What are the effective dust explosion protection measures for explosion-proof dust removal equipment?


1. Anti-explosion measures for storage structure design of industrial dust collectors


When designing the silo workshop, consider the problem of dust explosion and try to keep the silo lane away from the office area and living area. The distance should not be less than 30m. In the workshop less than 150m, the number of workers is no more than 10, and two security can be set up. For export, the width of the evacuation stairway is not less than 1.1m, the width of the corridor is not less than 1.4m, and the width of the evacuation door is not less than 0.9m. Each storehouse roof shall be provided with an independent manhole and air replacement device, and shall not be connected to each other. The main dust-producing workshop shall be Set venting device, manhole not less than 800 × 800mm.


2. Reduce production and dust points and control environmental dust concentration


For dust-producing or dust-raising posts in the process of storage and transportation, dust production and dust raising points should be reduced, dust diffusion should be controlled, and the dust concentration in the surrounding space should be reduced so that the dust concentration does not exceed 10 mg/m3. We controlled the dust concentration far beyond the explosion limit. Naturally, it will control the occurrence of dust explosions.


3。 The main explosion-proof measures taken from the electrical selection and layout of the production process equipment


The principle is rational process design, correct selection, normal maintenance, observing the operating procedures, controlling and eliminating the fire source, preventing friction heat, impact ignition, eliminating ignition and explosion locations, simplifying the process flow, avoiding multiple upgrades, and using explosion-proof buckets Lifting machine, equipment should have a reliable grounding, with automatic alarm, automatic parking and other protection devices, design and manufacture of storage and transportation equipment should consider removable or easy maintenance. At the same time, consideration should be given to the proper operation of ventilation dust removal and explosion protection systems. From the production equipment, it is necessary to select electric appliances that meet the requirements of the National Electric Law, and have dust-proof and explosion-proof equipment, reduce the linear speed of hoisting machines and other conveyors, reduce the damage, install permanent magnets on the raw grain conveyors, and remove metal from the grain.
