Problems solved by technology

[0003] Regarding the above solution, the applicant believes that there are still the following deficiencies: when replenishing water to the water level transmitter, the water level in the steam drum needs to be raised to a predetermined point, and then the water in the steam drum needs to be discharged to the normal liquid level. This method not only wastes water, but also needs to improve work efficiency

Embodiment 1

[0037] refer to figure 1 and figure 2 , is a kind of rapid steam drum water level meter replenishment device disclosed in the present application, comprising a first pipeline 1, the first pipeline 1 in this embodiment is selected as the inlet pipeline of the condensate preheater; The water replenishment main pipe 4 is connected with the replenishment water header 5, which is made of 316 stainless steel. After the condensed water flows out of the boiler, it can enter the replenishment water header 5, so as to realize the reuse of the condensed water. The connection between the water supply header 5 and the water supply main channel 4 is welded. At the same time, two first control valves 41 are installed on the water supply main channel 4. The first control valve 41 is a high-pressure valve, and the inlet and outlet of the first control valve 41 are connected to the water supply channel. The main pipes 4 are all welded. An air discharge pipeline is arranged on the top wall of...

Embodiment 2

[0043] refer to image 3 and Figure 4 , the overall structure of this embodiment is basically the same as that of the first embodiment above, the difference lies in the coil tube 9 and the heat exchange mechanism 91 .

[0044] refer to Figure 4 and Figure 5 At the same time, considering that the condensed water has a higher temperature when it flows out of the boiler, the condensed water with a higher temperature will cause pressure changes in the pipeline and the water supply header 5, which will affect the detection of the pressure in the steam drum 2 by the water level transmitter 3, Therefore, several coil pipes 9 are arranged in the water supply header 5, and the coil pipes 9 are coiled on the inner wall of the water supply header 5, and cooling liquid is arranged in the coil pipes 9, and the coil pipe 9 is located at the outside end of the water supply header 5 and communicates with Circulation pump 916 that drives coolant circulation, refer to Figure 6 A heat ex...

Abstract

The invention relates to a rapid steam pocket water level gauge water supplementing device which comprises a first pipeline, a steam pocket and a water level transmitter, the water level transmitter is communicated with a positive pressure side pipeline and a negative pressure side pipeline, the positive pressure side pipeline and the negative pressure side pipeline are communicated with the steampocket, and the first pipeline is communicated with a water supplementing main pipe. The water supplementing main pipe is communicated with a water supplementing header, the water supplementing header is communicated with a water supplementing pipeline, the water supplementing pipe is provided with a plurality of second control valves, the water supplementing pipeline is communicated with the positive pressure side pipeline, and a balance pipeline is communicated between the positive pressure side pipeline and the negative pressure side pipeline; a balance valve is arranged on the balance pipeline, a balance hole is formed in the tail end of the positive pressure side pipeline, and third control valves are arranged on the positive pressure side pipeline and the negative pressure side pipeline. The water supplementing device has the effects of improving the water supplementing efficiency and saving water resources.

Description

technical field [0001] The present application relates to the technical field of steam drum water level gauges, in particular to a fast water replenishment device for steam drum water level gauges. Background technique [0002] Drum water level is a very important monitoring parameter in steel boilers. It indirectly reflects the material balance relationship between boiler load and water supply. At present, the measurement principle of steam drum differential pressure water level transmitter with external single balance container is mostly used. When the unit is started in a cold state, in order to detect the water level of the air bubbles, it is necessary to ensure that the water level transmitter can accurately measure the liquid level in the steam drum. Until the preset point is exceeded, then the positive pressure side exhaust air calibration of the transmitter is performed, and the water in the steam drum is discharged to the normal liquid level after the calibration is...
