The utility model is the esterification steam waste heat recovery through polyester device, becomes high-quality thermal source through carrying out heat exchange, and it is required that this thermal source is offered the long or short filament explained hereafter.This system does not influence under the prerequisite of original polyester production process in assurance, has utilized the waste heat of esterification steam fully, has saved the energy greatly, has appreciable economic benefit and social benefit.
The technical scheme of the utility model:
The low pressure water vapor that utilizes process tower to produce hangs down the Sweden of the temperature difference and the PHE interchanger of German import and the Japanese Yokogawa CS3000 DCS system that matches through the advanced person LP steam waste heat is recycled use in road, back long or short filament is produced fully.
The technical characterstic of the utility model:
Pump is inhaled effect: utilize water at low temperature to be unit head, reclaim exhaust steam heat energy and condensed water, the recovery 100%.
Heat transfer characteristic: exhaust steam directly mixes with operating water carries out heat exchange, and under the shock wave effect of two phase flow heat transfer, the hot water of output does not have cavitation phenomenons, scaling not, and heat exchange efficiency is sustainable to remain on 100%.
Starting characteristic: start-up operation is simple and safe, and hot-water supply immediately after starting.
Serviceability: movement-less part, do not have and leak, stable, safe and reliable.Major parts adopts stainless material to make, and can non-maintaining operation reach more than 10 years.
Floor space is little: volume is little, and flexible arrangement can be practiced thrift a large amount of initial costs.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
