Abstract
The utility model discloses a built-in type balancing container for a boiler. A built-in condensing water cup is arranged in a steam bag. One end of a steam guiding pipe is placed on the condensing water cup. The other end of the steam guiding pipe is communicated with an external balancing container through a one-time valve. A water injection cup is arranged on the external balancing container. The bottom end of the external balancing container is communicated with a differential pressure transmitter through an external balancing container pressure guiding pipe. The bottom end of the built-in condensing water cup is communicated with a water cup pressure guiding pipe and the external balancing container pressure guiding pipe through a first valve. A third valve is arranged on the external balancing container pressure guiding pipe. A steam bag water level pressure guiding pipe is communicated between the steam bag and the differential pressure transmitter and is provided with a second valve. A pressure equalizer is arranged on one end, placed in the steam bag, of the steam bag water level pressure guiding pipe. The differential pressure transmitter is connected with a DCS. According to the built-in type balancing container for the boiler, the built-in condensing water cup and the external balancing container can be switched freely through the valves, the shortcoming that when the built-in type balancing container operates, fault happens, and maintaining cannot be achieved is overcome, when fault happens in a built-in part during operation, the built-in part can be immediately switched to the external balancing container to monitor the water level continuously, and urgency blowing out maintaining is of no need.
Description
Technical field
The utility model relates to the built-in equalizing reservoir that a kind of boiler is used.
Background technology
Existing boiler all is to use built-in equalizing reservoir to carry out detection and the monitoring of water level, when operation, if built-in equalizing reservoir breaks down, because built-in equalizing reservoir is positioned at drum, and can't overhaul, and can't continue to monitor water level.Need shutdown maintenance.
Summary of the invention
The purpose of this utility model provides the built-in equalizing reservoir that a kind of boiler is used, built-in condensation water tumbler of the present utility model and external equalizing reservoir can switch arbitrarily by valve, solved the drawback that built-in equalizing reservoir breaks down and can't overhaul when operation, when built-in part breaks down in the running, can switch to external equalizing reservoir at once and continue to monitor water level.
Built-in condensation water tumbler of the present utility model is installed in the drum, one end of steam guiding tube is positioned at the condensation water tumbler, the other end of steam guiding tube is communicated with external equalizing reservoir by a valve, has the water filling cup on the external equalizing reservoir, the bottom of external equalizing reservoir is communicated with differential pressure transmitter by external equalizing reservoir connecting pipe, the bottom of built-in condensation water tumbler is communicated with external equalizing reservoir connecting pipe by the first valve and water tumbler connecting pipe, has the 3rd valve on the external equalizing reservoir connecting pipe, the steam water-level connecting pipe is communicated with between drum and differential pressure transmitter, has the second valve on the steam water-level connecting pipe, the end that the steam water-level connecting pipe is positioned at drum has voltage balancer, and differential pressure transmitter connects with the DCS system.On the described built-in condensation water tumbler top cover is installed.
The course of work of the present utility model and principle are:
The water tumbler connecting pipe of comparing water column connects differential pressure transmitter from middle the passing of water side joint pipe, level pressure in the drum is drawn by the steam water-level connecting pipe from water side joint base and is connect differential pressure transmitter, built-in condensation water tumbler upper end is equipped with top cover, can prevent vapor flow and drowning to the impact in the built-in condensed water cup, guarantee the stable of comparing water column, built-in condensation water tumbler in the drum links to each other with external equalizing reservoir by vapour side steam guiding tube simultaneously, the condensate return that external equalizing reservoir produces is in the interior built-in condensation water tumbler of drum, make built-in condensation water tumbler be in all the time full state, the assurance comparing water column is highly stable, external equalizing reservoir is provided with the water filling cup, can in the external horizontalization weighing apparatus container water filling of use initial stage, external equalizing reservoir be come into operation fast.Front end at lateral water sampling tube is equipped with voltage balancer, and the liquid level that can eliminate in the drum fluctuates on the impact of water level suddenly.
The beneficial effects of the utility model:
Comparing water column of the present utility model is installed in inside steam drum, thereby make the density of water in the density of comparing water column and the drum identical, when initial operating stage and normal operation, all can obtain stable comparing water column simultaneously, so in playing stove and running, all can monitor accurately water level.Built-in condensation water tumbler of the present utility model and external equalizing reservoir can switch arbitrarily by valve, solved the drawback that built-in equalizing reservoir breaks down and can't overhaul when operation, when built-in part breaks down in the running, can switch to external equalizing reservoir at once and continue to monitor water level, use urgent shutdown maintenance.
