Description
Technical field:
The utility model relates to a kind of freeze drying plant.
Background technology:
The compressed air that comes out from air compressor machine is a kind of sordid gas, wherein be mixed with plurality of impurities (comprising solia particle, water, wet goods) can bring little evil to production process and product quality, so compressed air is purified and dry the processing is being necessary aspect the industry.The preposition water-cooled forecooler of existing high-temperature water cooling freezing type drier, precooling regenerator, evaporimeter, moisture trap all adopt shell-tube type, they all make independently housing, because the heat transfer efficiency of shell and tube exchanger is poor, and is so machine shape is bigger, not energy-conservation again.
The utility model content:
In order to overcome above-mentioned drawback, the utility model provides a kind of freeze drying plant, can handle compressed air, and filter core is had automatic cleaning function, reduces resistance greatly, and operating cost is low and convenience is overhauled, maintenance.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of freeze drying plant, comprise casing and refrigeration pipe, it is characterized in that: this casing is provided with compressed air inlet, compressed air outlet, casing is built-in with preposition water-cooled forecooler, the precooling regenerator, the aluminium sheet fin heat exchanger that evaporimeter and moisture trap integrate, compressed air inlet successively with four unification aluminium sheet fin heat exchangers in preposition water-cooled forecoolers, the precooling regenerator, evaporimeter, moisture trap, be connected, compressed air outlet is communicated with the precooling regenerator, the refrigeration compressor exhaust outlet successively with water-cooled condenser, oil water separator, device for drying and filtering, evaporimeter in the aluminium sheet fin heat exchanger, the refrigeration compressor air suction mouth is connected.
Preferably, described aluminium sheet fin heat exchanger is external connects electronic water trap.
Preferably, between the refrigerant inlet of described device for drying and filtering and evaporimeter heating power expansion valve is set.
Preferably, the cold-producing medium inlet of the air inlet pipe of described water-cooled condenser, aluminium sheet fin heat exchanger, gas outlet link to each other with hot gas bypass valve respectively.
Preferably, described refrigeration pipe low-pressure side is connected with the refrigerant low-pressure meter; The refrigeration pipe high-pressure side is connected with the refrigerant high pressure gauge.
Preferably, on the refrigeration pipe between described refrigerant high pressure gauge and the refrigerant low-pressure meter high-low pressure force controller is installed.
The utility model changes the preposition water-cooled forecooler of traditional shell-tube type, precooling regenerator, evaporimeter, moisture trap into the aluminium sheet fin heat exchanger, and shell-tube type independently housing changes four monoblock types of unifying into.Because aluminium sheet fin heat exchanger heat transfer efficiency is good, heat transfer temperature difference is little, so the heat exchanger of identical heat exchange amount can be done forr a short time by volume, and more compact structure; The aluminium sheet fin heat exchanger air ports temperature difference is less, can accomplish 5 ℃, has reduced the thermic load of refrigeration system, and is energy-conservation more than 30%.The utlity model has cooling, dehumidifying, gas-water separation function, can effectively separate the liquid water droplets in the finished product gas, guarantee the quality of finished product gas; Also than common freezing type drier compactness, reduce about 1/3 on the structure than existing drying machine size; Be provided with gas and water separator, its outlet pressure dew point can reach 3 ℃, can satisfy the demand of the finished product gas of high request.
Description of drawings:
Fig. 1 is the structural representation of the utility model specific embodiment;
Among the figure: 1-refrigeration compressor, 2-water-cooled condenser, the electronic water trap of 3-, 4-device for drying and filtering, 5-heating power expansion valve, 6-refrigerant low-pressure meter, 7-hot gas bypass valve, 8-high-low pressure force controller, 9-refrigerant high pressure gauge, 10-oil water separator.
