Изобретение относитс к технике очистки газов от твердых частиц иThe invention relates to a technique for purifying gases from solid particles and

может быть использовано в энергетике дл очистки дымовых газов от золы,can be used in power engineering to clean ash from flue gases,

а также в других отрасл х промышленности , где необходима очисткагор чих газов с повышенным влагосодержанием .as well as in other industries where cleaning of hot gases with high moisture content is necessary.

Наиболее близким к предлагаемому по технической сущности и достигаемому результату- вл етс фильтр дл очистки газов, содержащий камеры , чистого и загр зненного газа с кол лекторами, секцию с фильтрующими элементами и прогревочный коллектор 1 .Closest to the proposed technical essence and the achieved result is a filter for cleaning gases containing chambers, clean and contaminated gas with collectors, a section with filter elements and a heating collector 1.

В этом фильтре газы, мину секции с фильтрующими элементами, проход т из камеры запыленного газа в камеру очищенного газа, прогрева фильтр.In this filter, gases, bypassing the section with filter elements, pass from the chamber of dusty gas to the chamber of purified gas, warming up the filter.

Однако прогрев фильтра запыленными газами осуществл етс путем байпосировани газов помимо фильтра.However, heating the filter with dusty gases is accomplished by bypassing gases in addition to the filter.

Т.е. запыленные газы во врем разогрева выбрасываютс в атмосферу, что вл етс нарушением правил эксплуатации пылеулавливающих установок. Кроме того, прогрев всего объема фильтра и самих фильтрующих элементов только через центральный коллектор недостаточно равномерен и длителен по времени.Those. during warming up, dusty gases are emitted into the atmosphere, which is a violation of the rules for operating dust collection facilities. In addition, heating the entire volume of the filter and the filter elements themselves only through the central collector is not sufficiently uniform and time consuming.

Цель изобретени - повыщение надежности фильтра при пуске.The purpose of the invention is to increase the reliability of the filter during start-up.

Поставленна цель достигаетс Тем, что в фильтре дл очистки газов , содержащем камеры чистого .и загр зненного газа с коллекторами, фильтрующие элементы и прогревочный колле1 тор, последний соединен с камерой чистого газа и снабжен устрой-, ством дл предварительной очистки.This goal is achieved by the fact that in a gas purification filter containing clean chambers and contaminated gas with collectors, filter elements and a heating collector, the latter is connected to the clean gas chamber and provided with a device for pre-treatment.

Claims

The drawing shows a general scheme of the filter (the solid arrows show the gas flow during the operation of the filter under load, the dotted lines indicate when the filter is warming up). The filter consists of chamber 1 of clean gas, chamber 2 of polluted gas of the bunker 3 of the collector of polluted 4 and clean 5 gas, the heating collector 6 with the pre-cleaning device 7 installed in it. The warm-up collector 6 is connected to section 8 with the GROUT filter and elements 9. At the collectors 6 and the 1 O valves are installed. 8 filter operation period in the filtering mode dusty gases come to the cleaning through collector C, through chamber 2 of hazardous gas and filter elements 9 and through the clean gas chamber 1 leave the filter through the collector of 5 pure gas, the Warming collector is closed at this time. Before starting the filter to warm it up, the collector 6 also opens hot, dusty gases, which have been preliminarily cleaned in the device 7, which can consist of blinds, a gold concentrator, a direct cyclone, etc. Then they are sent to the clean gas chamber in the inter-element space, thereby warming the casing and filter elements. After a certain time required for heating the filter, the collector 6 closes, the collector opens and the gas is distributed through the filter elements. The use of the proposed invention ensures the uniform heating of the entire volume of the filter and filter elements; significant reduction in warm-up time (in times); the elimination of the discharge of dusty gases into the atmosphere during the warm-up period of the filter, which increases the reliability of the filter operation in start-up modes. Claims 1. Gas cleaning filter comprising a clean and polluted gas chamber with manifolds, filter elements and a heating collector, characterized in that, in order to increase the reliability of the filter during start-up, the heating collector is connected to the clean gas chamber.

2. The filter in accordance with claim 1, tl and h and with the fact that, in order to prevent the discharge of unpurified gases into the atmosphere and clogging the outer surface of the filter elements, the heating collector is equipped with a pre-cleaner.
