Malani After-sales Micro Classroom | How to Prevent and Control Dust Caused by High Temperature in Summer?

In the north of the country and some dry areas in the northwest.，On a hot day，The plant area of the asphalt mixing station has been exposed to the sun for several days.，Dry air is particularly prone to the wanton diffusion of dust.。Dust is an important pollutant in Asphalt Mixing Plant.，Therefore, the prevention and management of dust in these areas is essential.。

Plant management

A Standard Asphalt Mixing Plant Production Base，Good plant management is indispensable.。Good plant management can reduce dust emission，Improve the comfort of the plant area。                                           
In dry weather，Dust ducts in the plant area shall be watered regularly.，Minimize fugitive dust emissions from loader and Truck access，Clean up the scattered objects or debris in time.。

Cold silo dedusting system

The dust of asphalt mixing equipment is mainly produced in the process of feeding and heating in the cold silo.，The cold aggregate feeding belt is equipped with a separate dust removal system.，Induced draft fan during production、The pulse precipitator enters the working mode.。

（Cold silo）
When loading the loader，The dedusting detector detects that the loader is in place.，Automatic opening of air door valve of corresponding stock bin，The bunker dedusting device collects the dust generated by the unloading of the loader.。

After the loader leaves, the air gate valve of the corresponding silo is closed in a delayed manner.。At the same time，The dedusting and sealing device collects the dust generated at the feeder belt and the adapter.。

Dust removal system of mixing main building

Screening in the main building、Measurement、Stir、Hot material bin and other dust-raising parts are equipped with negative pressure dust removal device.。The dedusting system adopts atmospheric blowback dedusting.，Two-stage dedusting、Off-line dust removal，Ffectively prevents the dust from overflowing。

Enclosed mixing main building

In order to control the disorderly emission of dust in the main building from the root.，The main building of the mixing plant is fully enclosed.，Negative pressure treatment is adopted inside，Avoid dust accumulation inside the main building。
Specially designed overflow temporary storage bin，Overflow can be achieved、Over-limit material stockpiling processing，Centralized processing when the warehouse is full，Effectively prevent dust caused by continuous spillage。

（The main building is closed，Lane closed）                              （Discharge lane dust collector）

Cold materials shall be stored in a closed manner

The cold aggregate bin shall be stored in a closed plant or silo.。Fully enclosed design of material yard，Prevent the dust from drifting outside，But also can avoid that increase of the moisture content of the aggregate due to rain when the aggregate is stac in the open air.，Reduces additional energy consumption for aggregate drying。

（Cold silo cover）

Maleny for different types of brands of Asphalt Mixing Plant，Provide a full range of environmental upgrading services。According to the specific needs of customers， Reasonably designed reconstruction scheme，The pollutant discharge of the existing asphalt mixing plant in the production process is reduced to the range of the local environmental protection standard.。
