Abstract
The utility model relates to a balance container installed both inside and outside a boiler steam bag. A condensing room is installed outside the boiler steam bag, a balance tank is installed in the boiler steam bag, a steam heating thermal insulation sleeve (2) is sheathed outside a condensate water part at the lower part of the condensing room, two ends of steam and condensing water ducts are respectively communicated with the condensing room and the balance tank, a water inlet of a positive pressure sampling pipe is communicated with the balance tank, a water inlet of a negative pressure sampling pipe is communicated with the boiler steam bag, and the water inlets of the condensate water ducts of the steam heating thermal insulation sleeve are communicated with the bottom of the steam heating thermal insulation sleeve. The advantages are as follows: as the balance container consists of two parts of the condensing room and the balance tank, the condensing room is arranged outside the steam bag and the balance tank is arranged inside the steam bag, the balance container not only has the respective advantages of a built-in balance container and an external balance container, but also overcomes the respective defects of the two. The sensitivity and accuracy for detecting the water level of the steam bag are high.
Description
Technical field
The utility model relates to boiler drum level instrumentation field, and more particularly it relates to the two horizontalization weighing apparatus of boiler-steam dome container.
Background technology
Steam water-level is one of most important parameter in boiler and the control system thereof.The boiler-steam dome equalizing reservoir is used for being used for detecting steam water-level with dipperstick or supporting the making of differential pressure transmitter.Existing equalizing reservoir has built-in equalizing reservoir (equalizing reservoir is arranged in the drum) and external equalizing reservoir (it is outer that equalizing reservoir is arranged at drum).Built-in equalizing reservoir weak point is: the water temperature of coagulating in the air chamber is lower than the water temperature in the compensator, and differ bigger, when the water in coagulating air chamber flows in the compensator, cause the variation of water temperature in the compensator, the density temperature influence of water changes in the compensator, thereby cause that pressure reduction changes on the differential pressure transmitter, indication produces fluctuation, and measurement brings error to liquid level.External equalizing reservoir weak point is: the malleation probe tube of external equalizing reservoir directly is connected with air chamber with fixed attention, water in the air chamber is directly as comparing water column with fixed attention, owing to be subjected to the influence of environment temperature, the water temperature of coagulating in the air chamber is more much lower than water temperature in the drum, and the water temperature of coagulating in the air chamber changes with the variation of the interior water temperature of drum inconsistent, the variable density that is to say the water in the air chamber with fixed attention is inconsistent with the variation of the interior water density of drum, thereby cause the differential pressure transmitter jitter, measure error is bigger than built-in equalizing reservoir.
The utility model content
The purpose of this utility model is exactly built-in equalizing reservoir and above-mentioned deficiency of external equalizing reservoir to be arranged and two horizontalizations containers that weigh are provided inside and outside a kind of boiler-steam dome at present existing equalizing reservoir.
The utility model is made of condensing chamber, Steam Heating muff, compensator, steam and the dual-purpose conduit of condensed water, negative pressure probe tube, malleation probe tube and Steam Heating muff condensing water tube; The condensing chamber is installed in outside the boiler-steam dome, compensator is installed in the boiler-steam dome, the Steam Heating muff is enclosed within outside the condensed water position of bottom, condensing chamber, the dual-purpose conduit of steam and condensed water two ends communicate with condensing chamber and compensator respectively, malleation probe tube water inlet communicates with compensator, negative pressure probe tube water inlet communicates with boiler-steam dome, and the water inlet of Steam Heating muff condensing water tube communicates with Steam Heating muff bottom.It also has standby malleation probe tube and standby malleation sampling pipe valve, and the water inlet of standby malleation probe tube communicates with the condensing chamber, and standby malleation sampling pipe valve is installed in standby getting on the forward voltage diode.
The utility model has the advantages that: because this equalizing reservoir is divided into condensing chamber and compensator two parts formation, and the condensing chamber places outside the drum, compensator places in the drum, promptly has built-in equalizing reservoir and external equalizing reservoir advantage separately, has overcome shortcoming separately again.Detect the highly sensitive of steam water-level, degree of accuracy height.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment
As shown in the figure, the inside and outside two horizontalization weighing apparatus containers of boiler-steam dome are made of the dual-purpose conduit 4 of condensing chamber 1, Steam Heating muff 2, compensator 3, steam and condensed water, negative pressure probe tube 5, malleation probe tube 6 and Steam Heating muff condensing water tube 9; Condensing chamber 1 is installed in outside the boiler-steam dome 10, compensator 3 is installed in the boiler-steam dome 10, Steam Heating muff 2 is enclosed within outside the condensed water position of 1 bottom, condensing chamber, the dual-purpose conduit of steam and condensed water 4 two ends communicate with condensing chamber 1 and compensator 3 respectively, malleation probe tube 6 water inlets communicate with compensator 3, negative pressure probe tube 5 water inlets communicate with boiler-steam dome 10, and the water inlet of Steam Heating muff condensing water tube 9 communicates with Steam Heating muff 2 bottoms.
It also has standby malleation probe tube 7 and standby malleation sampling pipe valve 8, and the water inlet of standby malleation probe tube 7 communicates with condensing chamber 1, and standby malleation sampling pipe valve 8 is installed on the standby malleation probe tube 7.Standby malleation probe tube is used for can directly getting malleation from standby malleation probe tube 7 after built-in compensator 3 damages, and effect is equivalent to external equalizing reservoir.
During use the negative pressure probe tube is communicated with differential pressure transmitter 11 with the malleation probe tube, (Chinese: collective and distributive type control system) 12 are connected differential pressure transmitter 11 with DCS.
Working method: the steam in the drum at first enters the condensing chamber from steam and the dual-purpose conduit of condensed water, deposits bottom, condensing chamber after the steam condensation in, flows into the usefulness of compensator for the malleation probe tube through steam and the dual-purpose conduit of condensed water again.The effect of Steam Heating muff is condensed water water temperature that it can make the condensing chamber more near the water temperature in the drum, thereby helps improving the sensitivity and the degree of accuracy that detects steam water-level.
