Description
Technical field
The energy-conservation use device of steam condensate in carbon five separators belongs to the pre-processing device field in carbon five separators, is specifically related to a kind of device that the middle pressure lime set of carbon five separators is carried out energy-efficient treatment.
Background technology
At present; The regional energy in the whole world is seriously in short supply; Energy-conservation has been that national governments and manufacturing enterprise pay much attention to the direction with Implementation Strategy; Especially China is at oil, metallurgy, chemical industry, and the large-scale centralized heating system, needs further to transform and perfect like the steam power system in industry such as community, machine-operated school, hotel and large-scale synthesis recreational facilities and the field.
Moreover energy consumption is an of paramount importance production target in the Chemical Manufacture, is the main aspect that cost control embodies, and therefore, energy-saving and cost-reducing is the main purpose and the direction of technological innovation, transformation.In carbon five separators, each unit process is distillation operation, and capital equipment is normal pressure, decompression and extractive distillation column, whole device have more than 20 reboiler with in the device that boils, the large usage quantity of steam.
At present, in the domestic same device, the steam condensate that the steam heat that provides for reboiler is produced after exchanging mainly passes through a surge tank buffering back and directly discharges, and the reasonably utilization once more of the repetition of being unrealized; Energy waste is more serious, and because pressure reduces and coagulate the reduction of water boiling point, the evaporation of vaporizing fast of the lime set in exit; The emptying amount is very big, and this process steam consumption is big, and energy consumption is higher; Accordingly, there is bigger potential safety hazard in this technology, wherein; A large amount of steam gets in the draining trench, and temperature is higher, as easy as rolling off a log hurting sb.'s feelings.
Summary of the invention
The technical problem that the utility model will solve is: overcome the deficiency of prior art, a kind of energy-conservation use device of realizing steam condensate in steam condensate second use, energy savings, safe and reliable carbon five separators is provided.
The utility model solves the technical scheme that its technical problem adopted: the energy-conservation use device of steam condensate in these carbon five separators; Comprise the low-pressure steam regulating tank and the heater that connect through pipeline; It is characterized in that: between low-pressure steam regulating tank and heater, connect a steam buffer jar through another pipeline; Steam buffer jar one end adjoin thermic devices, the other end is divided into three the tunnel, connects low-pressure steam regulating tank, circulating water pool and low-pressure steam pipe network respectively.Pretreatment unit through at carbon five separators increases a steam buffer jar, and middle pressure steam through after the flash distillation, is incorporated into the low-pressure steam that produces in the low-pressure steam pipe network, realizes the recycling of steam with this.
Described low-pressure steam regulating tank one upper lateral part connects low pressure steam line, and the bottom connects the middle pressure steam pipeline, and the bottom connects the steam buffer jar through another middle pressure steam pipeline.
Described heater comprises pressure-regulating valve, rectifying column reboiler and heat-exchanger pump.After pressure-regulating valve carries out the pressure adjusting, feed in the heater and conduct heat.
Compared with prior art, the beneficial effect that is had of the utility model is:
1, adopts new technology; Energy savings and resource, be lowered into the product cost: the steam of whole device is realized progressively step-down according to pressure, makes full use of; Steam condensate is also realized second use; According to per hour 1 ton of steam calculating, can practice thrift about 7200 tons of steam every year, can economize on the use of funds about 158.4 ten thousand yuan; Through experiment showed,, can practice thrift fresh supplemented water 21600m every year according to per hour 3 cubes of fresh waters calculating
3
2, both rationally recycled steam energy; Realize the cascade utilization of steam again, reduced a large amount of costs, and on this basis, improved the security in the production process; Have good economic benefit and operational reliability, have good promotion and application prospect.
