Specific embodiment
Referring to figs. 1 to Fig. 5, a kind of steam-water separation equipment in the present embodiment, the equipment includes a cylinder 10, in cylinder 10
Side wall be respectively symmetrically equipped with steam inlet 11 and steam (vapor) outlet 12, the lower part of cylinder 10 is fixedly mounted there are two support leg 14,
The fixation for realizing steam-water separation equipment is bolted in support leg 14 and anchoring piece 15.Carbonated drink point is formed inside cylinder 10
From cavity, it is fixedly installed with flow distributor and steam-water separator respectively in steam-water separation cavity, under the action of flow distributor, from steaming
The steam that vapour entrance 11 flows into uniformly enters steam-water separator after flow distributor, and steam-water separator includes two in upper and lower level point
The steam-water separation unit 23 of cloth, bracket 25 is inclined is fixed in steam-water separation cavity by fixed for steam-water separation unit 23, and
And connecting plate 24 is fixedly connected between two steam-water separation units 23.It is connected to the company at 23 head and the tail both ends of steam-water separation unit
Fishplate bar 24 effectively prevents steam and directly flows out from steam (vapor) outlet 12 around steam-water separation unit 23.Steam-water separation unit 23 inclines
It tiltedly places, effectively increases the contact area of steam Yu steam-water separation unit 23, improve the efficiency of steam-water separation.And carbonated drink
Separative unit 23 is in longitudinal layered arrangement, solves the problems, such as that single steam-water separation unit 23 is height-limited, meanwhile, use is this
Layered arrangement can mitigate the steam inlet and hydrophobic amount of each steam-water separation unit 23, ensure that each steam-water separation list
The reliability service of member 23.
Preferably, flow distributor includes the distribution duct 21 being connected with steam inlet 11 and is vertically provided at steam-water separation chamber
The steam output end of the port plate 22 of body, distribution duct 21 extends around in horn-like and forms an annular opening, flow
Plate 22 is divided into several flow regions from top to bottom, and flow region is equipped with equally distributed through-hole 225 and each flow region
225 diameter of through-hole is different.Steam output end in horn-like camber line be to be designed according to fluid mechanics principle, steam from
Steam inlet 11 is horizontal to flow into distribution duct 21, under the action of distribution duct 21, steam by water conservancy diversion in a perpendicular,
And it is spread by annular opening, can ensure that the lesser pressure loss and is evenly distributed for the first time around.In carbonated drink point
A port plate 22 between distribution duct 21 and steam-water separator vertically-mounted from the intracorporal upper and lower ends of chamber, port plate
22 to be divided into the region that four are evenly distributed with through-hole 225 from top to bottom be the first flow region 221, the second flow region 222, the
Three flow regions 223 and the 4th flow region 224, wherein 225 diameter of through-hole in the first flow region 221 is smaller, the second flow
225 diameter of through-hole in region 222 and third flow region 223 is gradually increased, and 225 diameter of through-hole in the 4th flow region 224 is most
It is small.Since the steam flowed out from distribution duct 21 is spread around in vertical plane, when steam diffuses to steam-water separation cavity
Top and bottom when, steam be changed to the right toward steam-water separation unit 23 direction spread, the first flow region of port plate 22
221 and the 4th steam flowing velocity corresponding to flow region 224 it is larger, therefore 225 diameter design of through-hole is smaller, in flow
Under the blocking of plate 22, steam continues to flow toward the second flow region 222 and third flow region 223, since steam is in gravity
Under effect, the 4th flow region 224 is matched less than the first flow region 221 toward second toward the steam that third flow region 223 is flowed
Flow the steam that region 222 is flowed, thus according to the size of steam flowing velocity and steam number each match finally has been determined
Flow the size cases of 225 diameter of through-hole in region.
Preferably, the bottom of steam-water separation unit 23 is equipped with the drain pipe 31 across steam-water separation cavity, drain pipe 31
