How to effectively control dust pollution in concrete mixing

Submitted by Eliza,12/07/2015
With the development of society, now concrete mixing plant is accepted by more and more people. However, due to the weak consciousness of people, the pollution of concrete mixing plant is more and more serious. The pollution of concrete mixing plant is mainly in three aspects. First is the pollution of dust, the second is the noise pollution, and the third is the pollution of sewage. Dust control will be the main direction of the development of concrete mixing plant in the future. So, the dust pollution control of concrete mixing plant lies in the way of conveying the material.
1. Establish a closed material yard
Because the technical level of Chinese building materials industry is backward, the gravel has not been washed, the dust content is high, the process of storage and transportation is more prone to dust, the dust content is higher in the sand. In the city commercial concrete mixing plant, the closed aggregate field is introduced into the aggregate storage yard. The new building material hollow brick is used, which can not only make the dust not emit in the surrounding environment, but also can reduce the noise pollution.
2. The concrete mixing plant adopts totally enclosed outer package
Host adopts sealed package, and aggregate material belt machine also use color steel tile to package, which can reduce the probability that the dust discharged into the atmosphere when transport the aggregate.
3. Effectively remove the dust of the host
The negative pressure dust collector we studied (including the desiccant function) can ease the instantaneous pressure and filter the water.
4. Remove the dust of the cement silo
The traditional way of removing dust is to install the bag type dust collector on the top of the warehouse, but the effect is general, based on the bag type dust collector to increase the pipe type dust collector, it can filter the atmospheric further.
5. Adopt the way of water spraying of the main engine
Increasing pressure pump, improving the nozzle structure, forming a water curtain, to suppress dust generated when feeding on the host.
