Problems solved by technology

[0002] At present, semiconductor device companies often use automatic welding equipment. The main component of the flux used in welding equipment is rosin. Rosin will generate a large amount of waste gas after heating. If the waste gas is not collected and treated in a centralized manner, it will not only pollute the atmosphere, but also affect people. health
However, most of the current rosin factories simply collect the waste gas and discharge it directly into the atmosphere without any treatment, thus causing serious air pollution. How to overcome the above technical problems has become the direction of efforts of those skilled in the art

Abstract

The invention discloses a welding waste gas treatment unit for semiconductor device manufacturing. The welding waste gas treatment unit for semiconductor device manufacturing comprises an ionization bucket, an ionization rod, a main precipitating bottle and a sucking pump, wherein the side wall of the ionization bucket is provided with at least one inlet pipe; a thermodetector and a manual valve are arranged on the inlet pipe, and are both connected with the flow meter of a micro differential pressure sensor; the manual valve is located between 2 flow meters; the ionization rod is embedded into the cavity of the ionization bucket, and the ionization rod is provided with a plurality of ionization needles on the external wall; the main precipitating bottle is arranged on bottom of the ionization bucket; one end of the exhaust pipe is connected to the upper part of the ionization bucket, and another end of the exhaust pipe is connected to an auxiliary precipitating bottle; a escape pipe is connected to the exhaust pipe near the auxiliary precipitating bottle side, and the escape pipe is connected with the sucking pump; the welding waste gas treatment unit for semiconductor device manufacturing can effectively ionize and decompose the high-temperature exhaust gas produced from the welding furnace, and can more effectively process the rosin compositions in the high-temperature exhaust gas through the dual effect of the ionization bar and the air casing, so as to reduce environmental pollution caused by waste gas emission.

Description

technical field [0001] The invention relates to a welding waste gas treatment device for manufacturing semiconductor devices, and belongs to the technical field of waste gas discharge treatment. Background technique [0002] At present, semiconductor device companies often use automatic welding equipment. The main component of the flux used in welding equipment is rosin. Rosin will generate a large amount of waste gas after heating. If the waste gas is not collected and treated in a centralized manner, it will not only pollute the atmosphere, but also affect people. health. However, most of the current rosin factories simply collect the waste gas and discharge it directly into the atmosphere without any treatment, thus causing serious air pollution. How to overcome the above technical problems has become the direction of efforts of those skilled in the art. Contents of the invention [0003] The purpose of the present invention is to provide a welding waste gas treatment ...
