Description
Изобретенне относитс к снособа.м регулировани уровн суспензни в ваннах барабанных вакуум-фильтров в процессе нромывкн це.тлюлозы и нредназначено дл использовани в целлюлозно-бумажной промышленности.The invention relates to a method for adjusting the level of the suspension in the baths of drum vacuum filters in the process of pulp washing machines and is intended for use in the pulp and paper industry.
Известен способ регулировани уровн суснензпи , основанный на изменении числа оборотов барабанов фильтра.There is a known method for adjusting the level of suspension, based on a change in the speed of the filter drums.
Однако этот способ не обеспечивает эффективности работы фильтров и вызывает изменение времени пребывани массы в зоне проМЫВ .КИ.However, this method does not ensure the efficiency of the filters and causes a change in the residence time of the mass in the washed-out zone.
Известен другой способ регулировани уровн суспензии в ваннах барабанных вакуумфильтров промывной установки, заключающийс в измерении уровн суспензни в ванне фильтра п в поддержании его значени в заданных пределах.There is another method of controlling the level of the suspension in the baths of the drum vacuum filters of the washing installation, which consists in measuring the level of the suspension in the filter bath and in maintaining its value within the specified limits.
Этот способ оспован па изменении нодачи суспензии на фильтрацию. Однако это вызывает измепеппе производительности иромывиой установки, что требует перестройки всех участков процесса производства целлюлозы или ирпменепие значительных буферных емкостей , что в конечном ито1е сказываетс на ироизводптельпостп.This method is mastered by changing the suspension's flow rate to filtration. However, this causes a change in productivity and the installation of a washing machine, which requires restructuring of all parts of the pulp production process or the application of significant buffering tanks, which ultimately affects the performance of the plant.
Цель изобретепи - поддержание посто нной максимально возможной производительности .The goal of the invention is to maintain a constant maximum possible performance.
Это достигаетс тем. что поддержание уровп суспепзпп осуществл етс путе.м измепени подачи фильтрата, идуп1,его па разбав;1еиие с}спензнн. This is achieved by those. that the maintenance of the level of the suspension is carried out by measuring the supply of the filtrate, idup1, to dilute it;
Супдность снособа заключаетс в том, что регулнрованпе уровн осупкчтвл ют путем изменени относительной доли фильтрата, иодавае .мого на разбавление с спепзпп в начальпой вапие и осадка в промежуточных ваннах ваку)м-фильтров, что позвол ет поддерживать носто нно максимальную производительность промывной установки. Относительное количество фильтрата, которое потребуетс иа регулирование уровн в ванне, на пор док меньн е обп1,его расхода фильтрата, подаваемого па разбавление, п не ВЕ зовет пзмепеппе копцеитарции в ванне бо.чьHie , чем на 1 ,и от номнна.тьного зиачепп .Sufficiency is removed by adjusting the level by varying the relative fraction of the filtrate, iodine through dilution from specimen to the base of the vapia and sediment in the intermediate baths of the m-filter, which helps maintain the maximum capacity of the washing unit. The relative amount of filtrate that will be required for level control in the bath, as much as possible, its flow rate of the filtrate supplied to the dilution, does not mean that the sample in the bath will be higher than in 1, and from each other.
