Description
Technical field
The utility model relates to a kind of therrmodynamic system, refers more particularly to the therrmodynamic system of a kind of oil storage enterprise accumulating oil product heat tracing.
Background technology
Because characteristics such as the high condensation point of oil storage enterprise accumulating oil product, high viscosity, the oil product ratio that needs to be incubated in crude oil stores presents increasing trend, this just needs to consume a large amount of Steam Heating keeping corresponding storage safe temperature, so the therrmodynamic system of oil tank becomes the main energy consumption facility in reservoir area.
Referring to shown in Figure 1, provide the schematic diagram of the oil storage enterprise boiler room therrmodynamic system of steam for oneself for present great majority, this system mainly comprises by pipeline connection water treatment system 1 together, insulation softened water tank 2, thermal deaerator 3, boiler 4, oil tank 5 and waste water tank 6, its course of work is as follows: the running water of room temperature is through the sedimentation in the water treatment system 1, filter, devices such as counter-infiltration become soft water and leave in the insulation softened water tank 2 as the make-up water of boiler, situation of change according to boiler load, boiler feedwater is aspirated into thermal deaerator 3 by water pump, the effect of thermal deaerator 3 is: utilize that boiler produces steam remove dissolved oxygen and other gas in the therrmodynamic system feedwater, prevent the corrosion of heat power equipment, promote simultaneously about the temperature to 104 ℃ of supplementing water, the high-temperature steam that utilizes boiler to produce under the pressure-fired environment of thermal deaerator 3 is warming up to 104 ℃, enter boiler 4 then, boiler 4 combustion fuel oil, water is heated into 178 ℃ steam, a high-temperature steam part enters thermal deaerator 3 by inferior steam pipework 13, another part outputs to the insulation that is used for oil tank 5 and petroleum pipeline outside the boiler room by major steam line 12, the condensed water of the formation behind the steam insulation directly is discharged in the environment, the platoon water of the generation of boiler 4 in combustion process directly discharging advances waste water tank 6, handles being disposed in the environment through adding medicine.
At present, there is following problem in the above-mentioned therrmodynamic system that adopts: 1, because steam is to whole reservoir area heat tracing, because the reservoir area area is big, steam pipe system is long and complicated, therefore can't reclaim whole condensed waters, and the water yield of single condensed water discharging place relatively seldom.In addition, because the operation characteristic of oil storage enterprise, its use Steam Heating of tank body at certain specific storage oil product is not what continue, but discontinuity, be that the oil product temperature stops heating when arriving a certain particular value, and be lower than a certain particular value is to begin heating, therefore cause in the steam pipe line in the oil tank and stockpile condensed water, and because pipeline is a carbon steel material, therefore be easy to make and contain iron rust in the condensed water, while is owing to a jar interior steam pipe line directly contacts with oil product, so there is the possibility of oil-containing in condensed water.Owing to condensed water wide, the reason such as water quality is relatively poor that distributes, and water price is relatively low at present as can be seen from above 2, and general similar enterprise takes directly to discharge the way of condensed water, causes the waste of water resource.2, the thermal source that is used to heat make-up water in the thermal deaerator is the steam that the boiler combustion oil product produces, and mode of heating is contact, and it is not high to have wasted the valuable steam resource and the thermal efficiency.The quantity of steam of thermal deaerator consumption accounts for the proportion of boiler gas production between 10%～15%, promotes the make-up water water temperature that enters oxygen-eliminating device, reduces the oxygen-eliminating device steam economy, will bring more considerable energy-saving benefit.3, boiler platoon water is a kind of high-temperature high pressure water that contains certain alkalescence, and the water yield generally is directly to handle the back discharging at present continuously still seldom, has caused the waste of heat energy.
To sum up analyze, because existing therrmodynamic system can't be utilized the most low heat value energy and the water yield, therrmodynamic system overall thermal efficient is low, has caused the waste of a large amount of energy consumption and water resource.
