Abstract
The utility model discloses a dryer for compressed air in a refrigeration room. The dryer comprises a refrigerating compressor, an evaporimeter and a precooler, wherein both the refrigerating compressor and the precooler are communicated with the evaporimeter through pipelines, and an air outlet and an air inlet are formed on the precooler. Due to the adoption of the scheme, the phenomenon of pipeline dewing can be effectively prevented, low temperature air is used for precooling of inlet gas, the energy is saved, the load of a refrigeration system is reduced, and the drying effect is improved greatly.
Description
Technical field
The utility model relates to a kind of dried-air drier, relates to a kind of refrigerating chamber compressed air drier that is applicable to pesticide producing specifically, belongs to the pesticide producing equipment technical field.
Background technology
In pesticide producing, the purification of air is had relatively high expectations, because the air engine discharge is a kind of inferior thick gas, contain a large amount of steam, dust, greasy dirt can not satisfy the demand that GAS QUALITY is had relatively high expectations.Therefore need purify compressed air, dried, existing drying machine mainly comprises absorption drier and freezing type drier.Wherein freezing type drier mainly makes airborne moisture content condensation reach dry through adopting refrigerant directly to cool off air; But pipeline dewfall phenomenon often appears in the drying machine of present this structure; Cause drying effect poor; Absorption drier mainly reaches dry purpose through the airborne steam of adsorbents adsorb, but the shortcoming of this absorption drier is that complex structure, drying effect are poor, can not satisfy in the pesticide producing process requirement to air quality.
The utility model content
The problem that the utility model will solve provides a kind of simple in structure, refrigerating chamber compressed air drier that drying effect is good.
In order to address the above problem, the utility model adopts following technical scheme:
A kind of refrigerating chamber compressed air drier comprises refrigeration compressor, evaporimeter and forecooler, and said refrigeration compressor and forecooler pass through pipeline connection with evaporimeter respectively, and said forecooler is provided with air outlet slit and air intlet.
Below be the further optimization of the utility model to such scheme:
Said forecooler and evaporimeter directly are provided with moisture trap; Said moisture trap is communicated with forecooler and evaporimeter respectively; Said compressed air gets into forecooler from air intlet, discharges from the air outlet slit of forecooler through evaporator, moisture trap then again.
Further optimize: the bottom of said moisture trap is connected with ball valve and automatic water trap.
The import and export of said refrigeration compressor respectively with evaporimeter in the exit port of condenser pipe pass through pipeline connection.
On the outlet of said refrigeration compressor and the pipeline between the evaporator condenser, filter, visor and heating power expansion valve are installed successively.
Said condenser is provided with water regulating valve and water filter.
This pipeline also is parallel with bypass line, on bypass line, is provided with heating power expansion valve, and said heating power expansion valve is electrically connected with high and low voltage switch.
Further optimize: on the import of said refrigeration compressor and the pipeline between the evaporator outlet gas-liquid separator is installed.
The utility model adopts such scheme; Its operation principle is: heat and compressed air moist and that contain oil content gets into forecooler through air intlet; Carry out heat exchange with the compressed air that cools off from evaporator dry, reduce compressed-air actuated saturation temperature, remove some moisture; Get into evaporimeter again; Make compressed air be cooled to pressure leak source 1.7 deg.c, moisture, oil content and partial impurities are separated through moisture trap, and moisture, oil content and impurity etc. sink to the bottom through ball valve and automatic water trap and discharges.
Dried Cryogenic air gets into forecooler normal temperature after air outlet slit output; Thereby prevented that effectively pipeline dewfall phenomenon from taking place; Utilize Cryogenic air to carry out the precooling inlet gas, the energy of not only having practiced thrift but also the load that has reduced refrigeration system have improved drying effect greatly.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Among the figure: the 1-refrigeration compressor; 2-heating power by-passing valve; The 3-condenser; The 4-filter; The 5-visor; The 6-heating power expansion valve; The 7-evaporimeter; The 8-gas-liquid separator; The 9-high and low voltage switch; The 10-forecooler; The 11-moisture trap; The 12-ball valve; The 13-automatic water trap; The 14-water regulating valve; The 15-water filter; The 16-air outlet slit; The 17-air intlet.
The specific embodiment
Embodiment; As shown in the figure, a kind of refrigerating chamber compressed air drier comprises refrigeration compressor 1, evaporimeter 7 and forecooler 10; Said refrigeration compressor 1 passes through pipeline connection with evaporimeter 7 respectively with forecooler 10, and said forecooler 10 is provided with air outlet slit 16 and air intlet 17.
Said forecooler 10 directly is provided with moisture trap 11 with evaporimeter 7; Said moisture trap 11 is communicated with forecooler 10 and evaporimeter 7 respectively; Said compressed air gets into forecooler 10 from air intlet 17, discharges from the air outlet slit 16 of forecooler 10 through evaporator 7, moisture trap 11 then again.
The bottom of said moisture trap 11 is connected with ball valve 12 and automatic water trap 13.
The import and export of said refrigeration compressor 1 respectively with evaporimeter 7 in the exit port of condenser pipe pass through pipeline connection.
On the pipeline between the outlet of said refrigeration compressor 1 and evaporimeter 7 imports condenser 3, filter 4, visor 5 and heating power expansion valve 6 are installed successively.
Said condenser 3 is provided with water regulating valve 14 and water filter 15.
