What is ventilation and dust removal? Ventilation dust removal is a way to control the source of dust. It is currently a widely used dust -proof technical measure. Ventilation dust removal is usually set up vacuum cover at the source of the dust or its nearby. The fan uses the fan as a power to inhale the dust generated during the production process and the gas loaded with the dust of the dust. Then discharge the atmosphere through the duct. In this way, it can prevent the dust from entering the room, the air in the pollution workshop, but also to prevent it from being distributed outdoors, polluting plant areas and atmospheric environments.

The system of ventilation dust removal system consisting of a vacuum cover, dust collector, duct and fan is called a ventilation dust removal system, as shown in the figure below. However, because the dust source is different from the selected dust removal equipment, not each system must include these devices. For example, smoke gas can be pulled directly from the industrial kiln, and there can be no vacuum cover; when the dust removal unit is set on the spot, the gas can be directly discharged into the room after purification, and you can do not blasting. And when using the residual pressure and exhaust of the process equipment, there can be no fan. However, when the dust concentration of the excreted gas exceeds the emission standard, there should be a dust collector. The characteristics of ventilation dust removal system . The division principle of the ventilation and dust removal system The division of ventilation dust removal systems shall be determined according to specific conditions such as production equipment and configuration, process process and other principles: 1. In the same production process, the equipment and dust production points that produce the same dust can be produced at the same time, which can be combined into a ventilation dust removal system. 2. For equipment and dust production points that produce different types of dust at the same time, it is generally not suitable for a system. If the production process allows different types of dust to be mixed recycling, it can be combined into a system, but when there is a system with the following situations: (1) When mixed ; (2) Dust -containing gas with different temperatures and humidity may be exposed in the air duct; (3) When the dust is different, the dust removal dust removal efficiency is large. . The form of ventilation and dust removal system The form of ventilation dust removal system should be determined according to the conditions of process equipment, production processes and factory structures. It can usually be divided into the following three types: 1. Local style. The local ventilation dust removal system is to directly set the dust collector or the dust removal unit on the dust -producing equipment to capture and recycle dust on the spot. This system has a compact layout, simple structure, and convenient maintenance management. It can also achieve the purpose of preventing dust from outside and purifying dust. However, due to production and process conditions*, this system is currently only applied to some dust -producing equipment, such as sand mixed machines, belt machine transfer points, and warehouses. 2. Differential. The decentralized ventilation dust removal system is to do one or several dust production points -a system, the dust collector and fan are installed near the dust -producing equipment. Generally, the production*operator will be treated, and there is no special person management. This system has the advantages of short pipelines, simple layout, easy resistance to balance, and convenient air volume adjustment, but it is more troublesome to deal with after dust. It is suitable for occasions where dust production equipment is relatively decentralized and the factory has the location of the dust removal equipment, such as sintering plants, casting plants (workshops), and so on. The mechanical processing workshop mostly uses single -machine dust removal, that is, each machine tool is equipped with a dust removal unit, and the dust -containing gas is directly discharged into the workshop after purification. 3. centralized. The centralized ventilation and dust removal system is to concentrate the dust production points of multiple dust production points or the entire workshop and even the entire factory into a system. There are special dust removal rooms, which are managed by a special person. This system has a large air volume, which is convenient for centralized management. It is easier to process after dust, but the head of the pipeline is complicated, the resistance is not easy to balance, and the air volume adjustment is difficult. It is suitable for the concentrated dust production equipment and conditions for setting up the dust removal room, such as refractory material factories. For multi -storey plants with multiple dust -producing points, all the top floors can be used as the dust removal room, and the dust production points of each floor can be connected to the top dust collector to purify the back row.
A complete ventilation and dust removal system should include the following processes:
1. Use the exhaust hood, including the dust cover to collect the dust -containing gas;
2. Dust gas -containing gas through ventilation pipelines;
3. Separate dust in the dust removal equipment;
4. Excess the purified gas through the chimney to the atmosphere; n n n n n n n n n n n n n n n n n n n n n n n r n5. Dust the dust separated in the dust removal equipment.
therefore, the main equipment in the ventilation dust removal system is: exhaust hoods, fans, pipes, dust collectors, chimneys, ash -mouting devices, etc. However, in various specific circumstances, not each system has the above devices, such as direct smoke from the furnace, and there is no exhaust hood; when the dust source is set up nearby In the room, you can do not pipes and chimneys; when using hot pressure to discharge hot flue gas, there can be no fan and so on. However, there should be dust removal equipment under normal circumstances, but different dust removal equipment selected according to different process equipment and requirements. The exhaust hoods, dust collectors, and fan of the ventilation dust removal system are linked between the main equipment such as ventilation pipes. The design of the ventilation pipe network is to determine the location of each equipment and the size and layout of the ventilation pipeline.
The layout of dust removal equipment is related to process equipment and workshop layout. Generally, the dust collector and the process equipment are as close as possible. This is not only compact to the equipment layout, but also can shorten the length and energy conservation of the pipeline. However, in some cases, especially when the air volume is very large, the dust collector and fan should be set up in it. Stay away from the source of the dust and set it outdoors. In this case, it is very necessary to carefully arrange and calculate the pipeline, otherwise it will bring a lot of adverseness to the future operation and maintenance. If the design of a complete ventilation and dust removal system is unreasonable, it may not only waste materials and materials and materials and materials. Energy, it may cause dust to deposit in the pipeline, cause the pipeline to block, and clean up the blocked pipeline is very troublesome.
