Double-tower double-spray waste gas treatment device for PCB production

Abstract

The invention discloses a double-tower double-spray waste gas treatment device for PCB production. The device comprises a device base, a waste gas filter chamber, a gas inlet pipe, a gas return pipe and a telescopic column; the waste gas filter chamber is installed on one side of the top end of the device base, a waste gas guide cylinder is fixed to the center in the waste gas filter chamber, an ultraviolet decomposition chamber is installed in the center of the top end of the device base through a support boss, a first washing spray tower and a second washing spray tower are installed on theside walls of the two ends of the ultraviolet decomposition chamber respectively, a waste gas check instrument is installed at the device base top end on the side, away from the ultraviolet decomposition chamber, of the second washing spray tower through a support table, and an activated carbon adsorption chamber is installed at the end, away from the waste gas filter chamber, of the device base.The device improves the uniformity in the washing spray process, achieves the waste gas filtering function and avoids environmental pollution.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a double-tower and double-spray waste gas treatment device for PCB board production. Background technique [0002] PCB circuit board, also known as printed circuit board, is a provider of electrical connections for electronic components. Its development has a history of more than 100 years. Its design is mainly layout design. The main advantage of using circuit boards is that it greatly reduces wiring and Assembly errors improve the automation level and production labor rate. However, the process of PCB board production is always accompanied by the generation of a large amount of waste gas. For the treatment of waste gas, the traditional method is to pump the waste gas into the liquid medicine tower for direct processing. Filter the chemical reaction and then discharge. Since the waste gas in the tin spraying process in PCB production contains a lot of smoke and dust,...

[0002] PCB circuit board, also known as printed circuit board, is a provider of electrical connections for electronic components. Its development has a history of more than 100 years. Its design is mainly layout design. The main advantage of using circuit boards is that it greatly reduces wiring and Assembly errors improve the automation level and production labor rate. However, the process of PCB board production is always accompanied by the generation of a large amount of waste gas. For the treatment of waste gas, the traditional method is to pump the waste gas into the liquid medicine tower for direct processing. Filter the chemical reaction and then discharge. Since the waste gas in the tin spraying process in PCB production contains a lot of smoke and dust, the one-layer recovery filter tower cannot completely absorb the harmful gas in the waste gas, which may cause harm to the atmospheric environment after discharge, and many waste gas treatment The device is not equipped with the filtering function of solid particles before the treatment, which greatly reduces the treatment effect of the exhaust gas, and even some exhaust gas treatment devices are not equipped with the detection of the exhaust gas, thus causing environmental pollution
