Abstract
The utility model discloses a steam drum water level double-room container, and the structure comprises a steam side sampling tube, a heating room connected with the steam drum, a water side sampling tube and a sampling room connected with the steam drum. The sampling room is inserted with a flow guiding device. For the sampling tube is made by a corrugated tube, the contact area of the sampling room and the heating room is enlarged, and the water level in the sampling room is close to the water level of the steam drum. For the installation of a liquid level measuring instrument such as the flow guiding device and sonar, the measured data is more accurate.
Description
Technical field:
The utility model relates to the two chambers of a kind of steam water-level container, is the boiler drum water level measurement device.Belong to the boiler auxiliary products.
Background technology:
Under safe operation of the boiler required, the level measuring of boiler-steam dome just becomes a very important operational factor of industry spot to be measured, and the level measuring of boiler-steam dome does not all have good measurement mechanism both at home and abroad always.Existing steam water-level meter such as mica water level gauge, electric contact point fluviograph, level switch all are to adopt the single chamber of side load siphunculus measuring principle to measure tube.These measuring equipments just adopt simple connecting pipe principle, utilize the transparency of mica or the electric conductivity of water and steam to observe or measure water level then.Shortcoming is: its heat-insulating property is bad when measuring equipment is worked, heat radiation easily, water temperature in the measuring equipment descends, its density increased thereupon after water temperature descended, water level in communicating pipe will be lower than the water level in the boiler-steam dome, its value is subjected to the influence of drum pressure and environment temperature factor, has uncertainty; The differential pressure water level gauge that also has a kind of equalizing reservoir in addition, this water level gauge is that the pressure differential of water in drum water and the equalizing reservoir is guided in the differential pressure transmitter by instrumentation pipeline, the output electric signal of differential pressure transmitter is guided in the secondary instrument again by showing after pressure, the temperature compensation correction, its shortcoming is to measure steam water-level indirectly by differential pressure, intermediate link is many, error is big, system reliability is poor, causes the error of measurement very big.
Content of the present utility model:
The purpose of this utility model provides a kind of heating chamber and is connected with drum by vapour side stopple coupon, the two chambers of the steam water-level container that the sampling hut is connected with drum by lateral water sampling tube.
The purpose of this utility model is achieved by the following technical solution: the two chambers of a kind of steam water-level container, it is characterized in that heating chamber passes through vapour side stopple coupon and is connected with drum, fluid level measuring instrument is installed in sealing on the upper end cover of heating chamber, the drainpipe that the downtake that the bottom welding is connected with drum is communicated with, interior welds support bar at heating chamber, its other end is fixed with the sampling hut made from corrugated tube, insert in the sampling hut by mozzle, condenser, diversion trench, the guiding device that fair water cone is formed, fair water cone be welded on heating chamber on cover, condenser is welded on the heating chamber, the sampling hut passes on left lateral water sampling tube and is connected with drum, and downside is installed blow-off pipe.The connectivity points of drainpipe and downtake is under the center line of drum below 15 meters.Fluid level measuring instrument can be selected sonar, ultrasound wave, laser, level switch etc. for use.
Advantage of the present utility model:
1, because corrugated tube is made by sampling hut 4, can increase the contact area of saturated steam in sampling hut 4 and the heating chamber 5, make that to add thermal effect better.With saturated vapour the water in the corrugated tube 4 is heated, make its temperature keep with drum in the saturation water temperature approaching, reduce because the water level deviations that the water-mass density difference causes, make in the sampling hut water level more near the water level in the drum.
2, because the guiding device of fair water cone 9, condenser 7, diversion trench 8, mozzle 6 compositions is installed above sampling hut 4, make the condensate water of saturated vapor above heating chamber can import different aspects in the corrugated tube 4 smoothly, the water of different aspects in the corrugated tube 4 is heated; Can also reduce the fluctuation of the saturation water liquid level in the corrugated tube 4, it is more accurate to measure.
3, owing to adopt drainpipe 10 to be connected with the downtake of drum 13, and connectivity points is selected in following 15 meters of drum center line, guarantee that the condensate water saturated vapour is emitted heat of vaporization in heating chamber 5 after causes downtake by drainpipe 10, and guarantee that water level can not rise to bringing-up section and reduce heating surface (area) (HS in the drainpipe.
4, owing to adopt fluid level measuring instruments 3 such as sonar, ultrasound wave, laser, level switch, make measurement more accurate.
