The specific embodiment

For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

Fig. 2 shows an embodiment of the vortex cooler that the utility model provides, and as shown in Figure 2, this vortex cooler comprises a thermal insulator 22, vortex tube 21 and condenser 23.The cold air outlet of vortex tube 21 is connected with the internal chamber of thermal insulator 22, and condenser 23 is inserted in the internal chamber in the thermal insulator 22.

Fig. 3 shows concrete structure and the course of work of the vortex cooler among Fig. 2.As shown in Figure 3, after the compressed air that pressure is generally 0.2-0.5MPa sprays the minor air cell 215 of vortex tube 21 from the air inlet 211 of vortex cooler 21, owing to be provided with a nozzle 216 near vortex tube 21 air inlets 211, this nozzle 216 makes the stratification of hot gas that enters wherein by Archimedes's path High Rotation Speed, so that minor air cell's 215 core gas temperatures of vortex tube 21 reduce, and outer gas temperature raises and the hot gas that flows to vortex tube 21 brings out mouthful (being the right side of vortex tube 21 among Fig. 3), wherein a part of gas flows out by control valve 213, after residual gas is stopped by diversion sleeve 214, counter-rotate with same rotating speed at former air-flow inner ring, and flow to the cold air end (being the left side of the vortex tube 21 among Fig. 3) of vortex tube 21, in this process, two bursts of air-flow generation heat exchanges, interior ring air-flow becomes terribly cold, discharge from the cold air outlet 212 in left side, it is awfully hot that the outer shroud air-flow then becomes, and discharges from the right side.Temperature and the uninterrupted of the cold air of discharging from the cold air outlet 212 of vortex tube 21 can be by control valve 213 controls of regulating the vortex tube right side, particularly, higher from the control valve 213 effluent air ratios of vortex tube 21, the temperature of the air-flow of then going out from the cold air outlet 212 of vortex tube 21 is just lower, and flow also correspondingly reduces.

Fig. 4 shows the concrete structure of the part of condenser among Fig. 2 and thermal insulator.As shown in Figure 4, the cold air outlet 212 of vortex tube is inserted in the internal chamber of thermal insulator 22, the cold air source is provided to thermal insulator 22 inside, condenser 23 can be interior arbitrarily along the direction extraction of arrow Fig. 4 from thermal insulator 22, is inserted into the position of thermal insulator 22 not such as available technology adopting cover plate and the fixing mode of screw at condenser 23.After being inserted into condenser 23 in the thermal insulator 22, condenser 23 is provided with an end of air inlet 231 and gas outlet 236 and stretches out from the end (being the left end of the thermal insulator 22 Fig. 4) 221 of thermal insulator 22 internal chamber, and the end that condenser 23 is provided with condensed water outlet mouth 234 stretches out from the other end 222 of thermal insulator 22 internal chamber.In use, sample gas enters into condenser 23 from the air inlet 231 of condenser 23, and the tube wall by condenser 23 carries out heat exchange with the cold air that is passed in the thermal insulator 22 in the process of circulation in condenser 23, sample gas reduces in the heat exchanging process temperature, condensed water is separated out at 234 places after the condensed water outlet of condenser 23, obtains dried sample gas from the gas outlet 233 of condenser 23.Here, thermal insulator 22 effects of starving are to stop extraneous thermal current near heat exchanger, and thermal insulator 22 can be made by polytetrafluoroethylmaterial material.

The material of condenser can have a variety of, below describes with two kinds of concrete materials respectively.

Fig. 5 is the structural representation of the condenser made by stainless steel, as shown in Figure 5, the air inlet 231a of this condenser and gas outlet 236a are positioned at the same end of condenser, condensed water outlet mouth 234 is positioned at the other end of condenser, condenser from air inlet 231a to condensed water outlet after the end of 234a be spiral element, one section from condensed water outlet mouth 234a to gas outlet 236a is passed from spiral element.

Condenser is water knockout drum 233a near being positioned at condensed water outlet mouth 234a, water knockout drum 233a container of realizing gas-water separation, and it belongs to the part of condenser, can fix by welding and other bodys of condenser.Sample gas is when flowing through condenser, and vaporous water liquefy water can be realized gas-water separation by this water knockout drum 233.

Be provided with connecting end surface at the air inlet 231a of condenser and the outside of gas outlet 236a, when condenser was inserted into the internal chamber of thermal insulator 22, connecting end surface contacted with the outer wall of thermal insulator 22.

Need to prove, between the connecting end surface of the condenser among Fig. 5 and the body and body adopt the mode of outside weldings to be fixed with connecting portion between the water knockout drum to be connected, to be difficult for like this leakage sample gas.

Fig. 6 is the structural representation of the condenser made by glass, and as shown in Figure 6, the air inlet 231b of this condenser and gas outlet 236b still are positioned at the same end of condenser, and condensed water outlet mouth 234 is positioned at the other end of condenser.The end of condenser from air inlet 231b to condensed water outlet mouth 234b is spiral element, and one section from condensed water outlet mouth 234b to gas outlet 236b is passed from spiral element.

Because the condenser among Fig. 6 is made by glass, because manufacture craft is different from the condenser among Fig. 5, so the condenser among Fig. 6 can be one-body molded.However, the condenser that adopts glass to make is appointed the zone that so can mark off as water knockout drum 233b near being positioned at condensed water outlet mouth 234b.The water knockout drum 233b here is identical with water knockout drum 233a role among Fig. 5.

Different from the condenser among Fig. 5 is, air inlet 231b and gas outlet 236b at condenser do not arrange special connecting end surface, but the design external diameter is substantially equal to the entrance hole diameter that thermal insulator 22 is used for inserting condenser near air inlet 231b and gas outlet 236b, when being inserted into condenser in the thermal insulator, the end that condenser arranges air inlet 231b and gas outlet 236b can adapt with the opening of thermal insulator like this.

Adopt glass to make the manufacturing cost that condenser can reduce condenser, the condenser raw material of glass material is clean simultaneously, and corrosion resistance is stronger.

No matter be to adopt condenser among Fig. 5 or the condenser among Fig. 6, the vortex cooler that the utility model provides can be realized the fast assembling-disassembling of condenser easily.

The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
