As preferably, the side of air-cooled condenser also is provided with blower fan, on the air-cooled condenser export pipeline blower fan temperature controller is housed.The blower fan temperature controller is used for the start and stop of control blower fan.Equipment is provided with dual overtemperature protection, compressor internal protection and equipment overtemperature prote.Compressor internal protection: the i.e. pressure overload protection of compressor inside; The equipment overtemperature prote: namely can shut down during device compressor delivery temperature to 120 ℃, this shutdown needs again opening device of manual reset, plays like this effect of guarantee for equipment long-time running under various relative rugged environments.
As preferably, on the evaporating pressure constant valve export pipeline dew point indicator is installed.Dew point indicator makes things convenient for the facilities for observation performance.
Plate-sheet-type cooling driers according to the technical solution of the utility model, adopt plate type heat exchanger, collection evaporimeter and heat exchanger are that (heat exchanger partly adopts with the fine copper solder same integral body, in vacuum brazing furnace, the soldering of adjacent stainless steel corrugated cardboard sheet is formed, plate forms passage, pore size distribution on the corner is alternately flowed two media in passage, contact point multimachine tool intensity is good, and contact point and edge are sealed by copper brazing, has the heat exchange efficiency height, the cold-producing medium loading is little, structure is tightly played, and volume is little, and is lightweight, sealing factor is high, and voltage withstand class is up to arriving advantage durable in use).Moisture trap adopts the built-in stainless steel cloth manufacturing of 306 stainless steel tubes to form.Smooth vertical and horizontal with each tube connector that bending machine bends, Assurance of Size.Reasonable in design, solder joint is few, leakage rate is low, be convenient to install, rust corrosion, service life of equipment are not long.
Adopt the nano-hydrophilic membrane material to make the fin of air-cooled condenser, have good hydrophily, resistance to corrosion and automatically cleaning ability, gas-flow resistance is little, fin can increase compressed-air actuated flow-disturbing effect, heat exchange efficiency improves more than 1.1 times, hydrophilic fin can reduce the Wet Compression air drag, reduces crushing.Air-cooled condenser adopts overhead to install, the high hot compression refrigerating fluid of getting rid of from compressor be introduced into the top layer heat exchange copper tube again according to layer toward dirty, rationally adopted the radiating principle of heat; Blower fan adopts the air-exhaust type blower fan and gathers the temperature control of refrigeration pipe, and fan starting when its temperature reaches setting value lowers the temperature of air-cooled condenser, outside the hot blast remover apparatus, reaches best overall performance.
Each air vent of case shell adopts honeycomb hole, it has increased the area of port, thereby improve the overall performance of equipment, adopt the security feasibility of the nearlyer step raising equipment of design of honeycomb hole, the honeycomb hole employing length of side is that the regular hexagon punching of 5mm forms, when equipment installation or maintenance, can not touch the equipment the inside, both guarantee that the heat exchange fin of the air-cooled condenser in top was not bent, guarantee again the benefit that the installer does not scratch to fin.
Adopt automatic water trap, both saved electric energy, again the effectively eliminating that condensate liquid is intact.The condensate liquid of moisture trap inside flows to automatic water trap toward dirty, and built-in ball float is risen, and under internal pressure, moment is discharged condensate liquid.
The import and export temperature difference is low, only has 3 ~ 4 degree, so the compressed air relative humidity of equipment outlet is low, downstream pipeline outer surface the dewfall phenomenon can not occur.
Description of drawings
Fig. 1 is the schematic flow sheet of plate-sheet-type cooling driers of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail:
The plate-sheet-type cooling driers, comprise casing, box house is provided with refrigeration compressor 1, forecooler 7, evaporimeter 6, air-cooled condenser 2 and moisture trap 8, forecooler 7 is connected connection with evaporimeter, evaporimeter 6 is connected connection with moisture trap, moisture trap 8 is connected with water trap 9, and moisture trap 8 also is connected with air pipe with the downstream by forecooler 7; Refrigeration compressor 1 is connected with air-cooled condenser 2, and liquid feeding interface 10 is installed on the refrigeration compressor 1, on refrigeration compressor 1 blast pipe Overtemp. protector 13 is installed.The side of air-cooled condenser 2 also is provided with blower fan 3, on air-cooled condenser 2 export pipelines blower fan temperature controller 12 is housed.Air-cooled condenser 2 is connected with device for drying and filtering 4, and device for drying and filtering 4 is connected with evaporimeter 6 by evaporating pressure constant valve 5 again.On evaporating pressure constant valve 5 export pipelines dew point indicator 11 is installed.
