Description
Technical field
The utility model relates to lithium bromide refrigerator technical field.
Background technology
Lithium bromide belongs to salt, is white crystals, soluble in water and alcohol, and nontoxic, stable chemical nature, undergoes no deterioration.Lithium-bromide absorption-type refrigerating machine is absorbent with lithium-bromide solution, take water as cold-producing medium, utilize water under a high vacuum evaporation endothermic reach the object of refrigeration.Can continuously go on for making process of refrigerastion, water as refrigerant steam after evaporation absorb by lithium-bromide solution, solution is thinning, this process occurs in absorber, then be power with heat energy, its moisture content is separated solution heating, and solution thickens, this process is carried out in generator.The steam obtained in generator condenses into water within the condenser, delivers in evaporimeter again and evaporate after throttling.Circulation like this reaches the object of continuous cooling.
Current lithium bromide refrigerator has a modal fault to be that lithium bromide crystalline polamer often occurs solution pump; unit is caused not run; need to shut down and crystallization is processed; and the method processing crystallization is by heating to the solution in pump from solution pump outer surface with steam; the time needed is long, and easily personnel scald.
Utility model content
Technical problem to be solved in the utility model is to provide the device preventing the crystallization of lithium-bromide solution pump in a kind of refrigeration unit; have in the non-stop-machine situation of refrigeration unit; lithium bromide heating crystals in solution pump is dissolved, ensures the feature of refrigeration unit continuous operation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: the device preventing the crystallization of lithium-bromide solution pump in a kind of refrigeration unit, comprises high pressure generator, low pressure generator, condenser, absorber, evaporimeter, cryogenic fluid pump, solution pump, high-temperature heat exchanger, solidifying water-to-water heat exchanger and low temperature heat exchanger; Pipeline by being equipped with solution pump between described low temperature heat exchanger and absorber is connected; Also comprise steam valve, branched pipe installed by the pipeline between described solution pump and absorber, described branched pipe is equipped with steam valve.
To the further improvement that the utility model does be: also comprise the first valve and the second valve; On the pipeline of described first valve installation between solution pump and low temperature heat exchanger, on the pipeline of described second valve installation between branched pipe and absorber.
The beneficial effect adopting technique scheme to produce is: when only opening steam valve during lithium bromide crystallization in solution pump, steam directly enters in solution pump, by lithium bromide dissolution of crystals, can ensure that unit is not shut down very soon.This device can also for the treatment of low temperature heat exchanger crystallization fault, can rapidly by dissolution of crystals.The utility model can reduce equipment failure rate, simplifies the maintenance operation time, enhances productivity.
