Description

Stable online nitrate nitrogen detection improvement device

Technical Field

The utility model relates to a stable online nitre nitrogen detection improvement device.

Background

Normally and generally detecting the nitrate nitrogen concentration is to detect the nitrate nitrogen concentration at an output end of sewage treatment, but in order to improve the qualification rate of the detection value of the nitrate nitrogen concentration at the output end of the sewage treatment, a detection probe is added in the middle of the sewage treatment to detect the middle-stage water flow in the sewage treatment process; however, the traditional detection probe is arranged in the reaction tank and is influenced by water flow impact and aeration floating suspended matters, so that the measured value of the detection equipment is abnormally fluctuated, the detection is unstable, and the detection result is influenced; meanwhile, the detection probe is easy to pollute and inconvenient to clean.

SUMMERY OF THE UTILITY MODEL

The utility model discloses improve above-mentioned problem, promptly the to-be-solved technical problem of the utility model is to provide a stable online nitre nitrogen detects improvement device, simple structure and convenient to use can detect rivers under the relatively stable state, can prevent that the short current from causing the damage to test probe simultaneously.

The utility model discloses a constitute like this, it includes inlet tube, aqueduct and the test tube that sets gradually along rivers direction of intaking, the test probe who is used for measuring nitre nitrogen content in the rivers is installed to the top in the test tube, the side is provided with the overflow mouth on the test tube, the aqueduct is close to the vertical liquid level pipe that is equipped with of aqueduct input, the vertical setting of test tube just is connected with the aqueduct output, test tube, aqueduct and liquid level pipe form U type tubular construction, and the aqueduct middle part is provided with the check valve.

Furthermore, the two sides of the one-way valve are provided with emptying pipes communicated with the water guide pipe, and each emptying pipe is provided with a valve switch.

Furthermore, the outside of the overflow port is connected with a drain pipe.

Furthermore, a sealing cover is arranged at the upper end of the liquid level pipe.

Further, the diameter of the detection pipe is larger than that of the water guide pipe.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses simple structure, reasonable in design compares traditional installation device, can effectively avoid the check out test set to receive the influence of water impact and partial come-up suspended solid, and the measuring value of nitro-nitrogen is relatively stable and fine maintenance test probe submergence in the aquatic under the condition of short-term flow in the rivers, and easy washing is maintained simultaneously, and outlet around the check valve can be used to the sample to compare and wash evacuation, and is with low costs.

in the figure: 1-water inlet pipe, 2-water guide pipe, 3-detection pipe, 4-detection probe, 5-overflow port, 6-liquid level pipe, 7-one-way valve, 8-emptying pipe, 9-valve switch, 10-drain pipe and 11-sealing cover.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Example (b): as shown in fig. 1-3, a stable online nitrate nitrogen detection improvement device is provided, including inlet tube 1, aqueduct 2 and the test tube 3 that sets gradually along rivers direction of intaking, the top is installed and is used for detecting the measuring probe 4 of nitrate nitrogen content in the rivers in the test tube, the side is provided with the overflow mouth on the test tube, the aqueduct is close to the vertical liquid level pipe 6 that is equipped with of aqueduct input, the vertical setting of test tube just is connected with the aqueduct output, the test tube, aqueduct and liquid level pipe form U type tubular construction, and the aqueduct middle part is provided with check valve 7.

The hydrostatic balance principle and the high-level overflow adopted by the U-shaped pipe structure ensure that the water flow in the device is in a relatively stable state and can effectively protect the detection equipment under the condition of short flow.

The setting of check valve can avoid the rivers backward flow through the check valve, causes test probe can't soak in the rivers, causes unable test probe to damage.

In order to facilitate cleaning and emptying, emptying pipes 8 communicated with the water guide pipe are arranged on two sides of the one-way valve, and each emptying pipe is provided with a valve switch 9; when sampling, the valve switch is opened, and the internal water flow on two sides of the one-way valve can be sampled and compared.

The outside of the overflow port is connected with a drain pipe 10; when the water level in the detection pipe is too high, water flow can be discharged to the drain pipe from the overflow port, and the height stability of the water level in the overflow pipe is ensured.

The upper end of the liquid level pipe is provided with a sealing cover 11, and the sealing cover can be opened to observe the height of the water level inside the liquid level pipe.

The diameter of the detection pipe is larger than that of the water guide pipe.

The detection probe can be a nitrate nitrogen online monitor.

Any technical solution disclosed in the present invention is, unless otherwise stated, disclosed a numerical range if it is disclosed, and the disclosed numerical range is a preferred numerical range, and any person skilled in the art should understand that: the preferred ranges are merely those values which are obvious or representative of the technical effect which can be achieved.
