Наиболее близким к предлагаемому фильтру по технической сущности и достигаемому результату является фильтр камеры струйной обработки, включающий вертикальный корпус с установленными в нем последовательно наклонными лотками с системой подачи воды, вентилятор, патрубки для подвода и отвода воздуха и расположенный в верхней части каплеотбойник (2). ²¹ The closest to the proposed filter by technical nature and the achieved result is a blasting chamber filter, including a vertical casing with sequentially inclined trays with a water supply system, a fan, nozzles for supplying and discharging air and located in the upper part of the droplet eliminator (2). ²¹

При использовании такого фильтра качество очистки отработанного ‘ воздуха недостаточно высокое.When using such a filter, the quality of purification of exhaust ‘air is not high enough.

Целью изобретения является повышение качества очистки отработанного воздуха за счет улавливания фильтром водонерастворимых паров.The aim of the invention is to improve the quality of exhaust air purification by trapping a filter of water-insoluble vapors.

Цель достигается тем, что фильтр, включающий вертикальный корпус с установленными в нем последовательно наклонными лотками, системой подачи воды, вентилятор, патрубки для подвода и отвода воздуха и расположенный в верхней части каплеотбойник, снабжен установленной над лотками наклонной перегородкой, имеющей просечные отверстия с отогнутыми кромками, при этом вентилятор размещен в корпусе между перегородкой и лотками.The goal is achieved by the fact that the filter, including a vertical housing with inclined trays installed in it in series, a water supply system, a fan, nozzles for supplying and discharging air and a droplet separator located in the upper part, is equipped with an inclined partition installed above the trays, which has slotted openings with bent edges while the fan is placed in the housing between the partition and the trays.

Кроме того, фильтр снабжен змеевиком для подачи хладагента, расположенным между патрубком для отвода газа и перегородкой.In addition, the filter is equipped with a refrigerant supply coil located between the gas outlet pipe and the baffle.

На фиг. 1 изображен предлагаемый фильтр; на фиг. 2 - узел I фиг. 1.In FIG. 1 shows the proposed filter; in FIG. 2 - node I of FIG. 1.

Фильтр включает корпус 1 с установленными в нем лотками 2, системой подачи воды, представляющей собой ванну 3, установленную наThe filter includes a housing 1 with trays 2 installed in it, a water supply system, which is a bath 3, mounted on

948404 4 верхнем лотке, и отверстием 4 для забора воздуха, патрубок 5 для слива отработанной воды, вентилятор 6, наклонную перегородку 7 с отверстиями 8 и козырьками 9, патрубок 10 для выброса воздуха. Над перегород- 5 кой 7 установлен холодильник, выполненный например, в виде змеевика 11, по которому циркулирует хладагент.948404 4 the upper tray, and the hole 4 for air intake, pipe 5 for draining the waste water, fan 6, inclined partition 7 with holes 8 and visors 9, pipe 10 for air discharge. A refrigerator is installed above the partition 5, made, for example, in the form of a coil 11, through which the refrigerant circulates.

Фильтр работает следующим образом.The filter works as follows.

Загрязненный воздух, засасываемый венти- ю лятором 6, через отверстие 4 поступает в ка- , нал, образованный лотками 2, и орошается водой, стекаемой по этим лоткам и подаваемой из ванны 3. Далее воздух направляется под перегородку 7 и, проходя через отвер- и стая 8, попадает в холодильник, контактируя с поверхностью змеевика 11. Пары водонерастворимых растворителей, находящиеся в воздухе, охлаждаются на его поверхности, конденсируются, стекают на перегородку 7 и по ₂₀ней через отверстие удаляются из фильтра. Пары воды, находящиеся в очищаемом Воздухе, вследствие большей, чем у водонерастворимых растворителей, теплоемкости проходят через холодильник не конденсируясь и удаляются из ₂₅фильтра через патрубок 10.The contaminated air sucked in by the fan 6 through the hole 4 enters the channel formed by the trays 2 and is irrigated with water flowing down these trays and supplied from the bath 3. Then the air goes under the partition 7 and, passing through the and pack 8, gets into the refrigerator, in contact with the surface of the coil 11. Vapors of water-insoluble solvents in the air are cooled on its surface, condense, drain onto the partition 7 and are removed from the filter through an opening ₂₀ through it. The water vapor in the cleaned Air, due to greater heat than water-insoluble solvents, passes through the refrigerator without condensation and is removed from the ₂₅ filter through the pipe 10.

Предлагаемый фильтр позволяет очистить удаляемый воздух от водонерастворимых паров, не улавливаемых водяной очисткой на лотках, а .также дает возможность вернуть улавлива емый химический реагент для повторного использования.The proposed filter allows you to clean the removed air from water-insoluble vapors that are not captured by water treatment on the trays, and also makes it possible to return the trapped chemical reagent for reuse.
