Description
Technical field
The present invention relates to a kind of boiler blow-off wetting system, especially relate to a kind of periodical blowdown water by boiler and carry out dilatation step-down to carry out the regular unloading container of steam separation.
Background technology
Boiler blow down flash device comprises regular unloading container and continuous blowdown flash tank, and the operation principle that regular unloading container is is that the periodical blowdown water of boiler is carried out dilatation step-down, isolates steam, is used, and improves the heat-economy of power plant.
There is following defect in the regular unloading container 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 regular unloading container of product longer service life.
In order to achieve the above object, the present invention adopts following technical scheme:
A kind of regular unloading container, it is characterized in that: comprise horizontal cylindrical shell, two ends, described cylindrical shell left and right are connected with end socket, described cylindrical shell upper end is provided with the sewer import and row's atmospheric outlet with adapter near the side of left end end socket, described cylindrical shell is also provided with manhole, liquid level emasuring device, thermometer and pressure samples pipe, described pressure samples pipe is provided with pressure gauge, and the cylinder inboard wall below described sewer import is provided with wearing plate.
Preferably, described wearing plate at least covers 2/3rds of described cylinder inboard wall girth in a circumferential direction.
Preferably, described wearing plate is corrosion resistant plate.Adopt corrosion resistant plate as wearing plate, add wearability, further increase the service life of product.
Preferably, described liquid level emasuring device is magnetic flap level gauge.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.
Preferably, the inherent described row's atmospheric outlet place of described cylindrical shell is also provided with exhaust screen device.Adopt exhaust screen device, can prevent steam from flinging out outside row's atmospheric outlet.
More preferably, described exhaust screen device comprises cylindric gas outlet, and the barrel of described gas outlet is provided with multiple through hole, and described gas outlet upper end communicates with described row's atmospheric outlet, and its lower end is coated with barrier plate.
More preferably, described multiple through hole is same apertures and is uniformly distributed.
More preferably, described barrier plate is the downward opening coniform plate that is connected concentric on described gas outlet.
Preferably, described manhole is arranged at the bottom of described left end end socket.Manhole is arranged at the bottom of end socket, is convenient to maintenance and the maintenance of equipment.
Owing to adopting technique scheme, compared to prior art, a kind of regular unloading container level gauging provided by the invention and pressure measxurement are more accurate, longer service life, and are convenient to maintenance and safeguard.In further improvement of the present invention, by the pressure samples pipe adopting magnetic turnover plate type liquid level gauge and stainless steel tube to make, make level gauging and pressure measxurement more accurate; By manhole being arranged on the bottom of end socket, facilitate maintenance and the maintenance of equipment; By arranging exhaust screen device on row's atmospheric outlet, prevent steam from flinging out outside row's atmospheric outlet.
