overview
During the production process in the pharmaceutical factory workshop, the sugar coating packaging in the sugar coating workshop emits talc dust, which affects the personal health and air quality of employees in the workshop. In severe cases, the accumulation of a large amount of dust may cause explosions and affect production. Therefore, the dusty air needs to be purified after collection before being allowed to be discharged into the atmosphere. Due to the small particle size of the collected talc dust, ranging from 0.5 to 1.0 μ m, and the presence of medicinal components, it needs to be recycled and reusedPharmaceutical workshop dust collectorFor 1.0 μ m dust, the dust removal efficiency is as high as 99%, the filtration effect is good, the external size is small, and the operation is stable, which is widely used in workshop dust removal by pharmaceutical factories.Pharmaceutical workshop dust collectorIt is also widely used in industries such as chemical, food, tobacco, metallurgy, machinery, building materials, laboratories, etc. for the purification of dusty gases and material recovery in processes such as material crushing, screening, grinding, belt conveying, silos, and packaging.
Structural characteristics of dust collector in pharmaceutical workshop
The main structure of the dust collector in the pharmaceutical workshop consists of an upper box, a middle box, a lower box (ash hopper), a cleaning system, and an ash discharge mechanism.
The dust removal efficiency of the dust collector in the pharmaceutical workshop is high, generally above 99%. The dust concentration in the outlet gas of the dust collector is within tens of mg/m3, and it has a high classification efficiency for fine dust with sub micron particle size. This device has a simple structure and is easy to maintain and operate. Not sensitive to the characteristics of dust and not affected by dust and resistance.
Working principle of dust collector in pharmaceutical workshop
Place the dust collector in the pharmaceutical workshop in an independent dust removal room, connect it with corresponding air ducts and vacuum hoods, plug in the power, turn on the fan button, and the dusty air enters the box through the vacuum hood, air duct, and air inlet from the dust source. Due to the sudden expansion of the airflow, the flow rate suddenly decreases, and large particles of fine powder do not separate from the dusty air under their own weight and settle into the ash drawer. The remaining dust particles are trapped on the outer wall of the filter bag due to the screening, collision, hooking, static electricity, etc. of the filter cartridge. The purified air is discharged through the outlet of the fan. The purified air of this unit can be directly discharged for indoor circulation without any loss of ventilation heat (cooling capacity). Automatic pulse cleaning is adopted, and there is no need to stop the machine during the cleaning process. Due to the use of pulse cleaning, users need to provide their own gas source.
Precautions for designing dust collectors in pharmaceutical workshops
1. Dust removal equipment ducts should be laid vertically or obliquely as much as possible, and when laid obliquely. The angle with the horizontal plane is greater than 45 degrees. When laying horizontally, a cleaning port should be set up to prevent dust from depositing in the air duct.
2. Choose the appropriate size of the wind speed inside the dust removal equipment duct. The wind speed inside the duct will affect the wear and tear of the equipment and air duct to varying degrees. If the wind speed is too low, it will cause dust deposition and block the pipeline. In order to prevent dust deposition and blockage in the pipeline, the air velocity inside the pipeline cannot be lower than the air velocity listed in the table below.
3. Due to the high wind speed, the dust removal equipment air duct usually adopts a circular air duct with a smaller diameter.
4. The exhaust points of the dust removal equipment should not be too many to facilitate the balance of resistance between each branch pipe. If there are too many exhaust points, a large section collection pipe can be used to connect each branch pipe.
5. Good hydraulic balance is required for the air ducts of dust removal equipment. For hydraulic calculations of parallel pipelines, general ventilation systems require a pressure loss difference of no more than 15% between the two branches, and dust removal equipment requires a pressure loss difference of no more than 10% between the two branches, in order to meet the design requirements for the air volume of each branch.
