Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of the utility model embodiment；
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described, but the utility model is not limited
In these embodiments.
With reference to accompanying drawing 1, a kind of high-efficiency and energy-saving type frequency conversion freezing type drier is by air system, refrigeration system and control
System composition.
Air system has air-cooled forecooler 1, heat exchanger 2, evaporator 3, gas-liquid separator 4, and compressed air passes through air-cooled pre-
Cooler precooling enters heat exchanger, and heat exchanger is the part that a kind of air carries out heat exchange with air, and the main function of heat exchanger is
Cold after " recovery " is cooled down by evaporator entrained by compressed air, and cooled down with this part cold and to carry a large amount of vapor
The compressed air of higher temperature, so as to alleviate the thermic load of cooling driers refrigeration system, reaches the purpose for saving energy；Enter afterwards
Evaporator, heat exchange is carried out with refrigerant, and refrigerant absorbs the heat of compressed air wherein, realizes the purpose dehydrated；
Gas-liquid separator is finally entered, aqueous water is separated from cooled compressed air, the double evaporation-cooling of moisture is prevented, protected
Demonstrate,prove the dew point quality of cooling driers part finished product gas.
Refrigeration system in the present embodiment belongs to compression-type refrigeration, by Refrigerating Compressor with Inverter 5, oil eliminator 6, condenser
7th, device for drying and filtering 8, capillary 9 and hot gas bypass valve 10 are constituted.Refrigerating Compressor with Inverter is (low by the low pressure in evaporator
Temperature) refrigerant suction compressor cylinder in, refrigerant vapour is raised simultaneously through overcompression, pressure, temperature；The refrigeration of high pressure-temperature
Agent steam is depressed into condenser by oil eliminator, and oil eliminator is by the lubrication in the high steam of Refrigerating Compressor with Inverter venting
Oil is separated.In condenser, the higher refrigerant vapour of temperature carries out hot friendship with temperature than relatively low cooling water or air
Change, the heat of refrigerant is taken away and condensed out by water or air, and refrigerant vapour becomes liquid.This partially liq is defeated again
Capillary is delivered to, by capillary-compensated is into the liquid of low-temp low-pressure and enters evaporator；Low temperature, low pressure in evaporator
Refrigerant liquid absorbs the heat of compressed air and vaporizes and (be commonly called as " evaporating "), and compressed air condenses out largely after being cooled down
Liquid water；Refrigerant vapour in evaporator is siphoned away by compressor again, and such refrigerant is just in systems through overcompression, cold
Coagulate, throttle, evaporating such Four processes, so as to complete a circulation.Heat is also equipped between oil eliminator and evaporator
Gas by-passing valve, hot gas bypass valve is used to prevent the short-circuit cycle of compressor, prevents compressor work under low-down pressure of inspiration(Pi)
Make, while preventing that evaporator freezes during underload.
Control system is made up of controller 11 and temperature sensor 12, and temperature sensor is used for the temperature for detecting evaporator outlet
Degree, adjusts Refrigerating Compressor with Inverter running frequency, so as to adjust change by evaporator outlet temperature analog signalses by controller
Frequency refrigerant compression unit frequency, causes the device to adapt to a variety of operating modes, accomplishes energy-conservation on the premise of cooling driers performance is ensured
Operation, is allowed to be in optimal rotary regimes.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement or using similar to described specific embodiment
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
