The upper and lower ends of the same side of the chuck, wherein, the air inlet pipe and the water inlet pipe inside the chuck with connecting.
In order to further improve the practicality of salt hydratable salt water- to-water heat exchanger, the air inlet hole number at least one, uniformly
It is distributed on the tube wall of the central tube between the water inlet pipe and the air inlet pipe, and with the central axis of the central tube
Centered on circular array be distributed, the air admission hole is through hole.
In order to further improve the practicality of salt hydratable salt water- to-water heat exchanger, the impact-absorbing shell is hemispherical shell, its quantity
There are two, respectively on the tube wall of the central tube inside the chuck, wherein, the impact-absorbing shell bottom offers installation
Hole, the mounting hole are through hole, and its aperture is equal with the external diameter of the central tube, and the impact-absorbing shell is fixed by the mounting hole
It is enclosed on the central tube.
Beneficial effect is：The primary brine salt dissolving water- to-water heat exchanger relatively has the advantage that with former plate type heat exchanger：
1st, stability：1. pipeline mixer will not often be unpicked and washed because debris blocks, the stabilization of production is kept；2. pass through through
Test outlet temperature before a certain amount of normal temperature supplement water of opening ensures logical steam and be less than 60 degree, it is ensured that logical steam steady in a long-term is not
With switching often, ensure the stability of technic index.
2nd, economy：1. steam is directly mixed in all energy of salt dissolving water and do not wasted, and plate type heat exchanger generation steam is cold
Lime set is discharged, and is recovered energy even if water and is also wasted significantly；2. duct type does not have the resistance drop of plate type heat exchanger, conveying can be reduced
The power electric of pump about 15%.3. will not block up without often unpicking and washing, labour cost is safeguarded in saving.4. obstructed circulating water, reduce
The consumption of recirculated water.5. equipment cost is small, without with circulating water line, without with condensate liquid recovery pipe, main equipment cost
It is small.
3rd, simple operation：1. the execute-in-place without often switching steam circulation water.2. take up an area small.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As Figure 1-Figure 2, primary brine salt dissolving water- to-water heat exchanger, including central tube 1, the outer cover of central tube 1 are provided with chuck
2, the side of chuck 2 is provided with water inlet pipe 3 and air inlet pipe 4, and air inlet pipe 4 is used for steam and entered in chuck 2, and water inlet pipe 3 is used to supplement
Water enters in chuck 2, and air admission hole 5 and impact-absorbing shell 6, the steam that air admission hole 5 is used in chuck 2 are additionally provided with the tube wall of central tube 1
Enter central tube 1 with supplement water, impact-absorbing shell 6 enters chuck 2 for buffering air inlet pipe 4 into the steam in chuck 2 and water inlet pipe 3
Interior supplement water, in use, because technological requirement salt dissolving water outlet temperature is stable at 60 degree.Therefore, when salt dissolving water by after, if
Temperature is less than 60 degree, and low-pressure steam is entered in the impact-absorbing shell 6 of the upper steam buffering area of chuck 2 by regulating valve from air inlet pipe 4, is steamed
Vapour presses down liquid level in chuck 2, and liquid level can be adjusted to ensure that steam leads to because of pressure effect needed for above and below the size of vapour amount
