Fine polishing the dust suction trap rate

Grinding polishing dust suction trap rate machine grinding polishing dust suction trap rate is also called control wind speed, refers to overcome the pollution of dust gas diffusion force plus appropriate safety coefficient of wind speed. Only when the gas-collecting hood at the pollution caused by the wind speed is greater than the control when the wind speed, to reduce pollution gas suction people come in to the enclosure. Control the wind speed is not only related to process equipment category and pollutant distribution condition, also with the harm of pollutants, and the airflow around the disturbance factors. To select a correct and appropriate control wind speed is an important link in calculating exhaust exhaust air. Control the speed of the gas-collecting hood control effect and important index of system economy, control the speed selected too small, the pollutant can't completely drawn into enclosure, and the surrounding environment. Selection is too large, then the inevitable exhaust, and make the system load and to increase equipment. Fine polishing the precipitation station side suction hood grinding polishing machine when pollutants cannot be sealed, the upper cannot set when the gas-collecting hood, can set a side sucking hoods, but the effect of the side suction hood than upper umbrella gas-collecting hood is poor, at the same time the requirements of the exhaust air volume is bigger also. Process for cold, side suction hood is also on the principle of suction effect, therefore when installation should be close to the sources of pollution, as far as possible or displacement will increase greatly. Side suction in the form of many, when choosing mainly not impede operations for the principle. Different forms of side sucking hoods, the calculation of exhaust air is different.
