Steam drum water level built-in balance container device

Abstract

The invention relates to the technical field of detection equipment, and particularly relates to a steam drum water level built-in balance container device. The steam drum water level built-in balancecontainer device measures the water level in a steam drum body, can effectively avoid the influence of factors such as environmental factors, uncertain reference water level temperature in a positivepressure sampling tube and insufficient saturation of boiler water in a steam drum on a measurement result, effectively improves the measurement precision, facilitates the protection of equipment, effectively prolongs the service life of the equipment, and improves the practicability and reliability. The steam drum water level built-in balance container device comprises the steam drum body, a balance tank, a steam side tube, a condensation tank, a differential pressure transmitter, a negative side sampling tube, the positive pressure sampling tube and a DCS detector, wherein the balance tankis positioned inside the steam drum body, and a cavity is formed inside the balance tank.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a steam drum water level built-in balance container device. Background technique [0002] As we all know, whether the water level in the drum furnace is within the normal range is an important safety indicator for detecting the operation of the drum furnace. If the water level is too high or fluctuates sharply, it will cause the quality of the steam to deteriorate and carry water, resulting in salt formation on the heating surface. The downpipe carries steam, which affects the working conditions of the boiler water circulation, causing large-scale blasting of the furnace tube; the measurement error of the steam drum water level is large, which is prone to protection misoperation and refusal accidents, which may easily lead to accidents of boiler full water and water shortage. The existing detection methods mainly It is detected by external differential pressure water...

Problems solved by technology

If the water level is too high or fluctuates sharply, it will cause the quality of the steam to deteriorate and carry water, resulting in salt formation on the heating surface. The downpipe carries steam, which affects the working conditions of the boiler water circulation, causing large-scale blasting of the furnace tube; the measurement error of the steam drum water level is large, which is prone to protection misoperation and refusal accidents, which may easily lead to accidents of boiler full water and water shortage. The existing detection methods mainly It is detected by external differential pressure water level gauge, capacitive water level gauge and mica water level gauge. The measurement results are easily affected by factors such as environmental factors, uncertain reference water level temperature, and undersaturated boiler water in the steam drum, resulting in measurement errors. Larger, the device is easily damaged
