Abstract

The invention relates to a device, a circuit and a method for detecting the liquid level of a nitric acid storage tank. The device comprises a nitric acid storage tank, a nitric acid storage tank inlet pipe (9) and a nitric acid storage tank outlet pipe (10), and is characterized in that: a liquid level detection device is arranged on the nitric acid storage tank. In the invention, the liquid level of the nitric acid storage tank can be displayed on site according to the position of a metal balance counter weight, so that the problems of unsafe factors and labor which exist during manual measurement of the liquid level of the nitric acid storage tank when necessary in the prior art are solved.

Description

technical field [0001] The invention relates to a liquid level detection device, a detection circuit and a detection method, in particular to a nitric acid storage tank liquid level detection device, a detection circuit and a detection method. Background technique [0002] The dehydration station of Dahongshan Pipeline Company must use nitric acid due to the production equipment process requirements, and the amount of nitric acid is large, so the dehydration station uses two HDPE plastic nitric acid storage tanks with a capacity of 30 tons to store 50% - 65% of the nitric acid to meet the cleaning requirements. The ceramic filter needs to clean the ceramic plate of each ceramic filter after 7 hours of operation. The cleaning method requires the use of 60% nitric acid. The cleaning time of each device is about 40 to 50 minutes. The amount of nitric acid cleaning is large, so Nitric acid needs to be stored in two storage tanks with a capacity of 30 tons. [0003] Because the ...
