SU1247063A1 - Apparatus for cleaning dusted gases - Google Patents

Description

The invention relates to a technique for cleaning gases from dust and can be used (. Developed in the building materials industry, chemical and other areas that need to be cleaned before they are released into the atmosphere.

The aim of the invention is to increase the cleaning efficiency and reduce energy consumption;

FIG. 1 shows the proposed structure, general view; in fig. 2 is a view A of FIG. 1; in fig. 3 - axonometric image of the device case with inlet and outlet collectors.

The device for cleaning dusty gases comprises a housing 1 partially filled with a liquid inside which a rotating filter element is mounted on shaft 2, consisting of a cylinder 3, a drum 4 coaxially installed inside it with a filtering sleeve 5. Inside the drum there are vertical partitions 6 that divide it on the section. Between the cylinder 3 and the drum 4 there are rigidly connecting turns of the screw 7. The cylinder is driven by an electric motor 8. The housing contains a collector 9 for introducing the dusty gas and a collector 10 for removing the purified gas. Both collectors in the lower part are provided with windows 11 and 12 for the circulation of fluid in the cylinder 3. In the operating state, these windows are below the level of the liquid filled with a cortus. In the lower part of the housing 1 there is a collection container 13.

The device works as follows.

Liquid is poured into the housing 1 to a level at which the cylinder 3 is partially immersed in it. Using an electric motor 8, the cylinder 3 with the drum 4 begins to rotate.

Dust-laden gases enter through the collector, bend around the filtering shell 5 of the drum 4 and, having reached the surface of the liquid that blocked the space between the cylinder and the filtering shell, pass inward

the drum between the partitions 6, coming out from the opposite side of the drum 4 into the space between the cylinder 3 and the filtering shell 5

and along the helical trajectory formed by the turns of the screw 7 are directed to the output end of the cylinder 3. At each turn of the screw in the lower part of the cylinder filled with water, gases

forced to go through again

the filtering shell inside the Arabian and from the drum again into the annular space between the cylinder and the filtering shell. In this part

centrifugal particles are thrown into the inner surface of the cylinder 3 moistened with liquid and deposited on it, some of the dust is not deposited

mediocre into the water under the action of inertial forces when the flow of gases is rotated over its surface, and smaller particles are deposited with repeated passage of the flow of gases

through the filter shell. When the cylinder rotates, the pins 7 creates a continuous circulation of fluid through the windows 11 and 12 inside the cylinder and in the housing along the axis of the cylinder, and

This stream washes away the particles that were deposited on the filter shell and the inner surface of the cylinder and carried them to the sludge collector.

Availability of centrifugal cleaning,

which is possible due to the rigid mounting of the turns of the screw between the filter drum 4 and the cylinder 3, their continuous joint rotation, as well as the use

The helical motion of the gas ensures a more efficient operation of the device.

The helical motion of gases causes a lower resistance to gas firing, i.e. reduced power consumption of the device.

Immersing the working surfaces of the filter drum in a liquid and the presence of a sump allows several times to reduce the flow of liquid

bones.
