Abstract
The invention discloses a horizontally-arranged periodic blow-down flash tank which cannot cause washout to a shell body easily. The horizontally-arranged periodic blow-down flash tank is provided with a shell body, the top of the shell body is provided with a sewage inlet pipe, the opening in the top of the sewage inlet pipe is a boiler periodic blow-down inlet, a spraying energy dissipater is installed in the inner cavity of the shell body, an opening in the bottom of the sewage inlet pipe is communicated with an inlet of the spraying energy dissipater, and a secondary steam discharge outlet is formed in the top of the shell body. The spraying energy dissipater is provided with a spraying pipe, the opening in the bottom of the sewage inlet pipe is communicated with an opening in the top of the spraying pipe, and a plurality of spraying holes which are arrayed evenly are formed in the bottom of the spraying pipe. A steam-water separating device is installed on the upper portion of the inner cavity of the shell body, and the steam-water separating device is installed on the bottom of the secondary steam discharge outlet and is communicated with the secondary steam discharge outlet. High-temperature high-pressure boiler blow-down water enters the spraying energy dissipater through the sewage inlet pipe, the flow direction of sewage is changed through the spraying energy dissipater, direct washout of the high-temperature high-pressure boiler blow-down water to the shell body of equipment is avoided, and the service life of the equipment is prolonged.
Description
Technical field
The present invention relates to a kind of horizontally-arranged periodical blowdown flash vessel.
Background technology
Horizontally-arranged periodical blowdown flash vessel mainly is the equipment that the periodical blowdown water of boiler is carried out dilatation step-down, cooling, separated secondary steam.
Boiler blowdown water has the saturated water temperature (HTHP) under the operating pressure identical with boiler and the pressure thereof, need to use the periodical blowdown flash vessel that boiler periodical blowdown water is carried out volume-expanding pressure-reducing, lowers the temperature, isolates indirect steam and spent hot water, indirect steam and spent hot water are used as thermal source, the heat of recovery section boiler blow-off loss improves boiler efficiency.Conventional boiler blowdown water regularly enters blowdown system, the part sewer is vaporized into indirect steam immediately, after indirect steam carries out the carbonated drink separation through the container top steam-water separator, outlet through the top is drawn, the sewer that stays then by the level control valve discharging, easily causes erosion to apparatus casing.
Summary of the invention
Technical problem to be solved by this invention is: a kind of horizontally-arranged periodical blowdown flash vessel that housing is difficult for causing erosion is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of horizontally-arranged periodical blowdown flash vessel, has housing, case top is equipped with sewage water inlet pipe, the sewage water inlet pipe open top is boiler periodical blowdown water inlet, and housing bottom has Sewage outlet, and the housing inner chamber is equipped with the spray energy dissipator, the sewage water inlet pipe bottom opening communicates with the import of spray energy dissipator, and case top is provided with secondary vapour floss hole.
Described spray energy dissipator has shower, and the sewage water inlet pipe bottom opening communicates with the shower open top, and the shower bottom offers a plurality of evenly distributed spray apertures.
Described shower two ends are provided with the closure plate of sealing usefulness.
Described closure plate and shower welding are fixing.
Described shower is fixed by the fixing angle steel bracket support of inner walls.
Described housing inner chamber top is equipped with water separator, and water separator is installed in secondary vapour floss hole bottom and communicates with secondary vapour floss hole.
Described water separator comprises the wire mesh demister that supports cylindrical shell and be positioned at the support cylindrical shell.
The invention has the beneficial effects as follows: the boiler blowdown water of HTHP is after sewage water inlet pipe enters the spray energy dissipator, change the flow direction of sewer by the spray energy dissipator, avoid the direct erosion of HTHP sewer to apparatus casing, prolonged the service life of equipment.
Description of drawings
Fig. 1 is the structural representation of the horizontally-arranged periodical blowdown flash vessel of the present invention;
Among the figure: 1, housing, 2, sewage water inlet pipe, 3, shower, 4, water separator, 5, secondary vapour floss hole, 6, Sewage outlet.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1, a kind of horizontally-arranged periodical blowdown flash vessel, has housing 1, housing 1 top is equipped with sewage water inlet pipe 2, sewage water inlet pipe 2 open tops are boiler periodical blowdown water inlet, and housing 1 bottom has Sewage outlet 6, and housing 1 inner chamber is equipped with the spray energy dissipator, sewage water inlet pipe 2 bottom openings communicate with the import of spray energy dissipator, and housing 1 top is provided with secondary vapour floss hole 5.
The spray energy dissipator has shower 3, and sewage water inlet pipe 2 bottom openings communicate with shower 3 open tops, and shower 3 bottoms offer a plurality of evenly distributed spray apertures.Shower 3 two ends are provided with the closure plate of sealing usefulness.Closure plate and shower 3 welding are fixing.Shower 3 is fixed by the fixing angle steel bracket support of inner walls.
Sewage water inlet pipe 2 bottom openings communicate with shower 3 open tops, and shower 3 bottoms offer a plurality of evenly distributed spray apertures.The boiler blowdown water of HTHP is after sewage water inlet pipe enters shower, change the flow direction of sewer by shower, sewer is carried out large-area porous shunting, avoided the direct erosion of HTHP sewer to apparatus casing, prolonged the service life of equipment.
Secondary vapour floss hole 5 lower ends are provided with water separator 4 water separators 4 and comprise the wire mesh demister that supports cylindrical shell and be positioned at the support cylindrical shell.Wire mesh demister carries out carbonated drink separation to secondary vapour, and the support cylindrical shell is fixed wire mesh demister and secondary vapour is carried out water conservancy diversion.After the silk screen of droplets entrained and wire mesh demister collides in the secondary vapour, be accumulated into bigger drop, drop arrive greatly climbing power that the gravity that himself produces surpasses gas and surface tension of liquid with joint efforts the time, drop just separates to fall from silk screen, through having improved the steam quality of secondary vapour after the carbonated drink separation, secondary vapour is discharged from secondary vapour floss hole 5, is recovered utilization, has remarkable economic efficiency.
