1. Brief Introduction
Chlorination stage in pulp bleaching(Segment C), The thorough, rapid, and even mixing of pulp is crucial for enhancing pulp brightness and ensuring product quality. Poor mixing leads to uneven pulp contact, inevitably causing uneven chlorination. To improve chlorination effectiveness, a pulp-chlorine mixer must be installed.
The slurry-chlorine mixer boasts simple operation, excellent mixing results, low energy consumption, minimal investment, and corrosion resistance. It is a high-performance, low-concentration slurry-chlorine mixing equipment with a high market share in the domestic market today.
2. Structure and Principle
The ZLK series slurry-chlorine static mixer is composed of three parts: a chlorine water dispersion mixer, a slurry-chlorine distributor, and an MK-type static mixer. It integrates jet pump technology and static mixer technology, offering reliable performance, long service life, and excellent mixing results, reaching the technical level of similar products at home and abroad. It has been widely used in numerous paper mills across China.
The MR type chlorine water dispersing mixer is a small device utilizing jet technology. The impact of the jet stream crushes and disperses the vacuum-suctioned material into fine bubbles, which are then mixed and dissolved in water to form a basically homogeneous chlorine water. It is subsequently neutralized through a slurry chlorine distributor and mixed rapidly with the slurry in the MK type static mixer.
The MK type static mixer is a tubular device primarily composed of several spiral plate mixing elements fixed inside the tube and an external shell. It generates cutting, shearing, rotation, and recombination of two or more streams of fluid entering the tube body, resulting in an efficient radial circulation mixing action. This action achieves excellent dispersion and thorough mixing of pulp and chlorinated water.
3. Excellent corrosion resistance Due to the bleaching section of the pulp processingSection C) The equipment is exposed to a highly complex corrosive environment, featuring not only high acidity but also high levels of chloride ions, making it extremely corrosive. Selecting the appropriate corrosion-resistant materials is crucial for ensuring the long-term use of the equipment. Through years of practical experience, our company has developed three excellent corrosion-resistant material configurations, guaranteeing long-term usage for our customers. |

5. Installation and Use
The installation location and piping method of the slurry-chlorine static mixer are crucial for reducing chlorine consumption and enhancing chlorination efficiency. Generally, the slurry-chlorine static mixer is installed in...On floors 6-12 meters high, ensure the slurry processed through the mixer enters the bottom of the upflow chlorination tower as quickly as possible. Preferably, the continuous pipeline between the slurry-chlorine mixer and the chlorination tower should be short to facilitate rapid and thorough mixing of the slurry within the chlorination tower.
The ZLK type static slurry chlorine mixer consists of components all connected by flanges, with the standard flange typically following HG/T20592-2009. Custom configurations are also available according to customer requirements.
