Description
Technical field
The present invention relates to a kind of boiler blow-off wetting system, especially relate to a kind of continuous blowdown water by boiler and carry out dilatation step-down to carry out the continuous blowdown flash tank of steam separation.
Background technology
Boiler blow down flash device comprises regular unloading container and continuous blowdown flash tank, and continuous blowdown flash tank is discharged by stove water maximum for stove water salt concentration from drum continuously, to make the quality that stove water often keeps good, thus produces qualified steam.
During continuous blowdown flash tank work, sewer is entered by water inlet, current are pipe inspection tangentially, inwall formed moisture film rotate and under, due to centrifugal action, form the water membrane skirt of High Rotation Speed at mouth of pipe place, heated by the saturated vapor of packing layer bottom upwards ascension, the oxygen that is dissolved in the water and incondensable gas are overflowed in water, and the gland steam exhauster through the steam-water separator on end socket top enters air.The heat transfer coefficient of this equipment is higher, in the short period of time water can be heated to the state of requirement.
There is following defect in the continuous blowdown flash tank of prior art: on the one hand in use, there is level gauging inaccuracy, the coarse defect of pressure measxurement; On the other hand, water inlet current inject rear rotation and lower impact cylinder inboard wall, and cylindrical shell easily weares and teares, and cause the defect that product is not grown service life.
Summary of the invention
In order to overcome the defect of prior art, the object of this invention is to provide a kind of level gauging and pressure measxurement more accurately, the continuous blowdown flash tank of product longer service life.
In order to achieve the above object, the present invention adopts following technical scheme:
A kind of continuous blowdown flash tank, comprise vertical cylindrical shell, described cylindrical shell is provided with the sewer import and manhole with adapter, described cylindrical shell is also provided with liquid level emasuring device, thermometer and pressure samples pipe, described pressure samples pipe is provided with pressure gauge, it is characterized in that: the top of described sewer import is provided with top board, described top board is connected with the baffle plate to downward-extension, the both sides of described baffle plate are connected with the inwall of described cylindrical shell, described sewer import covers on wherein by described top board and described baffle plate completely, described sewer import is also provided with wearing plate with on the cylinder inboard wall of side-lower.
Preferably, described wearing plate at least covers 1/3rd of the inwall girth of described cylindrical shell below described sewer import in a circumferential direction.
More preferably, described wearing plate covers for symmetrical centre alignment bilateral symmetry extends with the vertical curve at the place, center of described sewer import.
More preferably, the top of described wearing plate is overlapping with the projection section of described baffle plate on described cylinder inboard wall.Adopt this structure, the water that sewer import can be made to spray directly is flushed on wearing plate by being back to after baffle after on inwall.
More preferably, described wearing plate in the vertical direction covers 2/3rds of the distance from described sewer import center to the low head junction of described cylindrical shell at least from top to bottom.
Further, described wearing plate is corrosion resistant plate.Adopt corrosion resistant plate as wearing plate, add wearability, further increase the service life of product.
Preferably, the cross section of described baffle plate is arc surfaced.
Preferably, described liquid level emasuring device is magnetic flap level gauge, described cylindrical shell is provided with level gauging mouth, lower level gauging mouth and is arranged on the measurement adapter of the upper and lower level gauging mouth of described cylinder Ligation in vitro, and described magnetic flap level gauge is installed in described measurement adapter.Magnetic flap level gauge has magneto-restrictive structure, and it is more clear to show, and more responsive to the minor variations of liquid level, therefore level gauging is more accurate.
Preferably, described pressure samples pipe is stainless steel tube.Adopt stainless steel tube to replace traditional carbon steel pipe as pressure samples pipe, solve because service time grown the problem of later internal corrosion Severe blockage by pressure samples pipe, thus avoid the inaccurate defect of consequent pressure measxurement.Use stainless steel tube as pressure samples pipe, pressure measxurement is more accurate.
Owing to adopting technique scheme, compared to prior art, a kind of continuous blowdown flash tank level gauging provided by the invention and pressure measxurement are more accurate, longer service life.

Fig. 2 is the top view of continuous blowdown flash tank of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is described in detail.
Refer to Fig. 1 and Fig. 2, the invention provides a kind of continuous blowdown flash tank, comprise vertical cylindrical shell 1, described cylindrical shell 1 is provided with the sewer import 2 and manhole 3 with adapter 21, described cylindrical shell 1 is also provided with liquid level emasuring device 4, thermometer 5 and pressure samples pipe 6, described pressure samples pipe 6 is provided with pressure gauge 7 and relief valve 8.In described cylindrical shell 1, top is provided with out vapour demister 11.
The top of described sewer import 2 is provided with top board 9, described top board 9 is connected with the baffle plate 10 to downward-extension, the both sides of described baffle plate 10 are connected with the inwall of described cylindrical shell 1, the cross section of described baffle plate 10 is arc surfaced, described sewer import 2 covers on wherein by described top board 9 and described baffle plate 10 completely, and described sewer import 2 is also provided with wearing plate 12 with on the cylinder inboard wall of side-lower.Wherein, described wearing plate 12 is corrosion resistant plate.Adopt corrosion resistant plate as wearing plate, add wearability, further increase the service life of product.
Described wearing plate 12 to cover 1/3rd of the inwall girth below described sewer import 2 with the vertical curve at the place, center of described sewer import 2 for symmetrical centre alignment bilateral symmetry extends.As described in Figure 2, wearing plate 12 is for overlapping the arc shape of cylindrical shell 1 inwall, and arc angle is 120 °.
The top of described wearing plate 12 is overlapping with the projection section of described baffle plate 10 on described cylindrical shell 1 inwall.Adopt this structure, the water that sewer import 2 can be made to spray is back to after on inwall after being stopped by baffle plate 10 and is directly flushed on wearing plate 12.
