Automatic-purging accurate-statistics ammonia removal maintenance system for electrolytic electroplating plant

Abstract

The invention relates to an automatic-purging accurate-statistics ammonia removal maintenance system for an electrolytic electroplating plant. A wind parameter maintenance system having a regular automatic purging function, reliable performances and a blast capacity accurate-statistics function realizes regular purging of a wind parameter measurement tube through integrated installation and signal transmission modules so that accurate measurement of wind parameters at any time is guaranteed. A timing relay accurately controls purging frequency so that stable purging is guaranteed and system reliability is improved. A second solenoid valve realizes isolation protection of a pressure transmitter and a GPRS signal transmission module so that system stability is improved. A signal amplifier circuit mainly comprising a first operational amplifier carries out filtering and amplification on a sampled signal so that signal sampling reliability is improved and thus system operation accuracy and reliability are improved. A biasing circuit mainly comprising a second operational amplifier carries out signal bias so that later sampling chip reliability to signal detection and analysis is guaranteed and accurate detection and analysis of the signals are improved. A device material is reinforced polypropylene RPP and is used for improving device corrosion resistance and reducing ammonium sulfate crystals on the device.

Description

technical field [0001] The invention relates to an accurate statistical ammonia removal maintenance system for automatic purging in an electrolytic electroplating factory. Background technique [0002] With the continuous development of national environmental protection, new challenges have been put forward for the environmental protection work of traditional industries such as power generation enterprises, chemical enterprises, electrolytic plating enterprises, etc., and the emission standard measurement requirements for these enterprises are also more stringent. [0003] But at present, many electrolytic plating enterprises directly show that the ammonia pollution in their factories is serious and the smell is pungent. Parameters such as air pressure, air flow, and gas content in the exhaust cannot be measured continuously and accurately. The most obvious contradiction is that the harsh measurement environment with a lot of dust, high humidity, corrosiveness, and easy crys...
