Abstract
The utility model discloses a device for recycling waste heat of steam condensate of a vacuum flash tank, and relates to the field of steam recycling devices in the ethyl acetate raw material production process. The device consists of a rectifying tower and vacuum flash tanks, wherein a waste liquid outlet is formed in the lower end of the rectifying tower; two flash tanks connected in series are provided; steam outlets and liquid outlets are formed in the vacuum flash tank; the steam outlets are connected with vacuum steam ejection pumps; the vacuum steam ejection pumps are connected with a steam condensate inlet of the rectifying tower through a pipeline; the liquid outlets are connected with a feeding preheater of the rectifying tower. The device is simple in structure and convenient to operate, the energy can be effectively utilized, the production cost is lowered, the water consumption is reduced, and meanwhile the burden of environment-friendly operation is alleviated, so that the device is particularly applied to production processes for producing ethyl acetate by using an esterification method.
Description
Technical field
The utility model relates to the steam recycling device field in the production procedure of ethyl acetate raw material, is mainly vacuum flasher steam condensed water waste heat retracting device.
Background technology
At the distillation process of ethyl acetate raw material, mash, when rectifying column carries out separation, enters environment friendly system after the waste liquid that produces is cooling at the bottom of rectifying column, causes following impact: 1, waste liquid will be used a large amount of power and waters in cooling process on producing; 2, waste liquid contained steam in the process of discharging is all wasted, and fails to make full use of energy.
Summary of the invention
Technical assignment of the present utility model is for not enough in above-mentioned technology, and a kind of vacuum flasher steam condensed water waste heat retracting device is provided.
The technical scheme that the utility model technical solution problem adopts is: vacuum flasher steam condensed water waste heat retracting device, by rectifying column and vacuum flasher, formed, wherein in described rectifying column lower end, be provided with waste liquid outlet, described vacuum flasher is two, series connection, vacuum flasher is provided with steam (vapor) outlet and liquid outlet, wherein said steam (vapor) outlet is connected with vacuum and steam jet pump, vacuum and steam jet pump is connected by pipeline with the steam-condensation water inlet of rectifying column, and liquid outlet is connected with rectifying column feed preheater.
The utility model is simple in structure, it is convenient to implement, by vacuum flasher, steam condensate (SC) can be divided into steam and liquid two parts, steam is used for heating the material in tower bottom of rectifying tower, and liquid carries out preheating to rectifying column feed preheater, therefore can effectively utilize the energy, reduce production costs, reduce again the consumption of water, also alleviated the load of environmental protection operation simultaneously, be specially adapted to esterification process and produce in the production technology of ethyl acetate.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
