Description
Technical field
The present invention relates to using waste heat from tail gas Absorption Refrigerator thermal source control technology field, particularly a kind of heat source control of using waste heat from tail gas used for absorbing refrigerator peculiar to vessel.
Background technology
Absorption refrigeration be a kind of be the refrigeration modes of power with heat energy.The high-temperature flue gas heat exchange of normally engine being discharged for the utilization of engine tail gas waste-heat is converted into the heat energy of steam and then the absorption refrigeration circulation of promotion refrigeration machine work system.For guaranteeing the refrigeration machine operate as normal, must stablize the suitable scope that remains on as the temperature of the steam of thermal source.At first, vapor (steam) temperature must reach the minimum operating temperature that the absorption refrigeration circulation requires, and in the common occasion of utilizing using waste heat from tail gas, this temperature value is looked different working condition and is about 100～120 ℃, and general engine tail gas waste-heat can reach.But the confidential stable operate as normal of absorption refrigeration and reach best refrigerating efficiency, vapor (steam) temperature should remain in the scope between 170～180 ℃ (pressing the different working conditions of refrigeration machine equally).Have unstability because the running of engine is the heat of using waste heat from tail gas, when heat is excessive, too much heat must be drained, vapor (steam) temperature just can be not too high, could guarantee the refrigeration machine operate as normal.Therefore, must control the waste heat of the motor exhaust that utilizes.
To the utilization of engine tail gas waste-heat, the mode that adopts is to make tail gas by tail gas heat exchanger water is heated into high-temperature steam at present.Described tail gas heat exchanger is the cylindrical shape tube shell type structure, its inner heat exchange tube bundle is parallel with the axis of cylinder shell and equidistantly arrange with annular, its bottom of tail gas heat exchanger is gas inlet, the top is the tail gas outlet, be respectively equipped with steam (vapor) outlet, condensate return entrance in tail gas heat exchanger top, bottom, described steam (vapor) outlet and condensate return entrance all are communicated with the shell side of tail gas heat exchanger.During work, tail gas is walked tube side, and water-steam is walked shell side, and cercoids feeds tail gas heat exchanger by gas inlet, by heat exchanger tube, drains from the tail gas outlet.
Control for the waste heat to the motor exhaust that utilizes, simpler and direct mode is the triple valve that is provided with control system at exhaust gas channel usually.During refrigeration machine work, triple valve is opened, and allows tail gas directly feed tail gas heat exchanger; When tail gas heat quantity too much made vapor (steam) temperature be higher than design temperature, the vapor (steam) temperature controller of refrigeration machine sent signal, and the triple valve action is drained tail gas from bypass pipe, do not make tail gas enter heat exchanger; When equipment needed heat (vapor (steam) temperature is lower than design temperature), temperature controller control triple valve moved again, and tail gas is introduced heat exchanger.So by the action of triple valve, realize the using waste heat from tail gas that utilizes is controlled.But; the open defect of this mode is: triple valve is under the environment of high-temperature tail gas (up to 400～600 ℃) always; valve plates usually is in the condition of high temperature and easy deformation; electric operator also damages easily under hot environment and can't normally use; just must shut down maintenance or change associated components this moment; when this phenomenon is relatively more serious, the refrigeration machine continuous operation will be safeguarded processing in ten days eight days, cause equipment shut-down, a large amount of consumptions of material and increasing of operating cost.And more serious problem is: because valve plates distortion and electrical components damage, cause that system's control was lost efficacy, executing agency moves malfunctioningly, cause equipment fault even have an accident.Special coldly in having turbo charged engine have when unusual, make exhaust temperature significantly rise (this situation is not rare), triple valve can not be closed the tail gas import of (or closing fully) heat exchanger immediately and motor exhaust is drained from bypass pipe, at this moment, a large amount of high-temperature flue gas pour in heat exchanger tube, and heat gathers rapidly, and vapor (steam) temperature is raise suddenly, pressure increases, and starts the steam discharge decompression until steam security valve; Or cross high temperature Steam Heating ammonia-aqueous solution, ammonia pressure raises, and starts spray ammonia until ammonia-water circulation system safety valve.The operate as normal and the safety in production that have had a strong impact on refrigeration machine equipment of this accident.
In addition, the installation of triple valve and bypass pipe takies very large space, and environment for use of (particularly middle-size and small-size fishing boat) is not suitable for especially very much to aboard ship for this.And, use the triple valve switch with the tail gas bypass or introduce heat exchanger and control the heat that refrigeration machine is provided, be not easy to accomplish to make steam control that refrigeration machine is provided in the operating temperature of the best from response speed and accuracy.And the solution of this problem wants the marine chillers institute that cube is little, in light weight, refrigerating efficiency is high in demand just.
