Below in conjunction with the accompanying drawings mode of operation of the present utility model is described in detail:
This utility model has night and two kinds of working methods on daytime
One) work at night mode:
Mode of working at night includes that again refrigerating part and hydrate prepare two relatively independent parts of part, therefore again can be by
Principle of working at night is split as above-mentioned two parts and introduces respectively:
Refrigerating part:
Now, native system uses Absorption Cooling System, and working medium is to using solvent DMF and refrigerant R134a, at generator
In 15, utilize heater 16 that the DMF saturated solution dissolved with R134a is heated, after being heated, the R134a steaming that boiling point is relatively low
Issuing, gas rises through packing layer II 17 and assembles in generator 15 top, after heating a period of time, along with R134a steam
The increase of amount, the pressure of generator 15 reaches about 1mpa, and the pressure-control valve 19 being positioned at generator 15 top is backed down,
R134a high temperature and high pressure steam is after check (non-return) valve, stop valve enter condenser 21, with cross-ventilation heat exchange, at condenser 21 end
Section coil pipe, R134a has become highly pressurised liquid, and a portion will be stored in fluctuation-type reservoir 20, and another part then passes through
Stop valve regulates pressure flow through heating power expansion valve 22, and the R134a liquid of low pressure enters evaporator coil 24 and evaporates, this vaporizer
Coil pipe 24 is positioned at hydrate reaction bucket 1, provides cold for hydrate reaction of formation.After evaporation, the R134a steam of low-pressure low-temperature
In taking away bucket, heat enters absorber 7, and in absorber 7, R134a steam enters in bottom through refrigerant holes pipe 11, DMF solvent
Being sprayed by upper solvent spray nozzle 8, steam rises, and solvent falls, and both converge in packing layer I in the middle part of absorber 7, packing layer
Be embedded with in I 9 be connected with cooling water heat exchange coil 10, with take away R134a steam be dissolved in DMF solvent produce heat, promote inhale
The generation of receipts process.The pressure of absorber 7 is similar to evaporator coil 24, about 0.3mpa, and the pressure of generator 15 is big
About 1mpa, so the saturated solution bottom absorber 7 needs to increase pressure could enter generator 15, therefore selects solution pump 12 to add
Pressure, then solution carries out heat exchange entrance generator 15 through heat exchanger 14 with from the DMF solvent that the temperature of generator 15 is higher, for
Improving luminous efficiency and reduce DMF solvent evaporation, using the mode that sprays as shown in the figure, spray to use nozzle, nozzle is placed in generation
Between the two-layer filler of device 15 top；
Hydrate prepares part
When the pressure of hydrate reaction bucket 1 is less than 0.4mpa, it is positioned at the temperature and pressure sensor 25 at hydrate reaction bucket 1 top
Receiving pressure signal, the stop valve controlling to be installed on bye-pass IV 26 is opened, and the R134a steam of High Temperature High Pressure sprays through cold-producing medium
Mouth 23 enters water from reaction container bottom, and steam can relatively evenly enter in water, and beneficially hydrate generates.Steam is made at buoyancy
Using lower rising, with the cold water heat exchange of surrounding in uphill process, R134a molecular kinetic energy constantly reduces, and steam is progressively changed by gaseous state
For liquid, under hypersaturated state, be combined generation refrigerant gas hydrate with cold water around.The most direct with high steam state
Being passed through the R134a of reaction container after around cold water is condensed into liquid, small part directly participates in generating hydrate, due to R134a liquid
Body is more than the density of water, so major part R134a liquid sinks converges at bottom reaction container.For improving the generation effect of hydrate
Rate, processes two holes bottom this design reaction container, short-range missile skirt 27 is installed in a hole, and long guide wire 28, design are installed in another hole
As it can be seen, long guide wire 28 draws the cold water on top, short-range missile skirt 27 draws the R134a liquid of bottom, and both draw reaction container, warp
Canned motor pump 6 is admixed, and is passed through the blended spray nozzle in reaction container top 2 and sprays, and both mix substantially uniform, beneficially the life of hydrate
Become.The general pressure requirements of generation of hydrate is 0.4mpa, and temperature controls at about 0 DEG C.Pressure is by being passed through reaction container
R134a high steam ensure, temperature by the evaporator coil 24 being placed in reaction container by controlling with ambient water heat exchange.Reaction
Bucket top is provided with temperature and pressure sensor 25, receives temperature and pressure signal in reaction container, controls refrigeration system heating plant and arm respectively
The start and stop of the stop valve on road IV 26.Heating heat exchanger 3 only serves the effect of insurance, anti-in order to prevent too much vapours from entering
Ying Tong, condenses into liquid deposition bottom reaction container, and does not participate in hydration reaction.Liquid level raise certain altitude or, pressure
In the case of excessive temperature is low, heater will be opened.
Two) work by day mode
Work by day is to be melted by the hydrate prepared night to provide cold.Now, by controller control, bottom reaction container
Long guide wire 28 on stop valve and be provided with heating heat exchanger 3 bye-pass I stop valve close, connect have fan coil
The stop valve of the bye-pass II 30 of 4 is opened.Owing to the ice content in reaction container is about 50%, and hydrate crystal is the softest,
Density is the highest, and canned motor pump 6 extracts chilled water bottom reaction container, introduces the fan coil 4 in room, after heat exchange, from reaction container
The blended spray nozzle in top sprays in reaction container.In hydrate melting process, in reaction container, pressure is relatively low, discharges R134a
Gas is assembled in reaction container top, and in bucket, pressure gradually rises, and affects the further generation of melting process, so on reaction container top
Portion has opened another hole and has installed bye-pass III 31, and this branch road drying filter 5 is connected with absorber 7.Top gas contains on a small quantity
Water vapour, drying filter 5 is dried and enters absorber 7 bottom, and when the time comes, solution pump 12 is opened, absorber 7 and generator 15 it
Interior DMF solvent circulates between, completes the absorption to the R134a steam from reaction container top.
