Description

one

The invention relates to mechanical engineering and can be used in the purification of cyclic air in gas turbine installations used in the gas, energy and other industries.

To clean the cyclical air from solid and liquid particles, self-cleaning oil, 1 inertial and inertial louver 2 filters are used, which have a number of drawbacks: in the oil filter oil is carried off to the flow part of the axial compressor, in inertial louvered air is continuously sucked and in the case of a termination of the suction, the air purification is stopped.

Currently, the technique requires the purification of a significant amount of air in one unit (up to 200 kg / s), which makes it necessary to work in parallel with blocks of cyclone elements.

Parallel installation of units places increased demands on the reliability of the device as a whole.

A battery cyclone is known that contains cyclonic elements installed by Rus, and dust chambers placed beneath them, separated by inclined walls from the clean gas collectors 3.

The disadvantages of the known cyclone are that the dust chambers are common to all Rus, which creates an increased concentration of dust and an increase in pressure in the cyclone's lower russes, which leads to dust being returned, and uneven working conditions are created due to the absence of dust chambers separation. and, as a result, the cyclonic elements work is unsatisfactory, as well as the impossibility of carrying out repair and maintenance works in each floor during the operation of the structure as a whole.

The purpose of the invention is to improve the reliability of the cyclone and the cleaning efficiency by preventing particles from being carried back and conveniently removed.

To do this, dust chambers, separated from each other by Rus and separated from clean gas collectors by inclined walls, are equipped with gates and dust discharge pipes with necks arranged coaxially, and shut-off devices are installed in the clean gas collectors. The drawing shows a cyclone battery, longitudinal section.

The axis of symmetry passes through the axis OO.

The battery cyclone consists of blocks including secables joined together. The section consists of two rigidly connected planks 1, between which cyclone elements 2 are fixed. 2. The accumulator ached for accumulation ached chamber (bunker) 6 is located at the node of cyclonic elements 2 and it has an inclined wall 4, which is located in the tip area of the particles.

the bottom plate of the section serves as a roof for the slug chamber 6. b of the lower part of the dust chamber is equipped with a bolt 5 separating it from the dust extraction pipes 6 with mouths /.

In the cleaned gas collector 8, a locking device 9 is installed, which is a gate valve.

and the cyclone operates as follows.

The iipH of the gas turbine unit is polluted, air is sucked around the perimeter into the space between the planks 1, then into the cyclone elements 2n, twisting, throwing solid particles into the dust chamber, where they are deposited, and the purified gas enters the purified gas into the dust chamber.

The paclon wall, between the ashy chamber a and the collector b, is located in the zone of accumulation of particles. Due to the almost equal rarefaction in the dust chamber b and the collector ti of the purified gas, the inclined wall is largely unloaded from the pressure, which makes it neo-thick.

The cleaned gas, the exit of the cyclone elements z and the passage through the collector a, creates the incline of the inclined wall 4, which, u vclcn, didn’t ache, improve its ABw ivcHae to the gate D and reduce objvciinbiri its nose to the collector t. dust ivaivicpui o, burned by the closures o, smashed -We are one from the other. The cyclone elements jr aoOTa are uniform throughout the russam, which increases the efficiency, reliability of the device operation and allows to improve the quality of cleaning.

As the dust chamber 3 is filled with separated particles, the collector 8 of this trough is closed with a locking device 9, the shutter 5 is opened, and the extracted particles from the dust chambers 3 are removed through dust extraction pipes 6 with mouths 7 into the transport device. The location of the necks 7 dust extraction pipes 6 coaxially and separating them from dust

chambers 3 increase the reliability of the cyclone and the convenience of removing dust into transport devices from one place, especially when unloading one rus while others are working.

Boring devices 9 placed in the collector 8 of the purified gas make it possible to separate the common path of the purified gas from the collector of the purified gas of each tier, which allows

unloading of dust or routine inspection and repair in one river while others are working.
