Description

technical field [0001] The invention relates to the technical field of metal dust collection and safe production, in particular to a wet-process integrated machine based on online monitoring of key safety parameters and efficient design of dust collection efficiency and an evaluation method thereof. Background technique [0002] There are a large number of polishing and grinding scenes in the processing and manufacturing industries of metal aluminum, magnesium and zinc, and a large number of micro-nano dust particles will be generated during the production process. Proper dust collection methods can also lead to dust explosion accidents and possible secondary gas explosion accidents. At present, the collection methods for combustible and explosive metal dust generally include dry centralized dust removal equipment, wet centralized dust removal device and wet integrated machine. Judging from the current application situation, because metal dust has low ignition energy and ig...

AI Technical Summary

Problems solved by technology

Judging from the current application situation, because metal dust has low ignition energy and ignition temperature, it has high sensitivity, so dry centralized dust removal equipment is basically not suitable for collecting metal dust, which has a greater risk of explosion; For the wet-type centralized dust removal device, due to the existence of long collection pipes that require explosion-proof treatment such as explosion-proof and spark extinguishing, the technical difficulty is relatively low and the reliability is low. Wet dust deposits are easy to accumulate heat and spontaneously ignite or react to generate hydrogen, and there is a greater risk of fire and explosion; for the wet-process integrated machine, due to its characteristics of dispersed collection and wet-process dust removal, its installation, use, and maintenance 1. Cleaning is very convenient, and it is difficult to form explosive conditions in the equipment. The intrinsic safety level is obviously higher than the above two centralized dust removal systems. However, some wet-process integrated machines currently exist have many disadvantages and greater risks. Specifically, It mainly includes the following aspects

[0003] First, there is a lack of standard specifications for product design and manufacturing, and there is no corresponding technical basis, quantitative indicators and methods to check and accept, such as dust capture efficiency, circulating water and noise indicators without specific experimental testing methods and data support, resulting in although the factory documents The relevant parameter values ​​in the system are relatively high, but they do not match the actual operation

This aspect mainly includes the design of high-efficiency wet dust removal method, the simulation of equipment airflow organization mode, and the comparison between various design indicators and the actual factory; the second is that the equipment lacks systematic safety monitoring measures, for example, most equipment does not have hydrogen detection. devices, or inaccurate test methods, resulting in extremely low service life of the testing equipment. At the same time, there are major defects in heat accumulation monitoring and other aspects, which have not been calculated and designed. Certain requirements, the existing products basically fail to meet the national requirements for online digitalization of relevant key parameters of the industry, and relevant environmental protection manufacturers have a relatively shallow understanding of safety requirements
