Below in conjunction with the drawings and specific embodiments, the utility model is further described.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is a kind of air heat energy negative pressure regeneration compressed air absorption drier, and it comprises the first adsorption tower 1, the second adsorption tower 2, freezing dehumidifier 3, semiconductor cooler 4, regeneration gas heater 5, air exhauster 6, adjustable throttling 7, four 81,82,83,84, six one- way exhaust valves 91,92,93,94,95,96 of stop valve.
Described air exhauster 6 connects respectively the entrance of the first adsorption tower 1 and the entrance of the second adsorption tower 2 by pipeline, be separately installed with the outlet of stop valve 81,82, the first adsorption towers 1 and the outlet of the second adsorption tower 2 and be connected dry-pressing contracting air outlet slit 10 by the pipeline that one- way exhaust valve 91,92 is housed respectively on this connecting pipe.Otherly respectively on the pipeline be connected at the entrance of the entrance of air exhauster 6 and the first adsorption tower 1 and the second adsorption tower 2 connect an admission line, the one- way exhaust valve 93,94 for pressure release is installed on this admission line.
Described freezing dehumidifier 3 and regeneration gas heater 5 are arranged on respectively huyashi-chuuka (cold chinese-style noodles) and the hot side of semiconductor cooler 4.Described freezing dehumidifier 3 is one to carry out cooling and carries out the device of gas-water separation compressed air, the external Wet Compression air of the entrance 20 of freezing dehumidifier 3, its outlet is connected with the entrance of the second adsorption tower 2 with the entrance of the first adsorption tower 1 by the pipeline that stop valve 83,84 is housed respectively.Adjustable throttling 7 is installed on the entrance of regeneration gas heater 5, and outlet connects the outlet of the first adsorption tower 1 and the outlet of the second adsorption tower 2 by the pipeline that check valve 95,96 is housed respectively.
This device is Double-Tower Structure, and when a tower, during in adsorption process, another tower is in the desorption and regeneration flow process, and when the first adsorption tower 1, in adsorbed state, the second adsorption tower 2 is in desorbing state, and stop valve 81,84 is opened, and stop valve 82,83 is closed; When the first adsorption tower 1, in desorbing state, the second adsorption tower 2 is in adsorbed state, and stop valve 82,83 is opened, and stop valve 81,84 is closed;
Its workflow is as follows:
1, adsorption process: compressed air is introduced into freezing dehumidifier 3, thereby here gas temperature drops to below environment temperature and then carries out gas-water separation and reduced humidity.Then enter the first adsorption tower 1 or the second adsorption tower 2 by stop valve 81 or 82, be adsorbed in flow process from bottom to top that moisture has been adsorbed in agent and drying obtains gas product.Discharge and enter pipe-line system by top again.
2, desorption process: when the stop valve 83 or 84 at the bottom of the tower of the first adsorption tower 1 or the second adsorption tower 2 is opened, it is emptying to allow pressure-air pass through one- way exhaust valve 93,94 that air exhauster 6 postpones start, then air exhauster 6 starts are bled from the first adsorption tower 1 and the second adsorption tower 2, while in tower, being negative pressure, the gas flow to from choke valve 7 is swollen is heated to 50 to 60 degrees centigrade through regeneration gas heater 5 rising, and adsorbent is brushed to regeneration.
3, all press and switching: by programme-control, stop at the appropriate time bleeding and closing valve, the tower that completes desorption is carried out to pressurising, exchange adsorption/desorption state when reaching with another tower uniform pressure.
Operation principle of the present utility model:
Adsorbent under high pressure adsorb and under negative pressure easy desorption, but be unfavorable for desorption because temperature reduces while vacuumizing.So the utility model adopts, surrounding air is expanded after heating under negative pressure state to the adsorbent desorption of being regenerated, the temperature needed is not high, and heat comes from the heat that thermoelectric heat pump absorbs from processed compressed air, these heats were the low grade heat energy that is taken as waste heat discharge originally.Its corresponding electric energy consumed is little, because the electrical efficiency of thermoelectric heat pump heat production is far above more than 1, (some typically can up to 200% or more).The usefulness of other Electric heating can only be lower than 1.On the other hand, because entrance compressed air is first in advance through freezing reduction humidity, brought two benefits: at first because adsorbent bed in tower just passes through low-temp recovery, temperature is not high, lower inlet tower gas temperature, just saved the process of adsorbent bed being carried out to blast-cold, flow process is become simply, be conducive to the adsorption moisture of adsorbent simultaneously; Secondly, entrance compressed air, through having reduced in advance the humidity load, can extend the time of adsorption process and the time of desorption and regeneration comparatively speaking, because of the also corresponding minimizing of consumption that switching state needs to discharge gas product, has greatly improved the economy of this device product.
Emphasis of the present utility model just is: the absorption drier of Double-Tower Structure, utilize semiconductor cooler to hold concurrently compressed air carried out pre-wet down and the regeneration thermal source is provided, and under negative pressure state, adopt the low hot gas of low discharge to brush the mode that adsorbent makes its regeneration.
The above, it is only the utility model preferred embodiment, therefore can not limit the scope that the utility model is implemented with this, the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
