Problems solved by technology

Looking at the existing real-time monitoring technology and equipment, there are problems that the timely and effective replenishment of the eluent cannot be solved, and the concentration of the eluent cannot be effectively controlled after regeneration. Therefore, the amount and concentration of the eluent must be manually replenished and monitored frequently. If the amount of eluent is not effectively replenished, and the concentration is not well controlled, it will lead to inaccurate monitoring results in light cases, and lose the significance of monitoring in severe cases

Abstract

The invention discloses an acid deposition online monitoring system, comprising an automatic sampler, a six-way valve, a separation column, a suppresser, a conductivity detector, a data processor, an elute bottle, a high pressure pump, a water tank and a concentration monitoring meter, wherein the automatic sampler is connected with the six-way valve; the elute bottle is connected with the high pressure pump, the six-way valve, the separation column, the suppresser, the conductivity detector and the data processor in sequence; the water tank is connected with the elute bottle by using a metering pump; the conductivity detector is in bidirectional connection with the suppresser; the concentration monitoring meter is arranged in the elute bottle; and the suppresser is provided with a an elute recovering pipeline communicated with the elute bottle. The acid deposition online monitoring system provided by the invention not only can effectively supply spraying liquid but also can further ensure the concentration of the spraying liquid to be accurately monitored in real time according to the concentration variation of the spraying liquid, so that the frequency of supplying the spraying liquor can be effectively reduced, and the online monitoring precision is improved in real time.

Description

Technical field [0001] The invention specifically relates to an online monitoring system for acid deposition, which belongs to the field of environmental monitoring. Background technique [0002] The monitoring of acid deposition (acid rain) currently uses sampling monitoring methods, that is, collecting acid rain in different environments and then taking it to the laboratory for ion chromatography. This is not only time-consuming and laborious, but also particularly important because the nature of acid rain after sampling The real-time situation changes, which will cause the final detection result to be different from the real-time sampling result, thereby reducing or losing the significance of monitoring. [0003] At present, real-time monitoring is also adopted in the industry. The real-time monitoring of acid precipitation is inseparable from the eluent. The main components of the eluent are sodium carbonate and sodium bicarbonate, which will be consumed during use, so it mus...
