Description
Technical field
The utility model relates to a kind of heat exchanger, especially relates to a kind of cooling driers unitized exchanger.
Background technology
Common middle-size and small-size cooling driers unitized exchanger mostly is Dual-barrel-shaped, and its precooling-reheater and evaporimeter are installed in respectively two independently in the cylindrical vessel, and the two linked to each other by communicating pipe, and the evaporimeter back arranges simple plate washer as gas and water separator.This structure gas and water separator gas-water separation effect when compressed air require changes fluctuates greatly, and separative efficiency is not high; In addition, compressed air is generally the following current heat exchange in the heat exchange of precooling-reheater, the shortcoming that this heat exchange mode exists is: pre-cooled weak effect, Load Evaporator is large, precooling-reheater has not been given play to due usefulness as the important energy-conservation parts of compressed air cooling driers, the exit compressed air temperature is lower simultaneously, and relative humidity is higher, causes that easily the bad phenomenon such as downstream compressed air piping inside and outside wall condensation drips occur.
The utility model content
The deficiencies such as the heat exchange efficiency that exists in the present technology is low in order to overcome, the gas-water separation effect is relatively poor, the utility model provides the cooling driers unitized exchanger of a kind of heat exchanger efficiency height and the better gas-water separation effect of tool.
A kind of cooling driers unitized exchanger, described heat exchanger comprise the precooling that be arranged in parallel-reheater cylinder and evaporimeter cylinder, are interconnected by two communicating pipes between two cylinders, and described each cylinder two ends all are welded with circular shrouding; In precooling-reheater cylinder precooling-reheater is installed, precooling-reheater cylinder one side is provided with compressed air inlet pipe and compressed air escape pipe; In the evaporimeter cylinder evaporimeter is installed, the evaporimeter bottom of cylinder is provided with discharge outlet, and evaporimeter cylinder inner wall one side is provided with " L " shape dividing plate; The circular shrouding of evaporimeter one end is provided with refrigerant feed tube and refrigerant escape pipe, and described refrigerant feed tube and refrigerant escape pipe pass circular shrouding and fix with it; Described precooling-reheater and evaporimeter are equipped with some deflection plates.
Preferably, described precooling-reheater is shell-and-tube heat exchanger, and evaporimeter is the cover Flat-tube type heat-exchanger.
Preferably, described precooling-reheater cylinder and evaporimeter cylinder be arranged in parallel up and down, described two communicating pipe is respectively the first communicating pipe and the second communicating pipe, be located at the first communicating pipe precooling-reheater cylinder under or the evaporimeter cylinder directly over, be located at the side of two cylinders the second communicating pipe and be communicated with " L " shape dividing plate.
Preferably, described precooling-reheater two ends and forecooler cylinder inner wall welding.
Preferably, described " L " shape dividing plate and evaporimeter cylinder inner wall welding.
Preferably, the circular seal plate welding of described refrigerant feed tube and refrigerant escape pipe and evaporimeter.
The utility model is applicable to the middle low discharge compressed air that contains a large amount of liquid moisture is carried out cooling de-watering and effective separation draining.
The utility model compact conformation is the adverse current heat convection because the heat exchange method of compressed air in precooling-reheater adopt, makes it have that heat transfer temperature difference is large, the heat exchange amount greatly, effectively reduces the advantages such as compressed air cooling driers energy consumption; In addition, at evaporimeter cylinder inner wall one side setting " L " shape dividing plate, have better, more stable gas-water separation effect.

Fig. 2 is side view of the present utility model.
Fig. 3 is the structural representation of the utility model " L " shape dividing plate.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, a kind of cooling driers unitized exchanger, comprise the precooling that be arranged in parallel up and down-reheater cylinder 5 and evaporimeter cylinder 12, between two cylinders by being interconnected the first communicating pipe 8 and the second communicating pipe 7, precooling-reheater cylinder 5 two ends are welded with circular shrouding 6, and evaporimeter cylinder 12 two ends are welded with circular shrouding 11; In precooling-reheater cylinder 5 precooling-reheater 4 is installed, precooling-reheater cylinder 5 one sides are provided with compressed air inlet pipe 2 and compressed air escape pipe 1; Evaporimeter 14 is installed in the evaporimeter cylinder 12, and evaporimeter cylinder 12 bottoms are provided with discharge outlet 16, and evaporimeter cylinder 12 inwalls one side is provided with " L " shape dividing plate 15; The circular shrouding 11 of evaporimeter 14 1 ends is provided with refrigerant feed tube 9 and refrigerant escape pipe 10, and described precooling-reheater 4 is provided with deflection plate 3, and evaporimeter 14 is provided with deflection plate 13.The welding of precooling-reheater 4 two ends and forecooler cylinder 5 inwalls, " L " shape dividing plate 15 and the welding of evaporimeter cylinder 12 inwalls, the refrigerant feed tube 9 of evaporimeter 14, escape pipe 10 pass the circular shrouding 11 of evaporimeter and with its welding.
The saturated compressed air of normal temperature enters precooling-reheater 4 shell sides from air inlet pipe 2 first, carry out countercurrent heat exchange and obtain pre-cooled with the compressed air after dewatering through evaporimeter 14 cooling, flow through communicating pipe 8 through pre-cooled compressed air, evaporimeter 14 coolings are also separated out liquid moisture, the gas and water separator that consists of via " L " shape dividing plate 15 and evaporimeter cylinder 12 inwalls again, most of aqueous water that condensation goes out is separated, isolated moisture falls into evaporimeter cylinder 12 bottoms and discharges from discharge outlet 16, the compressed air that separates after dewatering carries out countercurrent heat exchange by the saturated compressed air of precooling-reheater 4 tube sides and entrance normal temperature of flowing through communicating pipe 7, here compressed air temperature gets a promotion, relative humidity significantly reduces simultaneously, discharges by escape pipe 1 at last.
This novel unitized exchanger is integrated precooling-reheater, evaporimeter, the set of gas-water separation function, compact conformation, cost are low, resistance decrease little, minute water is effective, precooling-the reheater of countercurrent flow obtains higher outlet air temperature when alleviating the evaporimeter cooling load, promoting middle-size and small-size freezing type drier energy-saving effect, the generation of the bad phenomenon such as can avoid better compressed air downstream pipeline inside and outside wall condensation, drip.
