Safe and efficient dedusting, cooling and fire extinguishing multifunctional system

Abstract

The invention discloses a safe and efficient dedusting, cooling and fire extinguishing multifunctional system, and belongs to the technical field of spraying dedusting, cooling and fire extinguishing. According to the system, through combination of a dust concentration sensor, a temperature sensor and an infrared sensor, three functions of dedusting, cooling and fire extinguishing are achieved. A PLC automatic control system is arranged in an automatic equipment controller of the safe and efficient dedusting, cooling and fire extinguishing multifunctional system, the dedusting, cooling and fire extinguishing full-automatic process is achieved, safety of a worker is ensured, and waste of water is effectively reduced. A magnetic device is adopted, generated magnetic water can improve the surface tension of water and prolong the existing time of spray droplets in the airflow, and through magnetic water spraying, the dust surface hydrophilic property can be improved, and the contact and coagulation condition of water mist and dust can be improved; and a circular cooling device is adopted, in the spraying dedusting and fire extinguishing process, the temperature of the surrounding is reduced, and the fire extinguishing efficiency is further improved.

Description

technical field [0001] The invention belongs to the technical field of dust removal, temperature reduction and fire extinguishing equipment, and in particular relates to a safe and efficient dust removal, temperature reduction and fire extinguishing multifunctional system. Background technique [0002] With the rapid development of modern industry, industrial dust pollution has become the bottleneck of safe production and environmental protection. The main characteristics of dust are small particle size and light weight, while industrial dust has a large surface area and a strong ability to absorb air. Usually an air film is formed. Therefore, industrial dust is not easy to land and can be suspended in the air for a long time. Dust with a diameter greater than 10 μm accelerates down in still air and quickly falls to the floor; dust with a diameter of 0.1-10 μm falls at a constant speed; dust particles with a diameter of less than 0.1 μm basically do not fall. Due to the in...

AI Technical Summary

Problems solved by technology

[0004] 1. Poor atomization effect: Traditional spray dust removal and cooling facilities are difficult to ensure the stability of water pressure. Too high or too low water pressure will have a great impact on the atomization effect

[0005] 2. Large water consumption: Traditional spray dedusting and cooling facilities cannot realize the automatic control of the whole process of start-stop spraying, and due to the low dust-reduction efficiency, it takes a long time to spray, so water resources are often wasted

[0006] 3. Inconvenient communication: In the manual remote control spraying process, the communication between operators is inconvenient,

[0007] 4. It is difficult to reduce respirable dust: due to the poor atomization effect, the ability of water mist to capture respirable dust is reduced, which will cause a large amount of respirable dust residue

[0009] 1. It will produce harmful gas: some fire extinguishing agents will have a chain reaction with the burning material while extinguishing the fire to produce harmful gas

[0010] 2. Pollution of the environment: some fire extinguishing methods will produce some substances that pollute the environment after extinguishing the fire

[0011] 3. Low fire extinguishing efficiency: Some fire extinguishing technologies have poor suppression ability and long reaction time, which cannot completely prevent the fire from re-igniting
