FIELD: woodworking industry.
SUBSTANCE: water medium, which comprises cooking base, is treated with gas mixture that contains sulfur dioxide. For this purpose device is used with tangential supply of water medium, which is equipped with porous element that separates it internal space into two longitudinal cavities. Gas mixture is supplied along one side of element and further to water medium through its pores under pressure of 0.6-1.2 MPa, and water medium is supplied along another side of element under pressure that is 0.04-0.06 MPa lower than pressure of gas mixture. Water medium is supplied in the form of main and additional flows. Water medium after its treatment with gas mixture is exposed to floatation cleaning with application of inertial gaseous part of processing products as flotator. Blower products from cooking boilers are supplied into water medium in process of its floatation cleaning.
EFFECT: increased efficiency of process and simplified process.
