After further being dehumidified into dehumidifier 2, the low temperature dry air of acquisition, by entering silo after air-to-water heat exchanger 15
27 pairs of grains are carried out with regard to storehouse low temperature drying, and volume damper III 26 is in close state at this time.
After drying, system is transferred to On Model of Low Temperature Grain, i.e. volume damper II 24, volume damper IV to grain during procedure of storing grain
28 close, and return air is filtered after the adjusting of volume damper III 26 by air filter 25 in storehouse, under the effect of blower II 23
Into evaporator 18, the cooled cooling of air carries out necessary dehumidifying subsequently into dehumidifier 2.Cryogenic air after dehumidifying is passed through
After air-to-water heat exchanger 15, into silo absorbing cabin in it is wet more than grain waste heat, then drain into outside storehouse in atmosphere.Into winter,
After meteorologic parameter is met the requirements, silo directly can be sent into using outdoor fresh air and realize low-temperature grain-storage, i.e. volume damper III 26
It closes, volume damper II 24, volume damper IV 28 are opened, and outdoor air passes through air mistake by volume damper II 24
Filter 25 filters, under the effect of blower II 23, after passing sequentially through evaporator 18, dehumidifier 2 and air-to-water heat exchanger 15, into
Enter silo 27, Cryogenic air absorb grain waste heat, it is remaining it is wet after, be discharged to outdoor by volume damper IV 28.
Heat pump cycle: corresponding silo ventilating system, under operational mode one, operational mode three or On Model of Low Temperature Grain, work
It is as follows to make process: for low pressure refrigerant gas after the compression boosting of compressor 17, higher pressure refrigerant gas enters air cooled condenser
19 are reproduced air cooling, condense into highly pressurised liquid.Highly pressurised liquid flows through the throttling of expansion valve 20, becomes low temperature, low pressure damp steam,
Heat exchange is carried out into evaporator 18 and the air by blower II 23, is gasified after low pressure liquid heat absorption therein, after gasification
Low pressure refrigerant gas is sucked again by compressor 17, to complete a heat pump cycle.Corresponding silo ventilating system, runs mould
Formula two, heat pump cycle is not run.
Solar water recycles: corresponding silo ventilating system, worked under operational mode one or On Model of Low Temperature Grain
Journey: through solar energy heating 13 heating after hot water under the action of water pump 12, be divided into two-way, all the way by plate heat exchanger 11 with
Solution by solution pump 5 exchanges heat, and adjusts 14 by water flow after being cooled.Another way hot water flows into Air-Water heat and hands over
Parallel operation 15 exchanges heat with the air for flowing through dehumidifier 2, by Water flow adjusting valve II 16 and through water flow tune after being cooled
The another way water of section valve I 14 is mixed, and subsequently into solar thermal collector 13, completes a circulation.Corresponding silo ventage
System operational mode two, the course of work is as follows: Water flow adjusting valve I 14 is closed, and the hot water after the heating of solar energy heating 13 is in water
It under the action of pump 12, exchanges heat by air-to-water heat exchanger 15 with the air for flowing through dehumidifier 2, passes through water after cooled
Flow control valve II 16 enters solar thermal collector 13, completes a circulation.Corresponding silo ventilating system, operational mode three, too
Positive energy hot water cyclesystem is not run.
Solution dehumidification recycles: corresponding silo ventilating system, under operational mode one, operational mode three or On Model of Low Temperature Grain,
Its course of work: the weak solution that dehumidification solution case 4 is discharged passes through liquid inventory regulating valve 10, into plate heat exchanger 7 and passes through
The concentrated solution all the way of solution regulating valve 9 exchanges heat, and is heated mixed with the another way concentrated solution Jing Guo liquid inventory regulating valve 8 afterwards
It closes, then under the action of solution pump 5, exchanges heat by plate heat exchanger 11 and by the hot water all the way of Water flow adjusting valve I 14
After heating, heat, mass transter are carried out with the regeneration air passed through into regenerator 1, the partial moisture in solution gets into the air, molten
Liquid realizes regeneration.Regenerated concentrated solution flows into actified solution case 3, then divides two-way, passes through flow control valve 8 all the way.Another way
By liquid inventory regulating valve 9, after cooling down into plate heat exchanger 7 with the weak solution heat exchange for flowing through liquid inventory regulating valve 10,
Enter dehumidifier 2 under the action of solution pump 6, solution absorbs the moisture in air, and solution concentration, which reduces, becomes weak solution inflow
Then dehumidification solution case 4 passes through liquid inventory regulating valve 10, recycle so as to complete one.It is regenerated in solution dehumidification circulation empty
The gas course of work are as follows: outdoor air passes through volume damper I 22, under the effect of blower I 21, into air cooled condenser 19, inhales
After receiving condensation heat, air themperature, which is increased, to be exchanged subsequently into regenerator 1 with regenerated solution progress caloic is needed, water in absorbent solution
Atmosphere is discharged into after point.Corresponding silo ventilating system, operational mode two, the solution dehumidification circulatory system are not run.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
