Drum type black liquor extractor

Equipment Introduction/Equipment Features

QK-SERIESDrum type black liquor extractorA product independently developed by the company based on years of practice. Mainly used for black liquor extraction, drifting pulp concentration, and waste paper thermal dispersion in the pulp washing section of the paper industryThick. Solid liquid separation in industries such as black liquor extraction, washing, concentration, printing and dyeing in the chemical fiber pulp industry.

1. High black liquor extraction rate: The single-stage black liquor extraction rate can reach 75%, the two-stage series can reach 85%, and the three-stage series can reach over 90%;

2. High pulp dryness: The pulp dryness is 8-10% higher than that of the screw extruder, reaching up to 30-45%;

3. Energy saving effect: The power consumption is 1/6 of that of a screw extruder of the same production scale, saving over 200000 yuan in electricity costs per unit annually;

4. Low investment, simple installation, easy operation, no noise, and minimal maintenance.

Secondary series connection

1QK-SERIESDrum type black liquor extractorFor high concentration extraction equipment, it can be used alone, in series, or in combination with low concentration extraction equipment, such as vacuum washer, horizontal belt washer, and spiral mesh belt washerThe machine can complement each other's advantages and achieve better results, increasing the extraction rate by 5 percentage points and significantly reducing the COD load of the middle water by more than 10%.

2. As a high concentration energy-saving dehydration equipment, this machine is more suitable for dehydration of slurry before thermal dispersion, which can save 15% of steam consumption and electricity consumption, significantly improving the thermal dispersion effect.

3. The dryness of cotton pulp produced by this machine can reach 40%, wood pulp 35%, bagasse pulp 35%, and straw pulp 33%. Therefore, it can be widely used in professional pulp companies to save transportation costs and reduce costs.
