Problems solved by technology

The disadvantages of this patent are: 1. The microwave source and the transmitter circuit board are integrated together. When a component fails, it needs to be replaced as a whole, and the cost ratio is high. Considering economics, it is not practical
2. This patented equipment only detects the concentration of pulverized coal, and cannot detect and deal with abnormal conditions such as pipe blockage during operation in a timely manner. It has a single limitation and only provides indicative parameters with few functions.

Abstract

The invention relates to a coal powder concentration monitoring device, in particular to a microwave concentration online measurement system. It includes an installation kit, a sensor kit, a meter head, an electric valve and a proximity switch. The installation kit includes a base and a base seal. The base is installed on the powder pipe to be tested. A microwave radar is installed inside the sensor suite, the sensor suite is located on the base seal and fixed with a base screw cap, the meter head is located at the upper end of the sensor suite, and an intelligent transmitter and an intelligent transmitter are installed in the meter head. Display terminal. The invention adopts the independent design of the three parts of the installation base, the microwave radar and the transmitter circuit, and the spare parts of each part can be replaced independently. Manually / automatically handle pipe blockage and other conditions to achieve the purpose of stabilizing furnace conditions, protecting spray guns, and improving coal injection efficiency.

Description

Technical field [0001] The invention relates to a pulverized coal concentration monitoring device, in particular to a microwave concentration online measurement system. Background technique [0002] The concentration and fluidity of pulverized coal in the powder feeding pipe of the combustion system are very important parameters, which directly affect the uniformity of the powder feeding, the stability of the combustion system and the combustion efficiency. Therefore, it is of great significance to study the pulverized coal concentration measurement technology and find a suitable method for pulverized coal concentration measurement. [0003] Patent No. 2010203017425, a microwave method for blast furnace coal injection on-line monitoring device, including a shell, the inside of the shell is fixed with a circuit board, the bottom of the circuit board is connected with a microwave source transmitter and receiver, the bottom of the shell is fixed with a base, and the lower part of the ...
