Abstract
The utility model discloses a multi-operating mode intelligent boiler drum water level gauge with high validity. The multi-operating mode intelligent boiler drum water level gauge with the high validity comprises an auxiliary measuring metal communicating vessel communicated with the boiler drum and further comprises a camera, wherein the lens of the camera faces to the metal communicating vessel, and the camera is connected with a processing module. By means of said technical scheme, the camera shoots the water level in the metal communicating vessel through a glass window on the metal communicating vessel, the data processing module decodes and analyzes the water level and converts the water height in the metal communicating vessel into a signal frequently used by the intelligent boiler drum water level gauge and used for a DCS to measure and control the water level of the boiler drum. The signal of the camera can be transmitted to a monitoring display screen through a video line, and a fireman observes the signal through the monitoring display screen. According to the working principle of the multi-operating mode intelligent boiler drum water level gauge with the high validity, the water height is shot directly, the measuring step is less, and the measuring is not influenced by the temperature, pressure and others in the boiler drum; compared with the prior art, the multi-operating mode intelligent boiler drum water level gauge with the high validity has higher precision and validity and is suitable for various working conditions.
Description
Technical field
The utility model relates to Industrial Boiler drum level measurement field, specifically relates to a kind of multi-state intelligent boiler steam water-level meter of high validity.
Background technology
Boiler drum level meter is the essential level transmitting instrument of the normal operation of boiler, and the Intelligent boiler steam water-level meter that present stage can teletransmission mainly contains three kinds.The one, equalizing reservoir formula boiler drum level meter, equalizing reservoir divides two kinds, single-compartment balance container and two chambers equalizing reservoir, but its to be all detection based on pressure determine steam water-level.The 2nd, electric contact type boiler drum level meter, utilizes the feature of water conduction in drum, by load onto contact on the cylinder of UNICOM's boiler-steam dome, measures height of water level, and because electric contact is subject to the impact of physical size, resolution is lower, is not easy for automatic control system.The 3rd, condenser type boiler drum level meter, this structure is generally ganged condenser structure, and there is insulating sleeve centre, and the height difference that water enters two electrodes causes electric capacitance change, by Detection capacitance amount, determines height of water level.This detection method is owing to being subject to temperature, and the impact of the specific inductive capacity of medium own, can cause measuring drift etc., now mostly be optimized to the ganged condenser of multi-segment structure, utilize the electric capacitance change of each section mutually to compensate, reduce temperature, the impact that the variations such as medium specific inductive capacity bring.The method requires very high to interelectrode dielectric strength.Above three kinds respectively have relative merits, and its principle is the variable quantity that the variation of water in drum causes other non-water level, by calculating, is converted to water level again.Owing to there is high temperature, high pressure, saturated vapour and the situations such as other material for preventing that in drum, fouling is added in boiler-steam dome, make said method be difficult to measure effectively, accurately actual height of water level.Its principle of work is other amount calculating conversion and gets water level simultaneously, therefore true not.
Summary of the invention
The purpose of this utility model is to provide a kind of multi-state intelligent boiler liquid level of steam drum meter of high validity, effectively solves high temperature in drum, high pressure, saturated vapour and the impact for preventing that situations such as other material that in drum, fouling is added from bringing.
For achieving the above object, the utility model is by the following technical solutions:
A multi-state intelligent boiler steam water-level meter for high validity, it comprises the metal linker of the subsidiary being connected with boiler-steam dome; It also comprises camera, and the camera lens of camera is towards metal linker, and described camera is connected with processing module.
Described metal linker is the metallic cavity being communicated with boiler-steam dome, has view window in metallic cavity.
Described metallic cavity one end is connected with vapour phase mouth, and the other end is connected with liquid phase mouth.
Described view window is located at the one-sided or bilateral of metallic cavity.
Described camera is positioned at the dead ahead of metal linker view window, or is located at top, below and the side of metal linker view window.
Described metallic cavity is tubular or tabular.
It also comprises light source, and light source is towards metal linker.
At metal linker, light shield is set outward, light source and camera are arranged on light shield.
Described light source is visible ray or infrared ray, is positioned at the side of camera side or bilateral glass window.
Adopt the utility model of technique scheme, the windowpane seeing through on metal linker by camera photographs the water level in metal linker, then by data processing module, decode, analyze, water residing height in metal linker changes into signal that intelligent boiler liquid level of steam drum meter is conventional for DCS the most at last, finally realizes measurement and the control of boiler drum level.The signal of camera can pass to monitoring display screen by video line simultaneously, for fireman, observes.Because principle of work of the present invention is directly to take the height of water, measurement links is few, not affected by temperature in boiler-steam dome, pressure etc., and more existing other technology has higher precision, validity, applicable to various working environment.
