Description
Technical field
The utility model relates to a kind of heater, especially relates to the heater of a kind of steam and water blending heating.
Background technology
At present, carbonated drink heater mainly contains two classes, and a class adopts dividing wall type heat exchanger, and namely steam does not contact with water, and steam is condensed into water by heater, and water becomes the higher water of temperature through heater; An other class adopts carbonated drink mixing device, and namely steam directly contacts with water, normally a steam inlet tube and a water inlet pipe, and in steam-water mixing space, steam-condensation becomes water and mixed by the water heated, and finally flows out from a water outlet pipe.Steam and water blending heating adopt an inner nozzle to add an overcoat steam pipe composition usually, steam pipe top connects a steam inlet tube, and such as CN86207953 discloses one " steam water heater ", CN86207574 open a kind of " direct contact heater with laval nozzle " and CN201420361429.9 discloses one " squelch type steam-water injection ".The usual heat transfer effect of steam water mixed heating device is better; but steam produces phase transformation when its maximum problem is carbonated drink contact; volume reduces rapidly; easy generation water hammer, vibration and noise etc., particularly steam pipe enters on top, directly impacts inner jet pipe; this makes jet pipe top and the bottom discontinuity; the steam nozzle speed of jet pipe is also uneven up and down, and the quantity of steam entering top and the bottom in jet pipe not etc., does not cause the top and the bottom of delivery port to there is the larger temperature difference.Unbalance stress is the root producing vibration & noise, finally also affects heating effect, increases the temperature difference heat stress of heater, affects heater life.In order to improve these shortcomings, CN86207574 open a kind of " direct contact heater with laval nozzle ", between jet pipe and housing, packing copper scale carrys out the momentum of cuisine steam, CN201420361429.9 discloses one " squelch type steam-water injection ", adds quartz filler layer in the vapor space.Although adopt the method for adding filler buffering can improve the uniformity coefficient of steam to a certain extent, but because steam nozzle directly aims at inner jet pipe, the unbalance stress of top and the bottom is caused to be difficult to avoid, in addition, filler washing away for a long time by steam, drawing small, the filler shortened that fractures just enter in water with steam hole, and impact heating water quality even destroys pipeline and the equipment in downstream.CN201210126973.0 discloses one " steam-water injection ", by steam inlet central axis and Rafael nozzle center axis deviation certain distance, decrease the vibration of equipment to a certain extent, but, this import mode remains asymmetrical, cause heater stressed still uneven, be finally difficult to avoid producing vibration.
Utility model content
The purpose of this utility model overcomes deficiency of the prior art, provides a kind of jet pipe uniform force, all even heating-up temperature of admission even, can realize quiet and steam-water injection that is high-quality heat transfer effect.
In order to solve the problems of the technologies described above, the utility model provides a kind of steam-water injection, comprise the Rafael nozzle be connected in sequence by reducing pipe, straight tube and increaser, be arranged on the water inlet pipe of described jet pipe one end and be arranged on the outlet of the other end, be provided with convergent static mixer in described water inlet pipe and reducing pipe, in described outlet and increaser centre, be provided with flaring static mixer; Steam hole is respectively arranged with on the tube wall of described straight tube and on the tube wall being attached thereto the increaser end connect; Described straight tube is provided with steam jacket to the outer cover of increaser, and described steam jacket one end flushes with described straight tube entrance, and the other end exports with described increaser and flushes formation vapor chamber; On described steam jacket end, symmetry is tangentially provided with at least one pair of steam inlet tube.
The temperature being entered the steam of heater by described steam inlet tube is 170 DEG C ~ 230 DEG C, and pressure is 0.8MPa ~ 2.8MPa, and flow is 8t/h ~ 20t/h.
The temperature of the place's hot water to be added entering heater by described water inlet pipe is 43 DEG C ~ 60 DEG C, and pressure is 0.4MPa ~ 2MPa, and flow is 315t/h ~ 500t/h.
The beneficial effects of the utility model are:
1, the utility model tangentially enters vapor chamber steam by least one pair of pipe be evenly distributed on outside steam jacket, rotary motion is produced in vapor chamber, steam is uniformly distributed in chamber, and the quantity of steam entered in straight tube and increaser by the steam hole on straight tube and increaser is equal at circumferencial direction;
2, the utility model makes water rotate under the effect of convergent static mixer and flaring static mixer, the water that tube hub density is large moves to the tube wall of straight tube and increaser under centrifugal action, the steam that density is little then moves in pipe, steam and water blending heat exchange in the process of mutually moving, steam condensation Cheng Shui, each surface again owing to surrounding vapor chamber does not comprise reducing pipe surface, like this, high-temperature steam would not and vapor chamber condensation reducing pipe outside low because of the water temperature in reducing pipe, reduce to greatest extent because steam-water mixing through aperture the phenomenon such as the vibration that produces and water hammer,
3, the direction of rotation of the utility model convergent static mixer and the generation of flaring static mixer is contrary with the direction of rotation of steam pipe generation, the total angular momentum equal and opposite in direction that the angular momentum that steam produces axis and convergent static mixer and flaring static mixer produce, direction is contrary, like this, whole steam-water injection just counteracts at the active force of radial direction by current and vapor stream, convergent static mixer opens the elementary rotary motion of current, and flaring blender maintains rotary motion and serves stepless action to blending heating effect.
