- the invention is available for the processing of bulk chemicals with a chemical reagent and for a quick start for its maintenance>. It may be used in the pulp and paper industry for the treatment of cellulose with a reagent.

- a fair way can be used in other household products of a cellulose by a gas reagent.
- the main drawback of the known system is the ⁇ . ⁇ . that it does not provide for a sufficiently intensive intensive mass exchange in the recycled zone and the equal separation of the reagent for the entire mass layer.
- the consequence of this is the low coefficient of use of the reagent and the low quality pulp produced ;. the degree of whiteness does not exceed 55%).
- This invention is directed to the creation of a high ⁇ effective method of processing the Great masses. chemical reagent. Providing an equitable processing of the material for the whole of the general layer of the reactive mass, a decrease in the cost of the reagent, a high-quality mass; . in particular - an increase in the degree of whiteness of the pulp mass _, as well as the possibility of treating the free mass of the pulp by the high use of non-vascular pulp. both in the gas and in the liquid sector.
- the delivered task is resolved by first and secondly mixing of a great mask with a gas-based ' agent ' in the chamber of the mixture with the above mixture. - 3 -

- the chemical product used in the process may provide gas, for example. acid ozon or cold.
- Such liquids and liquids for example, are water discharges of chlorine dioxide or liquid.
- a chemical reagent can be used as a natural gas product, and it is also beneficial to use and transport agent.
- a part of the gaseous chemical reagent is supplied to the mixing chamber as a random agent and the mixture obtained is transformed into the mixture.
- the proposed methods make it possible to process a high-grade fiber mass with an absolute absolute value of matter? ⁇ ⁇ 90% wt.
- devices are provided for delivering a wafer of mass, a mixing chamber, and a means for supplying a gas reagent.
- the store ' is equipped with beds for the delivery of a reagent, located at a length of 4.
