Drying equipment is mainly used to dry powder or granular materials. It is widely used in food, pharmaceutical and other industries, but there are also some problems. For example, during the drying process, dust diffusion is an unavoidable problem in the current drying process. There are many types of dust, some of which can cause serious harm to human health, and can also cause pollution in the work area and even affect the production process and products. As the national regulatory policy becomes more stringent, the dust problem caused by drying equipment needs to be taken seriously. So is there a way to put an end to this phenomenon, how can we effectively reduce the spread of dust?
The technical staff of Jiangyin Lingling Machinery Manufacturing Co., Ltd. explained several ways to reduce the dust diffusion of the rotary dryer during work:
Seal control. It can be partially sealed, integrally sealed or sealed, and the dust-producing point can be sealed with a sealing cover, which can greatly reduce material scattering and dust.
Eliminate the height potential difference of the dryer. The difference in the height potential of the dryer is the main cause of the dust spill. The elimination of the height potential difference is caused by the hopper, the protective cover, the chute, etc. of the handling equipment due to the drop of the powder. The drop should be minimized to reduce the inclination of the chute chute, and it is better to have a negative pressure in the closed chamber, which is beneficial to the collection of dust.
Use transportation equipment with good sealing performance. Reduce the height difference and inclination of the discharge stream and set up a flow-through facility as much as possible. It not only enhances the flexibility and efficiency of the configuration between the various operations, but also reduces the scattering and dust.
Use the exhaust system. In order to prevent the dust from giving us more pollution, we can also remove the indoor dust through the exhaust system, that is, remove the indoor exhaust gas.
In addition, with the emphasis on the dust problem in the production of food and medicine, dust removal equipment for dedusting has also appeared on the market. It is understood that in the dust removal process, the industry commonly uses such as bag dust removal, electric dust removal, and wet dust removal. The insiders reminded that in the process of use, because the dryer does not have different materials and different properties, the requirements for dry products are also different. When using, the suitable drying should be selected according to the nature of the drug and the requirements of the product. Methods and equipment. Among them, the bag dust removal is mainly for the dust removal of 0.1 micron particles, and the dust removal efficiency can reach more than 90 , so it is also favored by the market.
It is understood that the pulse bag filter adopts the compartmental air-discharge pulse blowing cleaning technology, which overcomes the shortcomings of the conventional pulse dust collector and the compartment back-blowing dust collector, has strong cleaning ability, high dust removal efficiency, low emission concentration and low air leakage rate. The energy consumption is small, the steel consumption is small, the floor space is small, the operation is stable and reliable, and the economic benefit is good. It is suitable for the purification of dusty gas and the recovery of dust materials in food, pharmaceutical, machinery, chemical and other industries. At present, the competition in the pulse bag filter industry is increasingly fierce, and more and more manufacturers are seized the opportunity to promote and upgrade the equipment. For example, Changzhou Fengneng Dry Engineering Technology Co., Ltd. is an ideal product for environmental dust removal based on individual design and continuous innovation. It is widely used in ventilation, dust and dust in chemical, pharmaceutical, feed, building materials and grain processing industries. Recycling.
With the rapid development of the food and pharmaceutical industries, the production process and the environment are more stringent, and the dust problem needs to be solved urgently. The industry expects that the future dust removal equipment will also usher in new development opportunities, dust removal equipment manufacturers should seize the opportunity to accelerate equipment upgrade and transformation.
