Technical Field
The utility model relates to a weld cigarette dust collector, especially relate to a high-efficient smoke and dust purification filter equipment of pump drainage under high negative pressure follow-up belongs to welding smoke and dust filtration dust removal technical field.
Background
Welding is a basic process for connecting materials with each other industrially, is widely applied to the fields of civil engineering, machinery and material processing, and has wide application prospect along with the continuous promotion of the industrialization degree of China.
However, the application and development of welding technology are restricted by harmful factors generated in the welding operation process. Harmful factors in the welding process can be divided into electric welding smoke dust, toxic gas, high-frequency electromagnetic field, rays, electric arc radiation, noise and the like. Wherein, the welding fume is fine particles formed by the welding material under the action of high temperature along with the welding process. It is statistically estimated that about 0.5% of the metallic welding materials consumed worldwide every year are converted into welding fumes.
Welding fumes in the broad sense are a complex mixture, divided into a solid phase part and a gas phase part, the solid phase part of which contains Fe2O3、MnO2Metal particles such as Sn and Pb, and the gas phase part contains gases such as NOx, CO and HF; welding fume in the narrow sense refers to fine solid particles formed during welding, and generally, welding fume is collected and purified, which refers to welding fume in the narrow sense. In a limited space or a closed space, welding smoke dust with small particle size is suspended in the air, and can not be automatically settled or eliminated because a large amount of welding smoke dust is gathered in the operation space, so that great harm is caused to the health of welding operators and the construction environment. It has been found that particles having a particle size of less than 10 μm can enter the trachea and bronchi, and particles having a particle size of less than 2 μm can enter the interior of the respiratory system and are not easily discharged from the body. Most welding smoke dust can enter the respiratory system of a human body, the deposition rate of the welding smoke dust in the lung is over 50 percent, and the excessive deposition of the welding smoke dust in the lung can cause the pathological changes of the respiratory system, such as pneumoconiosis, manganese poisoning, metal fever, emphysema, chronic bronchitis, even lung cancer and other diseases. According to investigation, the proportion of respiratory diseases suffered by people who are engaged in welding work is much higher than that of workers in other industries, and the risk of suffering from lung cancer is about 30% higher than that of other people.
Besides causing damage to the physical health of workers who directly engage in welding, the welding smoke dust and the dust can also move along with the airflow in a limited space, and threaten other workers who work in the whole factory; and the smoke dust is gathered at the part where the air flow is slow, the air quality in the operation space is deteriorated, the visibility is reduced, and hidden troubles are brought to the construction and production safety.
At present, a ventilation method is mainly adopted for welding fume dust removal, welding fume particles move along with air flow in space, and fume is taken away from a working area through reasonable air flow organization, so that the indoor fume concentration is reduced, and the air quality is improved. The ventilation purification can be divided into two categories of natural ventilation purification and mechanical ventilation purification, the welding construction site has a complex structure and a large space volume, and the requirement is difficult to meet by only depending on the natural ventilation purification, so that the mechanical ventilation purification mode is mainly adopted in the factory building of the enterprise. Although there are many mechanical ventilation devices on the market, all have several disadvantages, such as unsatisfactory dust removal effect, substandard purification, huge equipment occupying space, incapability of removing dust at fixed points, incapability of removing dust with follow-up, and the like.
