Description

Technical Field

[0001] The utility model relates to the technical field of liquid level detection, in particular to a balance container with a display structure. Background Art

[0002] In industry, the steam drum is an industrial equipment that can withstand the air pressure and water level pressure generated by the steam drum. The steam drum, also known as the boiler drum, is the most important pressure-bearing component in the natural circulation boiler and is mainly used in medium-pressure and high-pressure subcritical boilers in power production.

[0003] When used in drum applications, a liquid level detection device is required to detect the liquid level in the drum. Drum liquid level measurement must have two measuring devices with different working principles. The existing combined application method is a glass tube level gauge and a differential pressure transmitter, such as Figure 1 As shown, the upper part of the drum is connected to the upper negative pressure chamber of the double-chamber balancing container through a flange, and the lower part of the drum is connected to the vertical tubular positive pressure chamber in the double-chamber balancing container through a flange. The upper end of the positive pressure chamber is open, and the lower end of the positive pressure chamber is connected to the positive electrode of the differential pressure transmitter outside the double-chamber balancing container, and the bottom of the negative pressure chamber is connected to the negative electrode of the differential pressure transmitter; the upper end opening of the positive pressure chamber is flush with the liquid level of the negative pressure chamber, and the excess condensed water produced by the liquefaction of high-temperature steam in the upper end of the positive pressure chamber flows into the positive pressure chamber from the upper end opening of the positive pressure chamber. Due to the principle of the communicating vessel, the liquid level in the positive pressure chamber and the liquid level in the drum are always kept at the same height. The condensed water produced by the high-temperature steam is used at the vapor phase end of the balancing container to keep the liquid level constant as the negative electrode reference of the differential pressure transmitter, and the changing liquid phase end of the drum is connected to the positive electrode of the differential pressure transmitter and converted into a standard signal.

[0004] The glass tube level gauge outside the double-chamber balancing container displays the liquid level height of the positive pressure chamber, which is observed by the monitoring camera and the image is sent to the control center. The differential pressure transmitter converts it into liquid level difference through the balancing container and outputs this difference as a standard signal to the control center.

[0005] However, the existing liquid level detection equipment still has certain defects in practical application. The glass tube liquid level gauge requires a close distance to see the position of water in the glass tube clearly. Due to the reflection phenomenon of the glass tube, the image sent to the control center by the monitoring camera has poor clarity, which limits the observation of the liquid level and makes it impossible for the control center to accurately grasp the liquid level situation. In response to the above problems, we provide a balance container with a display structure to solve the above-mentioned problems. Utility Model Content
