China's environmental products shocked the Beijing-Tianjin-Hebei sanitation exhibition

Recently, the “2017 Beijing-Tianjin-Hebei 3rd Urban-rural Environmental Sanitation New Technology and New Equipment New Process Exposition” was opened in Hebei Zhangzhou International Convention and Exhibition Center. The exhibition was attended by hundreds of industrial enterprises headed by Zoomlion Environment. The top-level municipal solid waste solid waste disposal, urban and rural sanitation facilities and equipment, cleaning equipment, and other thousands of environmental sanitation products throughout the chain. The environment of the China United Environment Protection Equipment Co., Ltd. carrying dust, high-concentration sewage treatment equipment, kitchen garbage collection vehicles and other high-tech environmental protection equipment is even more amazing, and has become the focus of the entire exhibition.

The haze strikes the dust

It is reported that the main sources of urban dust are construction site mines and municipal roads.

Today's construction site mines usually have only simple stacking materials to cover and spray dust, vehicles for artificial mud removal and washing, and the overall dust reduction effect is poor. Especially in the northern regions, the climatic conditions are dry and the air humidity is low. This can easily cause serious construction dust, soil dust, and dust at the yard. This not only jeopardizes the health of the construction workers, but also affects the air quality of the city. In case of strong winds and other harsh climates. It will also cause dust, sandstorms and even dust storms.

In the process of dust control on municipal roads, at present, most cities in China still adopt the method of spraying water and dust, and do not effectively control road dust and secondary dust generated by rolling, blowing, and cleaning, causing road dust. Multiple settlements and repeated pollution.

Zhonglian Artifact Debut

To curb the dust on the construction site, the domestic construction system regulations throughout the country stipulate that “six 100%” will be resolutely implemented for the construction site construction, that is, 100% enclosure around the construction site, 100% coverage of materials, 100% flushing of vehicles entering and exiting, and 100% construction site ground Hardened, demolition site 100% wet operation, muck vehicles 100% confined transportation, crackdown on air pollution prevention and combat.

In the face of the government’s urgent need to solve the problem of air pollution prevention, Zoomlion Environmental Research has developed a series of supporting dust control equipment and formulated a “two-in-one” dust dust treatment solution.

"Two-in-one" dust control integrated solution

A major source of dust at the construction site is dust from piled materials. According to repeated experiments conducted by industry insiders, the traditional felt-cover dust-removing, water-jet dust-removing capacity, and spray dust suppression agent are the best, and there is no secondary pollution.

Zhonglian Environment ZLJ5250TDYD multi-function dust suppression car

The spray dust suppression agent needs to be equipped with professional spray dust suppression equipment. The ZLJ5250TDYD multi-functional dust suppression vehicle exhibited at this exhibition has dust cloud suppression technology to further enhance the dust suppression effect.

In the environment of the multi-functional dust suppression vehicle through the high-pressure air gun atomized water into a "cloudy" water droplets. At the construction site, agglomeration type dust suppression agents are selected. Using the characteristics of “clouds and fog” particles, the contact area between the dust suppression agent and the dust is fully increased, so that the dust collides and agglomerates to form agglomerates, and the agglomerates become larger and heavier until natural. Settlement, rapid settlement, to achieve the purpose of eliminating dust. In factories and mines, adhesive dust suppression agents are used, and the consolidation, covering, silicification and polymerization principles are used to form a consolidated layer with a certain strength and hardness on the surface of the material to resist the destruction of wind and other external factors to achieve dust suppression.

Another major source of dust on construction sites is the transport of waste. In traditional cargo transfer vehicles, there is no seal structure or poor sealing of the tank. In the process of trans-shipment, the slag soil is likely to leak and cause secondary dust during transportation. However, the ordinary garbage collection and transportation vehicles have small loads and are not suitable for use. Landfill transportation.

Dump-type garbage truck

The environment-friendly and intelligent dump trucks developed by Zoomlion Environmental Technology have a U-shaped cargo box and a sealed design. They are stamped and formed by high-strength wear-resistant steel plates. They have low weight, low center of gravity, and no hanging material. , shock resistance, high durability features. The box has no exposed ribs, no sludge is accumulated in the loading, and it is easy to wash out. It also avoids dust pollution during transportation.

In addition, the dust pollution of municipal roads mainly comes from the dust entrained in the waste transportation vehicles, and the secondary dust caused by the accumulation of dust in road construction projects. At present, most cities adopt sprinkler vehicles to spray dust. They have not targeted road dust and secondary dust generated by rolling, wind blowing, and sweeping, resulting in multiple settling and repeated pollution of road dust.

Washing vehicle

In 2007, Zhonglian Environment combined with the characteristics of the domestic market, took the lead in the domestic development of a multi-purpose cleaning vehicle that has obtained a number of national patents. The multi-functional cleaning vehicle has various functions such as road cleaning, road surface cleaning, brushing on the edge of the road and along the stone facade, and low pressure flushing. It is especially suitable for high-cleaning sweeping and dust removal operations on road surfaces and roadsides, as well as general cleaning operations such as cleaning and cleaning of road surfaces and roadsides. And it has a cleaning and recovery mechanism for sewage, to a great extent avoid secondary pollution caused by sewage flowing. According to statistics, the cleanliness and decontamination rate of road surface under the high cleanliness operation mode can reach 97%.

With the development of urbanization, the road width of urban roads has gradually widened, and eight-lane and ten-lane roads in cities have gradually become mainstream trends. Especially in newly-built development zones, due to the large number of construction vehicles, the demand for road cleaning and dust reduction is increasingly urgent. Traditional sprinklers have low flushing pressure and do not remove the road surface to trap dust.

ZLJ5250GQX high pressure cleaning vehicle

In this case, the ZLJ5250GQX high-pressure cleaning truck can be equipped with a hydraulic high-pressure jet rack to clean the old stains and sticky dirt on the road surface. The high-pressure angle spray can be used to clean the curbs, guard rail fences, etc. The pre-shoot duckbill, back hedging, and post-sprinkler devices can be used for flushing and watering operations on highways and other places, respectively. After several generations of high-pressure cleaning vehicle equipment technology, the entire vehicle waterway is optimal, and the cleaning efficiency reaches over 95%.

City sidewalks, non-motor vehicle lanes, etc., as the "last mile" for dust treatment of municipal roads, are difficult to load on large roads due to the fact that the road surface material cannot be loaded and have a narrow width. Pure labor and cleaning are inefficient, and it is difficult to meet the city planning requirements. At this time, small pavement maintenance equipment is needed.

ZLJ5020TYH Road Maintenance Vehicle

ZLJ5020TYH road maintenance truck is equipped with front sprayer fixed-point cleaning device, left and right independent angle spray automatic cleaning device and high-pressure hand-held spray gun. It is particularly suitable for cleaning city sidewalks, non-motor vehicle lanes, stalls oily ground, curb, road yellow, white marking lines, cities Psoriasis.

exhibition site

China United Environmental Roads and construction dust control products shocked the Beijing-Tianjin-Hebei environmental sanitation exhibition and helped fight air pollution in the Beijing-Tianjin-Hebei region. Its excellent performance and performance at the exhibition attracted many guests to watch. (This article comes from Zoomlion Environment)
