Balance container system capable of performing online setting check and online setting check method based on balance container system

Abstract

The invention relates to a balance container system capable of performing online setting check and an online setting check method based on the balance container system. The system comprises a balance container and a differential pressure transmitter connected with the balance container, wherein the balance container is connected with steam space and water space of a steam dome through a steam connection pipe and a water connection pipe respectively, and the differential pressure transmitter is connected with a boiler control system; a water supplementing pipe and an emptying pipe are vertically arranged at the upper part of a balance container barrel, the water connection pipe is vertically downwards provided with a water check pipe through a tee joint, the lower end surface of the water supplementing pipe is set as high as the water level detection upper limit position, and the upper end surface of the water check pipe is set as high as the water level detection lower limit position. The system is simple in structure and convenient to use and adjust, and can realize non-dismantling online setting check of the balance container; the online setting check method based on the balance container system comprises three adjusting modes including manual setting during initial assembly of a boiler, manual compensation setting during operation and automatic compensation setting, the setting is rapid and effective, stable and reliable working performance of the balance container can be guaranteed, and the time for setting check of the balance container can be greatly saved.

Description

technical field [0001] The invention relates to a remote monitoring water level system used in steam boilers or heat exchange evaporators in the fields of metallurgy, coking, kilns, etc., in particular to a balance container system capable of online setting and checking and an online setting and checking method thereof. Background technique [0002] A steam boiler is a common heat exchange device and a special pressure vessel used to produce saturated steam or superheated steam. Its main heating medium is water, and the heating medium can use various heat sources, and various waste heat resources can also be used. Waste heat boilers are widely used in waste heat recovery of low-temperature flue gas and low-temperature water sources at kiln tails in metallurgy, coking, kilns and other industries. [0003] In the production and application of the waste heat boiler, in order to ensure the normal working state of the boiler, the intermediate water level in the drum (or steam dr...

AI Technical Summary

Problems solved by technology

[0007] Limited by the structure of the conventional dual-chamber balance vessel, once a problem occurs during boiler thermal adjustment and the accurate signal cannot be detected, it is necessary to stop the boiler or dismantle the balance vessel for readjustment; this wastes manpower and affects commissioning and acceptance schedule
