Engineering construction dust removal tool - spraying machine

Some environmental experts pointed out that most of the dust in the air now comes from construction sites. (Respirable particulate matter is dust and it is in most cases the primary pollutant of air quality.) Building dust is the main source of dust. Especially in recent years, the construction of cities around the country has been accelerating, and the number of large and small projects across the country has led to an increase in the proportion of building dust, accounting for the bulk of all types of dust, and the number has risen. Seriously affect the quality of the local air and endanger our healthy life.

What harm do dust have on the human body?

1, the local effect, that is, on the skin, cornea, mucous membranes and other local stimuli, resulting in a series of lesions.

2, poisoning effect, that is, inhalation of toxic dust, can be dissolved in the bronchial and alveolar wall after absorption, causing poisoning.

Occupational respiratory diseases, including pneumoconiosis, dust deposition, and respiratory cancer.

According to statistics, the use of cement in construction dust and its associated total dust emissions account for 35% of the total amount of construction dust. It can be said that the dust emission during cement use is the main source of pollution for construction dust. So how to solve the cement pollution in construction? Today Xiao Bian gave us a brief introduction of the dust spray equipment commonly used on 3 construction sites.

KSP series wet sprayer

KSP-9 concrete wet sprayer is mainly used in iron (public) tunnel engineering. The equipment is easy to operate, low dust, less rebound, protection of the environment, and improve the quality of the spray layer, a special vibration hopper so that the concrete can smoothly enter the batching system, the standard metering pump can accurately add accelerator, low pressure and low speed vortex flow delivery, The working principle of short-distance injection overcomes problems such as blockage, pulse, segregation, etc. The spray stream is even and stable. Improve spray material.

KBS-8A Pumped Wet Sprayer

Performance characteristics

1. High work efficiency: Adopting full hydraulic pumping design, system reliability can be greatly improved.

2, spray distance: the maximum level of 200 meters, 80 meters vertically. (4 times the jet distance of traditional equipment)

3, the injection volume is continuously adjustable. (continuously variable speed)

4. The amount of quick-setting agent added can be adjusted within the scope of 0 to 9%.

5. Low consumption of equipment accessories: The service life of main wearing parts is not lower than 3000m3 (It is 10 times of the service life of the wearing parts of rotary piston wet spray machine)

6, centralized lubrication system, effectively extending the life of wear parts.

7. The product wheel design is small and flexible, easy to move and easy to maintain.

8, the transport of small aggregate concrete, high-rise building mortar delivery.

9, heat insulation lightweight foam cement, mortar to warm, self-leveling ground construction.

10. Jetting of plain concrete and fiber concrete in various projects.

11, fire, insulation material injection (delivery).

12. The injection (transportation) of greening soil in the construction of ecological environment.

13. Pressure perfusion of various types of foundation piles, tunnel over-digging and backfilling, railway slope support, and disaster management.

KCPZ dust sprayer

Performance characteristics:

1. Having two inventions and utility model patents, the machine body and nozzles break the traditional limitations

2. The latest type of environmentally-friendly concrete injection equipment reduces dust by more than 90% compared with conventional jets, reducing environmental pollution and fully protecting the physical and mental health of construction workers.

3, the new nozzle device, mixing more evenly, rebound greatly reduced.

Innovation:

1, the upper and lower overflow and rotor friction plate leakage collection and export devices to prevent dust emissions.

2. The new dust removal technology and filter material have good filtering effect and long service life.

3, drawer type ash container, easy to clean.

4, multi-ring water sprinkler system to ensure uniform mixing.
