What equipment is needed to control dust at construction sites?

Multi-functional dust suppression vehicle, fog cannon machine, dry fog dust suppression device, high-pressure car washing machine, windproof dust suppression net, etc.

1. The multi-functional dust suppression spraying vehicle belongs to the coal loading point spraying dust suppression curing agent.

One of the installations, mainly serving railways, roads and other fields. When the train transports coal, the dust suppression vehicle can solidify the coal on each train, forming a protective film and reducing pollution.

2. When transporting coal and mineral powder by train and car, dust suppressant can be sprayed on the bulk materials on each car to form a protective film and reduce pollution. It is widely used in the process of transportation of other bulk materials to prevent dust pollution, as well as slag yards, coal storage yards, construction sites, automobile coal dust, sand fixation, steel building materials, cement, and ecological slope protection of various open-air material yards of enterprises.

3. The dust suppression vehicle mainly uses the hydraulic system.

Interaction with electronic control systems.

That is, the mobile spraying equipment injects the spraying liquid into the storage tank at the liquid distribution station and goes to the spraying point by itself; When the train passes, the photoelectric detection system begins to identify the traction locomotive, and after the traction locomotive passes, a signal is issued, and the controller controls the transmission hydraulic system to rotate the liquid distribution pipe and the carriage orthogonally, and starts the liquid pump to start spraying at the same time.

Fourth, the fog cannon machine adopts horizontal 360° free rotation and vertical -10° 45° up and down pitch adjustment functions, 360° full coverage, no dead angle spraying, to ensure that there is no dead angle in the whole process of dust removal. Trouble-free work with an average of 8000 hours of spraying, highly intelligent, simple operation and easy maintenance. This product can be moved or fixed in one place, and can be used in a wide range of applications.

Fifth, the fog cannon machine in actual use, the spray of water mist like a drizzle drifting with the wind, floating on the face like a layer of sweat, will not spray wet clothes, will not be on the ground "and mud", the finer the water mist, but the easier it is to absorb fine particles.

And it consumes less water per hour, which is more water-saving than sprinkler trucks.

6. The micron-level dry mist dust suppression device can produce water mist particles with a diameter of 1-10 microns, and effectively adsorb and coalesce the dust suspended in the air-——especially the inhalable dust particles with a diameter of less than 5 microns, and settle by gravity, so as to achieve dust suppression.

7. The high-pressure car washing machine integrates high-pressure micro-water cleaning, high-power vacuuming, and ozone disinfection.

Tire inflation, polishing and waxing, dry cleaning in the car, cross-river dragon ignition, LED strong lighting 8 functions in one, energy saving and environmental protection, water and electricity saving, charging once, power consumption of a few tenths of a degree, can wash twenty or thirty cars, can work continuously, atomization is stable. The adjustable nozzle is washable and flushable.

The dust suppression fog cannon machine is suitable for dust control work in a variety of occasions, including steel plants, coal chemical plants, power plants, construction sites, coal mining enterprises, garbage disposal sites, park squares, urban roads, etc., the dust generated by these fields will seriously affect people's normal production and life.

The dust suppression fog cannon machine uses the fine water mist sprayed by the principle of high pressure, adheres to the dust particles in the air, and descends to the ground after reaching a certain weight to achieve the purpose of dust reduction.

Generally speaking, when customers choose a fog cannon machine, the factors that need to be considered are: dust control occasions, dust pollution degree, fog cannon machine style, whether the fog cannon machine needs a more durable stainless steel fog cannon machine, budget and so on.

Considering the above factors, customers can look for it, make comprehensive comparisons, consider comprehensively, and conduct field visits to select suitable fog cannons.

Dust control measures for building construction

With the rapid development of urban construction, the number of construction sites in various places is increasing rapidly, and the dust caused by all aspects of construction has become an important factor leading to air pollution. With the in-depth development of the blue sky defense war, strengthening the prevention and control of dust pollution at construction sites has become an important task of urban environmental governance.

In view of some difficulties encountered by the regulatory authorities in the prevention and control of dust on construction sites, five suggestions are shared, hoping to improve the problem of dust pollution on construction sites.

The construction site supervision department should combine daily publicity and education, explain the dust prevention and control measures and standards of the construction site to the enterprise, inform the relevant responsible entities of the basis and amount of administrative penalties that will be imposed for violating the relevant provisions of dust control, and guide them to consciously perform their dust prevention and control responsibilities.

The construction site supervision departments should strictly set the construction fence, main road hardening, cleaning facilities, enclosure spray, whether to install monitoring and networking as required, whether to install license plate identification and barrier facilities, whether there is a prevention plan and special prevention and control funds as a precondition for the approval of construction permits. If the hardware facilities for dust prevention and control do not meet the requirements, they will not be approved and construction will not be allowed.

