Description
Technical field
The utility model relates to a kind of refrigeration machine, relates in particular to the ammoniacal liquor absorption refrigerating machine generator peculiar to vessel that a kind of engine of boat and ship exhaust heat drives.
Background technology
The generator that has now had ammoniacal liquor absorption refrigeration unit to use, but also be in conceptual phase can be good at solving the anti-generator that jolts, tilts, waves, ammoniacal liquor absorption refrigerating machine generator peculiar to vessel in particular for a kind of engine of boat and ship exhaust heat driving, the problem of can solve inclination, jolt, waving does not have manufacturer production temporarily and sells.
Summary of the invention
The purpose of this utility model provides a kind of generator of ammoniacal liquor absorption refrigerating machine peculiar to vessel of suitable engine of boat and ship exhaust heat driving.
The purpose of this utility model is realized by following technical scheme, and a kind of heat exchanger tube is characterized in that being respectively arranged with pipe joint at the heat exchanger tube two ends.
A kind of ammoniacal liquor absorption refrigerating machine generator peculiar to vessel, it is characterized in that it is by heat exchanger tube, end socket, housing, the shell-and-tube generator that front smoke box and back smoke box are formed, form upper strata heat exchanger tube tube bank that is communicated with smoke exhaust pipe and the lower floor's heat exchanger tube tube bank that is communicated with engine exhaust port by many described heat exchanger tubes, every heat exchanger tube two ends in upper strata heat-exchanging tube bundle and the lower floor's heat-exchanging tube bundle are respectively arranged with the corrosionproof pipes joint.
Concrete characteristics of the present utility model also have: be provided with dividing plate in described front smoke box, described dividing plate is divided into upper strata heat exchanger tube tube bank that is communicated with smoke exhaust pipe and the lower floor's heat exchanger tube tube bank that is communicated with engine exhaust port to heat exchanger tube.Flue gas enters from the lower floor's heat exchanger tube tube bank that is communicated with engine exhaust port, restrains out from the upper strata heat exchanger tube.
Be respectively arranged with ammonia outlet in the generator center upper portion and the left and right sides, be provided with process duct in the generator bottom.
In the generator bottom concentrated solution liquid distributor is set, from NaOH solution tank NaOH and be distributed to enclosure interior through the concentrated solution that solution pump transports uniformly by the solution liquid distributor and heated by the high-temperature residual heat gas in the heat exchanger tube, adopt this measure to make, waste heat is fully utilized, saved the energy, this is one of advantage of absorption refrigeration.
The beneficial effects of the utility model are: every heat exchanger tube two ends all are welded with the pipe joint of the same model of certain-length, this purpose is in order to prevent the gas attack heat exchanger tube, because what walk in the heat exchanger tube is the high speed flue gas, the flue gas heat exchanger tube of flowing through is mainly exchanged the heat pipe import and export and is caused big corrosion phenomenon, at heat exchanger tube two ends welded stub connection, after treating that pipe joint is corroded, change pipe joint, avoided the corrosion of heat exchanger tube, this scheme has prolonged the service life of heat exchanger tube, has also prolonged the life-span of generator simultaneously.
Upper strata heat exchanger tube tube bank in the generator and lower floor's heat exchanger tube tube bank nature divide two flow processs up and down with the high-temperature residual heat gas of flowing through, enter earlier the heat exchanger tube tube bank of lower floor's flow process uniformly from the high-temperature gas of engine of boat and ship discharge, and then the heat exchanger tube that enters the upper strata flow process is uniformly restrained, discharge from smoke exhaust pipe at last, two flow processs have guaranteed that the concentrated solution in high-temperature residual heat gas and the housing carries out heat exchange fully, improved utilization rate of waste heat greatly, saved the energy, this is one of advantage of absorption refrigeration.The generator center upper portion and about an outlet respectively is set, the ammonia escape pipe is set on generator top, because concentrated ammonia solution can produce certain high pressure under the heating of the engine of boat and ship exhaust that has certain waste heat heat, gases at high pressure and liquid will outwards discharge by certain path, if the gas outlet can not influence the release of gas up, seriously cause the blast of container, therefore ammonia outlet is arranged at the top of generator, being convenient to ammonia enters into gas-liquid separator smoothly and carries out gas-liquid separation, ammonia outlet is set in addition last, can reach a stable ammonia generation pressure, can not cause a lasting high pressure, under a certain stable generation pressure, ammonia can constantly come out to keep the normal refrigeration of unit.The ammonia bubble is evaporated by waste heat in full hydroful liquid generator, is being mingled with liquid and is spraying from two side outlets, enters into gas-liquid separator, respectively puts an outlet about the while and can guarantee that the gas-liquid of discharging is evenly free in tilting, jolting, wave.Before dispatching from the factory, need to fill certain amount of ammonia water solution and test owing to consider unit, the tapping process duct is set in the generator bottom, and and need supply in the later maintenance or change ammonia spirit, therefore tapping technology valve is arranged at the generator bottom, under the effect of gravity, is convenient to fill and emit ammonia spirit.So setting can be the abundant time and the steric requirements of bringing of ammonia, makes it that circulation fully take place to participate in; Advantage of the present utility model has clearly guaranteed the work of engine exhaust-powered refrigerator under the condition that frequently tilts, waves, jolts; Have that energy-saving and environmental protection, operating cost are low, the characteristics of freedom from repairs; Be specially adapted to the ammoniacal liquor absorption refrigerating machine generator peculiar to vessel that a kind of engine of boat and ship exhaust heat of refrigeration, ice making and the air-conditioning of all kinds of boats and ships drives.
