Abstract
The utility model discloses a kind of cold recovery system of the many warm areas of liquefied natural gas of van cooler, and provide a kind of liquefied natural gas vaporization that can utilize to discharge a large amount of cold energy to the cryogenic storage system of van cooler and refrigeration system cooling, to meet the cold energy of liquefied natural gas recovery system of power conservation requirement.The liquid natural gas outlet of liquefied natural gas fluid reservoir is connected with the entrance of filter with cryogenic freezing room heat exchanger by flow control valve, the outlet of cryogenic freezing room heat exchanger is connected with middle temperature reefer heat exchanger, high temperature reefer heat exchanger successively, and the outlet of high temperature reefer heat exchanger is connected with the import of driving engine.In this system, liquefied natural gas is three last inflow engines of heat exchange through basic, normal, high greenhouse successively, utilize the cold of liquefied natural gas vaporization respectively to reefer and cold chamber cooling, owing to additionally not needing fefrigerator, the low energy consumption of refrigeration system can be realized, reach energy-conservation object, improve cold energy organic efficiency, decrease energy dissipation.
Description
Technical field
The utility model relates to van cooler technical field, in particular, relates to a kind of many warm areas cold recovery system of liquefied natural gas of van cooler.
Background technology
Natural fuels is widely used as fuel because it has clean and efficient feature.For the ease of transport, often the natural fuels of gaseous state is carried out liquefaction process, form liquefied natural gas.Low-temperature liquefaction natural gas storage is under the low temperature of 110K.And liquefied natural gas needs vaporization in use, a large amount of cold energy will be discharged in vaporization to normality process.
At present, liquefied natural gas discharges a large amount of cold energy in vaporization and directly puts into surrounding environment or adopt once recovery cold energy method to normality process, and directly discharge is not recycled, and causes the waste of the energy.Adopt the method once reclaiming cold energy, although once reclaim, after once reclaiming, still have a large amount of cold energy directly to be put into surrounding environment, organic efficiency is not high.
Utility model content
The purpose of this utility model is the technological deficiency for existing in prior art, and provide a kind of liquefied natural gas vaporization that can utilize to discharge a large amount of cold energy to the cryogenic storage system of van cooler and refrigeration system cooling, to meet the cold energy of liquefied natural gas recovery system of power conservation requirement.
The technical scheme adopted for realizing the purpose of this utility model is:
A kind of many warm areas cold recovery system of liquefied natural gas of van cooler, comprise liquefied natural gas fluid reservoir, flow control valve, filter, high temperature reefer heat exchanger, middle temperature reefer heat exchanger, cryogenic freezing room heat exchanger, the liquid natural gas outlet of described liquefied natural gas fluid reservoir is connected with the entrance of filter with described cryogenic freezing room heat exchanger by described flow control valve, the outlet of described cryogenic freezing room heat exchanger successively with described middle temperature reefer heat exchanger, high temperature reefer heat exchanger connects, the outlet of described high temperature reefer heat exchanger is connected with the import of driving engine.
Compared with prior art, the beneficial effects of the utility model are:
In many warm areas cold recovery system of 1, the liquefied natural gas of van cooler of the present utility model, liquefied natural gas is three last inflow engines of heat exchange through basic, normal, high greenhouse successively, utilize the cold of liquefied natural gas vaporization respectively to reefer and cold chamber cooling, owing to additionally not needing fefrigerator, the low energy consumption of refrigeration system can be realized, reach energy-conservation object.Compared with a cold recovery system, this patent adopts many warm areas and repeatedly cold energy recovery method, improves cold energy organic efficiency, decreases energy dissipation.
2, many warm areas cold recovery cooling system of the present utility model is respond well, is conducive to food fresh keeping.

In figure: 1. liquefied natural gas storage tank, 2. flow control valve, 3. filter, 4. cryogenic freezing room heat exchanger, warm reefer heat exchanger, 6. high temperature reefer heat exchanger, 7. driving engine 5..
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The schematic diagram of many warm areas cold recovery system of the liquefied natural gas of the utility model van cooler as shown in Figure 1, comprise liquefied natural gas fluid reservoir 1, flow control valve 2, filter 3, high temperature reefer heat exchanger 6, middle temperature reefer heat exchanger 5, cryogenic freezing room heat exchanger 4, the liquid natural gas outlet of described liquefied natural gas fluid reservoir 1 is connected with the entrance of filter 3 with described cryogenic freezing room heat exchanger 4 by described flow control valve 2, the outlet of described cryogenic freezing room heat exchanger 4 successively with described middle temperature reefer heat exchanger 5, high temperature reefer heat exchanger 6 connects, the outlet of described high temperature reefer heat exchanger 6 is connected with the import of driving engine 7.
The liquid natural gas flowed out from liquefied natural gas fluid reservoir flows into flow control valve and filter successively, by flow regulating valve regulating flow, and by after metre filter, enter cryogenic freezing room heat exchanger, middle temperature reefer heat exchanger, high temperature reefer heat exchanger successively.Through too low middle hot room three last inflow engines of heat exchange.Because cold recovery device divides three kinds, low, neutralize high heat exchanger, form many warm areas reefer, reduce the possibility of frosting.
Cold energy of liquefied natural gas recovery system of the present utility model utilizes the cold of liquefied natural gas vaporization, respectively to reefer and cold chamber cooling, owing to additionally not needing fefrigerator, can realize the low energy consumption of refrigeration system, reach energy-conservation object.And a cold recovery system is compared, this patent adopts many warm areas and repeatedly cold energy recovery method, forms high, normal, basic three reefers, improves cold energy organic efficiency, decrease energy dissipation.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
