Pulp bleaching of the paper machine requires a bleaching machine. The bleaching machine is a commonly used bleaching equipment. It consists of a bleaching tank screw propeller, drum washing and other components.
In the production process of the paper machine, the pulp and bleach need to be placed in the tank, and the washing water is continuously added, and the continuous circulation flow in the tank is formed in the production line by the action of the screw propeller, and then all the mixing and chemical reaction are completed After the chemical process is completed, the water and bleaching products with residual bleach are discharged through the inner cavity of the washing drum to obtain white pulp.
