Description

(54) СПОСОБ АВТОМАТИЧЕСКОГО УПРАВЛЕНИЯ РАБОТОЙ ФИЛЬТРА(54) AUTOMATIC OPERATION METHOD OF OPERATING FILTER

Изобретение относитс  к способам автоматического отключени  фильтров при локальных разрывах сеток и может быть использовано при автоматизации процесса очистки воды в системах водоснабжени  и канализации.The invention relates to methods for automatically shutting off filters during local grid breaks and can be used to automate the process of water purification in water supply and sewage systems.

Известен способ автоматического управлени  работой фильтра, в котором в качестве показател  изменени  скорости фильтрации принимают отношение времени открыти  и закрыти  клапана, регулирующего подачу исходной пульпы 1.A known method of automatically controlling the operation of the filter, in which the ratio of the opening and closing times of the valve regulating the flow of the original pulp 1 is taken as an indicator of the change in the filtration rate.

Наиболее близким к данному изобретению по технической сущности и достигаемому результату  вл етс  способ автоматического управлени  работой фильтра путем его отключени  2.The closest to this invention to the technical essence and the achieved result is the method of automatic control of the filter by turning it off 2.

Недостатком известных способов  вл етс  то, что они не обеспечивают своевременного отключени  фильтров при локальных разрывах фильтрующей поверхности сеток. Это приводит к нарушению технологического процесса производства, так как ухудшаетс  качество очищаемой жидкости (фильтрата ).A disadvantage of the known methods is that they do not provide timely shutdown of filters in case of local breaks of the filtering surface of the grids. This leads to disruption of the production process, as the quality of the purified liquid (filtrate) deteriorates.

Цель изобретени  - получение фильтрата заданного качества.The purpose of the invention is to obtain a filtrate of a given quality.

Это достигаетс  тем, что отключение фильтра осуществл ют в момент возникновени  скачкообразного изменени  перепада давлени .This is achieved in that the filter is switched off at the moment of the occurrence of a sudden change in pressure drop.

На фиг. 1 представлена схема системы, реализующей данный способ; на фиг. 2 - график изменени  перепада давлени  во времени .FIG. 1 shows a diagram of a system implementing this method; in fig. 2 is a graph showing the change in pressure over time.

Способ осуществл ют следующим образом .The method is carried out as follows.

При плавном изменении перепада давлени  на сетке шток 1 (фиг. 1) за счет изменени  давлени  на мембране 2 также будет перемещатьс  плавно. Инерционный цилиндр 3 плавно перемещаетс  по подставке от штока 1. Контакты 4 и 5 при этом не замыкаютс .With a gradual change in pressure drop across the grid, the stem 1 (Fig. 1) due to the change in pressure on the membrane 2 will also move smoothly. The inertial cylinder 3 moves smoothly along the stand from the rod 1. Contacts 4 and 5 do not close.

В зависимости от характера загр знени  и режима работы интенсивность роста перепада давлени  во времени может быть различна. При нарущении режима фильтрации возможно резкое повыщение сопротивлени  сетки. При определенном перепадеDepending on the nature of the soil and the mode of operation, the intensity of the increase in pressure drop over time may be different. If the filtration mode is disturbed, a sharp increase in the grid resistance is possible. With a certain differential
