Quarry is one of the major sources of dust pollution, because the stone in the crushing, screening, transportation process will produce a lot of dust, in order to avoid serious pollution to the regional environment, but also to ensure the health of the operators, it is necessary to adopt appropriate dust reduction solutions, dust pollution control quarry.
 
According to the nature of dust, treatment volume and emission standards, different treatment methods are selected. At present, the dust removal technology mainly includes electric dust removal, cloth bag dust removal, wet dust removal and cyclone dust removal. The dust generated by stone crushing has the characteristics of wide particle size distribution, easy moisture absorption, and high dust concentration in the collected gas. If the electric dust removal treatment is adopted, the first level treatment must be done, and the operation cost and difficulty are relatively large. The bag dust collector mainly collects dust by the way of "negative pressure dust collection". For the unorganized discharge of dust, such a negative pressure space is not easy to achieve. This is because the site environment is relatively open, can not reach the filter air volume required by the bag dust collector, and the field concentration is constantly changing, directly affect the pressure of the bag dust collector. When the pressure loss increases, excessive energy loss will be caused, and then the dust removal efficiency will be reduced. In addition, the bag dust collector covers a large area, the cloth bag is easy to wear, condensation, high operation and maintenance costs, resulting in "secondary pollution". The mechanism of cyclone dust removal is to make the dusty air flow rotate, with the help of centrifugal force to separate the dust particles from the air flow and collect them on the wall of the device, and then make the dust particles fall into the ash bucket with the help of gravity. Each component of the cyclone collector has a certain size proportion, and the change of each proportion relationship can affect the efficiency and pressure loss of the cyclone collector, among which the diameter of the cyclone collector, the size of the air inlet and the diameter of the exhaust pipe are the main influencing factors. When used, it should be noted that advantages can also be turned into disadvantages when a certain limit is exceeded. In addition, some factors are beneficial to improve the efficiency of dust removal, but will increase the pressure loss, so the adjustment of all factors must be taken into account, but cyclone dust removal is not suitable for the use of outdoor mines and the cost is high. Therefore, high pressure misting system is a more suitable dust removal equipment for quarry. high pressure misting system has low water consumption, high dust removal efficiency, low initial investment and operating costs, and good dust removal effect. The modular design technology can effectively control the source of dust pollution. Compared with the traditional cloth bag dust removal system, the equipment input is less, the area is smaller, the operation is convenient and there is no dust secondary pollution.
 
 

Is it necessary to misting, dust, humidify and cool the quarry?

 
Nowadays, many quarry leaders and employees have higher and higher requirements for the working environment of the quarry. Almost every year there are news reports, explosions and even casualties at the quarry. A considerable part of the quarry dust content is caused by high, so the quarry misting dust removal humidification cooling is a must!  
 
So, is there an effective method of misting, dust removal, humidification and cooling in quarry? In addition to preventing heat stroke, can it also achieve the effect of dust removal? The current popular misting methods (artificial fog, misting dust removal, humidification and cooling) can effectively solve such problems.
 

We summarized the following points, how to choose the right misting cooling system:

 
1. Selective use: When using artificial fog (misting dust removal, humidification and cooling system) system, the following aspects should be considered. Firstly, ventilation in the quarry is a problem and is not recommended for use in a fully enclosed area.
 
2. Secondly, it is not recommended to use in areas with very high humidity requirements, such as workshops with humidity ratio of about 10%-15%;
 
3. Again, do not use it around equipment that is sensitive to humidity.  

Misting dust removal, humidification and cooling

 
When using misting cooling system, it is necessary to consider the coverage area, calculate the misting amount, choose the right nozzle, comprehensive consideration of seasonal climate characteristics and other key issues; The control points of misting cooling system are arranged by reasonable layout and people-oriented.
 
At the same time, pay attention to the key points in the construction process, do not choose irregular construction units, so as to avoid accidents.
 
Please identify the various types of sprinkler heads available on the market. So as to avoid the adverse effects in the actual operation.
 
The above are some operational details of the quarry misting, dust removal, humidification and cooling.
