How to remove dust
Thread Content
Our company uses anthracite lump coal to produce water gas. A large amount of dust will be generated during the transportation of lump coal. How can we prevent and remove dust to meet environmental protection and occupational health requirements? The general coal transportation process is: The lump coal is transferred to the 1# belt, vibrating screen, 2# belt, 3# belt through the feeder, and then enters the silo of each gas generator. The places where dust is likely to be generated are the vibrating screen and the 3# belt. These two places are the focus of treatment.
My company also has the same problem and hopes to find ways to control and deal with dust. Thanks.
Dust off. Optional pulse bag dust collector, two parts share one set of devices.
Dust removal is a comprehensive management project, which mainly focuses on two aspects, one is dust suppression, and the other is dust removal. For existing installations, dust suppression methods are limited, and it is difficult to think about dust suppression from the equipment (equipment modification). We mainly think of ways to suppress dust from the aspects of environmental sanitation management (setting up ground water flushing, etc., strengthening production management, etc.) and controlling the humidity of coal. ； For dust removal, negative pressure ventilation dust removal is mainly used, and small electric dust removal devices or water dust removal equipment are installed at the blanking point. The dust removal equipment of the coal conveying device now has higher requirements for equipment management, a higher failure rate, and if the management cannot keep up, the dust removal equipment will be abandoned. According to your description of the situation, it may be caused by the inexperience of the design team and poor consideration of dust removal. It will take a lot of effort to deal with it. It’s difficult to discuss in detail. If you have other questions, you can send me a text message and we can communicate with each other. Also ask the heroes: Which are the main equipment manufacturers of the longer corrugated side belt conveyors used by Shell, and what are the main problems in the production process?
Just use the pulse bag dust collector for coal mills produced by Hefei Fengde. Because the coal dust is relatively fine, the following safety measures need to be taken: 1. The dust collector has an explosion-proof opening 2. The dust bag is waterproof, oil-proof and anti-static 3. The ash hopper cannot accumulate dust for a long time to avoid spontaneous combustion 4. The temperature of the ash hopper must be measured 5. It is best to install a carbon dioxide automatic fire extinguishing system
In the south, for bag dust collectors, the humidity of coal is relatively high, and coal powder is easy to stick to the bag. Reliable drying and other anti-coal bag sticking technologies are needed. In addition, the reliability of the dust collector needs to be paid attention to. If the reliability is not high and management and maintenance are not in place, these dust removal facilities will become decorations. This is the case in many domestic coal conveying systems.

This friend is right. When the temperature is low, the moisture is high, and the water is saturated and precipitates into condensation lakes. It is troublesome to clean it manually. When the fineness of coal changes to a certain extent, from quantity to quality, the stability of the coal changes. The main problem is to be explosion-proof and safe.
Has anyone considered using microwaves to remove dust? Other methods are not very suitable.
Microwave dust removal is a new technology. Please introduce its characteristics. Is there any engineering application performance? What is the application situation?
Install dust cover and pulse bag dust collector to increase the humidity of coal appropriately!
