Analysis of Application Trend of Spray Dustfall System

Dust hazards:

Dust is mainly produced during the process of raw material opening and processing. Due to the large dust generated during the processing, if dust is not matched with the corresponding dust removal system, dust will permeate the entire construction work area and the health of the human body. And the surrounding environment has caused some damage.

Dust Solid particles that can float in the air. Due to the special nature of the dust, the size of the particle size and other factors, it has great harm to the human body. Its chemical properties participate in and interfere with the degree and speed of biochemical processes in different degrees in the body. For example, toxic metal dust (mercury, manganese, cadmium, lead, etc.) enters the human body and can cause poisoning and even death.

After the general dust enters the human lungs, it may cause pneumoconiosis, such as silicon, asbestos, carbon black and so on. Dust also has a great influence on industrial production. It can reduce the product quality and machine work accuracy, and affect the visibility of the working environment. Some dust will explode under certain conditions. In addition, the discharge of dust in excess of the concentration into the atmosphere also causes environmental pollution. Therefore, dust removal is very necessary.

Furthermore, in the production work environment, the presence of workers is necessary, and due to the material crushing process, the shear-compressed dusting effect of the vibrating screen, and the movement of the material onto the belt to induce air dusting, in the workshop Dust is generated and suspended in the air or in the air, which greatly increases the danger of dust. In order to control the dust, reduce its hazards, and improve the work environment of the workshop, it is necessary to set up a dust removal system in the workshop for dust removal so that it can be discharged after reaching the discharge standard. The system has been used by a number of industrial and mining companies and has been fully affirmed and highly evaluated.

Spray dust system advantages:

1, the economy

Example of a 1000 square meter construction site

(1) One-time investment, used for many years. 50-200 yuan per square meter. 1,000 square meters investment 100,000 yuan.

(2) The operating cost is low and it takes 8 hours to work every day: the water consumption is 2 tons/day. Electricity costs about 5 kWh.

(3) The maintenance cost in the later period is low, and the filter water filter can be replaced regularly every month, and the cost per filter is only 10 yuan.

(4) It has strong versatility and can be installed in and outside the construction site and in the layout of the production line.

2, efficient

Spray dust system application scope:

(1) Dust removal and cooling in the dusty construction sites of power plants, port coal terminals, railway freight yards, mines, coal mines, iron and steel plants, and coal coke chemicals;

(2) Spray dust, spray dust and dust in large coal yards, coal yards, stockyards, raw material yards, ore yards, and transport trucks;

(3) Large-scale sterilization, deodorization, and sanitation prevention in waste dumps, public places, and after natural disasters.

(4) Humidification, cooling and disinfection of workshops and processing plants.

Spray dust system working principle:

When the diameter of water mist particles and dust particles are close to each other, the probability of adsorption, filtration, and condensation of the stroke is the largest. As long as the particles are generated from the microscopic water mist particles with the same size of the dust particles, they are adsorbed and adhere to each other and the aggregation increases. Settlement under the action of its own gravity can achieve the purpose of dust reduction.

When the water mist is formed, negative ions are generated, and a large number of positive ions in the dust are combined with the negative ions in the water mist, so that the dust quickly drops, the water mist and the dry dust are released, the humidity of the air is increased, and a large amount of latent heat of the air is absorbed, thereby playing well The cooling effect of water mist and dust generation technology is mainly focused on the size of water mist particles in the range of 1-50 microns. It has extremely strong dust-reducing effect on dust below 50 microns, so that inhalable dust particles can be controlled on the source of pollution to the human body. Harm, and meet the requirements of the EPA.
