Technical Field

The invention relates to the field of energy conservation and environmental protection, in particular to a monitoring system of an energy-saving multiphase flow self-circulation dust suppression and removal device.

Background

At present, the main aspects of pollution in China comprise air pollution, water pollution and noise pollution, and industrial dust belongs to one of particulate matters of air pollution. The national safety production industry standard AQ4202-2008 'management Standard for air-breathing coal dust contact concentration in workplace' stipulates that the management Standard for the air-breathing coal dust contact concentration in workplace is 5.0mg/m³However, controlling the dust concentration under the standard value in the related industries is still a bottleneck problem faced by many enterprises. If the industrial dust concentration exceeds the standard, occupational respiratory diseases of people can be caused, explosion is generated, and heavy loss of personnel and equipment is caused. Therefore, effective control is adopted in the generation, transmission and accumulation processes of the industrial dust, and the strengthening of the prevention and control of the industrial dust is an important task.

The current mainstream dust removal methods such as filtration type dust removal, electric dust removal, wet type dust removal and the like all have a common problem: the dust removal process entails high energy consumption. Therefore, in view of high efficiency, economy, energy conservation and emission reduction, a new dust suppression and removal theory and application are provided, and the dust suppression and removal theory and application utilize the negative pressure phenomenon generated in the material blanking process to absorb the generated raised dust according to the multiphase coupling principle so as to realize self-circulation dust removal without external power. However, this energy-conserving self-loopa presses down dirt dust collector and relies on the structure, and is required higher to the sealed degree of inside, and high sealed degree just can't observe the condition of inside, especially to the monitoring of inside all kinds of data, like the wind pressure of dust, the temperature of dust when different regions, for guaranteeing that the device can normal operating, need synchronous observation device running state and each item monitoring data in the dust removal process to can in time stop the apparatus when data are unusual, avoid producing the passageway and block up. Meanwhile, the formed data also needs to be fed back to the return pipe, and the size of the data is controlled through the opening degree of the return pipe, so that dust suppression and dust removal are realized in a targeted manner. The opening degree of the existing return pipe cannot be well controlled due to the sealing requirement.
