Product Overview

This 10%-15% sodium hypochlorite generator uses ion-exchange membrane brine electrolysis technology, stably producing sodium hypochlorite solution with 10% to 15% effective chlorine concentration, the whole unit is integrated on a standard skid, equipped with full-automatic PLC touch control system. All pipelines and liquid storage tanks are made of anti-corrosion CPVC and 316L stainless steel.

System Technological Process

The whole production flow of the 10%-15% sodium hypochlorite generator adopts closed-loop automatic circulation, divided into 6 standardized continuous working sections, each link with online monitoring sensors to ensure stable liquid concentration output:

1. Saturated Brine Preparation Unit

Industrial refined salt is put into the salt dissolving tank, tap water is automatically added according to the liquid level sensor, stirring equipment continuously mixes to prepare saturated brine (25% NaCl concentration). The system automatically supplements salt and water when brine liquid level is low.

2. Multi-stage Precision Filtration Section

Saturated brine is transported by anti-corrosion pump into two-stage precision filter. The primary filter removes coarse salt residues and suspended impurities, the secondary fine filter intercepts calcium and magnesium ions precipitates, extend core electrode service life.

3. Constant Flow Brine Dosing & Buffer

Purified saturated brine flows into the buffer tank, the flowmeter transmits real-time data to PLC control cabinet, the metering pump stably delivers fixed-flow brine into each electrolytic cell group.

4. Ion Membrane Electrolysis Core Reaction

Brine enters sealed ion-exchange membrane electrolytic cell, stable DC current output by high-efficiency digital rectifier triggers electrolytic reaction. The ion membrane separates anode and cathode areas: chlorine gas generates on anode, sodium hydroxide forms on cathode. Two substances fully circulate and react inside the closed absorption tower, generating 10%-15% high concentration sodium hypochlorite stock solution. Hydrogen by-product is collected by sealed pipeline and safely diluted & exhausted outdoors after explosion-proof treatment.

5. Concentrated Liquid Storage & Automatic Dosing

Freshly produced high-titer NaClO liquid automatically flows into anti-corrosion concentrated liquid storage tank, equipped with liquid level alarm and constant temperature protection to slow down solution decomposition. The system supports automatic quantitative dosing linkage with external water circulation pipeline, real-time adjusting disinfectant adding volume based on online residual chlorine detector signal.

6. Automatic Online Pickling Maintenance Loop

The system reserves independent acid washing pipeline loop. When electrode scaling affects electrolysis efficiency, the PLC automatically starts the pickling program: dilute hydrochloric acid circulates inside electrolytic cell to remove carbonate scaling, no need to disassemble the cell manually, greatly reducing equipment maintenance labor cost.

Wide range of application industries and scenarios

Frequently Asked Questions

Question 1: What is a high-concentration sodium hypochlorite production unit?

A: The high-concentration sodium hypochlorite unit is an electrochemical system that produces a 10-15% sodium hypochlorite solution by electrolyzing purified brine, providing a safe alternative for transporting commercial bleaching agents.

Q2: What purity of salt do we need? Can we use low-grade salt from Africa?

A: Our equipment only supports industrial salt with a purity of ≥89%, eliminating the need for high-purity refined salt with a purity of ≥95%. Locally sourced African sea salt/mineral salt can be used directly, significantly reducing overseas raw material procurement and logistics costs.

Q3: How much salt and electricity is consumed per ton of 15% sodium hypochlorite solution?

A: Standard benchmark: Producing 1 kg of available chlorine requires 1.9 kg of salt and 2.8 kWh of DC electricity. Taking the BSHH-2200 (chlorine output 10 kg/hour) as an example, it consumes 18 kg of salt and 23 kWh of electricity per hour. We can calculate the accurate daily operating cost based on your local salt and electricity prices.

Q4: Is this equipment skid-mounted? How long will it take to complete installation and commissioning after delivery?

A: All standard models feature an integrated skid-mounted plug-and-play design; containerized mobile equipment can also be customized. Once the goods arrive on site, only water, electricity, and salt lines need to be connected. Our technical engineers will complete all commissioning within 1-3 days under your guidance.

Q5: Can a single machine simultaneously produce a 5% dilute NaClO solution and a 15% high-concentration NaClO solution?

A: Yes. The BSHH series products support stepless concentration adjustment from 5% to 15% through an intelligent PLC system. One set of equipment can meet two production needs: diluting disinfectant for drinking water and high-concentration stock solutions for daily chemical raw materials, avoiding the investment of two production lines.

Q6: Do you provide on-site service for projects in Africa? What is the warranty period?

A: We collaborate with local technical engineers to provide on-site installation, commissioning, and operator training for our African customers. The entire unit comes with a 12-month warranty, and the core membrane electrolyzer enjoys an extended warranty. We offer 24/7 global remote online troubleshooting support year-round.

Q7: Besides NaClO, what other chemical substances can this plant produce?

A: This integrated system can simultaneously produce chlorine, sodium hydroxide (caustic soda), hydrochloric acid, and sodium chlorite. These products can be used for in-plant production or sold independently as chemical raw materials.
