Фильтр дл  очистки газов используетс  в области машиностроени ,- энергетической, химической и нефте.химической промыш 1енности .A gas cleaning filter is used in the field of mechanical engineering, the energy, chemical and petrochemical industries.

Известен фильтр дл  очистки газов, включающий корпус с камерами чистого и запыленного газов, снабженный трубной региеткой с фильтрующими стаканами из пористой металлокерамики , прижатыми к ней ст жными элементами.A filter for cleaning gases is known, which includes a housing with chambers of clean and dusty gases, equipped with a pipe rack with filtering cups made of porous cermet, with clamping elements pressed against it.

Однако такие фильтры не имеют развитой фильтрующей поверхности.However, such filters do not have a developed filtering surface.

Целью изобретени   вл етс  увеличение производительности фильтра и экономии материала за счет развити  фильтрующей поверхности в том же объеме.The aim of the invention is to increase the filter performance and material savings due to the development of a filtering surface in the same volume.

Отличительным признаком предлагаемого фильтра  вл етс  то, что ст жной элемент выполнен полым из фильтрующей пористой металлокерамики и внутренн   полость его сообщена с камерой запыленного газа.A distinctive feature of the proposed filter is that the clamping element is made hollow out of filtering porous cermet and its internal cavity is in communication with the chamber of dust-laden gas.

Описываемый фильтр представлен на чертеже .The described filter is shown in the drawing.

Фильтр состоит из одного или нескольких фильтровальных стаканов 1, прижатых снизу к трубной решетке 2 и размещенных в общем корпусе 3. Каждый фильтростакан состоит из отдельных трубчатых элементов, выполненных , например, из листовой металлокерамики. Нижний элемент фильтростакана приваренThe filter consists of one or several filter glasses 1, pressed to the bottom of the tube sheet 2 and placed in a common housing 3. Each filter tube consists of separate tubular elements made, for example, of metal-ceramic sheet. The bottom element is filtered

Внутри внешнего фильтростакана расположен полый ст жной элемент, выполненный из пористого материала , участвующий в процессе фильтрации и состо щий из нескольких ступеней с уменьшением их диаметра по ходу газов. Нижн  at the bottom to the ring bottom 4, and at the top ends with a colp 5 with a one-sided groove. A soft gasket material is inserted into the groove. Inside the external filter-cabinet there is a hollow clamping element made of a porous material, participating in the filtration process and consisting of several steps with a decrease in their diameter along the gas path. Bottom

The upper stage has a short threaded rod 8 and a nut on top, by means of which through the crosspiece 9 the whole system is clamped into a single whole.

Фильтр работает следующим образом.The filter works as follows.

Очищаемые газы под воздействием разности давлений между камерой 10 запыленного и камерой 11 отфильтрованного газа направл ютс  одновременно к внешней поверхностиThe gases to be cleaned under the influence of the pressure difference between the chamber 10 of dust and the chamber 11 of the filtered gas are directed simultaneously to the outer surface.

Фильтраци  газа через пористые стенки идет в направлении снаружи вовнутрь дл  фильтростакана и изнутри кнаружи - дл  внутреннего фпльтроэлемента . Очищенные газы поступают в кольfiltrostanov 1 and to the colon of the stationary (filter) elements. Filtration of gas through porous walls proceeds from the outside to the inside for the filter cup and from the inside to the outside for the inner plastic element. Purified gases enter the stake
