Embodiment 1

[0018] Take the application of the present invention in welding construction in natural gas pipeline cross-river tunnels as an example.

[0019] Such as figure 1 and figure 2 As shown, the present invention is a safety control device for welders in a special working environment, including a smoke and dust discharge treatment device and a purification air supply device. In the opposite direction of the exhaust port of the device, the two sets of devices are activated at the same time during use; the on-site soot discharge treatment device includes a side suction hood A for smoke and dust, and a first-stage filter is arranged inside the side suction hood A for smoke and dust. The dust side suction hood A is connected to the first and second stage filter C through the communication pipe B, and the first and second stage filter C is connected with the first electronic purifier D, namely the first and third stage filter, so The above-mentioned first electronic purifier D is conn...

Abstract

The invention relates to a safety control device for welders in special operating environments, which comprises a soot local discharge treatment device and a purification air feeding device. The purification air feeding device is arranged opposite to the direction of an exhaust port of the soot local discharge treatment device, the two devices are started simultaneously when the safety control device is used, the soot local discharge treatment device consists of a side draft hood, a primary filter, a secondary filter, an electronic purifier, an activated carbon absorber, a fan section, a control cabinet, a discharge pipe and the like, and the purification air feeding device comprises a sucking opening, a primary filter, a secondary filter, an electronic purifier, a fan section, a control cabinet, a hose and an air feeding hood. By the aid of the safety control device, soot and harmful gases, which are generated due to welding operation on the ground, in underground narrow spaces or tunnels can be effectively exhausted, treated soot meets the emission standard for occupational environments, non-toxic, dust-free, clean and hygienic air is supplied to a breathing zone of the welders, and the operating environments meeting health requirements are assuredly provided for the welders.

Description

technical field [0001] The invention belongs to the technical field of special operation environment safety control, and in particular relates to a human body health and safety protection device for welders in a special operation environment. Background technique [0002] Welders will produce a large amount of harmful fumes during welding operations. If they are not eliminated in time or treated harmlessly, the concentration of harmful substances in the air in the breathing area of ​​the welder's body will increase rapidly. If a person inhales harmful gases with a concentration exceeding the standard, then As the working time increases, the health hazards to welders will increase. This hazard has become a consensus in industrial production. The special working environment refers to the welding work space in the narrow space or tunnel on the ground or underground, where the air is not easy to circulate or it is difficult to use mechanical exhaust to discharge harmful fumes. ...
