Balance container system capable of online setting and checking and online setting and checking method

Abstract

The invention relates to a balance container system capable of online setting and verification and an online setting and verification method thereof. The system includes a balance container and a balance container respectively connected to a steam drum space and a water space through a steam connecting pipe and a water connecting pipe. The connected differential pressure transmitter and the differential pressure transmitter are also connected to the boiler control system; the upper part of the balance container cylinder is vertically provided with a water supply pipe and a vent pipe, and the water connecting pipe is vertically provided with a water correction pipe through a tee, and the water supply The setting height of the lower end surface of the pipe is the upper limit position of water level detection, and the setting height of the upper end surface of the water calibration pipe is the lower limit position of water level detection. The system is simple in structure, easy to use and adjust, and can realize the online setting and checking of the balance vessel without disassembly; its online setting and checking methods are divided into three adjustment methods: manual setting at the initial installation of the boiler, manual compensation setting during operation, and automatic compensation setting. The setting is fast and effective, which can ensure the stable and reliable working performance of the balance vessel, and can greatly save the setting and verification time of the balance vessel.

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
