Bag type dust remover monitoring and diagnosis analysis system

Abstract

The invention discloses a bag type dust remover monitoring and diagnosis analysis system. The bag type dust remover monitoring and diagnosis analysis system includes monitoring hardware at a dust remover end, data acquisition equipment and a master computer; the monitoring hardware at the dust remover end includes a high-precision dust meter, a pressure transmitter and a differential pressure transmitter; the high-precision dust meter is installed on the position of an outlet pipe of a dust remover, a pressure tapping point of the differential pressure transmitter is installed in an inlet andoutlet of the dust remover, and the pressure transmitter is installed on a main output pipe of a gas storage tank; the data acquisition equipment is connected with the master computer, the data acquisition equipment includes a data acquisition cabinet which is internally provided with a PLC and a switch power supply, the data acquisition cabinet is connected with the PLC in an electric control cabinet of the dust remover in the field through a programming software, a switch and a network cable, and the data are synchronized and processed; and the programming software acquires the data of PLC in the data acquisition equipment through a protocol and the network cable. According to the bag type dust remover monitoring and diagnosis analysis system, the bag leakage judgment of a dust remover filtration system, the diagnosis of a lifting valve and a pulse valve of main components of a dust remover jet system, and the overall performance and multi-parameter evaluation analysis of the dust remover are realized.

Description

technical field [0001] The invention relates to a monitoring and diagnosis analysis system, in particular to a bag type dust collector monitoring and diagnosis analysis system. Background technique [0002] The bag filter is a dry dust filter device. After the filter material is used for a period of time, a layer of dust accumulates on the surface of the filter bag due to effects such as screening, collision, retention, diffusion, and static electricity. This layer of dust is called the first layer. During the subsequent movement, the first layer becomes The main filter layer of the filter material depends on the effect of the first layer, and the filter material with a larger mesh can also obtain a higher filtering effect. With the accumulation of dust on the surface of the filter material, the effect and resistance of the dust collector will increase correspondingly. When the pressure difference on both sides of the filter material is very large, some tiny dust particles ...

AI Technical Summary

Problems solved by technology

Since there are hundreds of pulse valves in a large dust collector, the site environment is noisy, and the pulse sound is high-pitched, which can easily lead to tinnitus. Generally, manual judgment methods cannot determine whether the pulse valve has leaked.

Conclusion: The diagnostic function of the pulse valve cannot be realized, and the real-time performance is poor
