, and its temperature that can prevent to absorb cylinder rises too fast, thereby influences the vacuum tightness of Distallation systm.
The utility model compared with prior art, has following advantage owing to adopt as above design:
1, simple in structure, easy to operate, can keep serialization production;
2, production efficiency improves 50% on former basis, and prolong the work-ing life of vacuum pump greatly;
3, greatly reduce the discharging of neopentyl glycol tail gas, have good economic benefit and social benefit.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings: antiplugging apparatus comprises absorption cylinder 1 that water is housed and the absorption tube 2 that is connected with distillation plant in the neopentyl glycol still-process; Absorbing on the cylinder 1 has refrigerating unit and the outlet pipe 11 that is connected with vacuum pump, and entrance of cooling water pipe 12 and cooling water outlet pipe 13 are arranged on the refrigerating unit, and its temperature that can prevent to absorb cylinder 1 rises too fast, thereby influences the vacuum tightness of Distallation systm; Absorption tube 2 is installed in and absorbs on the cylinder 1, insert in the water that absorbs in the cylinder 1 its lower end, stop up absorption tube 2 for preventing the condensation when entering absorption cylinder 1 of distillatory product, heating steam sleeve pipe 3 is arranged outside absorption tube 2, more than the fusing point of distillage, heating steam import 31 and condensation-water drain 32 are arranged on the heating steam sleeve pipe 3 with the temperature that keeps absorption tube 2.During use the utility model is installed between distillation plant and the vacuum pump and gets final product.
