Description

A waste water decalcification device for water quality online monitoring instrument

technical field

The utility model relates to the field of water quality on-line monitoring equipment, in particular to a wastewater decalcification device used for water quality on-line monitoring equipment.

Background technique

The water quality online monitoring instrument is an instrument for online monitoring of pollutant content in natural water and various industrial drainage and other water bodies. When the water quality online monitoring instrument monitors high-calcium wastewater, the high-concentration calcium ion in the wastewater reacts with the detection and analysis reagent to produce precipitation, which causes the blockage of the pipelines of each unit of the instrument, resulting in the failure of the monitoring instrument to work normally, which greatly affects the accuracy of the monitoring data. And increased the maintenance frequency and workload of the instrument, shortened the service life of the instrument.

Contents of the invention

The purpose of this utility model is to provide a decalcification device for wastewater used in online water quality monitoring instruments. The decalcification effect of the device meets the requirements of the online water quality monitoring instrument for decalcification of sampled water.

The technical solution of the utility model is, a wastewater decalcification device used for water quality on-line monitoring instruments, including a reaction tube (7) and a tube cover (2). The upper side of the reaction tube is a frosted nozzle, and the lower side is provided with a drainage port, and the pipe wall is respectively provided with an overflow port, a water inlet and a sampling port from top to bottom; the reaction tube (7) passes through the frosted nozzle (3) and the tube wall. The cover (2) is connected; the drain port (8) is connected with a solenoid valve through a pipe; the overflow port (4) is inclined downward, the water inlet (5) is inclined upward, and the sampling port (6) is horizontal, respectively from top to bottom The bottom is laid on the tube wall; the tube cover (2) is designed with a ground mouth, and has a liquid inlet (1), and the liquid inlet (1) is connected to the sodium carbonate reagent (9) through a pipeline.

The inner wall of the reaction tube has a smooth surface, and the tube cover is also designed with a ground mouth, and has a liquid inlet.

Both the reaction tube and the tube cover of the decalcification device have a one-to-one frosted interface.

The advantages of this utility model are:

1. This utility model meets the requirements of online water quality monitoring instruments for decalcification of sampled water quality.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, further elaborate the utility model.

Fig. 1 is a schematic structural diagram of a waste water decalcification device used in an online water quality monitoring instrument of the present invention, including a reaction tube (7) and a tube cover (2). The reaction tube (7) is connected to the tube cover (2) through the frosted nozzle (3); the drain port (8) is connected with a solenoid valve through a pipe; the overflow port (4) is inclined downward, and the water inlet (5) is upward Inclined, the sampling port (6) is horizontal, respectively arranged on the tube wall from top to bottom; the tube cover (2) is designed with a ground mouth, and has a liquid inlet (1), and the liquid inlet (1) passes through the pipeline Connect with sodium carbonate reagent (9).

The water sample to be tested enters the inside of the reaction tube (7) through the water inlet (5) after being pumped by the sampling pump. The liquid level is higher than the sampling port (6). 1) Enter the reaction tube (7), the high concentration of calcium ions in the water sample react with sodium carbonate and precipitate to the bottom of the tube, the water sample located above the sampling port (6) can be used for water detection by the online water quality monitoring instrument, and the sediment at the bottom of the tube passes through the solenoid valve The control can be discharged from the outlet (8) to the outside of the reaction pipe (7), thereby ensuring the requirement of the online water quality monitoring instrument for decalcification of the sampled water, and effectively solving the interference of high-concentration calcium ions on the online water quality monitoring instrument.
