PARALLEL CIRCUIT FOR TREATMENT WITH FILTRATION OF SUSPENSION OR EMULSION AND DEVICE WITH THIS CIRCUIT Russian patent published in 1998 - IPC

FIELD: treatment with filtration of suspensions or emulsions. SUBSTANCE: circuit has two parallel self-cleaning filters whose inlets are interconnected through three-way distributor, and filtrate outlets are interconnected by means of the other three-way distributor. Distributors are made for changing in antiphase of flow rates of filtered medium through filters without stopping the process of washing the filter surface, successively, by separate sections and by means of reverse flow of filtrate. As a result, regeneration of filters is improved. The device for treatment with filtration of suspension or emulsion has pump for supply of treated medium connected with system for treatment with filtration of suspension or emulsion. The system is connected with user of filtrate made for its use with nonuniform distribution of operation time under different operating conditions affecting physical parameters of filtrate and/or treated medium. The system is made in form of parallel circuit for treatment with filtration of medium in which control of change of flow rate of filtered liquid in antiphase through self-cleaning filters is effected with use of, at least one physical parameter of filtrate and/or filtered medium. EFFECT: improved treatment of suspension or emulsion and filter regeneration due to use of nonuniform statistical distribution of duration of operation of filtrate user under different operating conditions. 25 cl, 10 dwg
