Description
Technical Field

Background
The welding, cutting, shaping and cutting block of metal materials are basic processes for processing and maintaining metal products, and are widely applied. However, the smoke generated in the welding and cutting process not only pollutes the air, but also harms the health of people, so the smoke is listed in the main range of air pollution control of industrial production by the nation. At present, three general large, medium and small welding and cutting smoke dust purification devices are analyzed from the aspects of reducing smoke dust purification treatment cost, improving applicability and universality, and have the following common and individual defect problems: the energy consumption is big, the smoke and dust is administered with high costs, and application range is restricted, carries inconveniently, is the biggest resistance that promotes at present to weld and cut the smoke and dust and administer, specifically as follows:
(1) the different degree energy consumption that the smoking mouth of clarifier and the distance of welding and cutting the fuming point caused is extravagant: it is known that the larger the smoke diffusion range, the lower the smoke concentration, the larger the total amount of smoke-air required and the higher the energy consumption. The distance between the smoke suction port of the existing large smoke dust purification equipment and a welding and cutting smoke point is dozens of meters and dozens of meters far away, so the required smoke suction power is from dozens of kilowatts to dozens of kilowatts, even hundreds of kilowatts, and the energy consumption is large; in the existing medium-sized purification equipment used in a centralized area of welding and cutting points in a purification workshop, the height difference between a smoke suction port and the welding and cutting smoke points is generally about 3 meters, the power of the equipment is between several kilowatts and more than ten kilowatts, and the energy consumption is still very large; the existing small-sized purifying equipment used for a certain welding and cutting point position is limited by a smoke suction port, a smoke suction pipeline structure and a welding and cutting operation space, the height of the smoke suction port from the welding and cutting smoke point is generally set to be more than 1m, and the power of the small-sized purifying equipment still needs 1-2 kilowatts.
(2) The energy consumption that causes with clarification plant control desynchrony is extravagant in the welding: the existing welding and cutting equipment and the purifying equipment are respectively and independently controlled, for example, the large and medium-sized purifying equipment is almost started on duty and shut down off duty no matter whether welding and cutting exist in a purifying area, the number of welding and cutting points is large or small, and the concentration of smoke dust is high or low; although the small-sized purifying equipment can be started before the start of welding and cutting work, the welding and cutting are frequently stopped at different time intervals in the whole welding and cutting process due to welding and cutting auxiliary materials, replacement of welding pieces, movement of welding and cutting point positions, quality inspection and other processes, and the energy consumption waste caused by invalid idling of the purifying equipment in the welding and cutting time period is caused because the purifying equipment cannot be synchronously closed and started with the welding and cutting equipment in real time.
(3) And inconvenient carrying, and limited welding and cutting application environment: the existing small-sized smoke dust purification equipment still has larger size, larger smoke suction port, thicker suction pipeline, extremely limited suction pipe length and inconvenient movement, and can not meet the smoke dust treatment requirements of outdoor, underground, high-altitude, large-scale weldment, special posture and other welding and cutting environments.
(4) And harming human health: the nearest distance between a smoke suction port and a smoke generating point of the existing large and medium-sized smoke dust purification equipment is about 3 meters, workers are completely positioned below the smoke suction port, and are inevitably positioned in a smoke dust diffusion range, and the bodies of the workers are harmed by polluted air; although the small-sized purifying equipment smoke suction port is close to the welding point, the smoke diffusion range is relatively small, but workers still can be damaged to different degrees.
