A kind of vortex effect refrigeration device

The utility model relates to a kind of refrigerating plant, specifically, relates to a kind of device that utilizes the universal compressed air cooling in industrial and mining enterprises' production process.

At present, general compressed air piping generally all is equipped with in each workshop of some relatively large industrial and mining enterprises.Its compressed air has plenty of in the production process necessary; Also has plenty of the byproduct in the production process, the few compressed air of oxygen content that is produced during as steel-making.These compressed air contain lot of energy, but has often slatterned in vain owing to utilize insufficient.On the other hand, electromechanical equipment is often heating or local temperature rising in running, need carry out local cooling.The industrial refrigeration machine that these electromechanical equipments are carried out local cooling is complex structure often, and volume is big, and the manufacturing cost height needs to consume a large amount of electric energy simultaneously, also will prevent the generation that leak-stopping fluorine etc. pollutes, thereby its operation and maintenance cost is also very big.

The purpose of this utility model is exactly the universal compressed air that utilizes in industrial and mining enterprises' production process, and a kind of refrigerating plant of simple and feasible is provided, and satisfies the needs of local coolings such as industry and Medical Devices.

The purpose of this utility model is achieved in that

1. be as power source with universal compressed air, utilize its pressure reduction, make universal compressed air in vortex cavity, produce a kind of helical rotation of Archimedes's formula, cause separating of outer thermal current and center cold airflow, with conduit cold airflow is drawn the cooling of realization to the equipment part again through the heating power conversion.

2. refrigerating plant is a kind of device of being made up of parts such as vortex generators, and vortex generator is made up of overcoat, inner core, regulating spool, adjusting bonnet.

The utlity model has following advantage and good effect:

1. because be to utilize universal compressed air in industrial and mining enterprises' production process as power source, no power consumption has plenty of twice laid, so has greatly saved the energy, has reduced the refrigeration cost.

2. the cold airflow temperature of Chan Shenging is low, can satisfy the needs of many equipment coolings.

3. because pollution-free, help environmental protection.

4. cooling device mainly is a vortex generator, and it is simple in structure, processes easily and installs, ratio of performance to price height.

5. easy to operate, do not need special maintenance.

The universal compressed air of P0-, P1-cleaning compressed air, promptly a kind of compressed air of anhydrous, no greasy dirt after treatment, P2-cold airflow, P3-thermal current.

The 1-stop valve; The 2-filter; The 3-pressure-reducing valve; The 4-muffler; The 5-vortex generator; The 6-cooler.5.1-overcoat, 5.1.1-P1 ingate, 5.1.2-P2 outlet opening, 5.1.3-pilot hole; 5.2-inner core, 5.2.1-air inlet, 5.2.2-vortex cavity; 5.3-regulating spool, 5.3.1-P3 fairlead, 5.3.2-P3 outlet plenum; 5.4-adjusting bonnet.

As shown in Figure 1, this refrigerating plant mainly is made up of the stop valve 1, pressure-reducing valve 2, filter 3, vortex generator 5, the cooling device 6 that connect successively.Universal compressed air P0 obtains after through stop valve 1, pressure-reducing valve 2, filter 3 cleaning compressed air P1 a kind of required pressure, anhydrous, no greasy dirt passes through vortex generator 5 again, obtains cold air P2, delivers to cooler 6.For abating the noise, muffler 4 is installed on vortex generator 5.

As shown in Figure 2, this vortex generator 5 is made up of overcoat 5.1, inner core 5.2, regulating spool 5.3, adjusting bonnet 5.4.Inner core 5.2 places in the overcoat 5.1, after regulating spool 5.3 places inner core 5.2, regulates bonnet 5.4 and is loaded on the inner core 5.2.After cleaning compressed air P1 enters inner core 5.2 through overcoat 5.1, produce helical rotation, cause separating of internal layer cold airflow P2 and outer thermal current P3.

As shown in Figure 3, overcoat 5.1 is processed by a metal cylinder, and its cylinder axis direction is processed with P1 ingate 5.1.1 and P2 outlet opening 5.1.2 up and down respectively, and two holes link with pilot hole 5.1.3 respectively, and wherein P2 outlet opening 5.1.2 is a bellmouth.

By Fig. 4, Fig. 5 as can be known, inner core 5.2 is a cylinder, and the outer uniform direction of its cylinder has 2-4 air inlet 5.2.1, and air inlet 5.2.1 and cylinder are tangent; In the cylinder vortex cavity 5.2.2.Cleaning compressed air P1 is introduced in the vortex cavity 5.2.2 by air inlet 5.2.1, because air inlet 5.2.1 and vortex cavity 5.2.2 are tangent, forms eddy current, and its centre cold airflow P2 is gone out through φ b orifice flow by vortex cavity 5.2.2.

As shown in Figure 6, the sealing of regulating spool 5.3, one ends is tapered, and the other end is the cylinder of hollow, is processed with 4 uniform apertures on cylindrical, i.e. P3 fairlead 5.3.1; On axis direction, have a P3 outlet plenum 5.3.2 who links with P3 fairlead 5.3.1.Thermal current P3 flows into P3 fairlead 5.3.1 along vortex cavity 5.2.2 inwall through regulating spool 5.3 left parts, flow out through P3 outlet plenum 5.3.2 again.
