What are the functions of construction site spray dust reduction equipment?

The dust mist gun uses the principle of high pressure to spray water in the form of a fine water mist and deliver it to the place where the dust rises and floats. The fine water mist adheres to the dust particles in the air, and the moist particles continue to adhere to it, so that the particles with a certain weight fall to the ground under the action of gravity, so as to achieve the purpose of dust reduction.

The types of dust and fog cannons include fixed dust and fog cannons, mobile dust and fog cannons, tower dust and fog cannons, multi-functional dust suppression vehicles, etc. There are many dust fog guns used in general construction sites, such as mobile dust fog guns, multi-functional dust suppression vehicles, etc.

The gun of the multi-functional dust suppression vehicle can spray fine water mist, and its bottom nozzle can also spray fine water mist near the ground. However, the multi-functional dust suppression vehicle is large in size and small in flexibility, and is suitable for large-scale construction sites.

Bian Xiao of Huali Electromechanical learned that at the project site of Country Garden Tianqin Garden in Zhengzhou, Henan, there are several dust reduction fog guns to prepare for spraying water mist and controlling dust.

Then the leadership put forward three requirements for the construction project:

The first is to speed up the progress of construction. It is necessary to clarify the time node and make every effort to do a good job in earthwork removal at the construction site.

The second is to strengthen service guarantees. The office should work closely with the project unit to track the whole process and promote cooperation.

Third, do a good job in dust control and management on the construction site. Intensify continuous management, reasonably set up fog cannon machines, external spray systems and other equipment, and fight the battle of atmospheric dust reduction.

For small construction sites, mobile dust collector fog guns can show great power.

forest protection, urban landscaping, street trees and other tall trees spraying to control pests and diseases;

There is no difference in the name of the same equipment, for example, Mandarin eats, Cantonese says food, the same meaning, I am doing waste gas treatment equipment.

Large, there will be water and puddles on the ground, suitable for heavy dust and not afraid of water, which has basically been eliminated. Spray dust reduction uses a high-pressure plunger pump to pressurize, and then cooperate with the fogging and dust reduction nozzle to produce micro-mist particles, which float in the air, the size is close to dust, and it is easy to adsorb dust on the ground without producing stagnant water, which is suitable for most factories. Now environmental protection promotion of several sprays to reduce dust, after the installation of spray, but also to transform, down the cost is higher.

Hello, spray dust removal spray out of water particles, spray dust removal fog particles are different in nature, the traditional method of dust removal we all know that the use of tap water to solve the dust problem, is the use of water droplets in the process of evaporation and dust particles in the air combined, the specific gravity increases, and then land. As we all know, in the process of coal mining, drainage is a very important problem, and the accumulation of water in the channel can easily cause accidents such as collapse. However, the artificial fogging system has changed this situation, because the water particles produced are very small, extremely easy to evaporate, combine with the dust particles in the air, and then settle, but do not form stagnant water, artificial fog is an ultra-fine fog particles suspended in the air, and the fog contains a large number of negative ions.

It can increase the oxygen content of the air and greatly improve the environment in which people live and relax.

It is for dust protection.

Under the action of a certain water pressure, the water mist nozzle splits the water flow into water droplets less than 1mm, and the water droplets can absorb the dust of the construction site.

If cultural relics or ancient tombs are found during the construction, they should be properly protected, and should be reported to the relevant local departments in time before the construction can be continued. If permanent stakes for surveying or long-term observation points set up by geological and ** departments are found, they should be protected.

When laying earthwork construction in the section with above-ground or underground pipelines and cables, the written consent of the relevant management departments should be obtained in advance, and measures should be taken during the construction to prevent damage to the pipelines, prevent landslides, and avoid serious accidents caused by excavation.

When excavating earthworks, it is necessary to prevent subsidence and deformation of adjacent buildings or structures, roads, pipelines, etc. If necessary, it should consult with the design unit or construction unit, take protective measures, and observe the settlement or displacement during construction.

There will be a large amount of construction dust and secondary pollution during the use of the construction site, and the environmental department has requirements for the prevention and control of the construction site.

Spray dust reduction is one of the dust reduction methods, it is the use of high-pressure plunger pump to increase the tap water to 50kg-60kg pressure, the pressurized water through the high-pressure resistant conveying pipeline by the high-pressure atomization nozzle atomization to atomize it, the production of micro-mist particles, the diameter of the droplets is about 10-20 m, so that it can quickly absorb heat from the air, complete gasification and diffusion, attach the condensation of suspended dust in the air, so that it falls to the ground, so as to achieve the purpose of spray dust removal and air purification.

High-pressure spray tung dust reduction equipment is an environmental protection equipment that uses high-pressure water mist to condense dust particles and settle them to the ground. It has a good effect, which can effectively reduce dust pollution in industry, transportation and other fields, improve air quality, and protect people's health.

However, there are some disadvantages of high-pressure spray dust suppression equipment, such as:

High cost: The initial investment of high-pressure spray dust reduction equipment is large, and it is necessary to purchase high-pressure pumps, nozzles and other equipment, and install and maintain them, which is difficult for some small enterprises or rural areas to bear.

High energy consumption: High-pressure spray dust reduction equipment needs to use high-pressure pumps to raise the water pressure to a certain extent, which will consume a lot of electricity and increase production costs.

Limited scope of application: Since the high-pressure spray dust reduction equipment relies on water mist to condense particles, it is only suitable for some coagulable particles, and the effect is not good for some non-condensable or chemical particles.

High operational requirements: High-pressure spray dust suppression equipment requires professionals to operate and maintain, which is difficult to achieve for some enterprises that lack technical personnel.

To sum up, although high-pressure spray dust reduction equipment can reduce dust pollution in the air to a certain extent, it also has some of the above disadvantages and needs to be comprehensively considered.

The watering map of the green belt is shown in the first bush.

The above are the main functions of the spray dust reduction truck.

The principle of dust suppression sprayer:

1) Under normal circumstances, the manpower-driven sprayer relies on hydraulic power, that is, hydraulic pressure, and pumps the liquid out through hydraulic pressure.

2) The pneumatic sprayer relies on the action of air flow to spray, and can carry out low and micro spraying. Compared with the hydraulic sprayer, the uniformity of the droplets is better, and the droplets are smaller, and the drift or targeted spraying can be carried out.

Spray dust reduction technology is a very common technology, the use is also very extensive, Guangdong Fenghua environmental protection equipment has a lot of the use of spray dust reduction technology to work, spray dust reduction is a new type of dust reduction technology, the principle is the use of spray particles due to its very small, the surface tension is basically zero, sprayed into the air can quickly adsorb various sizes of dust particles in the air, the formation of effective dust control.

3) Centrifugal sprayer is a spraying instrument that uses the centrifugal force when the centrifugal nozzle rotates at high speed to disperse or atomize the liquid medicine. The size of the sprayed droplets is relatively uniform, the droplet diameter is adjustable, the centrifugal nozzle speed is high, and the droplets are small. It can spray pesticides with high viscosity.

Can be used for both ultra-low volume sprays and low volume sprays.
