FLOW SHEET PULP AND PAPER MANUFACTURING

washing down tanks and floors after spills, paper break or for general cleaning, the nature of paper pulp is such at this point that relatively hot water in a high velocity stream greatly expedites the work of dislodging and washing away the pulp A typical application is an S&K Figure 320 heater to supply hot water hoses on machine room floors

Blow Tank an overview | ScienceDirect Topics

The heat of the hot gases from the blow tank is recovered by the blow heat accumulator, a large heat exchanger Up to 1000 kg (2000 lb) of steam per ton of pulp is generated by batch digesters and some continuous digesters and must be condensed Continuous digesters such as the Kamyr are able to recover the heat more efficiently by liquor

Digester blow tanks | Magnetrol

In batch digestion, the pulp and black liquor are mechanically conveyed or "blown" into an atmospheric blow tank upon completion of the cooking cycle The tank is a large cylindrical vessel which functions as intermediate storage of the cooked pulp, and from which the pulp (now called "Brown Stock" due to its color) is discharged in an even flow to a washing process
