When stopped, the lithium bromide absorption type refrigerator can be used for filtering the lithium bromide solution in the refrigerator; the lithium bromide absorption type refrigerator can be used for the energy-saving refrigeration equipment in enterprises, guesthouses.
Description
The utility model belongs to a kind of refrigeration plant, particularly relates to a kind of profit and uses water as the lithium-bromide absorption-type refrigerating machine that cold-producing medium, lithium-bromide solution are made absorbent.
At present, generally use in the factory and enterprise with water vapour as power, be cold-producing medium, lithium-bromide solution refrigeration machine as absorbent with water, when lithium-bromide solution circulation time in refrigerator body, can produce stronger corrosion to metallic conduit such as the carbon steel of refrigeration machine, red copper or cavity, for preventing this corrosion, adopt the method that bromizates lithium solution line high vacuum and in lithium-bromide solution, add corrosion inhibiter usually.Because refrigeration machine can not guarantee absolute vacuum in actual the use, employed steam temperature is between 143 degree Celsius are spent to 174, for preventing the added corrosion inhibiter of corrosion---then corrosion inhibition decline when temperature is spent above Celsius 140 of lithium chromate, so lithium-bromide solution still has to a certain degree corrosion to pipeline and cavity, the result of corrosiveness produces Fe(OH)
3, Cu(OH)
2Fe
3O
4Deng insoluble matter, Fe(OH wherein)
3It is a kind of loose matter, it is attached to metallic surface, make corrosion inhibiter the metal surface to make membrane interaction not obvious, although the result drops into a large amount of corrosion inhibiter, and lithium-bromide solution still can continue corrosion to the metal surface by the loose iron oxide of infiltrate, the insoluble matter that corrosion produces flows in the refrigeration machine pipeline with lithium-bromide solution, prolongation along with service time, insoluble matter is cumulative, and dead angle place gathers or attached on the duct wall in refrigeration machine, consequently: (1) resistance of heat transfer increases, and influences heat exchange, makes refrigerating amount attenuation; (2) blocking pipe or nozzle make the refrigeration machine can't operate as normal even scrap; (3) insoluble matter flows in pipeline with liquid, makes the mechanical wear of pipeline and pump bigger, reduces service life; (4) influence corrosion inhibiter and make film, both increased the use amount of corrosion inhibiter, quickened Corrosion of Pipeline again in the metal surface.This refrigeration machine can't resemble common mechanical can take reparation apart, and its consequence must be that a refrigeration machine that is worth hundreds thousand of units is scrapped.So; the impurity that removal is suspended in the solution is crucial; the method that solution is filtered is at present: shut down lithium-bromide solution is entered receiver; filter with common filter paper then; all solution are filtered one time generally need 2～3 day time; certainly will influence production and refrigeration machine is out of service, can only carry out in not busy season (for example winter) so solution filters.After a duty cycle (being generally 6 months); the turbidity of solution is very big; because solution is discharged under stopped status naturally; suspension in the machine can't be discharged owing to precipitate; add refrigerating device inner pipeline complexity; solution is difficult to drain, and can mix with sediment and the residual liquid in the machine in the time of in the clear solution implanter after filtering, and bromizates lithium solution muddiness once more.
