Abstract

The utility model discloses a spraying structure, which is particularly suitable for providing replenished atomized water for the evaporation heat exchange process. The utility model aims at solving the problem of providing a spraying structure which not only ensures that water replenished quantity is timely provided, but also ensures that a metal surface liquid film has enough evaporation time and space after injection stream acts the surface of a heat exchanger during replenishing water. The spraying structure comprises an air inlet pipe, a drainage conduit and a drainage joint of a water inlet pipe, and a spraying head with a nozzle. A gas-water mixing cavity is arranged in the spraying head; and a water outlet of the nozzle is linear. The influence range of the replenishing water on the evaporation effect of the metal surface is reduced, thereby achieving continuous water replenishment with minimized influence on the e evaporation effect of the metal surface. In addition, the spraying structure has good heat exchange effect and simple structure.

Description

Spray structure

Technical field

The utility model relates to a kind of spray structure, and especially being applicable to the evaporation and heat-exchange process provides additional atomized water.

Background technology

In existing spray structure, when nozzle during, generally all is that to adopt the aperture be the nozzle of circular hole to the action face spray fluid, when free space went out to flow outside container by the aperture, the disperse state of its jet nature always was coniform distribution at fluid high-speed.When this jet projects with its axis is on the plane of normal the time, and its projection surface is a circular flat.When if there is an angle in the normal on the axis of this jet and plane, its projection result is an elliptic plane.When adopting this pattern to consume, in the circle or elliptic plane of jet projection for the surface, evaporator metal keeps the skin wet.Even this circle or elliptic plane are in the motion, be subjected to the influence of moisturizing jet, metal surface humidity is increased, almost level off to saturatedly, so that the metal surface evaporative effect in this scope levels off to zero, causes the decrease in efficiency of evaporation and heat-exchange.

The utility model content

After injection stream affacted heat exchanger surface when technical problem to be solved in the utility model provided a kind of moisturizing, can guarantee the in good time rate of water make-up that provides, can the sufficient evaporation time and the spray structure in space be arranged guarantee fund's metal surface liquid film again.

The technical scheme that its technical problem that solves the utility model adopts is: spray structure comprises the shower nozzle of the drainage catheter of bringing tracheae and water inlet pipe into, flow sub, band nozzle being provided with the air water hybrid chamber in shower nozzle that the delivery port of nozzle is a wire.

As improvement of the present utility model, adopt flow sub to be connected between shower nozzle and the drainage catheter; Described flow sub is provided with respectively inlet channel and the intake tunnel with air inlet pipe and water inlet pipe UNICOM, and inlet channel and intake tunnel are respectively by tap air channel and drainage channel and described air water hybrid chamber UNICOM.

Adopt spray structure of the present utility model, because it is limited at the rectangle width of nozzle to go out to flow supplementing water, its jet is observed from another side in the length direction expansion of rectangle, and restricted jet forms the fan-shaped jet bigger than cone diameter.When adopting this restricted jet form to consume for the surface, evaporator metal keeps the skin wet, single injection stream area coverage greatly reduces, and expands to some extent at the length direction of rectangle, and when the spray structure broad ways was moved, its coverage rate was bigger.Therefore, supplementing water can realize the continuation moisturizing to metal surface water film evaporation effects minimum to the also corresponding minimizing of coverage of metal surface evaporative effect.And can on drainage catheter, arrange and satisfy the needs in the engineering by a plurality of nozzles.The good effect of heat exchange of spray structure of the present utility model, simple in structure.

The specific embodiment

As shown in Figure 1, spray structure mainly is made up of the shower nozzle 4 of the drainage catheter 7 of bringing tracheae 2 and water inlet pipe 3 into, band nozzle 5, and the delivery port of nozzle 5 is illustrated in figure 2 as length and grows and the less wire of width.After supplementing water and compressed air enter into the air water hybrid chamber 6 of shower nozzle 4 by air inlet pipe 2 and water inlet pipe 3 respectively, air conduction effect by compression, supplementing water is fan-shaped outside ejection from nozzle 5, forms long and narrow approximate linear projection surface and forms moisture film at this projection surface at the heat exchanger surface that spray structure acted on.Therefore, rotating because of spray structure in the relative motion process that forms with heat exchanger, carrying out heat exchange in the continuous evaporation of moisture film that the heat exchanger surface atomized water forms.In spray structure rotates the cycle in a week, the utility model with heat exchanger surface relative motion process in form the process of moisture film, compare with the moisture film process that existing circular hole nozzle forms, to the Influence of Evaporation minimum of metal surface, so can improve the evaporation and heat-exchange effect effectively.

For the ease of being connected of shower nozzle 4 and drainage catheter 1, adopt flow sub 7 to be connected between shower nozzle 4 and the drainage catheter 1.Flow sub 7 is provided with respectively inlet channel 11 and the intake tunnel 12 with air inlet pipe 2 and water inlet pipe 3 UNICOMs, and inlet channel 11 and intake tunnel 12 are respectively by tap air channel 9 and drainage channel 8 and described air water hybrid chamber 6 UNICOMs.Described inlet channel 11 is arranged on the middle part of flow sub 7, and is provided with intake tunnel 12 in the periphery of inlet channel 2.As shown in Figure 1, drainage catheter 1 is a double-decker, and the centre is an air inlet pipe 2, and skin is a water inlet pipe 3, air inlet pipe 2 and inlet channel 11 UNICOMs, water inlet pipe 3 and a plurality of intake tunnel 12 UNICOMs.Flow sub 7 is provided with the interface that 2～4 different directions are connected with shower nozzle 4, can connect one or 2 shower nozzles 4 as required.Unwanted interface during reality used adopts the sealing of interface end socket, has improved the interchangeability of flow sub 7 like this and can adjust according to field condition.

Adopting this flow sub 7 to also help on the extension of drainage pipe 1 when diverse location is arranged a plurality of shower nozzle 4 uses, promptly the end at flow sub 7 is connected with the drainage catheter 1 of water inlet direction, the other end is connected with extension drainage tube 13 roads, a supplementing water part of coming from the water inlet direction sprays from the nozzle 5 on the flow sub 7 like this, and part is in addition supplied with the flow sub and the nozzle of back from extending drainage tube 13.

For the amount of makeup water in the air water hybrid chamber 6 that guarantees to enter shower nozzle 4, with half UNICOM in the intake tunnel 12 in drainage catheter 1 and the flow sub 7 that extends drainage tube 13 UNICOMs, second half sealing.Drainage catheter 1 as the left side among Fig. 1 is a supplementing water UNICOM state with extending drainage tube 13, the right is a closed state, supplementing water enters the air water hybrid chamber 6 by intake tunnel 12, drainage channel 8 from the water inlet pipe 3 of drainage catheter 1, and simultaneously unnecessary supplementing water flows to and the intake tunnel 12 that extends drainage tube 13 UNICOMs by another drainage channel.Therefore, each flow sub 7 both obtained replenishing of required water source for the shower nozzle that is connected with this flow sub 7, provided water stream channel for follow-up extension drainage tube again.When flow sub 7 no longer need continue to extend the time, adopt the end socket sealing to get final product.

The axis of described tap air channel 9 and flow sub 7 axially vertical and consistent with the center line of nozzle 5, help compressed air in air water hybrid chamber 6 with after supplementing water is mixed, to the drainage of supplementing water.
