Multi-channel cation bed sodium ion alkalization system Technical Field

[0001] This utility model relates to the field of water pretreatment technology, and in particular to a multi-channel cation bed sodium ion alkalization system. Background Technology

[0002] A cation exchange bed sodium alkalization system is a system specifically designed to treat effluent from a cation exchange bed, increase the pH value of the water sample, and thus ensure the accuracy of sodium ion measurement. Existing alkalization systems have the following drawbacks: 1. Low processing efficiency: Most adopt a single-channel design, requiring separate equipment deployment when different sampling points are needed, leading to increased costs, large equipment footprint, and low efficiency. 2. Existing alkalization devices mostly use a straight-pipe mixing structure, resulting in insufficient contact time between the water sample and the alkalizing agent, leading to unstable pH increases and low detection accuracy. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, this utility model aims to provide a cation bed sodium ion alkalization system with multi-channel synergistic processing and high control precision.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Preferably, the detection module includes a pH sensor to detect the pH value of water samples in each channel in real time; and a conductivity sensor to monitor the change in conductivity of the water sample after alkalization, which is used to assist in verifying the elimination effect of H+ interference.

[0007] Preferably, each of the water sample processing channels is equipped with a flow sensor.

[0008] Preferably, each water sample treatment channel is equipped with a waste liquid discharge outlet.

[0009] Preferably, the diffusion-type alkalization device uses a honeycomb diffusion tube equipped with a permeation membrane and also includes a peristaltic pump.

[0010] Preferably, the permeation membrane is made of polytetrafluoroethylene (PTFE).

[0011] Compared with existing technologies, this invention has the following advantages: 1. By using multi-channel water sample treatment and switching channels to eliminate interference between channels, the application range is greatly improved, and the number of channels can be dynamically expanded; 2. Through the structural design of the diffusion-type alkalization device (honeycomb structure combined with a permeable membrane), the contact surface of the alkalizing agent is increased, and the alkalization time is shortened; 3. The use of polytetrafluoroethylene material increases the service life. Attached Figure Description
