(54) УСТРОЙСТВО ДЛЯ .УЛАВЛРШАНИЯ ПЫЛИ(54) DEVICE FOR. DUST MOVING

1one

Изобретение относитс к технике ;мокрой очистки газов и может быть использовано в любой отрасли народного хоз йства, где требуетс очиска газов от твердых примесей или проведени процессов тепломассообмена между газом и жидкостью и в особенности в химической промышленности ,The invention relates to the technique of wet gas cleaning and can be used in any branch of the national economy where it is necessary to clean gases from solid impurities or to carry out heat and mass transfer processes between gas and liquid, and especially in the chemical industry,

Известны устройства дл мокрой очистки газа от пыли, выполненные из пылеулавливаю1цих элементов треугольного профил , установленных с зазором друг над другом и имеющие на боковой поверхности отверсти дл слива жидкости Ц.There are known devices for the wet cleaning of gas from dust, made of dust-collecting elements of a triangular profile, installed with a gap one above the other and having openings on the lateral surface of the liquid Ts.

Из известных устройств дл мокрой очистки газов от пыли наиболее близким по технической сущности к изобретению вл етс устройство дл улавливани пьЬли 2J .Of the known devices for wet gas cleaning of dust, the closest to the technical essence of the invention is a device for trapping drums 2J.

Устройство состоит ич изогнутых пылеулавливающих элементов, установленных друг над другом, с внешне стороны улавливающих элементов установлены наклонные перегородки, образующие с боковой поверхности улавливающих элементов карманы и расположенных с зазором к их боковой поверхности.The device consists of curved dust-collecting elements mounted one above the other, from the outside of the collecting elements, inclined partitions are installed, forming pockets from the side surface of the catching elements and arranged with a gap to their side surface.

Недостатком известного устройства вл етс система орошени , не обеспечивающа достаточного контакта газа с жидкостью, в св зи с чем степень очистки газа снижаетс .A disadvantage of the known device is an irrigation system that does not provide sufficient gas contact with the liquid, and therefore the degree of gas purification is reduced.

Целью изобретени вл етс повьшюние эффективности очистки газа от пыли за счет увеличени поверхности котакта фаз оThe aim of the invention is to improve the efficiency of gas cleaning from dust by increasing the surface of the contact phases.

Указанна цель достигаетс тем, что в предлагаемом устройстве улавливающие элементы выпблнекь со щельй в Нижней части и снабжены вход щим в нее распределительнЭм устройством This goal is achieved by the fact that, in the proposed device, the catching elements are ejected from the slot in the lower part and are equipped with a distributing EM device.

5 в виде перевернутого желоба с отбортованной щелью в основании.5 in the form of an inverted chute with a flanged slot in the base.

Распределительное устройство установлено с возможностью перемещени по высоте.The switchgear is mounted for height movement.

На чертеже показано предлагаемое устройство, продольный разрез.The drawing shows the proposed device, a longitudinal section.

Устройство дл мокрой очистки газа от пыли состоит из корпуса 1 с входным и выходным штуцерами 2 и The device for wet gas cleaning from dust consists of a housing 1 with inlet and outlet fittings 2 and

5 3 дл жидкости, внутри которого размещены улавливающие элементы 4 со щелью 5 в нижней части, в которую с Зазором по отношению к стенке желоба входит распределительное 5 3 for a liquid inside of which the catching elements 4 are placed with a slot 5 in the lower part, into which the distribution is with the Gap in relation to the wall of the groove

Claims

0 device 6 in the form of an inverted chute of a reverse catching ale, a cop with flanged slot 7, distribution in the upper part. The device is movable in height. On the outer side of the elements, inclined plates 8 are installed with a gap relative to the lateral surface of the chute. A device for wet gas cleaning from dust works as follows. Fluid through the nozzle 2 is fed into the upper catching element 4 and from the gaps between the iiHM distributor device 6 and the walls of the element 4 a thin film flows into the ejector trap below to form water barriers; - The film thickness can be adjusted and moved to a height of the distributor maintaining a constant level in the trap element, there is a gap. between it and the bottom plate 8, through which the visibility also flows into the underlying element. In addition, the liquid wets the outer surface element of the gas flow, i.e. prevents dust from accumulating on the surface C of the latter; the elemental liquid is discharged through the nozzle 3. The dusty gas, passage through, Aezrry between the catching elements 4, changes the direction of the door three times, as a result of which solid particles fall on the wetted side surface of the catching elements of distribution devices, into a layer of liquid in the elements. Also dusty gas passes through the ternary water to the veil, where i is the main gas cleaning. The presence of a switchgear makes it possible to create a highly developed surface of the contact of the phases, in connection with which the dust collection efficiency increases significantly. Claims 1a A device for dust collection according to ed. No. 550169, characterized in that, in order to increase gas cleaning efficiency by increasing the contact surface of the phases, the elements are captured with a slot in the lower part and equipped with a distribution device in it in the form of an inverted trough with a flanged slot in the base. 2, The device according to claim 12, I, characterized in that, in order to adjust the thickness of the liquid film, the distribution device is installed with the possibility of moving along the height.
