Abstract
The utility model relates to the field of pulping and papermaking auxiliary equipment, in particular to a cooling device for quickly cooling dilute black liquor, which is formed by a stepped frame and a trough. The cooling device is technically characterized in that the stepped frame is exposed in the air and in a multi-step shape, and the trough is arranged below the stepped frame and used for collecting black liquor retained in the stepped frame. When a machine is started for pulping extraction, partial extracted dilute black liquor passes through a liquor inlet pipe to flow on the stepped frame so as to be cooled, and cooled dilute black liquor is collected in the trough and used for pulping ejection prior to being output through a dilute black liquor outlet pipeline.
Description
Technical field
The utility model relates to pulping and paper-making auxiliary equipment field, a kind of specifically cooling device that is used for rare black liquor fast cooling.
Background technology
At present, the rare black liquor that adds when the continuously cooking slurry spurts, be to handle by single sealed water-cooled cooler, water consumption is big, and the rare black liquor temperature after it is handled is generally all more than 70 ℃, and slurry viscosity is big when causing spurting, flow velocity is slow, cause and spurt not freely, even stop up the extraction of unfavorable next process slurry, bleaching.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, a kind of cooling device that is used for rare black liquor fast cooling is provided, this device is the stepped air-cooled cooler of open type, and the temperature of having guaranteed rare black liquor of being used to spurt reduces the viscosity of spurting of slurry below 45 ℃.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of cooling device that is used for rare black liquor fast cooling is provided, and this device is made up of ladder framework, cell body.Technical characterictic of the present utility model is: rank body framework is exposed in the air, and is stepped, and cell body is collected the black liquor that the ladder framework stays below the ladder framework.
The beneficial effects of the utility model are, adopt the stepped cooler of open type, utilize air-cooled, saved water resource, film-cooled heat is big, and the energy fast cooling is used in the rare black liquor temperature that spurts and can reduces to below 45 ℃ fast, help spurting slurry viscosity and reduce, thereby guarantee that slurry is unblocked in the pipeline circulation.
Description of drawings
Figure is a structural representation of the present utility model.
1. ladder frameworks among the figure, 2. feed tube, 3. rare black liquid outlet pipeline, 4. cell body
The specific embodiment
The utility model device is made up of ladder framework 1 and cell body 4, it is characterized in that rank body framework 1 is exposed in the air, is multistage scalariform, and cell body 4 is collected the black liquor that ladder framework 1 stays below ladder framework 1.When start is extracted in slurrying, extract the rare black liquor of part and on ladder framework 1, cool off by feed tube 2 streams, cooled rare black liquor collects in the cell body 4, by rare black liquid outlet pipeline 3 outputs, spurts use for slurry.
Claims (1)
1. cooling device that is used for rare black liquor fast cooling, be made up of ladder framework (1), cell body (4), it is characterized in that: rank body frameworks (1) are exposed in the air, and are stepped, cell body (4) is collected the black liquor that ladder framework (1) flows down below ladder framework (1).
