SMOKE GAS CLEANING DEVICE

The proposed utility model relates to wet flue gas cleaning devices and can be used in ferrous and non-ferrous metallurgy, energy and other industries.

A device for cleaning gases such as a Venturi pipe, including a receiving chamber, a confuser, a mixing chamber, a diffuser, Laval nozzles, moreover, the mixing chamber is made dvzhkhsection, rectangular in shape, and the second section in the input part is equipped with a device for film supply of fluid made in the form of overflow pockets with adjustable; with their blades (AS No. 1263322).

The disadvantages of this device are design complexity and a sufficiently large range of water, ball, energy carriers.

Closest to the proposed utility model is a device for cleaning flue gases containing a pipe-coag dyat. A rectangular venturi, an irrigation collector installed in front of its throat with horizontal rows of nozzles, the axes of which are parallel to the axis of the Venturi coagulator pipe and are equidistant vertically from each other, a centrifugal droplet eliminator tangentially connected to the Venturi pipe, and the ratio of the number of nozzles installed in adjacent horizontal rows the irrigation collector, in proportion to the ratio of the velocities of the dusty gas in the corresponding sections of the Venturi coagulator pipe (AS No. 2173209).

The disadvantages of this design are the difficulty of optimizing the distribution of the density of the irrigation fluid, the low efficiency of its use, increased energy consumption, high hydraulic resistance of the venturi. - The technical task of the utility model is to reduce energy consumption, increase the performance of draft equipment by reducing hydraulic resistance, and also to reduce the melting cycle. To solve this problem, a device for cleaning flue gases such as a Venturi pipe, including its receiving chamber, a confuser, a diffuser, as well as nozzles for supplying water, is additionally equipped with a flue gas cutter installed in the receiving chamber, and nozzles are installed in the confuser, and nozzle nozzles directed towards the neck in which the pantograph is installed. The essence of the utility model is illustrated by the drawing, which schematically shows a General view of the device. A device for cleaning flue gases contains a receiving chamber 1, a flue gas separator 2 installed in the receiving chamber 1, a confuser 3 in the walls of which nozzles 4 are installed, the nozzles of which are directed towards the mouth 5 of the device and a diffuser 6. A pantograph 7 is installed in the neck 5 of the device. The device operates as follows: Dusty gas from a working process unit (converter, open-hearth furnace, etc.) is fed to the input of the device and enters the receiving chamber 1. Passing through the divider 2, separation of g for two streams thus increases its maximum speed. Next, the dusty gas passes through the confuser 3 and before entering the mouth 5 of the device is mixed with water, which is injected from the nozzles 4 installed in the walls of the confuser 3. The nozzle nozzles are directed directly to the neck 5 of the device. There is a rapid mixing of water and gas. Using the pantograph 7, the gas flow rate in the neck of the device is further regulated and the mixing speed is increased. Then the mixture enters the diffuser 6, where the gas velocity is sharply slowed down. Gas.

the dust moistened with water precipitates and accumulates in the hopper (to hell, not shown), and the purified gas goes further along the technological cycle.

At the Magnitogorsk Iron and Steel Works, the proposed flue gas purification device was mounted on a JS 2 converter.

The use of the device allowed to reduce the water consumption for gas purification by 1.5 times, and the decrease in the hydraulic resistance of the device due to the lower water consumption increased the performance of the equipment and led to a reduction in the melting cycle by 2-3 minutes.
