Fly ash is a fine powder that is a by-product of burning pulverised coal in power plants. This residue, known as fly ash, is produced when the mineral impurities in the coal fuse together as it exits the combustion chamber and then cools and hardens. When mixed with lime and water, fly ash forms a compound similar to silicate cement. As we all know, fly ash plays an important role in the cement industry, pharmaceutical field, building materials field, agricultural production, etc. due to its wide distribution of raw materials, simple production process and low cost. In the cement industry, the use of fly ash batching can reduce the raw material cost to the cement enterprises and enhance the competitiveness of the enterprises, and the effective storage of fly ash is the first thing to consider. If the fly ash is collected and stacked in the open air, it not only occupies a large amount of land, but also pollutes the air and groundwater at the stacking place, causing great harm to the environment, and it is not suitable to be adopted for open storage. Therefore, how to safely and properly store fly ash has become a concern for many people.
Different ways of storing fly ash
1、Bulk storage: When storing fly ash in bulk, be sure to pay attention to moisture-proof and waterproof. Fly ash should be agglomerated after moisture, which reduces the strength and even can't be used. Therefore, for bulk storage of fly ash, it is necessary to add cover to prevent rain when storing. In addition to the storage of fly ash warehouse, should also be kept dry, the roof and external walls shall not leak; temporary open storage of fly ash should be taken to prevent rain, and with linoleum, tarpaulin or oil paper and other padding to prevent moisture. This kind of storage will cause certain environmental pollution and occupy a large area.
2、Bagged storage: bagged fly ash will be similarly agglomerated after moisture, reducing the strength, and even can not be used. Therefore, for bagged fly ash, do not break the paper bag. Warehouse for storing bagged fly ash should be kept dry, and the roof and external walls should not leak; the ground mat is not less than 300mm from the ground, and the surrounding area of the fly ash stack is not less than 300mm from the wall, and the stacking height should not be more than 10 bags in general; this kind of storage requires a lot of manpower and material resources, and it is strict on the requirements of the storage environment, and it requires a lot of time and space to maintain a dry environment.
3, steel plate warehouse storage: steel plate warehouse as energy saving, sealed, environmentally friendly equipment, in the fly ash building materials industry has been widely used. Fly ash is stored in large
Steel Plate Silo in sealed, to ensure the quality of fly ash and improve the utilisation rate. The steel plate silo occupies less area than the traditional open storage, which can save land resources. Environmental standards to prevent environmental pollution, can effectively solve the problem of dust pollution of the air, grey water pollution of water bodies.
Steel plate warehouse storage of fly ash related considerations
Nowadays, the emergence of steel plate warehouse solves the problem of fly ash, so that it is no longer open storage, no longer occupy a large area of land resources, to protect the environment and protect people's health. But storing fly ash with steel plate is not foolproof, dust explosion may occur. Therefore, today Dazheng steel plate warehouse manufacturers will introduce some of the relevant considerations about the storage of fly ash in steel plate warehouse!
First, to strengthen management, improve safety awareness, enhance everyone's sense of responsibility, the steel plate warehouse storage of fly ash for a knowledge campaign.
Second, do a good job of safety monitoring, daily check by check, timely solution to some safety hazards, to avoid dust explosion.
Third, the steel plate warehouse must be designed and installed with better dust and explosion-proof technology, which can greatly reduce the probability of dust explosion. Dazheng's engineers in the design of fly ash steel plate warehouse at the beginning of the consideration of the possibility of explosion in the process of transport and storage of fly ash, so the steel plate warehouse storage system to add dust removal system, ventilation system, explosion-proof system.
Fourth, keep the steel plate silo ventilated when feeding, reduce the concentration of dust, so as to avoid too high a concentration of dust explosion! Large being steel plate silo ash conveyor pipe on the interface to set the cut-off valve to ensure that the use of the ash conveyor system is not affected, to avoid back to the material.
How to choose to qualified steel plate warehouse manufacturers?
1.Look at the construction qualification of the steel plate silo manufacturer, we have to check whether the construction company has the corresponding construction qualification, induction certificate, title certificate and so on.
2. Look at the construction cases of
Steel Silo manufacturers. Steel silo companies will have their own official website. We can look at the official website to see the engineering performance of the steel silo manufacturers. The more construction experience and cases, the more reliable.
3.Look at the accidents of the steel warehouse manufacturers to see whether the constructed steel warehouse has had any major safety accidents.
4. Look at the verification certification system to see if the company has quality management system certification, environmental management system certification, occupational health and safety management system certification and so on.
