Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the embodiments and with reference to the accompanying drawings.

[0017] A welding waste gas treatment device, the device comprises an inlet pipe 3, an outlet pipe 6, and an exhaust gas treatment chamber 5, a primary filter chamber 10, and an exhaust gas adsorption chamber 11 sequentially connected between the inlet pipe 3 and the outlet pipe 6; wherein,

[0018] The exhaust gas treatment chamber 5 and the primary filter chamber 10 are divided into upper and lower layers by the filter partitions 4, 4' with many small holes around them, and the waste gas adsorption chamber 11 is separated by the filter partitions 4" with many small holes around them. The filter cotton 9 arranged in the space above the filter partition 4" is divided into upper, middle and lower layers. The filter cotton 9 is provided with an exhaust gas adsorber 8 composed of molecular sieves, activated carbon and oxidants...

Abstract

The invention discloses a welding waste gas treatment device which comprises an air inlet pipe, an air outlet pipe, and a waste gas treatment chamber, a primary filtering chamber and a waste gas absorbing chamber that are sequentially connected between the air inlet pipe and the air outlet pipe. On the premise that secondary pollution is guaranteed not to be caused, workshop operation is not affected, and the service life of equipment is not influenced, the welding waste gas treatment device adopts a multi-stage purifying device for the purification treatment of welding waste gas, thus not only effectively removing the welding smoke waste gas, but also degrading the tar smell of the welding smoke and various toxic and harmful gases. By the method combining physics and chemistry to treat the welding smoke waste gas or industrial waste gas, the device can fully treat the welding smoke waste gas or industrial waste gas, is high in efficiency, and has the advantages of being simple, economical and practical in the actual use and operation.

Description

technical field [0001] The invention relates to a waste gas discharge treatment device in a welding process, in particular to a welding waste gas treatment device in a welding process. Background technique [0002] In addition to a large amount of smoke and dust, the welding operation also contains a large amount of various harmful gases and gasified or atomized chemical substances. Its main components are CO (carbon monoxide), HC (hydrocarbons), PM (particles, soot) and other harmful gases; if nitrogen is flushed, NOx (nitrogen oxides) will also be produced. If not treated, it will fly in the air, and it can invade the human liver, lungs, cardiovascular and blood through the respiratory tract. These toxic substances are seriously devouring human health. lead to the emergence of many occupational diseases. Such as: lung cancer, asthma, eczema, bronchitis, skin allergies, respiratory tract infection, etc. In severe cases, the central nervous system will be disturbed, the d...
