Description
Technical Field
The utility model relates to a temperature control device for a gas pipeline.
Background
In the field of industrial production, the mass flow of gas needs to be strictly controlled, and in commonly used flowmeters, the flow measurement value of such as an orifice plate flowmeter, a laminar flow mass flowmeter, a turbine flowmeter, a vortex shedding flowmeter, an electromagnetic flowmeter, a rotameter, an ultrasonic flowmeter, an elliptic gear flowmeter and the like is the volume flow of fluid. The amount of fluid involved in scientific research, process control, quality management, economic accounting, and trade delivery activities is generally mass. Measuring only the volumetric flow rate of a fluid using such a flow meter often fails to meet human requirements and it is often desirable to try to obtain a mass flow rate of the fluid. In the past, the quality of the fluid can only be indirectly obtained through correction, conversion, compensation and other methods after measuring parameters such as temperature, pressure, density, volume and the like of the fluid. The measuring method has a plurality of intermediate links, and the accuracy of mass flow measurement is difficult to ensure and improve. With the development of modern science and technology, several metering methods and devices for directly measuring mass flow rate are developed in succession, so that the progress of the flow measurement technology is promoted.
The fluid, when flowing in a rotating tube, generates a force on the tube wall, which is found by coriolis in 1832 when studying the turbine, simply called coriolis force. In 1977, the first mass flowmeter in the world was developed by the creator of the united states high-level (Micro Motion) company according to this principle. The mass flowmeter is based on Coriolis force, two parallel flow tubes are arranged in the sensor, a driving coil is arranged in the middle of the sensor, detection coils are arranged at the two ends of the sensor, when excitation voltage provided by a transmitter is applied to the driving coil, the vibrating tubes vibrate in a reciprocating cycle, fluid media in an industrial process flow through the vibrating tubes of the sensor, coriolis force effect is generated on the vibrating tubes, the two vibrating tubes vibrate in a torsion mode, two groups of signals with different phases are generated by the detection coils arranged at the two ends of the vibrating tubes, and the phase difference of the two signals is in proportional relation with the mass flow of fluid flowing through the sensor. The computer calculates the mass flow through the vibrating tube. When different media flow through the sensor, the main vibration frequencies of the vibration tube are different, and the density of the media is calculated according to the main vibration frequencies. The platinum resistor mounted on the sensor vibrating tube can indirectly measure the temperature of the medium.
The mass flowmeter directly measures the mass flow of the medium through the flowmeter, and can also measure the density of the medium and indirectly measure the temperature of the medium. Because the transmitter is an intelligent instrument taking the singlechip as a core, more than ten parameters can be derived for users to use according to the three basic quantities. The mass flowmeter has flexible configuration, powerful functions and high cost performance, and is one new generation of flow meter.
In the field of solar cell production, an MFC gas mass flowmeter is used for controlling gas mass flow in the process of coating and diffusion, and as the requirements on coating and diffusion are more and more strict, the gas mass flow control is more and more required, and in this case, the influence of temperature on the gas mass flow is more and more great. At present, the temperature of nitrogen and oxygen has been tracked, so that the influence on the accuracy of the MFC gas mass flowmeter for diffusion is large, and further the process control parameters are influenced, so that the semi-finished product is poor.