Construction sites and construction, construction, supervision and other units that are ineffective in the prevention and control of dust pollution shall be strictly managed and severely punished. For those who do not carry out rectification in accordance with the requirements or fail to rectify within the time limit, they shall be ordered to stop work for rectification in accordance with the law, and in accordance with the relevant provisions of the relevant provisions of the bad behavior shall be included in the muck disposal credit management system, and the circumstances shall be circulated and criticized, filed for investigation and punishment, and shall be carried out through the first and foremost, and shall be linked to market access, awards, qualification promotions, bidding, etc.

The dust prevention and control work at construction sites involves not only different regulatory departments, but also construction units, construction units, and supervision units. In order to improve the effect of dust pollution prevention and control on the construction site, it is necessary to define the regulatory responsibilities and territorial management responsibilities of the departments of construction, municipal, transportation, and construction headquarters in the prevention and control of dust at the construction site in accordance with the principle of "who is responsible for the jurisdiction, who approves and supervises, and who pollutes and prevents and controls", and strives to realize that each department performs its own duties and cooperates with each other.

1.Dust control for transport vehicles.

Construction transport vehicles, excavation machinery, etc. must be removed from the construction site for dust-proof treatment, and it is strictly forbidden to take the soil and dust out of the construction site. The sedimentation tank is cleaned regularly, generally once every 2 or 3 days.

2.Control of dust pollution from building materials.

Set up a special pool tank for sand and gravel to be stacked to control the number of feeding, so that it can be used at any time and not hoarded in large quantities. When stacking, the pile should be square, the feet should be neat and clean, and the perimeter and the top should be flattened and compacted, and then covered with a dense mesh cover.

If the sand and gravel is too dry, it should be sprinkled in time. Other fly-prone objects and fine bulk materials must be tightly covered or stored in an airtight warehouse, and the transport vehicles should be protected from leakage and flying, and centralized stacking measures should be taken when unloading to reduce pollution. If it is piled up in the construction site for more than 48 hours, it should be stored in a closed manner or covered with a net or membrane in time to prevent wind erosion dust and water erosion migration.

3.Control of dust pollution from construction waste.

The construction waste (exposed garbage) in the building structure floor is sprinkled with water and moistened before cleaning, and the transportation can be transported by setting up a closed special garbage channel or using sealed containers and bags, and special personnel are sent to inspect and supervise.

It is strictly forbidden to throw it in the air, and the garbage collected by the cleaning is stacked in the site planning site, and an appropriate amount of water is sprinkled or covered with dense mesh, and the garbage is removed from the site regularly to reduce dust pollution.

4.Control of dust pollution from household waste.

Arrange special personnel to collect and clean up domestic garbage, and stack it separately from construction waste at the designated location, and carry out airtight shielding. Domestic garbage should be removed by the sanitation department in a timely manner. It is forbidden to burn construction waste, waste wood, plastic products and hot melt asphalt on site to prevent pollution to the atmosphere.

Dust monitoring equipment is installed to monitor and control the dust concentration at the construction site. When the dust concentration reaches the upper limit set, the fog cannon machine or spray equipment will be linked to spray the site. It can achieve the control of dust.

You can choose the dust monitoring equipment of Shandong Renke Measurement and Control, which can view the dust data on site and remotely view the dust data in real time. It can achieve the effect of prevention.

First, the soil is covered second, the road surface is hardened, and third, the temporary operation area is sprinkled.

It is an on-site civilized construction plan.

Due to the work of mechanical equipment, a large amount of dust will be generated in the construction site, which will seriously affect the quality of the surrounding environment and the working environment of the on-site staff.

It is an effective method to use fog cannon machine to reduce dust and use the principle of high pressure to spray dust reduction. Fog cannon machine rotary spray, pitch spray, which expands the scope of dust control, water mist dust reduction belongs to physical dust reduction, has little impact on the environment, and can also beautify the environment and moisten the air.

Generally speaking, mobile fog cannon machines or fog cannon trucks are mostly used for dust reduction in construction sites, which can be moved to reduce dust and are also convenient to use.

Dust protection measures. 1. Cement, ash, sand and other materials stacked in the construction site that are prone to dust pollution.

2. Within 30 days after the completion of the project, level the construction site and remove the accumulated soil and piles.

3. Do not use air compressors to clean the dust of vehicles, equipment and materials.

4. The ground of the construction site is hardened. Sprinkle water frequently where there is dust.

5. Set up a hard airtight enclosure of not less than 2 meters around the construction site.

6. If the construction waste and engineering residue cannot be cleared and transported within 48 hours, a temporary stacking yard shall be set up in the construction site, and the temporary stacking yard shall take dust-proof measures such as fencing and covering.

10. If bulk materials, construction waste and muck are transported on the building, they shall be cleared and transported in a closed manner, and they shall not be thrown or scattered in the air.
